Callies Compstar vs Dragonslayer........whats the big difference.......??? I plan to make 1,100-1,200 HP.
408ci iron 6.0L GenIII
94mm turbo GT-55
4L80E
3:23 gears (most likely)
Will the Compstar be just fine? 100% street car, it will never see a hard launch at a drag track. Roll runs only......and weekend use.
I was told the Compstar is made in China and finished here in the USA. Dragonslayer is made and finished here in the USA. More pure steel??????
Is that the only difference in the two crankshafts.....????
((and with all due respect to all here.....I'm really not interested in hearing...."How are you gonna hook that much power on the street?"......LOL.....thanks))

A friend use a Compstar in a pretty max effort NA gen 1 motor and had it crack at an oiling hole and due to a very good ear heard the bearing barely chirp making maybe one turn on shutdown. So he caught it before any serious damage was done, one rod needed a light touchup. Callies was very good to him on helping him upgrade to a nicer all American crank.
Having seen that occur in a friend's setup would stop me from using a Compstar in a boost setup.
I don't think it is a matter of just the quality of steel I think it is a total package of overseas lack of quality. Machining something here and inspecting it is better than machining overseas but does not make for as nice a total final product.

Yea, I just figured since stock cast cranks have been proven to 900-1000.....a forged Compstar would definitely handle more. But if they have been known to have manufacturing defects......no way I'll try one.
I'm looking everywhere right now for a 4" Cola....someone has to have one laying around. My 4.125" Cola out of my 427ci is just too much stroke for a 6.0L iron and boost.......
