Nitrous?

[Brembo]

Tripp, I also injoy the thrust of a turbo kit. I have an IHI turbo @11 psi, 267 rwhp & 267 peak torque. I'm about to install a dynojet mult-port and do some "more" fine tuning. The last tuner could never get the two bar map sensor to work. Right now it's disconnected, the bike runs fine without, but the check engine lights on. Also, on a nother note, I have to crack the throttle to get her started when shes hot. Hombre knows about most of this and he's exactly right about 2nd & 3rd gear...nothing but rubber. I used to like that when I was younger, now I want to get off the line. I don't want to go as hard core as a slick, I'm a street rider. I'll see what happens at the strip, She might get off okay. It feels like the front wheel is 6" off the ground through 4th. Practice on street asphlat is not a good judge.

so anyway like I was saying...Nitrous... But I guess if I have to spend several thousand to get a wet kit and nozzles all workign then I might as well save and get a blower or turbo.... since all these people had to chime in and tell me about there wonderul turbos and such... I was hoping somebody had already sorted out a decent wet kit already and would share there secret..

just want it for the track.. I actually make plenty enough power for the street

Regulator, I think you need to figure out whether or not you would gain more by replacing the stock plenum and going with an under the tank K&N and NOS or sticking with triple K&Ns.

 

[REGULATOR]

yeah, I wasn't too concerned with replacing all of that when I removed it...

Id like to get ahold of the tubing that comes with the SC

tripp & hombre,
i guess what i'm looking for is a graduated system that would let me acclimate as my skills improve. i want the juice of the turbo,just not all at once. does that make any sense? the super charger set- up that hombre has is drop dead gorgeous. alas, i'm not suited to that sort of in your face alacrity. a ride like that would surely cause me a lot of trouble..... my thoughts also lean towards reliability. what with the trips i've begun to schedule,i can't encompass any breakdowns near term. and tripp, don't sweat the long post. i thoroughly enjoyed reading it. just wish you could go into more detail. hombre,your words bring much clarity and wisdom to what i am contemplating. i never take what you say without serious thought. thanks to both of you.

Thats ok ,dont worry......

Turbo is bolt-on kit wiht Garrett and PC.....easy set instal and drive

Goodfellow,
I have NO experience with a forced inducted R3. But I do have experience with turbo'd 'Busas and 'Herdleys', and I wouldn't recommend this for 99% of the good riders I know. At 100mph, more than 50% throttle and you are looking at sky... very temperamental, and not fun in the twisties.

It is hard to beat forced induction for hp/Dollar spent, but this may not be what you really want in the end. With an easy 6-6.5% more hp per pound of boost, many wind up with more power than they really like to ride, and wind up short-shifting before boost comes on - but the power is available if and when you need it. The low compression and low cam timing R3 lends itself well to forced induction. The big thing is that the cost of the supercharger kit does not include the time (and money) spent tuning the system after it is installed, this is not a small project - ask Hombre.

Personally, I really like the idea of a centrifugal supercharger, like the Rotrex, on the R3. Air flow comes on as the revs climb, and makes this a controlled rush to the redline with mild manners at lower rpm. Compared to N2O or many turbo kits that come on abruptly, the riding manners for a centrifugal should be very good.

I feel that Vortech has a unit that may be really good for the R3's flow needs as well - it is just that no one has developed the mounts and drive needed - a fairly good job, but not too hard. This could be a good bit cheaper than the Rotrex kits if done right. It could be very compact if done with a water-air intercooler (mounted at the throttle bodies) like the very efficient Laminova cores. I have a box of these cores gathering dust in my garage.... Hmmmm. Or it could use E85 without an intercooler, but this may not be good for long road trips where E85 is scarce.

What a forced induction R3 likely will want (others like Hombre can add input here) is slightly taller gearing - especially at cruise speeds. The shaft driven differential on the R3 will make this an expensive proposition with custom gear(s) needed.

It all depends on what you want in the end.

I have a good collection of superchargers that range through multiple Roots designs, centrifugals, Lysholm screws, turbos of various sizes and AR ratios (YES, Turbos are still superchargers), and even a Latham axial-flow. But most of this is for cages. Bikes are different beasties, and need to be treated (and modified) for the desires of the rider - most don't really know what they want, they only think that they do.

IMHO, the R3 has more than enough displacement to make the torque required to terrorize the streets. The problem is that it is severely de-tuned and is NOT efficient - it doesn't make good torque/liter numbers. I think this can be easily solved - at less than the cost of a supercharger set-up.

Consider what you really want the bike to do, and how you actually spend most of your time riding it. Then balance this with what you can spend without getting carried away or buyer's remorse (important). You may think you want a really high dyno number, when all you really want is enough performance to take on most of the local guys and still ride like you have been riding. There will always be someone faster.... always... ask John Force (who, by the way, is now relocating to NC).

Sorry about the book length post. -WT

well,
i'm thinking this is going to get very interesting in the near future.....

Greg,
From what you're saying, I think the turbo would be right up your alley. Like the Rocket is now, it's only going to give as much power as your right wrist gives it.. Turbos, in general, are also very reliable. I have 135,000 miles on my 7.3 liter turbo diesel.. I would also expect you to retain close to your current MPG at cruising speeds. Of course, when your right wrist gets heavy, your MPG will go down quick.. but what a rush!

One of these days...for me that is. Although, I like the supercharger route.

Dave,
i'm just having a hard time deciding on which way to go. i'm really leaning toward the turbo. i've got one in ronis' subaru. it's dead reliable.... any way,i need to get back to installing the flip bling since i got my front and back tires off. later bye........

To my mind everybody know best way to build his own bike
This argument subject is fun to all

off topic: I leave to forum,and i go to drive this week.... Start to Sunday and back to next Sunday....Tour is 5000km/3100mil to one week....Rovaniemi (Arctic Circle)-(Belarus)Minsk-Prague(Tseck)-Travemunde(Germany)-Helsinki(Finland)-Rovaniemi(Arctic Circle)

See you everybody after that,and then go on debant....i´ll be back...
