Do they or dont they effect it, had this conversation with a friend of mine and they only way we think that it would effect it would be because your changing gear that often to hear the whoosh, hence the fuel consuption.....

Any other opinions?

 

You and your friend are absolutely correct!
Speaking for myself, I tend to take the revs up that little bit further for a louder dump, especially if there are frail old ladies at the bus stop

vta will increase fuel consumption due to ecu adding fuel avery time u loose the allready metered air

 

Ha! About 0.000000001%! And that's not being childish...
You could equally claim that the VTA raises engine efficiency through not re-routing oil (as the recirc ones do) as oil reduces the effective RON rating of the fuel, therefore retarding ignition,reducing efficiency therefore wasting fuel.

 

I has opened a can of whoop ***

Last couple of weeks i have being averaging around 19.8mpg before this i was getting around 21-22mpg.I have taken off v.t.a bov and re-fitted my standard one to see what happens over the next few weeks.

 

What'll happen will be you'll drive differently. Whether you mean to or not

How much time do you spend changing gear? 5% of the time (what your figure above would suggest)?
Um, no.
The car sounds better when driven hard with a VTA, so we all drive harder

So, I suppose yes, VTA does increase fuel consumption, but not itself - just because you are more likely to drive aggressively.

Does that help?

 

try the hks it will swallow fuel and not because of different driving every time u change gear at anything above atmo on ur boost gge ecu will add fuel

 

 

good,more fuel down the exhaust will give me bigger flames!!!

(flamer kit on order through scoobynet group buy )

 

so do they or dont they make a significant difference or is it so small it aint worth bothering about

"They" don't make any difference - whether the car becomes less economical or not is up to you. Wear earplugs & you'll get the same 'economy' () as before, listen & play with the new noise & you'll use more fuel

 

Actually i found my self driving the car less 'AGGRESSIVELY'due to feeling a little self-conscious(some times to loud).
