wiresquire Member 266 Member For: 19y 5m 3d Posted 14/05/10 01:40 AM Share Posted 14/05/10 01:40 AM hey, yeh mate iv reset it all.Im averaging around 17ish now. My average Km/h is only 29-30km/h though so that's my problem I think lol mainly just suburban driving and that. Im guna clean out the carby this week as well as the Actuator solenoid to see f that makes a difference (plus make it run even nicer)cheersFor that avge speed, your fuel figures are normal. Stop/start, car parks what can a bloke do?The only other thing that might play into it is fuel. You are using 98, right? Anything less will normally give you less kms.ws Link to comment Share on other sites More sharing options...

Im trying a few different servo's and taking note of the figures to see if theres any difference.cheers Link to comment Share on other sites More sharing options...

f-wolf Member 897 Member For: 17y 4d Gender: Male Location: ACT Posted 25/05/10 05:07 AM Share Posted 25/05/10 05:07 AM (edited) 91 - big no no for turbosBA XR6 NA . One good thing is - using a 9.7:1 compression ratio - the engine can survive on cheap-o 91RON ULP rather than the higher-octane stuff.BA XR6 Turbo8.7:1 static compression ratio combined with very mild boost pressure. With the turbo set to deliver just 6 psi…Compression ratio 8.7:1 Fuel type 91/95 RON ULP The XR6 Turbo engine varies from its atmo cousin by employing revised pistons (dropping the static compression ratio from 9.7 to 8.7:1), slightly modified conrods and Inconel exhaust valves. The turbo system comprises a stainless steel exhaust manifold with a Garrett GT40 ball-bearing turbocharger, a high-flow cat converter and exhaust, front-mount air-to-air intercooler, Bosch blow-off valve and electronic wastegate control allowing up to 6 psi boost. Fuel pressure is also raised to 4 Bar and 95 RON premium unleaded fuel is necessary to achieve the quoted 240kW output. **********************************The XR6 Turbo According to Ford - Part OneFrom : AutoSpeed - The XR6 Turbo According to Ford - Part OneHow did you arrive at the chosen compression ratio and turbocharging"The compression ratio was assessed in a number of tests. You make an assumption to start with that we'll lower the compression ratio by X amount and see what the spark characteristics were like. We knew we were going to be spark inhibited with the standard compression ratio - it needs a lower compression ratio, otherwise you give yourself a too-hard time. You need to get into very high quality fuels and we wanted to make sure - using a knock sensor - we'd have the ability run on standard unleaded. That was a prerequisite. There is a performance benefit on premium unleaded, however."We were pretty fortunate in that we nominated a compression ratio and it turned out pretty close to what we wanted - we didn't have to go through a whole gambit of ratios. Don't forget we've got a lot of basic 6-cylinder technology already intrinsic within the company - like where you need to go for detonation borderline characteristics and MBT (mean best timing relating to torque) so the characteristic of the engine was pretty well known before we got into it. It wasn't really a guess; we ran with 8.7:1.Part Two at: http://autospeed.com/cms/A_1904/article.html Edited 25/05/10 05:13 AM by f-wolf Link to comment Share on other sites More sharing options...
Paulie2256 Donating Members 7,441 Member For: 15y 5m 7d Gender: Male Location: SE Melbourne Posted 25/05/10 06:08 AM Share Posted 25/05/10 06:08 AM I am going to assume 2 things from the above post. 1, your car is stock and 2, you never drive it hard. Ford have said and done a lot of stupid things over the years. One of the things that come to mind is putting conrods from the 60’s into a boosted car. Your car will run on 91. I never said it won’t, but don’t be naive in thinking because the engine has knock sensors that it’s safe. I believe the reason Ford say its ok to use 91 is so they can sell more cars. The average Joe family man wouldn’t buy it if Ford said to use 95 or above. There are many other turbo examples in the market from Japan and Europe none of which mention the use of 91.What if your towing something or accelerating up a big hill in 35+ deg day. Do you think the engine wont ping? I can almost guarantee it will. Why risk it just to save a few bucks. The higher octane rating is not the only advantage. 98ron fuels have additives which clean and de-carbonise the engine. You obviously love your car otherwise you wouldn’t be on this forum. So why feed it sh*t food? Link to comment Share on other sites More sharing options...

I have done 8000 km at the moment and I get 8.4 lt on the highway and get 14 lt around town. Hope it drops a little more in the future. Link to comment Share on other sites More sharing options...
