New 60-130 record: 6.14
#16
Awesome acceleration. That it what you call some serious "midrange punch" I would imagine power like that makes overtaking on a two-lane road fairly easy
Being the gearhead that I am, I have a few questions; Did you run a different setup for the 60-130 than you did for the 1/4 mile? Just out of curiosity, what gear and rpm's were you at when you started the 60-130 run? Was it part of a much longer acceleration run? (like 40-150?) or was it a "level off at 60 then stomp on it" run? If it was a start from 60 run, did you left foot brake to build boost? From the telemetry you posted, it looks like very strong power through the rev range, as opposed to the peaky-ness that can sometimes occur with high-power, lower displacement turbo motors What kind of HP do you think you are running? Based on your 133-136 traps, my guess would be around 600-650 at the wheels.
Again, awesome machine and congrats on some amazing numbers.

Nice set of questions. To start with, the car dyno'd exactly at your estimate 620rwhp with 650TQ on dyno dynamcis, most conservative dyno in US. Since these turbos are smaller in compressor wheel size the boost comes in pretty quickly around 1500rpm and max boost at 4000rpm. To get a good 60-130 with these turbos, you need to roll from 45mph in 3rd gear then punch it as hard as you can. Since my car's rev limiter is set at 7500rpm, I still shift it at 7000rpm. A quick shift will do the trick, then ride out the whole 4th gear until passed the 7000rpm, then you got a nice number. BBi's amazing job comes in here when they custom fabricated the Y pipe and added the blow off valves in the bottom of the intercoolers vs. the proto style on the y-pipe. I went thru 4 different softwares to where I am today. The car is breathing immense power throughout the whole range. Now with new custom fabricated turbos we are goingto raise the bar on stock internals with lower boost and more power. This is engineering at its best and the whole trophy goes to BBi. Hope I answered all your questions bro.
