im looking for a crank to handle high horsepower high boost supercharged motor.
i been pointed towards callies cranks. any other cranks that are good as well?

 

Are you wanting a billet crank or a forged steel crank. I have an LA enterprise billet crank in my motor and it should handle 2000hp if I want to make that much. I have heard that a forged crank can handle 1000hp or alittle more but that's about the max. Callies are very good crankshaft. How much HP are you wanting to make? I am making 1000hp or alittle more and I know the billet is alittle overkill but I plan to upgrade in the futher and hope to pump out about 1700+ with a turbo. I have also heard good things about Cola Cranks and a bunch of people use Eagle and Scat cranks. But I think I would stick with the Callies crank. Just remember you get what you pay for.

 

im looking at around 5-700 supercharged

 

Callies forged steel crank will be fine. Just get some Eagle H-beam rods and some JE or Ross forged piston and you will be set with the bottom end. What cubic inch is the motor going to be and what cylinder head are you going to use? Sorry for all the question.

 

355 and afr's

 

I don't think it will be that hard to hit your goal since it's boosted.
Good Luck with it.

 

yea. i have absolutly no doubt about reaching the power goals. my worries lie in blowing apart the motor with so much power.

i was at www.flatlanderracing.com i think it was and they have callies dragonslayer cranks for $729. which is the best priced callies crank i have seen. and is at a price i can afford. any thoughts on this particular crank?

 

I have not heard anything about that series of crankshafts. But I am sure you would not have any problems with it. Maybe someone else will chime in with some info on that series of Callies cranks. I would also like to know because I might use one on my next motor. Let us know how everything works out.

 

im not sure about anything on them. the callies website doesnt list them. and on that site it says they're new so i have no clue. but im assuming its good because its a callies crank. and at $729 you really cant beat it.

they got a lil write up about the dragonslayer in that article. i guess the dragon slayer is a slightly toned down version of the racemaster.

if anyone else has any opinions or info on this line of crank. dont be shy.

i also found that on a message list i got off google. so if thats true then the dragonslayer is a pretty damn good deal at $700.

 

callies, ohio crank shaft, i beleive sonny lenard makes them, and lunati. you could check with patterson or nikens bros., they both ought to be able to hook you up with one

 

Whats the difference between Forged and Billet? Sorry, I'm not that great at specs.

 

i got no clue lol. thats why im asking the questions
