Suggestions about Header size.

I skipped the single turbo plan. Got real good prices on Vortech Kit. Going with an V7 Ysi trim instead.

So whats about superchargers and exhaust size. around 1000hp with n2o. 850 on motor. 7500rpm. 4500rpm stall.

Is a 2-1/4 with 4" collector the way?

Larger?

You are a maniac! And I mean that with the utmost of respect! graemlins/thumbsup.gif

why no turbo? it will make more,
more efficient power

Yes, it will. Mayby.

But with that prices i got. And those turbo deals.

I got sponsor money covering up the whole system. But no money on turbo setup.

So getting new EFI ECU, Broadband lamda and a superchager complete for some Vinyl.

Or pay mayby 4000$ to complete install. I weighted in cost because i should only be doing 850hp. And both ways can do it on a miss...

Larger? 500HP and < use 1 5/8"
525 - 625HP use 1 3/4"
625 - 700HP use 1 7/8"
700 - 775HP use 2"
775 - 850HP use 2 1/8"
850 - 925HP use 2 1/4"
925 - 1000HP use 2 3/8"

Where did you get those numbers from?
