Just as easy to make you one mate... want me to grab the bits for you tomorrow? You'd just need to have a length of wire, and a pint waiting

Adam, you still want one? Sorry I havn't done it yet.

And I reckon you are right Steve... island roads are different according to the sign...

I have the bits to make it mate if you can post wiring diagram!!!
Adam

I think this is wiring diagram you requested?

Thats the one Adam... or Ali... which values did I tell you to use? Gonna recommend Carl uses the same.

T/hink i got a 100k pot for mine, same as Ali's? What shall i set it to??
Adam

1k pot and 47k resistor iirc, the pot will be set to about 1/4 I think but you need to check the output from the headphone socket with a multimeter, try to get it close as possible to 50mV

Cheers mate. Will have a go soon.
Adam

Dude... I must have taught well! Those values sound spot on, and Ali's setup advice is spot on too, stick 12V on the wire that will be hooked up to hte renix/tacho feed, and adjust until you get around 50mV (+/- 5 or so).

Then hook up to the car, all two wires, one to earth, other to renix (make sure you get the wires round the right way though!

Blown my nerves now with streetdyno and my both computers.

The program simply SUCKS. It bugs my both computers, access violations, illegal operations..... you name it. Worse than those late 90's 16/32bit win95 programs, that didn't work for a bit.

I haven't got a closest look at a good curve, the best one started from 5000rpm, and ended at about 5000000000000000000000rpm, with result of 900hp/600Nm.

Isn't there a better program than streetdyno, i've tried to get my hands on powerdyn, but can't find it nowhere.

I'm 101% certain that your problem is not software but sample file you have recorded, I have experienced those odd rpm's too and there has always been logical explanation for it.

But there is program called Powerdyn, most of these graphs are taken from powerdyn actually so you might like to test that.

Also I can do curves for you if you send your recorded audio file and little info about weight, tiresize and what temp/airpressure was when you took recording

Here is pages where from you can buy Powerdyn http://jcdperformance.free.fr/powerdyn.htm

Translate via babelfish if needed.

But if you like I can do those curves if possible from recordings

Got some results here a while ago. Here's some curves:
http://koti.mbnet.fi/fredrikr/Volvo%20340DL/340DL.jpg

180hp@5700rm / 256Nm@4200rpm was the average from 4 tests on different even roads.

As you can see, the torque is awesome even near idling speeds, 140Nm@1100rpm, and stays good untill 5600rpm, where it drops totally, as does the power also after 5700rpm.

I think the torque and power drop after 5700rpm has to do with the standard exhaust system, that looks really small, compared to the "downpipe" of a 2,3L 16v GLT engine from a 740 volvo. As you may know, i used the exhaust manifold from a 740GLT and the "downpipe" from a 360GLT, and the downpipe seems to be the restriction here.

I have heard many comments on finnish forum that K-Cam is not giving low end torque, I don't agree:


I had 4 winter tires on trunk with wheels, half of exhaust, full oilcan, full coolant can and full windshield wiper fluid can, those liquids alone weights at least over 13kg, I'm about 107kg (yeh, I'm big ) and I set car weight to 1300kg. Transmission loss is still same 18%(this is measured from one 360 on rolling road, but maybe bit high indeed) to make comparing of results bit easier. Naturally put correct weather data as well as altitude. We got +25C clear sunny sky and no wind at all. I did test in same place as always to minimize errors in data.
Also I had 3/4th tank of fuel on board.

You can see how annoying it is that spark is cutting around 5000rpm...
But torque is coming fastly down, maybe my fuel map, but can be naturally original exhaust too, also this spark cutting could affect a bit to curve shape as I felt slight variance in acceleration speed around those rpm where it started to go down, then bit after 5000rpm BANG BABGBABGAGBABGBGABGBAB it starts spit fire from exhaust

OK, well, as the guys who came to the pre-BKV BBQ will know, a cam arrived in the post and was duly fitted on Saturday. We did some Powerdyn runs but couldn't find a level road, so did two runs, one uphill and one downhill, comparing A and K cams.

Also, I managed to find a quiet straight road yesterday, but there was a force 7 gale in force so the results were affected by the wind somewhat.

Here are some piccies that demonstrate the difference between A and K cams. Nothing else has been done to the car, except remapping to take account of the different characteristics. Something weird went on with the downhill runs because it has the A-cam down as more powerful






Here's the one I got on a reasonably level road, there were a couple of very slight humps but the wind was very strong, so I've done 1 upwind run and 1 downwind run and this is the average.


Many thanks to Chris_C for doing the wiring for the Powerdyn connections and also for teaching me how it all works. Also for his help in remapping after the cam was installed.

Thanks also to Foggy for help installing the cam and Ryan (1stRaven) for the use of some of his tools.

The videos on the calendar meet section from SteveP tell the story, but Foggy is definitely making a good lump more bhp (140ish as opposed to 125-130ish) , in terms of peak, but because hs bogs down so much in the first 2000 rpm I pulled away from him, even when he was in 1st gear and I was in 2nd

Andy, give me a shout on MSN, theres a button you can press that smoothes all those 'orrible lumpy bits on the graphs that I reckon are artifacts in the system. Seems to have been a worthwhile install though, those up hill runs do show a difference.

Definitely a worthwhile install - the peak power certainly is rather modest if you consider the 'real world' power. I think what we need to consider is what power stock 360's are making on LE-Jet, I'm sure it wont be the original 115bhp!
