Yep, both front arch liners flap about a bit and are badly shredded, however they do stay in place somehow and do their job.

 

The extra rubber on the car makes it hugely grippy (when they are hot - which is harder to achieve). If you remember, 2 years ago it was pulling around 1.4 to 1.5 sustained lateral G on good tarmac, Since then with the geo considerably improved I would expect the potential lateral G to be a bit more than that now. People who say my car doesn't handle and is only good for the drag strip are clueless, really clueless.

better start working out for upper body and core strength

[Mopeytitan]

With your wing Nev it should definitely handle, I imagine it must handle better than most vxs due to downforce created from it?

I'm not entirely sure about that, I think the wing adds a sort of "stability" at high speed, though I am still not sure how much downforce it gives, without some sort of measuring equipent attached to the coilovers it will be hard to know.

 

I might stick my micro camera in the wheel arch pointing at the coilover and then drive upto some speed and view the camera footage to see how much it squats. Presumably from the knowing the spring poundage, the MPH and the coilover squat distance it would be possible to calculate the downforce.

 

The problem with the wing is it really robs a lot of power (and hence speed), it's resistance is roughly a square factor in relation to speeds. I can feel the difference with it removed from the car even at 70 MPH.

 

IMO, the key to VX220 aero is a VERY low front splitter, however in my experience it needs to be 6 to 7 CM off the floor to operate, which makes it completely unfeasable for the road

I'm not sure how anyone would actually know... without seeing it on track and comparing it to other cars it's all based on your "feel" for the car. Can you every really explore the limits of the handling/grip on the road?

[Claws]

Given that the standard 175s work perfectly fine on the road...my money is on "no".

Testing it on track is the only real test you can do for optimum handling. On the road there are too many bumps and you will never get the rubber hot enough to realise the grip potential of the tyres you are using.

[sford]

While I applaud your efforts and all you have done to you car, I have to agree with Paul. The difference between my tyre temps (in a lowly NA) and the grip at Bruntingthorpe compared to sustained use at castle Combe was significant, even taking into account the ambient temperature difference of the two days.

 

Castle Combe would be a good place for you to try the car Nev, book one of the mid week days and see what it's like. Its got long straights and high speed bends that would allow you to test the aero properly. The last one I did was £155 and you barely come across another car with an open pit lane. It's not one of the action days where all sorts turn up and it's a smash fest. You can go and do 3 laps, come in and adjust and go back out. They stick to 10ish cars out at a time and it is very reasonable.

 

The speeds that you would do on the road are both irresponsible and not capable of testing the high level of modifications you have carried out. You took me out at a midlands meet one sunday prior to your body work modifications and the car was an absolute weapon then; I'm sure it is even more capable now. I always look forward to seeing your developments so please don't take this negatively. You're welcome to come and join next time I go, I have a couple of Elise owning friends and we have a good laid back approach to enjoying the track without getting drawn into racing one-another; rather just enjoying the cars and being able to use them closer to their limit in a safer environment.

Errmmmmm, Combe's noise limits.......

At an Anglesey National would have been easier.

My VSE and ITG came in at 97db, their limit is 100db. Depends how loud nipper is. Friend with a k series S2, larini cs and decat was 98db. Nipper may be a lot louder though.

 

Croft do 105db days and I'm sure there is someone there who would love to see Nipper flying round.

The last static test I did at Coombe registered 106.7 dB and the noise when it is on full chat at 8000 RPM is way way beyond that.

[Mopeytitan]

Could you not make some db reducers? Or due to make up for your exhaust tip would it not really be worth it?

[Nev]

Unfortuantely not, my exhaust tips are not deep enough. Also, the problem with dB reducers is they can affect the engine/map due to a considerable increase in back pressure, this isn't so bad with the OEM ECU as it self calibrates (I think), but with mine it is more "set in stone" (I think).

Oooof!  That is loud.  There are options, decat silencer, single tailpipe to reduce trumpet effect, resonator etc.  It all depends on how much time / effort / expense you want to go to in order to get on track

[Zoobeef]

Get yourself up to Blyton park, plenty of runoff and no proper noise limit.

I though tthat might b the case with the make up of your exhaust tips.

 

But as Matt says its only worth putting money and effort into getting it quieter if you plan to track it regularly enough to outweigh the cost, etc.

Yea, I'm not anti tracking the car, but it seems like the number of things to block you are considerable. The ease/simplicity of just going out spontaneously on an early morning weekend run on the road has a lot to be said for it IMO.

It applies even more to the road though. You won't get your car seized by the police for failing a noise test at a track. Fail one on the road and you risk a Section 61 for the first offence and then having the car seized if it happens again.

[siztenboots]

no speed limits on track
