nice numbers, did you have it dynoed before the HFM and 24lbs injectors?

[BlackE30]

no thats the 1st time I have dynoed it after buying it. It ran like shit all the way till last week. Its still not perfect but much better.

[sharksforthecup]

wow i'm especially impressed with that torque, at somewhat of a low rpm.

[BlackE30]

My goal was high 230s for the hp but I am happy with the torque curve! I didn't think it would be that high.

[PiercedE30]

Wow, once you get your AFR's looking better (ie, where they should be) you should be able to pick up a few HP in the low - mid rev range and it should help with some of the dips in the graph.

EDIT: ^Beat me to it.

That's a pretty ragged looking pair of power curves there, get that bitch properly tuned and you should pick up some power and throttle response.

You're running really lean until above 4.5k.

[BlackE30]

what do you recommend I do? not trying to spend a whole lot, It has the Jim C Chip in it. The 2 larger drops are the vanos.

[PiercedE30]

Get a scanner and see what your LTFT's and STFT's look like. I'm betting the LTFT's are maxed out.

Too bad i didnt tighten down the overflow cap enough, that guy would have been even more surprised had he not had to pop the hood. "I had no idea THAT was in there!"

Good peaks, but she's laying down fast. Check the casting number on your cams and PM them to me. I think you've either got a big restriction...or you have 2.8L cams by the looks of the curve. S52 cams will peak at 52-5400 and carry most of that peak 7K. Your curve looks like mine when I had 2.8 cams in my S50. Don't ask me why I had 2.8L cams in my S50...

On a different note: I'm using a Cosmo AFPR and can add and take away *some* fuel with the adjuster. About a full point up or down.

From my experience, the car won't really make any significant difference in power, but you can move the fuel curve around. Ask Kienan (the owner of All Aspects), he's seen my car up there plenty ;).

My S50 3.1L made 238/229 SAE on that same dyno,@65psi.

Attached are two sheets, one with 2.8 cams and the other S50.

Hey Ed, Yea this is Jeff with the old black turbo e30. I was talking to Kienan about your car not realizing he knew who you were but then we got on the subject and were talking about your dyno runs for a while. Thats interesting to think that I have 2.8l cams, I am afraid to check. Maybe its just time for some performance cams anyways....

Looks good. Seems like there are some more bugs to be worked out by that graph though.

[ed94r]

Jeff,

Maybe a dumb question, but is the speed reference sensor hooked up?
