Went to the dyno today...

Had it been 50 degrees like in the rest of the country, it would probably have been closer to 155 whp I'm guessing...


The guy said that the air/fuel seems a bit rich I think, so the M30 MAF conversion might be quite beneficial...

What has been done to your car?

[sweetride01]

Just a Jim C chip. My car is a 5-spd (of course). Nearly 150K on odometer, and I use Chevron (93 octane). :D
Also, I have a new OEM Ansa exhaust.

nice numbers

Wow those are some nice numbers.

I had my eta with a chip dynoed recently also, and I came out with 120hp and 152 ft/lbs of torque.

So the real difference is about 25 more Hp on the I, with 10 less ft/lbs of torque then the E.

yup until u make a I stroker.

which get good torque even quicker

yeah once im done throwing another 3k in mods then ill start buying stuff for the stroker.

The weird thing is, the computer said I had 149hp, but the printout says 145.
I will upload a video when I get the chance.
And at 17% drivetrain loss, the car is making 180hp at the crank, using the 149hp figure.
So, that's just as JC advertised: 168hp engine, +12hp at peak power, equals 180hp. :)

close, you have convinced me to do something, so I'm going with the 731 (out of 323) head and a mild cam :)

looks like you are actually running alittle lean, don't do m30 AFM, its a waste of time. If anything I would do M50 injectors and that with richen you up perfectly. you want the car to be between 12.1-13.1 on NA BMW motors for maximum power. you can see on the top end past 6000rpm it starts to lean up again back up towards 14 and u can see the power fluctuate on the graph at the corresponding rpms. anything below 14 is still safe but anything over can start to cause trouble. If you plan on adding intake and exhaust, just keep the M20 AFM and do intake and exhaust and then M50 injectors and that should be plenty with your Jim C chip. Those are fantastic numbers, you should be very happy with your motor pulling those numbers on a very lightly modded M20. congrats

Can I just do the injectors? Or would you recommend the intake as well?

do the intake the throttle response alone is worth it regardless if you loose hp.
