Moderators Zedman240® Posted March 9, 2010 Moderators Posted March 9, 2010 Yep. Could have written "CA sensor" or just finish the sentence with "CAS". Quote
BenZed Posted March 9, 2010 Author Posted March 9, 2010 Yes the cap is hitachi, casting is by Kameari and as I said before, twin bearings, different drive gear and yes chopper wheel/CAS inside. Quote
Riceburner Posted March 9, 2010 Posted March 9, 2010 Ben, Are these an easy fitment, what is the going rate? Quote
RB30X Posted March 9, 2010 Posted March 9, 2010 Grab some zoomed out pics next time your there Beno. cheers Quote
BenZed Posted March 9, 2010 Author Posted March 9, 2010 Ben, Are these an easy fitment, what is the going rate? They come as a kit with an Ultra ignition box, 62,750 yen in Japan. I didn't use the Ultra ignition box but set up my ECU to use the CAS in the distributor. Easy really as it just has 12V power and a signal wire. Can't use the factory tacho unfortunately. Quote

RB30X Posted March 10, 2010 Posted March 10, 2010 Thanks but I meant like a zoomed out engine bay shot to see how the whole set up looks now, not just the new dizzy. cheers Quote
Riceburner Posted March 10, 2010 Posted March 10, 2010 Wow thats a lot of clams! Is it worth it, improved performance? +2 Would be great to see an installed pic of engine bay! Quote
BenZed Posted March 27, 2010 Author Posted March 27, 2010 Going through some more tuning on the car. Turns out that my alternator has not been maintaining consistent voltage, so I just fitted an 85A item with a built-in regulator. Saves a bit of weight too as you can ditch the big regulator box on the inner guard. Going through the tuning process again at a different shop confirmed that the figures on the original dyno graph were representative of engine power, not power at the tyres. You'll have to ask Pulse why their dyno is set up like that. On 98-octane we couldn't run much ignition timing, which limited power to 151kW at the wheels. With 102-octane unleaded race fuel it made 160kW and also gained up to 15kW in the midrange. Quote
tbscobraZ Posted June 30, 2010 Posted June 30, 2010 What sort of alternator was it, bosch? I'm after a replacement and I'll need the 85amps. Quote
NZeder Posted July 1, 2010 Posted July 1, 2010 On 98-octane we couldn't run much ignition timing, which limited power to 151kW at the wheels. With 102-octane unleaded race fuel it made 160kW and also gained up to 15kW in the midrange. You need more valves for 98 to run more advanced ignition timing 2 valves does not cut it with that low of octane on an engine with good amounts of compression (more than 10.5:1) Quote
BenZed Posted July 1, 2010 Author Posted July 1, 2010 Yes, there are limits to 1960s head designs. I may change to E85 fuel later, but that will mean bigger injectors too. Quote
PZG302 Posted July 1, 2010 Posted July 1, 2010 Ben, just gone through that exercise with my motor, getting 195.5rwhp @5600 and 212 ft/lb of torque at around 4000 using 98. Timing is retarded at the moment due to number 2 plug running too hot, probably not flowing enough through the runner for number 2. Had the choice of live with using 98 or spending big dollars on decent fuel. A couple of tweaks with the dizzy, swapping the 280ZX module for a bosch module should fix the flutter and I am also making some changes to the intake, some heat shielding and moving the pod filter from in front of the radiator to the throttle body, should get me over 200rwhp and a bit higher in the rev range, somewhere near the 6500 mark on 98. At this stage I will be sticking with the 98 octane fuel as its easy to get on the way to the track, I just fill up the ute and Zed at the same time, and if work is paying, on the same fuel card. With the next rebuild I am looking at updating the Haltech F9 to Motech for fuel and ignition and running coil pack with no dizzy, should give quite a bit more. I will then look ata the cost of running a proper racing fuel fro the number of events I do a year, my engine builder has warned me off using ethanol, apparently a lot of the cub racers are having reliability problems with the E85. I can still run the standard injectors with no problems in being too high up the duty cycle, at this stage. Quote
tbscobraZ Posted July 1, 2010 Posted July 1, 2010 Any chance you could find out the part number and was it bolt in or did it need mods? Thanks Tom Quote

I can still run the standard injectors with no problems in being too high up the duty cycle, at this stage. My tuner reckons I won't gain anything by going to multi-coil ignition, so I'm not going to bother just as an experiment. Some of the problems people have with E85 are caused by the variable quality of E85. Sometimes the 15% normal fuel in it is rubbish 91 octane, sometimes better. ET Race Fuel sell it with their own 98-octane race fuel making up the extra 15%. Also some tuners don't run it rich enough... Quote

BenZed Posted July 28, 2010 Author Posted July 28, 2010 Here's a pic of my mistress, who strangely was invited to my wedding. Quote
RB30X Posted July 29, 2010 Posted July 29, 2010 Congrats Ben. Did the Zed sit at the bridal table too?? Quote
BenZed Posted July 29, 2010 Author Posted July 29, 2010 Congrats Ben. Did the Zed sit at the bridal table too?? Couldn't fit her through the door Quote
luvemfast Posted July 29, 2010 Posted July 29, 2010 Congrats Ben. No offence, but she can hardly wear white. Word is, she goes hard. I'm just saying...... Quote
BenZed Posted July 29, 2010 Author Posted July 29, 2010 Congrats Ben. No offence, but she can hardly wear white. Word is, she goes hard. I'm just saying...... Has previous owners too Quote
acf321 Posted July 29, 2010 Posted July 29, 2010 Hey Ben ... Love the wheels mate ... F8's look hot on these cars in my view ... and yes i'm biased ! Quote
