TVS2650 VS Whipple 3.0L VS 4.5L Whipple

Whatís everybody maxing these chargers out at??

Any numbers on the 3.0L Whipple? I see a handful of LT guys making 1000whp with the 2650. Thatís our goal here, feeding E85 to an LSX 427, paired with Texas Speed LS7 heads, and a healthy cam. Or, should I opt to a 4.5L Whipple front feed? Not concerned about hood clearance, will cross that road when we get there with 4-7Ē Sunoco hood, or whatever our imagination dreams of at that point. ALSO, where is Whipple at with the 3.8L for the LS? One more, who is the man for the deals on these chargers?
Thank you for your time and input 👋🏼

God Bless America 🇺🇸

I'd be interested in folks opinions comparing the 2650 to the new crop of Whipple of superchargers as well.

There has to be several folks on here pushing 1000+rwhp with the 2650...

Whatís the secret to feedback from these folks?

If anybody is whipping up big numbers with their PD charger set up, Iíd love to hear your magic,

Thanks!

Multiple ZR1s are making 975whp+ with a 2650.

It seems those with a 2.75 upper pulley are making the 975ish numbers. 2.625 pulley are making 1020-1040ish and those with a 2.4 are making 1060ish and up. Those numbers are dyno dependent obviously.

Nice!! Could you lay out details?

How many cubes out of the shortblock, style head, how many lbs of boost? On E or race gas? Auto or manual?

Thank you!!!

Dart next LS 388 ci iron block. Forged rods and pistons. Solid lifter cam. 16 lbs of boost, only on the medium pulley. Ported LSA heads. ID1700s, triple Fores. This dyno run was made on E85 race fuel I believe.
