The 3.2 Alpina Powered Chromie

Wed Jun 06, 2012 1:46 pm

Chip Wizard mate, dont know what the setup is exactly but its as good as they get, he does race cars for a living and the power has to be right or they get lead in the cars

Shame I did not know you where up at the York drag strip - only 10 minutes away from me!

13.5 is a great time!

Wed Jun 06, 2012 6:11 pm

You will have to get your car there once done

Took the cam cover off this afternoon and as suspected the exhaust cam has slipped on the sprocket and is retarded, at least 5 degrees, inlet is still bang on the mark with the crank.

Will be rebuilding this with loctite, never known one to slip before

Quick time

Wed Jun 06, 2012 6:50 pm

iirc the torque setting isn't very high on the nuts at the end of the cam. From when i had the head off.

Wed Jun 06, 2012 6:54 pm

You might want to give them a bit more if you followed the torque settings!

Swapped the vanos seal and put the timing right today, thought I would have a go at monkeys method, straight forward and doesnt affect timing.

With the vanos unit un-bolted there are only 5 bolts to remove, most difficult one is at the bottom

Still plenty of room to get a proper spanner on though

Rags at the ready as the unit is still full of oil, but once removed the job is a doddle

Old stretched outer and hardened inner Vs new

Didnt get any pics of the exhaust sprocket but its now bolted up to the cam with loctite and an extra tug on the cam bolts. Will wait for tomorrow before starting to give the loctite chance to harden

It will do better than that now its timed up proper with new vanos seals etc.. im trying to work out how it could slip a tooth.

Would standalone management work well with this?

Thu Jun 07, 2012 11:16 pm

Floating sprockets Lee, its just the clamping force of the bolts that holds the timing.
No need for standalone at all, nothing wrong with the Siemens on these and they are very exploitable in the right hands.

How much power did it make with the 3.2 ECU and bigger MAF?

Thu Jun 07, 2012 11:35 pm

It was about 260, did loads of runs and they varied slightly depending on the ECU adaptions

Thu Jun 07, 2012 11:49 pm

Strange it made more power on the 2.8 stuff, even with a smaller MAF. Id definatley look into the injectors too, running out of breath at 250hp aint doing it no favours.

This will be awesome when its running right.

Fri Jun 08, 2012 9:17 am

I think it was just how the ECU was trying to correct for the extra valve overlap, fluke really, exhaust cam position doesnt affect power much either.

Fri Jun 08, 2012 9:22 am

if alpina fitted those injectors as seems the case, there is no way they won't be flowing enough for the engine. It will be a problem elsewhere.

Now back in action

Fri Jun 08, 2012 7:09 pm

What does the arse dyno report?

Fri Jun 08, 2012 7:10 pm

Not been out in it yet

Mon Jul 30, 2012 10:48 am

dan would you recommend monkeys method of doing the vanos or should i go round the slow way?

Mon Jul 30, 2012 11:34 am

also : wow what a car just read the lot!

Mon Jul 30, 2012 11:58 am

Just replied in your other thread mate, monkey method

save loads of time, I did one last week in about an hour

Missed this post, yesterday at Santa Pod I was doing 100mph, ive been clocked at 103mph before at York.

The left outer CV joint failed yesterday at Santa Pod, so I took it apart and cleaned it a bit today to see the damage, right mess!

Chewed up good and proper, will be looking for either a pair of new outer CV joints or one very good second hand to replace with.

Thanks to Andyboy for driving me to the scrapyard for a replacement driveshaft

Epic motor... I Was giving my mrs n little bro the down low about your car when the joint went. She felt sorry for the car! It'll be back stronger hey!

Mon Sep 17, 2012 10:57 pm

And Dan you were doing well chipping away at that time until you decided to take a pasenger. (i did tell you to ditch that fat B__s_rD). You were jinx,d we got hauled off the line last year when his belt shreaded! (only joking Ad). I give you your due,s your up there every year going for it

Mon Sep 17, 2012 11:04 pm

Not many felt sorry judging by the cheers as the CV went bang, coonts

The yellow drag prepped E30 also did a CV joint on the run before mine, he said he'd done two in two months, so it sounds like a bit of a weak point in the drive line, better than a broken diff though!
When we got back from the scrappy there was an E36 compact stranded, also broke a CV.
Will be taking a spare or two next time I go drag racing

He was never going to make me faster really

Looking at the time sheet even though I got away quicker I was doing the slowest 1/8 mile of the lot, was 2mph down at 1000ft and the slowest 1/4 mph of 99.47

Mon Sep 17, 2012 11:09 pm

Spare prop and diff too!

I've heard about your fancy diff too ...

Mon Sep 17, 2012 11:19 pm

It's the launching that kills of the shafts. Saying that I've done more diffs than shafts

It's a Shame that it let go. Anyway personally I think this cara drag strip days should be numbered. Leave it for fast road and an occasional track day
