Ledge's 240Z Track car

[charleszed]

Hi Ledge,

 

Great car!

sorry to hear about the engine troubles.

 

i was wondering where you got that front strut brace for your z

i have been looking for one like that for a while.

looking forward to the next stage of the car.

HI Charles

It is for a series 3 rx7 if my memory is correct. I got from

jap wrecker for $50. you need to modify the bracket but easy as

 

Regards

What happened to the engine Paul? I didn't look close enough but have you seam welded your shell or has the cage stiffened it up enough? Also wondered what fuel you were running and what the benefits are of going to E85. However I would imagine that you would need to modify your fuel system/corrosion proof it to combat the effects of the ethanol correct? Did you also extend your frame rails to stiffen it up. Cheers and hope to see it next year.

Hi Brabham

Number 6 rod decided it wanted some freedom. Have not pulled it out yet so don't know what caused this.

My oil pressure and other data logs don't show any obvious issues.

 

Yea the shell has been stitched up. The cage is full on and has plenty of attachment points.

The fuel system is setup and good for E85. But it is a pain for me to get it so I haven't changed yet.

The new engine when done will require E85 or Custom blend.

 

I hope to be there next year. On the way over I was only ever go there once, But as I didn't get the time on the track

I wanted I will definitely be back. Just depends how long the engine takes. The budget is what will make it take long time not the builder.

 

Cheers

Paul

You should look at a road trip before next year wtac thing, and combine say another event, on the way there or back.

A mob called FOSC do events at Eastern Ck, but check which layout they will use.

Or pick up on an ARDC Sprints meeting,

Combine that with say a Wakefoeld or a Winton l sprints event.

 

Surprising the number of entrants who have either never, or, only ladt years, have run at EC.

A lot of $$ layout for little track time, very hard to "learn" it properly.

Gives you a distinct advantage over the rest of the $200,000 "race" cars, that get finished two hours before the wtac event starts!

[Ledge]

Problem for me is running my own business finding the time to be away for over a week is hard.

I would love to spend more time on the track that's for sure. Will hopefully be back there

next year bigger and stronger so I can do a decent amount of laps.

 

Cheers

For anyone who hasn't seen the footage already

 

[260DET]

Great video, aren't you supposed to go flat through turn 1 though?

[Brabham]

Great video, aren't you supposed to go flat through turn 1 though?

 

Not in a tin top at EC, only in an open wheeler

[Ledge]

Great video, aren't you supposed to go flat through turn 1 though?

 

I wish. Maybe after ive done more than 10 laps there

[260DET]

Apparently some were at the recent Time Attack, no point in dragging all that aero around unless it earns it's keep. Apparently T1 is pretty intimidating and quite a few get it wrong so obviously it ain't easy.

[Ledge]

Some not so nice pics

[thriller]

Oh no, that's an expensive few pics

 

Would have been a pretty sour feeling drive back home to Adelaide !

[Ledge]

Yep bottom end is stuffed. Looks like the head is ok though.

fingers crossed

 

had better trips home from motorsport thats for sure

[260DET]

Nasty, very nasty. Looks like a lubrication failure.

[ZT-R]

Im on motor number 5 so don't feel bad. If that happened to you on dry sump I have no hope at all...

Hi Bud,

got any more pics of the main bearing girdle, just after removal?

and did you find any key pieces of the piston skirts, from around the small end? indicating any failure in skirt or does it appear rod only?

do your logs show any ign timing retardation prior to? and/or afr's issues prior?

already it looks like your cradle was a 'passenger' after the failure, check out the harmonic marks its left on cap-face on #6 bearing (between 5&6)

looks like the back end of your bearing girdle was a 'tuning fork'.......

Bad news, and expensive none the less.

 

Still appreciate the incar footage you still manage to provide, despite a day best left untold!!

[260DET]

The reason why I suggested a lubrication failure was because of obvious big end overheating and it's common with a lube failure to lock a bearing or two which then starts a chain of destruction which usually involves con rods. But a bit of a guess just going on pics of course. Any relevant data?

[Ledge]

HI Chaps

Yeah its a crap situation.

Culmination of  few issues.

They are all getting solved so we will move on.

Oil related for sure tho

 

Cheers

Paul

[Gordo]

That's a bummer. So it's a bigger job than you would have liked.

[Brabham]

Will you do a 30/26 for your next engine Paul or is it not worth it? Awesome sounding car though before the troubles.

[Ledge]

Gordo, yeah its shagged mate. If im lucky it will just need new short motor.

 

Brabham, 30 is not the right thing for my car.  Going billet 28 stroker

 

Sir Peter Mc has got he job

 

 

Cheers

Paul

[Gordo]

If Peters got the job your in good hands. You Know it's going to be bigger and better.

[charleszed]

Billet 2.8 stroker wwooohh

that is going to be lethal!!!

cant wait to see it alive again.

[Brabham]

Where does the block come from Paul, is it based on an RD28? Looking forward to seeing it take shape, will there be another jump in the power figures for this one?

 

Cheers
