Haha you guys crack me up, I put the car on the scales and all parts onto the cabin that haven't been fitted up yet. There's no oil or water and wiring loom so we took a good rough guess and added it onto the final reading...............................................................................................................................................................................................................................…...……........................................................1268kg

But wait it gets better, last track day we did we had a full tank we think.. Only did a few laps so there should be at least half a tank of fuel in there which we are gonna drain to see how much. That's 1268kg- say roughly 25kg(could be more) which brings us down to.........1243kg

But wait there's more...we may have a carbon tail shaft coming, don't really like these as they stuff up, well they did stuff up twice already on my mates r32 gtr but his exhaust was close to it and ours isn't. So if it arrives that's 9kg less I believe, bringing spare standard shafts regardless to the event.

But wait theres more......we may be putting in a lighter seat as mine weighs in at 9.5kg, borrowing a mates carbon seat and weighing it tonight and need to see if it fits on our rails too.

Our class allows us to be 1215 in a gtr32. Pretty close I reckon and I'm honestly wrapped, thats freak'n awesome for a fully caged car without chopping all the metal out. These guys have done such an awesome job, wait till next weekish, shits gettin good.

11th September Phillip island practice day. On Track events.

Hey guys, most likely gonna do this test day as we need it, if anyone wants to join us and drive their car I can get it for half price. It will cost $330 as opposed to 660 if you wanna share a garage with us, it is the best event as you get heaps of track time, more than any other track day you can do twice over. Private message me if you like but can't guarantee spots as they fill fast. For anyone else that is interested in coming to watch, please bring a lap timer as we need proof if we beat our old time, or if the car won't start.

On Track Events Private test days at Phillip Island Circuit has been put together to supply an affordable test day at circuit without overcrowding. $660.00 inc GST.

The days are run with a maximum of 12 cars on circuit at any one time giving series competitors between 7-8 Sessions per day. Shared pit garage included in price. If separate garage is required a cost of $100.00 will be requested on day.

We run 2 -3 sessions alternating between two Categories (Closed roof cars/Open wheelers inc Aussie race cars, Radicals, Wests etc). Event is ran under CAMS approved Top Car Regulations in including all medical, vehicle recovery and race control supplied.

Don't you have to run AO50's at WTAC?

Yes correct, we will use advan AO50's when were competing at wtac, we picked these hankooks up at a rippa deal. The advans are 2k a set and testing gets really expensive. I hear both tyres are pretty much on par. Anyone that has used both to compare, feel free to comment?

We haven't used r spec semis in years, so this is going to finally answer my own question, what's the lap time difference between slicks and semi slicks?

That's pretty amazing man. My GTSt is what people will call 'fully stripped' and it's 1250kg wet excluding fuel. Only thing carbon is the bonnet. Wonder what I'd get mine to with similar weight saving measures. you've gone to. Good work. That's what's needed to get up with the EVO's.

I reckon you could get under the 1200, your doors although already cut out are still heavy and could have 20kg maybe combined in them for replacement carbon or fibreglass, boot etc etc it all adds up. If you want to go extreme you can cut the whole ass end out, engine bay, strip the firewall to one layer but those costs in labour alone would be a small fortune. The evo's and wrx's are allowed a weight of 1054kg- worste case 1122kg, that's a massive 100-150ish kg difference. Last time we were out we weighed 1320kg so if we're around 1240ish then will be interesting to see what 80+kg difference will do.

You might be surprised. The doors are still featherweights even though they're steel. I don't think I could even save 3kg each. The outer skin is so thin. It's a very cost effective way of doing it. I want to cut the ass out and go with a fuel cell for 3 reasons. Better weight distribution, less weight overall and more room for a rear diffuser.

I guess the only way to tell is to weigh em up, but probably best to put your money else where on the car if there's only 6kg combined. We thought about cutting our ass out but after speaking to a mate that has done it he mentioned there was only about 4-5 kg, then you need a fuel cell, make up a brace which then only saved him about 2kg in the end, not sure about your standard tank but ours is pretty light from factory, if you cut all the rear out you most likely need new mounting points for your wing depending on your secure location too. I also checked the angle of the the rear diffuser which will eventually go on fits perfect under the standard tank which sits nice and low. And the cost to do with labour and fuel cell purchase all for a couple kilos wasn't to my liking but if your serious about weight as its addictive then go for it dude.

Yeah true. Part of the idea is a little subframe in the boot for wing mounting. With rules this year in open I'd have to drop my wing down. If I did I'd like to have the option on going back up for other events.

Yeah us too, might need extra wing mounts.

So after posting that comment that there was only about 4-5 kg in the boot savings....I reckon there's more, because today I decided to cut the rear parcel shelf out and the boot bulk head and weigh it up.

So I'm posting these pics and a vid which I hope works to prove to dean and Brett that I actually did something on the car finally without breaking it. Yes it's true, I'm no mechanic, and one day after wtac when they can be bothered reading this thread they will remember I actually did something right.

Damn it, video doesn't play I uploaded from iPhone. Anyhow myself and Pauly cut the rear shelf out and the bulkhead metal between the towers, total of 5kg, so I reckon if you completely cut your boot floor out you can get 5-10kg maybe, I'm not gonna cut it out as its gonna add more work to do and time is something we are short on but thought it would be nice to share. The photo between the shock towers was a before shot.

To save weight (by not having to seal off the boot, and we cut it out anyhow) and time and money, the surge tank was placed under the car for these reasons. I know its not the best location for weight but the other factors are more important so they come first. It will be covered to keep it protected from stones etc, and if we stack it, that's the least of my issues.... Cheers

Pauly pointing out the obvious.

    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
