turbo probably won't do much to the rpm range. a cam will help with that.
THEN the turbo :D

The LS6 actually has a really good rev range. I know peak horsepower on the LS2 engines is at 6000 and 6300 on the LS7.

i thought one good thing about the v8 swap was you don't have to spin them very fast to make power. if you like turning 7-8k, stick with the rotary. it'll at least live at those rpm ranges happily.

I don't like the turbo with the Renesis.
I don't believe they have reliability. I belive Pettit Racing.
Look we already have blown Greddy turbo's.
Great job on the tume Scott.
I''m waiting for linear power and reliability with a Super Charger.
I've already passed Turbo's on the track during the hot summer due to heat soak.
Then when it's cool I loose out to the same drivers and cars with the turbo's.
Super Charger here we come!

define "fast" 7k is rediculously fast for a big block.
8k isn't even redline for the renny or s2k motors.

Heat soak? On a car that is moving?
You need to do a little more reading before you consider anything.

I probably haven't done enough research on that, but is anyone doing DI on anything other than 4 cylinders yet (non diesel of course)?
Whoops.. we're back off topic..
I'd love to hear from scott on this one too.. 5psi/300hp would be totally awesome for this motor..

Perhaps this is a fundamental question, but where is boost measured? Generally speaking, a NA engine runs with a negative gauge pressure in the IM. I don't have a good value to estimate how much vacuum a WOT Ren generates at 7-8k rpm. Is boost measured directly after the compressor? How would that compare to a MAP sensor reading? And in a 5psi boost application, where is it 5 psi gauge?

[QUOTE=MazdaManiac]No, its still on.
400 RWHP at 15 PSI? That is a PR of over 2.
What is the typical RWHP number on an FD at its stated 255 engine HP?
Do the math! You are still in fantasy land if you think an FD is going to put down 300 RWHP at a PR of 1.3. Hell, its OEM tuning is hotter than that and the RWHP is barely 2/3 of this claim.
I ride around in a FD that puts down over 300rwhp on a regular basis bro. And it is set up under 14psi.
Second note. I don't think that you have realized or atleast noted that other modifications have been made to Scott's test car. I know that n/a mods are small but Scott has gotten well over 200 rwhp on an n/a 8. So begin your scientific brake down from 200-210 not 180....big difference.
Edit: Yeah I know I jacked up the quote boxes.......

It has already applied GDI in different engines, from 1.5-litre four to 4.5-litre V8. Now most of its production engines are GDI-equipped.
