Winter tinkering
Finally managed to get it out of the garage and take some half decent pics before.
New clear full size aero screen fitted, new headlamp covers, new reg, all bodywork done (bit of crazing), completely de-stickered it, flatshift as
already mentioned in another thread, airbox fitted to cut down the induction noise for trackdays (actually sounds better), lots of other general bits
of tidying. Can't wait to get back out in it for a proper drive!!

Looking good! Is that airbox a Pipercross? It looks like it has a lower profile than normal.
Cheers,
Raz
When thinking outside the box doesn't work any more, it's time to build a new box

Yep PX600, as you can see I've had to move it over where there was more space but it all fits nice now.

With an N reg prefix (95/96), silver on black plates might invite unwanted attention from the BIB.

Interesting to see whether those plates give you trouble. I have a stick on, but have stuck with standard colouring.
I notice that you now have quite long intake tracts, according to basic theory this may boost low end (with the obvious drop up top). Have you got a
wideband for looking to see if the fueling is affected. It might be interesting. If you haven't then I don't think there is any risk to
the engine, just interesting.
Looking very nice.

I know a few people with them on kit cars that havent had any trouble. Also know a lot of people who don't even bother putting front plates on!
If it happens it happens and I'll change them. We shall see!

I thought it may give a bit more torque. Not driven it yet so can't confirm, I doubt the fuelling would change dramatically but it may run a but
richer now? I may check the a/f ratio as I know a couple of people with the equipment, but not going full blown rolling road dyno session til
it's been cammed.

Looking good.
Is the air-box supported on brackets. I've heard of a few where they've pulled the throttles off thier rubbers.
The screen may prove to be too high in the wet. Weldermans was like that and looked good but wasn't practical in use.

You could go old-skool and do a plug chop to check the fueling in a crude fashion. Given you extensive work, an innovate LC-1 and lambda sensor would
be a cheap way of knowing where you are. I found mine brilliant when messing around with fueling (before I megasquirted the engine, when it became
essential).
Regarding noticeable torque changes, I think the "Backside dynamometer" is pretty much useless on BEC's. These cars are so
different to cars that we normally drive I suspect that detecting a 5% change is all but impossible.

i can only see that inlet duct reducing power

Any reason.......?
I can't see it making a noticeable difference either way. It's not a performance mod, it's to shut it up for trackdays and it has
worked so im happy.

Nice work! Looks neat under the bonnet, let me know how you get on with the airbox as ive been thinking about one for a while and curious if it will
improve/reduce performance over a sausage filter.

the number of direction changes and the convoluted bore of the pipe will add pretty significant drag to the incoming flow. the huge bore may
compensate for it, but it's still suboptimal.
a straight pipe to the duct at the front would be better, but if you're happy as it is, fair enough

Not going to argue but it's easier said than done, it just about fits as is.

My air feed is 3in and straight-ish, and I actually see a bit of ram-air with my map sensor. Also the inlet air temp is much lower on hot days (like
25deg cooler).
I don't know how restrictive those corners are on yours, but I would have thought you would gain much more from air temperature (and hence
density) than anything else.
You could build a little u-tube manometer (clear hose, bit of coloured water) and see what happens to the air pressure in the airbox.

Well I drove it today. Hard to tell whether it's any quicker than last time I drove it, but pulls very strong and sounds better so job well done
as far as I'm concerned. Either way, still f'kin mental.
