Carbon intake of a s54? Is the e46 m3 crank pulley slightly bigger than the e36?

Im after some high flow cats but they are so expensive

carbon plenum made for S50, and the E46 M3 crank pulley is smaller, so it underdrives everything

Motorsport cams as in M cams?

283* is surely heaps more than a normal S50 cam.

It's awesome power - how many rpm is that at?

standard M3 cams are 264* I believe, my cams are a BMW part, from M division racing parts catalogue, I got them second hand, maximum power is at ~ 8000rpm, my limiter is currently at 8100rpm

I wasn't sure you could play with the cams on Vanos equiped motors, i guess if it's a BMW part, what was the approx price on the shaft if you don't mind me asking?

Pretty hard to believe it has 700nm but only 270hp. Turbo diesel? :P

That torque reading would be the tractive effort no doubt.

Can't be a diesel, note the peak RPMs

That's torque reading at wheels, which is multiplied depending on gear and diff ratio

That's what i thought until i got told that the diff ratio was to blame.

i think the top speed was around 220km

Seems I need to use stronger sarcasm.

Anyway, reminds me of that fella who swears black an' blue his NA 20b makes 690 odd nm. lol chassis dynos.

correct torque is divide by the diff ratio so if it makes 700nm 3.9 diff = 179.48nm motor as long as the run was doing with a 1-1 drive ratio as for power the TCF factor should be between .98-1.00.

i did a rb25 on monday 15psi made 367kw wheel and 360nm motor im sure everyone gets the picture

2.8L M20, 14.5:1 compression with custom JE pistons, extensively modified head, custom grind cam, triple webers, E85....this is wheel kw, not corrected to flywheel-

That's insane, such an amazing sound on the dyno! :wub:
