Broken 3rd gear x 3

Stronger gears would be in order for a high RPM application, no?
 
I don't know what kind of senior engineer I consider myself by asking this question but what would be my axle ratio?? Are we the same as listed by Fulcrum 4.11?
 
i am lookin for on of these for a long time.
Par engineering, you make something for about 700HP ?

700hp ATW will require a dog engagement gear set if used for drag racing. The synchromesh engagement will be ok for street use if your gear changing style is very smooth. ie. clutch out before power is introduced. Flat/Speed shifting can push some serious shock load through the gears resulting in a much shortened lifespan.

I still want to be able to cruise with the car once in a while.
i want the car to go home runnin. not on a trailer.
so Synchromesh.
 
KL + NOS + GT37R

do you have a web-site or a thread where we can see your build ? your current setup sounds impressive, is these for a track drag racing, or is your daily driven one ? street use ? what kind of car we are talking about here ?

My gearset is here! Man was that fast but I also had to have PAR order the Double synchro assemblies from Japan so that will be a few more days. Still have a few more things to get ordered that may have to wait until pay day!

I'll pick up my camera at lunch and post pics. I'm getting too anxious!!!!
 
REALLY? What else... cuz that dont appear to be 700 ponies to me. BOV, piping size, shared intake runners... too many things say about half that. How bout a dyno video??

The most I've ever seen from a KL is about 500HP. There was a Dyno sheet on that one. There have also been a couple in the 400+ area, but not many.

Never heard of anyone over 600 before. Unless you count that Australian Race car with the twin turbo's, complete rebuild and custom IM, It was over 800HP. It's now in another car with over 1000HP.
