interesting valve cover...did you shave the ribs? any idea what power the m50 makes at 8 psi?

Haha Style 10's hell yeah!

This is a really crude way of measuring, but 14.5psi / 1 bar / 1 atmospheric pressure usually doubles your stock HP.

m50 makes 190hp I think, 165whp? 8psi is 55% of 14.5psi.
So if my math is correct, he's in the neighborhood of 255whp+. But of course lots of variables weigh in, so let's see what he says!

Clean work!
Would you mind posting some pictures of how you routed the piping out of the cold side of the turbo? (The charge pipe coming off of the turbo)
Thanks!

Nice work.


Sooo....... Hp?

[wenbeaver89]

Never had it on the dyno but going by what other people with the same setup are running, I'm guessing 280-310 whp. I'll try and get a pic of the piping too!

Interesting cover on the firewall, did you just use thing gauge metal to do that?

[wenbeaver89]

Ya that's just thin metal, Painted.

I'm digging it. It cleaned up the firewall a lot.

[ScHpAnKy]

seriously considering that, looks so much better than the cover that's already there

How difficult is it to turbo the M50TU? What kind of cost?

[wenbeaver89]

I pry got 3k in the turbo setup and tune, but that can vary allot depending on what your goals are. I got a few good deals from friends so that helped allot. Its not that hard but it does take some time and some fabrication work!

I need to find some round rubber grommets yet for where the ground wire comes out of there like i have for the boost gauge line but i haven't found any more.

Here's a little pic of the charge piping. The best one i could find anyhow.

Tastefully built car. The firewall cover and deleted high beams are nice touches.
