Super Charged W/ Stock Internals.

Dawgfude03GT · August 13th, 2007, 10:29 AM

If I ran a supercharger on stock internals how many PSI could I safley run without damaging my 281 V8? If I wanted to run like 5-7 PSI what mods would I need to look into? I am pretty new to the whole mod scene and not too sure about performance mods what my car can and cant handle. Any input/feedback would help! Thanks guys!

fuel mods

injectors... pump.. ect..

a tune

and you can run 9psi on a stock block if your tune is good.

Mine occasionally gets up to 12 psi and haven't had a problem... Just keep the car lower then 450 rwhp

Dawgfude03GT · August 13th, 2007, 11:36 AM

so if I wanna build up to run say 9 PSI what should I get first. What would you recommend? I normally use my car everyday but if I super charge it i'd prolly make it a weekend car.

your going to need a new fuel pump...
your going to need new fuel injectors
and your going to need a professional dyno tune.

I would also invest in a set of gears for your rear end and some suspension mods to handle the extra power.

Sounds good dude. Thanks for the info. How much you think that would cost? Suggestions on brands? I definitely wanna change out the intake plenum what suggestions do you have for that? Would you recommend getting an entire intake manifold or just the upper plenum? I heard the 4.10 gears are a good choice. Do you agree?

votech or paxton supercharger

HMUSN · August 13th, 2007, 12:36 PM

4:10's are ok with a sc car.

I would get 3:73's though.

I would just get the KB supercharger kit.. it comes with everything your need.. manifold..maf..injectors..ect

I was looking at the Paxton but not set on it. Just looking for now. I think I got alot more to do before I throw one on.

HMUSN · August 13th, 2007, 01:31 PM

why not a twin screw?

I just checked out kenne bell website and thats a bad ass system. Does it come with everything or would I have to choose the options? you think the gears you recommended would be ideal for this setup? I could run up to 9 PSI? That seems reasonable price. roughly 5G.

HMUSN · August 13th, 2007, 02:05 PM

the KB comes with everything you would need.

it's a twin screw so you would get instant 9psi off the line

I would use the 3:73's with it

ok so your new to modding and you want to jump straight into to complex power adders why not start smaller and work your way up before you get in way over your head

Well I am not going to slap on a supercharger right away I want to build up to it first. I just wanna set a goal of what I want my end product to be. That way I can slowly build up to it and when I get there I will know what I am doing. Any suggestions?

HMUSN · August 13th, 2007, 03:36 PM

brakes and suspension.

Blackblurr_00GT · August 13th, 2007, 08:52 PM

yes for the love god plz do suspension first b/f you do the blower cause its no fun to just sit there spin everytime you get on it ya its fun sometimes but then your buying tires every week.

Dennis · August 13th, 2007, 10:36 PM

i say if your intention is to blow it start from the ground up and do forged internals and do it all right the first time so you dont waste your money and regret it in the long run
