Supercharger boost?

[grueni]

it`s just because i had to change the generator at the same time and how you see i have the regulator next to the engine (need the place for the carb over the generator) so it's just the test kind of wiring.
thats next to change in a free minute.

Nice job with the 40hp intake manifold. We used to do this mod back in the '60s when few performance parts were available What happened to the wiring in your engine compartment? It almost looks like a candidate for the "Abortion Engines" catagory

made of an old 48ida stack that was laying around.

now with 24mm venturi
120 main
55 idle
170 air correction
more acceleration pump lift

drives very nice

Where did you get the velocity stack?

[grueni]

So the first part is done, the engine how it is now:

Heads with 33/28,5 valves very well portet to 40hp manifold

Stage1 cam

TDE end pipes

Carb with stack + 22mm venturi

Rest stock parts just same weight...ect
Nothing amazing but drives very yery good.

I will drive it that way a while and than go turbocharge it.

step 2.
the heads:
i decided to use my stock heads with 33mm okrasa valves. they are so well portet (not by me) that i see no need to touch them at that point.
new guides, new intake seats, new valves, clean as hell.

the only thing i did is porting the beginning of the port to adapt a 40hp manifold and go one step ahead. from about 20mm to 22mm inner diameter. that is a little bit more than 20% more area and flow than stock.

i just have to cut the manifold and i will also not use the pre heating in fact of turbocharging.

no higher compression ratio nothing fancy. i will build the turbosystem to the stock engine dimensions that is is easy interchangeable.

i hope to get it close to 40 din hp that would be the perfect base for my turbocharger and my later goal.

next step is engine out, heads on + stiffer springs.
new clutch and welding the hole header.

after i sold the supercharger and feeling too slow i decidet the days to go turbo

it's the same engine like the supercharged one but maybe i will put my 33/28mm heads on or my 35,5/32 with 1,34 ratio rockers. depends on how easy and interchangable they are. the 33/28 heads will come with a 40hp manifold. the 35,5/32 with 32mm inner diameter.
easy setup.
pull through.

i will e there next year to hessisch oldendorf would be best.

if blauchen also wand a supercharger let me know.

Christan,

It's so funny I was following this thread before and I commented to a friend of mine about how nice that Diamond Green Oval was ~ not even knowing that it was my old car..............too funny!

I really like your friend's garage/studio, I need to fly over and bring a few of my sexy PiNuP models with me so we can shoot there, together with "Matilda". she will make a perfect calendar car!

TTYL, Alles Gute!

Tom

so its not the right place i know but maybe somebody is searching exact this for a nice powerfull 36/porsche engine.
in fact of the stuff i have for later builds i will sell my very very well done porsche 356 heads...i never gave up the plan using them on a 36hp but ended up now in fact it's not the right plan if i really someday will be at bonnvile and my secret weapon heads will have same totential+. so they can go...i will ship world wide for sure.

so its time to post the tlan for stage 2 of this setup

in summer i will open the case, messure everything, refresh the case and all wat needs some machining.

currentliy:
53 case std.
77mm AA pistons
stock rods same weight
stock unballanced crank
stock heads unported but with a nimonic exhaust valve 28mm
std rockers lighter
stock lifters and pushrods
stage 1 camshaft
porsche flywheel with 9 spring pressureplate and stock clutch
stock manifold changed with amr300 supercharger and modified 34pci carb
abart tip4 muffler
6,8:1 compression

made 70 hp at 3900 rpm and about 150nm from under 2000-3000rpm
with 0,9 bar of boost
drove it with about 1,1-1,2 bar all the time so must be around 80hp/165nm

stage 2:
same case but with full flow and external oilcooler opened für 83mm pistons and liners
crank i will use my dDPR 64mm counterweighted,ballanced and the matching flywheel + the ballanced rods all from my mymedusa engine.
pistons typ1 or porsche 356 with my 80S kolbenschmidt 83mm pistons
heads stock ported with 33/28,x mm valves new guides + a 1200 or 1300 typ1 manifold. same supercharger same supercharger rati. maybe another carb SU ore something. but first the pci34 with a 30mm venturi.
maybe with 1,35:1 ratio rockers but think i dont need them for my goal.
stage 2 camshaft
7,8:1 compression
the 9spring pressureplate will get some stiffer springs + stock 180mm clutch
merged 32mm header and csp retro muffler

goal is to open up everything a little to raise the peak hp from 3900 to 4500RPM and with all the stuff make it cool better with the full flow oil cooler and in fact of the less boost it will have.

goal is to reach 90-95hp at about 4500 rpm and more torque over a bigger range.

the heads:

compression raise will make about 10% more per piont
less backpressure will free some horses too
the raise from 3900 to hopefully 4500RPM will do the moste
the more cc also will do something + lowwer the boost that is less hp that the supercharger needs and less heat in the manifold.
100hp is not impossible but this would be the absolute top the blower should do in a daily driver mod.

the very simple way of calculationg back from the dynoed engine:

70HP/1,9 (boost) * 2,15(dayly driving boost)=79 hp
79hp* 1,1 (compression raise from 6,8-7, = 87 hp

87hp /3900rpm*4500RPM(if the hp gragh is kind of lineary) = 100hp

so if everything is done perfekt and the engine will breath for peak hp at 4500 rpm 100hp is not impossible
same calculation backwards for the supercharger as a airpump says 105hp is possible so lets see how perfekt i could get my goal.

That's my ex-beetle.

I was looking at a bunch of Aisin 300s today, but they were a little too expensive to make me buy one. Interested to hear about your idea for kits.

[grueni]

at the moment no, because the car is in wintersleep 70km away from me.
but also it will not help. fit a carb, make pulleys and than build the holder ... be very carefully in bringing everything in the right place. every mm every degree will make in instabil and will rob hp over the beltsystem. pics will not help. out it where you have room for it and make it strong.

currently i still have a 80% finishes amr500 set to sell für typ1 engines.
depends on rpm its a 65-130 hp setup with different pulleys. it just neet a t piece manifold an a idler and little work to the holder.

pm with your email if interested.

[beetlejooz]

Is it possible for you to post detailed photos of the mounting position of the supercharger to the motor and the brackets or whatever you used.

Im in the process of locating an AMR500 and a 1600SP.

I also think it is great that you have been experimenting with a collectable Fish M2 carburetor! Cool stuff!!

For some reason, I am fascinated by the folklore surrounding Charles Pogue's "Winnipeg", the Fish, and the other super mileage carburetor designs. Woodgas burning automotive engines, too.

Anyone else interested in high mileage carbs should start with this link: http://www.boni.com/fish/

[skyto]

I wrote that in hurry. I do have the accelerator pump, it is just the normal type, like 28PCI pump. The code that's stamped to the side of the pump is 72.

I was wondering if you still have the BMW type accelerator pump. You know these things already but I'll write this anyways for others to find.

The 700 engine had 2 cylinders. So it's ok to use dual BMW 34PCIs with four cylinder engines. But one BMW carb for 4 cylinders needs a different accelerator pump, especially when supercharged. This link shows the BMW accelerator pump is of the weak/lean type.

[grueni]

on a supercharged engine use allways a carb with accellerator pump or a pressure carb like an sc or cv40- but i believe they also have a pump. the cv40 that i used once had one. the way from the manifold to tha head is long and also you have uge jumps in pressure with a supercharger...without a accelleratorpump you will allways have a lean spot when hitting the pedal.

Thanks for the explanation..

For the accelerator pump, yes I mean the valve for (power?) fuel. With the NSU and BMW versions it's on different sides. Aftrer squirting the extra fuel the other one stays open and the other closes if the gas pedal is still pressed. Industrial versions may not have this valve. I have an industrial 32 PCI without the valve and I'm a bit lost with the jetting.
