[silversleeper]

I don't have a pic yet, but I ran my 86 friday night at our track.

2.294 60ft
9.951 @70.82 1/8th
15.400 @89.74 1/4

This is not a stock eta. But it isn't an I either.

Damn, you are quicker than me! Nice time, now work on that 60ft.

where did u get ur long tube headers?

[e30_325es]

I gotta fix my diff first. That was using a 4.10lsd small case, that I broke on my last run. I just put my old 2.93lsd back in (but need the rest of my exhaust back on now) and the symptoms are gone. I'd be interested to see how the 2.93 does.

How far from MIR are you? I think that's prolly the closest track to the 2 of us.

Oh, and some of my specs: ported 200 head, 283 cam, 325i intake, tb, electronics, m30afm, chip, and long tube headers w/ 2.5in full exhaust.

the diff acts as a gear reducer. my 4.10:1 LSD would act as 4.1 turns from the drive shaft before the axle would come full circle

[threlevenguy]

so is the input shaft past the driveshaft? and by counting you mean count the revolutions?

[xLibelle]

jack it up, put in neutral, hand turn input shaft and start counting.

[PiercedE30]

is there no tag on the diff itself to clue you in on the gearing?

7 series rear end

yea the guy who "built" my car said he put in a 7 series rear diff. but i cant prove that it is. it looks different than my old 87 325e's diff so i dont kno. i think the gearing might be 3.15 or 3.45 ...not sure. more info when i get a hold of him

[Axxe]

Sorry about the OT, but to the original poster, details about the 7 series rear end?

[xLibelle]

i think it maxed at 9lbs but it came fast - 90% of the power started at 3.5k rpm being about 200 whp

[Jonathan M3]

xLibelle - now that's better! I am seeing these 15 second passes and having drawbacks to when civics were drag racing and braking into 16s and 15s like 5-8 years ago lol

Is it difficult to get a good 60' in e30 (ie. 1.7 or so) ?

You forget these cars are 20 years old.

Yes a good 60' is possible, around 1.9-2.0 is pretty easy to get with a good launch and well prepped track. I had cut several of those on stock weaves/street tires with my stock motored M3. However, a 1.7 would take alot more power than what most stockish E30 motors are making.

[ptownTSI]

nice! 13.8 is a great time, how much boost are you running?

[ptownTSI]

when i think of slicks i'm talking MT E/T streets. although Nitto might have a 555R in a 14 or 15" nowadays these can be driven on to the track. BFG also has some nice drag radials.

put some super skinny tires on up front, and the grippiest you can get in the back.
