    F7R bottom end max revs

    ok wats the max rpm an F7R bottom end can take? ive seen a few williams lumps sat at well past 7k revs with a chipped ecu. i know the megane block castings are different, but are the rods, crank pistons more upto the job of higher revs? cheers jimbo

    Yozza’s Blown Engine update

    oh right, thought they wer bigger than that. so does the f4 head breath better than say a megane head in standard trim, or is it the cammage that provides the extra power? jimbo

    1.8 16v Head Gasket Questions

    he mite as well do it himself, only take a day to do, and cost a max of 100quid with new belt and tnsioners, and gaskets,etc. dont go n give these companies ur hard earned cash, when a bit of elbow grease can have it done for not a lot of cash. jimbo

    2.0 litre conversions

    rsi head on 2litre laguna block will be rapid. torque monster. with a bit of work, 130-140lb/ft would be easy to obtain. jimbo

    Handling - Willy Vs 16v

    the williams uses a different steering rack than the 16v. most likely longer track rods. u could jsut wind out the current track rods ends on the shaft out the extra mm for the proper track. the 19 16v, williams, clio 16v hubs r the same, so itl require new wishbones, driveshafts, and...

    181bhp cup

    i gota say, i think 160-165lb/ft is possible at high-ish rpm, but 190lb/ft on stock plenum injection seems alot to me for a 2litre. i think il have to have some 172 magic dust sprinkled on my engine lol jimbo

    181bhp cup

    but civic type rs dont make 190lb/ft tho do they, 150 at best. but its made high in the rev range, therefore a nice bhp figure. so in all honesty, roamer mite as well have jsut fitted flowed head n cams rather than tbs in order to get over 200bhp? jimbo

    181bhp cup

    the vauxhall c20xe cosworth designed 2litre twin cam has been used in motorsport of all forms fr past 15 odd years. its been tuned to the max(you will probably know the score ben r) and is known to be one hell of an engine. standard form uses a 65mm throttle butterfly, and smaller 20mm primary...

    181bhp cup

    im talking about the whole inlet system. the single throttle body system simply cannot flow the air to allow 190lb/ft. stick the engine on a proper engine dynamometer and il beleive ya. 190lb/ft is touring car engine torque output, and they need 8500rpm, mad cams and big throttle bodies to...

    181bhp cup

    if thats making 190lb/ft of torque il eat my own ass! surely the standard fuel injection system cannot flow enuff air to produce 190lb/ft. youd need throttle bodies to get that kinda torque figure, even that wud be pushing it. jimbo
