914/6 vs. 914/4 AX Performance, Heated Disscussion Within Options

[Britain Smith]

I know this guy...he is looking to purchase a 914...wants to be really fast on the AX course...and can't decide between an original 6 (or conversion) w/ 2.7L (or some sort of uprated motor) or a Raby (or similar) four cylinder.

Putting the discussion on equal playing grounds, lets say that both chassis are identical, which would be faster on the AX course? This is assuming a well built chassis, with a cage, upgraded suspension, hoosiers (or similar) tires, etc.

For AX purposes, my vote would go for the 4-cylinder car all the way. I have my reasons, but I want to hear yours first...so which is it?

Another thought on power to weight ratio: If the car weighs 2,200 with a four and 2,300 with a six then the six only needs 11 hp more than the four to maintain the same power to weight ratio. Jake's 2563cc motor makes 200hp*. A warmed-over 2.7 makes 225hp - or 14 hp more than needed to maintain the same power to weight ratio.

That argument only works in drag racing. Doesn't apply to autocross in any way, shape or form. I beat cars with more than double my power/weight ratio all the time.
