TT on a 11:1 compression ratio engine is dangerous.
I personally wouldn't try it, unlees it's 9:1 or lower.

Engine timing is crucial.
Also no one has been able to crack the VVEL, that could be another issue.

The VVEL system has been out for over 3 years without any issues except for Valve Overlap in terms of boost. The rods (weakest point on VQ motors) are beefier then the DE, Rev-Up, HR motors. It's all about the tune.

I picked up the car last wed, drove it 100.1 miles home with zero issues. The alignment was out so I drove it straight to the shop by my house. The car would not start back up after literally 3 mins after shutting down. Its not at a shop in tampa trying to figure out what is wrong, NO check engine, No codes, still so lost why its not starting.

Car starts up for 3-4 seconds at idle and shuts off as soon as you hit the gas. Sometimes it will rev and then shut down.

As you guys can tell im kinda over the car already.

it starts everytime, just wont stay on longer than 4 seconds and if you hit the gas it will 90 percent of the time shut off or rev with no problem and then shut off

yes! WOW it was a huge relief that it was something simple but I still had to pay for man hours on the car. Owell, its done its back in my garage for the first time in almost 4 months.

Car drives like stock, very smooth until your in boost and all you hear is open wastegates. Its running on the factory wastegate springs so boost is max at 5lbs.

Im going to drive it alittle more this week but so far its very smooth and fun to drive. The clutch is loud as hell but I guess thats something ill get use to.

Well todays update is a solid one, drove up to Z1 lastnight and had a few issues getting to them. Long story short I was able to get to them and had ZERO sleep.

Today we retuned the car with over 50 dyno pulls tunning the car from 400hp all the way to 525 at 11psi. Airfuel is 11.2 solid throughout the RPM band. Low boost setting is 8 Psi 469 hp sorry dont remeber the tq. 11 psi setting will be the high boost and the final numbers were 525hp/455tq

Im going to dl pics and videos when I have a chance

BTW Z1 guys were amazing! They were slammed getting ready for the Z1 nats and worked on my car like as if it were gold. Everyone there was a pleasure to chat with also.
THANK YOU Z1
