Get forced induction. That's where it spawned from, high altitudes and engines starving for air. Mind you, this was in planes, not cars, but us crazy people always find a way to get one thing working for another

I have never seen a dyno not use the front cooling fan, on LT1 or not. Loading the engine without cooling it like it would be naturally doesnt seem like a good idea to me - I sure wouldnt let them do it with my car.

Placing a large fan blowing cooler denser air into the intake tract can often lead to misleading dyno results. I try to eliminate every variable that I can. Maybe that's why I don't get those great dyno numbers that I always read on here?

Like I said, I would assume they use that not just for cooling purposes, but for simulation purposes as well. If I was you, I'd run 2 with and 2 with out. Both after the car is up to operating temp.

but heres some number for ya
cat back exhaust, cat delete,stock exhaust manifolds,2800 stall with stock 2.73 gears, full weight on 17" ss wheels/nittos
12.92@105.9. That was my car and those were my mods just because you drop $400 on a pointless T/B and some injectors dosent mean you going to go fast. I put a 52mm T/B on after those mods and didnt pick up a .5mph or a even .1, as a matter of fact it did absolutly nothing.
Judging by his mods 1.6 roller rockers would be money much better spent
