Flipside Intake Manifold and matching throttle body q45
This will only work with 99 or newer heads.
Custom Flipside intake manifold for sale.
I never used it because I decided to go V8, bought it like it sits from another member here. Comes with some bungs that need to be welded.
It looks very beefy and well made, set up to work with a Q45 throttle body.
The runners are a work of CNC art!!!
This manifold is for those who want to make a lot of power, you do not need this for 300whp goals.
You will need to modify the alternator bracket to make this work.
$350, negotiable on the shipping.

It is a VERY nice part though, and worth every penny. GLWS

100% correct, this is for top end gain.
My intentions were to modify it by making the runners longer and curve, just like JayL had in mind.
But going V8 changed my plans just a little bit.
Had I done that, this would be the nicest IM out there.

There is not a direct relationship between runner length and rpm.
Longer runners will have a strong resonance at a few RPM ranges, shorter runners will have a weaker resonance at a larger number of RPM ranges. So with something like this you would lose the torque "lump" created by the super long runners of the stock manifold, but should gain everywhere else and on up to high rpm where the stock manifold is choked.
I have seen where going to a shorter runner manifold created a gain not only at high rpm, but also at low rpm. With some loss in mid range.
If I still had a miata Id be all over this.

Reality is most people on here are fine with the OEM manifold, those who are breaking over 300whp are at the limits of the stocker but still fine, if you want anything more, then you really need to look at a different manifold. As far as manifolds go, this one here is just an ***-raping beast!
