Dear Chris thank you for the good advice and quick service. If all the people doing things with cars would work like you do, things would be a lot easier. No worries, Its always a pleasure.

Westfield 3.9 Efi modification. Part II ( it has already had the plenum & Stock filter-box changed ) Here are a few pictures and the story on the engine modification of my Westfield 3.9 Efi (factory build).

After a lot of reading on your Website and few phonecalls /e-mails I knew what I „needed". After I placed my order the following parts were delivered very soon:

After unpacking the first thing I did was also the easiest thing to do namely put the tornado eprom into the ECU.

"The tornado chip as fitted"

Ported Stage 3 heads,	Standard Intake Ports
"The difference to the gasket is quite big! See the black lines"

Until now everything was very easy and comfortable cause I could do it in my cellar where it is relatively warm. The work on the car had to be done in an unheated shed wich is not so funny at around 0° C. The dismantling of the engine was not so difficult except for the removal of the two studs that attach the sump to the timing cover. The engine looked good inside with no deposits at all, as you can see in the pictures (no wonder after only 10000 miles). During the removal of the cylinder heads I heard some strange noises............lots of carbon deposits braking loose and falling into the cylinders. Look at the pictures and imagine how that would have looked after 20000 or 30000 miles!

Next the rocker shafts, conrods, lifters and camshaft were removed and two holes drilled in front of the lifter gallery to aid oil feedback to the sump. Then the new camshaft was fitted. When I tried to fit the trust plate this wouldn't fit anymore. After a short phonecall to Chris I learned that this isn't always fitted so there was no problem. After fitting the heads, lifters, conrods and rocker shafts I checked the preload. At 2,5mm this was a bit to much so I needed some shims (wich I should have ordered in the first place). So another phonecall and 4 days later they arrived.

"After setting the preload the gap between head and rockers had to be filled with some shims"

"When I tried to fit the trust plate this wouldn't fit anymore. After a short phonecall to Chris I learned that this isn't always fitted so there was no problem."

Before I could fit the timing cover some material had to be removed (see picture) so the duplex timing chain would fit. Fitting the rest of the parts was no problem except for the exhaust wich caused a lot of cursing and yelling. Next I adjusted the CO preset voltage on the air mass meter to 1,2 Volts and adjusted the throttle pot to 0,33 volts.

After everything was put together and no parts were left I put in some oil and water, and started the engine without the fuel injectors connected and waited for the little red light to go out..........it didn't. After carefully checking and rechecking I noticed that the little red light was the generator light and not the oil pressure light. This seems to have been omitted by Westfield because there´s a oil pressure gauge (wich wasn't connected because of a major dashboard rebuild). I don't think this is a good idea so I will fit one very soon.

Well, after connecting the pressure gauge and cranking the engine it showed about 2 bar, so I connected the fuel injectors and started the engine. It started right away and, except for the empty lifters, made no funny noises. I left it running at about 2000 1/min for 20 minutes checking for leaks and giving the camshaft a chance to run in. After that I adjusted the ignition timing to 8° BTDC at idle an took of for a short drive. First impressions where very good, maybe a bit less torque below 3000 1/min but it´s very difficult to tell if you haven't driven the car for 5 months (I only drive it from April until November). After driving for 20 miles or so I did some performance tests (60-120 km/h, 100-160 km/h) and noticed the car had become significantly slower from 60-120 km/h in 4th (6.8

instead of 5.6 sec) and 5th gear (9,6 instead of 7,6 sec), a bit slower in 3th (4,3 instead of 4,1 sec). 100 – 160 km/h was exactly the same as before at 6,65 sec. The top speed of 217 km/h (135 mph) also showed no improvement. Well this meant that there was definitely something wrong, but what?

After looking a bit at the car, thinking a lot about what I could have done wrong and calling Chris for some advice I came to the conclusion that it had to be the ignition timing. So I checked it not only at idle but also at 4000 1/min where it should be 28°. Of course it wasn't. It was only 20° ! This means the distributor only gave an advance of 12°. So I set up the timing at idle to 16° (I know it´s a bit too much but not so critical with a 700 kg car) so total advance was 28° at 4000 1/min. The next testdrive showed the beginnings of it´s true potential: 60-120km/h in 3th, 4th and 5th in 3.75, 5.8 and 8.4 sec. 100-160 km/h in 6.1 sec and no chance putting the power down in second gear ! This is how I thought it should be. So next I will be taking the distributor apart and modifying the advance curve so it will give about 20° of advance.

As soon as I have a power curve and some pictures of the complete car I ´ll sent them to you.

Regards and thank you once again,

William
