Top RB20 Club... do you have over 260rwkw?

[Cubes]

I doubt you will get anywhere near 200rwkw with a stock 10yr old pump.

Mine decided it had enough after 10+years of use and 155rwkw.

Yeah that's kinda my thinking on it. Thanks Cubes.

The bigger the dump/exhaust, the less backpressure and more power potential

Ok, so back to the nothing on low revs with RB20 thing, wouldnt back pressure help off boost? Or does having the turbo there do what the exaust would normaly do on an N/A car?

Also have any of you lot had problems with 550cc injectors??? (mate with 1g) has major cruise tune issues, and it would seem its because the injectors are far too big, the hit maybe 40% dudy cycle on 25psi on a freezing nite, and its not running lean at all.

Kind of along the question I had... and goes with the GTR injector topic above. Would 440cc's be to big for the stock computer to handle with some sort of fuel controller (already have an S-AFC)? I think I'm sold on the PFC idea finally vs going with microtech like I was thinking before... but with the turbo I have now GTR injectors would be a nice safety factor to have once I get the turbo rebuilt and pushing more than .4bar.

My experience has been that you can get enough fuel out of it with an SAFC (or similar). It's tight and you have to compromise on the ignition timing, but that's normal.

Well i think i killed another RB20 today at Winton:(

This time it wasnt the poor RB20s fault though...34degree day so wound the boost back to 10psi, but that was never going to stop the bonne lining from catching fire and starting an under bonnet BBQ:(

Im all for sharing the good and the bad news:thumbsup:

... so note to ppl driving there cars hard at the track, consider removing the bonnet lining...especially if its 12 years old and starting to perish, also no doubt has a degree of oil etc from fumes etc etc....

The old RB20 was going top guns up until that point, even with only 10psi:)

[Cubes]

Did you change all your fuel line hoses??

When I had the RB20 out I noticed all the hoses (little ones around the fuel rail and under the fuel filter) had big nasty looking cracks in them. I really can't believe they weren't leaking. Maybe they were.

Any damage to paint work and the like Roy?

Damn.. I really feel for you dude..

[Roy]

Nah, definitely not leaking fuel lines.

You can tell by the blistered paint on the bonnet that the fire was above the turbo....so that crappy lining has dropped and came in contact with the turbo or it got so hot that it just caught alight:confused:

I think the guards are ok, but the bonnet has seen better days, and some engine bay wiring needs replacing. It seems the loom has been damaged as everything is dead, and the starter doesnt kick over etc etc

Could have been much worse, the track safety guys were champions, they were onto it straight away:thumbsup:

[Cubes]

So the car was hammering then just died?

Pulled over and saw smoke?

[Bl4cK32]

sorry to hear Roy

[Roy]

Car was going good, then i smelt something as i drive with the heater on high, so some fumes started coming into the cabin, shut the car down straight away, then as i coasted around smoke started to pour out of the bonnet, so pulled over and the fire crew came and put out the the fire in my engine bay plus the grass fire i started...woops:)

Looked way tough:thumbsup: Forget graphics, real flames and smoke look way cooler

[Cubes]

haha.

So about that rb25 head I saw you enquiring about in the for sale section the other week.

If the fire has done any damage to the motor (doubt it) then I guess its time for you to head out and grab yourself an rb25de, drop a thicker head gasket in it and enjoy the same amount of power on around 5psi less boost at a lower rpm

[Roy]

LOL...i like how you think.

Basically ill wait til my sunstroke passes then ill have a look at it. I wanted to slowly build up an engine on the side, say $750-1000 /month, but this changes things...

Thanks to Geoff too for being good enough to let me store the car in his garage until i suss out what im doing...and to Jack for the tow:thumbsup:

And fark the Vic Track Gods who have cursed my car since crossing the border, 3-4 years of abuse in NSW without a hiccup, 6 months in Vic and drama after drama...LOL, should have known this was on the cards when i drove down to start the new job. Got a flat, then the space saver went flat, 18 hours to get from Syd to Vic:(

It all good though, got a VB in my new stubbie holder, and who knows what Santa may have for me...ive been good this year:)

[dangerous_daveo]

No good Roy, good too see your keeping happy minded about it. Cause yeah, thats some funny stuff up there! You need to get like a drift flame, thats not a drift flame, but a track flame.... if ya get my drift.

So yeah two things. 1st, Santa dont exist man, sorry to say, but he aint getting you nothing.

And yeah, Victorian air, its no good. Come to Sunny Qld, its tops!

And so we are keeping on topic, if the RB20 lives! It it the greatest motor in the world!!!

[Roy]

RB20 POWAH!!!!!!!!!!!!

[dangerous_daveo]

Ahhhh! SNOW!

[Roy]

Looks more like pigeon sh1t:)

[Sydneykid]

Ouch, bad luck Roy, which black cat did you run over while driving under a ladder on Friday the 13th? Tip, wash the white stuff off real fast, it makes a mess of all sorts of plastic and painted things. I think you need a GTR bonnet and grill, might even find a silver one that doesn't need painting.

Now I know why I like low/rear mount turbos:cheers:

:werd:

Thing is i knew better. I didnt drive the car at a few Syd track days because of the shielding issue. But a few ppl/workshops kept telling me i was paranoid, so all the fibreglass wrap and alloy sheet sit under my bed with thefcatch can and painted rocker covers, ready to go on when i took my holidays....oh well ill be back on my soap box on this issue:(

Back to my original school of thought, you are crazy do drive with a high mount without a lot of shielding...if ppl try to tell you different, and show you a bunch of cars with bare manifolds / housings etc etc, do not listen, it CAN happen, and wiull happen. They have been lucky rater then me unlucky that this sort of thing happens:(

[Chris32]

Geez mate, very sorry to hear.

If you need any wiring, I have my spare motor at home with most of the wiring for injector harness etc, its yours if you need it no probs

Bad Luck mate, they say bad luck comes in three's so hopefully thats all for now

Regards, Chris

P.S - dump pipe flange has been made, being done after chrissie
