lets talk intercoolers again...

Goes up to 112c...keeps going...so I dont stick around to find out how high it goes. Once I back off & do a lap at 100kph it dropes to high 80s pretty quickly.

Keep in mind I dont have very good ducting to my oil coolers...they just sit behind the holes in the bumper....I have yet to seal them off to help the air through them...so this will be playing a big part in my temps on the track.

Once I get that sorted I will post the results here....could be some time though as I am broke at the moment.

Reason for no ducting is that I have not found the right type of material that I want to use for the ducting. Also Im thinking of setting them back further to create that traped ram airflow as I intend to do with the IC.

With our V mount we dont get high water temps at all on track even on hot day\'s with a greddy underdrive kit.
The air temps are usually in the 30c area but water stays around 85c to 90c.The intercooler is not massive,but is pretty efficient.

A pretty good rule of thumb for an intercooler or rad is to have an inlet of around 1/4 of the size of the area needing to be cooled,after the air enters the smaller aperture the air then slows through the rad or intercooler which allows it time to remove the heat more effectively,and also maintains flow through the rad or intercooler rather than trying to escape from other places.
Ducting is essential for this,as is often moving the rad and cooler back a little from the front nose aperture.

Cheers. Yea V-mounts are good, Very good.

If theres one thing I dont have a problem with, its air temp...on the track its around 20 - 22c haaa the beauty of water injection.

Dr Rotor, What RPM are you running the engine at?

Well my setup is way off with the sizeing you are talking about...I have a huge intake hole. LOL my car eats small children.

8000rpm...every gear.

We run GT35r\'s on out V mounts.
T78\'s too!
Biggest turbo we have run on the 13b on the road is a GT42r so far,but have been experimenting bigger on other engines with the GT47.

Shouldn\'t be the pulley kit then at that RPM.

Yea more likely my ducting to the oil coolers...or lack of...hahaha.

V-mount looks good & I know my FMIC can be fliped upside down & sloted in as V-mount...but its my Rad that might not work.

Where dose the air from the rad go in a V setup? Also can the IC be mounted near on flat?

Carl · August 12, 2008, 11:16:19 PM

This is our V mount,one on stock elbow,the other on Greddy elbow.
You can see it is horizontal,with cool air feed to turbo.

Whats the highest power figure you have achived on a GT35R setup with those V setups? What dyno?

Dr-Rotor · August 12, 2008, 11:20:11 PM

Nice setups Carl....very nice.

Carl · August 12, 2008, 11:21:37 PM

Around 450hp on Dastek dyno.
Lowish boost though.
