trans work necessary for 450hp

Quoting slugsgomoo:
well 4th gear is weak, and without a trans cooler, I would definitely forecast bad things there. The truth is, 1st gear, center diff, and 4th are probably the three worst things in the stock gearbox... avoid them /ubbthreads/images/graemlins/laugh.gif



3rd gear rolls are what I avoid. 4th gear pull is just asking for it. Look at how small any gear on the trans is, then ask it to hold 400+ ft/lbs of torque, with absolute traction, and heavy load. They don't last. You have to change your driving style and what you do and don't do if you want your gearset to last at higher power.

OP, don't you have to make 450hp first? /ubbthreads/images/graemlins/dunno.gif

If he has a 16G it's easy. Well after some very thought out calculations, ain't that right G?

Hell naw it ain't easy, maybe in canadalandia /ubbthreads/images/graemlins/rofl.gif

My car makes 450whp. My TMZ/Southbend clutch and ER built trans seem to hold it all just fine.

DSM 1st, double cone 2nd, Evo3 double cone 3rd-4th, welded center diff, heavy duty shift rails, etc. Neo RHD fluid.

My FP 68hta and e85 tuning should get me pretty close... but if the trans can't handle it what would have been the point?

G should stick to his rust and peeps discussions.....

Is there a way of attaching a trans cooler?



You'll need to weld on some fittings for the drain & return, get a cooler, filter, pump, etc. The good news is, it's been done before, and it's just fab work. I think that people have decided that returning the fluid over the top of 4th seems to be the best bet.

So it's been over a month and I have gotten my diff back... they said it would take a week. Anyway.

Do I have to add atv when I measure the shim gap with solder? Also what's the torque spec? I need to find my manual..

You have to change your driving style and what you do and don't do if you want your gearset to last at higher power.


Elaborate please.

OK... another bearing shim question. It seems that the center diff isn't sitting straight in the case. I'm consistently getting measurements of 1.56mm and 1.67 or around there each time I check it. Point is side to side they are different each time. Now what. I have three shims I'm about to throw the smallest.14 and the biggest 1.5 in and call it a day.

Edit:
This seems wrong now... I used 3 smaller prices of solder and got an average of 1.45mm. So now it looks like I'm out of spec by .12mm. Wish I left out the second shim.

How much of a problem is this going to be? I don't want to take it apart again.

Driving style, clutch setup and fluid are also very important for power handling.



This.
