soobie_newbie67 Posted June 30, 2013 Share Posted June 30, 2013 (edited) So. Let me reword this a little since i came off kinda harsh. They say (Delta Cams) Custom orders over the phone. My topic got locked so i couldnt ask any further questions there, and i couldnt find the info i was looking for searching (i'm sure its on this website somewhere). Maybe i'm getting ahead of myself here. I should ask WHY do people put in the delta cams in the first place? what changes do the cams make after upping the compression with the EJ22 heads?

Subruise Posted June 30, 2013 Share Posted June 30, 2013 research cam grinding to get a grasp on why. but, as I understand it, you are basically moving your power band around, based on what kind of characteristics you want your engine to have. low end torque or top end power. i believe lots of people building frankies install them because a) the engines already apart its a performance enhancing build, why not increase the performance a bit more. c) with added compression timing needs jimmied with (i think) hth Quote Link to comment Share on other sites More sharing options...
soobie_newbie67 Posted June 30, 2013 Author Share Posted June 30, 2013 whats the fuel octane requirement for a frankenmotor? Quote Link to comment Share on other sites More sharing options...
quazi Posted June 30, 2013 Share Posted June 30, 2013 In other vehicles I've found that higher compression, a hotter cam and advanced timing always = higher octane requirement. JW Quote Link to comment Share on other sites More sharing options...
Subruise Posted June 30, 2013 Share Posted June 30, 2013 run premium, theyve been run on less. but run premium.. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 30, 2013 Share Posted June 30, 2013 Some people have run into idle and low end power problems using the reground torque profile cams with the Frankenmotor. The concensus is that you need an ECU tune or some other form of engine management to make the combination work. I'm not sure about the high end profile, there might be better results without a tune. In general people who build a Frankenmotor are very happy with the stock cam, which needs no tuning to make the engine run well. Quote Link to comment Share on other sites More sharing options...
