Surprising day at Test and Tune yesterday. With the Gt42, if you miss a shift the pass is effectively over. Since it didn't want to shift into second over 7500, I decided to try short shifting 2nd gear to get it in and was surprised with the result!

Short shifting the car caused it to take 5.2 seconds from launch to see 30+psi

Lots of room for improvement basically everywhere. As it stands, it would probably go faster with the smaller turbo as the car sits. Would have been really interesting to see what the 67mm would have done with the 26's

More to come.

It will be good to see you! Test rides available :)

In the last few weeks, I wired in a BCS so I can add duty cycle though link to help keep the boost up top. While out testing the new controler, I lost my clutch pedal. Had to limp home rev matching!

Hydraulics checked out. Ended up being a broken pressure plate. Found a "bad twin" on craigslist I made work with some "creative adjustments" lol. More on that later.

So-went to a local import day at the track. same boost as last time out, just some duty cycle up top in 2nd, 3rd, 4th. It was HOT. about 90 deg.

Leave easy 1.7 60- have my BEST 1/8th mph 122- it holding boost..things look good- then BAG. Torquesteer?? Shifted 4th and kept on rollin' Went another 9.7x whis is remarkable considering I GRENADED my T case- in 3rd gear! LOL

I pulled the T case and Driveshaft and was prepared to race in FWD, but a full oil down delayed things long enough that packed up and kept drinking beer.

We had fun, and she drove into the garage under its own power, so no complaints here! Doubt I will be out again before the shootout since I have such a hectic work schedule next month.
