has your brake fluid level dropped down a bit?

Yep it's a bit low. one of the rear calipers (the one I've not re-sealed) has a small leak, but only when sitting and not when braking. Result is that in the couple of weeks it's been sat the fluid's gone down a bit. It's one of the 'check each time I drive it' items, and wouldn't get driven like that.

What is the gold anodised dome Rob sitting on your n/s inner guard?
Ron.

that's a desk lamp Its' quite good (got a little halogen bulb in it) as long as you don't join the 2 metal bits together..


The filters are the £7.50 Amazon filters that Chris has on Lucky. The long untidy-looking red wire goes to the rev counter, and the rat's nest round the coil area is due to the ballast resistor switch not working in the starter motor, so the job's being done by a separate relay. That certainly improved starting! The PO wired new stuff in over the top of the old stuff, so I've no idea what's connected and what isn't

A white transmission dip stick handle,..that is the first one of those that I have seen, usually they are red. If I recall correctly, Harvey said that the very early transmissions had such painted handles.

Mine is white too

PAE's is white too...

Isn't PAE an automatic though?

That looks to be the later, smaller transmission dipstick, as used with the later flexible filler tube, which as you say are normally red. If that's being used with an early solid tube it can give discrepancies in the level. Early ones with the solid tube were larger and normally white. Red, white....Pah!! I have a lovely chrome plated one here.

what's this then? old, older or very old???

Lord knows if it matches my box or not. The box is definitely not the original, it's a 12D when it should be a LD1D2 box.

How are you getting on with them + the needles?

I think they're right at low throttle at least. Not sure whether to try KNs though....?

That's a late type dipstick, and it looks to be a late type tube as well, there should be a flexible section a bit further down the tube itself. All factory rebuilt boxes came with the PRND21 pattern after it was introduced, you couldn't buy boxes with the earlier pattern. Boxes rebuilt by non franchised specialists normally got rebuilt the way that they were. Personally all boxes I was involved with as over the counter exchange units were built up as the later pattern, and even now I'd prefer to do that, but when doing boxes on an individual basis that does add a bit to the cost.

Thanks - good to know these things )

Don't know yet. Haven't quite finished setting up the idle and mixture @ idle, but will report back once that's sorted

Hi Rob

I like the look of the red inlet manifold. Mildly surprised that you decided to leave the filters exposed in the engine bay rather than enclosing them in the existing filter housing. Is that purely an aesthetic choice, or anything else behind it?

As the plan was to make the whole thing breathe better, putting the filters inside a box with an eeny weeny tiny hole in the front of it seemed a backwards step to me. And I like the induction noise

It might be worth putting the box back on if it had a much bigger snout, but I can't really see an advantage over open filters, apart from the noise.

I decided to go back to the airbox set-up as my K&N's looked a bit on the small side, unlike your bigger filters Rob. I didn't appear to get any of the roar associated with the K&N's exposed, or now with them partly enclosed. It does however make the usual pleasing induction noise that the SU's make 8)

Goes like stink higher up the rev range. Possible slight reduction in idle torque but it's not quite set up , it won't take the 400 rpm idle any more.

Something (possibly filters) making a huge noise over 3000 rpm in the engine bay, sounds the same as the exhaust but coming from the engine bay. If it is filters then an enclosure might be a good idea, might be something else though.

Just whipped a plug out and it's grey.

If you go back to "Lucky Breathes Easy", you'll see that I changed the intake snout on the filter housing for a fabricated and much larger one to adress any possible breathing restriction. Ron has achieved the same idea by using an SD1 housing. With the filters inside the housing, the induction roar is still just about audible but is reduced to the level at which you can enjoy it!

Hi Chris

That might be the way forwards for noise reduction.

What does the induction noise sound like on your (or anyone's) free filtered V8? Mine sounds like the exhaust is exiting in the engine bay :shock:

p.s sorry for engine picture thread hijack!

 

[rockdemon]

The studs on the exhaust manifolds rust and rather than risk cracking the manifold they're often left under tightened...

Any engine Rob will only draw as much air as it needs, so provided the filters etc are of sufficent surface area to meet that criteria, then going larger will make no further improvement. The 3.5 litre engine based on an 80% volumetric efficiency has a maximum flow rate of 258 cubic feet per minute. The standard P6B air box has a 2" inlet which will flow at best 361 cubic feet per minute. Now if we assume a reduction due to air turbulence etc of 25% that still leaves a flow rate of 271 cubic feet per minute,..more than sufficient to meet the needs of the 3.5 litre engine. You could use the standard air box and attach a flared mouth like a trumpet onto the nose which would reduce the air loss and improve the efficiency in terms of the air path into the box.

Using your free flowing filters inside the air box will still see an improvement in terms of flow over the standard air filter elements and you won't have the constant induction roar. When I was doing my calculations and working out sizes, flow rates etc for my 4.6, it was said to me that placing the K & N's onto the elbows as you have done would eventually drive me mad from the constant hiss. The 4.6 (based on an 80% V. E) draws over 30% more air compared to the 3.5, evening running the engine on the drive with the airbox and elbows removed, the roar is considerable.
