Re: Need more horse power
As much as I hate to agree with ANYTHING this cast of scoundrels says...[img]/ubbthreads/images/graemlins/ooo.gif[/img]
They would be correct about engine size.
An engine with a long stroke will give more torque.
An engine that has more cylinders (but shorter stroke) will give more horse power than torque...
In your friend's cases, there are really only two options,
One is to install a supercharger to wring the last few horse power out of the little engine,
The second is to just install a larger engine.
If I were doing the recommendation, I'd suggest a MODERN light weight V-6 engine instead of the antique, over weight Inline 6 cylinder or over weight older iron V-8 engines.
Light weight, fuel injected V-6 engines grow on trees in salvage yards and remanufacture shops.
Engine Mounts and adaptors are usually exactly the same things are their larger V-8 counterparts, so those non-wear parts are available. (Non-Wear means one time purchase)
Anyway, no real gains will be made from this point out with that little 4 cylinder unless you add a turbo or supercharger. You might squeeze out a few more HP with this or that gadget, but you are at the point of diminishing returns.
Meaning larger and larger money for smaller & smaller gains.
Force feeding the engine with a supercharger will make it put out V-8 power, but at the cost of shortened engine life, and the kits aren't really what I'd call 'Cheap'...
