I hit that darn Raccoon and still have yet to get the car back from the shop.

Check out how massive this ZZP HE is. I excited to see some IAT2's now! I didn't even have a HE in the first place as E85 could care less....















They said the RKSport bumper and everything else will be done and ready for pickup by this Friday.

 

holy hell that thing is enormous. no need for a s3 h/e i presume?

 

NO NEED AT ALL!!! LOLZ. ZZP claims is bigger, better, and more awesome than the Griffen and so far I agree. And it's cheaper!!!

Even has it's own fill spot. So now no need for a Option B tank as it will bleed air to the top.

 

Very nice piece. ZZP did a good job with this, would love to see the comparison between this and the Griffen

 

iat2 pr00f?

 

I think I'll be the first with proof. Have yet to get the car back. I'll probably have proof around the 7th of next month or so. Maybe sooner, but I doubt...

 

if IAT are lower than its def on the "to buy list"

 

I like the fact that even though the turbos have been out for almost 5 years they are still hooking up is supercharged guy

 

Hmmmmm.

Want to say I read somewhere that Powell had shown negative effects of stacking units hence why griffen was a replacement and not an added piece such as most of us use. Could be wrong though.

 

Everyone that I have known to use an additional heat exchager with the stock HE reported an improvement in IAT2s and recovery times. As long as they have everything connected properly and everything is functioning, I don't see how this could be a negative effect. The Griffin is probably better though when it comes lowering both, and just does it with one heat exchanger instead of using two

 

Yes but heat exchangers don't even cover half of the units behind them. I'm not saying ones right or wrong just trying to bring reference to what I'm trying to remember that I read. Hopefully john can jump in here and chime in

 

The one behind it is the ac condenser, and it replaces the OEM heat exchanger if I am not mistaken.

 

Wow seems like this got off track and people are a tad confused.

In order from front to rear:
ZZP Stealth
AC Condenser
Radiator

The ZZP stealth replaces you're stock HE just like the Griffen, but it is now located at the far front...

 

My S3 and flow through hold about 4 liters and barely gets lukewarm, its a nice piece if you swap it with the stocker i suppose.

 

I am guessing this unit is what you wanted, its at least as good as a fmic s3.

I am sure the OP will provide the data from his fmic s3 and this one.

Not running an option B with it, is just weerd. Every cooling system for the engine on every car out there has an "option B" style bleed line. On the LSJ and LNF its right out of the head beside the ect above the top radiator hose

 

I never had a S3 he... Sorry.
I'll say with my Dual Pass and Phenolic(on stock LSJ HE) my IAT's maxed around 148ish after a long pull. with 70-80* temps outside.
I'll see how this does over the stock LSJ HE, as I deleted the stock one.
I have a ported Intake Mani now as well..Which should decrease IAT2's even more as more of the laminova's surface area is available.

 

GM spent a lot of time on the Laminova, and making the slots too big actually were found to detract from cooling; for the race cars we were anxious to do that, and just like the windtunnell has taught me, what we think intuitively doesnt always apply. I presume in this case, it is a point of the air not staying in the cores long enough to transfer heat effectively , this all measured in milliseconds. I am not sure if folks have an appreciation for the time , effort engineering and money GM spent on these systems, whatever they are and whatever generation of engine it is...

I am prepared to take bets that this new cooler is not, in fact as good as a griffin, for all sorts of reasons already covered in the past on this forum. I think that the new h/e will probably match the s3 that ZZP make. And cost way less than a Griffin.

The fabrication quality out of ZZP's fab shop looks tobe excellent. But there is some cooling engineering needed, and Zoomer may know all this, he has dissected enough of these systems already and has a lot of experience bringing things to market.

 

Then you would be claiming a ported intake mani would mean more HP since the air is flowing better. I think I understand where the restrictions are in our cars and I'd say more contact is good air isn't flowing any better into the motor use to that... it's a set psi due to the blower.. While I think any gain to either side is minimal at least it's something..

 

What do you mean its a set psi due to the blower?

 

The blower spings at a set rate meaning nearly the only ways to gain power is to make something more efficient which I think a ported intake mani won't be for better hp as I don't think any more airflow will occur into the motor, only more of the laminova exposed meaning better IAT2's. I'm pretty sure someone already proved this... It's not an amazing difference, but it's something... I got the Ported Intake Mani for free and came with a ntp port.

 

Blower speed is creating flow not psi which is why i was confused. Pressure is the resistance to flow.

 

Yes I know I know. Technically the pressure is created in the intake mani on our cars. The blower is creating airflow but since it's a set speed you can only improve so much... Example Intake and exhaust don't even get close to hp gain that a simple pulley down will...

 

Cant wait to see the iat2 results, i like powel but honestly i think he is gonna be wrong about this h/e, zzp wouldnt waste time and money to develop an replacement h/e thats not better then the stg 3 h/e that is way cheaper.

 

sub'd for results. ZZP already have them I am sure.

 

The only way I can see it being the same as the S3 is because I have deleted my OEM HE while the S3 keeps use of it....

I mean if you look at this thing, it's pretty much 3 S3's mounted vertically and all together.....
