I'll definitely be getting another shop to do it this time around. Too bad I don't really have many options nearby.

^ They also have a better dyno.

Just got back from BPC. Everything is fine. The first shop I went to were a bunch of fools. My AFR is normal and the car hit 165 on the dyno.

Ruddigger · 09-07-2016, 08:17 AM

165 with all those mods? I'm confused.

Probably speed reached while dyno testing. He was saying before that his speed was limited to 120mph or something like that.

That is max speed in his 5th gear.

His car is automatic. I am assuming 18 inch tires, 5th hear ratio of .85, final drive of 3.73, and redline of 7k. Max speed is 164mph.

In 6th gear, theoretically he could reach 208 mph.

No, I mean the car is supposedly electronically limited to 155mph.

hassmaschine · 09-07-2016, 11:34 AM

158 (255kph)

the speedo will probably read 165 before it hits the limiter.

It is, but you can kill that with a tune and yes, top of 4th gear was 120ish and top of 5th was 165

This was going off what the roller speed was displayed. Also I've had our n52 hit a little over 170 on the dyno as well

Op, Bob?
What were the final numbers?

did you tweak the K-factor to force it to go above the limiter? It took me a while to figure out it was in meters per pulse (48 pulses, about 2 meters in circumference, divide the two and you get the scaling factor). Not the ideal way but I suppose it would work.

Thanks again, Bob

I'll be trying to come up with expensive excuses to get my car back at BPC.
