CCV solution for boosted motors

Time for a 5 link solid rear axle w/coilovers instead of the IRS... LOL

What peak torque levels have you had these issues?

I've been debating between going turbo or doing a swap of some sorts. I like that the stock driveline stuff is so light, but it's obviously fairly weak. I'd like to get the car around 2250-2300 pounds and keeping a light trans and rear diff in the car would help.

Its not really weak, its just sized for 125 not 400 HP... LOL

My last clutch was rated at 305ftlb torque. All these items broke at 17-18psi whic is where that clutch would blow out.

I'm going to dyno the car before the end of the year on high boost.

Oh yea I'm a very light E36

The setup you have will not hold what torque I'm putting down. Metric said the only BMW clutch I can use is a modified M5 setup ($1,100) or stick with my stage 5. My last setup was the 9# titanium flywheel with a 6-puck and stage 5 pressure plate.

I have a super light E36 so it does get loose up to about 70mph on 20psi boost. Yes I do have some seceret tricks but anyone can buy them if they call Metric and ask for the latest file on my motor. I will share how to cut weight but it is obvious to most people.

Yes I spray it if needed

If your clutch chatters it will take out both the clutch and the diff fairly easy.
Even at way lower HP.

The rear suspension on a BMW is not exactly beefy even on a seven series. most of the BMW engines don't slam down torque..

Tire selection is a huge factor as well..
