R1 crossplane crank

[Kentmagpie]

Anyone used one of these lumps in a BEC yet??? If so wots it like?? I've heard there not supposed to be great in front eng rear drive cars. They sound nice though :-)

[AdiT]

Not heard of any in a kit yet, though there probably are. They are lower powered than the earlier R1 engines but due to the nature of the power delivery, it's more usable in the bike. As I understand it, you can get on the power earlier without it throwing you off; I don't ride but thats how it's been described to me.
In a car getting on the powerisn't quite the same issue, so the x-plane advantage doesn't help like it does on the bike; You've just got less power...

[Kentmagpie]

That's a bugger, all I know is they sound nice but if it's poorer power than previous versions then it's a waste of dosh cos they're not cheap. Yorkshire engines said they're going for around 2500.

[Noah Katz]

Sure it's less max power but how often are you really going to take it to 10,000+ rpm, unless it's for the track?

It has more torque lower in the rev range, which is to say it has more power at street driving rpm.

Tbh it'd spend a lot more time on the road then it would on the track. Im defo considering this unit if anything cos of the noise it produces :-)

Noah Katz, you asked howoften do you take them above 10,000 rpm??

Ermm... at every available opportunity!! The sound is incredible.

I'd be interested to know the gear ratios of the cross-plane R1, I am sure the power will be enough to make the car rapid but some bike units have gearing quite unsuited to mating with a car diff. You really need to make sure your chosen unit coupled with diff ratio and tyre size will pull AT LEAST 125 / 130 mph or it will be too manic. You say it is notsuited to front-engined RWD, maybe somebody has worked it out already? Just check before you buy one, there are online gear calculators out there to do it on.

R1's vary dramatically, for instance Adi's R1 is the next generation from mine. His makes more power, revs about 2,000 rpm more and has about 15mph higher geared first gear. Both our cars drive fine but you do need to check if Yamaha have dramatically geared it different to make the bike safer for a rider which might compromise the car installation.

Spoke to ab performance yesterday and he told the crossplane engine in a car is **** :-( end of that then.

You cannot go far wrong with the fuel injection 5PW R1 (2003 version). Needs just a sump baffle and a powercommander and away you go, mine has done 33,000 miles so far with very few minor issues. Not sure the code of Adi's later one , think it is an '07??? Andy Bates knows them inside out, ask him directly what car, budget and you planned use and he will probobly reccomend a specific engine. I know he is a big fan of the later Fireblade engines, but they still ££££'s compared to around £1,000 for a 5PW Yamaha.

I had an 06 r1 engine in my last kit and loved it but just wanted summin different. Ab performance offer 08 blade complete engine package including everything for £3950 plus vat. Properly setup u can get 168 bhp at the rear wheels on a front engined car and 174 bhp on mid engined. Ab says its the best engine to use without a shadow if a doubt, RGB cars are all over them. If I had the dosh I'd probably do the same.

The cross plane crank r1 doesn't make more torque at all, its less than all the other engines. Its firing order alters the power 'pulse' from the engine making it apparently easier on bike tyres giving the feeling of a better/smoother bottom end. Put it on a dyno though and you can see its just a feeling.

Also if you look around you can get engines for much less than engine resellers sell them for.

For that sort of money i would consider a ZZR14, they can be run with a standard sump if you have the ground clearance ( i've got a billet sump as the car is to low for standard) they have more torque it pulls like a train, the perfomace doesn't suffer when you have a passenger. i can run a 3.14 diff so nice cruising RPM 5k at 70mph

As much as the CPC R1 does sound nice though!

I defo have thought this, my personal fav bike engine to use would be a zzr 14 lump. I just thought it was to expensive, am I right in saying that I'd be looking to pay at least £3500 for engine package and billet sump?? I've looked at a zx10 lump as well as u can pick em up for bout £1700 and don't have to mod em much. Seems like cheap alternative but not in the same league I know. If I could find a cheap bike project or cheap zx Bec then I'd look at converting to zzr power. The r1 cpc does seem far fetched considering it's mainly the noise that's good for that cash.

Maybe it's just the sound quality on that clip but to me it sound crap. I'll take my '06 over that.

I hit the rev limiter in my R1 Fury a lot on the road. What is the point of a superb sounding, high-revving engine if you are going to drive it like a diesel? You can use the acceleration on the road just fine.

This is a 2003 5PW R1 engine in Fury. Personally (I'm biased I know), I just love the sound of it:

You and me both, Rob. I have the same
