Full e85 barrell stuff real world for reference if it helps as Ive pushed 2 x sets injectors to limit Above mentioned Bosch 1480cc run on 4 bar base to the apparent 1650cc on rb2.7 yielded 912hp / 684 kw at 92% duty on hub dyno ID1700's - RB 2.8 ...1015hp / 760 kw at 87% duty - hubber dyno + shown off data on track my opinion IF you change injectors just go bigger than you think you need the modern/ good larger ones run just fine if tuned properly even if way bigger than required even on streeters

Id like to race in the US i think alot of those track would suit me For the s15? Youd be stuck between club sprint and the new Open Am wouldnt you depending on how much interior you have left in

thanks for heads up on actuators - will sort something as back up or solution as yes dont need that have enough trouble but no doubt some addition of something to spares boxes is required yes have a clue about WTAC but nothing has been officially put out yet so will wait to see exact details Pro class is, has been and will become a draw card for lap records and one off builds for show and thats about it I think - be interesting to see how open they make it Pro am is the old Pro in reality Open class will be split into 2 with slicks and 050's with no doubt slight variances in allowable drivers and changes in aero Clubsprint + apparently a true street class They have to and are refreshing it all and bringing things up to current standards and need to 100% adhere to rules because whether people like it or not / or say it or not - for alot of competitors it is sheep stations and has been for a while when Im getting told I was illegal because i cut my rear bumper too high and yet others where in the grey areas of legality with everything from engines, suspension, ride heights and more serious influences it actually got quite out of control and heated this year so as much as I may be impacted by some of the changes and prob spit the dummy when I have to spend money changing things I think its a good thing for all

Recently did the Perth Festival of Speed - and basically what we thought might be an average event turned out to be absolutely awesome they bought Mad Mike and Xtreme over and was good to see Perth get, support and produce something so good - 24,000 people in two days It was nice to have it close to home for once yet have my whole crew there to run the car properly Xtreme got the tin top laps record with 51.57 I hadnt done a hot lap on the home track for 20 months and finally everything clicked and dropped 4 secs off PB and did a 53.29 which is 3rd fastest tin top ever around that track. only 1.3 tenths behind 2nd so should eat that up soon... can I get Xtremes time - its not out of the question Alll the blaa blaa's in the world but if I can replicate even close to that situation on other tracks will be able to make an impact We got asked to do the hill climb to put on a show which in reality is just using some chicanes and the short track at barbs but good fun... launch control was put in and won the Pro class in that also. Car needs some attention after being on it around Australia for last few months moreso the carbon underbody work and just a run through and clean up everything else seems to have held up good enough. Would like ,to take some weight out but that requires alot of effort 😁 Also waiting on new rules for WTAC and have some decisions to be made there and prob some minor modifications to suit pending class changes. Will see... Divided on whether to go hard for one more year or chill out re: events this coming year prob more on the go hard and see if I can get improvements in times. If I didnt have so travel so far it would be less of an issue but I do so hmmm... Also because build thread - gone to flappy paddles and a gearing change with a drop gear. It was becoming apparent that there were situations where I really needed to be hanging onto the wheel with both hands yet had to change gears and was getting a little sketchy and / or I just didnt change gears and delt with it and also 5th gear at 10,000 rpm is 290 kmph so I havent been using 6th as did 282 at WTAC and 274 in Perth drop gear will change to 6th being 300 at 10,000 rpm should also get a touch more acceleration speed

as above find out what you want to do with it but extremely general Id get a more modern car with tech in it - add suspension, brakes and tyres - drive it if needs cooling add that - drive it maintain and have fun

Yeah agree but probem is you cant find any! Not many made in the first place and now like hens teeth

correct Ive moved to a r33 oem ball joint - they are actually thicker than alot of the after market and similar

there are probably many ways to do it for my bosch motorsport abs we used a r33 gtst abs front knuckle and modified the rear knuckle to allow sensor to sit and read understand time, effort and $$ but reading from anywhere else you get diff chatter etc where you lose 30% ish in signal clarity compared to the above

Thanks... yeop I think anyone thats had to compete or travel more than the usual home track situation gets it and prob even those that havent yet had to do it ... its just harder and costs more fullstop As one goes through this, prob like yourself, you gain and appreciation of effort - almost regardless of the result - but the result can add to it on top This year I did enjoy it alot more even though it was harder ...which is actually good!

Thanks mate yeop be good ! Understand the kid thing for sure lucky mines a bit older and I can bring him over etc he gets treated like a rockstar 😁 go the RB yeop wont be doing this forever prob so why not 100% everyones always been good but going back this year was different and more interaction and def more support Def thought about changing uprights etc waiting for @Komdotkomto sort out whats needed for those and do the r & d haha but yeah hard thing for gtst nothing direct fit as all made for GTR which is slightly diff but moving to the r35 gtr bearing will be big improvement - its just budget allocation as its a $10K to $30K exercise dependent on how mild or wild you go and seems something always comes up - ontop of the crazy travel / racing

OK WTAC '24 adventures - dont know if anyone wants to hear it past whats been put out already but hey I'll put some of it out anyway and try give some insight Summary : end result - 6th open class and 1.31.1 lap How'd we get that Following the above after Aus Time Attack at Winton and driving the car up to Sydney to store the rb2.8 went in so got to fly over to Sydney the Monday before the event The car was with Greg at Sydney Composites workshop - we got straight to work that arvo changing out the front wheel bearings as they flog out allll the time. A new bonnet was being made and my goodness its nice ! also new bigger canards were put on as I was the first one to trial the new canards and after testing from others bigger basically proved to be better rather than my initial cut down version. We also did ride height changes and setup was there till 1am Wed morning but got it all done A big focus this year was to get me some seat time on SMP - laps for me = good so has an extra prac Wed morning to roll around so up at 6am to track Basically 2 quick sessions and 3 'hot laps' we quickly worked out that the custom red / golds MCA's I had in werent valved strong enough to hold up all the new aero at these speeds, we suspected at Winton but were hoping... but alas nope. Also the tyres I had on from Winton were gone and just down right dangerous haha So... some appropriately valved MCA golds were sources from Canberra and driven up straight to the track for me to borrow and retro fitted with my current stuff and some better used tyres put on from Xtreme. Got into the arvo where I had to take more prac spot so took it - we got 2 x goes at a lap but the setup was wrong and was porposing like crazy so aborted each one but we got it sorted correctly after but didnt get to go out again WTAC official prac Thurs Did 3 sessions of 1 lap each time no power - suspension better few tweeks here and there and got to get a little bit of a groove back all seemed OK We found the car getting back to some understeer because we still had the old rear suspension in and it couldnt handle the aero load but had no options so had to work around it ... it ended up scraping the rear diffuser that sits quite away off the ground that how much it was ! WTAC - Competition day 1 Morning Session - usually the best - wound it up had a crack was good but safe and not the max from a push p.o.v 1.31.6 The wind then picked up as did temp went out just for a lap on no power for second session did a solid 1.33 totally sat out the last session as no point due to track conditions WTAC - Competition day 2 Morning session - full send ! - ran it hard down the front straight as I got to T1 turn in car faulted and switched off - tried to do another lap after resetting tyre pressures and fuel but was not working properly and got blocked and then had red flag anyway haha - bad Long story short - the balancer had gone and as well took the DBW with it Organized chaos ensued - between my team - Dahtones and Herman and just about everyone else we got everything needed and a new 1500 ATI put on - luckily thee was a Bosch motorsport stand in trader ally and they let us take the DBW they had on display to put on my car ! legends So at this point we've only done 1 real lap , missed the good session in the morning missed session 2 Pit walk was upon us and is always so busy but great and met @soviet_merlin and others we also try to get as many kids in the car for fun and photos as possible + meet people Session 3 - last one - wind was up, track was horrible didn't matter had to go - launched it as good a I could. We changed setup to leave the car in 5th gear into front straight so I didnt have to change down and worked well just held it flat max powas and max rpm - 282 kmph and 217kph around T1 (this has to improve alot )was up 1.2 secs into T8 despite mistakes and as previously said tyres just started going to mush - I couldnt get it around T8 properly lost most of my time picked more up with last 3 corners ended up 5.5 tenths up on previous good lap for new PB but missed out on top 5 by 6 tenths Still not my best lap I shouldve had it to make top 5 but didnt... thats racing A positive takeaway from an effing tough go at it this year - netting only 2 x hotlaps is both my 1.31 laps combined optimally gave a 1.285 - now I know I'll never be perfect but with a 2.6 sec difference - that means its there it just comes down to consistency to bring that down into an achievable 1.29ish Our best endeavors to have good seat time and a well sorted car illuded us this year but still got it done as best we could Good mate made me take a pit pic in front of the car which I look at now and is good as you just dont know I might not be back, or I might ! And then after watching the wild Top 5 shoot out you get to pack up starting at 9pm so pack it all up properly for long trip home We had a sleep and then yeop ... a near 4 day drive back to Perth. Look I dont actually mind the drive - its not great but its not horrible - but the toll it takes on you after or before competition isnt optimal and neither is the time it takes to do - maybe another option but they are few and expensive I tell you what im basically an international and would be ALOT easier to compete at WTAC if I lived anyway but W.A 😆 All in all hard work, solid result on paper but even if I was still 6th I would've like to at least be in the 1.30s and as close as I was and maybe due to circumstance it still says a 1.31 - which isnt sh*t just not the best .... the W.A crew that comes with me is awesome, im appreciative of getting to work with some of the best on top of that with Brad and some help from the pro drivers, Xtreme and others So back home back to it - full set of MCA golds going in now which was on the cards anyway and a new 'proper' race radiator to keep it cooler See what comes up next to race at or in ... that I dont know

Walking through WTAC pits is a mine field fullstop 😆

Hey! Thanks for that it great to meet you sorry wasnt for long was hetic Hope you enjoyed WTAC! Yeah we upped the rev limit in 5th gear and just wound that out rather than a shorter change to 6th and back to 5th again around T1 and wow it was screaming its little RB tatas off 😄 That arvo session I had to go out! I hadnt had a proper run since the morning session on Friday so was my only chance to go full send Theres a reason the top teams dont go out because the track was absolutely junk! I had to have a crack and my 1.31.1 prob wouldve been a low 1.30 in a morning session in fact I was up 1.2 sec on my 1.31.6 coming into T8 even then but the tyres literally went to mush Still managed a PB ad 6th in Open class not horrible for a guy that gets about 10 laps a year on SMP and only booked 3 hot laps The car is very good now But wow it was a hetic WTAC might do a run down just got home yesterday from 4 day drive back to Perth

thanks mate. yeop thats me ....they turned my tired ramblings into something decent which was nice 😁 I shouldve just said refer to SAU for said history ... its pretty much alot on here haha

Youd think.. dunno All these engines run Tomie B pro poncams This becomes above my pay grade and rely on others and get I quote "your decision making powers have been revoked" 😅

medium amateur ?? VCT rather have than not and they NEO heads anyway... agree shouldnt be down there in revs agree but one does stuff up at times and does help 😁

who'd have thought and some compression 🤔

in reality the new engine was a swap alot because it was brand new vs 3 years old and the other one needing a refresh after wtac anyway but... the 2.8 is obvious capacity etc and will do current power more easily and add some responsiveness not that that was really lacking the limiting factor with all this atm is injectors (ID1700s at 4 bar base) and turbo (precision 6780) literally being maxed out at bang on 1000hp as thats what the system was designed to do, so to go more need injectors, turbo and maybe even intercooler but i know a guy that like his power and will see how this all unfolds it is a rwd drive on an 050 tyre though and i am just a complete amateur so among other things the ability to drive it becomes a consideration also

Its was definitely cold 🥶 us w.a people dont take too well to it We even took to doing 2 warm up laps to get to the tyre temp we wanted Update for those that want a read A week before Aus Time Attack in Vic did a prac day got few laps then carbon bonnet decided to fold on itself whether it too much air under the lip, a pin failure or just pin not cliped in it happened... got fab guy to plate it 2mm ally each side and wrapped it. 15kg heaver but solid and mad max ready to race Greg from Sydney Comp having a new carbon bonnet ready for us for WTAC Off to Aus Time Attack at Winton for first time another 3.5 day all day drive Did pretty decent with 4th in Open class and 6th outright with 1.24 flat Way more in it I was just too inconsistent to extract a quicker time without more track time and by the time I got decent enough to drive a good lap the tyres where cooked Still OK Drove the car straight up to Sydney and put in storage ready for WTAC flew home to Perth Blaaa blaaa the opportunity came to replace the billet RB2.7 with a brand new RB2.8 billet nitto wide journal complete engine a round about deal was done and Dahtones put it in this week and Brads tuning it on Thurs The RB2.7 would be avaiable for purchase from Racetech is anyone wants it such a killa engine !! Apart from that its back into storage till the new bonnet gets put on and I rock back to Sydney in 6 weeks on the Monday before WTAC to prep the car get some practice in and send it and see what happens! Update over ... for now 😁

For real life ! 😅 Hows that guy at 1.25 min in thinks he's still a drifter !!! Geez it was so slippery most of the time

Msg away 😆 obviously I didnt get specific details about what you wanted etc but know the Emtrons can do most of the same as M150 and little cheaper Otherwise M150 yeah does absolutely everything but you do pay extra to add on this and update that ie: logging normal vs pro package etc traction control - well helps hold my car 😄 obviously combined with other tuning factors built in blaa blaa we work it off wheel speed sensors for Bosch ABS and have setup for various slip percentage selectable via keypad

awesome work mate ! Emtron for ECU I recon (dependant on tuner) but link is pretty good can you buy expander box ?

👌 awesome work mate. Time to see it on the track. Gonna be good

no probs I got 1 maybe 2 coming with me atm ... yeop hopefully advance in times and all that - fingers crossed - just looking to push and get better - tis all we can do its have a go right

Hey Yeah ill be there ! Hussling hard now to get seat time and make car all good see if can get some early track time over east 🤞 Itd be really nice to have some luck 😁
