triumph 1200?
Not my usual area, but a very good friend has just bought an engineless fury and is on about a 1200cc 4 pot triumph engine that you can get dirt cheap
apparantly.
I'm not even sure what model bike it's off as I thought (from my limited bec knowledge) that all triumph were 3 pots, does anyone know
what engine this is, and got any specs/figures/gear ratio's for it? It's a live axle car so need to work out dif ratio's etc (yes
i'll look up the calc program, jsut need to know what the engines box is like)
I appreciate its obviously not frequently used and it may be untested in terms of the normal bec installation issues such as sprocket adapters, surge
etc etc. but any useful info appreciated.
thanks,
Ned.
beware, I've got yellow skin

Hi Ned
Triumph did do a 4 pot 1200 supertourer, was it the Daytona?
It was a competitor for the likes of the ZZR1100 I think, and so would have kicked out decent power (~140bhp or so probably) but as you say he'd
need to check out gearing etc. Also tell him to work out the total cost of install, not just the engine cost. Due to being an unpopular BEC engine,
the other bits like the prop adapter you mention arent available off the shelf so will often cost a fair amount more to purchase, thus lessening /
negating the cost advantage. Also he needs to think about being a pioneer and the possibility of maybe blowing up one or two engines before getting it
right if it happens to suffer from oil surge etc.

would imagine it will be a speed four, or 1200 daytona engine,have a check on here link in the forums, will give you an
idea of known faults etc with the engine

Hi Ned
sounds like a trophy, from what the reviews say this should make a stonking car engine as the trophy is a cruiser so lots of mid range grunt !

Hi I'm putting a triple in the barchetta
I believe they were based around the zzr block.
I don't know alot about the four but the triple is good for 140bhp but they are a little heavy compared to the R1
Good torque figures and a great noise but don't tell everyone as they are cheap as chips and I'd like them to stay that way

Hello , ok so im new here,and I know this is an older thread but Triumph Bikes I know. The 1200 triumph lump (actuall size is 1180cc) its either a
Trophy early ones had around 125bhp later models 100bhp or a Daytona which has 146bhp . Ive had two Trophy 1200's and Ive currently a Daytona
1200 sat in the garage which ive ridden all of 6 miles ;( The Trophy engine is tuned and geared for mid range and has buckets of grunt. If you phone
the Triumph Warranty dept at the Hinkley factory with the engine numbers they will be able to tell you what it is

Welcome Stef. Do you know the red lines and gearing for the bikes because that will also determine if they are useable in cars, as the diffs we have
available are limited so if a bike engine is too low geared or has a low rev limit, we'd struggle to get a useable top speed.

with the daytona figures quoted abouve, with 195/50/15 wheels and tyres, with a 3.14 sierra diff (the lowest available) these are the top speed in
each gear at the 9700 red line
1st 42.4
2nd 59.5
3rd 75
4th 90
5th 100
6th 108
with 70 MPH being at 6200 RPM
with 195/60/15s the speeds are
1st 45
2nd 63
3rd 80
4th 96
5th 107
6th 115
You could resort to 17" wheels to up the gearing further, especially if you can't find a 3.14 diff. I would want slightly taller gearing
that this.

There lays the problem it would seem, as the figures show its very hard to get it geared sufficiently high to give a decent top end because of the low
primary drive ratio and relatively low red line. Even if you go for 17" wheels you're going to need relatively high profile tyres on them
to raise the gearing much above the figures you see for the 195/60-15.
