Today I took advantage of a mobile dyno at a local car show and added a little more boost with each pull. I turned on tune analyze live in tuner studios with each run trying to smooth out the fuel table. I made sure to WOT at 2k rpm for turbo response data. I have the waste gate actuator on the efr6258 set at 11psi. At the end of the video you can see a datalog that shows the WG opening at 3300-3500rpm. I tried to gradually increase boost from 3500-5700. Then do a quick ramp from 5700-7300. All to save the stock NB1 6spd transmission. Driving home from the car show was a bit wild. 1st and 2nd gear are difficult to shift fast enough without banging the gears and causes wheel spin even with the 3.63 diff. Boost by gear would be sweet. 3rd-5th feels properly quick. One of the local mullet kids driving a straight piped yee yee truck wanted the sauce. We left the stop light and he had his hemi screaming for the muffler back. I eased up to 3rd and gave it all the Uncle Ben's. YEE YAA LATER!
Car Details
1997 STO Edition 1260
Bought the car with a stock engine, NB1 6pd, 3.9 torsen, and BEGI S4 turbo kit in 2015. Eventually the thin wall tig welded turbo manifold cracked to pieces along with the downpipe. The clear coat was pealing as well. Over the past 6 years I had it wrapped in 3M Atomic Teal, built the engine, installed 3.63 Torsen type 2 from the UK, installed xidas coilovers, and Konig Hyperchrome Countergram wheels wrapped in 205/50/15 Continental Extreme Contact Sport. It's been to countless track days and autox events. Love this car.
