--------------------------------------------------------------------------------

running a 71x96 motor with stock rods and arp bolts(rods and case)a web 86c on type1 stly lifters(48grm)10.5/1 crwelded and ported 44x38 heads with double springs and titanium retianers,pistoins are j&e carbs are 48idf's with 40mm chokes,home built matched lenght header,3 stage dry sump pump,porsche cooling.
think it's making about 165bhp(flywheel)@ about 6800rpm,can feel it go off after this.makes power from 3800rpm.
can i get any more? think i'm at about the limt for this engine,dont want to go any bigger becuase i will go up a class and unless i can get over 300 bhp not worth doing.
this engine is in a 1303 hill climb car ,about 750kg,and on slicks.full race car.engine has had a few years devolpment into it and is very reliable.
cheers rob

yes you can get more, in france f.L from car concept managed to pull out 184hp out of a 71x94 ( 1971cc ) and E.D from remmele got out 200hp out of a 1971cc.

hightest range power was between 4500/7800rpm. these engines were affected to racetrack vw, in the french vw cup challenge and the divinol cup challenge.
