420a crankshaft

[dsmeclipse99]

I have a 420a engine that I am rebuilding and I am planning on running like 20 psi of boost. The only problem I am having is finding a crankshaft that will be able to handle that. Will a stock crank handle that. Looking for Info. Thanks

Stock one will be just fine.

Yes the stock one will be just fine. The last owner of my car claims the motor made 700hp with a lil different turbo and fuel setup, And its still got stock the crank

Key CLAIMS....that hp record still has not been set for a 2gnt

Yea i know the the key is claims...But i didn't know that it would be a record thoughWTF. Once again he CLAIMS it was on a engine dyno with a t-67 with 175 shot nitrous. Which i doubt but i just said ok But if 700hp is a record for a 2gnt i might just have to start chasing that record some day

I would just tear drop and polish the journals on the crankshaft and have it balanced if you are that concerned about the crank.


GET in line for the record..look were i started out and you see were im at now!!

True..But I'm 15... top that! PM me And tell me what your using to tune your car if you would please. And to OP sorry for hijacking the thread but i think you got your answer

OP, you need to not think of boost in terms of power (alright, that sounds funny). What I mean is 20 pounds on a 14b does not equal 20 pounds on a 42r. I think you can see the difference.

And I believe that the stock crank will have no problems in either case.

(700 hp, heh heh)

Absolutely. Throwing around a boost pressure without mention of CFM (or turbine specs) is a sign of someone who doesn't really know what they're talking about. You don't build for Xpsi. You build for Xhp.

And 700hp. That's crazy. A good 100hp above the highest HP numbers I've ever heard spoken by someone capable of attaining them.

Everyone just wait till my car gets dynoed!!!

Yes i know about the boost equals X amount of weight i have tons of books on turbos and turbocharging. But i was just assuming he was refering to a t3/t4 or something along that size....BUT you know what they say about assuming its the mother of all #%^ ups

OP- Your crankshaft should be fine. Howell Automotive actually sells forged crankshafts for $400 or so if you are really apprehensive you may want to pick one up. Though I think it's unecessary, do whatever suites you.
