lol if you saw me you probably would think I do. I weigh about 145. I weighed the car with no jack, spare tire, test pipes and x02 exhaust.

OP: Are you planning on dynoing the car anytime soon?

awesome!

tons of people never thought it was possible
...glad this showed them up

OldManZ350, you're probably crossing the line at the bottom of 5th gear, ever consider a shorter final drive so you'd be at the top of 5th gear instead?

I did have that problem with m/t 275/50/15's (26 in tall) ran 12.010@118
changed tires to m/t 275/60/15's (28 in) tall ran 11.856@116.76

With the 28's I cut .277 off my 330ft and .263 off my 1/8, but lost .110 in the second half of the track. It also was very humid and higher dew point. Car runs best in Dry, cool weather. I will run 11.50's-11.60 with this setup.

Now I waiting for someone to Correct me ( 275/50/15's are really 26.1 tall) and Hijack the thread again. haha

so with the 275/60/15's, you didn't have to shift to 5th? or did you have to shift to 5th every time regardless of tire?

again, nice times

With a 28" tire you don't have to shift to 5th..275/60 is a 28" tire

thom000001

6700rpm redline, with 26in tall tire, and stock 3.5diff I was going through the traps banging the rev limiter in 4th at 117mph all day (on pumpgas)......Was at the point that if I shifted to 5th it slowed me down a bit.

thats all changing this season woohoo

Tom...are the SP guys running the 3.5 diff

thom000001

yea they are running a stock 6spd 3.5diff but they have a slightly higher redline

I have a 3.3 vlsd sitting on the garage floor waiting to go into mine. And we'll be doing cams too (help the engine breather a little easier).

Tim...any plans of changing your diff to the 3.3. I remember a guy that raced with me @ Bradenton and he went with the 28" tire and a 3.3 in his 6mt and he had plenty of 4th gear left going thru the traps. I wonder if any of this makes a difference on a SC Z opposed to a turboed Z

thom000001

Don't know if the centrifigul SC's make enough low-mid tq to warrant a lower geared diff like the turbo's due. But I could be off for Tim's setup.

nice. brembo owners get the shaft for dragging. At least MT makes a 275/55/16 DR. Good to hear your JWT clutch is working out. Mine just slips when i try to launch.

11.5 will take some more seat time. i'm sure you get it though.

My car will go 11.50's -11.60's before summer, every time I take it out to the drags I run another best time. The car has only 13 runs on it, and I only run it 2 or 3 times when I go.

With the 26 M/T's and 6600RPM I was hitting the rev limiter @ 113 in 4th gear and had to shift into 5th just before the traps.
With the 26 M/T's and 7100RPM I was hitting the rev limiter @ 118 in 4th gear and had to shift into 5th just before the traps.
With the 28 M/T's and 7100RPM it will go 130 in 4th gear before hitting the rev limiter.
So I have plenty of room now in 4th Gear with the 3.535 Diff. Trap RPM is 6300-6400. A 27 tall tire would be perfect for the setup i have now.

what are you tuning with?

Those are awsome times. Just one question. If you're reving to 7100rpms with a 2.87 pulley, aren't you worried about overspinning your blower?
