What's the comparison between a 2.4 BP (225 hp) and a 225 PM?
Roy, a dsra legal superstock 2.4 200 will turn an average between 8300-8800 depending on setup. I've only played with efi bp,s but I found it to come on alot stronger at 6k and above compared to a 2.4 200. I think the bp would make hp higher in the rpm than the 200. I've got a bp I've been thinking of rigging as an until it blows warrior..... Gonna have to see what she,ll spin with a 660 setup. I think on squeeze the bp will make 9500-10kA good bp will turn 8000-8500.

SUPPOSEDLY..... the efi was rated at 240 and carb at 225. there were rumors that mercury underated the carb to help justify the price differance for the efi. i beleive john marles said he dynoed the stock carb engines at 240. i had a mercury engineer tell me many years ago that the efi bridgeport was closer to 260hp. who knows ??? the later bridgeports ,did have top pinned mahle pistons that were relieved in the bridge area and had a black coating on them.. i purchased some new replacement pistons that were like this.. some guys were drilling tiny holes there, or machining a flat spot on the pistons where the bridge is to combat the heat in that area ... i had a warmed up bridgeport back in the early 90'S that seemed to run as good or better than most 2.5s that were coming out about then. its been along time ago..but from memory ,my 2.4 seemed to perform a good bit better than my 225 promax i had on there.I was referring to stock vs stock. By stock, I meant out of the crate. Btw, the 225 bp was a carb. I recently bought back, for the third time, a bp carb. The last time I owned it was about 10 years ago. Anyway, differences I see: Bp-five petal front, quicker? 16 amp system w/ steel flywheel-quicker..(efi version had alum flyuwheel) PM 7 petal, behind the liner, 40 amp w/ humungous flywheel, steel sleeve, rev limit (ok, don't count the rev limit or oiler). IMO, don't turn a stock pm over 7k (rod bolts,bearing cages)
reliability? Didn't the 'bridge' on a bp have issues from heat?
wow, you must be old! LOL :at the barI bought my original 225 bp for $6700 in the crate. Add a new stv for 6200 and had a turnkey 100 mph boat for less than 13--all new. Those days are gone...
