gotta disagree brian. i ran my c3 without any other mods except cooling and i felt a tremendous difference. the low end torque was evident. no add a tune and its amazing!

 

I installed both, felt a huge increase in power or was it the screaming supercharger siren that deceived me.

I changed to a Needwings clone (for filtering reasons) but really miss the cool sound coming through that green sponge.

 

now the car has needswings intake and c3 pully,, one note the belt sits on top of the pully (in otherwords the belt is higher than the pully) where as my c3 pully the belt rides inside ,,flush with the pully, if that help to find what pully this is, jim

 

Then someone needs to pony up to a dyno session...and put this to rest..

The S/C pulleys are simple to swap - so it should easy - three pulls with the factory pulley, three pulls with the Code3... on the same dyno - on the same day... you won't even need to hop off the dyno to swap..

My comments are based on comparing my SRT's dyno results with the baseline dynos that Code3 ran - I ran on the very same dyno Code3 used baseline his pulley - with the owner of Code3 right there to witness my pulls....same shop, same dyno.

The data I saw - is the data I saw...and it's the same data Code3 posted on the forum to market his pulley. Perhaps he just had some really poor pulls (massive belt slip, etc...) and you folks are experiencing better results.

 

No one needs to do anything....how much longer are we going to beat this dead horse. There are at least 50 threads on here about this very topic. I have friends with 185, 181 and I have a Code 3 pulley. We all have intakes, tunes and can drive. All three cars ran 12.2 on the same track, on the same day....there is no better test than that.

Each car in each part of the country will react a little different due to altitude, but until someone can tune these cars...on the road..not on a dyno, the 181 and 185 will not be faster than the Code 3...at least in TEXAS.

 

Yes, I meant at the crank. You can also figure about 17% in drivetrain losses for this tranny.

 

i ran identical times (exactly the same other than trap speed, mine were a little higher) than a car with a 178mm pulley at MIR. We both only had tune, intake and pulley.

just search the battle of the pulleys thread.

 

How many miles on the car? Check your stock heat exchanger. Mine was so packed with sand it was doing nothing. Blasting it with compressed air for what seemed like hours made a huge power difference. Maybe you C3 pulley is just giving you hotter air and your pulling timing.
