I been having some issues with the new engine combo and traction, if i foot brake it seems to be ok, most of the time, but when i try and use the 2 step, it will start and pick up the front wheels and then come right back down and it feels like it is spinning the tires. i am at 1.36 sixty foot, have i reach the limit with the springs? i have Calvert shocks all the way around. Thanks
 
I definitely made an improvement in 60 ft. with Calvert Springs
and Bars. I also saved some weight. I use them on all our Stockers
and even my 318 Superstocker and 9 Second bracket Duster..

Also some adjustable front shocks make an improvement over the
Calvert Shocks once you are into the 1.3s or faster and have some
issues.

However, 1.36 is a GOOD number for a high 10 car or even a mid 10 car!

Thanks John, i am in the low 10s at this point, and did that 60 foot with a 4.30 rear gear.
 
According to the MP books, that’s about the area they say is the SS springs to be about there limit. It MAY be possible to week out a little more.

Are the front segments clamped and the rear bands that hold the spring leafs together cut off?

1.26 is definitely gettin some.
Nice work.
 
Do you have the Calvert(Viking) 9 ways on the rear? What setting are they at? What size slick? How much pressure? It sounds like the tire is hitting hard like is supposed to but doesn't stay on the track when it unwads. Shocks: Tighten compression so the car stays on the tire and doesn't bounce up. Tires, try more pressure if shock adjustment doesn't do it. I couldn't get my 12x29 slicks to hook at marginal tracks, so I went to a 14x32 slick and it hooks everywhere now.

My 10.0 car does 1.40-1.42 60 ft but makes up for it with top end.

I have the fronts clamped, still have the bands on the rear section, i am at 1.36 not 26. Thanks

Do you have a video showing a quartering view from behind the left or right side of the car during a launch?

Yes the Calvert 9 way, set at 5, 9 inch radial at 20psi,
 
Can you adjust the timing to come in softer and gradually ramp up? Essentially, soften the hit and build up to full power. That turbo car is doing similar stuff with boost control (and I’m sure traction control with driveshaft speed), and really dialed chassis setup of course. Some DA shocks can help to as I don’t know that the Calvert shocks are.

Yes! 1.36, the “.26” was just a fat finger reply mistake.
The removal of the rear clamps is a trick. IDK if it would help you or not. I’ve never been where you’re at.

Just thinking out loud with me replies.

Do you race in a class that requires the 9" radial? I'm thinking that more tire will solve it like it did for me. Ì would try a 12" bias ply and maybe 1 or 2 inches taller to slow down the hit a little. You would need to turn those rear shocks to 7 or 8.

Definitely the shocks are way past their limit.

IMHO a single adjustable shock is worthless on a mid 12 second street car and maybe 11.50’s with a sift leaving automatic.
 
The Calverts that we used to run some years ago on the front were not adjustable
at all. However, the back shocks were adjustable.

I do not know if the has changed since we ran the front shocks.

John Calvert Sr. is a brilliant racer and engineer and him and his family has kicked my Butt and my
Boys more times than I can count since the 70's.
 
I guess it's possible (not probable) you've reached the 60 ft limit, but certainly you've not reached the ET and MPH limit.

You'd have better repeatability using Cal Tracs or something similar. You could pick up some ET at your speed as well. But as others have pointed out you'd do well being familiar with how your entire car reacts with video and then of course a means to adjust responses locally.
 
No, I don’t think so. Reaching the limit would manifest in spring wrap or collapsing the spring on the hit. My guess is with the 2 step, you are topping out the front suspension too abruptly and upsetting the tire. Slow the nose down just a hair. Does it chatter the tire? In all actuality there are better bolt on setups out there. Move away from using the spring to control the tire to using the shocks.

My old car was deadly on super stock springs off the foot or the brake
Weighed 3350, uncut, untubbed 70 Duster, full backseat interior.
Typically 1.34 60 foots, 9.80’s then 9.50’s after couple of motor upgrades(W5)
So, IMO, you’re nowhere near the limit. I ran cheap CE 3 way shocks on all 4 corners, no snubber, no clamps.
Car was truly deadly, I remember one dead of summer event car ran 10.01 5 passes in a row.
28 by 10 quick time pro tires

No room for more tire, stock tubs, and i do not plan on cutting it up.
