I have enjoyed watching your build over the years. And I really love your most recent look and pictures.

Question: Do you know how well your car now competes (lap times) with high end factory cars such as Porsche 911 GT3, GTR's, Corvette ZR1, etc?

Thank you!

Currently I've seen 1:47's from the Latest gen SRT Vipers with seasoned drivers on the local track but they're on Toyo RRs. The GT3RS's are doing 1:46 on the sport cups. I'm at 1:50 on 200 TW tires.

Any reliability concerns or overheating issues while on-track with your boosted setup?

I used to overheat coolant and oil in 3 laps before the aero rework, zero issues afterwards. 4+ years on boost strong now!

Love it brother, you have the same problem as I do with slow speed turns. It is hard to keep the wheels from spinning if you drop to 2nd gear. Can't wait to get mine back on the track.

I watched your latest video. You were flying compared to where you were a couple of years ago.

I try to stay out of second gear if possible but it's not terribly bad once the tires get some good heat into them. I usually use it for one corner only.

It's been a long journey since I first started! Definitely a big case of too much car not enough driver!

You have a lot invested in your build Jay very impressive build indeed congratulations on all your progress!

Been awhile since I've posted but some pretty significant updates and major issues.

First preparation for Global Time Attack at Ridge Motorsports Park (my home course)

Finally got proper bucket seats and harnesses, Loved my Recaro Speeds but on track the slop between the lower and upper part of the seats was distracting.

Also added the Coolerworx shifter. I always thought the factory shifter felt great and this shifter only added to that thought.

Next installed the entire ensemble (At least the rest of it) of SPL parts.

Also upped the spring rates at the same time to account for the aero.

Do yourself a favor, remove all the arms and have a machine shop press in all of the bushings. It only ran me $200 and saved me a lot of headache.

Best of Luck on the Global Time Attack. Remember "Wall Bad, Finish Line Good." :tup:

I wish I had good luck! Incoming follow-up post

Finally was feeling comfortable enough to participate in Global Time Attack, best of all it was the first time GTA would be at my home track! Had some issues with tech but was eventually allowed out on track on the second session

Unfortunately it was the first time the Z has left me completely stranded too.
On my first session out just 4 laps in the motor blew at the end of the front straight doing 150+ (Code Brown anyone? :eekdance:)Some pictures of the carnage.

Ended up finding 5 or 6 holes in the block after pulling it.

I can't say I was disappointed or depressed about the engine, it took 5 years of 500+ WHP on a virgin block without a problem.

My issue was I was on year old scrub 275 Nexen SUR4G (Excellent tire BTW) instead of the 295 Advan A052's I had waiting to go on the next day. I was holding out better weather on day 2 as it was raining every other session all of Saturday. I was able to manage beating my PB on that 4th lap with a 1:50.775 and was barely settling into the new suspension setup. The lap was Good enough for 4th at the time but after the weekend settled 6th.

Good news is, GTA will be returning to Ridge Motorsports Park in 2021!
