Knackered 3.4

With reference to wear on my engine,bottom end was definately gone,but I did hear it starting to tingle,I know from race experience to stop immediatley but did'nt.That would have saved the crank & rod. Grant said the pistons were savagable.I just went the 3.7 route because you can't have enough torque or power.I am not gentle with any car I have and have a scrap box with destroyed engines from Alfa 16v flat 4's,inline factory race 2 litre twin cam. Cosworth turbo with cracked blocks.Rods through the side in Cooper S. All engines do go bang if you take to the limit. I did have the 996 round Millbrook one day for exercise.The bill for the engine is compareable with the engine I am having built for my Cosworth.I have been told not to take the 996 on track when done and enjoy it as a road car.Will update with progress.Mike.

:eek: this may explain a lot..
 
Maybe a custom hard cut limiter next time?
 
Yes, that too, I was more thinking of the box of miscellaneous broken engines having a common theme

I would hope the 3.7 redesign addresses the oil starvation in long high g corners, I think I read hartech do something to counter that design flaw?
 
I have to say in my defence that most of my blown engines have been during races. The 996 was I am pretty sure oil surge. I haven't tracked it,just did one day at Millbrook wit CAT training.Mike.
 
You can dry sump them,just replace the bottom end with an early 991/964 bottom end.
 
Hah, simple.

I didn't realise that the 964/993/Mezger was staggered in the opposite direction to the M96/97. Underlines how different they are.
 
Hi,picked the engine up today from Hartech. Had a full rebuild,3.7upgrade,race sump so hopefully no oil surge.Will start putting the engine in tomorrow. I have new AOS,new manifolds + Topgear exhaust amongst other parts. Hopefully have it done for christmas to play with. Mike.
 
Happy Christmas, what a great project to do when you have a few days off work. Enjoy.

Nice choice choosing to upgrade to 3.7! What was the original fault in the end?
 
Hi,it had run a big end,buggered the rod & crank. We decided to let Hartech have the pleasure of rebuilding it. Steve is used to Cossie turbos & M3's.He will refit the engine etc & get it running. Will let you know how it goes. Mike.
