stan and I have the exact same mods, and we dyno'd at the same place. we even have the same downpipes and filters.

only differences that may have caused my poor results were, my engine had no thermostat, so it was running very cold and rich, and my tps was way out of adjustment. i've since fixed those two things and my car does feel better now, i guess it's time for another trip to the dyno.

oh, and i have 18x10 wheels in the back, and stan is on sawblades. I guess that could cause me to lose a good 10-15rwhp from drag.

Want to know a secret? Don't tell anyone.

I change my rear tires to 15's when I dyno.


I made my 310whp with no thermostat also. I had a cooling problem (bhg) and it would run too hot with one.

???

I use 15in rims to dyno with. It's proven that even upgraded in size calipers and brake rotors can rob up to 10whp due to more mass farther from the center of rotation. I can't imagine what my 18's would do if i dyno'ed with them on.

I can see why Ric is doing it. Its a dyno, Its to make yourself look like you have a bigger package than you do,


Go Lenny Kravitz style, stuff your pants.

Its a display of what a can can put down.

well i ended up somehow frying the ecu when i opened it, so we looked inside and it was a stock ecu. replaced it with another stock ecu too. iirc, jose said i've got 180 compression across the board, whereas iirc matt said he has 165. that could be part of the difference maybe? my engine is supposedly pretty low mileage for a 1j.
