IVA = Fail
Had my IVA test in Birmingham today and failed on a couple of things but overall was a pleasant experience.
Fail points were:
1. Noise - Recorded at 102.5db
2. Brake performance - Parking brake efficiency.
3. Gear knob - must have radius of 3.2mm. (oooops! - missed that one)
4. Exhaust clamps contactable by sphere. Just need to rotate them a little.
Had a great drive back from the test centre. 
I will look into changing the Wilwood handbrake calipers for Sierra units to sort out the parking brake efficiency.
The noise will be my biggest problem, so i'm looking for a few pointers!

I think that's a good IVA result, can you re stuff the silencer, you may need a bigger can?
Think congratulations is in order - nice to see another Panther finished

Failed my IVA on noise as well, easy fix though. Rolled out a stainless Brillo pad so it was around 1" circumfrence by 14" long wrapped it
in chicken wire and inserted it into the exhaust in the lay bye outside the test centre. I also fastned a large washer into the exhaust secured on a
little L shape bracket this also reduced the noise and kept the wire wool in place. Dropped from 101db to 91db. Once I had got my pass certificate in
my grubby paws I took the whole lot out and dumped them in the test centres bin.
Well done on a good fail by the way.
Cheers ,Sean.

As Nearly done has mentioned, as this is exactly what track boys do
apparently the marshals find a lot of wire wool about the track

Hard luck!..but not bad as fails go.
If you go for Nearly Dones noise suggestion make sure it's secure; They don't like it when a hot glowing wire rat escapes across the test
centres floor!
I nearly mentioned the ger shift lever when youposted your pre-test photos. If it's just the grooves you could put some O rings around them.
Exhaust clamps are an easy fix.
The Powerlite handbrake is a bit short of leverage and the Fury has a modified lever that also reduces the effectivness. I added a multiplying lever
in the tunnel. It effectivly increases the leverage about x5. Nice snooth feel and holds easily on steep hills. If you've got the Wilwood
SmartPads then I'd get rid of them and switch to Mintex1144 pads as well.
Here's some links to photos of my lever arrangement...

The short cable is from a Mk4 Fiesta. I wasn't happy with the angle on the cable but otherwise it would have meant moving the rear cable
mountings. In reality it makes no difference.

You don't seem to have any sort of compensator mechanism to balance the L/R handbrake? That's one of the issues I need to address before
my IVA, how did you get away with that?
Not very Locost but very BEC

The link bar that the 2 cables are connected to is free to pivot in the lever. It's located centrally by a groove (and rubber each side) in the
lever but is able to tilt/pivot to allow for compensation. There's not a lot of compensation movement available, but it was ebnough to satisfy
the SVA inspector, although in all honesty is a bit of a bodge and causes slight flexing of the cable where it attaches..
In an ideal world I'd have mounted the 2 outer cable stops further apart to allow for a larger range of compensation but I didn't think
about it at the time. The whole secondary lever was an afterthought to overcome the limitations of the Wilwood h/brake calipers that worked out very
well.

Thanks guys, pleased with the test.
I will repack the silencer first and check it with a noise meter i've borrowed. If i can't get it below i'll try the quick fix or db
killer.
Thanks for the pics of the handbrake mod, I will have a measure to see if I can do something similar. Really need a locost approach rather than shell
out on a Sierra set-up.

Gear Leaver Surround
First Off, Well done with the IVA & Good luck with the Re-Test!
I know I'm acting a bit thick but I have looked at the previous IVA post pictures & I cant see what the problem is with the Gear leaver
surround circumference.
Would someone be good enough to to explain in idiot proof English please?

Hi,
It was the gear knob that I used that didn't have a 3.2mm radius.
I should have left the Ford one on.

Hi Niel,
Thats a good fail mate,though i am very surprised by the exhaust noise.
When my MK passed SVA,with your engine in and zorst on and it was a full 10db
below the limit It was also well below the limit at croft.
I have just repacked my can and the noise has dropped noticeably.
Well done though,get it finished off and enjoy the rest of the summer.
Andy

Good luck with retest, Just do what the people have mentioned before and you'll pass it no issue.

Ah, thanks for the clarification. As you say, not a lot of compensation! I'm planning to attach my cables to a short length of bar
to act as a sort of bellcrank with a rod end in the middle connected to the lever.
I've got the Willwoods too but seeing as my brakes are well used and bedded in I'm hoping I'll have enough braking force, it
certainly works well enough.
