Cooling a 750CC TSCC engine in a buggy

Hello Folks,

I'm a big fan of the GS, and especially the GS750 engine and decided to use one in an off road buggy. Unfortunatly, it's difficult to get sufficient air to the engine so I was wondering if I could use a much larger oil cooler (with forced air via fans) to compensate for the reduced air flow. It's hard to tell how much heat I could draw from the engine by installing a larger oil cooler. Does anyone know how much heat I could expect to disapate with a much larger oil cooler?

I was also thinking about running copper water lines through the fins in the heads and pumping coolant through them to help remove some of the heat from the heads.

I know running a water cooled GSXR engine would solve the problem, but I've gotten really attached to the GS air cooled TSCC engine.

I really can't answer your questions but you better post pics of this thing when your done!
And I thought my "Drank some beer and modded my GS"pics were nuts........
 
why not just get a electric radiator fan and place it in front of the engine??

also it would be a good idea to wrap the header pipes.
 
I would like to just use a few small fans with high CFM to blow air through the heads but the heat from my custom set of headers makes that difficult to do. Here is a picture of the GS750CC TSCC mounted in my buggy, and a few of the buggy itself. Ideally, I'd like to go with a 8x larger oil cooler with fans blowing through the oil cooler, but I'm not sure how much oil from the engine flows through the cooler, and how often it cycles, etc..

Wicked cool. I want one- with an 1150 motor in it!! And nitrous!

May I suggest a cage for the gas tank? Hate to see you roll it, tear the tank and have it leak all over the header. Very cool machine man.
 
Awesome man! Wish I had a workshop I could do that kind of work in.
 
Very Cool!!.....

But you forgot to fasten your seatbelt....:)

tHAT'S PRETTY DARN COOL. i WANT TO DO THAT WITH MY SPARE GS1000 ENGINE!

oops.:oops:

I'd make a fairing to duct air to the engine, as well as the oil cooler.
 
That's too cool! :-D

I don't see why a bigger cooler wouldn't work. Give it a try. Maybe some air induction, too. I'm not sure just how much oil goes through the cooler, but I know it's alot. I put a cooler on my 1000 and when I rev it up, I can see the lines pulse. Plus I think the 750's have a higher volume and run at slightly more pressure than most GS's?

Cool toy. I hope you get it worked out good.
 
Wow, that is amazing. It's my dream to have a shop (and the skills!) to be able to make something like that.

If it were me...

If it's possible, re-route the exhaust above the engine, allowing more direct air flow from fans mounted behind or beside the seat.

A ceramic-coated exhaust would probably help too. And carbon silencers tend to radiate less heat than metallic ones.

The oil-cooler idea is excellent, and there are lots of walk-throughs on this site explaining how best to install one.
 
WOW!... now that's super cool, you must be proud. There's no way I'm going to show my Daughter those photos. I have enough trouble already:-D
 
One thought (that buggy's on my mind WOW!)...... In my Kart-Racing years, we used to have a digital Exhaust Gas Temperature Gage (thermocouple in the exhaust gas stream at the header) and a Head Temperature Gage (a ring-type thermocouple that replaces a plug washer) and one digital display unit. May be a good thing to have and to keep an eye on the engine temp regardless which means of supplimental cooling you opt for.
 
I just watched the video. I'm not sure who had more fun, you driving or your wife videoing/laughing.
 
How about a 12V blower like from an auto A/C unit a short duct and a little fiberglass cowl to direct airflow. A relay and thermostat can be easily rigged-up to switch the blower. Of course, if oil cooling brings the temp down enough , then, that's far more elegant.
Just got the video downloaded, what can I say..... A W E S O M E!
 
thats pretty cool, i use to have a suzuki quad that i put a gs450 motor in and it hauled. as for cooling, how about those nascar brake cooling fans. there 3 inch tubes that just pump out air. there 12 volt so it could work. they have them on ebay.
 
Thanks for all of the complements!

I like the blower motor idea --thanks! Since I'm not running the headlight, does anyone know how many amps I can safely use for 12v blower motors without risking damage to the voltage regulator/charging system?

I'll take a look at some 12v blower motors, and also look into maybe welding up some alum duct work. I'm thinking maybe one blower motor for Cyl #1 and #2, and another blower motor for Cyl #3 and #4.

That baby looks awesome!

I notice you have to shift pretty quicky with that - did you consider some other transmission? Would it have been practical to go with one of those variable diameter pully designs with a GS engine? A CVT with 60-70hp behind it would make for heckuva cart...
