Makes tons of power on a fully tuned, ultra highly sprung NA application. I think their released figure was in the upper 400's at the crank (460-480).

Did you include velocity stacks in your's?

 

Yes

 

Cool, I take it back. Looks efficient, now the real test: Flowbench, dyno, or both.

P.S.

Did you take measurements of the runner lenths and diameters stock and modified?

 

Direct port is about finished. This will be an option when selling the manifold.

 

looking good man

 

still in for results

 

bump for results too

 

Did you ever get a chance to dyno this yet?

 

+1 forgot about this.

 

So hot...

If you can show dyno gains (without the typical tuner BS), etc., then a lot of people will be interested.

Bump for the OP.

 

Thanks for the bump. Still in process.

 

I would like to see someone make a manifold like they have on LSX engines. Maybe make a wire harness to extend the drive by wire setup and TB to the front and even make a nice cover for the top to cover the wiring as it goes over the top. I think there is a lot of power potential in the manifold b/c the factory design has that bend in the neck. If air just went straight in, I think it would help a lot.

I'm still anxious to see the results of this but with the bend, I think there will still be room for improvement.

 

Can't do that to our car like the lsx.
Our bonnet is to low and we have the timing chain cover in the way

 

Making power, especially to redline, seems to be held in the plenum volume. Increasing the volume from the TB to the heads is where you'll find effective gains. If this plenum has increased volume in that area, it will make high RPM power. If it doesn't, my bet is that it will be comparable to current manifold options. If the runners are longer than stock and the volume is smaller than stock, expect to see losses and peak power being made below 6250rpm. I'm curious to know how much R&D was done with these key points in mind.

 

Wrong.

wow looks sick with all the nitrous hardlines.

 

That's nothing like the ls series manifolds that enter in the front in the middle like what was talked about

 

think he meant this.

 

Steve-o ment the log manifolds that sit inside of the valley and go forwards where our timing chain is
