not sure what you were making for power before compared to now, but ya probably need to go to a 28 inch tire now... and don't try a 28 inch radial, I'm messing with them now and so far they have been a waste of time

I have the 28" radials and haven't had alot of luck out of them either....but on the other hand, I have seen some bad cars dead hook on them almost every pass.

Oh I know, hence why I bought them. Sonic Snake on here's camaro with a 346 h/c and 150 hit 60 foots in the 1.3x range on them... I'm making about 80 hp more then he is on motor, and I haven't hooked for crap with them yet.

Granted my car's alot heavier, and we found a couple suspension fubar's over the last week, real drag swaybar also added as well.... but so far I haven't liked the radial one bit.

28x10 et drag will be the next tire unless I see some improvments this weekend.

I hear you...I will be swapping also unless something changes. My buddy has a 93z with a 396 and has the 325s. He hasn't gotten them to hook yet either. So far, I am not impressed.

I'd seriously like to know what people with good power (550+ at the crank) are doing to hook on the raidals... some people do, others can't for the life of them, but run great on a bias ply....... there's something that some people have figured out wether it be on purpose or not that makes the car work... but I have no clue.

Hopefully the 30 lbs out of the nose and a couple suspension fixs/upgrades this week will help my situation out.

Pewter have you talked to anyone else that runs don's setups that is 60 footing like mad? There's got ot be another one of his guys running a race tire setup....

most are autos though

i think most of it is i cant dump it any more and have to slip the clutch for starters and might stiffen the rear a tad more after looking over the videos its still squating a tad and the axle is coming up instead of down . plus track prep was non existant . i was hoping for some answers on shock settings and tire pressure just no answers really yet. idont wanna go to low on pressure either as the car is still a pig (3600+, scales were closed)
just looking for different opinons on stuff that has worked for others . i have a few more things to try myself but more info /help is always good
im gonna hit some street nights on the nittos which will help with slipping the clutch to launch

you could be right... but look @ guys like smokin01ta, he was running 10.2 with his car and was dumping the clutch at 7200! He was running a 28x10.5S ET drag though.... I have a feeling your current launch technique will work if you put enough tire under it. Might have to get some weight out though to stop the inherent bog that will probably occur when the nose starts dropping back down, but it should work.

Another thought, not sure how close you are to the rev limiter, or if you are gonna stay n/a or not, or are willing to do what will need to be done to fit a big tire like a 28x10.5S et drag, but if clearancing is in the realm of acceptable for a tire like that, you could probably go to a 4.30 or 4.56 gear too with that tire, to get the ratio back down so when te tire does dead hook the bog will be alot less of an issue. If you're gonna stay n/a a 4.30 or 4.56 would still be fine.

staying N/A and i do not wanna cut up the car for 28's its 95% street driven. im not gonna hack it up for a few races a year . i know more tire would be nice but i still think i should be able to get the 26's to hook pretty damn good just have to learn not to shock them so much and dial the suspension in for this setup .

put the fronts on 2 if need be, until it's hooking keep going with it. Tires could go to 12 psi too, that might help.

Where's the pinion angle, and what tq arm is on the car?

tq arm is stock , nothing else fits good with a 9" w/o hacking the floor apart
but i do have the relocation mounts and there on the lowest setting
i had the shocks softer on the last setup and 2 was to loose it was bunny hoping real bad . i found 3 to be a good medium plus its stiff enough to not slam down after / between shifts

that's right it will toss weight around as you shift... maybe an r series up front ot slow down the compression to stop some of that, or a double adjustable to stiffen up the compression would fix that as well

You've probably outgrown that tq arm, I'd look into getting something, mod the floor if need be it's not gonna be seen really under the carpet. I had to beat a small dent in the tunnel to clearance for my bmr one, not that much really and even thru the LW carpet and no rear seat I can't tell it was done. A stock style tq arm, and a BMR crossmember would be good, it will give you some adjustment at the front of the tq arm too, saves a couple lbs as well, nevermind getting the tq arm mount off the tranny, taking all that load off the tranny mount and whatnot.
The relocation brackets should help too, no more wheel hop etc.etc. You'sre still running stock springs up front?

seen plenty of cars running the stock arm and hal's springs up front.

if it was an all out drag car id just order up a madman tq arm but again its mainly street and like i said seen plenty of cars on the stock arm hook and hang no problem . just have to get the rest of it dialed in now
