VY Fuel Consumption
Hey guys, im planning to put a 87mm pulley an add a yella terra pipe to the original airbox on my vy supercharge, will the extra power make the car chew more petrol or will it get a bit better?
Logic says more boost = more air = more fuel = yes it will
Good luck getting the original pulley off the Supercharger if you have the factory SC unit. These SCs have been designed deliberately to make pulley removal very difficult. Research it first.
you would have to hire out or buy a pulley remover tool fit or yella terra will have one
yella terra is going to do it all for me, so thats no problems, thanks for the info

My l67 on 10psi does a best of 13.2 combined driving
My S/C Calais VY has a 10psi pulley/extractors/kn air filter/XU6 chip. I get around 9.7lt per 100klm on the open road & around 12lt per 100klm around the town. I am very happy with performance gains , yes it was VERY hard to get old pulley off , you need to get the tool plus a LONG breaker bar (about 2 feet long!!!) & it wrecked the old pulley getting it off. The Supercharger bypasses under normal driving so fuel economy is as good as a N/A V6. Its only when you nail the throttle that the fuel guzzles....Originally Posted by [QLIMAX]
those figures r an improvement for my car so if i was getting around that id b very happy! so does your car have extractors contected to the standard exhaust? and how much and what does the xu6 chip do? and whats your power like?
Interesting numbers.
My stock VY II S Supercharged returns around 8.5 litres per 100 kms in Highway driving at 100 kms per hour. I have recently done a SYD - MEL - SYD trip and consumption was always around the mid eights. I got it down below 8 a few times in highway driving.
I would need to be driving mine at around 120 km p/hr or more to get the consumption up to the 9.7 litres per 100 km mark. Around town consumption varies considerably depending on what type of traffic and the types of roads you have to encounter as well as driving style.
These S/C engines are so good I would not really want a heavy V8 again.
I guess you don't want to know that an LS1 is actually 8kg lighter than an emotec!
If your cruising on the highway you might find it to be slightly better, reason being when crusing the engine is "off-boost" ie the air is routed thru the bypass valve but its still heated by the supercharger cause its still spinning and slightly faster than before so hotter air = less dense air = less fuel injected
BUT when you boot it, expect your fuel gauge to drop rather quickly....
My old vt super6 did a best of 9.5l/100 from melb to brissy before the pulley upgrade and 8.3 after it without a tune....
I run a stock R8 exhaust from the cats back (fits straight on to S/C extractors but is a dual system right thru to the dual tailpipes. ) XU-6 chip gives approx 10 kw gains, probably thru remapping improvements, power is excellent as I said before very happy , also running a 10degree cooler thermostat as blowers love lower temps in engine bay, lower temp=denser air = better, cooler compressed air.....
Banned
i am lucky to see 13 highway driving... but my car was tuned shit...
i finally got my car below 13 today its at 12.8 STARTED SHIFTING EARLIER helps alot!!!!
