"Hey guys, I totally rigged my H/E to the front of my car and now it fell off, do you think i should try zipties now or duct tape?"

 

Your being sarcastic right?????

lololololol

 

lmao! omg, who only bolts 2 of 4 holes.. :facepalm: I hope everyone pointed and laughed when they saw that **** go down...

 

The core I posted was their 3rd one which was supposed to be the end all be all bad ass core of cores. Are you saying they have a 4th version which is NOW the best, bad ass core?
-The unit listed on their site in pics and specs is the one I posted a picture of.

Yep, here is the new one. They haven't updated their site yet I guess. Like I said, my buddy just got his from them last week, and this is the one we installed. Josh, if you want these pictures down, let me know.

 

Myonly rant on the ZZP is the plastic 90's dont get me wrong they work great but I see them getting replaced by a metal 90 in the next couple of years.

 

It's still a chinese core, although this OTT 4th gen HE appears to be better than the 1st, 2nd and 3rd gen units.

 

That one looks very nice.

 

This is the one I have, bolts up nicely to the crash bar.

 

Any chance of you guys changing the 90 degree connectors to metal in the near future for you h/e. I have put in and love thats the only thing I can see going wrong in the near future or was there a structural reason for them being plastic?

 

We build everything in house so if you explain better, I can make a change as long as there is no down side.

 

He would prefer the plastic 90* fittings on the H/E to be aluminum.

 

The 90 degree hose connectors that are in your kit are made of plastic. I just simply recommended using a metal 90 degree hose connector the screw in type.

I would prefer that or brass something that wont brake if heated frequently.

 

The plastic elbows started leaking at the threads after being on my car for 7 months. I'll try to take a picture of what they looked like when I pulled them off. That plastic is so thin and cheap, they both actually melted and deformed slightly into the shape of a kidney bean...

 

Teflon tape on the thread helps I dont know if you put any on there or not with the leaking but reshaping I have never seen. Guess I will when you post pics.

That and when you ship it it should be in its own small box that way the fins dont get bent as I had to take and extra 1.5 hours to straighten the fins on mine as so many were bent or smashed in.

 

Mine doesn't leak after about 1 year, but I wouldn't mind replacing the plastic elbows with something more sturdy.

 

This would be our 4th gen heat exchanger. I'm sure we will have a 5th gen in 6 months again, I seem to always find someway to improve the design.

 

When will this 4th gen be up on your site for sale? I only see the 3rd gen.

 

It replaced the 3rd gen, so if you order the one on the site you will get the 4th gen.

 

Here's a pic of what the plastic piece looked like when I pulled the hose off. Sorry for the crappy picture... iPhone camera + morning pre-coffee jitters = blurry pic.... It looks more like a D than a bean, but it's still more deformation than I'd like to see.

 

YOU find a way to improve the design? You're reselling mass produced Chinese parts, I don't see how you can claim to be improving a design you have no involvement in. It would be more accurate to say you 'always seem to be finding a better design'

 

You think it's by chance that this heat exchanger perfectly fits in the grill? It's not because I designed it in solid works and had it made to my specs. It's really not that hard to have something made.....

 

Josh, the new H/E is very wide. It's wider than ZZP stg 2/OTT 2nd gen (AKA Chinese air to air core) that I have on my car.

Zoomer, I would recommend switching to aluminum 90* fittings for the heat exchanger. I haven't had problems with my plastic ones, but that's probably because I'm very careful around them knowing they could be fragile with all of the heat cycles that it endures.

And a recommendation to both of you, maybe make a shroud that holds 2 electric fans and make that a different (more expensive) model of the heat exchanger. I mounted some frozenboost fans on my heat exchanger recently (with no shroud), although I haven't had a chance to do some IAT2 testing, I seem to believe it will significantly drop low speed IAT2 temperatures. This would be attractive to the drag racing crowd. The GT500 guys seem to have good luck with puller fans on their heat exchangers. Having an aftermarket heat exchanger doesn't do DICK at low speeds or when you're stopped. That's very frustrating for drag racers.

Having a shroud that they are mounted in would make the install much nicer looking and you wouldn't have the black straps that go through the heat exchanger (like they make for radiator fans) to hold it on.

Here's my slightly hillbilly setup:



Here's the aftermarket GT500 H/E with shroud and 2 fans.
