sharkster,

You didn't believe me .......... did you? And I bent all six. I wonder who is going to be the first to have a rod let go?

Nah I saw the pix... I knew you did but I figured it had something to do with those 7krpm drops with NOS Mine weren't as severe. All I could see were two of them (at least visably).....

In terms of who will let a rod go first, I'm not sure and I hope nobody will/has... I'm guessing with more and more turbos putting on mileage (since most people do drive them that own them) with these high HP packadges, we'll probably see more people tear them down every 40k or so...

No, we have done it for years. It will hold the case together. The issue is the two halves moving around. Not a good thing to have happen to the mains. The 2.7 case was a prime example of why we do this. Look at Porsche from the past. BIG HP is nothing new. 962, 935, 956 and so on.
Ah-k... Big HP has been around for years. I saw some video of a yellow 930 once lol....

I'd love to see what you'll be doing to that TIP Sharky. Waiting for an update with pics, if possible.
On the other hand, I do agree that the less lag you have the better the car would be on the track.

So...what do you guys consider HIGH HP? 700 and over? 600 and over?

Im just wondering if I need to do this as well. Grant it I havent been at 600 for 30K miles (maybe 11K), but what's the overall consensus on when rods should be replaced, etc. for us lowly 600HP guys? Stephen?

Well ETA is 3 weeks and then I'll need to break it in again... But after that I'm gonna go back to the track and make another low boost run with the new stuff. After that Todd/Mike are going to take the car back home with them to get high boost sorted

I'll post some pics soon... When I say that I only bent two, I meant "visibly". My guess is that if you put 'em on some granite they're probably all bent. It's just two are worse than any of the others....

I'm going with Carillos

Alex, it's nice to see that you are replacing the rods, finally!!! I think that you should think about shuffle pinning you case.. The case is walking around at #7 main web.. I have written a CNC program to handle it on my CNC...

Bill, 650 flywheel is the limit.. beraing wear is taking place..
Well you did tell me over a year ago that'd I'd have to do it- finally now was the right time That's some good info. Was it doing that also with the 993TT?

There's some stuff I'm having done to the crank (although I don't think I'll be knfie-edging as I'm worried about weaking it). I don't think I'm going to flow the heads though. I might do some additional motor work as well but I'm not planning to do super high revs or anything like that....

Most of them showed some wear and obviously a couple were worse than others....
