Stock Or Stroke It?

[mybadbanshee]

im in the middle of a tear down and cant decide whether or not to put in a stroker crank or stick with stock and spend the money on other parts.Is the power increase that considerable?

[ranshee]

Do you have good suspension Already?

[mybadbanshee]

no

[ranshee]

Save the money for suspension. Theres no point in all that power with know way to controll it. Thats just my opinion, But its your choice.

Great point.

 

If you have a good stock crank, you can have port work done to your cylinders and gain considerable power. If you plan to stroke it later, let the builder know so they don't "over port" then engine. I have a stroker, but that's because my crank went.

my crank hasnt gone yet but i figured while i was in there.....well you know but now that ive been thinking about it.theres a lot more i could use the 550 for.what other work do you have to do when you go with a stroker?

[ranshee]

Carbs, intake manifolds, Maybee a cool head.

Carbs, intake manifolds, Maybee a cool head.

also add some type of air filter system and most likely a clutch. You'll need port work too. You'll have to have a spacer place or have the stock head cut or domes cut for the 2mm increase in stroke.

 

It's a lot of $$$

True that, the stroker doesn't stop at $550..You have to get larger carbs, different intakes, and reed cages to match...W/o the intake changes the stroker can't get no where near its potential.....not even half....so now your looking at $1500 w/o porting....

A complete stroker package including 12 port porting and bore, +4 crank,seal kit, pistons,plate, Noss head, 34mm intake,v-force reeds,34mm Keihins,cable, intake boots and Barnett clutch will set you back around $2340.00, definately a chunk of cash but considered a bargain in the world of horsepower...Jim

how much hp are we talking about ??

[PassionRE]

Non drag port or case mod versions will produce a very broad power band with great bottom end and mid 70's Also, this would be considered a very reliable engine, not a radical version...Jim

Mine dyno'd at 79.5 peak hp with Jim's motor

[fixitrod]

But, you have to remember the usuable power is the most important part. Sounds like Jim shoots for usable power... not just rpms and power.

 

I would like to see a pic of the dyno Schizo !!!! If you don't want to post it, email it to me at [email protected]. If you don't want me to post it, just tell me and I won't. Thanks A Lot.

Actually i do not have a print out i dont think they had it hooked up to a printer...but i did get to look at a bunch of graphs form it and it peaked at 79.5 with 45 ft lbs of torque and they claimed that they tweaked with it for 2.5 hrs. When i took it to them it had 3 1\2 inch runners going into a single k&n filter with 175 mains and 42 pilots and the base run on the dyno was 71. They went to k&n clamp-ons and leaned it out to 172 mains and leaned the needle with CGL needles and bumped the pilots up to 48's and got it to 79.5 hp. When i took it out for the first ride after this it ran like shit, i went up to 178 mains and back to stock CEG needles and it runs awsome, better then it ever has so im guessing im still up in the high 70's for hp.
