intake manifold .

Here are the 'interpolated' figures on the HKS vs the recently posted Indy V2. Although the weather is warmer now and conditions change, the V2 did very, very well in the comparison: (Hope they're accurate, I had several interruptions)
ADDED: The Indy V2 was with clutch slipping also.

It's being finished as we speak. I'm going to be stopping off in Indianapolis on my way to Ohio and I'll pick it up there, along with other goodies. Dynoing will be hopefully a week or so after I get there. Wilson is really pulling out the stops for the Green/Indy Manifold Racing combination. The difference will be for racing Vs. the V0/Green for the Street Manifold.

I'm sorry I can't read through your sarcasm. SloRice life is too short and I'm 1000% certain if you and I met we'd get along just fine.
As for the throttle bodies... it seems there is good evidence 2.5" to 3" makes a significant difference. Who knows about 2.5" -> 3.5"... it costs me a couple hundred bucks to try (reducer and TB) so we will see.
HKS made a good inlet manifold.. they made it for q45 throttle body. Seems they thought 3.5" would work well. Who knows though.

I wish I could do a comparison test. Unfortunately the first thing I'll be trying is the Kansai with the Q45 throttle body.
I went for the HKS because of what buschur had to say...hell I even ordered mine from him.
I have no doubt that if he recommended it, it's gonna make some great power.
Really and truly I would love to have had the JUN intake manifold. Those UK guys use it and they make some good power!!!!

11secEVO7, yes, we still have the Kansai with the Q45 on our black drag EVO.
A lot has changed since February and much of this testing has continued fairly steadily from then. My 2nd round of testing by changing up to the 3" throttle bodies was all done together and it was found then that the DI intake made great power when it had a 3" throttle body. This intake stayed on and was what I have based everything on since then. Remember though the HKS Kansai was never tested with a 3" throttle body on it. I also agree the power on the Kansai could end up being better than everything else with a 3" or larger throttle body.
The problem with the Kansai is it will NOT work with ABS, upper i/c pipe needs changed, no IAC. Not a problem for a race car, hell it's not a problem for me either BUT since I didn't test it with a 3" TB I can't say for sure what the outcome would be. I can speculate like everyone else.

I think that should be the basis when ordering these manifolds.
For me...I'm not gonna drive my car everyday...so not having the IAC etc wouldn't bother me...It actually doesn't affect my ABS...Guess it's since I'm RHD.
