Just got back from having the VVT set up.

The photo upload has stopped working again So will post the Dyno graphs when I find
a suitable hosting site.

Around 250 starting at over 200 at 2000rpm.
With the VVT set up as Jaguar from the factory, we got the rated 240bhp, it looks like
Jaguar neutered the engine, possibly for emissions????

I think on at 1800rpm with 60% TPS and off at 5800RPM.
Strangely the Jag setting is on at 5200rpm, according to one of the Jag manuals, and that
gives 240bhp as per the specs.
The engine had been mapped at the standard settings, but needed a lot more fuel added at the optimum settings.

Really good to know that the ST200 inlet hasn't restricted the engine!

How much more fuel could the standard injectors put in?

I've bought a set of 6 hole mustang injectors for mine,picked them up for what it would cost to get the originals refurbed so thought give them a go.

Not sure, will have a look at the settings, I think they are on about 85% duty cycle. They are around 240cc/min

No Rush Warren, it’ll be a long parts gather, hiding the total cost from swmbo

That is seriously impressive output for an off the shelf engine, especially one normally used to lug an executive car up and down motorways. 90bhp/L without anything more than an engine map!

The problem is this is making me excited to get mine built, but I'm doing the kit car thing in reverse. Currently dismantling my second donor, so starting off with a car and ending up with a kit.

Only just, I had to fit a SAAB idler pulley to clear the chassis. There is 20mm clearance at the cam covers.
Doing it again I would fit an electric water pump, so no need for idler pulleys.

Once the engine is stripped of unwanted parts it's pretty small tbh,I can drag mine around the garage with ease

Yeah I've gone for EWP,never used one before but like the sound of how the controller works,faster warm up from cold is a bonus,the controller just pulses the pump at set intervals until the coolant is nearly at your target temperature set in controller.
With these engines having a remote thermostat the EWP set up makes the pipework set up much easier and neater too.

Incase anybody comes across this thread in future and is interested in the weight of the engine heres some idea:

Bare engine with just small Denso alt fitted=120kg.

As above with ST200 upper inlet manifold and ST200 solid flywheel =132kg.

As above with RX8 6 speed gearbox and Mondeo 240mm clutch=181kg.

On the St220 the water pump is driven from a pulley on the back of the head and is prety compact. But that means more plumbing like a Zetec.

I did test fit the adapter plate last week end. One of the locating dowls is in a differant place.

I hope to get started on the wiring loom Easter Monday as the wife is working
