Nice. This is with AccessPort, too, right?

 

yes this is using the AP. FYI stock GSR puts down ~230whp on this dyno

 

Wow that dyno looks like it reads high compared to others on this board. Nice numbers. What does a stock X make on this dyno?

 

Nice, so how does the car feel???

 

Nice numbers, I'll be heading their way soon as well! So this is a claimed 100+ whp/tq increase over stock?
P.S. Were you on Bryant Irvin in FW the other day?

 

Feels like a beast, I keep grinning when the torque kicks my *** at 3k and on.

Yep ~125hp over stock. Not bad for the few mods I've done.

As I said, 230 for a stock gsr. It reads low compared to most others ive seen, though more than buscher's I believe. It is a mustang, do all the Dynojet number are much higher than this.

 

good number with those mods.

 

NICE NUMBERS ,MUSTANG DYNOS ARENT ADJUSTIBLE FOR DRIVETRAIN LOSS LIKE OTHERS SO THESE NUMBERS ARE REAL.

 

Nope. That's what I thought too until I dyno'd on it and got within 8whp of what I got on a dynojet in LA (with no changes to the car). It reads like a dynojet.

Still great numbers though!

-M

 

LA is 91 oct and TX is 93, no?

 

thats what im shooting for once i get back on cobbs dyno. i basically have same mods as you except its cobb pipes instead of ets and ill be getting an ams downpipe. hopefully i can get both teh downpipe and intercooler at tax return time, unless that is i actually make money in vegas in a few weeks for once lol.

 

I was on Meth. Wouldn't have made a difference.

CA: @ 25psi on 91oct + 100% Meth = 350whp/354wtq Dynojet
TX: @ 25psi on 93oct + 100% Meth = 345whp/342wtq COBBs
TX: @ 30psi on 93oct + 100% Meth = 367whp/386wtq COBBs

 

Dynojets seem to vary more than other brands. The DD in our area reads low even for a DD, which is why you see some skepticism from the Minneapolis crowd now and then.

 

Very nice!
