my car was in a crash and the s3 heat exchanger was damaged just wondering what one i should get to replace it im plnning on runnning it with the stock one not replace it any help guy?

 

what would u guys get?

 

I know you want another replacement front mount heat exchanger, but if something ever happened to my OTTP "gen 4" front mount heat exchanger, I would no doubt purchase a Griffin heat exchanger. The Griffin replaces the stock heat exchanger, and is far better at cooling than any front mount or combination of front mount and stock.

 

what makes the griffin so much better

 

In general it's a large heat exchanger with more fin area & larger end tanks than any front mount heat exchanger on the market. It's over twice as thick as the stocker, its true dual pass design make it very efficient at cooling.

 

i still havent seen logs of temps to prove this. Ive talked to a few guys and their temps werent any lower than mine for me to justify spending that kind of money.

 

lol so what is the better choice

 

i love my zzp s3....just saying

 

Speak to John Powel about it. He has been running one on his Redline since 2004.

It's proven its self in GM Racing testing, but they will not release any of the lab data. There are a few members on this site with one, but they have never provided any information either.

I love my OTTP gen 4 heat exchanger.... just saying.

but if anything ever happened to my heat exchanger I would for sure ditch the front mount setup & purchase a Griffin.

 

ive spoke with a few about it that have one. And im not inclined to spend almost 600 dollars on a HE that i have just as cool iats on. So until i see actual data i would go with the ZZP one again. But your choice. On my ZZP stage 3, with gm dual pass, and opt B i see about a 19degree difference between iat1 and iat2. WOT i have meth so i couldnt compare iats after the pull with a car that doesnt. My temps also recover pretty quickly on the track. A certain member on here bought one and has it intalled and is seeing a 30degree difference.

 

I to have about an 18-20 degree difference between IAT1 & IAT2 with my OTTP gen 4 heat exchanger & opt. B. I've had no problems with it since I installed it, and actually like it alot.

I'm not trying to start an argument. I'm going by what I've read, and learned through John and some engineers with GM about the Griffin. I'm also in the process of building my engine up to Time Attack specs (already have the blower), and want to try and use almost everything GM Racing has used. That's one of my other reasons why I would replace my heat exchanger with a Griffin if something were to happen to it.

The ZZP S3 is a great heat exchanger for the money & gets the job done very well, as does the OTTP gen 4 heat exchanger. Hell, start using E85, and you can eliminate alot of the cooling mods like aftermarket heat exchanger and such. Just look at what WSFrasier has accomplished with the stock cooling system.

 

Oh i know man wasnt arguing either just stating the data ive seen on my setup and what ive heard talking to the guys that have the griffin. I just couldnt justify the difference in cost with no data. Everyong was like zomg griffin heat exchanger and no one has bothered to datalog the car or post results. And from what ive heard theyre not very cooler ( some temps were higher) than mine. And once i have e85 here i will be ditching the meth but until then im stuck.

 

This.

I would for sure datalog/post results of my car if I ever dish out that kind of cash for a "in theory" superior heat exchanger.

 

thanks alot guys i will most likley just get gen 4 or s3 great info here

 

You're welcome man.

 

this is going to sound really stupid but I believe the gm time attack cars also used the aluminum air dam. something that every one is under estimating. I can move my stock air dam with my finger that means anything over like 30mph it would deflect less air.
aluminum air dam would not move, it would push more air, more air moving over the heat exchanger would mean better cooling coefficient. better cooling coefficient means lower coolant temperature, lower coolant temp means lower ait2. do i need to go on?

 

afaik the air dam is used to direct air at slow speeds. at higher speeds it isnt needed since there is more airflow going to it. make sense?

 

that makes sense isnt there one that is suposed to make the air flow over the sc as well? i think my car is missing that

 

i never heard of that. my car doesnt have it

 

I finally have some real comparison. The IATs are not the biggest issue, it's how fast the intercooler system can draw heat away when it's under full throttle at higher RPMs.

I have a TVS charger and went to a 2.85 pulley so I could do more track time. With the Griffin I can push it to 6000 RPM at WOT with only slight increases in boost pressures (due to heat soak). A friend of mine just got a TVS with a better exhaust than mine same dual pass IC coolant loop. But he has stock intercooler radiator with an external additional heat exchanger. With the 2.9 pulley in WOT pulls he is starting to max out the boost pressure in one pull much faster than I did even with my 2.75 in place.

So if I was doubtful before I am a true believer now in the Griffin's power to get rid of the heat.
