The Swedish guy who built one had it in his 968 time attack car, with almost 1000hp, it worked after the strengthened the clamp between the transaxle shaft and gear box input shaft. I guess you will have less power than that

For you other guys, this is a mad mans project, probably nr 205 on the list of improvements you should do on your car. There's so much other stuff to sort fist if you just want to go fast but it's cool, that's for sure


I saw that post on that car and it is wicked!

Yeah, not even close especially for this '82. Just looking for reliable 200+. Maybe my GTR will be up closer to 300-400 but 1000? seriously, that is amazing. Love the vid of that car

Agreed a madmans project just to lose weight. Even though it bugs me its low hanging weight but it presents itself that way and I have to take it.

Interesting you said it was his driveshaft clamp, which I could see that being weak at that level, not anything with the tube itself.

It took some time for him to figure out the issue, it was driving the shaft forward making axial bearing on the crank wear out in no time. It got solved in the end though.

Sadly he is now leaving the 968 engine after a cracked block at the world time attack challenge in Australia last year. Now on its billet K series, but still gearbox in the rear

Was that a billet block as well or am I mixing 968 engine builds (Elmer Racing)

I get it... at some point you want reliability

No he ran a sleeved 968 block, but reinforced with bigger head bolts etc, alot of work on those engines. His spare one has been out for sale btw

They though about making a billet block, but opted out and went the K way due to the availability of fully working engine's. Keeping it together for a track car is way more challenging than flying down a dragstrip for a few seconds, they have had some challenges during the years .

I have not one chassis that could handle the 1000Hp motor sigh

Update, the alu torque tube is partially together and the small flange welded up. Almost ready...

Put the turbo on the balancing machine and took a baseline reading. It was obviously rebuilt and seemed decent balance wise. Installed the billet 2660 wheel and interestingly the balance improved. Not sure I want to mess with it further. Its crazy good. Turbo might just be going in the car this afternoon!

Also, just installed a upgraded door handle pull. I'll get a pic later. The process of installing is a PITA. Luckily the first setting was decent and the driver door opens nicely at a pull of the lever. No more yanking

Might be up the FB group already with a pic and a vid
