The car is a VW bug sleeper. It will look very close to stock unless you look underneath where you will see 275/15 drag radials hidden under stock fenders. Could not keep the tires from spinning hence the weird sudden drops on graph.

Yeah, 1st is useless. Rolling on the power in 2nd, 3rd still breaks traction.
A stock Super Beetle puts down 32 whp. This thing is 16 times that power level.
When you lay into the throttle, you absolutely have to mean it.

Yeah, I saw the title and kind of blew it off since they're old dyno always read way high. A proper calibration mustang is different though, and those are some good numbers.

Yimi changed location a couple years ago. Maybe that was when they made the change. Of course, it's a 4 wheel dyno and has small rollers. What I really needed was a dyno with bigger rollers (2wd) as traction on the small rollers was difficult.

S.I.C.K. I've never driven a beetle without the craptastic transmission and weaksauce engine, can only imagine how much better it would drive with a subaru transmission and metric crapton of power!

Thanks, the body is off for body and paint to bring it back to it's original 1973 Marina blue.
Since there isn't a reverse R&P option for the stronger 6mt, I'm stuck with a 2009 5mt. As mentioned, PPG 1-4 helical dog engagement gears were used. To help the trans survive, larger SAE case through bolts were used to help keep it clamped together. Finally, to keep a friendly conversation going on between the R&P, I made a chromolly girdle which also incorporates load bolts that hold the carrier bearing adjusters from deflecting.

I was able to get (inside) webs on one side but there wasn't enough room between the frame horns on a VW for ribs on the other. What you see is all that would fit. Being that everything is like one big dimensional sandwich and made from 4130 plate, even the flat plate with no webs helps, IMO. The plate is .190" thick.

Yeah, we couldn't keep traction. There was a tire rubber all over the dyno room.

I'm part of the VW 2.0 crowd. Had a hopped-up bug as a teen and now again at 60. Only this one is a little different. Just couldn't come around to dumping thousands into a VW motor to get a meager 200 hp.
Yes I saw the Love Bug in the theater
