:-D this is BP - we only give you a kicking if you upset all the natives ...

Dunk, they look odd mate ... how about a remake in carbon :)
Dum spiro, spero

I caught one yesterday on a kerb and grazed it - at is is they are cheap and cheerful and no problem for that (the splitter has grounded lots of time already). Carbon would not work better and would break.

Exactly the response i expected... ah well :?

I wasnt knocking the suspension brakes improvements at all, not one little bit infact.

I was asking as to why all the aero? These are the bits i can see making dick all difference if youre not 100% as fast as you can go already.

Surely the suspension,brakes, power all need fine tuning first before you go down this route. At this rate youre changing so many things at once how on earth can you tell which bit is actually making the difference to your times out there?

And yes i realise just how expensive the TA is which is exactly why im not in it. Not to mention the fact that i dont have the driving talent to be out there with a chance of winning. In my opinion if you cant win, dont play. But fair game to everyone out there that is enjoying it.

My comments were regarding all the aero, nothing else, so dont get your panties in a twist.


Back to polishing my car then :)

What other response could there have been ? ... ooo sorry you are right, I will take them all off and revert the car back to standard, put my old engine back in cos I never got every last ounce of speed out of that, take the cage out cos I dont need that on the road....

Get with the times Frayz, look around the paddock at TA and you will see lots of cars. ALL OF THEM would be quicker with Lewis Hamilton driving them. Does that stop anyone modifying or improving them?

I edited my post with reasoning as i knew you would want an explanation.

These have already been done.

Nothing will have changed aero-wise from the last time I went on track to tomorrow night (are you coming out on track for that?) apart from the small additions to the splitter. Hardly an avalanche of mods.

Does everyone have to stand a chance of winning to compete ? - you are missing the point of competition. Competition is a development ground both for the car and the driver. This is my first year in TA and I dont pretend to be a driving god but I know I am a better driver now because of it and the car is way better set up because of it.

It would bore everyone even more rigid if I mention on here about tweaking suspension geometries, arb's, ride heights, roll axis's, springs, damper settings, tyre pressures or mapping changes. It doesnt mean that these are being ignored - far from it. But I will not be making huge changes in one go without verifying that it is going in the right direction first. That is what development and testing involves.

As I say, you are welcome to your opinion.

No panties here :D

Duncan, I for one would like to know all the boring details (yes i know a i'm a sad git) especially geometry and mapping ;) , and i am sure a few oither TA competitors on BP would like to know what your setups are too
( a bit of industrial espionage) so i look at it more as not wanting to give away your secrets rather than anything else, which is fair play and i would do the same!! :D

Some of these TA cars though don't seem to have a huge amount of visible aero aids (quite smooth some of them with no sticky out bits) and seem to handle pretty damn good looking at their lap times so i would have said that was a geometry/suspension/hidden aero aids setup thing as well as driver ability no doubt.

Equally i have noted that some of these high power TA cars come with more visible aero aids than an F22 Raptor but don't seem to get round anywhere near as quick although look very blingy!!

Whether these aids work or not is one thing but i have to say yours look pretty damn lethal either way. 'Death Race 2000' comes to mind :D
Buggers cancelled my op just a couple of days before it was due. Inconsiderate barstewards!! :rant:

for my limtied 2 penneth if they help dunc drive quicker either due to actual improvements to the set-up that suit dunc's driving style or give dunc a placebo effect which gives greater confidence and therefore potentially more pace on the track then theyve done there job. My limited undertanding on these things is set-up is also a personal thing and depends on who is driving the car. granted talent means that many drivers can drive any car quickly but I think most will agree if the car is set-up how they like it they will be quicker. So if they help dunc fair play.

I am not sure anyone sees me or my car as a threat :(

Mapping wise - it is there or therabouts 8)

I truly believe living with the car and driving it enables a better ultimate map. It feels somehow more mine now if that makes more sense.

Some stats for you Francis:
Max load: 4.7 (equiv to 9.4 on the 32 bit ecu like yours) This has been roughly proportional to torque.
Max g/sec: 409. This has been roughly proportional to whp.
Hits 2 bar at 3k if I want it too
Tails down to 1.6(ish) at 6500 rpm
Injector duty 83%

I have spent some time sorting out minor niggles such as wiring a switch into the fuel pump to stop it pumping when ignition is on. The pump was hard wired into the ignition by zen as they could not find a suitable feed that cut it if engine was not going like the OE pump. This was a nightmare for flashing as the pump sounds like it is going to self destruct if it is pumping nothing. So now I have a nice switch that i can flick off to kill pumping. This could also act for safety in the case of an accident I think (but that wasnt the main reason for it).

Also sorting out hoses/clips and other solutions to the main niggle and hoping to fully test these tomorrow.

Suspension and power are both being worked on.

Can't you fit a relay to run the second pump? Triggered from the OE pump feed it'd be safer than a switch that may or may not be remembered in the unfortunate event of a serious off.
