How are you getting the drive to the wheels???

FJ1300 engine perhaps?

Shaft drive.

touring bike, FI and 145hp and 130(ish) torque developed around 8000 and 7000rpm respectively.

no idea what it revs to but it would be interesting fitting it in a right hand drive car due to it wanting to be where the steering column is.

(guess who looked up the web site!)

It's perfect for we Yanks. What website did you find the info??

--Chris

did a search on the engine name, found out it was a yamaha then went direct to the yamaha web site. Realised it wasn't a sports bike so looked up touring sports ..... hey presto, bob's your uncle, fanny's your aunt and hey diggedy i got the details..........

although that is all there is, its very scarce, no idea of the red line but it does have a 5 speed box.

yep and I seen the car revirsing it is sweet good simple Lenny

Did this thread have links to the drive unit? I'm sure someone posted a link but can't find it?


Cheers

Isn't the FJ the same engine as used in the Legends Racecars?


Legend Racecar - MPH04

[Edited on 24/2/05 by stevebubs]

i thought those guys used the fj1200 engine,not sure
the fjr1300 engine is a beast of a thing,im sure it has a redline of 10500,for a big bike it realy is quick

i thought the legends use an air cooled engine - which gave them problems with over heating if not careful due to enclosed body.

Seem to recally Dave Andrews (DVApower) mentioning something about special exhaust valves to help with the temperatures.

(as usual with my posts these days, this is a vague memory and should not be taken as correct)

yip i think the early fj 1200 engines were air cooled

Two engines? One in the back too perchance? AWD?

Just speculating ...

-Sven

going back to the picture of the blue car, can they not get the engine any further back? Seems very far forward to me

Looks a very neat installation!

However...

I thought (as for the yamaha Vmax engine) shaft drive bike engines which have the shaft on the left hand side of the bike turned the wrong way for most diffs?

Then the reason why BMW shaft drive engines can be used ok is that on the bike their shaft is on the right, so turns the correct way.

Does it run with the diff turned over?
Also - is there much power loss with the big bevel gear turning the drive 90degrees?

I need more photos
I need more specs (diff, reverse,...)
Living in a LHD country I'm liking this...

Although I suspect that this engine, as being so young, won't be that cheap...

I'm resurecting an old thread.......
Anyone have anymore information on a Yamaha FJ engined car? I heard the legends cars use them with Toyota rear axles and custom ratios all the way fronm 2.5 to 4.1.
I wonder what they are like in terms of reliability etc in a car????

charlie is that the same engine that you caught me out on last year when i spent 10 minutes trying to puzzle out how you'd get drive to the back wheels
tony

Bump to top........

Anyone anymore info on this engine? Same torque as a busa. Shaft -drive on left side so suits us LHD folks. Does the shaft spin the wrong way for a reg diff?
Thanks
Rob

sgraber knows quite a bit on this engine. Send him a U2u.

--HTH, Chris

Cheers Chris, will do..

Strong Engine. 150Hp and Certain years have a propensity to loud ticking from the valvetrain. Very loud ticking. Should you decide to use one of these engines, you need to hear it running first to ensure that it does not have the "tick".

The shaft output has a primary reduction of 1.5630

The gearbox is sequential 5 speed with the following ratios

1st : 2.529
2nd : 1.773
3rd : 1.348
4th : 1.077
5th : .929 (overdrive)

When used with a tire dia of 23.25 inches and a final reduction (diff) of 2.9 you will see a top speed of 148Mph

Here is a website with more technical info:

Thanks Steve,
I might look into it. The miget/funny car crowd do all sorts of diff ratios and stuff for the toyota rear axle so maybe they have something suitable to allow for the drive spinning the other way....
Probably a hard engine to find though
Rob

Spoke to someone the other day about running a diff the other way. As it turns out, people get confused. The whole axle is flipped over. The gears still turn against the preferred side, not the coast side. I tried it with beer bottle tops!
The only problem is the pinion is higher up and out of the oil. I don't think it is a problem, what with oil getting sloshed around everywhere. Thats my theory anyway....

Rob

You are comparing apples to oranges. In the situation you describe, the input shaft is still spinning the right way so indeed the drive is against the correct side. You flip the diff upside down and the wheels will turn in the opposite direction. But in the case of the reverse rotation engines the input is already spinning bacwards... The diff needs to spin backwards AND upside down!
