996 3.4 on Track Days

Length between flywheel and first crank bearing.
Crankshaft hardening process thickness
Crankshaft cradle flex.
Rod bolt deformation.

Amongst other things, basically the premise of the conversation was the M96 is a road engine and the Mezger is a track engine.

I'm sure most of these issues could be resolved with a huge re-engineering and rebuild process of this engine and I'm sure some specialists are out there who can do this, but I don't think it's a feasible solution, when the price difference between what I paid for my C4 Aero Kit and a bottom of the market Turbo is less than a total re-engineering of the M96 platform.
 
From what I can tell even the cooking variety 9A1 engine in the Carrera with it's quasi wet/dry sump lubrication system with 4 scavenging pumps is far more track suitable than the M96/M97 engines.

There was a lot of cost cutting involved in the 996/997 platforms, it's evident everywhere, it doesn't detract from the driving experience, but they're not built like they used to be, and if you want one built like they used to be you need to fork out for a GT3 it seems.

I'd sell my right testicle for a 993 at this point. :floor:

Hartech fit an additional bearing to support the crank and stop crankshaft deformation which resolves 1, 2 and 3.

The rod-bolt deformation is interesting - do you have more detail on that?

Look up the video from flat six innovations of an engine failure on track on YouTube.

I know Hartech can work wonders with the M96 but its still a 300-320 HP engine when a Turbo Mezger can be a lot more and bomb proof. I love what Hartech do and I may well be paying them a visit one day.
 
Very different cars to drive, I love the nothing-nothing-nothing-whooooooosh of a tuned turbo car, it's hysterical, although I found that I constantly chased more power when I ran one.

It's a world away from a responsive NA cars throttle response, and that's what I'm after at the moment.
 
Rod bolt failures can happen but are rare, most failures are rare, but when they do happen the internet lights up!!

I fitted forged Carrillo rods with ARP bolts, I don't expect issues.

I also have the additional crankshaft bearing, and a light weight flywheel, which also takes load off the end of the crank.

That said when my 3.4 was stripped there was no untoward wear or damage anywhere and it had been regularly tracked.

Me too I'm far more interested in a 991 GT3 RS or 993 Carrera RS than any other car, just need to rob the bank :floor:

Yeah well i'm in the 1% of unlucky sods who had a dual row IMS bearing start to fail, so I'm not really in the game of taking risks with these engines now.
