Is this the one?
Fuel injection kit Looks promising... I thought about that kit when I got my new engine. but I got 40 ida's for budgetary reasons... maybe some day. |

Is that plastic fuel filter, in the pic, under 30 psi constant pressure?

I have not looked at it either in the catalog or in person, but a local shop here in Sac, IPB Autosport removed one a year ago to put carbs on a 914 because neither they or the cars owner could make it run right.

Certainly looks like the CB intakes. Looks like George has mated this to injectors and and crankfire for a turn key solution. He shows it for all years so he must be differentiating by injectors and map. A little pricey for sure but a nice solution for an elderly DJet. There are so many NLA components now that it seems to be either carbs or aftermarket FI. A question for the head gurus. Is the plenum really the constriction on our cars? Seems to me that that no matter how much air you blow through the plenum at some point you are going to be restricted by the heads. Is there really that much constriction in the plenum that you could get big gains without doing the heads/cams? |

THe way I read it the plenum is the biggest restrictor or how does the itbs work so much better on stock heads? Itb's will always flow more air than long tube intake manifolds.

The TB's are CB but that coil pack is SDS. I saw the the dizzy and it had SDS crank sensors. I guessing it`s mostly an SDS system.

A stock engine going from 90hp to 125hp just because you add PEFI is total bullshit!

It's either "crank fire" or "distributor". |

Really? I can't get 50% more power with just FI ? How about if I add the fuel magnet and intake tornado? Maybe the electric turbo? (IMG:style_emoticons/default/teef.gif)

I would rather just pay $2000 for the real SDS system.... oh, wait. I already did. (IMG:style_emoticons/default/biggrin.gif)
Once it's installed I'll see what difference good fuel control alone makes on the stock plenum, and then decide if I need to go bigger. But slapping injectors into Carb throttle bodies seems like a pretty cheesy solution. Mark D. The TB's are CB but that coil pack is SDS. I saw the the dizzy and it had SDS crank sensors.

The throttle bodies will help if you have enough motor to use them. I've seen Suzuki GSXR bodies mounted to weber intakes before. For the average guy i'm not sure they would help. Guess a dyno would be the only way to know for sure.

A question for the head gurus. Is the plenum really the constriction on our cars? Seems to me that that no matter how much air you blow through the plenum at some point you are going to be restricted by the heads. Is there really that much constriction in the plenum that you could get big gains without doing the heads/cams? The exhaust is the restriction. Work on that first. |

Plenum volumes are critical to RPM range.. I have used a stock 2.0 plenum on 2270cc engines up to 145HP,above that its pretty worthless. The 2.0 Bus plenum has proven to be more well designed to me, in back to back comparisons on the same engine.
With a plenum based system camshaft specifics are absolutely critical at low speed and idle. Cams set up for a very high manifold pressure will give the best vacuum signature thats necessary for a MAP based common plenum to be effective and tunable. Generally the lobe separation is the key.. That said, George's system is SDS driven with some CB hardware. I almost had a chance to tune one for him a month or so ago on my chassis dyno. BTW- Its not so much a "restriction" or "constriction" as much as being less than optimum for certain RPM ranges. I just finished the revitalization of the engine for my 912E. Its a 2056 that is being built for MPG, smooth running and 90 miles per day commuting. I optimized this engine for air conditioning and to utilize a stock 2.0 common plenum. I am using a new system that Electromotive has developed for us that is generally used on motorcycle engines for my PEFI solution. This coupled to the RAT/ Extrudabody throttle body and my seriously modified fuel delivery arrangement that utilizes a fuel distributor rather than fuel rails should fit the bill quite well. (IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-1095-1285535649.1.jpg) I changed the cam in this engine from a RAT 9530 with a 105* lobe separation to the same cam with a 112* lobe separation. The previous version supplied me with 160K miles of trouble free, reliable performance. It was worn but had much more life in it when I tore into it as you can see here. http://www.aircooledtechnology.com/index.p...&Itemid=112 This post has been edited by Jake Raby: Sep 26 2010, 03:14 PM |
