bombastic, is that city driving? or highway? or both?

how are you finding that solenoid boost mod? big difference in performance?

IIRC it was all in the suburbs/city.

When I first did the mod I thought it was a fairly noticeable difference, now I'm just used to it, so I'm waiting on a turbotech boost controller to bump it up a little :D

I don't see why performance should chew up heaps more fuel, unless you get on the boost every time you take off. Even then, you're still only accelerating to the speed limit and then cruising - what difference does it make if you burn fuel at a high rate for a small period of time (neglecting running rich on boost etc.), or at a low rate for a large period of time (like a grandma)? Either way, you should have a similar amount of energy being converted into motion and heat to get to cruising speed. Of course if the next set of lights go red then I can see how it'll be a big waste.

Excuse my skewed and probably-wrong theoretical world view :dry:

Mate i got a stock 33 s2 only mods are exhaust and pod, i constantly get 450 to 500km per tank, but thats before the light comes on, i did get 520km once just as the light came on, then filled up, still had around 5-8 litres left in tank. I don't boost it much manly drive just to work and back and occasionally weekend fang.

does it involve alot of highway k's?

coz i get like twice as much if it's highway.

Yeah, sometimes. Although its only for 15-20mins as work is close to home. Don't see much of a change when just driving around town, maybe closer to 450km a tank. I find if i don't boost it much then the fuel lasts alot longer, and besides around town or anywhere for that matter on the street you really don't need to boost it anyway, but then there's the track, where at wakie a few weks ago i went through 3/4 of a tank for the day!!! only did like 250kms!!! Can't wait to see what it uses at Eastern Creek ;)

      You're making my point for me. 95 is not "premium". It is a "slightly higher octane" version of the basic 91 product. The premium product that they want people to buy (for all the venal corporate reasons of making more profit, and all the possibly specious reasons of it being a "better" fuel with nicer additive packages) is the 98 octane stuff. 95 is the classic middle child. No-one wants it. No-one cares about it. It is just there, occupying a space in the product hierarchy.

      98 and 95 have to meet the same national fuel standards beside the actual RON.  91 has lower standards (which are quite poor really), so 95 is certainly not 91 with some octane booster. It would be an easier argument to claim 98 is just 95 with some octane boosters. Also RON doesn't specify 'quality' in any sense, only the octane number.  Anything different retailers decide or not decide to add to their 95 or 98 is arbitrary and not defined by the RON figure.

      95 is just a scam outright. 98 is the real "premium" with all the best detergents and other additive packages, and at least historically, used to be more dense also. 95 is just 91 bargain basement shit with a little extra octane rating. Of course, there's 91 and there's 91 also. I always (back in the 90s early 2000s) refused to put fuel in from supermarket related fuel chains on the basis that it was nasty half arsed shit imported from Indonesia. Nowadays, I suspect that there is little difference between the nasty half-arsed shit brought in by the "bargain" chains and the nasty half-arsed shit brought in by the big brands, given that most of it is coming from the same SEAsian refineries. Anyway - if there's still anything to that logic, then it would apply to 95 also. 98 is only made in decent refineries and, as I said, is usually the "premium" fuel, both in terms of octane rating and "use this because it's good for your engine because it's got the unicorn jizz in it!".
