New personal best bolt on mph 126.55 +300 DA
 

Only got a few runs in today and my best 60 was only 1.60 so I didn’t improve on my 10.85. In some -500 or better DA and a mid 1.5 60 I think it’s a 10.7 car now since I added the pulley. DA today hovered around 0 and it was +300 when I checked it on my app at the track after my run. Temp upper 50s. Humidity was low around 35%. Just a very slight headwind maybe 3 mph

I am thinking the ATI UD pulley gave me an honest mph and a half tenth or so. The car has never done better than 125.3 even in slightly negative DA until now. I trapped 126+ two times today and one other run at 125+.

Supposed to warm up so not sure I’ll be get that 10.7 until the fall. Maybe snowblind can be the first.

Was the slower 60' due to wheel spin?

Not trying to rain on your parade, but wheel spin off the line will actually increase your mom, since you are essentially increasing the distance traveled.

Either way nice times!

It didn’t feel like spin but it’s possible. On the 1.60 probably just didn’t flash it hard enough. I’ve only ever cut a 1.5 60 ft two times. You got to do it just right. I really don’t think i spun at all

I have piles of slips and plenty in the 1.6 60ft range and the car has never mph like this. But yeah I agree spinning can increase mph at times.

For those interested I’d say it’s a worthwhile mod imo (the crank pulley). Which is the main reason I made this thread

Great pass ultra.

Awesome pass!! That's really moving!

Congrats man

Thanks everyone

Thanks. Got some logs for you to check out! I think it’s just about dialed in. The 1-2 shift actually came down a bit too much at 6350. It was 6750 before. Rest of them are 65-6600.
Other than that I guess we’ll see what you think.

Solid pass bro. I'm sure you'll be at it next week too.

Thanks

I work next weekend. And the weather is looking like 65 on up after that. So who knows

Looking GOOD!

Thanks. Have you made any more progress with yours?

You must run 9s SBE NA!

126.55 is just nasty!!! Damn good job!!

Nope, I actually broke the weld on the ring gear to diff a week or so ago...just messing around the street. LOL. Loud clicking/knocking noise from diff, right after a nasty 3 to 4 pull vs. a GTR. :)

Funny I almost got into it with a gtr on the way home from the track. Too much traffic. Figured if he was stock I could put up a fight

You thought about doing the 3.27 gear? It would be a good match for your tire height and mph. Just about perfect actually . At 7300 rpm 5th gear with 25.8 tire height is 135 mph. Could always add more tire if needed.
