Yeah, as others have said - awesome stuff DB !!!
I like the comment on the video about the engine being "VW aftermarket 2700cc"... the new King of Understatement I reckon.

This is my 1972 Superbug with my own Megasquirt fuel injection setup. Scat 1915cc engine with counterweighted 69mm crankshaft, 94mm pistons,
pro-street heads with 40mm x 35.5mm stainless valves, C35 camshaft with 476” lift, 1.25:1 ratio rockers, 8.5:1 compression and 12 ½ lb lightened
flywheel. Twin 50mm Ford Laser throttle boddies, 270cc Nissan CA18ET Turbo injectors, twin Holden Commodore wasted spark coils, 36/1 toothed wheel and
Ford Falcon crank angle sensor, cold air induction, custom 4" muffler with twin baffled 2 1/2" tips. 78HP at the wheels at 4900rpm on 94 octane
fuel. Gets 8.0L/100km on the highway and 11-13L/100km around town. Oil temps don't go over 97C and CHT under 350F. At the 2012 Warwick drags I
managed an 11.537 at 59.44mph in a 970kg car (without my 92kg lard arse body) and won my four heats. Currenty fitting an AMR500 supercharger and
hoping for 5-8psi of boost and 30-40hp increase in power (hopefully!!).

Thanks Gracey. I tried to attach extra pictures but I must have stuffed it up so I will do them one at a time.

Here is the engine without the cold-air filter box. Note that the AMR500 supercharger still needs the intake plumbing and blow-off valve to be fitted.
I have had it running and boy is it LOUD. It makes a screaming noise that can be heard in the next street.

1915cc with AMR500 Supercharger
Finally put my blower conversion on the Dyno. I was very happy with the results. The engine is extremely responsive and has grunt right through the
rev range. It is soooo much fun to drive on the street.
Scat 1915cc, Megasquirt ECU & custom fuel injection, E85 fuel and AMR500 supercharger. Made 116hp at 4900rpm but had a minimum of 110hp between
4000rpm and the rev limiter at 5700rpm. Maximum torque ran between 2500rpm and 4000rpm and peaked with around 525lbs of tractive effort. As a
comparison, a standard 1600DP makes 38-40hp and 250lbs of tractive effort on the same Dyno. After the Dyno session I found a loose L/H inlet manifold,
plus on the data logs the air-fuel ratio was in the 10's (quite rich) above 5000rpm so there may be more in the old girl yet.

Thanks. The boost varies depending on revs. On the dyno run, the boost starts at 7psi at 2100rpm and then dips down to 5.3psi at 4100rpm and then
climbs to 10.9psi at the 5700rpm limiter. Since I am using a positive displacement blower, the actual air getting pumped into engine cannot vary, give
or take pumping loses, etc.
The boost pressure that is registered on a gauge is just the restriction of flow of the actual air getting pumped through the intake system, cylinders
and exhaust system. So I believe that the boost pressure is not actually dipping in the mid range. That is where the engine is at it's most
efficient. On my Scat 1915cc engine the intake plumbing size, intake port size, valve size, cam profile are set-up for max torque in the 2000-3000rpm
and max power at 5000rpm. So in summery I think that if I ported the heads, fitted even larger valves and fitted a more aggressive cam suited to
supercharging, then I would expect the boost to be more linear and the power would increase. An intercooler would really help as well but there is not
enough space.
If you want to see the datalog from the dyno pulls then please contact me via email at thieledj@optusnet.com.au and I will send it to you (was too big
to post here).

Intercooling is always an issue for Krauts.
Your smallest and most flexible option would be a water cooler (which I use on another application) A 600Hp cooler is about 350mm square by 120 thick.
Can type cooers are quite small and could be placed under the back seat or something like that. The piping length is irrelevant.
Cooler radiator placement and piping mightr be a challenge tho.
the gains just arent there tho to justify the setup cosats and time on such a low pressure combo tho.
Best alternative would be water injection. It would work ok on this setup. Use a PWM aux op on ur ECU to drive the pressure pump for a fully
progressive setup.
again, nowhere near necessary on this combo tho. easy enough to tune around via inlet density anyway.
Nice looking rig m8

I had investigated using a water-to-air intercooler but as you said, the cost and space were an issue. I still wanted to be able to close the deck lid
and have the car look standard. I have experienced manifold air temps of up to 150C with the highest readings being under deceleration. So to combat
the high temps, I converted to E85. That required larger or additional injectors. There were four 270cc injectors in the inlet manifolds and I
installed a 170cc injector between the throttle body and the blower and then another 170cc unit after the blower. The MAT sensor was installed close
to the air outlet of the blower. Unfortunately the reading from the MAT sensor were incorrect unless decelerating as the fuel was cooling the sensor
and giving an incorrect reading. The high air temp melted the MAT sensor on the drive to the dyno session so I have now moved the sensor to just above
the L/H inlet manifold. I will see what the results are after the new fan arrives. I had installed water injection early on when I was using petrol to
combat the inlet temps and also the detonation that I was experiencing. It is probably not needed now but it doesn't hurt to use it. Yes I am
controlling the water spray with the Megasquirt ECU. The injector prior to the blower has now been moved to after the blower into the position vacated
by the MAT sensor. I guess we will see how it all goes.
Hooroo

Those sky high IAT's are a mystery tho. Something is wrong in my view.
With tha TB as a pull-thru closed, and close to absolute vacuum behind it, there isnt anytbing to compress and generate the heat and b ugger all
airflow to remove the heat.
Your pipework is pretty large, but just isnt subject to that much radiated heat with the zorst pipes exiting below........
Its under 4Deg.C temp rise per psi compressing air, ignoring any additional mechanical heat sources so how the temps are being elevated that high in
the inlet and the fact that youve had to get so funky with additional injectors is very worthy of further investigation.
Good luck with it tho. its a very cool installation!!!

That was my thinking when I converted from blow-through to draw-through. But the blower still generates excessive heat. It turns freely and I have
checked the oil level. The water injection is between the butterfly and the blower inlet. The blower is running a pulley ratio of 3:1 and is spinning
at 2800rpm at engine idle, 9000rpm at 100kph and 16500rpm at 5500rpm. I guess this is what is causing the high temps.
Thanks.
David

Jeez. Blow thru with a superblower!!! Gawwd.
Thats a complete arse to get working at all with bloody blow off/relief valves hissing everywhere or belts flicking off. Throttle response ends up
pretty firey as well!!!! Instant boost once the throttle is cracked!!!
A M8 set up a blow thru turbo over supercharger on a crazy Pinto 2.3. it was idling at 12psi!!!!!! Had several 2" poppett valves set up to relieveair
pressure down from the blower and the thing wheezed like a big air compressor at idle and any time the throttle was shut!
If it didnt flick the blower belts off it went from idling to about 300 Hp the instant the throttle was cracked!
This was an (estimated) 700Hp turbo over supercharged thing and was undriveable.. I mean.. UNdriveable. it just went from zero to hero as soon as the
throttle was cracked.
Was funny to see it getting out of the driveway alternately idling or frying tyres. its all it did!!!!!!!

Got my graphs today from our dyno run last week.
I've only posted the HP vrs Boost graph but the air ratio graph looks good with a:f ratio at just under -12:1 alomost all the way thru the rev range
and the other graph is the tractive effort which pretty much followed the HP graph and peaked at around 1030 lbs force.
Not a bad result for what is basically a stock EJ20 twin turbo out of a 1995 liberty. All I have done is eliminate the PCV valve, pod filter on the
intake, straight thru exhaust from each turbo, exhaust vacuum crackcase extraction into oil catch cans, a reprogrammed Mines No2 ECU and an external
oil cooler/filter plus a front mount air to air intercooler. Details are under the non-vw engine forum.
This is running on 98 octane fuel and we are now going to change over to my 105 octane fuel which should improve the numbers even further.
Oh, and I paid $400 for the engine........
