bravo 35 Report post Posted April 17, 2007 >As you see, at no point did the post curve dip under the pre curve and also >that the most notable gains were up to about 4400 rpms. ( also the worthless >gains above 5500 rpms ). Worthless gains above 5500?? (the words "agent provocateur" comes to mind!) Post the numbers above 6000, wouldja... Because those "worthless gains" will save significant time off your 0-60... On a BMW, the revs above 5500 aren't there to LOOK AT.. they are there to DRIVE..every day.. Try this: 1st.. redline.. 2nd.. redline.. 3rd.. Then get back to us.... Jim C. nice. Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted August 31, 2007 A new sticky thread. Post up your engine power/torque [measured at the wheels] and 1/4 mile times. Must be accompanied with Dyno graph and drag slip times. Please convert to kW and trap times to kph List will constantly be updated. Right now i'm just going off the top of my head on some powers so we will correct the list as it gets updated by members. Darren [sR20DET] - E30/240 kW (?) 1/4 ET: (?)

BM WORLD 1283 Report post Posted September 1, 2007 A new diff won't get you more powergavin wreckons different results , like changing wheels etc higher gearing is like turning bigger/heavier wheels etc .same power at flywheel but different results measured at the wheels .

Mike 1 Report post Posted September 2, 2007 I really can't see how it will change. horsepower is torque x rpm. as you know changing a diff will change torque to the wheels, but will also change rpm accordingly and should result in the same power, The same should also be true for the torque if you run in a 1:1 gear and account for the diff ratio each time.

My e30 at the moment running 12psi at a 65% tune is putting out 270hp at the wheels and has done a 13.42 at night speed on all 4 chromes. was doing 174.something km/h at the speed trap. still in need of retune at higher boost etc but not bad for now.

cainchapman 0 Report post Posted January 3, 2008 (edited) Well, I was referring to BMW powered cars Riley, and yours has an estimate of power at the Flywheel, whereas mine is at the wheels. The 540 is 214kW at the flywheel, so I win on that basis still (compared to your beast). I'll look forward to the 1/4 mile time. You'll have to get it around Ruapuna and compare lap-times. The 540 has done a 1 minute 53 second time. (full track, excluding dipper) Edited January 3, 2008 by Cain Quote Share this post Link to post Share on other sites

(full track, excluding dipper) no no mine is 279.1hp/208kw at the wheels, i thought it was at the fly but its not.dynapac dyno i was very suprised to dont worry. So mines more like 250kw at the fly est.

cainchapman 0 Report post Posted January 4, 2008 Getting another 30kW out of the 4 litre might be a bit of a stretch for me. I guess 210kW at the wheels in my new target then.
