How much gains are decent? Peak or under the curve?

Peak. With the other dynos I've seen, the other manifolds make great power under the curve but loss a lot up top.

I am making the runners a tad longer which should help midrange torque, which is all that can really be done for the NA... I dont know that there is much to gain on the top end in intake manifolds without spinning the engine much higher.

That's what i figured. When do you think the launch date will be?

I am not sure yet when they will be ready to go. Once production begins, it will go very quickly. But it hasnt begun yet.

Charles can you please include me in on this! I can add this to the two test Ive done with the Z1 and the M370. I still have a ported M370 that I'm debating on putting on the car or selling. :/

Yes please.

don't know how i missed this... sub'd

So maybe you could contact Sam from gtm and have 1slow370z prototype fitted to a car to test your manifold on a well suited na Z? This is what a community does.

I'd be onboard for a IM that made substantially more torque off the line (say, 15 - 20 wtq) even if top end was unchanged.

That might be wishful thinking tho'...

Can you post the test results for the Z1 and M370?

He has a thread in this forum about 6 pages long with all 3. He chose the Z1 mani and sold his ported M370 and regular M370.

Here you go http://www.the370z.com/intake-exhaus...d-testing.html

I like what the future holds. GTM, Doran, and CJM all have intake manifolds in the works. Let's get them released!

Thanx man! :) not entirly true tho, I still have the ported M370 and another regular one . The ported one I decided to keep. LOL I'm thinking of putting the ported one the car after the 6th of June, Dyno with Z1 and ported lower.

The only hope on that list is CJM. GTM will never release theirs and if they do they going to have to give them away for what they did to people :icon14:
