Twins VS a Big Single??
I've seen them make alot more then that. But at those levels it better have the right internals and a good way of keeping the heads down and it'll last forever
Rotary1307cc : It's simple math really, 378 cid x 1.4 hp per cube = 529.2 hp N/A.
That's not to much to ask out of a 10:1 378 with a good set of heads with the right piston
and ring package.
AS a good rule of thumb 14.7 psi will double the N/A hp if good fuel is used.
529.2 x 2 = 1058.4
So 945 hp is about 10% less than 1058.
Give or take a little the math works the numbers are real.
If you are having trouble making power without inflating you silicone couplers
like party balloons we can help you.

lets see a vid at the track putting up a trap and log of the same run so we can view the MAP, and cross it against time to see that it really is the log of the pass

I don't know what N2OBaby considers a streetable 9-10 second car, so maybe if he defined that more clearly, it would help. My definition would be really fast WITH factory-comfort or better... so that pretty much throws out all track-oriented suspension components, eliminating A/C, and/or putting in a cage.
All I'll say is that I've never seen a 6 liter that's built for boost with 317s that made anywhere near 530 rwhp N/A nor have I ever seen a turbo kit that has been 100% efficient aka doubling power at 14.7 psi. There is no such thing as 100% efficiency, physics are a bitch.

And i guess trap doesnt tell anything about TRUE hp put down and applied
dyno numbers are the true storyWho said anything about et here??

When the motor has a ***** in N/A form it's not hard to make the #'s
with boost.
Read his thread, you won't read anywhere were he says I'm out of injector or I'm out of fuel pump or I'm out of compressor or the back pressure is to high or my vagina is itchy.
The only set back if you can call it that is wheel spin.

Verdad Gallardo Sorry I don't engage in stupid arguments such as this as you can say anything you would like to prove what is said otherwise. I think I'll stick with the physics behind it since you aren't Newton and I don't know of another who has proved him wrong.

Ya gotta think of it in terms of a single turbo with 1/2 the engine. If you look at some of the 4 bangers out there, they are making north of 700 hp at the wheels (some through all wheel drive transmissions that are every bit as capable of robbing hp as a auto) with a single billet wheel Garret 35R or Borg S366. Now apply that same logic by dividing your engine in half. 370 now becomes 2 185 CI motors or 3.0 liters. Look at what some of the import guys are able to do with 3 liters and apply it to twins. It is not exactly apples to apples, but it is close.
