I know 100 deg is obtainable with other setups i was just posting it because of where I'm getting my water from ( almost engine temp water). With some testing I did with doing one motor directly from the sea strainer and the other thru the crossover it was 18 degrees cooler but was in different operating conditions. I have the fitting to change it over but don't want to change too many things at once. Also another note on iat's i know of many setups that are in excess of 130. And that in a boat is to the point of needing timing pulled.

I'm thinking I'll be able to keep them at 90 deg ish when plumed to cooler water. Another good thing is the intercoolers are pretty cheap. I got both of mine for about half of one roots style intercoolers.

I find it a great shame that you just couldn't get that extra .5mph to hit the century mark on that baby, lol.

That little 232 was a REAL handful, ran mid 80s when we were done, told owner his next purchase should be twin ram full hys steering. Friend who bought the 272 had us put a m-3sc back on it yesterday but its on a iron headed 560hp 502 not the 548 i had. Going out to water tune that today or tommorrow, will probably run 78ish, with the big trim tabs and hyd steeringb i left on boat when i sold it that will be like a gentle cruising speed! |
Bajas have their place in the world, it's not at the century mark. :) Kuddos for trying though! I actually took your experience into consideration in what to do, or not do on my 272.

W 24"trum tabs, nose cone and full twin ram hyd steering boat was fairly solid to mid 90s, you wouldnt run those speeds in 3 footers or bad criss cross wakes by any means. I did race that 35 or 36 ft baja in pt huron that has lingenfelter 604's thru 2-3 foot criss cross waves for 8 or 10 miles a little hairy!!

Not my final version but I made these up real quick to see how big of a difference it would make. Holy crap! Huge difference. So much easier on the boat.

Mike tkach and I were talking about those for procharged setups
