BHP change for TD5 centre box delete

Trying to get my disco TD5 centre box delete notified to Churchill, they say they need to know a number for the change in BHP ("let's assume it's more" is not specific enough for them)

1. WTF?

2. Anyone know the answer? It's an otherwise bog standard 10P engine, auto box

It's the amount of stuff you can get into the engine that gives you the power, the exhaust is designed to remove the gasses and based on the engines intake.

Yeah, "hard to say" is about as close as I got. Problem solved anyway, just switched to NFU

NFU are supposed to be very competitive, but as they are just broker I've never used them, I always go direct.

You possibly find the due to slightly less exhaust restrictions you engine will spin up quicker, which is helpful.

Probably doesnt make a blind bit of difference power wise, but it may make a huge difference to your premium, as soon as the "any modifications?" box gets ticked!

But not all insurance Co's are the same.

Remember the fiasco a few years ago when some people felt they had to tell their insurer that they had fitted Winter tyres? The call centre muppets starting tick the "modified" boxes and peoples premiums went up! All sorted eventually when proper guidance was issued to the companies.

I had a Saab 93 a few years ago, the dealer offered a power upgrade, a proper manufacturer listed option, I checked with my then Insurance Co, they would have doubled the premium!

Interesting Mark, I assume you are talking about a Hirsh dealer fit remap? When you see these cars advertised they always say it makes no difference to the insurance as it was a factory option and therefore not classed as modified.

But then as this is a Td5 thread LR didn't list any performance enhancing, factory or dealer fit, options for the D1 or 2.

Hi Steve
IIRC It was a "factory" option £400 I think, but was actually done by the dealer.

Yes a simple remap but the insurance co listed it as a modification, hence premium bump!

The problem is that all their messing around costs them as people wont notify that they have had remaps and I am doubtful many get caught.

What about the person who buys a secondhand car privately, previous owner never mentioned a re-map, new owner blissfully unaware - could happen

Engine itself is still stock - no re-bores etc. They'd have to pull the ECUs and investigate...

Insurance is a contract of good faith. If you have no reason to believe it has been remapped then you have nothing to worry about.

If there is any doubt then of course you should - and I guess the date of a map could be discovered through diagnostic work.
