What cubic inches for d1sc
You could feed a 39x ci ls1 or a 402 ls2 with a D1, My vote would be the 402/ls2. There are a few guys on here in the 9's with bigger ci and a D1.

anything from 346 to under 400ci search Trust's threads he made over 800rwhp with 396ci Auto 12bolt car
with 400+ci you can get over 700rwhp with less boost though...

I have a 416" LS3 using a D1sc with single intercooler. I am getting 15.5 lbs using a 3.75" pulley and a 7.25" balancer. This is 53000 rpm @ 6600 engine rpm, blower max rating is 62000 rpm. 858 rwhp 780rwtq
Damn, that is not bad at all. I wonder how that would hold up on a 427" LS3/LQ9 (4.07" bore 4.100" stroke)?

So if I ever want to strap a blower to my iron 427 and put 15psi to it I should probably only consider an F1C or F1A.

You see forged 347's, and forged 370's, and some forged 383's but never forged LS2 -364's with stock crank or forged LS3 376's with stock crank with D1.
Most seem inclined to want to go to 402 or 408 with a D1 instead of just forged pistons leaving the crank stock.
Why not a forged 364 or 376?

That was my exact thought i would think a non stroker motor would rev faster but i could be wrong. What is the benifit of a stroker motor with boost?

Check out the above T/A. We managed to get 16 psi out of the D-1SC on the 402, but it was overworking the blower.

Check out my Camaro in the above link. We managed to get 19 psi out of the F-1A with my 408, it was maxed out as well.

Check out the above '08 Z06, where we built a Warhawk 427 and installed an F-1C, then we swapped the F-1C out for an F-1R. We then got 19 psi out of it. This engine had heads and an intake that flowed too well, this engine needed an F2 blower.
To answer your question, on a 427 I'd go with an F-1C or an F-1R. Bob

These motors make so some much power and torque anyway at 10- 15 lbs of boost that I never did agree with the argument that you need a 402 or 408 for the street because of more torque. The LS3 is torquey enough for me and car will be all street - no drag.
My current setup is HC stock bottom end 347 with 8rib D1SC with a 4.38 pulley. On a very safe tune makes 565 rwhp on a Mustang Dnyo. So a forged pistons only LS3 376 should do me just fine as it won't be a drag car (1998 Z28).

Check out ChevyChad's recent thread about adding another pulley to a machined standoff w/standard j-bracket. That along with the 8-rib set-up should make it difficult to get belt slip.

How about a kit we can buy and bolt on for us that don't have access to CNC machinists?
I like the idea of a machined standoff bolt and pulley and longer belt much better than the SDCE setup selling for over $700.
