first day at the dyno

Yesterday i went to Lujan Motorsports in miami for a dyno day. I made 268hp@4300, and 297tq@5100 with my 1995 camaro z28 a4. I ran a little rich so my car was spewing smoke at high rpm's. I covered the spectators in smoke and caused them to run away.

All i got is K&N FIPK, 52mm TB, TB bypass, edelbrock shortie headers, full 3" exhaust piping no cats into a flowmaster muffler, and a shift kit.

Heres my car blowing smoke..


My sheet..

What do you think of my numbers? What should i do now? Also what do you think of the rich condition?

thanks.

Um, I think your graph is kinda messed up, I think the curve should be less, well, jagged?

The torque shouldnt start so low and go up, the HP usually does that. Torque usually stays the same, pretty high, and then slowly drops off.

I am not sure what the problem would be...

Nice car though

Dynoed too low for mods. Look into your rich condition. Did you dyno with a wide band oxygen sensor?

My guess is that the dip at around 4.2k could be ignition related. I would def. look into your rich problem. That dyno is to low for your mods. It also suprises me that power starts to fall off pretty good at like 4.3 and 4.4k rpms. I would think it might lose some power but it should look pretty good up to around 5.4 or so....

yea im gonna try to find a place to dyno tune my car, maybe they can help me out. i looked at some of the stock sheets and their making about the same as me in the HP, and over 300 in the torque. its disappointing. but yea the car sounds, and looks good. and it runs good too, except for the rich condition.
