I had a ball yesterday... pitty I was having issues all damn day.

I blew up a turbotech boost controller

I blew off one hose and destroyed 2 others!

I was just running out of brakes after 2 hot laps... Yellow stuff pads and dba slotted rotors= fail track day (r33 on my r32). The 4 year old federal 595's were only good for 2 hot laps before they started to heat up too much.

I did dip into the 63's though at 1 bar of boost ha ha ha... (tuned to 1.5bar- high 29Xrwkw)

Next day, I'll check my tyre pressures too :-) there was 4 psi difference between the fronts cold- ha ah ha. And better brakes!!!

Cheers

When it was running right, it sounded and moved allright.. From a ratio/turbo size/engine set up point of view, it was pretty good.

Really needs swaybars and more camber too.

Same old story, brakes and tyres let me down.

She went allright for a simple street car.

from what i've read qfm pads at waaaaaaaaaaaay better than bendix pads

i'll be getting some hpx pads for the stagea

the ar1m's are good hill climb style pads - full bite from the get go

but they have comp7's (i think) that are a proper track pad which would be good for those of you that only track your cars

they are pretty cheap too, hpx's are about $70-90 (i forget) and the ar1m's are about $140 i think

I think I read that the HPX's aren't being sold by people in preference for a slightly more expensive but much better pad? I had a good look into QFM AR1M's when Jack recommended them ages ago, and I couldn't find anything but absolutely positive results, especially for the price. Very tempted to try them out myself later on :) This is the email I got from GSL Rally Sport ([email protected]) when I was enquiring about them for my R33 earlier on in the year.

A1RM to suit your car are $119 per set front or rear. Shipping is free when you order front and rear together, so all up for the whole car would be $238 delivered.

A1RM is the pad we recommend for a mix of both street and track work.

Easiest way to order is credit card over the phone, 1300 884 836, or else swing me your delivery address (preferably a work or business address!!) and contact number and I can fire you through an invoice with direct deposit details.

I'll be looking into some ducting (brakes, oil cooler, rad and intercooler) and some better race day pads for the next outing.

Also, for everyone with an RB with a stock sump, there are a couple of brake ponts/corners where oil pressure dips!!! I might have another look into accusumps.

Anyone want to sponser me a couple sets of semi's? ha ha ha

i can hook people up with used race tyres for realistic prices. 235x45x17 and 265x35?x18

have a look at bens build thread if you want to learn what barsky can do to your oil system. we have datalogged race cars and found oil pressure drops to zero under heavy braking. whist under braking the engine isnt under load so it wont destroy a bearing straight up but we have found after a season it will ruin a bearing or 2.

Yeah, comming down the hill into the left before the back straight- the guage bottoms out!!!

Affordable race tyres.... that's what I like to hear!

So for noobs like me, what sort of precautions/modifications should be taken into consideration to be better prepared for such instances?

I have EBC green stuffs in my R32 with 8 piston calipers/356mm rotors and on sunday they were starting to smell really hot after about 5-6 laps of using them fairly hard, i really shouldve put my hawke pads back in worship.gif only took them out due to being daily driven, and they squeal alot closedeyes.gif

Since i put the G4 brakes on my R32 i would see the oil pressure drop to 0 (std gauge) and the oil light come on under hard braking even with street tires, but before i went to baskerville yesterday, i took Damo's advice and overfilled my oil to the hump on the dipstick (about 900ml above the FULL level on the stick) and this completely stopped it, even braking hard from 175K's with semis on the front it didnt run dry once, so i would strongly recommend this.

I wasn't doing a lot of heavy braking but around the bends my oil pressure dipped a little. Do share the research you've done sump wise as I'd be interested too :)

For my Cefiro Track car (RB20DET) i will be doing a common modification of gating the sump, which will completely eliminate oil pickup issues, along with an external oil drain.

Once you get your drainage issue sorted you will be a lot better off as your oil will return to the sump where it should bethumbsup.gif

RB's are quite good for not losing their oil supply when cornering as the sump is quite narrow and the sides are vertical, it has no where to go, but braking is the big killer.

I really don't think the external drain does much at all. You need to put in restrictors to stop excess oil getting into the head in the first place.

If you guys are having braking problems at Baskerville, you're going to need to do a lot of sotring before you head to Symmons. Baskerville isn't that hard on brakes.

True this,

I had a chat with Brad from Boost Automotive and he offered some very good advice.

My VCT wasn't enabled so that was dumping a whole lot of oil into the cam covers, enabling that should help the cause.

I'm pretty sure I've got some Tomei restricters in atm, not sure of size.

Standard N1 oil pressure would be above 100psi so I might drop that down to 65-70 with a new relief valve spring

My tiny baby NA Cam covers proboally arn't helping, some GTR ones with mines style baffles will help too.

oil restrictors in block, enlarged oil returns..

if motor is already assembled you should be looking into larger capacity sumps, with or without gating.

decent breathing system of the head. as savman suggests the oil drain from head work more so as a vent, so it can be done other ways without removing engine.

a quick simple way i have seen mentioned is a hose from the dip stick to the catch can... unltimately its only a quick fix if you only track some times. It's about equalizing pressure...

here is a link to a thread, its all been covered over and over again. good read

Yeah i'll definitely need my Hawke pads for symmons i think thumbsup.gif

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
