Supercharged Zetec.
As some of you will know I am in the process of having my Zetec supercharged. The supercharger will be a kit from Omex, who are also supplying the
rods and pistons, Bosch 044 pump, 690cc injectors and the map sensor/cabling. Flak Monkey of these parts is making me a backplate and spacer to take
the GTiR Nissan plenum.
Currently the engine is out of the car and at ATSpeed for the rods and pistons to be fitted. The gearbox is with BGH to be refurbed while the car is
at Fury Sportscars for other work (and the have the engine taken out and back in).
Once the engine is back in I will fit the supercharger, sort out the intercooler etc and then the car will be back to ATSpeed to be mapped.
This is the rolling road results for Omex's development engine which was running high compression than mine while but doesn't have the
cams & head mine does (CNC Heads head/cam combination)
Not very Locost but I thought I would share anyway.

This is the spec of engine that Raw were displaying at Autosport and is shortly going in their Demo Phoenix IIRC.
Looks beastful.

Richard at Omex has just shipped RAW's engine to them so my kit is next. So there will be two supercharged Zetec Phoenix lol.

thats a mental power curve  not sure my brain can react that quick......
Could i be cheeky and ask what the ball park cost will be?

anything that adds circa 200hp is not gonna come cheap!

I'm using the GTiR plenum which Flak has done for me.
The Jenvey one in the pictures of the RAW engine wouldn't fit in my car (they have had to use very short TBs to get it in) and it costs another
£650. Total cost for the conversion is going to be in the region of £5.5K (supercharger kit, rods & pistons, intercooler, injectors, pump,
building engine and mapping).

now this is what i call winter upgrades
will be awesome when done bet you can't wait 
the gtir plenum is popular with the turbo zetec boys as well and seems to work very well

The GTiR plenum is a good piece of kit and only £45 from a breakers.

Sorry to Hi-jack slightly but I am too building a supercharged Zetec engine. I have been building a MEV Rocket for about 15 months and after much
research decided to use the Rotrex C30-94 with forged internals. At the time I started with the engine build Omex did not offer forged pistons and
Rods so again with lots of research I got mine made by JE Pistons and PEC rods. Also their was no bracket for transverse application as it needed to
incorporate the engine mount. TTS agreed to design the bracket for this application. I will be running a Jenvey plenum and a single 70mm throttle
body and hope to make simular figures to yourself with slight head work. Have also invested in a Quaife straight cut close ratio gearbox with their
ATB LSD, so taking RPM to 8000, should be good for 55mph in 1st and 160mph top end - but I very much doubt I will see that top end !!
As I work in the industry, the car is full carbon fibre panels, seats etc:
Seats have recently been changed to this picture for pre-preg carbon seats
Car is a little further on than the pics above and is currently being wired with an Omex 600. Should be mapped and dyno'd end of February with
a bit of luck.
Will be watching your thread to see how your engine performs,
Jon

Some lovely work there...I'm pleased you changed the seats as the red ones didn't really suit the look.
The Omex kit uses the 30-94 as well running at 1.2 bar so it will be interesting to see what the figures look like .

Just found this pic of it at the Autosport show a couple of weeks ago with the pre-preg seats fitted:

A great deal of work has gone into that...Mine will be dirty in comparison.

And all the better for it, could you imagine trying to clean that once its got dirty
if you get circa 330bhp it'll be a quick car, my old one was heavier than yours and would still do a genuine 0-100 in 7sec's with road
legal rubber on a stoney airfield. Should help you hit that 150mph at goodwood

Hope so I was 6 secs off the FTD time set by a Nissan GTR last time out at Goodwood..extra top will help close the gap.

Hi jeff,
was chatting to the guys from Fury sportscars last night and got to talking about your super charge upgrade, one of the other chaps in the pub also
has a supercharged zetec in his GBS (robin hood) Zero and says his power curve tops out at about 230-240 bhp!!! so whats he done wrong?

small supercharger? or low boost. Omex do a low boost kit with runs 0.6 bar with standard internals and injection system which makes 220 HP on a
stock Zetec. Mine is a Rotrex 30-94 running 1.2Bar on Jenvey TBs and it has low comp forged pistons (10:1) and H section rods. With the large valve
head and the high lift cams this should push the car into the 340-350 range.

Hi, you said 10/1 CR, this is high for a supercharged engine, we run 9.5/1 absolute max with 20PSI

Yes 10:1 on 1.2 bar so 17.4 PSI. Which is pretty much the same as 9.5:1 on 20PSI (or 1.37bar)

You've lost me now! i was thinking of the static CR of the engine, a stock 2.0L zetec is 9.5/1. Normally a supercharged engine uses a lower
static CR. For example Cosworth YB is 8.3/1 CR.

Effectively when you boost an engine you increase the compression ratio by the amount of boost. So while the 10:1 ratio is higher the boost it is
running is lower hence there isn't an issue.
