I saw in another area where some of you guys were using fuel injection on your banshees. Could you guys give a little more info on your setups and how they are working out? I think it would make the nitrous applications a lot easier to tune. But then again what do I know.

Thanks guys.

Well, you guys let me know at least whether it is worth the money. Good luck with the testing. Get all the bugs out.

At this time it is somewhat complicated. It is only for advanced tuners. The challenge in a nut shell is this: any setup change requires fuel map adjustments. And an error in the fuel mad will cost you your engine. Once a setup is dialed, it is pretty stable, and it could be used by the average duner.

actually the testing has been done for over 10 years ! I've ran this stuff since the early 90's!

but Nates right its not just a bolt on and go thing you really need a load cell dyno and some fuel mapping experience or a big sand pile and a lot of time....

Its only complicated when you have 3 huge cyliders 3 huge pipes and huge turbo and nitrous on top of that
haha

I about got my duner banshee setup complete and Kevin and I did a trx450r that runs on e85 now. In the right hands it is awesone but at this point it isnt user friendly enough to just bolt in on and go. We will get there!

Thanks guys, that is what I was looking for. I am about 45 minutes from my local atv dyno. I think I will stick to blowing engines the traditional way.
At least for the time being.

One things for sure you can blow an engine quick on efi LOL or if you get it right, almost never. I used use it on our 250 micro sprints we once got 2500 laps out of a piston we changed it in fear of fatigue


Some of the systems are low cost because they are old school stuff ...it still works well but the old laptops are getting harder to find..
I also use KMS and Motec system too.

just need to get away from that old stuff and get into modern injection i think a cougar direct injection into the HEAD with the correct sensors would be bad [censored].
the outboards from evinrude are using this tech and its sweet!

some vehicles are starting to pop out with it also

and then add adjustable camshafts hehee

only thing i feel a raptor's injection needs is a mass airflow sensor, knock sensor and a wideband o2. it should be able to remap itself according to what those can tell the comp.

havent heard about them but.. i wonder if the snomo's are twins? that system could be adapted to a banshee or triple or 4 cougar?

jetting changes on the fly more effecient, ability to change map/ timing with NOS whoo ho!

if they need to emmison pass a 2 stroke DI is the way to go some of the outboards are passing the 4 strokes as far as emmisions go.

my first car ( vw scrocco) had mechanical injection on it worked pretty good but as soon as there was ANY vacume leak it went to do do.
