Stock kit tuned on a vafc II with a berk testpipe and 2.5 custom single exhaust. I tuned on a dynapack which i thought read higher. My tuner says that his dynopack reads %10 lower than a roller dyno . They're was a 02 gt mustang vortech supercharged said he did 390whp on a dynojet and dynoed his car on this dynapack and dynoed 360whp. So....i don't know what to think. my tuner said i should be in the 300's on a dynojet. anyways i did 280whp 180 ft lb tq non-aftercooled. ill post up a dyno sheet asap. my vtec set at 5500 5600 rpm.

 

with that final gear you must be hitting vtec too fast. even cruising at 85mph in vtec right?

 

I'm close but I cruise around 65

 

Was the 02 GT silver? Caleb? I think we might go cruise around today around 5pm if your intrested.

Anyways, a Dynapak does typically read higher than a roller dyno. Could be calibration. Either way nice numbers

I think his name was caleb it was silver though with a supercharger. I'd go cruisin but I gotta go to my gf's little sisters birthday party....so ill be drunk by then

 

Yeah, it was just recently supercharged. Hopefully ill get a chance to mess with it today. His other mustang is awsome, ive tried to buy it off him a few times with no luck.

 

I just had my vortech car on a dynapack. He said that most stock s2ks put down about 190rwhp. I ended up with 300hp and 200ftlb. The dyno is great for a before and after measurment, but I think it is true that all dynos are different.

Just make sure you go back to the same dyno when you get new mods.
