Nothing from racer x either. F.i. is the only way to go with these things.

RacerX has teased some recent photos on FB(1-12) of their new manifold but it is not ITB.

When will peeps ever understand....lol. The only solution to these is the revolution dual ram intake with bigger throttle body. Much cheaper and similar results.

It would be great if you stopped spamming this thread with that suggestion.
Especially since the manifold is a known bottle neck with these motors. You know what hasn't ever come up as a bottle neck? The intake and throttle body. You're basing this on one dyno test with this intake, and they were hardly concrete/conclusive.

Just let the results come out from a reputable source regarding the ITB's, if they're still a major loss than by all means you can continue venerating the revolution intake.

The only bottleneck is the header. Speaking n.a. of course. Some real intelligence went into the intake design.

Why can't we have both Better intake Manifold with bigger throttle body and revolution intake?
Tune is big concern that someone works side by side hardware/tune to make it work right. Like ACE/Delicious/CSG all worked together on make the headers work


I think with the Intake Manifold tuned the front of the intake might not matter as much. Kind of like a Catback exhaust doesn't do much after the ACE headers.

They are on their second prototype and they plan on doing 4 total. RnD takes time, its not like its the only thing they have going on.

so... is this just another hype thread?

I wouldn't say hype. The results were probably poor.

No, it is not a hype thread. We spent a lot of time on this setup dialing it in for a completely stock vehicle. What we found was the power/torque gains are all in the middle of the power band and the top end is the same. No do realize this is on a 100% stock car otherwise, running 91 octane.

The next step is to get some headers on the vehicle and see what it can do. Also working with an engine builder on some suggestions he has to make the ITB's really do their magic.

Were the gains noticeable and repeatable, or anecdotal?

Nothing wrong with more midrange.

One would argue that additional mid-range power on this engine would be welcomed. Were gains substantial?

truth is, the only reason i want to do ITB is for the sound.

as long as it has that, i'll be happy.
