Direction with my Ion mods

[FunkyStickman]

I've been thinking... and I know I can post up questions and thoughts here without being jumped on like a steak in a dogfight...

I'm about to sell my old '96 SL. I'm hoping to get around $800, if I change the clutch in it ($50 for parts, like 3 days for me to change it) I could ask as much as $1000. I won't sell it for less than $500, so I've got at least that much to play with... possibly more.

I'm thinking about upgrading the Ion, of course. I'm not going to slap a stage 2 kit on it... I don't think that's the smartest way to go, and I'll tell you why I think so. After I went drag the other night, the blower was ridiculously hot to the touch... and even after I had let it sit for 45 minutes, and dumped ice water on it, it was still too hot to touch. I'm thinking cooling mods would do me more good than piling on more boost. Plus, it's almost summer here, and 100+ temps are not uncommon. I think cooling mods would do me more good than anything else. Plus, my wife drives the car frequently, so it has to be streetable, and able to survive the occasional 87 octane fillup. :(

I could upgrade to the dual-pass cooler plate, but it's still limited by the stock heat exchanger... adding a Cobra HE would eat up most of my budget.

I will most likely replace the stock downpipe, for performance gains (and less detonation) and because the stock flexpipe sucks hard... for $250 I can get a nice 3" DP with a real flexpiece that won't break.

I'm debating on getting motor mounts... the cheapest route would be to get urethane inserts from Intense. Traction bars from Bwoody would be nice, but I don't know how well they work on their own.

So what I'm thinking is: Downpipe, water/meth injection, and possibly a 3.1" pulley and/or an intake.

Thoughts?

[bc3tech]

after watching Eco-mod struggle w/ his IATs, then put the cobra HE on it (i think that's what he added anyway, but i remember something about a "dual pass" so i'm not positive) his temps dropped a lot.

I'd definitely go w/ a meth setup. or you could just ditch the heaton and pony up for the LSJ procharger kit that SMP's working on :up_to_som:

i'd also not do traction bars, strictly for clearance issues. rather, get the SMMs or fill your own (that worked fine for me and is MUCH cheaper :D)

[JayCizzo]

Stage 2 is the most bang for the buck. If you do go to the track a lot the cooling mods would be a good idea. Otherwise, I wouldn't worry about it. I know a lot of people replace the downpipe, but the guy who does my exhaust work said it wouldn't be worth it. Of course he's not very versed with the our platform, he works on V8's mostly, so take that with a grain of salt. I have the traction bars and while I did see some improvement on launching I still get plenty of wheel hop. I probably need to get under there and tighten them up again.

I'm not sure if any of that helps, but it's all I got. :shrug:

No, it's all good.. I soak up information like a sponge. I'm also leaning towards filled motor mounts, for clearance and cost issues. I know how to hit driveways at an angle... my wife on the other hand, does not. For the same reason, I don't want to put stage 2 on it, because it requires 93 octane.

Then again, I'm not planning on taking the car drag racing again soon. Stock motor mounts might hold up for a while longer...but if they stay, the downpipe will likely bite the bullet. I will probably replace the downpipe at some point, for the reason that the flexpipe breaks so easily. I might wait and get a mid-length combo from ZZP or something. I haven't decided yet, my current one is holding up for now...

The extra heat exchanger isn't a bad idea, and I've tossed around the idea of how much good it would actually do. However, I can't get around the fact that the eaton is making a LOT of heat, and anything that cools down the intake charge will help the engine last longer and make more power. The heat exchanger/dual-pass endplate combo will cost around $400, and a simple meth kit would run around $250.

So which would be better? Meth is cheaper, but requires refilling. A cobra H.E. with a dual-pass intercooler endplate would cost twice as much, but how would performance compare? Would it be able to keep up?

So what about a pulley (about $200 with puller), H.E. and dual-pass (about $400) and motor mounts? Stage 2 would make more power AND more heat... but the car's not capable of using the power it already has without breaking something (clutch, downpipe, etc.)

Then again, a simple stage 2 kit would transform the car's performance, too... how do Stg. 2 cars hold up in hot climates with stock cooling?

[rlinbatonrouge]

I don't have a dual-pass plate. I don't even use my stock heat exchanger. I am using a Cobra FMIC and I switch to distilled water in the intercooler every summer. I see IAT2 temps around 20 over IAT1 when cruising that way. The IAT2's are still WAY lower than they were stock at the track and after getting on it hard. IIRC, I would hit around 140 IAT2 at the track immediatly after a run with that setup. Before, I would hit over 160 peak. Regardless, the day-to-day driving temps are much lower with my setup.

[rlinbatonrouge]

One weekend when I don't have my kids you should take the drive down here and spend the day. I'll let you install my traction bars and see what you think.

I can speak to this. I've had my stage 2 on with stock cooling since late 06 with no issues. I live in Tampa, Fl so I'm no stranger to hot, humid summers. I should clarify, I don't actually have the GM stage 2 kit. I have a BF 2.9 pulley, 42.5 lb injectors, stage 2 belt, and I'm HP tuned, so it's actually a little more aggresive than the standard stage 2.

One weekend when I don't have my kids you should take the drive down here and spend the day. I'll let you install my traction bars and see what you think.

LOL, Now there is a deal. :deal:

[bc3tech]

personally i'd start w/ the cobra HE w/ dual pass plate. less complicated, no refills, and i can tell you from what i've seen, it does a damn good job. and i saw it on a stg2

[FunkyStickman]

Awesome... all good input, guys. I'm going to digest this for a bit, and if I think up any more questions, I'll post 'em here.

You guys rock!

And as for the deal... all I gotta say is :bubbrubb:

[rlinbatonrouge]

I'll be sending mine back to Bwoody in the next week to have them rebuilt, so I'll need a few weeks before you come up and try them out. 2 years of Louisiana summers and winters have taken a toll on the hardware and they are going to re-certify them for me. I have an empty street behind my house where I like to test my car, it's about 1/4 miles long and deserted. They were planning on the second filing in my subdivision, paved the streets, but then the market fell and there isn't anything built out there. You can hit about 60-70 before having to brake for turns. That should let you get a real good feeling for launching the car with them on.

[MGM1979]

IMO, you're on the right track - no point in adding power if you can't keep the engine cool enough to maximize those power gains. That said, cooling is a must.

Before you go spraying anything though, I'd go with the suggestions previously mentioned...run dual H/Es inline with a dual pass...that shouldn't cost much more than $300 if you shop around.

I'd leave the traction bars out of the picture and go with filling mounts for now...with a stock pulley, you shouldn't be at a REAL point of traction needs - beyond what your foot can already provide.

I'm not sure why I posted at all...think I just spit out exactly what BC3 and Cizzo already said - oh well.

You posted cause you wanted to tell me what you thought about it, which is why I started the thread. Thanks. I'm still working up a budget, but I won't have a final figure until I sell the old car.

As with the rest of life, the BUDGET will dictate the direction you go...report back when you have numbers, and we can re-hash all this again to make sure you stay on point (and slower than me...LoL).

The extent of your RL knowledge that you could/would pass down to him involves two supercharged women's breastssssssss.

Not that there's anything wrong with that, just that it'd be hard for him to improve his 1/4 mile times with those "distractions" in his face...if you know what I mean.

[FunkyStickman]

You know, reading RL-BR's post, I did some research on heat exchangers. Afco makes a huge dual-pass unit that fits in a stock Cobra... it's about $315, which would be cheaper than buying a dual-pass endplate and an extra HE and would probably work just as well... I'm starting to get some ideas here! That would probably take case of the temps...

there's the ticket! thinking outside the box FTMFW! get that ish. at the very least you will probably be able to re-sell it if it doesn't fit for damn near what you paid for it, then you just paid for experience and that's priceless anyway :D

The only thing i'd worry about is yeah, that fit's a stock cobra, but do ppl use the cobra HE on the RL because it just fits in the car? maybe there's not room for that larger one on the LSJ. just something to think about, maybe try and get measurements of both first.

If I can get dimensions from AFCO, then I can measure the space in the front bumper and get an idea. I'm all over it.

[MGM1979]

interesting...raises a question...dual pass FM H/E vs dual pass intercooler - what's more effective, by itself?

Like BC3 said, it's worth the experience alone to find out...

you know, forgot to mention, the dual pass requires a surge tank if you plan on doing it right, which would tack on some more money for the tank/plumbing...that said, I like the AFCO experiment!

For the record, my "cooling" plans always called for the dual pass endplate + dual pass FM H/E to replace the stocker altogether (plus injection). You're on par...I gotta get with BWoody to see about that H/E though - I bet he could do better, AND fit it properly for our cars...

That's what I was thinking... I'm not going to a tiny pulley, so I don't think overkill is necessary.

[rlinbatonrouge]

I've always liked the Afco setup personally. Plus it has a drain plug that makes life so much easier....

[Cat Ion]

Then again, a simple stage 2 kit would transform the car's performance, too... how do Stg. 2 cars hold up in hot climates with stock cooling?

Between Southern AZ and Southern NV trips twice on stg 2 with zero problems. So you have a humid heat example and a dry heat example to work with. I have to support the comment posted earlier that if you don't "frequent" the drag strip, a stg 2 car will hold just fine. If you're not dropping the hammer and forcing the clutch/axles/tires to pop loose, the stg 2 is definitely a good improvement.

Is there a difference between an FMIC and and FMHE? (asking for knowledge, not challenging here).

The only thing i'd worry about is yeah, that fit's a stock cobra, but do ppl use the cobra HE on the RL because it just fits in the car? maybe there's not room for that larger one on the LSJ. just something to think about, maybe try and get measurements of both first.

I think that's exactly the reason the Cobra HE is used, because it fits. Get measurements on the Afco for certain!

[bc3tech]

Is there a difference between an FMIC and and FMHE? (asking for knowledge, not challenging here).HE is a water->air cooling system, while IC is an air->air cooling system. Since the RL utilizes water->air in the first place, the HE is really the only way to go if you don't want to mod the stock system.
or at least that's my understanding of it.

[rlinbatonrouge]

IIRC, the Afco's have been installed on some 'balts. I don't anyone has put one on a RL yet.

[FunkyStickman]

They actually make 2 replacement Cobra heat exchangers, and looking at the pictures, the dual-pass looks like it's a bit wider than the single-pass (which itself is the same width/height as the stock Cobra one, but twice as thick).

[Doc]

I switch pulleys like some of you guys switch underwear. Seriously, I have a 2.5, 2.6, 2.7, 2.8. I only have a stock cobra HE and my IAT2's rarely spike (above 145). On a normal day the IAT2 temps are anywhere from 12-20 over IAT1/ambient. So, I think a stock cobra HE would be fine in this case. The upgraded cobra HE's will fit, you just have to get some way to mount it. There isn't a lot of clearance but they fit.
If I was starting with a stock car and looking to up my performance, I'd go with a stock cobra HE, make my own dual-pass endplate (requires one fitting to be welded), a 2.8 pulley and 60lb injectors. I would also invest in getting someone with HPTuners to spend some time with a wideband to get my fuel right and also to get the MAF in line. The reason I pick a stock HE from the cobra rather than the replacement is the cost. It works great for the cobra guys but I personally haven't seen the performance difference to warrant spending $200 more. As far as meth goes, I'd avoid it....its habit forming ;)

[Doc]

oh....btw, there are plently of people who have pulley pullers that you could borrow.

[rlinbatonrouge]

It's the weather down here and the humidity. Before the FMIC I'd hit 140 just sitting in traffic for IAT2.

[Cat Ion]

Guess that makes me want to get this done to mine too, since I play around in desert temps most of the time.

[rlinbatonrouge]

It's not just the heat, it's the humidity. I spent some time in the Mojave Desert. 120 during the day but 2% humidity. That was some of the best weather I have ever been in. Down here, 90 during the day and 75% humidity is unforgiving.

same situation in the midwest as well.

[MGM1979]

don't you go comparing midwest humidity to that of the south-southeast...the humidity down there is absolutely retarded, COMBINED with 80-95 temps

[FunkyStickman]

Yeah, I know I could slap a stage 2 kit on and call it a day... but for the reasons stated, I don't want to start there, because if I do, I'm going to put more strain on the car than I feel is good for it. It's nothing for heat indexes to go above 110 here, and you have to run A/C in that kind of heat... I just don't want to take the chance. Granted, if I get enough money to play with, I can buy HPTuners and mod as I please, and make it run right as I go. But for now, I'm going to maximize the power that's already there... no use wasting it if it's already capable of making decent power, right? Intake/exhaust, extra heat exchanger, slightly smaller pulley. These mods won't hurt later on when I go to a stage 2/3 either.

And with the pulley puller.... I don't know, I may just buy it so I'll have it if I need it. I like to have tools when I need them. I could always buy one later, too. Other things, though, like the motor mounts... I don't mind trying something cheap (like filling them with rubber sealant) if it works.

[bc3tech]

...These mods won't hurt later on when I go to a stage 2/3 either...keep in mind stage 3 locks out HPT and also disables your A/C. i do have to say that the "on demand" rev-limiter setting is pretty pimp though, esp after seeing it in action :D

[FunkyStickman]

Yeah, it is... and some of the guys on CSS.net have overridden the A/C disable. But, for what the Stg. 3 ECU costs, I'd just as soon get HPT and learn to do it myself. Plus, I can have different tunes for different conditions with HPT... I'm not locked in. I'll definitely consider it.

as far as diff tunes, stg3 also has the "high octane mode" for 100+ oct gas... makes the car a freaking beast, too.

http://www.cobaltss.net/forums/showthread.php?t=76479&highlight=stage+a%2Fc

Basically, just hardwired the A/C compressor relay to a switch in the cabin. Plus, the stage 3 comes with the wiring to hook up a 50-shot, and the tune to go with it... plus on-the-fly high octane and adjustable rev limiter mode! it's tempting, believe me. But my car couldn't use half of that power.

Could you see the look on their faces when I say "it's 100% factory parts!"

[italianjoe1]

If you are looking for a dual-pass endplate, I have a couple I made up for sale.

[FunkyStickman]

No kidding?? They modified stock pieces? I'm very interested...

[FunkyStickman]

***UPDATE!!***

I finally sold the old car. I got $600 for it, plus $100 I'm getting for my birthday Monday, so I've got $700 to play with.

I've agreed to relieve RLinBR of his HPTuner setup, and I've also been offered a combo deal on poly trans mounts and a BWoody rear strut bar for $80. So I've got a few hundred left over to play with... should I get some 42# injectors and learn how to tune? Or should I get a FMIC and tune to maximize the power that's already there?

Definitely gonna take you up on the offer to try the T-bars, though...

So this thread is back on!

[MGM1979]

I say cool and tune what you got, before you go adding more power...especially while you're learning the ways of HPT

[FunkyStickman]

Dude, the weather was so hot this weekend, I thought about how much hot air the car was getting... I'm stalking a heat exchanger on teh ebayz that's ridiculously cheap (I'd link to it, but I don't wanna get sniped!)

If I get it, I'm going to have to think of a cool stencil to write something on it. Maybe "Got Boost?" or something ricer like that... any suggestions?

The one I saw with "Genuine GMPP Parts" was pretty slick looking, that would make people scratch their heads.

Anyway, there's only about 2 days left on it, I'm trying to get it for less than $200... it's worth over $330 new! New dual-pass Afco unit for Cobras with cosmetic defects.

IF YOU SNIPE ME I WILL KILLLLZ JOO! :D

[FunkyStickman]

Nope, none of those! *whew* thought I was gonna hafta kill somebody for a minute there.. LOL

Yeah, Matt, I was thinking about it. Which day would be better? Saturday, or Sunday? Saturday's better for me.

[rlinbatonrouge]

Either oene for me. I'll tell my fiance and she can go dress shopping. We shouldn't have the kids this weekend.

[FunkyStickman]

Awesome. I've got Prothane tranny mounts and a BWoody rear lower strut brace coming in the mail, gonna pick up HPT from Matt this weekend (and I need it, the car's still throwing codes and occasionally stumbling at idle) and I'm going to try to pick up a dual-pass heat exchanger on ebay in the next 2 days... I'm gonna be rocking, people!

I might do a few other cheap mods... I'm thinking a "Dixie" air horn might be appropriate? LOL!

Oh, as an extra thought, I could actually get a dual-pass intercooler endplate and switch them around to see which setup works the best, once and for all.

Stock/DP exchanger in series, DP exchanger alone, DP endplate and stock/DP HE in series, or DP endplate and DP HE alone. Or even DP endplate with only the stock HE.

Wouldn't you guys like to know 100% once and for all which is best?

[rlinbatonrouge]

That reminds me, I need to tune out my SCIP this weekend.

And we should be fine. What time were you thinking about?

[FunkyStickman]

Probably leave the house around 8:00 or 9:00. I'd be at your place around 9:30-10:30.

You have destroyed my gamer honor. We must duel to settle this. What is your game of choice? Choose wisely, my friend...

[rlinbatonrouge]

Hmm, I'll have to go with Curveball or Adventure Golf.

Oh, haha. I really don't play any games when I am at home. I still need to hook up my internet at the fiance's house. I used to play PS2 with her son, but he's gotten into GH and that isn't very interesting to me. The last game that I enjoyed playing online was Enemy Territory, and that was a few years ago. For the most part, I'm not a big online game guy.

I will still take back my Donky Kong score. Just wait.

LOL... I did it, too!

Okay, well I finally got the Prothane inserts in last night. Initial thoughts: I won't need quarters for those vibrating hotel beds anymore... the first time I cranked it up I was thinking a bolt was loose, cause the car was shaking so bad. No loose bolts (downpipe bolts don't count) they're just that stiff! Granted, after driving out to Baton Rouge to hang out with Matt and driving back, they had settled down a bit. I'm still not sure the wife will like them (she very well might!) but they work like a charm. I did a couple of takeoffs, and zero wheel hop... the tires just spin, then chirp and grab.

[Cat Ion]

Sweet! Take your vibes and magnify by about 5 and you have solid motor mounts! They will mellow out a bit more and you'd be surprise....she might really like them after all. My wife HATED the SMM's when I first put them on. Now she drives mine over her Outlook, mainly for the gas savings, but she has yet to complain about the vibes. Enjoy the smoother launches!

[FunkyStickman]

Thanks, I'm already enjoying it. My dad really thought Matt's exhaust cutout was cool... he's asking me about putting one on my car now! LOL

I told him "I just fixed one exhaust leak, now you want me to make another on purpose?" Actually... would be kinda cool...

[Cat Ion]

What is this you speak of? Not familiar with this cutout.

[FunkyStickman]

RLinBR has an electric cutout in front of the left rear wheel. It's loud. It's teh awesome.

[Cat Ion]

ok, like an exhaust dump to scavenge quicker during drags?

[MGM1979]

my exhaust dump is my 3" CTI header-back (and flanged cat delete)w/straight through muffler. I had originally picked up an electric cutout as well, but we couldn't find a good place to put it with the piping being so damn big.
