Keeping my fingers crossed that a power commander will be out shortly. However, does anyone have any idea as to how much power the new efi unit will be able to back up? Will it be able to support the big bore motors, hi comp, cams, ect? Or will we end up yanking the efi unit in favor of a carb? It would be a shame to have all this technology to go to waste, and get bested by a $200 big bore Keihin.

 

I dont know exactly how it will work but i do no it is made for supporting new cams, pistons, and all all other major mods. There is a little prob tho when u do a mod such as those you will have to get hook it up to a comp so it can draft it into the efi so you will get the optomon performace. As for an exaust, K&N, headers, ect those the efi will automaticly draft in. Hope if this helps as for how much hp it can support is limitless to the mods you put on, As for the power comander I for one have asked and no one i asked and how many sites i looked up never mentioned anything about this. Im pretty sure there not going to be like suzki with there king quad with this. But if they made one which i sure hope they do that would be great.

 

do you have one? how does it compair to the 660? im very interested in one, i just picked up the august dirtwheels and im reading up on it

 

12-1300HP




J/K The system would not be limitless. The stock injectors will have a limit to the amount of fuel they can provide. That will be the limiting factor. Up the injector and you can keep going.

There are MANY types of fuel injection. More than likely it will be like sportbikes are that require a TPS/RPM map. This type will not be as easy to mod.

 

I think the airflow from the single carb setup will be the limiting factor. One carb can't flow as much as two. I think they should have went with a dual fuel injected carb setup.

 

the sky is the limit basically...once u get so high ull have get a bigger fuel injector, im not sure how big u can go though.....

 

i think before its over everyone will find out it will cost more to modd the fuel injection,ie power comander,bigger injector,ect.than it is to add a set of carbs to the 660,depending on how much motor work you do
plus if it has a o2 sensor you will be limited to the type of fuels you run

 

and u dont think motor heads will figure out how to bypass/make aftermarket stuff for that purpose?

 

I understand how and EFI setup works, Im asking is anyone knows the size of the injection unit used? Would it be comparable to lets say a 19 lb per hr injector in a car? If anyone knows the flow rate of the unit, the ammount of HP it can support can be figured very eaisly.

Take the number of cyliders and mutiply it by the flow rate of the injector

example ill use a 5.0 mustang with 19lb hr injectors

(8x19x.8)x2=243.2hp--------The stock 19lb injectors in a 5.0 mustang are capable of supporting about 244hp


Lets just assume that the stock raptors injection unit is capable of flowing 19lb an hour (this is way to small)

(1x19x.8)x2=30.4hp

Im guessing something comparable to a 32-36lb injector would be used for the Raptor, this would support the HP that most of us are figuring the new Raptor to be at

1x32x.8=51.2hp---------this figure may be a little on the high side, but you see where im going.

However, the injection unit could be comparable to a throttle body injection. Same forumla applies, however I think thier flow rates are measured different than TPI style injectors.

 

I would dare to bet when a PC is made available it will be able to solve fueling problems for just about any mod U can throw on the new Raptor. Ive been into the Yammi sportbikes (R6/R1) for several years and the powercommander could always support, slipons, full exhaust, race filters, velocity stacks, porting, bigbores, in almost any configuration.
