looking for advice on cam shaft selection for a 2056 cc motor that will be running the stock D-jet injection system.
sicne I will have big bore cylinders is there any recommended cam grind other than the stock one that will work well? also is there any other goodies i should consider to go along with the big bore pistons? thanks in advance (IMG:style_emoticons/default/icon_bump.gif) (IMG:style_emoticons/default/icon_bump.gif) (IMG:style_emoticons/default/icon_bump.gif) |

I have Jakes 9550 cam in my dJet 2056 and it works very well. Nice hp increase and cooler head temperatures.

yep, the raby cam is nice in my engine. You will need to have the MPS tweaked by someone or install a O2 and do the tuning your self.

My 9550 is a specific grind for stock injection, but that doesn't mean that its what I'll choose for you if you decide to buy one of my cam packages.
I have the 9560, 9590 and 9595 that may also be applicable based on your CR, elevation, intended RPM range, head work and overall goals for the engine. The 9550 is a nice cam and the most popular, but its not a one size fits all for every stock FI application. |

Not to get too side tracked Jake, but I plan on taking my 914 engine out this winter just for this upgrade. I'll use stock heads, with 96's, probably 8.5-9.0:1 with L-Jet (Not D-Jet). Which one of your cams would be best? Sea level driving. (IMG:style_emoticons/default/driving.gif) |

doesn't quite work that way..
I'll need you to tell me what you have for CR, valve sizes and other head specs.. I can't make a selection without this.. I also won't recommend settings because I then become responsible for your engine design and I can't do that.. You are the designer and builder and those things are up to you to research, learn and apply. I have engine kits that feature my full design. |
