Fuel testing results

--------------------------------------------------------------------------------

Well after much anticipation and discussion and great effort the stage was set for the battle of the race fuels. William from Autosalon magazine arrived by 9:30am while Ben was putting the finishing touches on his in drum walbro custom makeshift fuel system for the tests.

Started out and my in tank stock pump decided to play up which was okay as we had the walbro anyway so on with the tests. The my lower drivers side cooler pipe kept blowing off, tried constant tension clamps massive T bolt clamp torqued right up no go in the end Andrew had to weld some lips onto the pipes and all was sorted.

Car was making 250ish on pump fuel which is pretty normal so we tried the Martini again altered the timing and only 255 wtf. continued the tests and all the same around that 250 mark. After several scans of previous charts we new something was really wrong. Boost isnt holding still and power is not there. Time to do a compression test, all plugs out and we got an average of 132 excpet for cylinder 6 good old number 6 who decided it liked around 75. Ben did a cylinder leak down test and confirmed that the rings are in fact to blame. So looks like everything got a little too hot and cooked number 6 cylinder.

Conclusion -

Test was inconclusive due to car problem and I spent around 2.5k to find out my number 6 cylinder is rooted, hence why I am sitting down at the moment drinking a bottle of Moet and Chandon and generally feeling down about the whole caper. I had Autosalon there and everything and no results to show for the effort put in apart from a very large repair bill. Oh well such is life and had to happen sooner or later just wished it was later about 6 months later then new engine would have been done.

Once the new engine is built I will rerun the test and see whats what.

Jp is going to buy some of the fuel and test it in the slotcar next week so some results will be forthwith

Its not over yet!!!!!!!!!!!!

This all in your 300 Jason?

Hope everything is ok mate.

When you say Martini - what type of fuel/octane rating?

It was supposed to be a comparison of the top rated and most expensive unleaded race fuels money can buy.

I got some ELF Turbo max at $8.20 per litre, Martini Super turbo 1400 (formerly M110) and Sunoco GT Plus.

So we had a Euro fuel and Aussie fuel and the American stuff.

But then we found the comp problem aaarrrrr.

Will sort the engine in no time and will rerun it so all will not be lost

Cheers

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
