Hi Jim,

I find these results amazing, 20awkw is a substantial increase!

I have booked my final tune with crd for next week...I will post my results here for everyones perusal.

Regards,

Marko.

Hey Guys,

Here is dyno sheet of a R33 GTR with a new engine we built with R34 N1 turbochargers with before and after of 98 and 100 octane shell fuel.

Car is used for circuit only.

ive had my safc tuned for 98 octane.. if i use this extreme stuff would i REALLY need a retune?

Only if you rev the engine out, or value your pistons' life spans.

The fact that higher RON level means you can run more timing isn't as important for the retune, but the fact that its oxygenated means your engine will run lean comparable to your 98RON tune is why your current setup may not be good for the engine.

If you've got it tuned close to the edge on 0% ethanol fuel, the E5 Optimax Extreme might push it to a point where you get detonation.

This is big I actually calculated 41 extra four wkw for extra 2 octane points. Must have had more timing and maybe more boost added to do this?

We did same on S15 yesterday and made almost 20rwkw with a bit more boost and timing.

There is a question mark with the Ethanol in it effecting injector seals as well as early model injector design and electrolysis. But hey I am going to use it and guess it should be ok or they would not release it, or are we all test pilots?

well, i had a sip of it yesterday and it tastes no where near as good as bp ultimate. true.

It certainly looks like a good option for race use. Much cheaper than the options from elf etc.

I've filled half a tank yesty.... just a question tho... I have a stock ecu.. how do i reset it... and.. do i need to?

Reset does jack....

I had mine on the dyno ~3years ago, did a few little tests - pod vs stock airbox, ecu reset. All showed a zero increase in power anywhere in the rpm.

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
