I have a 2002 Honda VFR800. Now for the turbo? >:)

Okay guys...

So first off, I've been in the game a little while... I don't need the "I'd buy another bike" or "Why would you do this" crap. I'm cool with you not liking the idea, I'd just rather you save us both some time.

SO- I know they make a supercharger kit for the bike. It's kickass.... However, I have like 750-850 in my bike all together, and that including the cost of the paint I just sprayed on it ... So 5k for a supercharger makes me LOL, I'd spend 5k on a procharger for my 99 corvette long before even considering that.

Okay, so I've been looking at space confinements on the bike, I'm thinking of doing something that people do with the cars I enjoy owning / working on... IE corvettes, camaros, trailblazer SS etc. I think I've got enough room to rear mount / mount under the bike a small turbo.

I'm not looking for more HP than the supercharger kit. I can ceramic coat / turbo blanket the turbo to keep the heat from ever being a factor, There are plenty of ways around the only negative effects of a turbo. I could also mount an intercooler under the bike (yes, it'd be small) but again, I'm not looking to do more than maybe 165-175whp. That'd be PLENTY. I wish that I could just port the heads / full bolt ons, but sadly no one makes stuff for these bikes that :/.

I saw the youtube video where some guy put a turbo up front, but I have no idea why someone would do that, crap loads of heat with it being an inch off of the engine and taking up space for airflow to the radiators. I believe my idea would keep the bike unphased by the addition.

I'm also considering taking an angle grinder do this pig. There's a LOT of weight in this thing... did they make the frame out of depleted uranium?!. thinking of a custom seat, removing a LOT of the tail section, I'd really like to think a turbo, slight streetfightered VFR800 would be a good edition to our group


*Some of my questions involve, how did the supercharger guy get around the map sensor? apparently it freaks out when it sees boost, That's no good. I was under the assumption that the PC3 could tune for boost..

*Has anyone ever got rid of the ABS / linked brakes easily?

*I'm going to check here in a sec, but is there any way to stretch these bikes.. maybe someone saw something fabbed up is why I asked.

I'd love any input / suggestions!!

 

Hope your a really good fabber or have tons o money to burn. Remember, the vfr was not meant to have 175 up, so it's one thing to slap a turbo on, its another to have it survive for any length of time before something inevitably breaks.

The head and fasteners, seals, transmission and clutch, and swingarm weren't meant to accommodate that power. I met a guy once who had the supercharger kit on his 6th gen, and it was having serious problems, but he didn't let us know what, but he never got into Vtec with it for fear of destroying it.

Your probably in no man's land with this, as im sure very few people know exactly what you'll need. As much as it sucks to hear it, there are better bikes for going that fast and for the amount of time and work you'll it into the vfr, you could get rc51, ducati, or aprilia.

 

Damn... I figured that the engines were strong enough soley due to the fact that most bike engines are way over built/ there was already a supercharger on the market for the bike. I could understand it dimishing longevity, but I assumed it to be just about like anything else... LS1s made 325hp... I've seen them hold 600crank for years with out issue. Yes, other parts failed...


BUT- everything I read on these bikes was that they had strong gear boxes, the swing arms are heavy as hell, so I assumed that it was built well. All of the fab work is honestly easier than one would think, the hardest part for me would be the air box, but considering that the filter would be moved down to the turbo, I was just going to build a tubular manifold, or make a fiberglass version of the stock one that I could modify.

 

Here is what you want to use to tune your sixth gen.

As far as dropping weight, I have my ready to ride weight with one gallon in the tank of 460 pounds. There is a lot of weight to drop!
The best way to delink the brakes and drop the abs is with a front end swap. I am running a 2005 Yamaha R1 front end right now, but a resprung/revalved f4i front end would be much much simpler and net 90% of the performance that you're going after.

 

How long will your gearbox and clutch take the punishment ?? Clearly, you bought the wrong bike for you. Check your high-T attitude at the door, willya ?

 

I mean, the engine is built tough, with a lower compression ratio than a lot of bikes, but it's still a crapshoot. A&A performance had a hard time gettin the clutch to not slip, among other things I'm sure.

I have see this a lot, with cars especially, where guys throw on FI without much supporting mods and they almost always have problems.

I'm no expert on the vfr boosting, maybe you should email A&A performance and see what obstacles they had to overcome with boosting.

 

Awww this thread isn't going any where?

 

Right out the wastegate?
