Slanted or angled engine?

[drossman]

Can someone explain why guys slant their engines? Is there a benefit or is it just because it looks cool?

Hey Dman not sure why some of the old style frames slanted the engines most likley due to better fit I had to slant my engines on my build off bike just to save space.

Cool thanks. I think I'm going to do that on my next one.

Guys didn't slant their engines. The companies slanted the frames. Rupp, Fox, Speedway, and a few others started slanting their 10" wheeled bikes around 1970. Before that, most of the bikes from the 60's all had flat engine plates. It was done for looks. I guess they figured it would look a little cooler with the engine leaning forward than sitting flat.

has more power leaning forward in the direction its going. Plus better cooling with the head in the wind . And the slant helps the gas flow in compensating for the forward motion. All very large improvements :thumbsup:

I may be dumb but, I sure don't understand that logic. How does slanting a engine in any way shap or form improve performance?

 

[jeep2003]

Just kidding buckeye :laugh: It does nothing for performance

 

[buckeye]

Damn it. I was wondering.

I think you missed the sarcasm buckeye :laugh:

 

[buckeye]

Slid right over my bald head.

Usually it was done for adding a jackshaft behind the engine and conserving space.
Also it was to imitate Motorcycle engines.
I hate slanted engine plates personally, but that is what we are dealt.

while the rest of his answer was pure sarcasm tilting the head into the wind might have been a feasible concept for cooling. it sounds possible but i doubt if anyone ever measured the difference.

There are a lot of racing karts with Raptors that are slanted, so is it for looks or some sort of advantage than sitting level? IDK, I just notice it.

Its no secret slanting a flat head engine helps flow to the piston.Yes they run better that way.

 

[buckeye]

Not falling for it this time!

 

[drossman]

Lol buckeye. I honestly thought it has something to do with pulling the chain and engine stress.

 

[buckeye]

Sure ya don't get more torque??? Better fuel effeciency?? More rpm's. Oh, I know, the clutch engages at the exact correct time.
Wow, I need to slant a engine.
Really...

The slant engine will clear narrow frames period that's all folks. No added power performance actually sacrifices power and efficiency.

rupp slanted the engine cuz it looks cool and takes up less space in the frame as far as height
.
karts slant the engine to get the air filter and or carb away from the tire
.
if anything slanting the engine is not such a great thing because the fuel in the bowl is not level with the carb & and the splash oiling system is altered a little
.
it seems to work ok so dont worry about it :thumbsup:

I remember seeing a car that was all jacked up in the rear in the 60's and I asked my dad why and he told me that it made it faster because it's always going down hill :smile:
