Boost Controllers

[Epyon]

Hi,

I have a automatic R32 and i few questions about boost controllers,

Would like to know if i increase the boost to say 12-15 psi will i notice my fuel usage increase at all?

And also

If i had a boost contoller with an in cabin controller would i be able to crank it up when i need the power.... then turn it down to say 5psi when i want to conserve fuel??

Anything would be appreciated.... i also found the thread about an awsome manual controller from ebay .... but it doesnt have a in cabin contoller...

Anyways thanks in advance for the tips

wanna save fuel? DON'T BOOT IT. its that simple. It doesn't matter what boost your running.

in answer to your question, if your fuel consumption will increase if u use the 12-15psi(full throttle) i dont see the need to lower your boost to 5-7psi, if your using full throttle to make 5-7psi then you obviously are meaning to do it and want more power so i'd leave it set on the higher 12-15psi so when u need the power you've got it and dont need to keep changing setting, obviously when your driving around town on light throttle u dont use boost hardly at all so fuel consumption is less, once u want the power and are using 12-15psi of boost then u get the kick in the pants feel and ur tank is drained accordingly, more power=more fuel... cheers

so if i had it running at 15psi and drove it like a grandma would i still get my 9-10 L/100km

pretty much, when u set a boost level, lets say 15psi for example. its suppose to be a max setting u want to run, now sometimes there spiking and sometimes there boost fade up in rev range but generally u can make the figure set unless theres other problems, but only time ur car will make the boost is under heavy load( full throttle) so aslong as u drive it with light to cruise throttle then your consumption of fuel shouldnt be affected too much, put your foot down and you'll know about it, stock boost is very dull after 1st gear, increasing boost is a good way to add mid-top end to it...but with this makes engine a little more thirsty... cheers

Yes.

My car stock is around 12psi. now i have bigger turbos, higher boost, power fc and a fully rebuilt motor with forged pistons and i have better fuel economy. when i get my boost controller and up the boost to 18-20psi, i will still have the same fuel economy on the road as i drive like a grandma. you control how much fuel you use with your right foot.

Agree with everything above.

Just add that turning the boost down (you mentioned 5psi) can only go as low as what your actuator is set at, no lower.

So if it's an R32, the actuator is a 10psi job, you can add a boost controller to go up to 50psi if you have all the supporting mods but you can't go lower than 10psi

....unless you change the actuator to an R33 job which is 5psi

Thats the joy of owning a turbo car.

Drive it off boost and it pretty much consumes as much fuel as any other 2.0/2.5L, but the power is there when you want it, just need to put your foot down and watch the fuel gauge droppppp!

Thanks,

if u boost ur car up to 12-15psi ull have to get it tuned for high boost...therfore ur petrol consumption will suffer.

It'll only suffer when on the gas but the extra power is worth it.

If your off throttle or on light throttle, it'll be in another part of the map and should be tuned for that accordingly.

So, yeah petrol consumption can still be kept to a minimum if you wanna use it as a commuter for example.

For fuel consumption, my 165rwkws tune = my 195rwkws tune = 240 rwkws tune...... when on light throttle

I could always get close to, or on 500kms per 55-60 litres when commuting on the freeway.

But the 240 used more than the 195, which used more than the 166 when on the gas
