Numbers still seem really low to me...anyone else think so? Or am I just ignorant on the LT4s?

Looks like the torque curve was adjusted but not much else. Bets on how long before this guy burns up his stock supercharger with those pulleys?

Sounds like he got this:

That's awesome!! I can tell you are really enjoying that car. That's what counts!!

That's about how the LT4 reacts to pulleys. Remember the LT4's 1.7L blower is already "Pulleyed" from the start, there's not a ton of room left on the table for supercharger RPM. But there is much gain to be had from porting the said blower and adding E85 50/50 mix and a pulley/exhaust/intake, nearly 700 RWHP worth of it.

Yes, that's correct.

You do the math.

I hate to point out the obvious but there's no math to be had; there's no baseline.

Seeing the graph on its own, it's very nice. It's probably a righteous rocket.

People use various means to come up with the HP from the RWHP. I've had guys say 750 some say 725 etc.
Don't know for sure but yes sir it's very fast.
