Thread: Transmission strenght

Wow, you've got some serious horsepower there. 8)

What will break first? Well my opinion is a toss up between the front axles (halfshafts) and CV's, or the LT77. If you're into rockhopping and bouce the front with that sort of hp, then CVs and halfshafts will become consumables, at least until you maxidrive/mcnamara/longfield it. If you can take care of the front end, then the LT77 is the next weakest link.

I wouldn't anticipate trouble with the LT230.

All just my opinion of course. [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Anyone else have something to add here?

Sounds about right. I'd pick the cheapest part to replace and make that my weakest link because somethings gotta give.

The car is not used for rock crawling (or much else for that matter!) if it saw low range for 10 minutes a year it would be a lot.

The engine set-up we are working on is reputedly able to produce 800hp if we turn the boost up to 18-19lb.

Now 800 would see the whole driveline drop dead.

Of interest what transmission/driveline would you run to handle 500hp? As the car is going to be supercharged it will have enormous torque.

I would think a Tremec hooked up to LT230 running thru some exotic diffs. Lots of engineering but could be worth it.

Tremecs are strong. But remember it's torque that breaks stuff. A mate of mine runs a Tremec behind a blown 393 chev fitted to Jag E type, car is used hard for hillclimbs, historic street sprint etc. You could consider a GQ patrol box and transfer case.

What about gearbox mounts ?

They worth thinking about as well ?

swap in jag v12 engine mounts same hight as rover but larger.

Keep the LT230.

NV 4500 best optio n if you want manual.

Auto run the ZF with the V12 jag clutches in it.

swap in toy diff centres into rover axle housing run Jac Mac axles.

CV's longfiled Chromo .

best set up around.

Thanks for the comments. Greatly appreciated.

ShaunP,

I agree torque will do all the damage. An Auto would make more sense but I like driving it as a manual.

Hellspawn,

The car had tandem mounts all around as part of it's original build for the Safari. The rears are staying as built but the fronts needed total replacement.

HSVRangie,

I am usung custom mounts to squeeze the Lexus engine in. I am currently looking at the double mounts and trying to integrate the old tandem mount system

Now I will show my ignorance!

What is an NV4500 and what is it out of.

I understand the LT230 is pretty bulletproof.

I never realisd the ZF would carry the sort of power we are looking at.

You lost me on the diff centres. I think there may be a typo in there.

The CV's make sense.

Swap in Toyota Diff Centres.

Both HSV Rangie and Landy_Man have this set up, very strong.
