Re: Anybody here have their Q-jet mounted backwards?
Thanks Evan. I run 4+ trails now, and it seems these days I'm getting more and more extreme with what I do with my K5. I'm finding more and more limitations with a stock set-up and I'm modifying accordingly. I'll explain further for those that think I'm 'smoking something' [img]images/graemlins/smirk.gif[/img]
Try this and tell me what you find [img]images/graemlins/wink.gif[/img]....... Drive forward up a hill that gets steeper and steeper, almost to vertical. Keep in the throttle (moderately) until the motor starts to die. Let off the gas. Does it still idle? Make a note of the max angle achieved. Now do the same thing in reverse up the hill [img]images/graemlins/cool.gif[/img]. There's many a hill that can be taken in reverse, but not in forward.
Here's what I've found on my rig through testing, research, and on the trail- Q-jet wise. Keep in mind my crawl ratio isn't very high, yet [img]images/graemlins/wink.gif[/img] (the doubler is gonna happen soon), I have to keep in the gas, power braking, etc. torturing my tranny [img]images/graemlins/tongue.gif[/img].
1. Forward uphill is limited to 35-50 degrees while in the throttle
2. It will idle up to around 60 degrees
3. Backwards uphill will get to about 65 degrees, and still be able to step on the skinny pedal without the motor sputtering and dying on you.
4. The cavity in the front of the bowl is filled with a spacer, keeping the fuel level somewhat in a decent area for downward angles
5. There is no spacer in the rear of the bowl, so on uphill angles, the fuel either dumps into the secondaries through the vents, or uncovers the primary jets.
This is a mod that's been done. I was asking if anyone on this board had actually done it, because I am checking out the differences in cost vs. effectiveness from going TBI or the Q-jet backwards. Yes, TBI (or TPI for that matter) will run upside down, but I'm thinking that running an engine upside down is a bad idea [img]images/graemlins/crazy.gif[/img].
