He literally only did setup laps in the morning on damp track and low power - but still went closeish 😅 hmmm put it this way i went well over 1 but under 2 secs quicker on no more power than previously run, plenty more on tap and old tyres Only did 11 laps - got told to pack it up we're good

Usual photo dump from me: Full hotside and rewire done - I dont get excited about much but the wiring is top notch The office is functional and comfy - getting to be alot to remember and think about though sometimes 😆 Fuel system wasnt going to do what we wanted to updated with new surge intank with some walbros and super mega flow fuel filter + wiring and sensors Finally got it home after few months gave it a wash even in the rain ha Fitted up the new Syd Comp aero few other bits got some wrap fixed up and nearly ready Dyno time was on with the team all went relatively well made good powas - was injector restricted even pushing them to max but did the numbers needed was back to my house for full suspension check, look over, change and other things. Finally got a test day in Didnt take us long to get it working very well - pretty good result in such a short period of time, surprised me, but if you look at the million hours of work that went into the lead up it should be expected but not always the case. Car is just good. Full stop We came a way with a list of things to change, fix and ammend but nothing major its just work to be done in the next 3 weeks then we are off

awesome effort and results well done goes alright the old girl !

Youre a special individual sir 😆

I know alot of people like that 😄 Im the other way - car is good Im junk so I have to work harder Which Pro am car is it ? The reality of the combo reaching its potential first time out is extremely unlikely but hopefully have a decent experience and hit out and you never know Yeop he will be over here in just over two weeks for a few days to get us in the working window very quickly then will be heading things up with the rest of my guys as obviously he has a few other cars too

It massive to get over there, compete at a decent level and back cant be a big fish in a little pond in w.a forever im ok with it being the other way its a challenge nice 28's is extremely fast. we think we got a decent idea what my car can do... the problem being the driver and the lack of SMSP track time. But thats part of the game!

Thanks mate! yes its only 7 odd weeks away and my cars not even ready yet 🙄 😅 typical.. See you there!

Surprisingly not - or not that I have experienced to the extent its been detrimental - overall the car is the most compliant its ever been to be honest In saying that I dont go near high ripples and only take on very low one, bumps on slower corners circa < 100 kmph seems to go fine - relative to a more circuit only orientated suspension setup with no aero I cant say because its been a while now so my perspection might be skewed We have a track down south at Collie that that is more technical and slower speed corners it handles it relatively well but has a very bumpy back straight I struggle there at speed it skips sideways half a lane at times but not unbarable but I dont think my car is optimal for that particular track Also I might add tyres and tyre pressures play a big part in all this - part of doing all this was moving from a 295/30 to a 295/35 profile tyre its a big difference in height of sidewall - the difference in compliance and extra 'squish' of the tyre aids in both mechanical grip and compliance/ handling with the stiffer/ limited travel suspension and management of total actual car travel under compression over and above what the suspension does... but then you also have to take that into account to keep it off the ground also

interesting to see how it goes.. I may have documented it early in my build thread with only a rear Origin wing (which lets face it does nothing but add drag) I initially upped the fronts first like you to 13kg left the rear the same - too much understeer still upped the spring rate from either 6 or 7 to 8kg from one event to another was only 2 weeks apart - changed literally nothing else in the car picked up 0.75 sec a lap consistently on a 60 sec lap as the balance of car just got better Re: engine bay 😆 In WTAC open class terms at least I still have a relative OEM front end most are tube framed - im getting to see why over and above just weight recently ha

while we're rolling little updates Car is plumbed up with new hotside New full car wiring, motec system with keypad etc 90% done / nearly complete - added EGTs along the way this thing has more sensors than the NASA space station upgraded gear position sensor as couldnt control auto blip good enough Found Id bent the front subframe - so got new one plus braced + new front LCA/ castor combo - this was within 4 events of installing and using ABS after it being fine for years so assume its extra braking load Had to increase the fuel system now going with intake surge with 1 x lift and 3 x pumps walbro New aero being put on right now plus a million other things might even get to drive this thing soon 🙄😅 Id say it should turn a tyre when we turn up the wick but spose the whole point is to not too haha how all this is going to end up I dont know Im just a guy having a crack at going fast

Id say its because as you mentioned 1) for tarmac 2) because the gold MCA's have a different builder, parts and methodology (ie: valving) around them to all the others produced with the MCA brand 3) because we are trying to keep mine in a max 50mm suspension travel range 🤪

Proper aero and aero suspension is very specific and different to conventional setups: Going back to the start of my car build: I think MCA reds come out valved too lightly and are valved linearly and with the recommended spring rates are too soft - so people including myself up the spring rates and loose some control trying to balance out the softer valving MCA Reds out the box I think were 10 or 11 front and 6 or 7 kg rear - was too soft me me even with no aero - even at that for a normal car it was too soft for me I went to 13kg front and 8kg rear pretty quick As I added Topstage rear wing, then ally front splitter then sideskirts etc ended up at the same valving but 16kg front with dampners on hard 3/4 and 10 kg rear at dampners hard 3/4 - it didnt handle great/ chewed tyres etc Then I got my first proper carbon front splitter with good downforce - with the above setup I plowed it into the ground and destroyed it within 2 laps Cue the people that actually know what they are talking about: You cant keep Aero cars up with spring rates - you cant put enough spring in them to keep them up in the first place and then if you can it'll handle like a brick anyway: Without giving IP away: My cars valving is now progressive - soft initially moving to harder with compression My spring rates are back to the range I started with / a normal car would be recommended The car sits on a combination of hard packers and progressive poly bump stops after a certain amount of suspension travel that only allows the car to go so low - which what keeps it off the ground The suspension travel - droop etc is all limited to a smaller specific range by spring perch/ bump stops and various other things Essentially trying to get the best of both worlds making it compliant / softer in slow non aero corners for mechanical grip and progressively harder to sit on full hard bump stops to keep it off the ground

Yeah mate. Right now murray has revalved etc the mca reds similar too / essentially mca gold without remote canisters But have been through different incarnations of mca reds through the course of the journey. But mostly was playing spring rates over recommended early on

I had vct removed with big cams on my previous track rb25 build as tuner didnt like it and said it was running in higher rpm so didnt need If running it on track hard at higher rpm mostly avg joe like me prob wont know / feel much diff unless on really tight track and then you just go down a gear but I had sequential But if still manual and not track vct extremely still beneficial Rb26s dont have vct and seem to still go good Rather have it than not though but not a complete deal breaker depending

Nice. Thats what I was going to get but at the time he couldnt get cores and said didnt know when he vould get me one

https://shop.pwr.com.au/55mm-2-pass-crossflow-radiator-nissan-skyline-r32 55mm Crossflow is what I got went from 42mm (i think) typical koyo koyo was fine but started to struggle on my setup as I pushed it harder - above cooler change has done the job well since no probs

Koyo still decent do most jobs - $700 Recently wen PWR crossflow circa $1100 found big difference in cooling

Didnt get to use the new artec/ garrett combo those invloved with the car preferred to use what has been tried and proven combo for them to get 'x' result For power, response/ powerband, boost control and emap and be running this higher in the rev range than previously

The car is getting advanced at a rapidly slow pace but getting there Now moved to new new hotside to a 6 boob T4 divided flange, with Precision 6780 with 1.15 rear divided T4 flange and 60mm gate and as always - nothing is easy because racecar 🙄

No stock engine is reliable up there but it can be on the edge of reliable if your not belting on the track 24/7 and you have the oil situation sorted You dont need cams for anything really but it makes it more efficient and effective But yes on the edge at that power level where they may or may not be advantageous vs response etc 350rwkw ish is perfect and very fast car for street and even track if you set it up for that As someone who put a good 5 holes in the side of stock bottom end blocks its usually either the rods/ rod bolts that go or the bearings due to insufficient oil system And then after all this your going to have to have your tuna manage your torque because your going to want to mash your foot on the loud pedal and it has to not knock the tyres off to go fast fwd not nowhere

Ran these on my track car for years. Good construction etc as you stated and few little quirks to getting everything to fit but are good and solid. One things is I found they chewed tyres because of the ackerman when cornering, this experience is track only related

Yeop sure did. Awesome sauce glad he had some left! You get level 2 or 3 logging?

I dont actually know yet, as undefined as it is, I think its when the combination of time, effort and $ vs its ability to fulfil my personal drive / challenge to go fast or get better and the want to build and maintain what I consider to be a pretty cool car...tips on the negative decent crash and Im done dont like it that much to rebuild 😅 na more of Tassie Mode Agree though yeah about neo head spec with vct Yes I have alot of his setup and IP in mine and now his old Rb2.7 billet. He has developed a proven package that just works and actually just gives a sh*t and wants people to go fast Along with the guys running my car over here now who are awesome its a solid team
