Chris,
I noticed on the Norris site that they have only tested the 2.3 to 8300 rpm. That sounds like a standard 2.3 stroker that everyone is selling, albeit with their own crank, piston and rod selection. Do they have something similar to this AMS stroker that will rev to over 9k?
Cheers,
Robert

also another company over here, RC Developments (pants website so i wont link it), is i think running a crower stroker crank.
norris normally recomends the JUN 2.2 (with new pistons and rods i think as they managed to break a JUN rod from what i have been told!) on all but the top stuff.
thanks Chris.

Martin,
So if you were running the 10.1 compression set-up with a AMS 35R can you safely run 25 to 30 pounds of boost on a road racing track or is that asking too much.
If yes, is this something you could only do for one race season or a couple of years?
If no, what would you recommend instead?
I am just trying to get your thoughts on what is limits of pushing this motor hard, but at the same time, not having to re-build each year, when using a 35R.
Thanks- Big Boost

I'llanswer it for you.
Running that MUCH boost and that MUCH compression for a road course car is out of the realm that they would probably reccomend you running.
The "kill" setting for there car is 30lbs or close, while they normally run in the mid 20's, unless your competing against AMS there is little to no reason to run that much nor is it great for the motor.
They run there motor's there but I wouldn't personally, for a road racing car I'd like to run more compression than boost personally. I'd assume they rebuild every season or every other, the car is still new and developing so I wouldnt be surprised if it was more often than that or even if its been the same rotating assembly since the start.
I have ran MY 2.3 on the track and on the street for over 20k now, 22-30 psi on my 3076, no signs of anything wrong, and intend on doing the same with the 35R I have on it.

can't find anything on their web site either. maybe there was a hick up in some of the part orders. That would not be too cool for future use for people who needed to order replacement parts.

Coincidentally we're just wrapping this up. It's a big project and we finally got everything squared away. Testing was done and the horsepower gains and powerband are spectacular. This is a premium engine package and the price reflects many custom parts. The custom billet rods use expensive ARP 625+ custom age bolts that are much stronger than anything else available. The piston have been designed for strength and light weight, reducing stress on the wrist pin and rods. All these things add to to reduced fatigue and increased RPM range. My ideas was to create an engine that has the RPM range of a 2.0L while giving more torque and breather better at high RPM's. The Rod ratio, rod length, and bore to stroke ratio are optimized to support high volumetric efficiency. RPM range is extended by 500-600 rpm over a 2.3L stroker, making street/strip use good to 8900 RPM and road racing up to 8400 RPM.
For comparison, our 2.3L stroker made 550whp at 25psi of boost on a GT35R. After installing a 2.3RR 10:1 and changing nothing else we made 550whp at only 21psi!! There are a few choices as far as compression ratio goes and I'll discuss that here.
We're stocking two different compression ratio's and also can offer custom ratio's depending on applications.
9.25:1 Good for most street and race applications. Can be tuned to make great power on pump gas & race gas.
10.0:1 Great power and response on race gas for track or strip. Can be run on pump gas with caution and only on 93 octane (not 91).
AMS 2.3RR
Displacement: 2.27 L
Custom Billet Crank
Custom Billet rods with ARP 625+ Custom Age rod bolts
AMS Prepped 2.3RR block
O-ring deck
AMS spec Ross pistons
ARP Main & head studs
Custom Headgasket (will only work on this engine)
New Mitsubishi oil pump
New Mitsubishi water pump
AMS race balance shaft
Short block complete assembled & rotating assembly balanced
$7995.00

Any discount for a good core?
