Had a long chat with Martin (Martin500labbats) yesterday at the Beulieu Show, he had his Texaco RS500 touring car on display, this is one of the Ruddie Eggenberger built cars from Germany..........

Lots of differences between the way it's built compared to the Andy Rouse UK cars - BUT LOOK (pics):

1. Two fuel rails (as homolgated), the outer fuel rail has 4 x yellows and the loom connectors fitted - BUT no fuel line/fuel supply (i.e. dormant rail).

2. The inner fuel rail is made of 1" (25mm) box section and has 4 BOSCH 1000cc injectors fitted!!! This was back in 1986/7...........so how far advanced was Rudie's spec....no wonder they were hostile to Andy Rouse coming anywhere near their pit garage to have a look at the engine bay.

Will put up more pics in a while, including the HUGE Bosch water cooled ECU (about 40cm square amd 70 cm thick)........

 

I love them old touring cars! Am very jealous of Martin!

 

no vernier pulleys?

 

Doug, Martins posted about the injectors at least 3 times on here. Can't believe you have missed them all!

Love that car

Steve, no Verniers on this one either...

 

also ran air injectors doug.

 

Well spotted!

Maybe they used offset keys though Steve

Neil.

 

Steve, believe it or not verniers were not allowed......well thats what Martin said......BUT you can still time up the cams without verniers - no problem.

 

Certainly seems probable, they are bound to have had a way of adjusting it.

Obviously you can only make a couple of degrees difference on keys, but thats enough probably.



Fascinating looking car that, real piece of history, im jealous as hell

 

Apparently you can offset the place in the pulley or the camshaft where the woodruff key goes to do the cam timing. Gods knows why

 

Only if they allow the use of something like offset keys.

 

Lol, a few replys since i read the post and replied. Cant keep up with the pace of the site

 

No normally the pulley and the cam stay untouched and you just use a key with a step in it, well thats how i have done it in the past on engines ive built where i havent been able to use verniers for whatever reason.

 

A certain tuner on here (he builds proper big power engines) is quite happy to avoid verniers

If asked by the customer, he will time up the cams by REMOVING the keys.........therefore setting up the timing (on engine dyno) and then tightening up the nut to the new settings.........as long as the nut is properly tightened it is safe.

 

I'd sooner have the insurance of the key as well TBH, but its perfectly possible like that, thats how Zetecs work anyway IIRC, and lots of other engines for that matter, obviously they are designed that way from the outset though not just done as an afterthought.

All down to personal preference, but as you say the nut (well bolt actually, not that it matters!) tightened properly should hold it in place well enough, especially if its a race engine and hence only run for a few hours between rebuilds anyway.

 

i guess the std DV had to be used for homologation reasons too?

 

Oh i see,thats how you do it

 

I believe that that FIA deemed that Atmospheric ones were unnecessary due to an absense of schoolgirls at the track side to moisten anyway.

 

Huge Bosch water-cooled ECU.......... not a good pic:

 

 

pmsl, well its vented to atmo in the pics!

 

Yes but without the use of an orgasmanator polished alloy trumpet.

 

More processing power than early space missions is the scarey thing.
And less than the average modern phone!

 

It's also connected arse-about face!

Neil.

 

feckin PMSL

 

they work better like that because the boost is acting on a much larger area than normal to help the spring keep the valve closed

 

Silverstone 1987...........on left of pic Andy Rouse - um.........just walking past

 

Its MUCH better like that, I got 2 DV's for my car and main reason (barring the noise ) I dont wanna fit em is im worried that theyl leak a bit at full boost for that exact reason.

They all made backwards

 

Steve, you NEED to fit those DV's mate.
Your "Zero to Three" time is going to suffer massively if you dont, it could be increased several times over in fact, some vehicles have shown increases in time of up to 300% by removing the atmospheric DV!!!!

 

Back to the topic, and steering away from the Wolfman....................

Didn't some of the touring cars use a Zytek ECU?

 

yes mate

 

Sure did mate. Martins got a few, he even got a spare with his lastest white ANZ car that he stole, I mean that got very cheaply the git he was telling me about it at Combe. can't wait to see the Video that has been made as well and also watch the cars at ND. Should be awesome seeing them on track again after all these years.

The Zytec ECU are the ones where you can manually adjust the fuel and the ignition from knobs on the front as I remember.

As Chip said though these Ecus are pony now though, but well worth having if your car is a genuine piece of history like Martins are

 

Up for Doug, now that i have removed the crap off this thread

 

Is that Steve Sopers old car btw?

 

It's the Steve Soper/Pierre Dieudonne car.........as used for the European Touring Car Championship

 

what a great car!

if anyone ever says 'the RS500 touring cars'

i always seem to picture the Texaco ones in my head. lol

must be brillient to own a piece of history like that!

 

I love those cars, Here's a bit of info for you guys...My Merkur gauge surround is now in the Texaco car does that make me a silent owner LOL

 

here you go,
























my labatts car still has the zytec ecu fitted, and that works fine,

but as i am racing the ANZ car we removed the zytec system and fitted the tryed and trust good old L8 with pectal baby board, as we now use air to air injectors for the T4,

also removed as it was not needed was the rouse mechanical fuel pump,
that now sits on the spares shelf,

new loom, was needed anyway as the original was bit second hand looking, so apart from the ecu ect, its basically how rouse would have had it,

i fitted a pectal moniter to replace the exaust senser gauge, so i can moniter lots of info on the same unit,
