bennieben1 Posted July 29, 2009 Report Share Posted July 29, 2009 just a question. how many horses have you squeezed out of stock jugs, stock carbs, and stock stroke crank. what was your list of mods? i love it when people do alot with very little in any situation in life. i have alot of respect for that. but this time id like to know what kind of power members here have achieved with stock looking cylinders, carburetors, and crank.

dco3100 Posted July 29, 2009 Report Share Posted July 29, 2009 Only obstruction is the 35mm Pwks i had on it, I put down 59.8 horses and 42.0 ft/lbs of torque. Other mods were vf1s, prodesign cool head with 17cc domes, k&n pods, +4 timing, Toomey T5s, and a trail/dune port. :biggrin: Quote Link to comment Share on other sites More sharing options...

They are good dynos and should be labeled with this: Land & Sea didn't take that idea from one of my engineers at a previous employer. :biggrin: Quote Link to comment Share on other sites More sharing options...
FireHead Posted July 30, 2009 Report Share Posted July 30, 2009 The best I did was the following when I was still in skool. *OEM welded crank balanced with entire rotation assembly. *OEM remachined head. *OEM carbs bored out to 30mm and bored for larger slides (not worth the time and effort). *OEM cylinders with sleeves pressed out, casting and sleeves ported, then reassembled (done on a live 4 axis CNC mill). You could consider it a hot dune port by industry standards. *OEM pistons machined to be equal weight. *OEM rods machined to be equal weight. *OOF handmade pipes. *OEM reed cages, ported, with CF reeds (I made the reeds, which wasn't worth the effort). *M100 fuel w Castor 927 oil. *Dyna ignition w/ OEM coil. *The radiator and cooling system in the test cell was used with an electric water pump and thermostat set at 190 degrees. The engine ran for ~10 hours on a Super Flow water brake engine dyno (driven off of the crank). It failed a reused OEM crank bearing at about that time. Peak mean horsepower was 101hp and I can't remember the torque, but I can try and find my engine build book for the engine if anyone cares.

Hulio-mv Posted August 4, 2009 Report Share Posted August 4, 2009 51.55 hp and 31.3 torque with mods in my sig 60 mm stock bore and no real intake port work just casting flaws removed and the transfers smoothed I did take some material out of the exhaust side and polish it. I have played around with a few set of cylinders and a couple of books and cds on 2 stroke port work. no I am not a pro but it is good to know you did it yourself Quote Link to comment Share on other sites More sharing options...
