Bills 33 Gtst Streeter/track Car

[admS15]

Not yet, will try it. I have a spare one but there is a hissing sound i can hear from the pcv area and hiss stops and idle lowers when pcv is blocked. A boost leak test didn't show up anything. Will do some hunting around tomorrow.

Good luck

[admS15]

I feel like im gonna need it. Im wondering, because it's a vacuum leak and not a boost leak if it will be an issue under boost and if it will cause grief if ignored.

Car looks good. 

Good choice going with the Pro 200; it's a great seat. I had it in my R33 a while ago and it is very comfy for a race seat and holds you in nicely. 

[admS15]

Yeah the seat is good, only complaint is the gym routine to get in and out of it. Im using a small pillow to reduce the depth my butt has to lower itself into. Otherwise perfectly comfortable and easy to live with. More comfy than the S3 R33 GTR seat it replaced.

[admS15]

AAC was my high idle issue back in the day of 33 ownership, super common. 

Cleaned it recently? 

 

10 points Dan. Replaced it with a freshly clean spare and problem solved. The hissing was obviously a by product of the valve not working. Happily idling at 800rpm now with a stable afr.

Went to Sandown today, was a glorious day for it. Unfortunately no PB, got within .3 of a second. The day got off to a very slow start, like 10 30 am slow. This has become a commom theme lately. Stopped for lunch at 1pm and i had only done 1 session. Unbelievable, only 45 cars, 4 groups and just managed to get 4 sessions in as they combined the last session with slow and fast cars. Not a smooth day, thats for sure. 

On to the positive stuff, the new seat was fantastic and i didn't have to worry about getting thrown around or my knee hitting my door card, the splitter didn't snap or go flying off. It seemed to do what it's meant to and the car felt like it had a fair bit more front grip, i got a bit too confident and pushed a bit too much until i found the limit, had a bit of an off, thankfully the car and splitter survived. The fist session showed promise with a 1.24.1 just .5 off my pb with unset tyre pressures and heavy fuel load, the second session yielded a 1.23.9, that was as good as it got. The splitter definitely made a difference but the tyres aren't in good enough shape to provide better times.

This was also the first time at Sandown with the 4.3 diff, it worked a treat, all the slow corners where taken in 3rd gear and turn 1 in 4th for most of the day. Im not sure if it was quicker or slower, i think if the corner entry is spot on with enough speed, 4th works out better, will have to review race chrono data.

Got a bit greedy here

 Will try and get some race chrono data up later as its on my spare phone still in the car.

Cheers.

[admS15]

Reviewing the race chrono data, i could have theoretically done a 1:23.27 with the best sectors put together.  It also seems that using 4th gear was a little slower. I was getting to a top speed of 140 before braking and when using 3rd up to 145. With more practice it may or may not work out. I dont think there is much in it and ill just decide next time im at Sandown what I'll do.

Race chrono data. The 1:23.9 lap is recorded as 1:24.13 on RC. Dont really know what was more accurate as the official timing wasn't done with dorians. Im assuming stop watches. Lol.

Overall, im happy with the times for yesterday considering age of the tyres and condition of the track, there was kitty litter debris all over the place. There was also a Saturday track day and obviously quite a few cars had off track excursions.

When I saw it start heading to wards the wall I feared the worst for you lol 

Good job to stay off the armco

Yep, lucky i was able to react quick enough while the front wheels where still on asphalt and get it to go the other way. There was a sigh of relief as i was staring straight at the armco that i would have been getting the repair bill for. Arse end couldn't have missed by much either, judging by the rear tyre marks on the grass that can be seen when the car is facing backwards.

Some good driving there!

I would have sent it into the armco with my derp style driving

It's called luck.

Entered Phillip island track day this Sunday.

 

 

Thought id continue on with my tight arse bunnings/ebay aero package and Frankensteined this on the back. Bought the wing 2nd hand off ebay for $100 and made the brackets out of scrap steel from work. I did everything on them except the welding which was left to a work mate.

 

The bootlid with gtr base was bought on gumtree about 6 months for $50. I was until recently using it with a modified evo 7 wing blade that i bought for $20 but for another 100 i thought id try this one. Backyard bee r style.

 

 

Should compliment the bunnings spec splitter perfectly. Will find out on Sunday if it does anything useful other than create traction due to the extra 15kg this weighs over the carbon boot lid.

Looks good

[admS15]

PI track day done and dusted. Was a good day out, nice weather and a smoothly run day by the wrx club. The ebay aero seemed to do something, i managed to improve my PB by 1.66 secs on well used tyres. The car did feel more settled around the high speed bends and the extra drag didnt seem to effect top speed either. Actually managed to go 1 km/h faster than ever before with a top of 243.  Since i added extra weight with the boot and wing, i removed the passenger seat to bring it back to the usual weight. Car ran good all day, only needed to adust tyre pressure and add fuel.

Nice work, maybe top speed was better, despite drag, because your corner exit speed was higher due to better grip?

Possibly or the wing was that crappy it didn't do anything and i just drove better. I was braking later into turn 1, felt like the wing helped under brakes, speaking of, the last session proved to be too much for the rear rotors and they fatigue cracked. Lucky i have a spare new set at home.

Im already thinking about a v2 wing that bolts on to the chassis on the sides of the boot lid. That way i can retain the carbon boot lid and not add too much weight. Also thinking a decently designed carbon blade profile that will create proper down force. Just got to work out a budget way to do it, lol.

2nd best lap

 

 

 

Next time, the aim will be 49's. I know the car has it in it, just a question of if i can make it do it.

[admS15]

Not much has been happening with this, just daily driving and enjoying it. Has been running fairly sweet. Being an August built car, she's just turned 22, so i got her some birthday treats to show my appreciation.

Fresh engine, gearbox and diff oil as well as fresh fuel and oil filter. Will do plugs on the weekend, all in preparation for some track action. If the weather is good, i'm hoping to get to Phillip island on the 9/9 and then the SAU Sandown day on the 29th.

Tyres are looking pretty 2nd hand but im determined to get as much use as i can out of them. Happy just to get out there and have some fun. I'll assess what they look like after PI and if need be, may get a new set.
