Crank recommendations: 8000+rpm/700+whp

project_skyline · 09-05-2010, 11:50 PM

Alright so I wanted to see what everyone thinks is a good crank to run for a car that will be running higher rpms and high horsepower. Probably 8500-9000rpm wet sump system and 2.5L

The most important thing is strength and oiling.

Price is a factor as well.

If you think the stock one is good, list any modification you would do for making it reliable for the above.

Thanks!

either stock with a modded oil pump and bigger pan or a manley billet with the same mods.Either crank will do the job --stock crank=350.00 manley billet 1200.00 you choose.

Homemade WRX · 09-06-2010, 11:25 AM

so you're aiming for 700+ on a 2.5L and price is a factor?...ok

in that case, get a billet or don't plan to spin much past 8k on the stock crank. You will want to make sure you have the clearances on the main and rod bearings just right.

Lol its a factor but that doesn't mean its an issue!

What billet crank would you suggest?

Junior2JZ · 09-06-2010, 02:11 PM

Arrow and Cosworth are the 2 best IMO.. The Manely one is a nice piece as well. I will be running the Manely in my spare short block along with all the other parts they offer. PM me if you want more info on it.

I will be running an OEM crankshaft in my build with a P&L modified oil pump. Looking at 8500RPM to a maximum of 9000RPM. Looking I've been reading that the OEM crank can take a lot of punishment before you have any issues. Capable of prob about 700hp.

When I was looking for parts for my build, I was told by AMS that they offer three options for cranks: OEM, Manley and K1. Manley and K1 both make a solid product that are both roughly $1500. I can't really justify buying a cosworth crank and spending that kind of money when you could get something as good for half the price.

Arrow would be my first vote because of how they route the oil through the crank.

All the rest are pretty much the same layout 'direct shot', 'straight shot', yada yada

...never really handled or looked into a cossie crank.

Arrow and Cosworth look exactly the same.. I mean identical!

Could Arrow be the manufacturer of Cossie Cranks?? I have one though..

they were for Cobb's billet cranks, so it wouldn't surprise me.

Texy32 · 09-07-2010, 04:37 PM

Yes arrow makes cosworths cranks. It has the same
oiling set up as the arrow design. Very nice piece but for the
money I want the new 83mm Manley crank for $1200.

RacePartsGuy · 09-09-2010, 10:10 PM

Manley's crank has the same cross drilled oiling system as the Cosworth/Arrow for about 1/3 the cost. They are by far the best crank available for the money.

RacePartsGuy speaks the truth. I spoke with my Manley man today.. he confirmed it.

proof is needed!! are you sure it isn't just a straight shot like the BC setups?

Mr. Homemade, I can arrange to have both cranks side by side.. Any particular shots you want?

DSM_Outback · 09-10-2010, 01:02 AM

Teh Money Shot.

charliew · 09-10-2010, 11:03 AM

I think he wants the pictures that show the oil galleries exactly the same in both cranks at the same view.

I'm just stoked that they are doing it the right way at an 'affordable' cost.

The original arrow design doesn't send the oil across the main journals and actually runs them parallel to the crank. Requires loctiting and plugging set screws in the ends of the oil journals.

Searching for a machine drawing of it on here...I know I have it saved on one of my computers as well.

Awesome, I'm stoked but no rush. If you could, can you please stick straws (or something) in the oil passages? makes it easy to see where they go.

I've already founder better than that but none give enough detail to show what i'm looking for.

So if I want to do a 500WHP maximum build I could just use a 12200AA400 stock crank?
