New PB again!! 13.13@104.41, 1.87 60 foot (N/A 3L)

And I'm not even exceeding the tire's load rating capabilities. I'm close, but not over.
DandyMax, you just keep raising the bar! Makes me want to see if I can beat my own records. But the weather is too hot here. I'll probably have to wait until Nov to get the temps I need. Keep it up!
Wow, another great set of runs and thread!! Keep up the excellent work dandymax, I can't wait to see 12's for ya! I still remember when Sr20 hit 12's with the 3.5, and IIRC no body thought that a 3.0 would touch that N/A. Awesome job, and can't wait to see more!
Wow what a discourse! lol. But thanks for the suggestions. I cannot afford to do much more that requires money this year. So that really limits what I can do at this point... and I still have a couple hundred yet to spend on the dyno.
The car is already significantly lighter than last year 
Probably both at this point.. 
Don't really want to pull the tranny or clutch at this point but if I end up having to I will evaluate further...
IIRC by back tires are already 195/65/15 or something like that. I may look into RX-7 spares and used Metzelers as per Aaron's suggestions but only if I can get them dirt cheap. I doubt my rolling resistence in the rear is much of a factor at this point, although I could potentially lose 14 static lbs total there if his weigh 20 per side (my back wheels weigh 27 a piece right now).
I probably won't bother with this now, but perhaps when the 3.5 goes in, IF I stay N/A with it. I can still jack the rear end up some or make it solid too.
Again, money issue and what about the extra rotational mass of the wheel? But if I could fit a 10" slick on the 7" rims I have now... haha...
Already taken care of...
Don't see the need at this point unless I break them. (Back to the $$ again also)
Will keep it in mind. I am currently running better 60 foots than a few F-bodies I know that run high 12's on 1.9x sixty foots with 26" slicks. lol. But that could just be them not getting the potential out of their car... haha

And it allows you to use almost all of 4th gear effectively. A 26X10 slick on the right wheel hooks MUCH harder than the 23X8.5 on 6.5" sawblades I had when I pulled the 1.75. That's potential for ya...

RWD guys sometimes do the opposite for weight transfer, and pro stock guys who want to keep their front wheels on the ground sit their engine very low. Makes sense. Look at the hardest hooking FWD cars (GTP Grand Prixs and SRT-4), they either have long wheelbases, weight bias towards the front and their sittings sitting surprisingly low in their engine bays...

A car trapping 105-110 mph should be using 26" slicks. Yeah, they're RWD solid axle, but tire sizing is the most important part of the equation. You want as many chances on your side as possible... If Neal or Mardi could fit 28-inch slicks on the front of their cars I'm sure they would lol...
On a good track I'd say 1.65-1.70's wouldn't be a problem with the new gearing. That is getting out of the hole ridiculously hard.

Off the top of my head the main things are:
00VI swap
i/h/y/test/catback
UDP
low temp T-stat
Emanage Ultimate
weight reduction
KSport coilovers
belts: alternator only
Think that's most of it...

What's his (John's) race weight though? I think most of the ones I know are too heavy.. like 3800 lbs raceweight but yeah I've always thought their sixties could be better.
What's your opinion on my using 26" slicks.. considering I'm already staying in 3rd and not using 4th...? I should run that through my computer sims and see...
