I will go over my notes from when we had mine flow tested. If they are the same part as the Prowler 1000 I might be able to help you but I don't know if they are. The Prowler 1000 injectors were maxed out when we dyno'd my XTZ. I ended up going with a much larger injector. I went larger then what i needed so we could run E85. I will look over my notes and see what I can find.Does anyone know what size the stock injectors are in the Wildcat?
That does seem small. We did boost the fuel pressure with the stock injector to 60psi and it put us at 100% duty cycle and that when we switched the injectors out. We dyno'd over a year ago so this is all from memory. I will check with the dyno guy on Monday to get some better info.22 lb/hr is 230cc. This puts the HP at 70. A bit undersized in my book if this is what's in the Wildcat.
Here's your HP value's ......That does seem small. We did boost the fuel pressure with the stock injector to 60psi and it put us at 100% duty cycle and that when we switched the injectors out.

I plugged in some other variables to compute ........Shoot I forget the compression but I think it's 10.5 to 1 and we ran 12 psi.
Your calculations after being adjusted are not far off. This was one of the runs we made before the rear cv cage decided to exit the building!I plugged in some other variables to compute ........
Static compression of 10.5:1
12 PSI Boost
Equates to appx. 140 HP at the crank.
Be curious to see what you actually Dyno'd -- And I like that Duno by the way .. .. Just wish we had one here in Havasu ........... Like to put my Turbo'd RzR Classic on it !!
No need for a larger injector unless you run forced induction. I am sure the factory injectors can flow enough if you stick to the NA motor even with mods. You can always add fuel pressure with an after market pressure regulator but it gets tricky. There is an internal pressure regulator on the fuel pump that you need to fool.Can we put larger injector in with out using a turbo and will it help the power.
That's the beauty of the CVT. It constantly changes the gear ratio. These torque numbers are accurate.Based on my estimated crankshaft HP of 140 and your Dyno run making 118 at the wheels equates to appx. 16% drive train loss.
My thought on the torque value at 3000 Rev's is -- The clutch is not locked and with the gear reduction at that low of an RPM and wheel speed - The torque value is unrealisticly high. Almost looks like the clutch at this RPM is a 3:1 gear reduction. This is just my very uneducated opinion though.
Have you had any engine trouble since you installed the Turbo and have you done any engine work before the Turbo installation ??
And for that matter - What is available for this engine ...... I do see that Speedwerx does offer a big bore kit for it ... .. I've not seen much else.
I know nothing about the Artic Cat V-Twin as to how reliable it is - Or how far it can be pushed.
Swapping injectors is as easy as changing the spark plugs - From a mechanical standpoint. The similiarities end here.Can we put larger injector in with out using a turbo and will it help the power.
