So far a 1.45 on a 100 shot and a 4K stall from Fuddle...
What I would like to know from you guys, is what stall and at what RPM's you have the N20 activating at.
The time above, I had it set at 3700 RPM's and netted the 1.45 with a 255/50/60 MT DR and my 10 bolt with 3:73's.
The last time out, I bumped it up to a 150 shot and I lowered it to activate at 3300 (or maybe 3200). But I added a 3:89 MWC 9", NANO bottle, and went on 26" ET streets and only netted a 1.55 60'.. So, I wonder if lowering the activationthat low actually hurt the 60'.

The 26" ET Streets are why you lost your 60', not the activation RPM. With a 4k stall converter, changing the activation RPM won't really matter because the RPM's will shoot up to around 4500 anyway as soon as you floor it. I used 27" ET streets before....I hated them. I changed to a 275/60/15 (28") M/T Drag Radial and my 60's went from 1.52 to 1.37.

Well, I guess its time to get a 275/60/15 DR then... Is that what you suggest? These 26" Et streets barely fit as it is. I dont have adjustables to tighten up the rear. What DR is equal to a 26"?
I was hoping on a 1.3X 60 on an ET street and was mad due my 60' went to ****..
Even on motor I was low 1.5's consistent with the old set up.. Now, the 2 runs I ran on motor this year on the new set up, cant even get into the 1.5's.

Good luck finding some M/T 275/60/15's; been looking for a set for my Mustang for weeks (and I work at a speed shop that DEALS Mickey Thompson). You would have no problem running a 325/50/15 though.

You can fit a 28" tire on any f-body. It's as big as you can go without cutting anything. If you have the car lowered, you'll have to roll the fenders. Other than that, I would definately try a 28" drag radial. The 325/50 is also a 28" tire, but it's more than you need, and you will have to take a big f'n hammer to the inner wheel wells for it to fit. You can put the 275/60/15's on an 8" or 10" wheel. They will have a better contact patch when mounted on the 10" wheel, but I had mine mounted on 15x8 Prostars and cut consistent low 1.4's, and went as low as 1.37.

Like to see this as I would say alot more things slowed this down other that ET Streets! Hard to believe that a 26" tire in ET Streets vs 26" Drag Radial would see that big difference in 60 ft. Could it be with 26" tire is was spinning then u put on 28" tires which change final drive ratio it hooked. Remember height is more important than width! Just my 2 cents. Lets us know when u put on new tires on so we can see!

my best 60' ever was a 1.63 60' on 26" et streets, Spraying 150, 3,200vig and stock 3.23gears.
the car hooked good, I had madman rear suspension pieces(everything other then stock TQ ARM) and QA1s up front. its kind of sad, the car just came out of the hole soft but screamed on the top end. I was only pulling mid 1.6s and running 10.8s @ 128mph with 575/611 to the ground. A larger stall and 3.73s would have really helped me. I should have at least been in the low 1.5 10.6 area
