I'm excited to see how you do!

Nice workspace ! What are the specs on the camshaft?

From their website:
"Unfortunately cam specs are not available to the public.
A cam card is supplied with each cam to assist you with dialling it in.
Lift figures can be provided on request and we are happy to work with you to help you develop your valvetrain requirements."
So I guess I will have o take their word for it

I was wrong. 462cc is what I have in there and it maxes out around 40% DC
Sorry

THanks.
Do they work well at low rpm with only 40% cycle ?

Oh cool,
What brand /part number are they ? Where did you buy them from?
I still need some high cc injectors
Regards

I got them from Mario at TheDubShop. He will give you great advice and hook you up with what you need

Meanwhile I got a few pulls done, playing around a little with water/meth settings and pulley size, and the max power I achieved was 78.2 @4440 rpm on the crank, with 142 NM @3330 rpm (105 lb ft). That was with approx 150 kPa or around 7 psi. I have seen a lot higher boost earlier.
It seemed as if I had a little belt slippage still, as the boost tapered off as the rpm rose, but all-in-all quite as expected.
This was a hot day (for Norway..) with 31°C (88°F) so the IAT was at almost 80°C before the water/meth kicked in and took about 40 °C out of it.

I add a couple of typical plots (not necessarily of the same pull The torque curve is interesting
Now I have to decide whether I keep this in the car as a daily driver for now (it is great fun on the road), and focus on fixing the 2110cc. Or start collecting parts for upgrading the 1600cc to see how much more I can get out of this setup.
Great fun !

Time flies
After I had it on the dyno, I have driven it daily, and I am quite happy with the performace. 78 hp may not sound like a lot, but compared to the 45 or so original hp in a stock 1600 is it quite a lot more fun
A couuple of weeks back I joined the local sports car club for a drive-out, and after some quite spirited driving trying to follow a couple of newer Porsches, I heard a "poff" when I hit the rpm-limit and the engine died instantanously. Thankfully the evenings are quite light here in Norway at this time of the year, so we ended up stranded just outside my hometown around 10 pm: A quick look in the engine bay revealed the problem: The trigger wheel had disintegrated. I believe the combination of excessive force due to warmer than normal engine after the spirited driving (the alu in the pulley expands more under heat than the steel trigger wheel) and the fact that I had drilled out the holes for fixing the trigger wheel to the pulley, led to weak spots that failed under the excess pressure.
Anyways, my wife picked us up and towed us home, and I simply removed the SC and the puelleys and replaced the pulleys and sensor bracked for one I used last fall before I installed the SC, and was on the road again the same night:

Re: AMR500 planning on a 1300cc - turning into a build thread
After scratching my head for a few days trying to come up with a better solution for the trigger wheel, my youngest son kicked me out of the sofa last night and said "dad, lets get the supercharger back on, 45 hp is sooo boring".
So I ended up trying a somewhat simpler solution for the trigger; I simply drilled 35 holes around the perimeter and istalled 35 steel screws in the alu pulley. The idea being that the screws themselves will have enough iron mass to trigger the hall sensor: And it worked perfectly
So now the SC is back where it belongs, and I can enjoy all of the 78 hp again

Cool,
Do you have a part number of the hall-sensor that you used?
