Flat Plane Crank - Page 2 - ZR-1 Net Registry Forums

Apparently balance shafts are needed to run a flat plane...

So, I'm learning something new. Never heard of a flat plane crank.
I've read the benefits are you can fire LRLRLRLR, or the reverse - odd-even ect. HOWEVER, according to Wikipedia, the fireing order of the Coyote is LLRRRLLR???

Sounds like more trouble than its worth depending on application.

efnfast · 08-05-2013

Seems like an awful lot of work for 15 hp.

LGAFF · 08-05-2013

Ferrari uses Flat Plane Cranks on all its Supercars....I think its worth alittle more than 15hp....move F1s run a flat crank.

Looks like they got 659hp from a 6 liter LT-5

So that's about a 360CI. What have we (really I mean you guys) gotten from our LT-5's at 6 liters?

I think you could get 560 or so out of a 368(keep in mind you might need a 2K idle for that Lotus GT-1)

So, you think you could get about 100 hp from this crank?
How come I find the Coyote to have such a stange firing order? Seems that's where most of the hp comes from.

I think I heard Loco just 480rwhp out of his 368 with stock cams. That's about 550ish crank, right. Put in a set Pete cams, I think you would be knocking on the door 600ish.
