Thanks man!

And now that I am back at a computer I want to apologize to everyone for posting every 2 seconds like a teenage girl on facebook.

I went to the track alone and had nobody to talk to

Now... what to do with 9 GoPro videos that are upside down?

OK this will be my data post.

60', 1/8, MPH, 1/4, MPH

2.188 / 8.067 / 102.31mph / 11.894 / 130.20mph - VIDEO HERE
first pass, i suck at everything, running 11psi. I check tire pressure and drop it a little.

1.958 / 7.677 / 103.43mph / 11.446 / 133.37mph
do everything a tad better, might have tried adding boost (going about it slowly because settings on dyno and street are different, and i dont want to go too high)

1.913 / 7.574 / 103.80mph / 11.336 / 133.90mph
same thing. think i dropped tire pressure a couple more psi

1.858 / 10.876 / 54.24mph / 18.448 / 63.06mph
i turned up the boost and made about 11.5. I also got the tires heated up a little better and it gripped more, causing me to bog. But still got better 60' that previous. Unfortunately when the boost came on the extra power was enough to light up the rear tires. I got locked out of 2nd and drove nice the rest of the way. After this pass I went into the boost controller and set the boost by speed to keep the boost level below 60mph to about 10.5psi and leave it there the rest of the night.

2.049 / 7.607 / 103.65mph / 11.308 / 133.41mph - VIDEO HERE
nothing to see here really. decent pass with crappy launch. Raced a vette. This vette and I had indentical 60' and 1/8 numbers, but his RT was .5 quicker which is why he started out ahead. For some reason he let partly off just before the 1000' otherwise i probably wouldnt have passed him... his numbers on other runs were very close to mine. Notice that I ran out of gear just before the end and didnt have time to shift into 5th. So the 28s with stock final drive was not able to keep me from topping out 4th before the end. Probably cost me a tenth.

2.045 / 7.572 / 104.61mph / 11.323 / 123.59mph
im picking up mph as i slowly bring up the boost... between my crappy 60' and a little more boost (i think i hit 11.7psi this run) i gain too much mph and i run out of 4th well before the end and attempt to get into 5th but miss and coast.

1.896 / 7.502 / 102.33mph / 11.226 / 133.78mph - VIDEO HERE
A mediocre launch, good enough to bring the ET down a little. I take too long getting into second. I see that my time hardly dropped despite the run feeling cleaner. I check the peek hold and my boost was lower on this pass. I turn up the boost a couple notches trying to get the damn thing to run my 12psi.

1.891 / 8.126 / 73.94mph / 14.828 63.04mph
This is where my clutch problem becomes obvious. The engine is just climbing to redline but the car isnt coming with starting in 2nd gear.

1.719 / 7.327 / 100.45mph / 12.708 / 66.31mph - VIDEO HERE
And this is the run that would have been it... a low 1.7 60'... my 1/8 mile time, despite slipping and staying in it, is 2 tenths faster than all my other 1/8 miles... and 2 tenths was what i needed. The better launch brought my MPH down so I should have been OK to finish in 4th. GRRRR the car just stops pulling towards the top of 3rd so i let out and touch the brakes... and yup drove through a 12.7 LOL.

I let the car cool down for about a hour and try again. No luck. I make 2 passes and its worthless. I lost one of the timeslips but one of them was:

1.847 / 7.598 / 93.43mph / 12.649 / 83.21

And the car has trouble driving up the trailer with the clutch slipping so bad.

Man I wish we could get that many runs in in a night here. You might get 4 runs for 5 hours of your troubles.

What did you have in there for a clutch? I would suspect its just the CSC.

Good to know the engine can take that torque in its stock form.


Also you were so excited you couldn't sleep hey? Them are some late timestamps on your posts

I see you are running 28s on a 15inch wheel? I have 18x12 wheels sitting around and thinking about 345/35 MT street radials once i get the car back. When you had the 18x12 set up,did you ever consider running a 345/35 radial?

megalapagas

DAMN!!!! That Feel Of 2nd & 3rd! Man Cant Wait till I'm boosted! Shooting you a Pm Phunk!

Yes, but I started with the 315/35/18 because the 18x12 +20 wheels were new to me, and i wanted to go on the safe side. The plan was to run the 315/35 and measure off them to see if I could go larger.

Turned out to be a wise decision... the +20 offset was too aggressive to go any wider than the 315/35 (with my like .5-.75 negative camber). Otherwise I am sure larger tires would have fit. I would go much more conservative on the offset and then use spacers to fine tune it. Thats what I did with my 28s since I wasnt sure what offset to use with that height... turned out what I got was perfect good looking fitment with some 10mm spacers, which is fine by me since I have ARP extended studs.

Still to push through a twin clutch setup is impressive. That car must be a absolute beast now.

Now lets see 13psi! lol

I planned to spend the weekend settling back in after the last couple days of craziness but this morning my grandfather passed away and my father cannot drive due to a recent eye surgery... so looks like i will have my hands full this weekend. Perhaps next week I will have a chance to look into the Z and decide if I am going to make another attempt this year or just leave it down for R&D for a while.

Not sure any words can adequately tell you how amazing all your numbers are. Great job man!!! Thank you for sharing with this community and also being a trailblazer to see how far these cars can be pushed. Look forward to seeing you get in the 10's!!!

Funny how now that we're seeing more cars eclipsing 600 the goals keep changing of what we want.

That said, I'm still mad E85 is just not readily available here.
