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

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.

443whp dyno thread

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?

Self tuned or did Hans do it?

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

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

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

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

lol duh look at the graph...

Progressive aem controller starts at ~12

great numbers! :)

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

yeah maybe. would just be interesting to compare how much of a restriction the flow of the evo maf really is at that power level.

I'd guess probably 15-30whp...

It's possible it won't affect max HP but the power getting there.

OK, time to put the gm maf in mine after breakin. What are the differences between MAFT GEN2, and MAFT PRO, and will the pro work?

MAFT gen II is a complete tuning afc. Pro will let you do speed density. I only used the gen II because that is what I originally tuned with. Just go with an original MAFT because all you need is the translation. That is, if you go with it.

I picked up the pro used, and new Gm Maf. Just one more thing to research! :P

All of the locals think my dyno reads low.

Stock heads?
Stock cams?
Stock cam gears?
fmic?
stock drive shaft?

great numbers and sweet car!

Stock heads
Stock cams
Stock cam gears
IPS FMIC
PTS AL driveshaft

Thanks!

Car looks and sounds great! Congrats:stewie::ghostride:

Thats really impressive, are you using stock pistons and rods?

Toni is on forged pistons with stock rods (from what I recall).

Very nice numbers!

You start to see a vacuum inside the intake tubes at this power level with the EVO MAF.

Maybe I should move to it so I can actually get a vacuum under my BOV to help hold it closed :rolf:

It would pull it open...

Hey can you post a shot of your timing map?

Not the normal boost/vac line. The lower nipple of the greddy... It was mostly a joke though lol.
