Z3 Upgrade latest

As promissed here is the latest update on my Z3 upgrade.

Remap done this morning, not very impressed with Dashfixer no tyres pressure check nothing. Drove car in straight on rolling road for warm up run. Remap written and installed. first run not to bad but Power and Torque lines all over the shop.

First run results are:Power 206.7 bhp @ 5,594 rpm Torque 206.7 lbft @ 4,279 rpm. Remap changed after first run.

Second run:Power 208.7 bhp @ 5,560 rpm Torque 211.3 lbft @4.268 rpm.

Power and torque lines are now as smooth as a babies bum, with no peaks at all drives very nice and power is so nice without any flat spots. However using Shell V power fuel will improve power even more, also checked tyre pressure when I got home and back tyres where down to 27 psi so have put them up to 31 psi.

See you all on Saturday Onno

Have you put the M50 manifold and BBTB on yet?or are you still running the restricted one on the car?

Onno

Is that flywheel power or at the wheels, if flywheel what was your power at the wheels

Yes my friend this is true but from what i am gathering the man is after power, and by adding a free flowing exhaust and less rectrictive air filter will also do no wonders for his torque figures but aid his power figures and help the engine breathe better.

Have you done this m50 inlet manifold and BBTB conversion to a car of your own?

how many cars make good power between 2k and 4k? if onno was after power in that region he should have looked into buying a turbo diesel instead.

I was in Gaydon this weekend and spoke with a guy called jason from bm tuning who was kind enough to have a look at the remap done on Thursday he found that some of the changes made where done incorrectly and told me to come back in about 30 minutes. As you know Iam not a believer in doing anything without a r@r but this guy has done wonders ( previous power was all at the top end ) now it is through the whole power band. Driving along the M6 on our way back the nose off the car coming up at every level when you put the foot down even in 5th gear at lower revs it just kept coming up no down shift required. result great. Maybe go and see Duncan tomorrow and do a run at the rolling road.

Cheers Onno

As you know I have done the M50 engine as well. with ported head, cam change, 6 branch manifold, SS complete system, induction kit, opened up throttle body, changed airmass to airflow meter etc etc. So if i wanted to go that way again I would just fit an M3 engine into my Z3. Iam just having some fun at very little expence.See you soon mate.

Cheers Onno

Onno do the e30 325 and the e36 325 share the same top end and inlet manifold??

I thought they were different?     

Yes onno its a worthwhile modification to do on your 2.8 as your currentlly running a 320 inlet manifold and throttle body. Read into this conversion on the e36coupe forum.
