Hi all,

Would it be OK to fill up the R34 GTT with 91 RON petrol and then treat it with Nylon Pro octane booster?

From the reviews Ive read, Nylon Pro is the bets one out there and raises the octane rating past 98 PULP.

Its just I can get access to 91 petrol but not 98... atm.

If that's all you can get where you are atm, then it'd be best to do just that.

Whatever your mean average RON is, sitting in your tank atm, the octane booster is only going to shift it up marginally.

You'll get a better result with toluene (ie methylbenzene), depending on what amount you put in; but through regular skin contact and inhalation, it's carcinogenic.

if you got 98pulp in your tank and you drop in octane boost

how much more would it raise the pulp?

105pulp?

Doesn't quite work like that mate. As in theory adding more octane booster again would give you 111RON, then 118RON. Until you ended up with 300RON super fuel to run an engine with 37:1 compression...... laugh.gif

Running Octane booster in general is a bad idea.

A once off is ok for emergencies... But then you can just stay off boost/light throttle and you'd be fine.

If you keep using it you'll run the chance of fouling plugs after a few tanks, and that'll make it just 10x worse over time than using proper fuel :)

a mate of mine was a mechanic for repco a few years ago (the local repco store had a workshop on the side of it) and one day the nulon rep came through and had an octane test kit with him. my mate grabbed some BP ultimate out of his car and they ran a few tests. first they tested the fuel by itself. it was 98 octane (as you wuold expect). next they put in the standard measure of the pro strength octane booster (i think. this was about 5 years ago now so the memory is a bit dodgy). pretty sure this put it up to about 103 octane. then they put in double the normal dosage. the octane rating actually dropped back down to around 99 octane.

just run it on 91, unless you have an aftermarket ecu tuned for 98 it wont be a problem. with a stock ecu your better off with 91 than 98 anyway.

if you use octane boost make sure you have plenty of cash for spark plugs, you'll be changing them every 2nd tank. not to mention o2 sensors and other shit like that

are you missing that he said it was for a GTT, or are you taking the piss? the stock turbo ecu is tuned for minimum 95 octane fuel. running it on 91 octane will result in a loss of power, or if the knock sensors aren't working correctly a damaged motor. 95 or 98 octane will result it more power and safer knock levels.

Most people know that Australian 91RON unleaded is basically served as shots in Japanese bars... Our fuel sucks. Thus, imports not originally made for the Australian market should be run on 95 or better...

    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
