I took my car out to a dyno tonight, and here are the results. By the way, these numbers were obtained on a mustang dyno.
267.2hp @5750 rpm
278.7ft lbs @3750rpm
My mods are in my signature. I was kind of disappointed with these numbers, I was hoping somewhere in the 300-310rwhp range. My afr was really bad though, starting at 10.8 and gradually dropping to 9.8 at around 5500rpm. It is time for some tuning I guess. Also better headwork, we did the port and polish ourselves on these heads. Bigger valves would help too. Looks like it is time to mod again.

By the way, do any of you know the equation to convert mustang dyno numbers to chassis dyno numbers?
Let me know what you guys think. Also, any suggestions would be appreciated. Thanks.

 

Get that AFR straightened out... Soudns like the tuning is severely off...

 

Yeah something has got to be wrong there (see below). FWIW my car is running pig rich as well... but on the original Opti, O2s and converters! No power mods of any kind other than the CAI.

I was on a Dynojet however. Don't know if that makes a difference.

 

Yea thats very low for your mods...somethings not right...thats more like a LT1 w/ a cai power.
