i have an 85 T/A 305 with hooker catback ported plenum and cone air filter and run a 15.0 at 91mph with a 2.1 60ft but with the 75 shot of nitrous i run a 13.7 at 103mph with a 2.1 60 ft and i was thinking about buying a procharger with the 2 core intercooler the p1sc i think thats what it is. and getting bigger fuel injectors. what do u think i will run without the nitrous and just the supercharger. i was also thinking about buying the gm vortech heads and base manifold and of course drag radials and exhaust cut out. what kind of times will i see with this set up?

 

I read somewhere on their site that their superchargers on a stock TPI runs 11s

 

maybe a race kit would for a pass or two

 

What kind of supercharger do you have on your project car B4C?
What kind of power increase did you see and how much money was spent?

thanks man
(i was looking for a supercharger kit for my car that i could install for more power)

 

Wrong. I got the D-1SC w/ the 3 core intercooler and a 10#pulley. I'm in the mid twelves and make good power but not enough to hit 11's. I also got other mods like gears, cam, etc and I'm not quite there. Dont get me wrong though the power is great, i'd get the D-1SC if I were you. Everyone I've ever talked to who had the P-1SC wishes they woulda just forked over the extra cash and got the D-1SC. Good Luck

I think you can run an 11 on a D1-SC. what do they put out, 1300 CFM ? isnt that enough for nearly 700 RWHP?

 

Well of course you can do it if you up the boost to like 13psi+. You can make gobs of power with the D-1SC but on a stock car, with just the kit they give you, it aint gonna happen. You'd require a pulley swap and probabbly a cog driven or 12 rib setup to get the kind of boost necessary to hit that. 700rwhp is very doable with the D-1SC.Im not saying the D-1SC's are bad,(especially since i got one) but they wont make enough power to just hit 11's without other modifications.

 

Not only that, but even if you get the boost on a stock engine to make 400 + RWHP to go 11's, better kiss the bottom end goodby!

That is the reality I am faced with.

I got 343 RWHP on my stock bottom end 305.

I would love to get a smaller pulley and run 13 + psi boost. But I have been advised by many knowledgable people that the cast bottom end is at the limit with my current HP.

Don't forget the weak link in the chain!
