9sec9 this was months apart and with a different motor I think too isn't it? And was it the same boost level even?

 

yes, the HKS was tested in February where the V2 was tested recently. Temps were 38 degrees cooler in February. Current motor is different for sure, but not sure what is different. Peak whp is very similar though.

 

9sec9,

Have you received your V2 yet and when will you dyno it? I would like to see what type of gains you pick up with it.

 

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 going to bolt the biggest turbo I can find on to my car. It's going to make more power because its bigger......

 

What on earth does that mean?

 

Seriously I don't mean to be rude, but how dense are you??

It means....just because its bigger doesn't mean its going to make more power.

 

And when did anyone talk about physical size in this thread?

 

Yup, you're dense....

65mm vs. 3.5" Q45 throttle body ring a bell???

 

My bad on the TB. The HKS was using the STOCK TB where the Indy V2 was on the 65mm TB. Still, I guess for almost $700 difference plus the TB difference, that shows how good the V2 really is.

 

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!!!!

 

I don't think anyone could question that the HKS, DI and IndyEvo V2's are all winners. After installing either of these manifolds, the tune, driver and other mods come in to play. None of these are losers in any sense of the word.

 

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.

 

Glad you mentioned that aspect.
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.
