Before/After 93 to E85 Lund tuning Dyno.

[RomanB]

Rbs550 trapped 126 and dynoed 418 ... I've trapped more than 125 with a bad 60ft

I know that the dyno he was on was reading ridiculously low...

he had negative da on that run . i can probably run that mph in negative da also . only 1400ft difference

I know these aren't spot on, but physics is physics... And she has to be making close to or over 500rwhp

The S550 doesn't have 20% drivetrain loss. It's about 12% for manuals.

Sacramento is notoriously fast, just back those numbers and MPH up at Sonoma and I will be thoroughly impressed. I never raced at Sacramento, but have the word from a non mustang guy saying Sacramento is 3-4 fast.

The calculation is at 8% drivetrain loss. 20% would reflect 640 flywheel horsepower. 12% loss would calc 585 flywheel horsepower. I wouldn'the trust that calculator for anything :headbonk:

That explains why all the guys I beat from the Bay Area complain about how they are faster at sanoma

 

[RomanB]

how did you get down to 3750 race weight? I literally wouldn't need to pull myself out of the car

Then head down to Sonoma this weekend, should be a 10.8 @126 car there

That's ridiculous trap speed and i am a believer of a factory freak cars. Some of the engines are blessed with hp and torque fairies from the night shifts. Another car that can trap that NA if i remember right might be a c6 zo6 on a really good air with 500+ hp and 3130 lb weight.

We hardly ever have negative DA here. To put into perspective how bad our air is in summer and most of the year really I have a friend with a 2010 Camaro LS3 with a big cam, long tubes and catback exhaust. It dynoed 470whp SAE on a dynojet. He ran it a couple weeks ago at Bradenton and it ran a whopping 13.0 at 112 MPH. Now he cant drive but that trap speed is horrible for a 470whp car even if it is around 4100lbs race weight.

I think that's a good idea, at least it will shut up the non believers.

I think that run was last November

Maybe they should come run at sacramento since its a rigged track . They should have no issues beating their personal bests .

Was he living in Florida at the time? I know he moved at some point. I remember last Christmas it was 86* and pretty humid. Last winter didn't get cold until into January and February.
