Title: Twin carb firestreak manifold Post by: grey58fc on December 11, 2009, 10:18:09 AM can any one tell me why on the manifold i have got for the 138 in my fc, has two bakelite (or similar material??) spacers between the manifold and carbs, a bloke who did one up in the seventies said it was an "ole hot rodders trick" to get more torque or something? being 16 i dont really understand what went on in the seventies... but is this a valid statement and should i get another two spacers made, the ones i had crumbled when i toook them off.
any help would be appreciated! Title: Re: Twin carb firestreak manifold Post by: Ed on December 11, 2009, 11:08:45 AM The theory is they stop transfer of heat to the carb and fuel bowl. also create a longer intake runner length which results in increased intake velocity.
so cooler intake charge and increased intake charge velocity = better chamber filling = more power. sound good? Cheers Ed Title: Re: Twin carb firestreak manifold Post by: grey58fc on December 12, 2009, 04:10:03 PM sound prettty good, hahahaha thanks
