Re: Flat Plane Crank
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??? |

Re: Flat Plane Crank
Sounds like more trouble than its worth depending on application.

Re: Flat Plane Crank
Seems like an awful lot of work for 15 hp.

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

Re: Flat Plane Crank
Looks like they got 659hp from a 6 liter LT-5

Re: Flat Plane Crank
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)

Re: Flat Plane Crank
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. |

Re: Flat Plane Crank
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.

Re: Flat Plane Crank
Haibeck Automotive Technology www.ZR1Specialist.com Upgrade path for a 368 ci engine: Adding Stage II cams should add 40 hp. With Stage II cams a loss of low speed torque is likely.
If the starting point is a maxed out 350 with 500 hp the added displacement will take the engine to about 530 hp. Adding Stage I cams should add 20 hp.
