Well 12,000 and 5,000 sounds pretty good, nice round numbers, you know? From some of my conversations at ET, what I understood is that they want to be very methodical in their approach and try to achieve power/torque goals in a logical manner rather than just throwing caution to the wind. I believe the next numerical goal is probably in the neighbor hood of 950 to 1000hp. I know they stretched their dyno window as far as they could and still get this thig ready for the PRI Show next week. I believe that 9500 rpm's is the ultimate target goal and 1200 hp. Pretty cool stuff... 
As for our plans at World, have the tall deck block to research. We know we will go to at least a 4.25" stroke, quite possibly a good bit larger. We just want to very careful about what we advertise, especially before we do in depth testing.

9500rpm and 4.185 x 4.125? Am I reading this correctly?

I want to test a tall deck at Katech.

Jason,
Sorry, I was unclear. The project is a 9.24" deck Warhawk block, 4.185" bore with a 4.0"stroke. The ultimate goals are looking for a max RPM of around 9500, with a max hp reading of around 1200. At this point they ran out of time because of the timing of the PRI Show. After the show it'll be back on the dyno for more tweaking!
As far as you testing a tall deck at Katech, I'm sure we can put that in the works!
We'll work it out!

Welp.... Looks like I've been assured of what I'm building next fall. Big cubes, and a big *** single turbo LOL.
I've got some serious goose bumps over the sweet song that bitch must sing at 7500 RPM. 9500?

Jason,
"We warmed it up and broke it in last night. We had a chance to make a few sweeps, the highest being 7500 RPM. we still have 2000 rpm to go." - From Cary's post on LS 1-6.
This is a 4" stroke build, 440.1 CI. The speculation on 4.125 started on posts #13 & 14 here.
You're right-this is how it begins.

At 9500 rpm the piston speeds are WAY beyond what we are comfortable running. 4.185 pistons have got to be over 400g. I just don't understand how it is going to stay in one piece.
Don't shoot me. I'm the messenger. The thread I posted has the details straight from ET's mouth on "ultimate goals."
I honestly don't see the point. I've seen 2JZ-GTE Supra engines run 9+k with an inline-6 and that's VERY IMPRESSIVE. But necessary with those absolutely massive turbos that don't peak until 8500+.

2JZ 3.385 stroke @ 9500rpm = 5300fpm piston speed
LSx 4.125 stroke @ 9500rpm = 6531fpm piston speed

Thats how bikes rev to 12,000rpm or F1 to 20,000 (among other factors in F1).

Also, 40-42psi is being forced on top of the 2JZ usually and some of the newer "super builds" are using stroker cranks and overbores for 3.4L and still spinning to 9500 with over 40lbs of boost. It's impressive, nonetheless.

Katech its a 4" stroke not a 4.125 (remember what you were saying about things being mistaken and this is how they start).
What type of pistons are being used (hopefully light weight alloy forgings).

Our goal at this point is to highlight what ET is doing and show that it is impressive... Our goal for our block is to show that it is a piece which has great quality, durability and hopefully affordability compared to some of the other available platforms out there... While our goal is certainly not to disprove whatever concept ET has in mind for their package, it is not as if we are a driving force in the direction of their project. This thread should be viewed and used to communicate on those issues/ideas. ET has their own thread about this project and that is where it would be appropriate to discuss the viability of the direction of the build and project goals. We hope that ET is able to reach what ever goals they have set forth with regard to the build.

I was not mistaking anything. I was talking about the suggested 4.125" stroke version.
