New AMS Engine 23RR Engine = Big Power!
According to my calculations here are some interesting facts:
88mm 2.0L @ 9000 RPM - Tensile (tug) force on wrist pin = 3300 lbs.
AMS 23RR @9000 RPM - Tensile (tug) force on wrist pin = 3200 lbs!!
Reason for the lower tensile force despite higher G's is the lighter piston and the different rod ratio.
I'm working in the two options now and I'm thinking 9.25:1 and 10.25:1 compression as the two choices. This give the 91-93 octane and race guys a choice.

in response to this then what compression ratio should a GT37R'd guy go with on 93 + meth, and max possible boost for street/highway driving??
lol ... and where are you getting this reasonable price... when there isnt even a price out =P
ps
motor looks AWESOME!!! cant wait to hear more new from it... what are the limits of the pistons... i mean with a lighter material wouldnt that mean weaker. eh?

i'm a standard 100mm stroke 2.3 already

The runs are in 3rd gear on the dyno. Full spool on the street is 3500rpm in 3rd gear and about 3200rpm in 4th gear. Dyno it's 4000RPM
Top end is dropping off a bit because of the stock manifold and the turbo being close to maxed out.
I would recommend a 650-700whp limit for road racing and that's what we plan to run in our Time Attack car. It should be good for 750-800whp for brief strip/street duty.

What do you mean by "brief" street/strip duty??? Will the motor be a ticking time bomb for street driven applications?

How soon will you be releasing the specs?
What part of the motor would be the limiting factor as far as high hp applications?
Will the pistons be availble seperatly? Possibly in different bores?
The reason I ask, I was planning on using a K1 crank with 97mm stroke, standard length rods, and stroker pistons with the pin moved 1.5mm lower. I wanted the quick spool of a stroker, and a little more high rpm capability. Now I'm wondering if this motor, or certain parts of it might work better.
