twin tower power

[smokeonthewater]

there is pretty much nothing you can do cheaply to up the power on these... in fact you actually have to detune em a little if you want em to last... they were built for way better gas than we have today so factory spec timing is a little too aggressive for today's fuel.

they are still fine engines but you can't just swap a few parts to make more power..... ALSO parts are NOT easy to come by and many parts just aren't available for em anymore.

will one push a v20 lightly loaded?

that's what I have on mine.... haven't tested top speed yet but jumps on plane almost instantly

Remember these are rated at the powerhead, in 1985 the hp ratings were at the prop, about a 15% hp difference.

The towers of power came out in 90-115-125-135-140-150. They are great motors and not bad on fuel either. Making a lower hp model a higher hp model is tough, differences in carbs, intake, porting and exhaust. These can be found fairly easily, I know 2 guys that have about 20 top's around there shops.

They run crazy good, mass quantities of torque out of the hole!!!

A single 140 or 150 would work good on a V -20. But a pair of 150's would be crazy SWEET!!!
