Is this the car that just installed the lower pulley on a couple months ago?

99lightning

yes and we went back to stock crank and did the upper pulley instead.

Torque looks great on that graph, so flat

sircl55amg

what size and brand was the lower

99lightning

we had put a stock lower back on the car this was upper only

JoeNobody

What size upper? The smaller clutched or a fixed pulley?

99lightning

that was the clutched today.

What size upper? Looks good!

99lightning

I think it was the 84mm

kponti

Wow almost 500 to the wheels, what other mods?

99lightning

kleemans with just front cats removed, belt wrap kit split intercooler.

Wow impressive!
With only 10rwhp difference between the 77mm solid pulley and the 84mm clutched pulley, I'm tempted to sell my solid pulley, stay with my clutched and get a BIP tune

99lightning

yea the clutched is impressive, Keep in mind on the fixed pulley car the afr is about 10.8 most of the way we did not touch fueling at the time since we wanted to make sure all was good. Also with the fixed pulley car it was driven to the dyno fully warm with a 15 min cool down, I would expect it would make between 520-530 on the dynojet Once fully tweaked.

What feels better for normal and spirited driving? I like the idea of the FSP but not sure about long term supercharger wear.

99lightning

If you can be super super light on the gas you cant tell one from the other creep into a little bit and the car takes off with fixed pulley.

99lightning

if your near buckhead, you can probably go over there Jason's car has the fixed pulley

Just loaded and installed my solid pulley and tune. Few teething problems with tune so taking it extra easy. Any ideas how I can reset adaptations without star? Time isn't helping me get to a star unit early enough
