e30 m60b40 1/4 mile times!!

... or check the weights from ETK.

S5D-310Z 80lbs
S6S-420G 100lbs



www.bmwfans.info is very useful site ;)

or, yes, I could do that as well......

I totally forget about these items when I discuss weight.

well, the diff isn't changing, the driveshaft change doesn't add much i wouldn't think, but I know the M60 flywheel is heavy as fawk, more exhaust piping, etc.

The M62 stock dual mass is heavy, it's like 30lbs, but there are aftermarket options just very expensive. Exhaust manifolds on M62 is nice vs the cast m30 .

38, to be exact!



I'm taking my m60 e30 to the drag strip this Friday, I'll report back with my results. There is also an accurate scale on site, so I'll weigh it.

awesome, we will need detailed car setup specs as well to complement the weight, time and speed info.

m60b40, 5 speed, 3.25 LSD, 235/40/17 Sumitumo HTR-Z II's. GE 450/640 coilovers with Bilstein sports. UUC LW flywheel with Clutchmasters FX100. DUDMD chip.

That's about all of the relevant stuff I can think of, other then the fact that I'm struggling with a fuel injection/ignition issue that may or may not affect full throttle performance (I don't believe so).

Reporting in from the drag strip!

Weigh in: 2685!
Half tank, spare tire, full interior. I'm thrilled with that number!


Will report back with time slips shortly :)

[iamsam]

^^ that's a great weight there? what weight have you removed from the car if any at all?

also, let's see those drag slips!

[JGood]

13.6 @ 103

13.6 @ 103

how was the run? did you hook up well? were you traction limited or power limited?

[knuklehead92]

your faster than the new 370z and same time as the new 335i, pretty good for a 80's car lol

[JGood]

That run I hooked up very well. I'll post the time slip tomorrow, but it was a 2.05 60'. It was the only run that I really hooked up. I had two 13.8's with moderate spinning, a couple low 14's with a lot of spinning, and a few 15's that I literally just sat on the line doing a burnout.

I'm confident a 2.93 or 2.79 would give better results.

[JGood]

[iamsam]

why would a 2.93 give better results? did all the gears seem too short with the 3.25?

[Alpina]

"Stock" E30 V8's with M60 engines make around 13.5 - 14.5 1/4 mile times depending on the suspension and driver. So that's roughly the scale..

i think this is close to facts,,

my S38B38 ,,in a converteble ,,

i have 13.2x @ 107 mph 3.73 LSD Wheels 17"x 9" tires 245-35 @ 36 psi

and the car is 1450 kg or 3200 lbs

[iamsam]

JGood, doesn't 13.6 seem slow, since the stock E39 540i/6 is advertised at 14.0? Also, the guy quoted below ran faster with a similar powered motor and much more weight.
