Funny you say that! Our 993 Twin was pictured/small featured in Hot Rod Magazine for fastest street machines!

Oh yea, I wasn't implying anything devious, just the point that it takes a lot of stress to twist mainshafts. The G50/52s have a stronger mainshaft...

TRICKS" JUST GIVE US SOME PROOF OF ACTUAL PERFORMANCE (WE PREFER 60-130MPH), AND
TELL US ABOUT THE CAR, IE. CAN IT GO AROUND CORNERS AS WELL AS RUN THE QUARTER
MILE, ETC. WE LIKE STRAIGHT LINE ACCERERATION BUT WE LOVE!!!! PERFORMANCE (CORNERING
BRAKING, ABILITY TO NEGOTIATE A TRACK WITHOUT HAVING TO CHANGE ANYTHING BUT A FEW
TWISTS ON THE SUSPENSION AND MAYBE TIRES... GIVE US SOMETHING TO GO ON

Not that I mind the attention, but first and foremost, I didn't enter this thread claiming to have the best 993 Twin in the world, I commented on a post of "550 whp unatainable" on a stock motor. For the record, this was done with 2 to4e's with stage 5 wheels and a custom intercooler.

I think the misunderstanding arose from the fact that most of us meant reliable, without lifting heads, and likely to last more than a few weeks. E.G. not a hand grenade

I don't remember how long the car was making 580, I wanna say 6 months, but i'm not totally sure. Same turbo's to4e's.
We've actually got a customer car that makes almost 500 whp through stock mufflers! And a handfull of 993's that make in the ballpark of 515-530 rwhp, stock motors. We've done a few 996 twins that make comparable numbers as well with boltons, but that's a whole different scenario.
I say rwhp because we don't chance blowing out the viscus(how do u spell that?) on a awd dyno so we disconect the fwd for the dyno runs.

To clarify further, what I said in my previous post is that with a stock 3.6 engine (read non modified heads) at 1.2 Bar and a mass air flow system you CANNOT be reaching appox. 750 Flywheel hp (620 rwhp as claimed by you), or anywhere close to it. Also stock injectors, stock single fuel pump? I don't think so. You would need to crank up boost to at least 1.5 Bar to get that output, if you ever get there since your T04 turbos will be overheating at those levels unless you have a heck of an I/C among others (most likely you used a Spearco core 2-176, the largest you can fit in there?). What kind of charge temps do you see at those levels?
Concerning blowing off the heads, agreed that a setup like this (that takes you to 620 RWHP and NOT 1.2 Bar) will not take you very far.
Please keep more information coming Jim, you haven't disclosed any secrets yet, these are all BTDT stuff.

Probably headers as well. This setup will in anyway give you a very important lag, up to 4000 RPMs you would be around 400 ft/lbs of torque at a max, which is considerably lower to what TB993TT's car is doing for instance, I don't see you accelerating faster from zero with such a torque curve.

This is what I get for disclosing which turbos we were using *sigh*
No Jean, do not assume that we used an aftermarket header. Aftermarket exhaust(obviously), high flow cats. Who said stock injectors, who said stock fuel pump, who said stock anything besides the heads and motor?
You're leaving out major gaps in your "theory" of how flat 6's make good usuable power.
