ISF with IS350 Diff...
Il be at the track on Saturday with MS109, 150 shot, the new nitrous controller & obviously the diff. I think im going to shift around 6,5oo rpm because with the 4.09 the transmission only drops 900-1500 rpm when you shift and that will keep me in the peak of the power. Should make between 550-575 hp and 575-600tq at the wheels once the juice kicks in. I have it set to spray in 3rd and up at WOT between 3000-6400 rpm... il probably run my slicks around 11 psi. Wish me luck 




Go get 'em!

i broke my axle loose prior to lowering the diff. I use a big flat head and stuck it in between the axle and the diff and pry it out until i feel the lock ring pop. from there i lower it half way down then pull it out..
Thanks!

Axles are out, driveshaft is disconnected and I dropped the axleback out of the way, but there doesn't seem to be any way to get the diff out.
What else am I supposed to disconnect? Everything is moving, but there isn't clearance enough to get the axle out of the diff, no matter which way I move it.

DOH!
I guess I should have looked closer at that. That did the trick. For anyone else who isn't the sharpest at turning wrenches (like me) if you pull off the two plastic triangle pieces (they are held on with two small nuts on each side), you'll see the cross braces.
One axle is out. the other snapped back in when I was fighting with it. I'll have to bolt the thing back up tomorrow, pop the other axle out and finish the swap.
I did my F-Sport sway while I was under there. Of course, that had to fight me as well.
I ended up having to pull the end links out completely and clean up the threads before I could get the nuts off. Hopefully, everything will be done tomorrow.
Thanks, again, Obby.

Just got back from the track... Only got one run in before it started raining.... 11.6 at 127mph god dam I hate rain... I will be back soon to try again with those trap speeds 10s should not come hard
Nice run. 127mph is decent for your power range. How was your 60'?

It had ben raining all day on and off so the rubber on the track sucked.. I ran a 2.01 60ft. I was hitting the speed limiter just before I crossed the line. I think the 4.09 diff is a toss up on high power ifs because it rips threw gears so fast is barely has time to put some power down and I think I hurt my 60 ft cause I was spinning more with the new gearing. I will prob put my stock diff back in the car or try a 3.7 from a gs
