btw, in some later sections I was getting close to just a slight lift at the kink and flat out under the bridge and over the crest into Hungry. if that doesnt make you feel alive I dont know what will.

Quite a few one end drive road cars go flat out through the kink at over 200kph, R35 should be what 20kph faster. Something to aim for.

  • 3 weeks later...

lakeside today:

59.72 beat my semi-slick PB by just 0.15. Was driving like an old mole out there though. These new tyres have alot more than that in them. 6 months away from a circuit has taken the edge off a bit, and I never really felt comfortable in the car today. Will have to go back again soon to get back up to speed I think.

yeah I have been going through there at 225kph with a dab of the brakes flat out I estimate would be around 235kph or so, on the 3-4 day old slicks it was starting to move around a bit which wasnt a comfortable feeling at that speed.

new slicks and some aero and 245 is the goal!

what tyres and size Harry?

Got the new Federal FZ201 semi slick. 235/45 & 255/40 R17. Wider rear changed the balance of the car again. I should have learnt by now, but will make some changes before the next Lakeside Open Sprint in a couple of weeks.

I just entered the luxo barge Aristo in the Street Sprints on Sunday, just for laughs. It might go OK - its basically a 4 door Supra, but with a slushbox... I think the biggest challenge will be remaining in the nice comfy leather seat.

now for some sounds of silence... my daily driver Aristo at Lakeside.

WARNING: this footage may distress some viewers. Particularly Evo owners

Session 2: chasing 6spd TT Supra and passing Evo 10

Session 3: chasing Porsche and Evo 7-9 (all look the same to me)

Stock boost, run turbos in parellel instead of sequential, factory option Bilstein suspension, stock brakes - need new front rotors now. Warped them in the 1st session and you can see the vibration through the car under brakes! Has trans cooler and FMIC. Compliance cat, 3" mid pipe to twin 2.5" and stock rear mufflers. 62.6 best lap. vMax 193.4kph thanks to the HKS SLD :)

hehe, got a bit excited...

bolted the wheels from the 180SX on, so it was on the Federal FZ201's.

The thing actaully handled very well with similar cornering speeds and the same lateral G as the 180SX. Would be alot easier to drive it that hard with a decent seat though.

The way the Aristo rode the bumps I'm thinking about softening the 180SX up a bit... again...

How did the auto handle the day Harry?

Ive always been wary of taking the Soarer out to the track because of that

Actually how did the car pull up?

As you probably know the Soarer and Aristo/Supra are basically the same, just the motors and number of doors differ

I've got a big transmission cooler on it. Just the largest Davies Craig one from Supercheap. They're about $130 and take half an hour to install. Temps on the IN hose were just under 70deg and OUT hose was under 50deg after each run. The auto never made any complaints on the track.

Engine temps were getting up around 100deg towards the end of the session, which is within normal operating range, and came straight down as soon as you back off. No problem there. Its still got the standard hydraulic engine fan.

Standard brakes, pads and fluid were fine apart from the old (and probably a bit thin) rotors warping in the first session. Its pretty common on OEM Toyota rotors from my experience. The JZA80 Supra I had with exactly the same brakes did the same thing. Changed to aftermarket discs and no problem.

Whack a trans cooler on the soarer and have some fun. If its in good mechanical order, it should be fine.

hmmm... graphed speed and lateral G from the 180 on Thursday and Aristo yesterday:

(lateral G x50 to get it to show up on the graph, so 50 is 1G. Peak for both cars is 1.2G

It wasn't the fastest lap int he 180SX - the iPhone didn't want to stay on the windscreen inthe 180, so I've only got data from the 1st session. This lap was a 60.5.

The automatic Aristo looses out in accelleration, but it looks like it was at least a match for the 180 in Eastern Loop and the last turn, if not a touch faster... Caught the 180 a bit under the bridge too. I suspect I lifted on that lap in the 180, or it got a bit sideways and scrubbed the speed off.

Aristo felt much easier to drive through Carousell, under the bridge and through the kink. Carousell's double apexer, the Aristo just goes where you want it to, no fuss at all. The 180 is always puts up a fight to get it back into the second apex. In the fast corners under the bridge and the kink, the 180 is pretty nervous on the bumps. Aristo walked over them with no fuss at all. Might be interesting with a bit more boost in the Aristo and maybe without the heavy electric seats! hehe

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
