formula 272/292 with mags speed?
 

formula 272 with mags speed? anyone got one, in 1990/91 they made a few with 454/365hp mags vs the stock 454/330 I know they run 60-63-4, what do the mags get it to, real numbers anyone got em?? also whats the 292 run with mags? I have been looking at 303's but seem to keep coming across really really good deals on the 272's, 292's and 311's

i dont have mags but was seeing 67 gps with 454 330 lower ends 781 large oval port heads dual plane intakes, prob 375-400 hp each with 23p mirages, def needed 25s could pull 5100 even with 4 200lb plus guys 130 gallons fuel and 3 full coolers. hope that helps a little if not sorry for taking up space lol

Lil thanks gives me a start, I've heard that the 292 was the same speed as the 272 with same power because the 272 was to tail heavy not sure if its true or not

I have heard that also, but haven't been in a 292 to verify

mag speeds
 

I had an '89 272 with 330's, low 60's, boring,so I upgraded the motors.High rise intake, large oval ports,cam and Imco exhaust.Now would run 70-71,turning 25 Mirage 5000-5100. I still have an '89 311 with 454 mags,stock except for Gils.Same Mirage props as used on the other boat, 4850 rpm about 67 mph.Bravo 1 props ,26 pitch ,4650 rpm ,66 mph.

I have an '89 292 with 454/365 with new cams, inconel valves, 850 Holleys, roller rockers and Revolution exhaust. Puts out about 420hp per. 5100rpms and she'll top out around 72-73 with 25 mirages.

My 292 with 6.2 MPX's, 320 HP a side runs right at 70 on GPS.

anyone have one thats stock??

I had a 1990 292 sr1 with stock 365 mags. did add stainless marine exhaust though. Ran 67 with stock exhaust and right at 70-71 with the stainless marine exhaust, pleanty of fuel and 4 adults. Also added full hydraulic stearing and that improved the handling tremendously. Boat wanted to wander with stock steering. I think I ran 25 mirages right at 5000 to 5100. Loved the boat.

Those are numbers I can live with,

I have 454 mag 385hp gen V's with carb/intake upgrade...probably 400 hp each turning 24p bravo 1 4 blades @5000 rpm. Mirage 25p are a little faster at the same rpm but don't handle as well. Best is 70 mph but more like 68 for a full load of fuel and passengers.

I have a 1991 292sr1 with 502s.Bored out 30,Imco exhaust
,cam, rhs heads,roller rockers,800 holley,msd,merlin intake,msd,imco hydraulic steering,26"bravos trimmed out 78-80.77 all summer long.steers like a corvette....

did u do the work? what did it run stock?

I had a 91 272 with 454 mags and it ran an honest 70-71 all the time in fresh water.

if thats where I end up i think I would be stoked with them numbers

The factory advertises 70 for a 29 FasTech with 350 Mags:evilb:

not looking at newer 292's wish i was but there just a tad outta reach for me

My 89 292 with 330's will run 63 mph with 24 pitch Hydromotive quad IV's @ 4600 RPMs. This winter I'm removing the 525 hp 440 CI engine thats in my 242 and building a clone and putting both in my 292. Hoping for 80 MPH with 1050 hp combined.

242ls....i Did All The Work Except Build The Short Block And Heads.i Have My Machine Shop Do All That.rest Was Mine.i Did Not Know What It Ran Prior.it Is Advertised Around 70 With Mags ,so I Have Read.....
