997 TT engine mods and insurance?

[W12JFD]

Hi all

Does anyone have any experience or knowledge of likely insurance increases if I modify my 997 TT? I'm looking at a remap and sports exhaust to get to circa 550bhp.

Thanks

Depending on insurer, you can expect an increase anywhere between 10-20% of your premium I would think. Some insurers won't give a hoot (the more specialist ones) and some will rape your wallet for all it's worth (the more common or garden ones).

On my 996 turbo, Groupama would allow me a 15% power increase. I had this done about half way through the policy, and it cost me about 18% of the annual premium.

However - this year I changed insurers (now with Chaucer through Pace Ward) and the turbo is costing about the same as it did before I got it mapped.

Wish I could have this luxury. My company refused to touch a modified car. Cheapest quote I got was over double my existing premium. Mind you, I live in Northern Ireland. Insurance blackhole.
