Ok, running about 350 to the wheels in my FD. Wanted to know if the kaaz LSD is enough for me to be able to launch hard. Or are shocks/springs or coilovers a must as well? Any help appreciated

 

good tires first of all . you dont have problem even with the stock torsen . try with hard suspension for rear .

 

I am running 520 rwhp and launching at 7500rpm. All I did was upgrade to a TII rear diff.

 

lerch, thanks for the input. Exactly what I needed to know. 520 rwhp launching at 7500RPM?!?!?! What a kick in the ***!

 

Thats awesome. I have KAAZ but have never pushed to its limits but it runs great. Good to hear lerch has no problems.

93 FD

 

Just a matter of time before I break an axle.

 

One more thing, I am launching with ET Streets.

 

brian henson has a 93 with a 500hp 500+tq ls1 and launches at 5500 with et streets. worked fine till he put a 100 shot on top of the 500tq he had. the kaaz worked great but the axels didnt. so yeah if the kaaz unit can hold some off the line V8 torque it should be fine

 

Hey lerch if you break an axle what axles are you planning to replace them with??
Also What suspension set-up do you have??

 

axel
RP Chromoly 300M Axles are a good up grade

 

Yea, he ran the stock diff/axles for a long time, then he started launching around 6K rpms. The stock stuff doesnt break from the tq, it breaks from the high rpms that single turbo guys have to launch with. The Kaaz and the clutch style TII diff both can hold up to high rpms launching just fine. That stock diff just doesnt like to see 6000 rpms from a dead stop haha

"The stock stuff doesnt break from the tq, it breaks from the high rpms that single turbo guys have to launch with. "

your post makes it sound like you know brian but the statement dont fit he aint got a single turbo hes one of us LS1 guys .

 

the only weaklink that is hard to fix in a FD is the tranny. i had a T2 diff, upgraded PPF, 300m axles and all i broke was 3 trannies ! i was launching at 8500rpm off the rev limiter though

 

can you tell me why you launch so hard vosko. I would think 5 or 6 k rpm should more then get them wheels spinning, no?
