1st dyno attempt

[Jeromy]

last night the local club had a dyno night so I figured I would see where my car was at. Car has headers, cat back and fipk. 272 hp 310 tq. I not sure if it still has the stock tune or not.

here is the sheet

First of all I hope they did not use an O2 sensor in your tailpipe during the run. If they did you are too lean for WOT. Lastly, HP and TQ are always equal @ 5250RPM. The chart attached shows them crossing well before 5250. That seems odd. Otherwise the numbers look good.

Sounds like a tune might help out. The numbers seem just a hair low. How did it look with a smoothing of 3? Or did you not get a chance to see that?

what headers are on there?
good numbers though i strongly feel they can be higher especially being an M6.........



i just looked at the sheet 3600-3800 seems to have an issue,when was the last known tune up?

They cross at 5250 I believe only if the scales for the HP/TQ are the same, if you look one side is scaled to 300 the other side is scaled to 320 so I think that's why they don't cross...

I am not sure exactly how it all works, but I did see what looks like an o2 sensor that was in a tube that was stuck into the tail pipe.

I did not see it changed.

I was worried about the emissions here so I went with the pacesetter emission legal mids. I mostly put the headers on because I broke all of the studs off the stock ones when I took it apart and did not feel like drilling them out.

I bought the car with bad head gaskets, I just got it running a couple of weeks ago. I had the heads rebuilt and put new taylor wires and ngk plugs in it along with the headers. I wanted to replace the opti while I was at it but did not find the $.

Couple of the guys last night though I may have a spark issue with the way the hp curve is all jagged, said it should be smother.

the dyno graph looks as if it is electric related in ways.....

Could be. It just looks weird that way....
