I usually shift at 6200 rpm.

Thinking about going with upr tubular a arms up front and coil over springs. And maybe try the team z rear drag spring.

My ultimate goal is a 10.50

I'm not sure what the car weighs I will half to try and find a scale.

That sounds like it's gonna be a solid build though.i thought about getting Ed to make me a custom cam to swap in.but I'm gonna stay focused on suspension mods for now.

I think 600 is a realistic goal.

At that mph, your 60' could realistically be in the 1.4 - to low 1.5 range - it's easily a mid to high 10 second car. What tires, and are you spinning on launch? What rpm are you leaving at and are you dumping or slipping the clutch?

I'm using the Mickey Thompson pro drag radial.275/60/15
I'm launching at about 2600-2800rpm and dumping the clutch.

The car usually dead hooks.on one of my passes the exhaust came loose and didn't have time to fix it so I just dropped the exhaust system and ran open headers on my last pass.which resulted the 127 trap speed.i have never trapped that high before.

I think if I can power shift 1st to 2nd it could help my 60ft time.

The guy next to me ran a 6.93 at 99.54 for the 1/8 and 10.92 at 120 1/4 mile. It was a little Chevy s-10 pick up truck.i have no idea what his combo was.i will try to post up the time slip when I get home from work.

That seems way low to launch. Assuming your cam matches the Box R, you'd probably need to launch around 5,000 rpm. I know, that seems violent. And it is. But without the benefits of a converter multiplying torque and softening the hit, that's your best bet for best times. I'd switch to a bias ply tire - that much violence with a radial will start to break parts.

What was you mph before you pulled the exhaust?

Either way, you have a stout, enjoyable combo. Good work!

EDIT - Treed on the bias tire thing... I was typing while Shifter was posting!

I agree with the bias ply comments. Its hard to be consistent with radials and a stick. I added a 2 step and qtp's which helped alot.

Are you still running a stock k member then?
I just switched to wilwood street 11" front brakes on the fox spindles. That was good for 34 lbs. Tubular a arms was another 16. I'd bet a tubular k would be 25 and coil overs another 10 for 85 lbs total.
What are the details on your engine? Do you have a build thread?

Got any more info on these? Model number, cost, can you autocross with them, etc...

Thanks!

I do have a upr chrome moly k-member but kept the stock control arms.

wow 34 pounds on the brakes huh.im gonna look into those.
are the bias ply tires stable on the top end? I want the car to feel safe.

do you guys think I would benefit from any type race fuel? static compression is 11.3:1 been running pump gas with no problems.

My car was no better on bias than radials with a stick in it. Actually, the M&H radials were way better than the MT ET Street bias drag tires.

I never got to try Pro radials on it with a stick, but with my little turbo and auto the new pro radial were in the 1.2's and can handle the shock of 25 psi boost on launch. I'll see how they handle the bigger turbo soon.

I would think you could autocross with these as good or better than with the stock brakes. I just wanted to shed some weight and look good doing it. You cut the caliper brackets off in the process so there is no going back.

you are on your way to tens, mph shows you have the power for solid to mid tens. Keep uping your launch rpms till you start having traction issues. as long as you are dead hooking you don't need a different tire, the radials will be quicker as long as they keep hooking. the higher the launch the quicker the 60', you can typically expect double the gain from the 60 to the 1/4 mile time. I found a lot in mine through suspension. you can always come to the dark side and go automatic, most come out with a quicker combo, not always, but usually.

..5.95 @ 115, 1.30 60', naturally aspirated.

Stiff wall slick and upping the launch RPM will probably give you a 10.70 first time out.

Thanks for posting the detailed info. I would love for someone to make an aluminum bolt-on caliper for us.

The issue isn't hook, it's that radials + stick = broken parts. Plus they don't last as long as a bias ply or stand any chance of recovery once they do spin. But really, the issue here is breaking stuff; that's all I was trying to say.

The broken parts result of the radials + stick equation only happens when the clutch is aggressive enough to pull rpm down substantially on the hit.

With a proper hitting clutch, the equation changes to radials + stick = quicker pass.

Thanks for the feedback guys. The clutch is a centerforce Dfx.i bites pretty good.

And I figured the fatter sidewall tire would help absorb some of the hit.
But so far I like the pro radials.never ran a bias ply before.

Next time out I will try to launch it at a higher rpm.i hope I don't break anything because I drive it to the track and back home.car is a blast to drive around with street tires. Do you guys think there would be any benifit going to a larger mass air meter?i have a 80mm now was thinking about going to a pro-m 92mm.

I think you would be amazed with the brakes that Rian posted up and good set of stiff walls. I run both, and they both helped Et. Starting at the 60 foot and multiplying at every timing point to the strip. In fact my 347 pretty well matches your MPH and betters some of the ET predictions a few of the others have given you. I pretty much think you will go up quite a bit from there. And of course the camming and gearing thing. I noticed you still have a booster hooked up and FTI has done a really good job for me in that department.
