VXT Tuning Limits
Discussion
"Without getting too silly and compromising reliability, what sort of outputs have been achived on VXTs?"
I have been on a few meets inc the VX national etc and not met anyone with a genuine car over 300bhp. TMS stage 5 should be reaching over this level but his car has been "under construction" for quite a while now. There maybe one or two that have had this done but I've not heard any definite reports.
A stage 2 is is easily the best VFM with stage 3 being more sensible as cooling can be an issue if you want to track. Stage 4 takes it to another level with the new VXR turbo and injectotors but you will need a stonger clutch and while you're doing so it makes sense to install a lightened flywheel. Total cost about 5K or more. With a stage 4 at anything below 60 leptond or so you really need to be pointing the car in a straight line before full throttle. This can take away some of the VX's pleasure when driving out of corners but makes the car a lot more interesting on Mways.
If you are in the market there is a good value stage 2 on VX220org atm.

So stage 2-3 is where to aim then, not looking to ruin the dynamics of the car by having too much power for the grip available and want to keeps costs in check as the idea with the VXT is I can save some funds for the toy I get after that. bfg said:

Can't spot it, don't suppose you could post a link please? Probably looking to do it myself for the fun of it, even though it'll be cheaper for someone else to have already done it.
It's here as long as you are ok with green. It is a rare colour and does look good in the flesh.

The gearbox and cluth are going to be the limiting factor, the gearbox was designed to take 230 ft/lb in a vectra, as the car is a lot lighter 300 ft/lb is really the max you want to be putting through it, the clutch on the standard car isn't really upto the job of 184 ft/lb let alone a tuned car.
TBH, I can't see why so many people are spending thousands on tuning their VXT, they still won't get Noble performance or grip, but they are spending the same sort of money.

The biggest difference will be 0-100 times and overtaking times ... 0-60 will only be marginal but lots more tyre will be worn out
Overtaking it gonna be the thing for me, missing the power of the Cerb when visiting the opposing lane! 0-60 is always useful in the pub though, especially when your mates all have TVRs

I'd see a tuned VXT/Elise/Exige as very different propositions to a Noble TBH. I have huge respect for the Noble, but don't see them on the same page. The value of the VXT to me at the moment is the (comparatively) low running costs, so I don't want to ruin that by taking it beyond the limits of the drive-train, but I do see it as a bit underpowered and from my experience so far it could happily take a little more grunt.

I know that nobles are quick but a vxt with stage 3 or 4 can't be far behind with 280-300bhp per ton? Surely a tuned vxt would cost significantly less to buy and run. Plus there's the kit car styling to be considered - admittedly subjective. bfg said:

I like both and they both have handling. BUT, the Elise chassis wasn't designed for 300bhp where the Noble was, so it will handle better and be able to put the power down.
It's a matter of compromising with the tuning IMO, if the cost of the mods and the additional insurance premiums is above the upgrade costs of the car you really have to start thinking about it.
For me, a VXT at around £16k and perhaps £3k of tuning over a few years makes sense, as cost and servicing will still be way below those of a Noble.
