Cut the 60ft time?!?!?!?!

[Fox Slaughter]

Alright I am pulling horrible 60ft times. 2.4 to 2.5 range. Best I ever managed was a 2.3x.
I had bald BFG street tires when cutting those times so I got newer BFG street tires with a lot of tread and still cut the same.
I attributed it to when I had the tires mounted they pumped them to 34psi! Factory says 30psi. So when I came home and found that out I dropped them down to 30psi.

So I have a few questions.

1. What is a good tire pressure to run for good traction but good street ability? I don't have a trailer so I have to drive the car to the track.

2. I have Poly Lower Control Arms and relocation brackets. The car is at stock height, with stock shocks and springs. When I put them on I just put them in the lowest hole. I just measured the angle on them and its 7*. I was reading you want about 2*, so I am going to move them till I get 2*. Is this a good spot degree for them?

3. What would be a good pinion angle? I can't change it now because I have a stock torque arm but I would like to know for future reference. I am finding about -2* is a pretty good angle.

The 60ft time is killing me. The best I've run is 13.87 at 103mph with a 2.3x 60'. I trap 102.x - 103.x every time but my run high 13s to low 14s.

Anyways I've been busy with training so I haven't been on lately.

Alright well I just moved my LCA to the highest hole and I still have like 4*. So its a lot less than it was.

Pinion angle to my best guess is 0*. Its hard to read it under there.

If I get an adjustable torque arm and adjust the pinion angle -2* would it affect the LCA angle?

[killa89trans]

it seems like it would adjust the angle because your adjusting the torque arm and all.

Until you get better rear tires, you're just spinning your wheels. I know, its a really bad pun, but its the truth. No street tires will hook up these cars. Slap even a set of Nitto's (drag radials) and you're below 2.00

[Fox Slaughter]

Well I want to get some MTs at sometime but I need to do the rear end first.

My plans are once I'm working again are to...

Reroute the fuel and brake lines, tuck up my true duals, then rear end.

[Nocooler]

Pinion angle has very little to do with traction on a torque arm car.

Just get some nitto's or toyo drag radials - you'll be able knock an easy 2-3 tenths off the 60's - and put you in the low 13's.

I've cut 1.7s with my 555rs.
That was stock height in the lowest hole with ~ 18psi in them.

[my95z28]

Honestly, practice. You're chasing suspension issues trying to get the car to hook, these cars bone stock with a good launch and street tires will do a 2.0 60ft. Are you bogging off the line or spinning? I like to launch right around 3k rpm, and then change how quickly I let the clutch out to get a good 60ft time. Using this method and an aggressive slip of the clutch I went 1.95 on bald nexen n3000s

[Fox Slaughter]

It spins. I would rev to 2000 slowly let the clutch out under part throttle then when I put the throttle to the floor it would just spin. When you slip the clutch do you just rev up on the line, light turns green hammer down and let the clutch control your wheel spin?

I just posted this exact same thing. I also have worn BFG's, getting a 2.1/2.2 60 ft. time, trapping at almost 110mph, and hitting 13.2-13.4's. Definitely need some sticky tires.. slicks or DR's. Better rear shocks should help.
I read an article on MM&FF that said a Drag radial should run between 14-16psi on 10sec. cars, and for slower cars(like ours) right around 18 psi is perfect. Most tracks(all that I have seen) have compressors on site, so put 25-30psi for normal driving, when you get to the track, bleed them to about 18psi, then pump them back up before you head home. But you could drive on 18psi for the ride home and be fine.. I've done it. Air pressure is a big deal, I've seen it cause a couple tenths in a 1/4 mile. Bottom line, 14-18psi is what you want. And get some real drag tires

[c0ncEpT]

Lowering the air pressure isn't going to do much of anything anything in a street radial.

Get a real tire. A bias ply like a ET Street or even an ET Drag would work best for you.

[gary]

Tires!!!!! Get a set of ET Streets and run between 15 and 18 psi. I can run a 1.60 60ft with a soft launch. And that is with the pinion angle in stock position

[ryanwarby01]

I have ET streets and love them. They make a huge difference. I didn't change my tires until I had my rearend squared away either.

[c0ncEpT]

I have been 1.6x with my 10 bolt and plan on going faster.

I will agree an M6 is much harder on the rear than a stalled auto. If you plan on racing it you will need a rearend soon.

[Fox Slaughter]

Hm sounds like the consensus is drag tires.
