well i went up to DB today for the mnsortcompacts dyno day and had the cobra done again. something just didn't seem right about my numbers last time so i thought heck give it a shot. got up there and let the car cool for a few minuted and i was the first one on the dyno. i drained the intercoooler tank and cycled some ice through. Made the first pull at 509 rwhp and 480rwtq which was a gain of close to 34 rwhp and 30 rwtq. I guess last time the motor was heat soaked or something from tuning but either way i am happy with the numbers now.

 

nice numbers... however, they may not be accurate. If you're a ported eaton - they sound pretty good... but im just wary of "dyno days" because those are the times where the dynos are off for some reason...

but if your a ported eaton, that sounds about right. I would think your torque would be a bit higher?

 

i am ported with a lower. so it is pretty right inline. it's the same place i have always gone and the numbers are pretty accurate from their dyno to all the other dyno's in the area.

 

Nice numbers. What size upper pulley are you using? And what size lower? Numbers do vary from dyno to dyno.

 

2.93 upper, 4# lower, i kow numbers can vary but we have had several cars dynoed on the local dyno around here with no changes made and they seem to come back within a few ponies of each other.

 

Those numbers are right on par for a ported Eaton set up, with the TQ being a bit on the lower side. Nice numbers none the less

 

sounds good
