after owning a vtr, i can pass judgement on how they drive, especially in comparison to a vts
rolling road graphs on standard 8v engines do show a decrease in torque towards the peak of the rev limit

3300rpm is no where near the rev limit

which is my point
after 3300 a decrease is shown.

Ill assume what I like thanks. You seemed to assume plenty about me.
I know how businesses work, I should do, I run one lol
Insurance is something someone has to have to drive legally, its not a case of if I dont like how they operate, dont buy. Its something that is needed, they know this so can basically charge what they want.
If someone was to say ok, were going to charge you £4 a litre of water from your tap, bottled water is to rise to £5 a litre, I could say to you, if you dont like how they operate, dont buy the water.
How would you get washed though? Brush your teeth, shave? Have a cup of tea or coffee. Dont like how they operate, dont wash simple.
A better example would probably be petrol, as from tomorrow petrol rises to £3 a litre. If you dont like how they operate, dont buy. Will you walk or cycle and not drive or pay what they ask because you basically have to?
Get my point?

You said "Towards the peak of the rev limit" so about 5000rpm+ at least ?

My point regarding your insurance was that if you cant afford to insure a certain car, then get a lesser model which you can afford to insure

I'll make it simple:
peak of vtr engines torque = 3300rpm
if thats the peak, than after that would be a decline.
5000rpm and higher is after peak, thus a decline in torque

5th gear really shows the drop in power, once up to around 3300rpm (not sure what speed that'd be) when you try and pull the engine has no power to do it
where as in a vts it pulls fairly easily up to around 5500rpm before it begins to struggle

at above^ isnt this also due to the gearing of the VTS compared to the VTR. VTR gearboxes' priorities was top end speed (even tho its still miserable) while the VTS gearboxes' where for quicker acceleration?

Standard stuff strangles the revs.
Like try breathing through a thin straw, its quite hard. Wider straw its much easier. Therefore bigger bore exhaust etc the gases escape easier and rev better.

This kinda helps me in a fair bit to see my car in a way.
Because i compared the size of the milltek bore to the Supersprint bore - and its a huge difference as the milltek is a somewhat bigger bore, but last time i had a breather filter on - the oil pissed out of the breather filter which i dont understand why it should have..
But the only problem with Cam's is that they are very hard to get installed arent they?
from what ive read, youll obvously need all the gaskets, a new timing belt and pulley, obviously the new cam, waterpump etc etc, and obviously an new ECU (i.e omex 600) which can run up to about £1000 of fitting of all that, without mapping it, and mapping at about £300 more?
Its allot of money, for about what 10 bhp? but then again its a noiticeable gain once all the breathing mods and exhaust mods are done.

Its not about the chances of it catching fire or being stolen its about your driving abilty and your attuidue towards it.
