You can make the same peak power with a much smaller cam. With the smaller cam, you'll make more power on the low end too. No way should a cam only car pull harder than yours on the bottom end.

Yep, boost level doesn't determine your fuel needs. Power production does. If your power goes up, your fuel needs go up too. No matter the boost level.

I wonder if the 6l80's in the trucks are vastly different than the Vette versions. In the Vette, the 6L80's shoot craps at anything much over stock power levels. Making hard shifts behind a stout...

Is there any way to check for restriction between the throttle body and the blower on the EForce? IE, is there a vacuum port there? If there's no vacuum at WOT there, there's no restriction there,...

He has a bigger blower and is moving more air. His 4" pulley would be the equivalent of you running a 3.17" pulley. His 3.75" would = your 2.97. His boost might be a little lower than what I would...

If a force inducted motor does go boom, it's not the blower's fault. Plain and simple.

Average duration minus (2 X LSA). In your case 227+243/2=235....235-(116X2)=3. Your cam has 3 degrees of overlap. The "positive overlap cams bleed boost" thinking is WAY overdone.

I have no dog in this fight, but I would think that the blower would nearly always be cooler than the motor. With the intercooler system, it has below engine temp coolant circulating through it. Yes,...

I think an SLP blower is short a couple of pulleys behind the blower. Might make overdriving it a bit difficult. Try a 3.2 with the shortest Gatorback belt that will fit. Add a little alky and enjoy!...

Agree with Slickas. You're suffering from big time belt slip. I'd stick with something like a 3.4" pulley until you add the o/d rear pulleys. You might want to strongly consider a blower cam...

It looks like it was run without oil in the crankcase. Someone started it up, it made noise, and they shut it down. Damage done.

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