Bums to Bonniville- gsxr 750 turbo

[Bigredzed]

What i was thinking about is using something to spray the intercooler besides window washer fluid or water that will absorb a lot of heat by vaporizing- latent heat.

Water has the highest specific heat capacity of safe to use liquids. Ammonia is higher but you don't really want to be squirting that about

Thought of something today--> ideas on cooling the air charge after the intercooler using refrigerant ( freon )...i would have to build some sort of heat exchanger for this. What about a surge tank with small 3/8" tubes running through it with a chilled refrigerant charge in them? CAn anyone see any issues with that?
Id fill up a liquid receiver with R22 for instance, use a temperature actuated solenoid to open at a preset charge air temp,releasing the refrigerant through a metering device to control the temperature of the liquid, and have it travel to an other evacuated cylinder to catch the charge. Air temp going through the liquid ref/air heat exchanger will assist greatly in boiling off refrigerant and will assure all the liquid is boiled off ( i think ). Going to do the math to see how much refrigerant storage ill need to sustain approx 60 seconds of chilling. Anybody have a actual temp for exiting air out of an intercooler at say 90F ambient?

anybody know where you can buy liquid nitrogen? :razz: that would sure cool shit down in a hurry haha

Anyone ever done any sort of experimenting with liquid propane injection? that stuff burns good, and doesnt it have a decent Btu/lb rating? If i could inject propane it would certainly lower the temperature of the air mixture, and it would burn- hopefully not sucking any power out. Anybody have any pros/cons to propane injection.. or compare it to pros/cons with NOS?

Storm has two liquid-cooled intercoolers, one is a conventional chargecooler (Pace style) and one is a laminova cooler. Look that one up, but let's not try to run before we can walk eh?

good point.. ive got a long way to go before worrying about that stuff.
how about a 'walk' question then: when sizing the throttlebodies on a bike for top end power , would you go bigger then stock or keep it stock ( when turbocharging )? what are the pros and cons to having larger throttlebodies?

[Lorcan]

The way I view that is to look at the outlet size of the turbo, and the size of the inlet valve. IMO all the pipework between the two should be slowly reducing in size from the turbo to the valve. You don't want any big size changes either way at any point as this impedes flow. Allow for the fact that the TBs have butterflies in which reduce their effective size.

I have been pretty busy latley- built my Megasquirt and stim board and all checked out very well. I had a set of gsxr 1000 tb's modded to fit the spacing for the intake boots and slapped them in the other day. Bought all the required sensors and made a wire harness for it and borrowed the fuel pump and regulator off my 750 turbo-> and to my surprise had a fairly easy time getting it to start and run smoothly at idle It even revs up nicely on the afr and v/e table i have in it which was a total guess. :rockbanana

hi all and lorcan,its been a while since i last posted on here,we built a 500cc bike last year and ran at bonneville in august at speed week,the 489cc motor was based on my fzr500 drag bike setup,we managed 203.3 average,with around 210hp,which is not bad for a 500cc non streamlined bike

Nicely done Sir.

[hodgeiom]

we found that running a Bonneville was quite a challenge,over 4 thousand feet altitude and 46deg c air temp,takes a good setup bike to run fast speeds there,the first thing I did to the bike when we arrived was remove 7% fuel from the whole fuel map,this could not be foreseen setting the bike up in the cold and wet isle of man.

[Lorcan]

That's excellent Hodgie! Did you go with the mob that were on TV? How come you didn't get on the show? Go too fast?

Update!

So it’s been a while. Life has happened, fun things and bad things.. but I did end up making it to the salt in ‘19. I decided to run in the open class with my bike and it’s setup and wring it’s neck out to see if it would survive. It did! And I managed to progressively work up to a 184mph run which was good enough to take the AMA record. I met some amazing folks on the salt, and my neighbour in the pit’s has agreed to help me design and built my streamlining so I can enter the class I really wanted to go into in the first place and break that 225 mph goal. One of these days I’ll be back down there and see what me and my bike can really do.. I was limited to the short/intermediate course until I passed 175mph. Which I did on my last 2 runs. My last 2 runs were the only time I reached full throttle ( looking back I was probably being overly cautious). With the long course ahead of me, and a whole heap of learning under my belt, I think 200+ average speed over a mile is realistic.

So far I’ve only turned the boost up to 1 bar, and made something in the 200rwhp range. Using std correction method, slightly closer to 190 with no correction.

Thanks all you beautiful people for your support and honesty back in the 2012 days! 2020 and 2021 have shot my racing dreams in the balls.. hopefully 2022 will be better!

I salute you sir!
Getting a bike and a team to Bonneville was on my bucket list.
Getting a bike and tem BACK to Bonneville is now on my bucket list.
Not sure if anyone ever gets back from the salt and says " no need to go again as we can't do any better", the constant niggle of things you should have done and didnt do causes an itch that needs a scratch.
To quote the Blues Brothers - We're putting the band back together. (at least i want to although I may have to sell a kidney to do so).
its a special place - make the effort before the yogurt knitters stop it happening.

Well done sir

[Charlie @ Evergreen]

Well done for sure as Mang says!

It was on my bucket list also until a bad thing happened 2016.

Mang if you make this bucket list plan I want the dates as I will come to the Salts to be there with you all !

[Mang]

Charlie I need to rob a bank and find about 1 year of free time but we will return, hopefully without gremlins. I hope many friends can come - its great fun. Darrel is up for it and the UK contingent are saving up.

[Charlie @ Evergreen]

Looking forward to going!

If can do anything to help out will do it. Even get you tea!
