my dyno today

[joefufu]

I did my first dyno run today. It was on a mustang dyno in 4th gear. The only performance mod I have is the vibrant s-pipe back exhaust, with 94 octane pump gas and flashed. The car was running way too rich in lower rpm, here are the graphs

no comments from anyone? Is the numbers too low? How about the a/f ratio?

sounds about right for a Mustang Dyno....

tuning would REALLY help you out too.

I made more than that BONE stock.. my afrs were around .5 higher than yours. and I am flashed.. I made 141whp 143wtq bone stock. Same type of AWD mustang dyno. My boost looked the same as yours too.

Can the dyno really make that much difference? I put down 160hp and 166tq with just my vibrant exhaust. I was on a dyno jet.

hmm....the guy at the shop told me mustang dyno put out 13.5% less than dyno jet on average. That's why he put 156whp equivalent for dynojet. As advertise, no change in boost level for the vibrant exhaust. I might jack it up to 8psi when I have the money for smic

I always thought the Mustang dynos tend to put out higher numbers. Either way, I would never trust a number from a Mustang dyno, I'll stick to Dynojets.

No it's lower.

Joefufu...if you want a more comparable number to all these guys on the board, goto Davenport. I dyno'd my p5 there.

there was another msp dyno at tecmotion(the place i went to for this dyno), that car was bone stock, and it made 127whp on mustang dyno. That gives you some idea on the gain of the exhaust

 

[KySpeed]

did you guys dyno in 3rd?

 

[joefufu]

nope, that was in 4th gear
