Walter-Your car is an interesting read.I have a 2.7lt Type 4 in mine which I am in the middle of Injecting.What ECU is that you are using?Is the crank trigger wheel from another vehicle or custom made?My ECU uses a MAP sensor and is giving me heaps of agro because of the mild cam and dual 48mm Throttle Bodies.How many inputs does your ECU need to work?Keep up the good work.Regards Gary.

Thanks! It was fun to build too!

How many inputs? Well, air temp, water (=oil) temp for cold starting, VR signal from crank and TPS for load. Thats about it, but that is true for most any ecu.There are some more pics on keversite.nl of just the engine (parts): http://www.keversite.nl/fotoalbum/my_photos.php?id=3349 At the moment, she runs sequential (cam sensor is working)! and I did 10 liters to 100km at a steady 70 mph all the way from the way back from EBI where the heavy car ran a 13,82 sec on the 1/4 mile! |

A good collection of pics there-thanks.Good idea with your muffler-never thought to bend it in the middle to clear the body-made mine as well and had to make it a lot shorter to keep body clearance.Yes I am using all those inputs as well-with a single wire O2 sensor and the MAP.Think I have got the MAP beat now-made a small alloy tube with 4 small inlets and a 6 mm outlet and fitted 4 small one way check valves to stop each port robbing the rest of vacuum.Idles good now with 12 to 13" Hg and I fitted slightly smaller injectors-from 20.4 Lbs/hr to 18.25 lbs/hr.You would have to be very pleased with that 1/4 mile time and good fuel consumption as well.Looks like a pretty good package to me-good all rounder.

Just realised Aart-Jan shot a 10 second video of a blast down the straight at Zandvoort last year with the 2,7 engine:

That was the first session, credits for the cam-work go to Robin.
Won't forget that last session when I had the chance to be your passenger, for multiple reasons! Oh man, what a ride! |

Oh, yes its Robin's fault (of course )
You certainly had a rememberal run...pity the rod didn't wanted to play anymore. The run I did when I was alone in the car was about 5 seconds faster IIRC, so we were taking it (relatively) 'easy'. I needed to as I had promised this in order to have a passenger I will miss the N/A roar tho... |

Hi Wally, compliments on your bug.
I'm interested to know about your experience with the Saco hydraulic clutch when you fitted it to the 915 you ran a while back. did you use the entire kit as it was intended? or did you modify/swap parts. I've seen that you had a short arm on the gearbox end, did you change anything else? I too have the saco kit fitted to a 915, my troubles lie with the master cylinder I think. I had alot of trouble fitting the saco master cylinder into my type 3, I have the mk2 cylinder which is a bulky peice of cnc'd equipment, I also have the coolant lines for the EJ20T motor running through the gearbox tunnel. I struugled to fit the bulky saco master cylinder in the tunnel so ditched it infavour of a less bulky item. I'm not sure of the specifications of the master cylinder only the vehicle it was from and am convinced its not a good match. Anyway as my pedal is insanely heavy to operate I'm now contemplating at having another go at fitting the saco M/C. I guess what I'm interested to know is how you got on with your saco kit on your 915? How did the pedal feel? heavy or soft? Did you do anything special when fitting the kit? Thanks Kai |
