482whp on b-dr650s chromed flash ecu 50/50 meth @GZP dyno

[Toni]

Stuck on some billet dr650s (original clipped hl wheel) and went for some more dyno pulls at Ground Zero Performance. Ended up with 482whp and 470 ft lbs @ 21/22 psi. Spraying ~700cc of 50/50 water meth and 93 pump. We had problems with my Greddy type s holding. It would flutter open here and there otherwise we were going to try colder race plugs and more boost. Will have to fix and revisit.

BTW: Last year I ran an 11.67@121.6 with a 1.7860ft. Found out I had a busted vcu. Should be better this year!

Other run on here are my td04L 15gs @ 20/21psi.

New changes:
billet dr650s
12psi wg springs
Pulled a couple deg of timing. No other tune changes.
Sprayed meth earlier but progressively,Start @12 full flow at the same boost of 16psi.

Nice results!

Congrats. Very cool stealth you got there. I like all the mods.

Are you using GM maf with flashed ecu or evo maf?

[ICPREY]

Self tuned or did Hans do it?

GM 3.5 maf with maf-gen II (not maft original or maft pro)

Self tuned or did Hans do it?

Tuned by Greg, Hans, then me in the order of most work on it.

[Ange]

would be cool to see if you could squeeze out the same result with evo maf

What dyno, Dynojet? Where are you starting to spray?

[CoopKill]

lol duh look at the graph...

[Toni]

What dyno, Dynojet? Where are you starting to spray?

Progressive aem controller starts at ~12

[NOMIEZVR4]

great numbers!

That number is very doable with an EVO maf but probably much easier done with the GM setup
