Yup, you can cram a potatoe in an exhaust pipe and get the same effect. Even more boost and even less power.

Ummm, 15-20 degrees less than you're seeing now with just a heat exchanger swap IS pretty spectacular.

I'd concentrate more on a bigger heat exchanger, bigger coolant reservoir, and a bigger pump. Feed your intercooler more and cooler coolant. 416 if you have to, but the power gains over a 376...

Most with lower compression run more timeing. Cylinder pressure is probably similar to a higher compression motor running less timing. A bad tank of fuel can get you either way. A low compression...

"People" aren't the only ones that say it. Unless the GT9 cam is different that it used to be, it uses Comp Cams's LSK lobes. This is a quote from The 2013 Comp Cams Master Lobe Profile Catalog:

The left side of the dyno sheet does matter on a street car. I'd urge the OP to drive, or at least ride in both and decide what he likes. If he wants a very reliable, simple, safe 600rwhp, a Maggie...

With a mild blower cam, the 3.8" will get you 9 to 10psi and mid to upper 600's depending on dyno type, tune, octane of your fuel, and whether you're using meth or not. 3.6" gets you either side of...

The static compression ratio is lower. That's going to have a pretty big effect. I would imagine the dynamic c/r is lower too.

How much are the ported heads vs stockers? One good thing about the LS7 cam is that you can use stock LS3 valve springs or at least fairly cheap single springs. I'm guessing your ported heads will...

A clutch to turn the blower off and on is very doable. But why fool with it? If the blower uses little or no power when not in boost, there's no reason to add the complexity of a clutch. The clutch...

The Heartbeat is similar to the EForce as far as fitment goes. It's not anywhere near as tall as the older Maggie TVS units. It fits under a stock C6 Vette hood.
