lol that is so damn true! don't forget, a street car is still standard even with 30k spent on engine and suspension

There is an age old saying Duncan:

The fastest cars are in the car park.

Most people with a half decent track car will stare at their feet & start mumbling when asked what it has on it.

Most people with a half decent road car will bang on about it for hours and hours, or post up some huge thread in an internet forum. :D

wakefield slows down in the arvo? I hadn't noticed. My 4 fastest laps last time were my 4 last laps....

Maybe it's different in summer?

I find the same thing. I always go quicker in the afternoon. Partly the fact that i have burnt 30-40L of fuel and mostly the fact i have done a few laps and got my eye in. I wish i got enough track time that i can go out to a track day and punch out the best 4 laps on the day in the morning session :D

The track is faster in the morning at pretty much every track that I visit, but you have to be ready to take advantage of it. That means the car AND the driver. If the car has a tank fulll of fuel, the set up isn't right and the driver is still learning the track then they are missing out on the fastest track time of the day. The exceptions are when it rains in the morning, which is like everytime I have been to Wakefield lately and when it is a temporary circuit and it is faster as the rubber gets down.

Yeh, yeh, yeh. But we are talking about me the hack who is lucky to get 16 laps of a race track every 3 months. :down: Its all good in theory, but odds are most ppl will go quicker later in the day. We are not all race machanics/engineers who can have the car all set up to go. Obviuously those in the know or with workshop backing hold a large advantage.

Hell at Wakefield i could never be bothered to take spare fuel or go back into town so i always filled tha car up and just drove the place. Never attended a sprint round there so didnt really care too mcuh about lap times. But these days i have the spare 20L drums of fuel and only run with 20L in the tank.

I welcome anyone who wants to set up my car, hire the trak for the day before to get he car and driver dialled in. A big bouncer to keep me away from the pub the night before and then pay for a second set of tyres for the sprint the next day :( Even things like heat cycling tyres. At track days i often waste morning sessions just cycling the tyres as i am after the best were possible from them and i cant really do it on teh streets, not around the city where i live :(

I tend to just change tyres, check pressures and drive these days.

Other than maybe a minor adjustment of the pressure after a session or 2 i don't change anything as the car is at the limit of adjustment for the bits that are on it atm.

A new front sway bar is on the list. Need a 27mm to balance out the 24mm rear as it's just a bit too taily.

Just because we don't live in the ideal world, doesn't mean that we can't dream about it.

Really?

Ah well, with me thats what I have noticed...but then again I am a n00b :D

I remember Mark and Russ saying something similar about wakie getting slower in the arvo's also?

meh - it slows down for me ok!?!? hahahaha (thats my excuse!!)

but just wondering what OP GP is like also :(

....and back on topic..hahaha

That is another thing Duncan. The mid week open days that i used to go to were dusty, dirty as hell. Unless the track has has some cars sweep the track on a Saturday with Prac/Quali then i think the track woudl be slower in the morning. God knows poor old dust bowl Goulbourn would have lots of garbage on the track mid week in a morning session?!?!?!?!

depends on a lot of varibles so i dont think a general rule applies. At my home track im generally faster earlier but away its the later sessions that reap the fast times. The weather plays a role too, in summer generally the faster times are early and in winter its later.

it was quite weird at Tsukuba circuit, all the fast guys were out and aiming for their fastest lap in the first or second session, the m speed guys reckon that track loses about a second or so a lap around lmidday on.

but like has been said many variables, i think the tyres they were running wouldnt like running later.

myself personally, i tend to go best in about the middle of day before i start pushing to hard and getting untidy! :wave:

There you go. That is why you play A Grade and i am stuck in the shit kicker grades with all the sodomties, because i am at my best at the pub the night after the affair :happy:

Ah yes Roy. The best lap times are either hand timed or run at the bar. :D

    • If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.
    • Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...
    • Right, but I thought the problem has been for a while now that even if you know manifold pressure + throttle position you still have non-linearity and aliasing issues vs actual engine load? One way I can see things simplifying is going DBW, then all air going into the engine is represented by the throttle position. As opposed to a random bimetallic strip vaguely linked to engine temperature opening and closing a shutter or some random power steering air valve suddenly allowing a bunch of bypass air. But the same throttle position/RPM at ~atmospheric MAP in different gears is not guaranteed to be same engine load? Honestly, ITBs are of such dubious value IMO. I don't know why these things are hyped up so much. The main benefit as far as I can tell is you reduce the likelihood of cross-cylinder EGR scavenging with significant cam overlap at idle. I would absolutely run speed density and be done with it if not for this fairly esoteric control problem.
    • Hah dont worry, my adult brain has this conversation every single day. Dont waste your money, invest more of it into shares, pay down the mortgage. Then the bedtime insta doom scrolling begins and after being bombarded with gtr's my mind is set: im definitely getting one! I have the current model mx5 as the weekender, but i just miss my boost and literally like your username, the sututu's that come with it. I remember with my 2nd supra, as it had twins and vvti, they used to spool real early, like 1,500rpm so you could just be a spooly boy all day long. Some people say they get over it after a while, not me tho.
