'20 GT500 Deep 9's 1/4 Mile

[LostM]

Had a decent track day last weekend. TCM tuning has finally become available (partially) which is what I needed to start taking advantage of the upgraded SSP DCT clutches. Prior to this, and even still somewhat, the clutches are doing such a good job, it was pulling RPMS down causing sever bog. Previously on launching at 3200 rpm, car would bog to about 700rpms, and then on the gear shifts, drop by about 800 rpms.

For now, thanks to HPTuners, the launch is about on point/ back to OEM levels, and the gear changes are only down about 400rpm. Plenty of room for improvement as more tables are opened up

Unfortunatley, belt slippage became apparant immidiatley. My combo should be seeing 22-23psi, but was erratic and moslty 17psi through the runs. Ill be hitting tracks again in about 2 weeks, and the boost issue should be rectified. Car is 100% full weight, and probably even over with some of the additions. at SCT Bradenton, car weighed in at 4390 with me in and full tank

9.24 @ 148.56! Congrats! That is one hell of a quick GT-500. My only complaint is that you didn't post a video. I wanted to get my adrenalin pumped up. LOL.

Man I wish I wasn’t so poor and could afford a car like that. Must be nice to have real money. I’ll always be one of the poors.

Ken has these cars rolling pretty hard, I've seen some of your stuff via Jason on FB.

So what are the limitations of the stock DCT clutches and dare I ask what the upgrade runs on that?

Wow. 150 mph. That’s hauling the mail.

kens got them rolling thats for sure. I cant speak on what is/isnt available in the tuning thus far, beyond my expertise, but i know he said we can hit my clutches hard at the next track day when prep is better. as for the rest, he said he just needs more tables to play with

stock clutches can hold just at 800rwtq- dont quote me on that #, so the issue for everyone is finding the fine line to keeping dct happy and maximum power applied. Ive made and held tq that the clutches are rate for- on the dyno- well beyond stock limitations. Right now its a waiting game. Even after im gonna navigate slowly as i dont want to break anythign inside the trans

Wow. 150 mph. That’s hauling the mail.

it was consistanly 151-153 before the clutches wore in and really started grabbing, once its sorted, should be that or dare i say a tad higher

Nice times. I would have loved to see some videos as well, but we will just have to wait for your next track outing to see some videos. Thanks for sharing your progress. Any under hood pics?
