Iva pass second time around at Kidderminster

Hi all

My Haynes roadster passed the IVA test second time round yesterday, for 30mins I thought it had failed so when the inspector came and told after deliberation it passed I was in disbelief until I had the certificate in my hands.
The test was at Kidderminster I only live about 5 miles away so I drove it there having never driven it before I was quite nervous but it drove lovely and put a massive smile on my face.

An interesting point on the first test, the tester said the fog light can come on again after the main lighting are switched off and on again if the fog light switch is left on providing the donor car didnít have that arrangement. This didnít sound right to me because I could have many donor vehicals.
First time round the car failed on

1. Manufactures plate had too much information, I included the engine number.

2. Plate for brake/clutch reservoir need to be stronger, I used the OBP L shape bracket bolted to the bulk head. I added another aluminium plate to the bracket making an upside down U shape.

3. Front indicators to far inboard, I made and extension bracket from a piece of 50x25mm box section and cover it with some spare track rod arm gaiters.

4. Exhaust U clamp and cycle wing (right down on the horizontal support) needed a radius of 2.5mm

5. Emissions where to high, I took the car bake to Dale at Bailey Performance (top chap) and the fuel pressure regulator (adjustable) was to high so that was swapped for a new fixed lower pressure regulator. Also the lambda was block up so a new one was needed, Dale remapped the car and fixed my air/fuel gage. Dale also measured the bhp the engine is an mx5 1.6 rebuilt by Basset down engineering Iíve added piper cams, GSX600 throttle bodies and a Westfield exhaust manifold, the bhp at the engine was 143.4 bhp and 114.8bhp at the wheel. Not the most power car ever by a long shot but Iím more than happy.
6. The rolecage side bars obstructed the side mirror rear view I had Caterham scuttle mounted wing mirrors. I bought some Safety Device rack mount clamp for Expedition roll-cage these clamp round the 45mm CDS tube and have a M8 thread which I used to screw some new wing mirror into. I had to file the edges of the clamps to increase the radius. I can now put the mirror quite high and get a good rear view.

7. I under estimated the gross and axle 2 weight.

At the retest everything was ok until the emissions, the engine was from a 1993 mx5 and the examiner tested the car as an MX5 and run a CAT test, the car doesnít have a CAT so there was no way of passing the test for the car as it is. So after the emissions test it was engine off sir and wait in the waiting room whilst I write up the Refusal notification. Whilst waiting I looked up CATís and the cost of remapping retest etc and was down in the dumps, after 30mins the examiner came out and told me they had been discussing the emissions test and as the car is Pre 1995 and although the engine is from an MX5 the car is not an MX5 so it passes. Needless to say, I was very happy for being given a pass.

When the examiner gave me the IVA certificate he mentioned the car drove really well around the test station and said something that surprised me, I must stress this was his opinion not mine, he said he seeís many Westfieldís and Caterhamís and he much prefers Caterhamís as they drive and feel much nicer than a Westfield and my car feels similar to a Caterham. To be honest I have little experience of either and I think theyíre both great manufactures probably light years on from my humble Haynes roadster, but it was nice to have the complement anyway.

Yes. Good work, sounds well built and set up too. Interesting the pre 95 rule was forgot!
