Anyone running a supercharged V6? I'm thinking about stepping out of the V8 box and building a Formula parts car I have into a auto-x/road course car and running a supercharged V6. I know there are some S/Ced 3.8s in Grand Prix and Grand Ams that are making some real power. Any advice?

 

Spend the money on something else. Nothing against 2.8's and 3.1's but they make better daily drivers then performance engines.

 

I wasn't considering a 2.8 or 3.1. I was considering a 3.8 or 4.3.

 

I'd still say spend the money on something else. I'm not saying it couldn't be done, I'm just saying there are easier and less expensive ways to go fast.

 

Whipple used to make a s/c for the 4.3, last time I saw one was about 10yrs ago. It was a small roots blower that went under/replaced your intake manifold(for the tbi's). Unsure if they are even available anymore now that turbos seem to be more popular.

 

For 3.8 turbo advice, I would go to a grand national board.

For 3800 s/c advice, try clubgp.com

For 4.3 advice, Id go to an s10 board. I know they do make a s/c for it, in fact it might be the same one as a v8, just with a different pully.

 

as I've tried to convinve many over @ fv6/cv6 l67 short block, f-bod heads & intakes, turbo. that way you don't have to worry about firewall/tb clearence, and the rotating assembly is already prepped for forced induction.

When I get get my own place I'm gonna see about doing that, or whatever new v6 ittereation i cain get & do another engien swap.

 

Thanks guys. I'll look into those sites.
I'll already have a fast V8 car when I start on this. A friend and I are going to build the Formula as a project.
I think I may go with a supercharged engine. I've heard that when a turbo spools, it can create more tire shock than N/A or a S/C, which wouldn't be good in a turn or on a auto-x.

 

there are s/c kits for teh 4th gen cars, powerdyne & rk sport.... but not realy that cheap, unless yo cainpeice a kit together, or catch one for sale

 

Had another thought you can use the paxton centrifical s/c, the kind you mout like an alternator that uses a v-belt to run off your crank pulley. You'll have to fab the brackets and possibly a pulley to make it work on the 60deg V6. If you go with the 4.3, it should bolt up (providing you buy one for the same year V8.)

 

The problem with the 4.3 is that they're garbage. They tend to drop valves, eat bearings, etc... The 3.8 is another animal, but for the amount of fabrication there are countless other projects that would be more rewarding and easier. Not to mention that a 4.3 or 3.8 doesn't weigh that much less then a V8.

I'll never understand the appeal of busting ones hump to build something unique.

 

what's te weight diff between a sbc &an ellis juan? and the 3800 weighs less than both.

 

My last 4.3 went over 298,000mi and if I didn't keep driving when I saw the trail of oil...
I've had two 3.8's that barely went over 100,000 before the bearings spun (with reg oil changes).
If your not busting his hump, are you just trying to convince him to swap for a V8?

 

For some reason.... I don't think that the 4.3s are garbage. They are pretty reliable and can make good power. They are quiet literally a 350 with two cylinders chopped off. GM is still using them after all
