First of all, yes I have done a search and read all the stickies.

I look at the cam only times and see 60 foot times in the 1.3 range and want to get there. I feel like I have all the ingredients including afco DA's all around, new slicks and fully adjustable and solid mounted (rod ends) suspension. My best 60' is 1.459 and that was with stock rear shocks and worn out slicks.

Several weeks ago I was able to manage a 1.460 and that was with new rear Afco DA's and slicks with about 6 passes on them. I am leaving off the 2-step at 5500-5700 rpm, and probably need to bump that up a bit.

Any advice is appreciated. I am kind of getting desperate.
Thanks

A good 60' doesn't win races

I didn't say that, someone else did...anyway
Do you have a vid of one of your launches and how much rwhp do you make?
I'm not a 6 speed guy myself but I think you may be leaving at too low an rpm.
Will the suspension hold a higher rpm launch and will it bog is what I'd like to know.

Thanks for the response.
441 rwhp
Yeah it certainly bogs. It seems to be a fine line between getting a bit of tire spin and more of a dead hook.
Unfortunately I don't have any videos.

What rpm are u crossing traps at? Maybe a bit more gear would keep u from bogging.
The bog is certainly hurting the 60'.
I wonder if 441 rwhp through an M6 is enough hp to cut a 1.3 60'?

I think your going to need more power, all the cars that hit 1.3's in that power level are auto's. I suppose a 1.39 could be had with luck, but dont expect it in the norm.

Yeah you might want to launch a lil harder if it is bogging. I have a few questions though. What is the fascination with a 1.3 60 ft and what gear are you running? What is the weight of your car?

Alex that has the black ws6 with the Cartek package on his car ran 10.32 @ 132 w/ a 1.43 60ft. He has 4.56 gears in his car. I think he is launching a lil above 6 grand not sure though.

I think to see a 1.3 you are going to need more leverage in getting off the line which means more gear, more motor or a higher launch rpm. A 346 is harder to get enough torque out of to produce that 60 in a heavy car. How light does it have to be I don't know. My buddy's T/A weighed 3480 with the pass. seat out and back seat out, no spare and 150lb driver 4000 stall and 3.73 gear and best he could muster was 1.43

Thanks again for the replies guys.
I guess a 1.38 60' is as good as it gets for a cam only car, at least that is what the cam only fastest list shows.

I am crossing the traps at redline which is 7200 rpm.

The car has 4:56 gears.

The car weighs just a hair under 3000 lbs.

I guess the next time out I will bump the RPM up and see what happens. I am just a but paranoid about breaking something.

Trying to hit 1.3x 60's and your paranoid about breaking something??

I was thinking the same thing. Something may break, sure, but the difference in shocking the drivetrain with a 1.4 and a 1.3 is pretty negligible...especially with a 6speed.

With the 6 speed, you need to leave as hard as you can.

Have you considered a GTO style gear set in the trans? That should be the ticket. I would first stop using the 2-step and see how you can manage it and if you get close to that goal. Throw in the better trans and then go from there. 2-steps are nice but with my exp working with a m6. It needs to be @ or near the limiter.

Best part is the 1:1 gear stays the same.

To be honest, if you're worried about breaking stuff, you'll never get faster. Sometimes you gotta let 'em hang out. If you're bogging, there is an issue. You need to get up to 6K on the launch or up the tire pressure.There is usually a fine line between a spin and a bog.

Agreed, and a good Bias Ply slick makes all that difference.

I think a good clutch that has some slip in it will be key.

I come out at 6,600rpm's off the 2 step. I got a best of 1.42 but 1.44 i get all day. I run a lil 26'' tire with a 4.11 gear and have a 3,700lbs car. If you care if something breaks,don't race the car bro!

You guys have more ***** than me!! I guess I am a cheap *** and need to grow a set. Mike c. Launching at 6600!!!! Good for you! Those are some good numbers. What does the car run in the 1/4?

Thanks again.

nice numbers

well 1.30's is usually a 9 sec car and hard to do on small tires and it don't mean much better 60 can be lower mph and not always better et

more RPM,
look at your 330's


5500-6K is mild, 1.59-1.62 on my 275 DR

He can just raise the two-step up higher, close to redline if he wants. I would not stop using it - consistency will go out the window, and bogged launches will be more frequent.

I definetly agree. A launch controller is as key to these 6 speeds as the tires you're running.
