whats the difference in front mount and v mount it?

V mounts are at an angle so air can flow to both radiator and intercooler at the same time. Neither get a completely direct shot, but neither get neglected either.

Cooling
BrasilianRx8_2 I'm sadly not an owner of an RX8, but I stumbled accross this site in looking up information for a friend of mine (Whom I'm trying to persuade to buy an RX8!!!). I noticed your cooling issue, and I wanted to throw my .02 cents in. I'm no mechanic, but I tinker on my hobby car with the help of a friend that's big into speed
I've got my Eclipse just over 500hp, and with some more aggressive cams, and a little more boost, I hope to touch 550hp this season. My car has a twin Eclipse, same color, trim, everything, that put down an 11.74 - 1/4 mile last year. So its my turn this season! Anyways, I tell you that to build my background. I only scanned through this thread, so if any of this is wrong, or a repeat of someone else, forgive me.
Some ideas I used on controlling my temperature:
Have you tried a full race gas to see what that does for your temps?
Have you looked into a water injection setup?
Have you checked the atmospheric temps under the hood after you get your temps up? I know a few people that saw a pretty nice drop in EGT's just by building a custom "ram-air intake" or "snorkel" from the front of the car to the air filter (and possibly the RX-8 is already built like this, I wish I knew
) So if your underhood temps are high, and your filter is just sucking that air in, up go your temps exponentially. Warmer air going into the motor = much warmer air going out, and a warmer engine. Which will in turn warm up the air even more and repeat the last part
(I assume you already knew this though).
Race gas wasn't a lot of help on my temps, but it kept me from seeing knock, which let me pull out a little more fuel (I'm using DSMLink v2 ).
However, I have a water injection setup I built to help me run 25+psi (my compression is a BIT lower than yours
). My EGTs saw a HUGE drop! I don't think I could run the FP3065 without it. I am so much more efficient than a front mount I/C!
I built my own water injection setup for ~$200USD, and at that price, its worth a try!
I just bought a 2005 Ford Powerstroke and the first thing going in is the water injection kit! I'll keep those EGTs down when I'm pulling my Eclipse to the track and home
!
Let me know if you have any questions, I'll help as much as I possibly can! I hope something in this mess of half-asleep mutter is useful to you.

I have this on my car :
http://www.designengineering.com/pro...asp?m=sc&cid=1
Sprays C02 directly onto the intercooler cooling down the intake air. Also has a device where they have a metal bulb in the pathway that can be injected with C02 lowering the intake air even further.
Also this company has various wraps for the exhaust manifold & the turbo as well. This can reduce underhood temperatures
