Joseph's bikes and 1400 turbo build

[Joseph]

Thanks 

Another little piece of kit was finished, this is a classic on bike engined cars, nothing new here, but it allows the gear linkage, which will be push pull inline with the car, to be converted to follow the gear linkage on the bike, since the engine now being longitudinal in the chassis, is rotated 90 degrees in relation to the gear stick travel

Right one goes to the bike engine, the left one goes to the gear lever

Joseph, maybe something to help? Tripod been building bike engined cars for a long time. https://www.google.com/url?q=https://www.tripodcars.com/&sa=U&sqi=2&ved=2ahUKEwjE84ewoqyCAxVLr1YBHay4BRsQFnoECBcQAQ&usg=AOvVaw3zxFAxoUtLRgHvqGULgJAF

Just love that GSX1100 Joseph

[Joseph]

I'm back !
Haven't given up (yet) 

Jobs done or one the way :

Bought the turbo :



Holset HE221W is definitely a current trend. It spools quick and is good for up to 350HP

The plenum is finished :





However I'm very disappointed in myself, there are load of things wrong with it so it'll need redoing unfortunately 

I converted the PAIR caps into a turbo oil catch tank :

Brass spigot tapped in for the vent :



I hand filed an alloy sandwich plate because it needed to be increased in capacity a bit, and also provide substance for threading/screws. Because the caps are identical, if flipped over the holes don't line up, had the caps been symetrical i could have flipped them over top to bottom and could have just bolted them together





Done :



Oil entry on the top + vent, oil exit on the bottom, drawn by a mechanical scavenge pump i'm currently sorting out

Alongside that i've been busy on fitting the turbo and the exhaust system post turbo



Thats almost done. Onto the header after that (bit more of a complex job)

A Toyota MR2 intercooler is also getting modified to suit the layout :





That's all for now

Never missed you 






But that is because i visit the other Suzuki forum too

Looks very interesting, just thinking about the motor turned that way, these lumps are supposed to be hanging out in the wind, this one is sideways, so, even with good airflow, back cylinders won't get anywhere near the same cooling effect of the wind as a bike or indeed the windward cylinder. 

[Joseph]

Good point. It is indeed not ideal but i think that as long as it doesn't get stuck in traffic it shouldn't do too badly, originally the car has a big NACA duct on the front to guide air to the water radiator (now absent of course), the GSX cylinders are inline with that flow.

The oil coolers (two of, parallel fitted) will not be in the engine bay or close to the engine, also a cylinder head oil cooler is going to be installed, so hopefully the running temperature should do okayish i hope, if the oil itself is kept in check

Not sure how i can measure the differences in  the point that you mention, but as far as helping goes, maybe adding a duct from under or somewhere via a tube to the back cylinders? Not much room to do that but maybe i can come up with something

[Hooli]

Could you add more twist to the duct so it hits the engine from the side? Then an exit duct sucking out the other side?

[Joseph]

Well as it stands there is no pipe, the duct is 30-40cm wide in the middle of the car below the windscreen.

It goes straight into a vertical waterfall type drop where the original water radiator goes, sitting just in front of the fan > waterpump > engine.

I've ripped all the factory stuff out, so it's going to go : duct > "chute" > intercooler > GSX engine side fins/cylinder nº1.

But I might be able to fit an air pipe from an auxiliary NACA duct, from the side of the car directly to the back two cylinder area

[Hooli]

I'm mostly thinking that uneven cooling across the barrels could result in the hotter cylinders overheating with your configuration. I guess as you've gone to carbs you could run the rear two richer to help, like people used to do with the middle cylinder on Triumph/BSA triples. But that's always seemed a bodge not a fix to me.

[Joseph]

Yes that indeed could be an issue waiting to happen. Can't knoW until it's tested on the road though, if i can get air easily to the rear i'll just do it straight away before i get it driveable

I know for a fact that the first watercooled GSXRs standard have bigger main jets on carbs 2 and 3, not sure about the oil cooled ones but I guess it's possible they do too

[Hooli]

I didn't know that about GSXRs, but it makes sense for the same reasons.

Joseph, my 14 always runs cool, even on our extremely hot days rarely shows over 80 degrees. Maybe an electric fan behind barrels?
