OK So my T56 DR experiment first time out
#61
Thanks for all the great responses. Although weather and Import Wars kept me from the track yesterday I talked to Madman and he says we will get it figured out. Just need to get to the track take some good vid and see what it looks like then he will steer me in what to do. In the mean time Ill get the car up on 4 ramps and recheck the PA and take a look at the yoke.
Again It does not feel like the clutch is slipping nor can I notice it on the tach but something is def not right. 124mph is way low for a 200shot. Its gone 119+ on motor. Im 100% sure the limiter is set at 7k. Its been the same for years and matches my tach perfect. Also sure it has 4.10s and 28" tires.
Rob Ill do everything I can to be at RSD. Wont be doing any money races until this POS is working right but at least we can T&T and thanks for the help.

it takes time, wont happen in a day nor reading LS1tech all day long and changing **** based on what people post....you need to log every run and every thing about the run. change 1 thing at a time, not multiple things.
know what the DA is. What the 60' and 330'.
it all about spending time in the seat....which is hard to come by @ times, I KNOW!

Does anybody think its a possibility that the UMI drag bar could be set wrong? Causing the issue? Thats the one other thing I changed but forgot about till just now.

I had a twisted slip yoke this year also. I was cutting 1.6-1.7's last year with slp lowered suspension. 1st few times out this year I always blew the tires off instantly and was cutting 1.85-1.9 60'. Checked my slip yoke and sure **** it wouldn't slide all the way into the tranny and was twisted. Replaced it with a strange chromemoly yoke and 1st pass out I was back in the 1.6x's. It played hell with me so I highly recommend checking that on a stick car.

With the pst shaft, twisted splines are a definite possibility. There stock yokes are crap. Even the strange cromoly yoke isnt that great. If you have a bad yoke I would switch to a mark williams. He uses a heat treated forging that he then machines down, and it is awesome. Only a little more that the strange unit and is the same piece they use on pro-mod cars. I can't see the drag bar being the problem.
Watching the videos on slicks, the car did pretty much the same thing only more violent on the hit because of the old shocks. It bounced the tire off the ground causing the spin, then hooked and bogged. The shocks and drag bar should have helped that alot, but maybe not so much on drag radials.
Definitely keep us posted. I gotta know whats up with the gear/tire issue. Everyday I'm waiting to see if you figured that out.

I know its driving me nuts. Tonight Ill have some time to get the car on ramps and start checking things. I also wonder if I raised the front of the car a bit if it would help with the weight transfer issue, or maybe tighten the extension on the front shocks to slow it from rising to fast.
I also picked up a th400 that worked fine when pulled. Now i need to decide if I should use my built th350 or have the 400 built for when I do swap the trans. BTW the 400 was free.

Your gearing sounds off because I just upgraded to 28" 275/60/15 from a 26"et streets. I have 456's,and was just bouncing the stock rev limiter at about the same 1200' mark in 4th with 26" tires mph was 110

Thanks guys I should be at RSD unless it rains and I will use the 350 when I go A3. Ended up having to work on a buddies motor so no update if I found anything on mine.
The gearing does sound off but Its the same 4.10 gear thats been in it. The car used to go 1.6 60s, 11.6@119+ NA and would pull through the traps at just about the limiter in 4th on 26s and QTP 27s. Changed to 28s and new shocks and bam this is going on.
You guys think the bog is so bad 1st is being useless and making it so im practically starting in second?
Also If the PA is way off a new TA will be ordered asap.

Alright I got the car up on 4 ramps and got some measures.This is what I got with the angle finder. I also found the TA tore threw the front bushing and was stopped by the bracket, so Im not sure how accurate these are. I heard that doesnt affect PA just IC??
If I moved the bracket to the top hole the TA would be in the spot it is now.
rear TA bracket
drive shaft
I also did the floor and that was -2 on the finder
and the LCAs were +2 1/2
I measured the front fenders with the car on the ground and from the fender lip to the ground it was 26 1/8" on both sides and with the front lifted until the tires just barely touched the ground was 30 1/4" on both sides.
What do you guys come up with?

I already have a UMI TA relocation trans cross member on the car. TA was set in the 2nd from the top hole.
