My insurance never went up and i checked with the insurance company... I was told they don't care what HP I had... the VIN said it was a 6 cylinder and that's all they went by...

You think you are going to make the kind of power that beats V8's on your modded V6 using 87/89 octane unleaded? Good luck with that.

When will you all learn? Pay attention to the Grand National crowd. That's a 3.8L V6, making ungodly HP...look at the stats with those sixes.

The GN crowd has been worshiping the V6 for years. It's not uncommon to see 3600 lb. steel body Regals running 9's consistently. And they're always locking horns with the built V8 normally aspirated crowd.

Turbos are actually more efficient than superchargers, turbo lag notwithstanding. In fact, the fastest piston driven cars on the planet are turbocharged. Don't underestimate the V6 when the rules change...

where did the sts v6 numbers come from

Um,yeah. Happens all the time, doesn't require luck. Google Grand National sometime. Alky changed the rules, and pump gas/high boost is the norm. They beat V8's routinely.

My little V6 single-turbo Buick powered Cobra runs 11.40 ET and pretty much beats any LS motor or Ford BB I'm up against. and I get 25 MPG. Now I need to get my twin turbo Spyder to the track...

Now, when you mod the LSx motor with forced induction, well that changes things. Much respect for the LS family at that point.

I'd vote on the turbo'd V6 as a braggin' rights project. Been there, done that.

I always used the rough figure at 15hp/lb of boost. That one actually equated pretty well.

I should also add that if you are entertaining modding a V6 Camaro with the use of a turbo (or turbos), it would be beneficial to have an automatic trans to start with.

You will get better acceleration and quicker ET's with the auto trans.

It all has to do with spooling and boost; the boost hits, say, 15PSI from a launch, and STAYS there throughout the shifts. You can't do that with manual trans - you'd need to re-spool between shifts.

Pay attention to the Buick crowd. Lots of info there.

Since the V6 has base compression pretty high, you would need to limit turbo boost to say, 6 or 7 PSI. To really attain the big boost, you actually need to reduce your base cylinder compression. The 3.8L engines were around 7-1/2 to 1 base compression for the turbo applications.

The poor man's trick was to double up on the head gaskets. But the right way would be to install dished pistons to lower the base compression.

It seems the ECU has enough lee-way to get you enough fuel to suit your tastes, with a basic tune. Direct injection reduces the detonation effect so that's a plus.

Twin turbo seems a little too expensive, unless it gives results that surprise people. single turbo might be good enough.

yep... single would be fine... Twins to show off! LOL!

I don't need to Google anything, I'm well aware of what a Grand National is and what they are capable of running. See, I was actually old enough to legally drive when those cars first hit the showrooms/streets and remember well the 5.0 Mustang/GN shootouts that sprung up soon thereafter.

What I said still holds true. The fast V6 cars do NOT run 87/89 octane pump gas. Sure, they CAN run on it, but not without an alcohol assist at higher boost levels.

What does your car run garagelogic?

Don't know yet. I didn't everything installed and tuned before the local tracks closed, so now I'm just waiting until they open back up so I can get some runs in.

I'm hoping for mid-10's on the 93 octane daily-driving tune/boost level I'm running on the car right now. My last car, a KenneBell 2007 GT500, making a little less horsepower and quite a bit less torque, ran a 10.76 @ 131mph on drag radials with a 1.76 60ft time. That car, with driver, weighed 4160lbs.

I hear J Leno turbo charges his car with his big dumb chin.
