Streetable setup....

[BIG GUY]

Was wondering what kit would all you turbo gurus recommend for a streetable setup? The bike is ridden on a daily basis and if you haven't heard it does get a little hot here in Phoenix. On that note, would it be best to have an intercooler installed? What hp number should I shoot for? I do weigh 360lbs and stand 6'2" if that matters.

I would say an RCC stage I. If I did it over again thats who I would choose. Its always better to have an intercooler on a turbo setup but may not be needed. Kind of depends on what your goals are. Your hp numbers are up to you, shoot for the sky if you want. I think 250-300hp is a good number to shoot for but really thats up to. Good luck!

With that heat..get a supercharger.

we turbo'd lots of vehicles in the Phx area... heat is only a problem if you beat on the thing a lot (at least on cars, HP makes heat, keep the power down, the heat stays down)..

That in mind, with ambient temps often over 100 degrees 100 days or more a year.. water injection or an intercooler are really a good idea.. We intercooled virtually every application with boost pressures over 1/2 bar (about 7psi) 300-350 degree air was pretty common when pressures started to go up..

Also a big fan of oil accumalators to keep the turbo with oil after shutdown (coking problems solved)

[GPW]

If your not going to beat on your turbo time to time...stay stock and get a nice pipe. Most guys with turbo bikes like to do sprints. Those who actually have one know what I mean..

[Mr Bogus]

aww you might want to read the post before you get in a hissy... I said "beat on it a lot"

superchargers are less efficient than turbos (some a lot more than others) pony for pony, the turbo has to work a lot less...

Super chargers do not require any warm up or cool down and produce power quicker..
The turbo needs a few to warm up, cool down and makes less power "initially"

after they spool a bit? the turbo will blow the supercharger away..

We did a lot of dyno work on VW/V8 and Diesel motors in Phx in the heat.. Supercharging although hit a lot harder on the line, tend to run somewhat warmer at cruising speeds..

Roots blowers are terrible.. the new breed of centerfugals are much better but still lag behind a true turbo charger..

regardless if you beat on the thing, heat is always a problem..

Talk to anyone that has had to build and stand behind their "hot rods" in the phx heat... not an easy task in mid August...

anyway, there is lots of info on this type of debate out there.. (Turbo vs Supercharger)...

if you are going to beat the bike as implied above by GPW.. you may need to look at a few things for reliable operation....


Have you been out to Firebird yet? (be a good chance to get some baseline "pre mod" runs this time of year... hate to see you spend a ton of $$ and only get a tenth out of her

I am a big guy and love to some sprints from time to time. I have friends that are a lot smaller then me and they ride 1000's. When we are on are little sprints they can pull away from me. Can I get 250-300 whp from the RCC kit? Do they offer an intercooler opition?

Check out their website. Maybe give them a call.

and yes you can and yes they do... I watched Ape Man from here on the board go on Ryan Schnitz's dyno and crank out 250rwhp through a jack drive... (at about 6.5psi).. he has since put the "big" spring in the unit and turned 300hp out of the same system at under 11psi..

kind of sketchy how long a motor in Phx will last at this HP level in the heat of summer with or without an intercooler..

o-ring the head, stronger studs, better valve train, rods, pistons, intercooler and possibly more cooling capacity?

my bet? RCC has the answers to those too..

you would be one of only a very very very few who oring a busa head
not very many if but one or 2 even oring the head of a busa
it doesnt turn out like it does on a car motor

that would be why the question mark after the list... just stuff to look into.. you could probably add a nice list to that one too...

our boost levels for racing were pushing 4 bar... amazing amount of damage you can do to a motor

Hey do you have any first hand knowledge on the "ProCharger" systems? Since Fat Andy got into the gear driven systems, things have come a long way..

[OZBooster]

o ring and copper gasket work well but you have to get i setup right with receiver groove

[BIG GUY]

I might just have to move to a cooler climate during the summer. This is a lot of info to take in. I will definetly keep checking in with you guys and let you know what I decide to do. Do you guys reccomend any shops to do all of the machine work and assembly to the motor?

you tune or read bar?

i havent heard anything about bar since i bought my last watch

If you get a good quality kit they are pretty much as streetable as the next. My bike made over 600HP and I only street ride it. I will admit that its suffered from some vapor lock issues and I have a couple of kinks to work out but that can happen with any bike. I do have around 1500 street miles on it. As much as you weigh I would go for as much HP as I can but personally thats just me. Maybe your riding style is different. I weigh 270 suited and i'm making around 349HP on 14lb on pump with the ability to run up to 18lb so thats probably in the 385-390 range. I plan to tune my bike on E85 so I can run some more boost with pump fuel. An intercooler would def help you out. With the heat your in I'm not sure whats better a/a or a/w. I suggest you call richard at RCC turbos and see what he recommends. I can assure you its not the first turbo he will have setup for Arizona

[GPW]

Destin , you got to bring that 600 HP out to the mile in the spring and let it rip and feel what you paid for legally.

Yeah that would be great. Ive got alot of other priorities to take care of first. I also need to get this fueling gremlin fixed before I try anything like that. LSR is very appealing to me because I like the rush of top interstate runs. What makes me nervous is the tuning of the bikes and how many people blow stuff up LSR. I just don't understand and haven't been involved in the tuning aspects of the sport. I know its alot more involved than have a great dyno tune and dump C16 in the bike

[kawiboy11]

I never had any major problems with the heat while I was in Phoenix, just don't get caught in a 4:30 pm traffic jam on the 51! I had it happen a few times, just had to pull off till it started moving! Turbo bikes & 120 degree asphalt, don't work well together!

RCC's best kit is their Ultra, which uses a water to air intercooler under the gas tank. It uses a separate 1/2 radiator and an electric pump to circulate antifreeze in a dedicated, closed-loop system. It works great, really knocks down the intake temps . . . I am able to make 400 HP on PUMP gas at 20# boost with this kit with no timing pulled . . .

Definately give Richard a call
