Lay down engine swap

[sledtrash101]

I have a Polaris axys chassis that I'm building from the ground up, my designated engine will be a m8 arctic cat. This engine has the exhaust and intakes in the same side of the engine. The problem I'm running into is this: by the time I line my clutches up the intake ports end up pretty much behind the steering post. If I throw the throttle bodies on there won't be much room to get my plenum built and attached. My first thought was to machine a block that replaces the reed boots and offsets over to avoid the post. Or install a 90 degree turn down. This machine is fuel injected at the throttle body.


Two questions

1: how much performance will be lost by adding distance to the plenum between the throttle body and the engine?

2: can a throttle body on one of these sleds run in a vertical position or semi vertical

a picture is worth a 1000 words.

just curious as to the reasoning as to why you are doing such a swap

Because I can and a want to. Need I have any other than that?

plan it, do it , tear it down then replan it and rebuild. then see how it runs ,, then tear it down and rebuild it a couple more times till you are content with all aspects ..

and yes because you want to is enough reason

No adverse effect to any angle on the throttle body, there shouldn't be much difference in an angle, but have you ever through about the single throttle body set up for a turbo?

I haven't heard of the single throttlebody I'll see if I can find it.

I have thought about a turbo but then I also would like to "build" my engine to the best extent possible. I love high hp NA sleds.

Ippielb what about offsetting the throttle body over equally via a machined aluminum block. Maybe machining a injector hole ight in front of the reeds?
