What happens when you have too much power, and a weak transmission? :)
Its a 383 stroker, nitrous, and it uses a 98 Cavi Isuzu 5spd tranny (thats holding up sofar) i dont know what the other one was...
Her car is notorious for going thru trannies... someone said that 383 stood for "3 years, 8 transmissions and 3 clutches" :D

And a questions for ya'lls..
Does cryotreatment, and stress relieveing actually increase the parts strength? Are there any numbers someone could point me to?

Cryo treating is a process where the metal to be hardened is frozen using liquid nitrogen, then slowly heated up to about 350 degrees farenheit. The metal is cycled like this about 3 times over roughly 72 hours. Basically it is just an extension of heat treating, and usually provides about 100 % increase in fatigue strength, and wear, with some improvements in tensile strength as well. It works best on ferrous metals, like steel, that have already been heat treated. Good to use on highly stressed parts, with no negative side effects.
Shotpeening is a process where millions of tiny steel balls are shot at the part at high velocities. This causes the metal to be compressed, and refines the grain structure on the surface. Basically it is micro forging the metal into a harder layer, which makes it harder for a crack to start. It changes the structure of the metal about 0.005-0.010 of a inch deep. Typical improvements in the fatigue strength are in the 100-300% range. Very good at preventing breakage, typically used on airplanes.
Hope this helps |

| is this the unicorn car? |

Nah.. the unicorn car uses a Hydramatic 4T60E or a TH125 i believe..
This is a Isuzu 5spd, a variant of what currently comes in most manual GM cars.. the 98 Isuzu tranny pictured (the one thats not damaged) are a bit stronger than the older ones (the one that is destroyed). It sofar has stood up to a few race days...
