My car is a 71 Dart Swinger, weighs 3120 with me aboard.
Trans was a Pro shifted/ Face plates 833 Hemi 4 sp.
Motor 416 LA /w Magnum heads. 13.5-1 , .670 solid roller, M-1 and a 950 Ultra HP.
The first clutch was not even close to what i need, got the "recomended" parts from the Tech line, .
Here's what it looked like after 10 runs....
I had no idea the engine shop, Mid Island Engine...in Duncan Bc, threw the motor together, did NO math and gave me a 15.2-1 engine the barely ran on C-12.....Needless to say it detonated BIG time , blew the head gaskets, pistons hit the heads, and had cap walk so bad the caps looked like a fat chicks legs...sickening.
THe car ran 10.513 twice, the same weekend as sick as it was.
I rebuild the motor and put a paddle style disc in, used the same pp.
I still used the same trans...I did rebuid it and face plated 3-4...1-2 were alreadr Pro-shifted
The best times were 10.30 @131. The car ran in the 30's 3 times.
I am definatly happy with the results, but the set up have now only slips at 4000 rpm.....i need more launch rpm
I have an Adj set up from Adv clutches I have installed and a Lenco with a deeper 1st (3.04).
I am also changing the shocks to double adj to control the rebound and help get the car up on the tire.
There is alot more to running a "stick", than most people realize.
I had to replace soo much because I made my initial decisions based on the dyno results of a sick motor...it made 520 hp detonating @ 26* timing....now that it's fixed we figure it makes closer to 600, based on the speed.
An adj set up was highly recommended to me from the fellow i bought my first trans from....
I guess the big questionis...."How many times do you want to spend your $$$ fixing breakage THAT CAN be prevented"?????.
I didn't race at all last year due to my trans upgrade and I was out of work for a couple months.
If you want an industructale trans look into the ST1200. When you compare them to the other choices...I think they are a better deal....
No more missed shifts, No maintenace, they come with shifters and the output yoke.
I'm not a rich man, I just want a tough breakage free ride. My tires are going to take a beating...but I hope to eliminate my driveline issues, and I think I have.
I have a friend in town who runs a G-force 5 sp and an Adj set up on the street, all he does is adj the base pressure to drive on the street.
1 thing that is a great aid in tuning and seeing what is going on is a data logger..but that's a whole different kettle of fish...
Steve....pm me if you want, I may be able to help you or know people that can.
