Meant to type 437..
Maybe the car would have pulled better than 411 with a bit more driving time for ecu?
Big differences....

M3EvoBR

different days, at different corrections of humidity and temps ... no miracle.

M3EvoBR

only fact that matters is same day, same conditions, same correction factors, and the delta of before and after.

Eddie, what is the usual loss of hp from crank to the wheels? Wonder what the loss is with PDK and if its different than a manual?

M3EvoBR

really hard to tell ... it's something that I never found a right number. every car is different, yu have to take tires, wheels, bearings, transmission etc in consideration.
General numbers are about 10-12% for a front engine front wheel drive
15% front engine rear wheel
20% awd

Dyno is a great tool to measure delta, absolute numbers are really hard to obtain accurately.
A good thing about the dynojet is that there is no fabrication of numbers like Mustang and other dynos.
You have the correction factors that are constant, and that's it.

Anyone scaled one of these bad boys yet? What do they weigh in the real world (not Porsche's liar weights).

M3EvoBR

sure, every time they are aligned they go thru the scales. I don't believe Peter weighted the 4.0 yet. They are all close to 3050-3100 give of take.

I drove both:
4.0 side muffler delete and M&M.
3.8 oem side mufflers with Sharky unplugged.

The 3.8 barks quit a bit louder then the M&M. You clearly hear it at startup and stays louder all the way up.
Just about as loud at highways speeds with windows closed little throttle.

I am at 3107lb with BBS wheels, LiOn Bat, 1/2 cage, no fuel. I thought that was heavy. I also have radio delete, and side muffler delete.

Izzone

its not heavy

but RA1 are very heavy

That looks about right for a car on iron brakes. US spec doesn't get the polycarbonate rear window and has extra junk in the rear bumpers adding up to at least 20 pounds.

FWIW I'm at 3,046. Empty tank, champion RS20's, R6's, side muffler delete, Li-Ion battery, OEM Clubsport extinguisher (that thing weighs some 15 pounds...)

Izzone

and we get air bags in seats.....do you?

CRex

Same same. We're spec'd with Sports Buckets (the GT2/folding type). Comes with side airbags in both the seats and the door cards. They're not that weighty though--about 3-5 pounds each from feel-of-hand.

Holy ****, who's that?
