According to those rules, his upper arms are not legal.

13.01 Traction devices are limited to hop stop bars for upper control arms on coil spring cars.
13.02 Upper and lower control arms on coil spring cars must be correct.

From his OP: In the rear UMI adj. uppers, boxed lowers stock springs and sway bar and double adj QA1s.

So, evidently, the rules have changed.

I'll bite..a little bit...L-O-L:

If you're taking timing out to hook it, I'd try the following and I'd put the timing back in:

More sophisticated shocks...I suspect what you have now isn't exactly the best for the job.

One of these if you can get away with it:

H&R Parts & Stuff rear "sway bar" (more of an ARB than a sway bar since it does not attach to the lower rear trailing arms). Link: http://hrpartsandstuff.com

Hope this helps.

Re: suspension and ignition setup need help
 

The no hop bars may allow you to get better geometry than the adjustable bars by themselves. (the rules seem to say adjustable upper arms are not legal, if they are, I wonder what else that appears to not be legal actually is?)

Have you tried changing spring rates on either end of the car?

The timing curve adjustments on the MSD to allow you to launch with low timing and bring more in will simply be a matter of testing. There may be someone who can give you a better starting point than you have, but the only way to get it dialed in is to go rent the track and beat on it, to see how much timing can be brought in and how soon.

Re: suspension and ignition setup need help
 

Leaving at idle or stalled? Not hitting the tires hard uncertain if adjustable shocks are any benefit. Do they allow deep stage at these events?

Re: suspension and ignition setup need help
 

to me, the largest handicap to overcome is the tire. ANYTHING that you can do for a "sticky" tire will be a huge help.

Experimenting with the above mentioned suggestions AND a better tire holds potential to greatly increase performance.

Re: suspension and ignition setup need help
 

and speaking of weight, ANY weight removed from driver forward is good. If you remove 10 pounds from the front, add it back to the rear.

A "ballasted" trunk lid is good. [meaning adding weight high and rearward]

Re: suspension and ignition setup need help
 

It sounds like you are running an automatic..

In this case, the rules (as posted here), leave a lot of room for experimentation.
What do the fast guys use? 400?, 2.20 low gear?, 350? ..Aluminum drums (I'll bet they do..How about a Powerglide?

Converter rule is wide open..Again, what do the fast guys use?

Re: suspension and ignition setup need help
 

Yes. That was last summer at englishtown. Much appreciation for all the responses so far.

Re: suspension and ignition setup need help
 

Wow. lots of feedback here. Front springs are Santhuff 250lb. rear springs are stock. Front shocks are QA1 single adj. Rears are QA! double adj. Adjustable upper arms are technically not within the rules but are not enough of an infraction that anyone complains. 6 inch rims are all that's allowed but most racers run 7s. The basic premise of the class is that the cars appear stock to the casual observer. I'm running a turbo 400 with a 2.10 first gear with all light weight internals as well as a 12 bolt with 4.56s with a spool and gun drilled axles.

Re: suspension and ignition setup need help
 

I leave off the foot brake at 2000 rpm pulling out 15 degrees of timing for 1.5 seconds.
