build a 3.0 into ???

[cstreit]

That certainly does sound like fun Henry. Is there even enough seating surface on the 3.0L case to fit a cylinder that wide?

NO worries on the time frame!! I have a bunch more questions!

Hmmmm, 66mm counterwieghted crank I presume.

What size ITB and Exhaust primaries would you run?

Compression- 11.5:1 or higher (race fuel only)

What sort of cam in this beast?

How would 3.2 heads work in this engine?

You have tweaked my curiosity on this one!

Cheers

Talked to Charles @ LN and he says we could put 102 in an SC case.
102 X 66mm =3236 CC.

To run 105 you need a 964 or 993 case.

What size ITB and Exhaust primaries would you run? If the goal is 8500 I would think 50 mm into a 41-42mm port & 1 5/8" primary

Compression- 11.5:1 or higher (race fuel only) I would think 11.5 would be plenty

What sort of cam in this beast? [color] DC90 [/color]

How would 3.2 heads work in this engine? sure

Supertec Super Crank
Note the lightened crank throws and hollow rod pin. This cranlk is designed to run the GT# Pankl ty rods. The are race tested at over 9000 RPM

[Jeff Alton]

Henry,

Can you shoot me an email or PM and we can discuss the $$ for the crank and rods?

Thanks

[Flieger]

The supercrank is 66mm stroke? For some reason I thought it used the GT3 stroke.

Hi Jeff
Contact me with a regular email address and I'll send you the info. Or call me
8-5 PDT T-F

BTW: The GT3 rods have gone through the roof. Porsche "gold" is always on the rise.

Stumbled across this thread... very interesting!

Any updates?

[carslutt]

wow lots of good info, did any of this planing get put into actoin?

[carrera turbo]

just listening and learning

[ONQRACIng]

I am switching from a CMW Stroke crank (77.5 STROKE from a ground 3.0 crank) with custom rods (130mm) and 100mm to a GT3 crank (76.5 stroke) and custom rods(131mm) to get back to the 3.7 I had, maybe a 3.8?.. $1800 for the crank is much better than the 4K for a CMW Billet, which due to the offset grind, can and will crackout.... Just need to figure the rod lengths..

[SCOTITUDE]

searchin for a "what to do to my motor next" and stumbled upon this thread. Whadda tease. it gives me wood. Anything get built?

[ONQRACIng]

We have our GT3 crank now, and will be ordering custom 131mm rods, either Carrillo, Cunningham, or R+R, depends on weights. Anyone else doing a similar build?

[Jeff Alton]

Our project changed directions, motor is gone, had a HP twin plug 3.0 turbo motor, but it is still on the stand and likely to be parted out...

Cheers
