Pan Euro Engine Weight
Hi Guys,
I'm new to the site - so hello! I joined because I really like the can-do attitude and because my on-paper-project has probably got more in
common engineering wise with the 'book' project than anything else on the net.
I'm looking at drawing up a space framed reverse trike and I'm looking at potential powerplants. Two potential engines I am looking at are
the Honda ST1100 and ST1300 V4s.
The only people I have seen transplant these motors into a car are here on this site and after a fair bit of searching I haven't found my
answer, so I'm curious to know if anybody knows what these weigh in at (inc gears, clutch etc)?
Any ideas guys?
Also, for my own personal amusement, is there any video footage lurking about of a Honda V4 Locost? I'd love to see/here it actually in
action.
Thanks a lot,
Conor

Hi Conor
I can't help you with the weight of the Pan V4's, but I suspect they will be a good bit heavier than your average bike-engine.
Not the be-all and end-all of course, but the ST1100 / ST1300 engines only make 100 / 125 bhp, so worthy of consideration.
If it HAS to be a Honda ST V4, then I would swing towards the ST1300 as the 92 ft/lbs torque it makes should compensate a bit for the relatively low
bhp. The ST100 only makes 79 ft/lbs.
I flirted with the idea of a Honda V4 for my reverse-trike, but eventually settled for an Aprilia RSV-R V-twin. Light, 140bhp and dry-sumped.
Good luck with your project.

Hi there,
Welcome to the site (or the madhouse as more commonly (accurately?) known!  )
Sorry, can't answer your question but I know a man who might! If he doesn't spot your post then send a u2u to BenB as he uses this engine
type I believe.
Hope the helps,
James

Hi,
Thanks for the reply. Part of the reason for the longitudinal V4 is packaging - I'm building a front engine RWD with a bias towards good low
drag aerodynamics. The V4 squeezes up front quite nicely giving good room for a sort of recumbent seating position, and the shaft drive helps with the
layout.
Also, from the cobbled-together quasi-research I've managed, it's flattish torque curve gives pretty good fuel consumption over a broad
range. Reducing fuel consumption is somthing I am very keen to achieve with this design.
This is basically why the Pan appeals to me, but I am by no means dead set on it. Other engines and options are always considered.
Thanks for your help,
Conor

Whilst not the most powerful engine, what a lovely smooth drive it would be.
Kindest Regards,
Richard.

pan euro engine
My ST 1100 engined phoenix was on the rolling road last week (finally got it something like!) now jetted about right but the gearing is a bit of an
issue- flat out 8800 revs -100mph so I now need to check out the Sierra Diff ratio (thought it was about 3.6/1) .I thought the engine was around
95kg??- my car comes in at 540kg less driver.
cheers Dave

Pan Euro
The only kit car maker I know who worked with the Pan Euro engine was Stuart Taylor, which is now Aries Motorsport, they had a test bed using this
engine and it had two sets of carburators. Very fast through the gears with an overdrive crusing gear when in sixth. The only problem was it is a
very tall engine.

Hi Guys,
Thanks for the info. BenB came up with around 85kg so 90kg seems to be the ballpark.
Interesting to hear about Stuart Taylor trying other carbs. I was wondering whether I could play with alternative carbs. Might be able to make
somthing that makes the induction set up a bit lower - anybody know just how hi it is, from pan to top of rocker covers and also from pan to top of
airbox?
Thanks guys,

ST1100
Checked last night...engine to top of cam covers is 22 in, the carbs and plenum add another 6 in and mine has an ITG sponge filter on top of that -
another 2.5 in. Hope that helps Dave
