Looks SERIOUS bro!


good luck w/ the project!

Thanks man. That car above is a Dart block B20, stroked to 2257cc's. It's built like an anvil and is wearing a GT4202. The passenger seat is an icebox, and we're shooting for 850-900whp. Should take about 35-38psi to get there.
I jsut started street tuning the driavablility and even off boost it's pretty fast. Just because there isnt any weight in a civic. Once you hit 6000rpm though and that gT42 wakes up- hang on to the steering wheel! 9400rpm comes up REAL fast!

stupid question bro.....

why not just spray Cryo on IC? Instead of having this? If having a cooler charge is the main goal?

or having this plus the cryo is the best way to go?


thanks much!

On the MR2 project , the intake manifold at the top of the page, it does indeed dischare C02 through the liquid side of the core.

The owner of the honda simply elected to go with the icewater. Lots 7-11's around. Not so many welding supply stores.

BTF, I asked around about this, and I was told that the charge motion valve that's part of the GDI system would cause problems when designing an aftermarket manifold. What are your thoughts on this?

[BaldTurboFreak]

I have one of th estock intake manifolds right in fornt of me and I dont see any charge motion valve. Simply a runner designed to be non-resonant.

[AaronSS]

I see that you and Aaron already had this discussion on the HPtuners board. Nice.

[BaldTurboFreak]

yup, we have free reign on intake design.
I have a few port design's drawn up in cad right now. Billet is the expensive way to do it, but it comes out PERFECT. You machine the runner's half at a time and tig them together.

[AaronSS]

You WILL do this for a FWD application. Just so you know in advance.

I happened upon this site by accident through Google in the search for water to air and particularly Laminova intercooling.
We currently have a 4 core one running in a turbo petrol 4x4 here in Australia that's exceeding our expectations and we are currently building a few others for testing evaluation. One built into an inlet manifold for another 4x4 but a diesel pumping 17-20 psi of boost. Another in a petrol engined BMW 3 series with a 3.5 litre engine shoehorned in and a monster unit 12 core one for a twin turbo LS1 Chev powered 1952 Mercury.
How well do they work? Well the 4 core one we currently have running with a boost pressure of 8-9 psi has turbo outlet temps of 82C and after the intercooler the temps are 32C so we are knocking 50C temps out in the approx distance of 2" the air travels through the core and a maximum temp rise above ambient pre turbo temps of 5C.

Very nice work!

Pretty.

We're gonna need a rather large hood scoop to shoehorn that in.

Nah. Just put it in place of that ugly stock air box. That four core integrated into the manifold is pure tits. I really think it could be done in somewhat similar fashion, maybe minus a core or two for the HHR. I'm interested in this idea mainly for straight line applications as opposed to a singular cooling solution. I want ATO to ATW with an icebox or maybe filled with CO2 to freeze the core. Have you tried that Andrew from OZ?

We haven't got into any other form of cooling as yet, we intend to try an ice slurry in the future and we have some ideas on running refrigerant (freon or similar) through the cores which Laminova say on their site is possible to achieve as well.
We want to get a few different shape configurations up and running 1st and I would also like to do some flow testing to see what configuration works out best.
I suspect the flat arrangement (we call it the pancake) will flow the best and the one integrated into the manifold will be the worst as we have to change the air direction 90 degrees through the intercooler and past that to the inlet ports.
It's all really interesting stuff to work with, I've done air to air's in the past and anyone can buy a cheap Chinese generic cooler and fit one so I'm not interested in them anymore.
We intend to get all the tech info regarding temp differential, pressure drop, flow rates etc and post them up as we have nothing to hide because we are "enthusiastic amateurs here .
We're not going to hide behind "our coolers flow 400 bhp, 650 bhp or so many CFM as it means absolutely zip if they don't tell you if it was flowed under vacuum, boost or whatever conditions.
We're having fun building these at the moment, there's basically not a lot of information available on them and how they perform apart from anecdotal so we intend to find out just how good they really are, and I have to say that at the moment they are pretty damn good.
