Well after a long time thinking i am leaning towards a differnt tranny choice other then the t-5 i was going to use. I am thinking of going with a c4 or turbo350 or there 4 speed counterpart. I am mostly bracket racing so consistancy of the auto would help also there would be less rpm drop between shifts, but my question is, where can i find a stall converter that would stall up near 10,000 rpm behind my little Peripheral port 12a?

 

Check outhttp://www.coanracing.com I had a friend that had one of their TH350 tranny's and he couldn't kill the thing. As for that high of a stall, contact them if anyone can cut open a converter and flatten the right number of veins it them.

 

I have a TH350 mated to a 13b and it's great...as for converters try Andre at Edge Racing...they do AMAZING work and are great people to work with...

I have an Art Carr 8" convertor that you could have restalled to probably 7-8,000rpm+ for a TH350 or whatever input shaft matches that spline count.

A TH350 has a deeper 1st gear than a TH400 and a powerglide is like starting in 2nd gear more for high HP cars on little tires. You could also have a Tremec TKO 5 speed manual (3.35 1st gear) proshifted which only allows upshifts and would make a great race only trans.

If your interested I have a complete C4 Setup for a 13B Mazda Rotary. The setup is in a 1985 RX7 GSL-SE. The 7" Converter cost me a fortune but, it works really good. The converter is a 6,000-6,500 stall. I like it but, I want run in a heads-up class with a G-Force or Jerico type clutchless transmission.
If your interested I will be pulling everything out of my car this weekend.

Send me a PM and I will be glad to give you all the details.

Thanks

Technically you want the converter to stall at peak torque not peak HP. I doubt you make peak torque at 10k. The C4 has the lowest internal drag of any common domestic 3 speed automatic so it will be slightly faster all else being equal. As others have said the 'glide is for cars that make huge torque and blow away big slicks with a 3 speed. I'd buy Albert's setup if I were in your shoes. If you want to get really serious you could do a transbrake and electronics like a delay box and/or 2 step rev limiter if the class allows.

 

i am thinking of getting liberty "proshift" gears for my t5 and using that, then i can still dump the clutch for high rpm launches and shift without using the clutch its quite cheap too the gears and sliders will cost me just under 500$

 

The gears might be cheaper than buying a C4 and converter, but you'll have a clutch to regularly maintain (replace) and the shock loads on the rest of the drivetrain will be much higher and can break U-joints, tear suspension mountings, etc. I'd bet that the total cost of running a C4 for 100 passes is significantly less than a manual box. It's your car though!

 

Well the car is not making much power, it will be running a built 8.8 and 4 link rear suspention, that in combo with 6.14 gears, will releave alot of stress, as for clutch wear, i think i would rather have that then overheating the tranny if i run it on the street, i would wear out clutchpacks going to most likly
