Hey guys,

I'd run my car on dyno last friday... unfortunatly that dyno wasn't able to boost my car more than 0.9 bar ... don't know why... it actualy does, boosts at 1.2 bar on the road??? Anyway, I loved the result because it means that the 400+ HP and 650+ Nm claimed by Jarmo at 1.2 bar are forsure there... [6]

BTW, love the way the sheet looks like






Regards, Afshin.

Very nice numbers Afshin
That is a 40% increase in Torque over stock NOT counting the loss of from engine to wheels.
Hope you have some serious snow tires!!!!

321.6 US HP and 392.26 Lb/Ft are some FUN numbers. Very reliable at that state of tune also. And you have the right clutch to move that power to the rear wheels instead of burning the disc. As mentioned those are RW numbers not the raw numbers. Nice!!

Nice Afshin! I guess we'll have to get some sort of max power/torque competition going here. :)

Probably couldn't hit 1.2 on the dyno as it's not loaded. That output looks good for a mid to low 13 second run in the 1/4 mile here.

Is this with a free flow exhaust or stock? What about the cylinder head/cam?

Thanks! [bb]

Looks like if the dyno was loaded and you got it to 1.2bar (~17.6psi) versus the 0.9bar (13.2psi), output would be around 380rwhp/470rwtq. This is after some math and past dyno sheets posted on here.

Excellent digits if on stock head/cam!

ALSO - what was the Air/Fuel ratio on these runs?

The air / fuel ratio was in mid-range rich on Halmeter AF30 monitor.
Exhaust line is still OEM unless that I've replaced the middle muffler by straight twin pipes. Cylinder head & cam are also OEM ... only the gasket is from E34 Alpina B10 Bi-Turbo

Yupp Keith the Spec hybrid stage 2/3 clutch is awesome... I highly recommand that to every 745i 5-Speeder out there... [4]

How does the clutch feel? Normal pedal pressure? Not grabby?

I have the Sachs Sport clutch on the G280 but may switch to the Spec. The clutch works well but is a little grabby and a little stiff. I certainly don't have as much torque but like to have a strong clutch because of my lousy downshifting on the track...[(22]
