I say do the cooling first. Your supporting mods will set you up so you don't fail. Plus you will get faster by just adding some cooling stuff. Take it from someone with the experience.

 

I think a 3.0/2.9 and 42's and a street tune will net more gains than just doing cooling mods alone, no?

I really don't want to dick around with meth/water injection. A heat exchanger is good to have, yes, but is it really necessary for a daily driven car with 42's and a 3.0" pulley? Thats similar to GM stage II, and I havn't heard of one problem with that setup. Or say I just add the h/e alone. That, IMO, won't give me much power at all compared to pulley/injectors IMO with a street tune. Or at least it shouldn't.

I don't want this to be a track king. Basically what I want is a daily driver with a little bit more "pep" than the stock ss s/c. And I think that pulley/injectors are the answer here.

 

I'm faster than all the 3.0/2.9 cars with 42's around here. and I'm on stock pulley. They'll be crying when I add the dual pass, header and downpipe, and up my meth mix to 75/25.

 

Without using meth, what would you say the best route to take is to gain the most power?

 

all you have right now is airbox mod and catback wih stainless muffler right? Cheap easy mods to make you go faster.

Buy the CXRacing h/e off ebay. 200 bucks including parts from home depot.
Buy a 3.0" modular pulley system from nate. 100 bucks
Header and downpipe combo. $$$ depends on what you get
Custom tune. $$$ depends on who does it.

Just remember when you are at the track, let the car cool down for about an hour in between runs and put ice on the blower to achieve best times.

FYI, I trapped 101 on street tires with nothing more than a raised rev limit, cobra h/e, and a cutout. Stock I only trapped 94, so that's a 7mph gain.

 

i would buy 60s and a 2.9. and if u want to go smaller u wont have to buy another set. plus at 2.9 your going to be maxing out your 42s or close to it

 

Ya.. I trapped 100 with just airbox mod, catback, and 7k rev limit. I am very short on cash right now, which is why I wanted to go with a 2.9 or even 3.0, 42's, and a custom street tune by paul (06blackg85ss). What do you think of that setup?

 

I would get 60s over 42s but that's just my opinion. You can run a 2.9 and be safer as with the 42s u will be maxing them out.

 

7k rev limit?

So your 220whp at Synapse wasn't just with an intake/catback then.

 

You're just jealous because he made a little less hp/torque then you with barely any mods

Just kidding man.

 

42s are a waste on anything smaller than a 3.1" pulley. I've seen plain old stage 2 cars out run the 42s (mine being one of them). go with 60s and get tuned by someone who knows what they are doing.

idk what pulley im goin with yet, but i have 60s and i am tuned well. i no has cooling mods yet ive had all kinds of different size pulleys
2.75" (60# injectors in 30 deg. weather)
3.06" (42# injectors)
2.9" (42# injectors WAY beyond their capacity)
3.06" (60# injectors)
2.8" (60# injectors)

nothing really made a major difference in 1/4 mile times and probably wont until i get some serious cooling mods

 

truth. it hurts.

 

I agree that cooling mods are the best way to go. Speaking of which, ralliartist, do you mind if I pm you and talk to you about some things?

 

Yes it was. I made 212-215 @ 6500, 220 @ 6800.


I'll probably go with a 3.0 if I get 42's. 2.9 will be with 60's. Does anyone know where I can get injectors for a good price?

 

ottperformance.com has them at a decent price. However I did not like how they shipped them. They put them in a zip lock bag, and put 4 injectors in there.....sweet. I hope to hell they are flowmatched.

 

Hmm...

 

I am sure they are flow matched, but I just don't like the whole zip lock bag thing...I thought it was kind of lame. They should be putting them in something a little better then that. But thats just my 2 cents.

They are a good vendor however and will work with you. I would purchase from them again, but I would ask any questions I have over and over to make sure what I am ordering is right.

 

I might go with those 60's and a 2.85 polished pulley if the price is right. I am doing a ton of shopping around so I am looking for the best price possible here.

 

the 2.85 pulley from them is the same as it is from nate, so just order it directly from nate that way there is no confusion. I was pissed when i ordered my 2.8 inch pulley from ottperformance and it didnt come until a week later because it was shipped from nate.

I would go with a 2.8 instead of a 2.85, not much of a difference.

 

Yeah. With no cooling mods though I might even go with a 2.9. *shrugs*

 

if your not going to get cooling mods, then dont drop pulley sizes. Your car will be faster with cooling mods and a larger pulley, then no cooling mods and a smaller pulley because you will heat soaked.

 

I don't want to do meth injection, though. So that rules that option out. Only other options are injectors/pulley, which will net better gains than just a heat exchanger. *shrugs*

 

Why are you against meth injection? Injectors and pulleys are great, but without the cooling mods your not going to see the gains you should be seeing. Hence why rali can run a 13.6 with just cooling mods on the stock pulley.

Cooling mods > pullies because we heat soak. People really need to realize this. You will not see the gains you should without cooling mods. Your iat2s will be through the roof, and after a few pulls you will be LOSING power.

 

You have to remember this is my daily driver. If anything I do a few "blips" of the throttle in 2nd, and that's about it. Every once in a GREAT while I will do a WOT 2nd to 3rd run when merging on the highway. That's about it. I take it to the track but not on a regular basis. Basically what I am looking to do is (safely) add a little more zip to my car for daily driver status. I am looking to perk up the midrange powerband, and the only way to do that IMO is with pulley/injectors. GM S2 alone has some great gains from that.

 

I would skip the stage 2 because the tune is crap, but the power increase is nice yes. If you want to gain a little more zip then you are going to have to save a bit. Because you are not safe to run a 2.8 and 60lbers with no cooling mods. Plain and simple you need AT LEAST a heat exchanger man.

Cooling mods will allow you to use the power that you have. If you drop to a 2.8inch pulley you will have more power yes, but you will have much more heat, and you will end up losing power.

My car is also my daily driver, and I have driven her cross country. Iowa to cali, back to iowa to chicago and back many times. I love this car to death but the best things I have ever done to it have been the cooling mods. Keeping the car safe, is keeping the car cool.

I recommend the following for what you are wanting. 60lbers, 2.8inch pulley, a tune, and a heat exchanger. I also recommend meth, but if you can't afford it, then save up, and then get it.
