Yea, I had the car dynoed on a dyno/dynamics dyno, it reads very very very low in comparison to even a mustang dyno. The a/f's were rock solid 10.5-1 all the way to red line, although I may look again just to be sure.

 

CORRECTION!!! It appears around 6000 rpms the a/f gets rich at 10-1, everywhere else it is very consistent around 11:1 averaging 10.8:1 until 6000 rpms.

 

It also runs very very lean at the beginning of the run until the turbo spools, the guy that did the dyno recommending tuning in more fuel at the beginning and leaning it out toward the end

 

I have a weird feeling that over time it will get more sluggish just like mine did... Not sure if going that rich over time ruins the spark plugs quicker hence resulting in more sluggish feeling.

But yeah sounds like what I had to deal with originally.

Also not sure about the being rich first than leaning out... Should be as the boost builds the A/F gets more rich until you hit 11's which it should stay while at full boost... You don't want to lean out from that, or ummm you could hear a... Boom haha.

If you started off in 10's or 11's A/F man that would be drowning the chambers before enough air could pass through making a good ratio... Talk about flooding the motor LOL.

 

Those are still pretty good numbers if you ask me....what do you consider "lean" at the "beginning" of boost?

 

Yeah no kidding, my first numbers were 322 whp haha.

 

Miaplaya, have you had dyno's on your car pre and post installing the spacer? I was wondering what kind of gains you got. If I am correct, you put a motordyne on it didn't you?

 

Yes I do have that spacer. I have pres but no posts yet..

 

There seems to be new noises every time I drive this car, lol. Now before boost it sounds like a baseball card between the spokes of a bicycle, almost undetectable, I am taking it back over to my mechanic tomorrow to have them see if they can fix it. What do you guys think it could be?

 

No idea unless I could hear it in person...

But yeah considering the boost and LSD... Car makes all kinds of sounds now haha.

 

On Peking's pre-tuned dyno, the engine would go sub 10's at about 5000rpm or so. Power peaked at 350whp, IIRC and then went straight down. After retune with the EU, we made power well through the powerband, and ended up with 402whp IIRC. Peking can post the dynos, as I am going by memory.

 

Yeah I got them floating somewhere in this section... Let me see if I can find them... And hopefully did not delete them from my image hosting site to make room for other photos LOL.
