well, today we didn't have much booked... So we tossed my summer tires on and decided to spin!



Im fairly pleased with the results, though I'd be happy with another 12hp to the wheels! The torque values are fairly low because the only tires I had were very bald and would chirp or skip here and there.

Here's a video of one pull:

 

what mods? what exhaust?

i like that the car is dirty, means it is working hard.

 

Oh damn, my sig didn't post.

Agency power headers + mids, stock mufflers, ROW airboxes, K&N filters.

It was -12 today with about a foot of half melted snow on the ground... Clean is impossible right now. I basically put it up on the hoist, changed the wheels, blasted the bottom to get all the rocks and slush off.

 

have you ever dyno'd the p31 in bonestock form?

 

That I have not. We did dyno before the headers, but the dyno needed calibration and was generating nonsense values and curves.

I did actually get a few 500-505 pulls early on, but the graph wasn't stable.

 

Nice
On par with the current mods.
