marshole82 0 Posted January 13, 2009 hey all, anyone know what the direct to head kits actually do? aside from replacing the induction system what sort of gains can be had? what does the car sound like? i've looked at the jenvey website but to be honest i don't know what bits i'd need to do a conversion. can anyone shed any light? cheers Quote Share this post Link to post Share on other sites
flusted 0 Posted January 13, 2009 seems alot of outlay for little power? they are guna sound lovely though. Expect gains of about 20bhp? Quote Share this post Link to post Share on other sites
Neil VR6 0 Posted January 13, 2009 You can get good power but you'd be better off by pairing it up with a flowed head, cams and other things to make the most of all the extra air you can suck in. The power is likely to be in the upper reaches of the rev range too (which is OK if that's your bag) Quote Share this post Link to post Share on other sites
marshole82 0 Posted January 14, 2009 to be honest, i'd have them if i was minted. was really just interested in how they work and whether they are worthwhile for the cash outlay. how would they work the metering head on the KR k-jet? would i have to purchase a standalone fuel management system too?

flusted 0 Posted January 14, 2009 they are good because you can map each individual cylinder for air/fuel and still get very good idle with really lairy cams. Yes you have to have management to control the fuelling Quote Share this post Link to post Share on other sites
