rob wild Posted September 25, 2004 Share Posted September 25, 2004 Hi, I have j-spec Twin Turbo and i have used Optimax for about 6 months, after i tried it for the first time in my soop. I does make a difference as the my car feels much more responsive, as far as measurable performance difference i did try a 0-60 time (using a race logic data logger) and to be honest i tried it with and without Optimax and actual difference was not much i.e. just point of a second, but that could have been down to a number of factors i.e. road conditions and driver skill!. My mate who got me into supra has a N/A j-spec, blitz exhaust, induction and few other bits and pieces as well as a 100 shot of NOS, and when he's using the NOS it is V.fast and according to his estimation it should be kicking out just over the 300BHP mark. As far a wasting a Scooby i had a WRX turbo that was around 280BHP and it fast and I would say if both car were in standard form the scooby handled better than my soop when i first got it. As the Soop back end is very twitchy! As I’m sure you are aware! Good news though I did waste a mate 97 wrx turbo scooby at oulton park recently, and i would say mainly since i have had strut braces front and back, lowered and some uprated disc and pads!

Dave Posted September 25, 2004 Author Share Posted September 25, 2004 thanks for the info rob has your mate with the 100 shot of nos got any internal engine mods or is it std has he got a progressive controller and yes i found out the back is twichy had her sideways round a bend racing a bike needed a change of pants after that good job the road was wide lol Link to comment Share on other sites More sharing options...

dangerous brain Posted September 25, 2004 Share Posted September 25, 2004 I have an N/A running a 65 shot of n2o (untuned at the mo). As far as running the car on optimax I really can't say that I notice any sort of performance difference with the optimax over standard unleaded. Also if anything it runs out faster than standard unleaded does. I have no issues with the fact that it does improve performance its just not enough to be noticeable. You whack in some of the more reputable octane boosters and yes that does seem to give you a bit more go. But heres the bind it seems to lose power from the lower end of the scale when it does it. So you seem to get more power (noticeable) in the high rev range ie the cars natural power band, but you lose power lower down the rev range. I have found this so far for every MOD I have done on my car. The big assed exhaust I was expecting to release up a bit of power did so at the top end at the expense of lower end power. The octane booster I put in did exactly the same thing. Now heres summat interesting untuned and without progressive controller the nitrous also does exactly the same thing. Now I am thinking that perhaps in the lower rev range all these MODs are effectively overfuelling which is why you seem to be losing power down there. When the revs get to the point they can burn all this fuel/nitrous/octane/easier flowing air they do so giving you the extra power feel. A remapped ECU would seem the logical step to sort this out but they really aren't cheap. You want to beat a Scooby get a TT or learn to drive round corners with more balls than sense.

rob wild Posted September 26, 2004 Share Posted September 26, 2004 Ye totally agree with that my mates N/A has a progressive controller, and a piggy back ecu and it’s been map on a rolling road, but he has spent a lot of money doing that! That’s why he can give my TT a good run for its money. And that’s why I’m now buying a boost controller and e-manage to pump my BHP up! Nothing wrong with a bit of healthy competition! It a shame that it cost so much! Link to comment Share on other sites More sharing options...
richy2jz-gte Posted September 27, 2004 Share Posted September 27, 2004 esso super unleaded is a lot better in my supe than optimax i can tell the diffrence from running optimax then puttin esso s.u in, if uve got the same optimax in the tank for a couple of days it tends to go off, feels like ur pulling a trailer full of bricks.

Funny old thing you say that because esso super is actually only about 2p a litre dearer than standard unleaded up the road from me at the mo.

trooper Posted September 28, 2004 Share Posted September 28, 2004 I get better MPG with Optimax over regular 95 octane fuel which is measurable. As for performance, it FEELS better with Optimax but I haven't measured the difference. Probably very small but it all helps. The biggest problem I have is deadness from idle which isn't affected by fuel type. Bloody turbos. Link to comment Share on other sites More sharing options...
dangerous brain Posted September 28, 2004 Share Posted September 28, 2004 Top of thread we are talking About N/A's here. Its an accepted fact that optimax is better in turbo's (in fact some wont run without it). But N/A's actually generally use more of it than 95 RON for little gaugeable gains.

trooper Posted September 28, 2004 Share Posted September 28, 2004 Soz, must read the thread better next time. Optimax is advertised to be better in non-turbos too but if there's no performance increase and no better economy, why bother? Link to comment Share on other sites More sharing options...

Have to disagree with you Brain and trooper!! But there is a markable difference between standard unleaded and optimax/ultimate. You can really feel it in my car and pick up is much improved. However, using octane booster on top of Optimax, does not give a noticeable difference.

Shell standard 95 ron or murco has RON honest Maybe I just can't feel the extra half a horsepower it delivers or maybe my spark plugs need changing or something but I genuinely can't feel any difference with optimax. I use it mainly because it has more additives in than 95 RON does in the hope that it treats my poor ickle engine and fuel system better. Link to comment Share on other sites More sharing options...

Shell standard 95 ron or murco has RON honest I have tried bog standard Supermarket (tesco and sainsburys), texaco and shell, which claim to have detergents in to protect your beast on the inside. I personally do 1 fill cheapo and then 1 gud stuff, except when I go to shows or meets. Then I put gud only in so the TT boys don't rip me apart too much!!

It causes detonation which I beleive can eventually lead to buggered engine and hence then won't start lol. AFAIK there are quite a few members of the board who's cars wont run properly without decent fuel in them. Link to comment Share on other sites More sharing options...
carl0s Posted October 1, 2004 Share Posted October 1, 2004 My UK TT auto feels very noticably quicker on Optimax than on regular 95RON Shell or BP. On 95RON it feels pretty quick, on Optimax it feels like a very fast car. I use regular 95RON mostly 'cause all fuel is too expensive now. Link to comment Share on other sites More sharing options...

Its a well known fact that TT's produce more oomph on optimax. The N/A's however which is what we are discussing here generally speaking don't seem to.
