Building a nice supercharged engine but need help please :)

[blink]

Hi everyone

just wondering if I can get some help and ideas on the best way to do this. I was having a good look around and searching for a good thread for info or ideas but couldn't find to much.

I have a 69 kombi which has a small little single port on a 3 rib gear box and its good and I like it but a friend of mine had a berry blowers AMR500 set up for a twin port that he decided he didn't want to use any more so I got it off him. later on I will change to a 5 or 6 rib that I have which I will get rebuilt but for the moment i will use the 3 rib. the Berrys kit I got is to use a Pict34 but was thinking I will go with the updated style which is using a DCOE40 carb.

The plan for the kombi is to tour around with it on long road trips and go camping, I'm in Australia and the climate is 40+ degree (104F) summers and down to 10 degrees or lower for winter (50) but does get below 0 and some snow.
ideally looking for a nice torquey engine that I don't have to rev to the moon.

So my first thought has been to build a nice 1776 with the blower on it but I'm not a 100% sure if that is the right size to go with but happy to hear peoples opinion or experience on what has worked will, the 1776 is just what I seen was as big as you can go with the AMR500

I have a few AS41 cases that I was looking at using and I will take them to a VW machinist to get them to check it over and bore out the cylinders for the larger barrels or which ever case is better.

I have a set of newish heads with about 5000kms on the but I don't know the specs on them so will have to dig them out and double check

The cam shaft I have gotten a dedicated blower camshalf which is made by engle with the specs JB200 – 437″ lift / 294 degrees duration / 112 LC


so my biggest questions are is the 1776 the size I should be looking at?

would using a vacuum advance dissy or non vaccum dissy and locking the timing be a good way to do it or would it be better to use an stand by ECU to manage the timing?

and what CR should I be aiming for ?

I have a heap of other questions but interested to hear what other peoples ideas or experiences are

I hope that makes sense

Thanks everyone!!

Hello.
WAAY too much cam for what you´re aiming for. You want a cam in the area of 276 seat duration and 235 @ 0,050" No more. 110-112 LC could be interesting to have, but not 100% nessessary.

I know that you have the blower already and want to use it but... for a Bus for long trips? That's an unusual combination for sure. Force feeding an engine in a heavily loaded Bus at part throttle for hours at a time sounds like a hot engine with high fuel consumption issues to me. But... I have not done it myself.

I think you would be happier with a turbo in the long run.

Hi Guys thanks for that

thanks ALSTRUP
the only reason i ask about the cam is just cause i got it with the blower, looks like i will have to find something a little smaller.

I was thinking the same but i thought i would try something a little different and my mate wasn't going to use it so it was a good excuse.

Thanks for that info
that gives me heaps of info to work on. i got a nice dissy i will get rebuilt and then set it so it doesnt give me to much timing.
i will have to have a look for a nice cam too, the w110 i have used in the past so will maybe go another one of them.
I will put a full flow system on the engine with a nice sized oil cooler thermostat and fan to help.


my thought with the gear box was just if im going to on the highway for awhile that it would be nice to be sitting at a nice rpm for the engine aswell as being close to the speed limit.

Should i be looking at just a 26mm oil pump?

[Alstrup]

A 26 mm pump should be sufficient. Youre not drawing any oil from the pump to anything else but the engine.
A draw through charger set up doesnt heat the intake up quite as much as a blow through, so I think it should be ok.

Hi Blink!

So, have you built your Supercharged engine? I am planning on building one too and any info would be good.
