[DML] Super Charged PRV

[nicholden@xxxxxxxxx]

Hi all,

I am currently in the middle of fitting a supercharger to my engine. 
I have done ALOT of reasearch into the possible fuel delivery 
problems, detonation etc etc. I went to the extent of talking to a 
performance shop who had the software to do predicted fuel flows 
graphs working off the current known preasures, injector flows, boost 
preasures etc.
 
In the end i decided without modification to the K-jetronic to 
enrichen the mixture at higher rmp it would be more than possible but 
probibly not desirable for the chance of it maybe leaning out too 
much and causing engine damage. 
I have seen this first hand on a subaru WRX that came in for a miss 
at idle and slight smoke under boost. All the guy had done was put a 
HUGE exhaust on it off the turbo and under high boost it had leaned 
out and melted a hole in the side of the piston! I had seen a 
thousand other cars with the same exhaust and never a problem.

As my fuel system was needing alot of money spending on it anyway i 
decided to strip the entire system off including fuel lines and 
replace to whole lot with an EFI set up. I have had to modify some 
injectors to sitt inside the head as far as the originals and i had 
some costom rails manufactured. I will be purchasing an adjustable 
preasure regulator and probibly a microtech control module which will 
also have full control over the distributor timing. (i had to 
disconnect the vaccum advance and weld the bob weights up)
I will be making a custom manifold and i have a GM 3.8 litre throttle 
body with a throttle position sensor already attatched. I will also 
be fitting a bosch 'boost return valve' to the intake side, so under 
decelleration and at idle it will re-circulate the boost so the 
engine unlike most after market super chargers will not be 'boosting' 
all the time, lightening the load on the engine.

I am fitting an Eaton M45 blower due to the fact i already had it. If 
i hadn't for ease of fitting i would go with the same style as the 
one pictured on the web. Due to the nature of the Eaton i will be 
bringing the intake around the back of the engine and have a K&N 
filter sitting vertically inbetween the now empty valley and sucking 
air from the void inbetween the engine cover and the rear louvers ( 
the engine cover will need a hole cutting in it for this). As for the 
bottom pulley i am having one the original one modified so i can 
attatch another one to the front of it.

I hope for this to be almost finished in the next 6-9 months along 
with my RHD conversion and complete restoration, didnt realise the 
size of the job when i started! You can see a few progress pictures 
on the Australian Delorean web site

I was browsing some of the photos in my collection and came across a
photo I have of a huge belt driven super charger on a PRV.
Does anyone know anything about this?
I would like to know how well it works, how much it costs and
how hard it was to do.
It looks like they had to move the water bottle...
Thanks.
