I am looking into a 408 supercharged setup anyone one here got something similar. I am shooting for something around 650 hp possible? how much boost should i have to run to get near that?

thanks

 

There are a few supercharged single digit cars, couple 347s, not sure of any 402/408s. I ran 9.90s @ 3400lbs with ~550rwhp (TH400/8" converter) so it doesnt take much if the car is set up for going down a dragstrip.

 

I have a 408/D1SC setup, I haven't run in the 9's yet but have run some decent MPH for a soft launch (135). My race weight is up there too, 3900 lbs. I plan to lighten the car a little and try to crack a 9.99.

 

I got a lil 347 w/ a d1 and goin mid 9s thus far in warm temps... Should have no problem knockin off a couple tenths by the shootout/ cooler weather...

Im buildin a 402 but with a turbo/ thought about a big procharger, but i feel turbo is the way to go...

With setups identical to kp and myself - a 408 and a d1sc should see low 9s/ high 8s in good weather...

d1/t trim and a decent flowing ls1 you should have no problems hitting 9s

 

My car ran a 9.33 @ 147MPH with a Novi2000 and a forged LS2 402.
Turbo400 tranny.

 

I would think your motor is a little high on compression to be doing FI..I was thinking that Coby said it was around 12.1

 

it is 11.8 i believe....and i made this post before I had even seen his motor....I am now going to be doing nitrous due to compression and cash flow. I was thinking about the blower setup when i was going to have a motor built....so i have scratched that now

 

i have a paxton novi 2000 for sale that put out 809 rwhp on my 99 vette. head unit and pulleys on an 8 rib setup for 2500.

 

11.8 is good blown with alky
