I have a 23 hp go devil SD. Two guys and a dog I can get up to 20 mph Im wondering if a few mods will get me going a bit faster and what should I do without braking the bank and motor?

Heads and exhaust. Add a cam if you have any coins leftover.

What is a good company to use for this application and how much more power do you think I will add.

Usually modding the motor, you are gonna gain the ability to carry a load similar to the same speed you were running empty before. In your case, you will probably be able to step up a prop size or so, which can help in many areas. How much you gain is gonna depend on how much you want to spend. If it were me, and I had it to do over again. Heads decked .045, port and polish, and some valve work (maybe spring for the ss valves), exhaust, and advance timing. If you were wanting to go furthur, I would look into adding a cam before adding a carb. Jus my .02. Do some searching on here. There is several modded 23's.

I know EVT has everything you need to get right. Don't know what all bps offers for the small block...

Thanks a bunch

Sorry for the dumb question, does EVT have a website? I do a lot of reading on the board and see several guys running EVT products. Just picked up my first mud motor and ready to start having some fun with it!

Thanks! I live right down the road from ya in Sachse. Give me a shout sometime and we can go have some fun in mud

Will do.
