Mark,

Can u give a description of your stroker kits, power output, and also what kind of associated equipment recommendations?

Thanks,
Wilson

 

http://www.slowboyracing.com/shop.php?sid=&cat=1245 there are the different kits. Power output is limited to the rod strength, and wht turbo you have max poweroutput. Keep in mind a 2.3 wont make more top end power really, but will increase torque and and power response..

we also sell these assembled in the blocks already with the required clearnacing of the block needed already done, with and without cores.

Thanks

could you pm me on how much it would be if i send you my core?

 

Stroker is definitely a good idea Wilson!

 

Yes do you have to have aem ems or similar engine management to run a stroker setup. Is at all possible to use a piggyback computer like utec?? I want to go bigger and like the idea of faster spoolup, but I don't want to go HUGE if that makes sense. I would like this setup but with a more conservative tune and more streetable. I guess I want more power with as close as I can get to stock like drive. thanks allen

 

No you dont... Its no different than running you stock engine in that aspect. You just see a better torgue response and low end power. With the stock turbo you wont even feel the turbo spool, it will feel like a constant power with no lag. With the 2.3 motor you can use a larger turbo(within reason) and still have stock feel for spool up b/c the displacement will increase spool time on the larger turbo.

just curious, what is your definition of "spool-up"? because those graphs, dispite how amazing they are, show your not reaching max torque until just under 6000rpm. that to me says your not spooled up until 3000 rpm after stock... generally spool-up means you reach max boost, where the car is making the most power.


but mad props to the big numbers!

 

to do a stroker motor does any machining have to be done to the block, or is it just the Crank and pistons that make the difference???

 

This is amazing, awesome work guys. Thanks for the quick answers.

 

Your car doesn't make max power at the exact instant that you hit peak boost. If that were true supercharged guys would make max power at 1000 rpm.

 

well we were reaching full boost (22 psi) on 94 oct by 3k on the GT35R. Now i know EVO guys do not like turbo lag, and 3k full boost is hardly lag.. LOL.. Now yes your tq peak isnt at that point, but when is your peak tq/power ever at the point you reach full boost on any car?? I know my MR doesnt reach full boost until high 2k RPMS.. so i will take the couple hundred rpm difference for the power gain of thel arger turbo on a 2.3 engine..
Thanks for the props!

other than dropping in the crank and stroker pistons with an upgraded rod. you need to clearance the block (bottom of the cylinder walls) so during the longer stroke, it doesnt hit. The amount needed to be removed is about 1/8-1/4 inch depending on what rod you choose..

Thanks, thats what we are here for!

Exactly... thank you!

Sweet engine!!!

 

supercharged vehicles generally do have extremely flat torque curves. thats because they don't have turbo lag obviously...

here is an 03 cobra with nothing but exhaust. you can see the instant they started the dyno run he was at max torque +-25ftlb. this is by no means the best dyno i have seen, but i did a quick search to find it for you. notice that there is no huge rise in torque as the supercharger builds up boost, primarily because he doesn't have to wait for the boost.

in the GT35R stroker plot with 500+hp, hes not making peak torque or HP until 5-6k rpm. and if your making max boost at 3k rpm, there is something severly wrong with your car or the dyno. the HP curves are always rising because it is a function of RPM and torque. the torque curve is rising because you are still building boost and increasing the torque... although the power is insane, i would want to see a plot of your boost level on that same plot to believe you make peak boost by 3k rpm. i would bet your not making peak boost until 5000 rpm which is no where near stock (but then again your making more then 2x as much power as stock which i'm sure is fun as hell regardless of the turbo lag)

so just to make this clear before it starts a flame war, i am impressed with these numbers. i am not knocking on any products, i am just trying to clarify that either this car is indeed making max boost at 3000-3500 rpm, or if the larger turbo even with the stroker setup, is just to large to make "useable" power (and by useable i mean having a power band greater then 2krpm). and also for reference, i am sort of looking into different turbos and the GT35R was one i liked, but grated it makes sick power, i'm thinking the turbo lag is just to great for anything i will be using it for.

any insight is welcomed in my confusion over the dyno charts, and the more detail the better (retarded timing is the one thing i could think of to explain such "low" torque levels at 3-4krpm when "max" boost was achieved) and once again, congratulations of the impressive numbers
