Take it easy man.

To me it seemed like you thought his car was s/c when you posted that. Either way though, there's no need to start anything.

Neon, this is exactly my point as well.

I suggest you go back and read my reply, and maybe explain to me in a PM how I was jumping down your throat.

You will NOT post your reply to me in this topic.

Turbo would be easier to get more top end out of than a supercharger without digging into it... The smoothness of it will be "easier"on the engine as well.

Tuning an L27 for a turbo has never really been done, we've never seen it around these parts, so you better know what you're doing there... ;)

the compound induction was a suggestion, maybe you took it the wrong way.

couldn't wait to jump down somebody's throat could ya :roll:

And I just couldn't imagine if some did that to an LN3 or L27 engine and started destroying the pistons... and then it would be a complete custom tune, if you could keep the pistons together...

I agree with sandrock for many reasons.... If you are going to park an M62 Eaton on top of a 3800 Get the L67 short block at the least

Well, supercharged at 8psi, has increased the HP from 170 to 220, but with added friction, we think turbocharged is much more efficient when it comes to making power. We've thought of a supercharger, turbo setup for low end and top end, but the concern was at higher RPM's, the supercharger lobes would be a restriction for the turbo.

You have alot more to think about besides the forced induction.

Pistons, rods, and wrist pins for starters. Axles and trans soon after.

Yeah, the best thing to do is to buy a supercharged, and hollow out the supercharger, it already comes with a stronger tranny, and is built for forced induction already.

Don't go that route. You will have absolutely no torque at all. The supercharger casing, and the LIM, aren't designed to flow well at all under NA conditions. Actually, it will flow TOO well.

Going that route, you WILL need to swap in an L27 upper assembly. I'm not sure about the accessory drive...I think you might be safe there. You will also need swap in an L27 cal chip (ECM should be ok to leave in there), and tape off your BCS lead.

Ah, but a hollow SC case is a good spot to squeeze an air-to-water intercooler.
