I think some guys on here might be living in higher elevation areas affecting their times and, of course, most seem to be running puny tires.
An ALPINA B6S (3.5 M30 260hp 237lb-ft 2.79 LSD 2950lbs) was capable of a 14.4 @ 97
A Hartge H35 (3.5 M30 260hp 257lb-ft) was capable of 14.7 @ 9x
so an S50 should be capable of a mid to high 13 @ ~100mph with a few weight saving strategies, a few bolt ons, an appropriate LSD ratio and a good driver. But low to mid 14s is more realistic
There should be a list of documented runs showing the time sheet, mods, weight, tyres, track, conditions etc etc if there isn't already.89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

M20's usually dyno, what, 140-150rwhp? M50's are supposed to be around 160-170rwhp right? So.... Why does anyone expect it to drop seconds off the 1/4 time with only about 20whp? My eta's chip gave me about that much, I'm lucky if it dropped 2 tenths.
I know that's only peak numbers, and power band is more important (and m50's with the variable valve timing are very good at broadening the power band), but I think everyone is being a little too optimistic.
S50's put out about 200rwhp, and run about 1-1.5 seconds faster then a stock m20 (when put into an e30). So with less then half the hp increase (in the case of the m50), I'd expect less then half the gain: ~.4-.5 seconds faster in the 1/4. Nobody has consistent runs unless they are a GOOD drag racer (I doubt anyone here is), so take the numbers with a grain of salt... and you'll see there's no surprises here.
Even when I drag raced my eta (I just HAD to see what it could do...) My runs varied by over .5 seconds, from 16.3 to 16.9. It's hard not to launch an eta properly, wheel spin really doesn't happen. That goes to show, the same driver in the same car can be off by that much, imagine a different car with a different driver.

But a hell of a good time, trust me!
Dont sweat it too much, you will enjoy the different style of power that the
M50 delivers, highway travel will never be so much fun.
May not be the quickest 1/4 mile swap, however the power is so usefull.
Torque down low, revs that pull hard create a very fun car to drive.
Power you can use when screaming up canyons in third!!
Obviously a S50/52 will be faster, however that may not be in your budget.
I know it wasnt in mine at the time, I opted for the M50 and it was a blast!

Originally posted by Mr.SWISS View PostTrue, that's why I chose the non vanos so I can easily get the AA s/c when time and funds allow. I also don't think any of these M50's run have been modded. I put the M3 peformance clutch and 11lb single mass fly over the 40lb dual mass on it and it revs really quick. Night and day over the old M20 I had. I think after I put the Schrick 252 on the intake and move my intake cam over to the exhaust side I will get another 20-30 more with the Turner chip. After that I plan on under drives and a better CAI that is blocked off from the rad. I think my 0-60 is around 6 now. I hope to have it down to 5 when done.
