Swap 1/4 Mile Thread

[hoveringuy]

My daily driver is an e39 540i 6speed and at times it feels faster. I know the 540 couldnt post up a time like that though. I am much more confident in the e30 now.

I edged an e39 540i with my M54 and I'm a high 13 second car.

It's not faster.

what have you been driving that makes you think it would be faster than it is? You should take me for a ride, I'm curious what an s52 feels like.

Did you drop tire pressure a bit to see if it would help at launch?

What's your rear suspension set-up?

Thanks guys! I didnt try dropping tire pressure. I never tried a burnout either, went around the water everytime. I went out very unprepared. I had no helmet and didnt know what the requirement for needing one was. I had to borrow one after that first run :p. I am running turner j-stock springs with bilstein sports.
Now I am curious to get the car dyno'd because the previous owner of the engine was unsure of the mods because his uncle built the s52. It didnt pull as hard as I was expecting after finishing the swap and I thought I may have overlooked something but it looks like its all good!

[LivingLegend06]

Nice job mac.

I ran my car last night at the Woodburn dragstrip. I have never gone to the strip before and my first run was my best for the night. Here is the slip.

That's smokin' fast! Nice work!

My first run is always the fastest, too. The harder I try to go fast, the slower I go.

It was 80 degrees out.

1989 325i
S52
zf320
3.46lsd
TRM chip, 21lb/7k
ebay headers, no cat, no name muffler
2700lbs last week on a truck scale
225/50r15 in back Kuhmo ecsta cheap street tires

I am very happy with the result and now that I have been to the strip I cant wait to go back.

Wow nice work! Trap speed is definitely capable of high a 12.9x! :woowoo:

Get that 60 ft. down to 1.9 and you're golden! :D:D:D

Ran a 14.2@88 mph. 60ft was 2.03 with no type of launch due to street tires. Bounced the r3v limit in 4th and coasted through the finish.

S50
ZF320
3.73LSD

Will have 2.93 in for Family night next wednesday at Island Dragway.

[E30auddie]

Yeah, the tires are getting pretty slick. I'm gonna try and fit 215s or 225s just don't know if I can.

New chip and injectors are sitting at the house waiting to go on. And I did have a 3.73lsd but I do alot of highway driving. Plus I figured it would only maybe save me a couple tenths because I spin alot with that diff.

[Wanganstyle]

Need some wider rear tires to get the 60' down and should trap sub 13.5 and ~105-6 ;)

then can bump the gearing too and shoot for 13.2, strip some weight, dave can build you a high locking LSD and then you can shoot to go 13 even after you get the right chip setup :P


13.6 is pretty awesome with incomplete brains!!

[328ijunkie]

^ftw

[E30auddie]

Bump!

Et: 13.6@102/ rt: .096/ 60ft: 2.132
S50/ZF 5sp/2.93lsd
Unplugged 3.5" MAF, K&N filter w/ no heat shield, underdrive pullies, eBay headers-single 2.5" w/ single in single out 2.5" magnaflow, Technica Motorsports tune, 205/55 Goodyear Eagle GTs.

My MAF is unplugged for now because there was a miscommunication on specs for the motor and the tune is for a 3" MAF so the motor freaks the @&;!:'s out and runs like "poopdick." And I'm also working on a heatshield because I know my intake temps are upwards of hell degrees.

EDIT: the swap was done by a good friend of mine. Markert Motorwerks. Does awesome work!

[sasha18yug]

Thanks for clearing that up for me..:)... nice to know that there is an alternative for m3 cams... good times...maybe with some wight reduction and good tires ...you can hit 13s...:D

[Toadleg]

So they left the lobes but ground down the base circle to add some lift and duration... alright.

Exactly! Poor mans Cams
