I think the new hood will be great with the turbo, just make the intercooler visable.
the real question is how easy did yamaha make it to reprogram the FI

I never said I was all there to start with.
Hey! save a few of those oxycontin's for sled'n next year.

Anyone know if we would be able to change a chip in the putor like in cars now with fuel injection to increase HP?

So, back on topic here.Whats involved in running a turbo with fuel injection? Bigger fuel injectors? I see mc-xpress has some sort of plug in module into existing fi system for r1 ,what does this do? I assume it gives more gas when boost applied but how do they work?

To build the turbo properly a 5th injector must be installed in the plenum and the you'll have to make a program for the fuel injection, If not adding to much fuel to the existing injectors will cause it to dribble at low rpm's. It also must a selector switch that cordinates with all levels of boost, or you will have to have a computor and upload when you change boost levels, A small pocket computor would be ok. but either a selector program switch or computor the price will $500- $1000 more for sure. The intercooler is no big deal to refit, but for the front mount turbo I believe they will have to cut a hole in the hood pod and put a cooling dome of sorts to release the temps and its going to be real tight. I hope they fit it!!! (you won't be able to lift the hood in the area of the current turbo.) The rear mount kits will be simple to convert. This sounds simple but you must spend hrs on the dyno analyzing the data and compensating for hp by adding fuel. The censors on the injection system will make doing this easier. When done properly the result will be a better system all around.

Anyone remeber when the buick turbo V6's Switched from carbeurators
To fuel injection and Hence the "Grand National " was born ...............................

The FI will have one BIG advantage over the carbs when it comes to turbos.
you can get rid of the existing throttlebodies (or just remove the butterflys to disable them, and put on bid thottlebody with a relocated TPS in front of the turbo.
that way pressure wont spike and the turbo will stay spooled up when you close the throttle, like a Lighting Pro turbo but with a more conventional turbo layout.

Moose- you can't run a spercharger without an intercooler- the supercharger runs all the time, and the intercooler gets very hot. Luckily the Apex airbox is designed to be replaced by an intercooler ! (smart design)

Alot of this depends on how "tunable" the factory fuel system is. If it is easy to tune on its own or if we need to use a piggyback fuel controller. As long as either one of these options works this turbo thing will be easy. Worst case is you buy a set of big injectors, FPR and a piggyback to control the injectors...that will give you all the fuel you need for whatever boost the engine will handle. I don't see the IC being a big deal, other then trying to retro fit the RX one on to the new sled. These guys are good. They'll build something that fits.
