Thread: Intake manifold options

Wont work well on N/A.

Hypertune IM looks really great!

Got some numbers on one of mine finally.



@vqman car

Nice gains on the center fed manifold! Does this use a Q45 TB? 3 or 3.5" piping? This is over a stock IM and TB correct?

Did you ever get to test out your side entery manifold?

Still working on the side fed results. We have a in house dyno now as well, so I'll be able to get some before and afters for you guys. This is the center fed with cobra TB. It's a 3" intake that steps up to the 4.5" oval TB.

Chart shows the first and last run. First run was on the same manifold before the tune was worked out.

So this dyno sheet is untuned VS tuned? Do you have a old VS new intake manifold dyno sheet?

I'm sure there are plenty of sheets around here from guys with N1's on a factory intake.

180whp was on stock I/m with n1s or stock cams?

180 WHP was done on Kentucky's intake manifold with N1 cams and a tune to make the car safe and drive-able to the Ohio Convention. Then Jamie tuned it, cleaned it up and that is the difference between those two graphs. The engine sounded good on the dyno for the base runs but as soon as Jamie started slapping keys on the dyno, the engine only sounded better from there on out.

it has been a while since i've been on the forums.. VVL is now kicking in at 5600 rpm, where it was at 5000 on the safe tune.

@nsusammyeb- i think maybe we could use 4" intake piping and have it "sweep" more instead of what it has now..

Payu has said that with the Q45 TB a 3.5" intake piping is best, based on his test results.

I would be interested in testing a long tapered intake tube.
