Here are some graphs of runs done before and after our stroker motor upgrade.

Runs are at base boost 13.5psi , that's the lowest it will go. 93 octane and AEM EMS. We wound up making a 430whp and almost 400ft-lbs of torque at 20psi on 93 octane with a conservative tune, meaning you can beat on this thing all day long.

BTW we have some new trick stroker pistons we just came out with. They are designed to take advantage of the quench area on the head and provide squish. = more efficient combustion, more power, less end-gas, less prone to detonation. We just got them in today and it's what we'll be running in our shop EVO VIII.

Very nice. Can't wait for full boost numbers. What is the highest this kit can spin safely?

 

As you can see it makes about 15% more torque than than a 2.0L and it makes 5%-10% more power. I've been spinning it to 8K and I would recommend a max of 8.5K for road use and the occasional road racing and 9K for only brief periods (such as drag racing). Tim spun his 2.3L last year to over 9K all race season last year with no problem. We will be offering cryo-treating and shot-peening as an option, which will increaes the RPM limit.

So it gained about 40whp switching from the 2.0 to the 2.3? How much is the stroker kit for, and how much would it be to install. PM me with details please...

Tim

 

AMS as always the best !

 

What is the RPM of the redline in the 2.3?

 

Bump...

 

some quick questions about the 2.3 build that you guys are offering.

block exchange-so different id # on the exchanged block, and will this cause the title to say rebuilt or salvaged?

- how long to build my block into a 2.3 with the price offered on your website?

Thanks in advance and please pardon me if these are newb questions and have been answered already. Please PM me with answers if more appropriate

 

start the dyno pulls at the same RPM next time.....might be a better indication of power. IMO

 

Starting RPM will not affect horsepower unless you load the engine so long it heat soaks. For example starting at 1K rpm in 5th gear with no fan on the intercooler, then doing the same run starting at 4K rpm. Starting RPM can make a difference on spool up. If you do the run within a few hundred RPM of each other, as this is the case, then the affect will be negligable, trust me.
We just ran the car at 24psi with water injection and made 501whp and 430ft-lbs of torque. I did some road tuning with this car the last few days and it will start making boost at 2200-2400rpm with 10psi by 3K in 4th gear and 24-25psi by 3500-3600rpm. Awesome car to drive with a very wide powerband, perfect for the street or road course. You have full power and torque from 3500rpm to 8000rpm. Where the stock turbo start to drop power at 6500rpm this thing keeps making power all the way to redline. To compare power bands, the stock turbo hits full boost at around 2.9-3K rpm and makes usable power to 7K rpm, the stroker 35R setup hits full boost at 3.5-3.6K rpm and makes useable power to over 8Krpm. Not only are you making much more power but you are also extending your usable power band, which is very important to having a fast car. Peak HP gives you bragging rights, wide power bands give you a fast street car. If you have high HP and a wide power band then you have the ultimate street/strip car.

What is the cost of the kit? any installation pricing too?

thanks

 

Man is 500whp and 430ft-lbs a limit for WI and GT35 on 24psi?Or it was`t tuned right?
And with which mods?
Because DunoFlash has got about 600+whp and 600+ft-lbs but on straight methanol...
Thanks

 

Also bumping on installation cost. Or is that intro rate 1995 for the kit installed.

 

sweet, is that witht he ported head as well?

 

Your comparing apples to oranges here my friend.
