Swap 1/4 Mile Thread

I have a cam card I can read off to you at what lift do you want to know the duration? They are factory cams but they grind the bottom part of the cam to make them bigger. All dynos are diff. I wouldnt go off that and to judge the car the dyno could be a lot different than another you know how that can go.......

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

If I could have a Redo I would of Done the M50 vanos engine than used the s50 Cams and than had those reground for a lil more kick........

[Toadleg]

My biggest problem was I cant use the m3 cams because mine is a non vanos. Cams are pretty limited Or expensive

At the time i had the m42 tranny and 4th was 1:1 but they had the car tuned in 3rd so im not sure how much that changes the results....... But it was 200 whp On a unsmooth graph and 195 when smoothed out @ about 5800rpm.They are factory cams that I had a local shop called Delta do a regrind on them I can explain that more if your unfamiliar with the process.

I have heard something about that... i am not familiar with the proces but if they make power for less then the m3 cams then they are worth it...

[Toadleg]

They gave the run around for awhile so to make things right they did both cams for $100 to keep me happy and it worked

the G250 and it was close to the top of 4th with the 3.73 lsd.if you look at my other videos all my mods are listed but it was tunned at miller performance on a dyno.

ZF/G250 same difference. :)

reground factory cams,intake, full exhaust, G250, Lightweight flywheel, War chip on dyno tune..... Thats it for performance I think, O and no ac or cluth fan

What specs did you have the cams reground to, S50? You didn't make ~200whp with an M50TU with stock cams and internals.

Also, how much did the regrind run you? Just curious.

I recently got my m50 non vanos swap done and ran it recently at the track at full weight and street tires ran 14.3 @97 mph

Are you running a ZF and a 3.73? You're at the top of 4th at the end of the track.

Man why are the 24v track times so slow?
I did 13.9 @ 98mph with my M20 2.7i
and another friend with his M20 2.8i did 13.5 @ 100

Both on Toyo R888 and both cars wheight 2,500

Look at the 60 ft times and you'll see, everyone is getting horrible traction. Hardly anyone launches their cars properly because they probably have a rear suspension set-up that's too stiff, with too small of tires.

E30lolz from Bimmerforums ran a 13.07 @ 105 in his s52 E30 M3 on street tires. 12s are possible with a proper suspension and the right tires.
