As I was looking for different heat exchangers, I found that OTT has a new kit out: http://www.ottperformance.com/p326/O...duct_info.html

Looks like a nice piece, especially with the drain and temp port. $240 seems like a fair price for what you get.

 

for me some links dont work and pics dont show. needs to be updated for those interested in H/E?!?!

 

has anybody ever checked out the h/e from Max Redline? thats the one i got. its really nice...

 

ottp h.e is very nice i reccomend it

 

ottp h.e is very nice i reccomend it

 

Which one? looked at the site and they have dozens??

ZZP has a group buy on this unit for $164, check out vendor's specials section

 

I agree also the Griffin 1.5 core in the stock location is excellent thats the one I use, we tested it in 04 with GM and that produced the best cooling results with 4 , 2 or single pass. But its 600 bucks. So for your money/versus performance go with the OTT exchanger - Josh and Sean are polite and treat you right...

 

I bought my Stage 1 kit and my H/e from Ott, i must say the H/e was easy as pie to put on, and hasnt come loose at all. They have awsome Customer Service, i nagged them alot but they got me threw my questions. I personally beleive in buying from a company that excels in Customer service, Oh yeah, thanks OTT, love the performance of my car, i will be buying new rotors and brakes soon as a consequesnce lol

 

Thanks for the info! Really helped!

 

I got a noob question here. Whats the difference between the typical intercooler on a turbo charged car and this heat exchanger you guys are always referring to on the supercharged balts?

nevermind I just flipped back a page and found the answer

 

I am considering the zzp stage 3 for my Cobalt SS, has anyone done any serious dyno runs with the bigger h/e to help me make up my mind. I really do not want to keep my stocker. I live in Wisconsin so it is cold 9 months outta the year.

 

I am considering the zzp stage 3 for my Cobalt SS, but i live in nothern canada, it gets cold in the winter and this is my daily drive. If i put this on it will help me in the summer but will it at all negatively affect me in the winter?

Thanks...

 

No issues in the winter, just make sure you run 50/50 coolant.

 

Can't wait to try out the crazy expensive griffin

 

haha yeah the OP is a little outdated

 

got mine and love it! iat's stay low and drop way fast after a hard pull

 

Im running the zzp s3 heatexchanger bigest one they have an the zzp dual pass end plate. I like my cooling mods HE hooked up to the stock one and my dual pass great cooling an i like it. Just unbolted my front bumper installed it and thats all she wrote

 

ZZP all the way! This is the best heat exchanger in my eyes. It's the easist to install and set up.

 

is it possible or has anyone every ran a griffin H/E with ottp's or zzp's frontmount H/E? is there enough room?

 

yes there is enough room

no one has done it to my knowledge

running any extra h/e in addition to the griffin doesn't add any benefit

 

You don't need to or want to. It will only hurt the flow to the griffin and make your iat's hotter.

 

wuld it affect in anything if i jus install a zzp s3 heat exchanger on my stock cobalt since its the biggest h/e?

 

Ok so I'm new to this site. But hopefully gonna be able to get tha hang of it. Gotta question about zzps s3 h/e, b4 I got the s3 from ZZp, I hit a fox or something driving, anyway it busted my radiator and my stock h/e, I just too the stock one off, and replaced it with the s3 ZZp. Did i defeat the purpose of the aftermarket h/e by not having the stock one on too?

 

Not really. You just replaced the stocker with the s3. Not gonna see much of a benefit over the stock besides a larger coolant reservoir
