yes, street twin doesn't slip well
Should be in the 500HP range, On the initial pulls saw 460RWHP with near 9:1 AF. So rich it looked like a deisel!)
I haven't had it on the scale lately, I know I need to get weight off the front. Car is heavy,
only things removed are front sway bar and cruise control module and cable to TB. Add blower, all the piping for the front mounted 3 core, cage (steel, not CM), and my Big fat ^(*# and I would say the cars has to be in the 3900 LB range or maybe more. Rear suspension is all Spohn adjustable: TA, LCAs and PHR, air bags in springs and polly bushings in the stock sway bar. SLP SFC and level 2 shocks and springs = 1/2 drop in ride height (I know they hurt the launch). Rear is a stocker: 3:73s, Welded tubes, Mac TA cover, spohn LCA relocators. I run -2 pinion angle with the LCAs in the middle holes of the relocation brackets.
Want list 1st is a rear, then QA1s and Tubular KM. I have most of the parts to relocate the batt. to the back.
Full throttle under boost in 1st or 2nd will just spin the tires. I normally walk it off the line, 1-2 shift @ 4000 RPMs to minimize wheel spin, then let run it up the RPMs. Last time at the track tune was still slightly rich and timing was pulled back a bit. Make two passes both in the 12.4x @ 125MPH when it spun the bearings.
Have the wideband installed and in the process of breaking in the new engine and tightening up the tune now. Need to get it on the track so I can go into the upper RPMS and log data. Not easy to do on the street with this thing - Ask Josh!
