Post by sam on Jun 18, 2013 9:48:56 GMT
Firstly I'd like to say hello and introduce myself
I build and race TL1000S's, specialise in them and build many customer drag and race engines, some my recall my 200bhp supercharged TL1000S in Performance Bikes mag a few years back, nowadays I race a bored and stroked 1200cc TL in the UK National Hill Climb Championships.
The reason for my post is that I've had an itch to race a Hill Climb Trike and finally tracked one down unfortunately in a rather sorry state at the minute, minus it's engine.
It was built around a GSXR1000WP engine. I am toying with the idea of eventually fitting a Hayabusa engine but for now it makes sense to go for the easy option until I decide it's the bike for me.
Although very clued up on TL engines I'm clueless about the GSXR engines and their evolution.
The water cooled GSXR1100 engine are fairly rare now, so I'm trying to open up my options by seeing what other engines are a bolt in alternative by sharing the same engine mount positions, ie 1200 Bandit ??
I want as much power as possible in stock form as I don't really want to be getting into engine rebuilds/high comp pistons/big bores just yet as that's money out of the Hayabusa pot....
Any info on cam swaps, carb swaps etc from other models to increase power on the earlier WP or between engines ?
Any help would be greatly appreciated
Regards
Sam

Hi & welcome. Not sure on bolt patterns matching from WP to 1127 ( Bandit ) But I seem to remember to LCR side cars ( the ones that raced along side the GP bikes in europe ) using WP motors tuned I guess but there not short of HP stock. Someone might have some numbers HP wise. TL Looks mint. Do you race at the likes of Prescott.

oilcooled, early watercooled GSX-R and Hayabusa/GSX-R1000 are completely different engines, with different engine mounts. If the trike is built around a wc1100 engine, then a Hayabusa will probably also fit in the available space, but new engine mounts will be needed. The oilcooled engines (B12 and GSX-R) are quite a bit larger than a wc one so it might not fit in the hole.
And the Busa has the throttle bodies and airbox more above the engine so you might get some ergonomical problems.

Higher compression helps, but I guess that isn't in the budget. Later cams are better than the early ones (specifications are in the workshop manual). You could dump the alternator, and starter motor to save some weight as the power draw is small (even if you have a fuel pump). You can bodge the trigger wheel to get a few degrees of advance. Airbox mods don't help much. rf900 head is supposed to be a good mod. Different carb options available with the expected different advantages and problems.
Maybe just ride it an enjoy.
Regarding engines with similar packaging. lots of similarities between gsf1250s and gsxr1100wp, but the gsf isn't tuned for power. You might be able to get as gsxr head to fit (couple of through bolts in slightly different places to prevent people putting the gsf bits on back to front). Cam chain in centre on gsxr1100wp, after that the cam chain went to the end and there was a revolution in lightness.
You can pick up gsxr1100wp engines, they are still around and are very solid lumps so why not just keep an eye out?

Thankyou guys, for now I am searching for an 1100 engine, may even decide to look for a bit more power from that in the long run :-)

sam the tl looks aesome , the trike outfit looks mental . should be able to pick up a wp1100 full running bike cheap enough as they dont have the following of the earlier gsxr 1100 oil cooled .

Sorry should have added
rf900 has same mounts and offers much interchangeability (though less power), but maybe puts you into an easier class? Similarly gsxr750w will fit.
3 gsxr1100wp engines on e-bay at the moment. The complete kit at £800 will not sell at that price because no-one (actually 3 people worldwide as far as I know) puts these engines into kit-cars.
Lots of people with spares on here, so just sing out if you need anything.

I used to road race an RF900 many years ago when money was tight, pretty quick but the hydraulic clutch slave would somehow suck in a glug of air after the start and be useless for the rest of the race, great fun though !

It's started, already getting distracted by 1195 JE pistons.....I buy a lot of JE TL pistons from Paul at TTS....
There is only one class for the trikes, anything up to 1300cc, and they can be turbocharged or supercharged too
So makes sense to aim for the most competitive engine allowed ideally.

Not sure that going big bore is a great idea on these engines. It leaves very little gasket surface which can be a problem and leaves you no-where to go.
1146cc seems to be a nice place to end up.
Sounds like you have the bug. You will be EFIing and turbo-ing before you know it!

On a side note this is the supercharged TL I built in 2010

That TL makes a mad sound. Top job fella. The w/c engines are very tuneable, some very silly motors used in grass track before the rise of the busa motor. I've had a few, go well as stock, better with big bore (160 rwbhp and lots of torque), mine ran 168rwbhp with cams/ big bore. Keep the redline stock and they are strong motors..
