I used your old fuel pump as a pickup pump in my tank Abo bob. It's working a treat ;). I will do a writeup on the meth kit as soon as I get some concrete results and I have been running it for a few weeks.

I had to rewrite an eprom to suit after the meth kit was fitted as the AFR's were to rich running a mix of 50/50. Before fitting the meth kit I was making 154RWKW with 10psi and bugger all timing(as i had no intercooler and i didn't want to risk pinging) and after fitting it I am running 14psi with 10+ deg more timing and making 204RWKW. I am really supprised at the power level as it's a stock rb25 turbo. But the dyno operator said it was to do with the massively increased timing and higher octane.

BTW there is no sign of knock at all.

I am really pushing the envelope and may drop the timing back and reduce the boost a little in the colder weather as my AFM is reading 4.0V at WOT over 7000RPM... injector duty cycle is also getting into the mid 80's.

I am injecting using a 2.75US gallon hago oil burner nozzle @ 110psi. I am in the process of setting up an intake temp probe and some other bits. But I am really happy with the performance...

Cool.

Sound like the afm and injectors still have room. Do you have an adjustable reg? Also can't you clamp the AFM signal or just ignore the fact that's it's maxed out with your tune? Mine maxes out all the time but doesn't matter even at 255rwkw. The other thing you could do is increase the cross-sectional diameter with a new pipe while keeping the same element and tune to suit. I've got some instructions somewhere that explains how it is done.

I'm really interested in your water/meth and will wait for your final results.

      He obviously had his reason for flipping you off. I wonder what it was...

      I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal

      Mistakes were made, my R34 Story

      HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.

      I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
