Hi guy's,

As the title suggests really - has anyone used JW Developments (they advertise in Sprint), and are V6 Specialist.

I am thinking of giving them a call about what 'upgrades' can be applied to the 2.9EFi (looking into the possibility of getting 200bhp), as at the moment with cats and no major tuning I'm getting circa 160bhp at the flywheel.

Won't be doing this just yet though as I'm contemplating a body-off resto first.

Any comments or feedback??

Cheers

Chris

I did speak to John when I was living in the Midlands and he seemed to be very switched on about the various Ford V6 engines, he said he would have no problem at all in getting an extra 40bhp out my old 3000s engine, so with a decent cam profile and some re-porting of the heads and perhaps a remap of the ECU,I don't see why you shouldn't get 200bhp out of the Cologne engine.

Derek,

Going a bit (well sort of) O/T I notice from your profile you are considering a cosworth engine for your S - have ytou got any further on this??

This is also something I have comtemplated - do you know if any chassis mods are required etc?

Cheers

No chassis mods needed according to Micky P, try him on his profile, I have been out in an S2 Cossie.
Awesome

Hi, I have used John before, he built me an Essex V6 3l for sprinting and hillclimbing. He got 250 hp, went a treat. Cost about £4,000, and that was with a strong bottom end already provided by me.

Only problem with John is timing, he works on a slow timescale, so if you use him get commitment on delivery.

IIRC the bottom end on the Cologne is the weak point.

Great article on the Ford V6 engines in Classic Ford Mag last month. Talks about the differences between the Cologne engines and what you can do with them. Well worth a read.

Without getting into the Cosworth debate, as we would be here all day.

I am building an S3c engine for a friend at the moment, and in my opinion for you to acheive your 200bhp,it's very straight forward. A Piper cam kit BP270 or BP285(includes solid lifters and springs)£286, flow the heads (£150-£200) remove the cats and fit a sports exhaust. You shouldn't need to make any adjustments to the ECU for the performance gain you are looking for. I asume the engine you have fitted in your car has Lambda sensors, if this is the case, you will need so make an adaptor for them to screw into the exhaust, but I will help you nearer the time if you go down this route. I am making 2 adaptors for this S3, but I can do 4 if required.

If more funds are available, then improving the airflow into the engine will benifit enormously. Have a chat with Tim at ACT, he might be able to adapt one of his plenums to suit. A coleague of mine did just that, it only needed a plenum base plate made to suit the inlet manifold.

But without the plenum mod, you should easily make the horsepower you are after. Although the 2.9 isn't the best engine to tune, it will respond quite well to basic engine tuning.

With regard to the strength of the bottm end, it won't be a problem, they are a fairly strong crank, indeed the 4.0L unit is good for 450 bhp.

One word of warning though, these engines are very sensitive to vibration. If you look at the front of the engine, you will see a large mass of pulleys. This isn't an accident on Fords part. The early engine espesially suffers from unwanted harmonic vibration, and this is Fords attempt to stop this. And to be fair they haven't done to badly. It is VITAL then that when you take the unit apart, you must mark everything so that it goes back as intended. If you don't you will experiance some strange running! If you intend to dynamically balance the crank etc, then make sure when it comes back the marks are still visible. I use a small centre punch.

Hope this has helped.
