Well they say Lakeside is the highest average speed of any track in Australia. But I know the locals say the same thing about PI... so to compare i just went and found the outright IPRA lap records for both tracks (IPRA was just the easiest for me to find this data):

Lakeside (2.41km) Wayne Wakefield Mazda RX3 25/10/1998 0:57.4500

Phillip Is (4.448km) ROHAN AMBROSE MAZDA RX7 12/09/1999 1.46.0362

Unbelievably, both lap records work out to be 151.01kph average speed - equal to 2 decimal places!

The Supra is basically the way I bought it from Japan. Its got Jap Teins, Jasma exhaust and pod filter. It has the small brakes but they do a pretty good job - don't fade or go long in 5 or 6 laps of Lakeside.

No other suspension mods apart from the Teins, but I spent a fair bit of time messing around with ride heights to find a nice balance. And we got as much camber and castor out of the standard adjustment facilities as possible. Camber maxed out at 2 degrees on the right, but we got 2.5 on the left. Castor is 3.5 degrees. Zero toe. I haven't messed with the rear end alignment yet.

Tyres are Kumho Ecsta XS (KU36) 245/40 & 275/35R18. They're not a real semi slick with a treadwear rating of 180, more of an in-between tyre like the Toyo R1-R but they have a treadwear of 140.

Engine is standard boost, standard intercooler. I did what they call the 'TTC mod' which involves re-routing a couple of boost lines that control the operation of the vavle to the second turbo to make it run in parellel rather than sequential. Gives you a fair bit more mid-range, but obviously nothing extra up top. It was hopeless on the track in sequential!

It really needs to be driven hard to get those times though. There isn't anything left in it - not with me at the wheel anyway. And I have alot of experience at Lakeside, which is a massive advantage there. I'm a bit surprised to only be 4 seconds off the IPRA lap record in a near standard road car in full street trim and street tyres! :wacko:

I can't vouch for the accuraccy of the tacho in an 18 year old car, but it's definately moving. Consider I'm entering the straight at a fair clip in fourth gear and pulling fifth about 30 yards before the tower, seems pretty accurate to me? Lakeside is quick you know :P

Was yours the black R32/33? in Harry's group? Some quickies in that group, black RX7 of course, black Silvia, white Silouette. Good to watch you blokes in action :P

I knew Lakeside is quick and the entry on to the straight is quick...lol from watchin Touring car races :) Just surprised as my car is only a tad quicker down the straight at PI and its all down hill, copme onto the straight similarily in top of 4th into 5th so at about 180km/h...and i have substantially more power?!?!

So it seems that my extra grunt is only good for another 5-10km/h :blink:

the turn onto the straight at Lakeside isn't that fast. about 140kph I'd say. I don't think Ben has that much speed on me down the straight either - I'm hitting 214 by the braking area after the kink, and seem to pull away in a straight line. Maybe its got a lower diff ratio?

Gearing could be different. But mine is pretty damn short anyway. Just keep an eye on if you were run 4th gear to 7,000rpm what speed it equates to? The gearing of the GTSt (tyre diam permitting) is that if you have the std ECU then you hit the speed limit and the rev limit in 4th gear pretty damn close together. So top of 4th gear is typically around 180km/h at 7,500rpm. LOL, i use every one of those revs as the turbo needs it :D

You can see the gearing is pretty short as i am almost running out of revs in 5th gear and i am only about 235km/h :rant:

Oh and Ben, this was my car with the Bilsteins pre Teins. It has settled down a lot with regards to pitching under brakes and lift off oversteer, all the nasty stuff :(

Roy, you need a decent seat dude, look at that move around! lol I can't wait to get down to PI, apparently there's a two dayer there run by Stokel next month that sounds like fun, I won't make it though :rant:

Your car sounds awesome, I don't rev past seven as it just runs out of puff with the std turbo. As I said can't wait to get your Teins in it, I reckon it'll be a vast improvement :D

Love to tell you more about speeds, but the speedo dunt work :[

Yeh, i have a seat but i dont leave it in when i am doing lots of street driving. Before PI it was a rush to get tune leaned on for more power and new tyres fitted, so seat was left in the bedroom...i miss it when its not in the car.

Yeh, since i am not tracking my car at present i welcome the R32 brotherhood borrow some parts to help us all suss out what works and where we can improve our respective steeds :( Bumpy Lakeside will be a real test for them and you are a more experienced driver then me so any thoughts would probably be more accurate then mine.

LOL, but i would love to see an in car vid to see how the car is handlling/driving with them :)

I think my speed calculations might be a bit optimistic too. I found my copy of July Motor magazine yesterday with a PCOTY test at Lakeside. The Porsche GT2 hit a top of 215kph and ran 58.5 according to the performance box data. They come with Michelin semi slicks and it was driven by Warren Luff I think. The Supra can't be doing the same speed as that Porsche. That's what you get for using speed per 1000rpm data from the internet I suppose...

  • 3 weeks later...
way to go Danny Mischok! a driver with at least 10 years experience in IPRA circuit racing even manages to look like a total fkwit in a field of noobs in their road cars! good work mate!

looks like I'll be back in the Supra instead of the Datto this weekend...

HI Harry

It's amazing what you find when you google your name!

You whould probably get your facts straight before shooting your mouth off as the crap that went on with that knob Doug Chappel was from his own inexperience as most of us that actually race and not potter around at sprints always give it a bit of a suirt coming out of the pits IN THE RAIN to see how much tractions available and unlike most my thing comes on like a train at 4000rpm and like bounce off the limiter at 10k in the dry let alone the wet but Doug or John wouldn't know that as they've never had anything with any poke! Then when he carried on like a spoilt 5 year old because I didn't see the black flag, is because it was raining and mine like every other IP car doesn't have a heater so the car was fogging in places and when go down the straight with the Motec saying hte front wheels are doing 178kph and the back wheels doing 204kph with a G sensor reading strange, you know maybe I wasn't going in a dead straight line and I was a little busy! as even when we raced there for real they had two black flags, 1 at the start line up at the tower and another coming out of the carousel as you never saw the one on the start line let alone one being held by an inexperienced knob on the fence!

As far as the noise of the thing it has been tested numerous times here in Qld and interstate by the NSW EPA! at has never read more than 92.6db at 30mt's as per Aust Standard and even here at Mt Cotton on their on and the Redlands Shire Councils regularly calibrated computerised monitoring gear the car never goes past 92db with it normally around 91.6db. So to find out that I was being judged on a rather suspect hand held piece of junk what hasn't ever been properly calibrated and the controllers not being able to decide between themselves whether it was 102.5 or 106.5db does not distress me that much but what does worry me is the amount of bullshit going between all parties that control Lakeside is that you guys better make the most of the opportunity you have now as it could all go pear shaped as the council had unrealistic goals when even brand new road cars are failing the noise limits with ADR complianced exhausts.

And yes I am welcome back with the car but they want me to rework the exhaust but they will not accept that it isn't the exhaust which is popping their Dick Smith-Tandy Radio Shack sound meters but instead the induction noise

If you have any questions or disagreements with anything I've said ring me as I don't bite and I tend not to shoot my mouth off too much in public

Danny

Ps If your under the impression that you were going to beat me around there I'd get you credit card out as my old single cam engine did 60.8's on old Yokohama A008R tyre and not even the RS's! and Gerry got down to 58.29 sec with his 168RWHP YB Cosworth powered Escort and mine makes ALOT more than that and has had a lot more development and before you start going on about the track IT WAS ALWAYS THAT BUMPY and the patches on the corners they aere always there in some form so you can't blame that for you only doing high 2's

well I did beat you out there, by about 11 or 12 seconds that day!!! So if you're under the impression you're going to beat me out there, you better sharpen up a bit mate! And unlike you, I only got 1 clear lap after I passed the STi that was holding me up., hadn't driven the Datsun since the AHC in 2007, and had never driven it in the wet. So much for you not pottering around at Sprints eh?

high 2s? my standard Supra road car ran 1:01.3 last time on street tyres (not semi slicks) on the track as it is in 2008. Not realy worth comparing to what you (or whoever Gerry is) claim to have done over 7 years ago. We all saw what you were capable of the other week - 1:20-odd!

Your car was easily the loudest car there on the day, and was never going to be under the required db limit. It doesn't matter whether the noise is coming from the exhaust or the induction, there's a noise limit and your car was way in excess of it. And you ignored black flags lap after lap. They were hanging out way over the pit wall with a giant black flag... its you responsibility to look out for flags at the flag points. I managed to see all the flags just fine and I don't have any demisting or even working wipers in the Datsun!

My Supra only has a cat and a Jasma cannon on the back and it easily passes the noise tests out there. My Datsun only have a res and straight through muffler and again easily passes. So I call bullsh1t on the brand new road cars failing the noise tests at Lakeside.

don't it make ya proud?

Still making :banana: new friends i see :P

yeah, much like you with this comment. I've known Danny for years Vince, whoever you are... what's your problem anyway? Never met you or had any dealings with you. All I can remember is you taking exception to me posting to let other SAU people know about the Lakeside Sprint Series when it started, and you felt you had to rush to Paul's defence for some reason just because he also ran 1 day out there??? That ain't me making new friends, that's all you bud.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
