Just wondered really,ive heard about a few people doing motorway miles but keeping the car off boost.What sort of speeds consitutes being 'off boost' cant be anymore than 60mph surely

any ideas

bits'n'pieces

listen to the turbo... if it's not spinning ur not boosting about 3k ish

Tandy

I get pretty good economy if I keep it under 3K about 80Mph in 5th gear, might be better at a constant 56Mph but can't be arsed.

You can keep it off boost at 100+ as long as the road is flat

greg.g

As brun said, you can sit all day at 80mph off boost as long as your gentle with your right foot

Heheh

Managed 300 miles on a tank (last tankful) but would hae to own up to a bit more hard pressing sometimes BUT when cruising, its around 0 bar of boost which keeps the fuel con down.

I kept it to 80mph whilst going to Scotland, was quite hard at times, just that little touch put you in launch mode, must be on edge of boost.

131mph for me Daz

Thats ok then i had visions of me driving around at 50 mph till the car is remapped.Didnt fancy a 5 hour drive to the pod on friday cheers guys

Look at your boost gauge

I would if i had one,they havent arrived yet

Sorry, couldn't resist that one.

Basically you should be able to drive at any speed off boost, just holding the accelerator at that exact rev can be tricky, and always tempting to squeeze it a little...

Have you had some new mods fitted and are awaiting a remap ?

0 psi boost in 5th is approx 90 for me on a fairly level road.

PHILYB

what revs is zero boost on a P1??

scooby L

I't not really revs though is it?

It's load on the engine, so you could be at 6,500rpm with no load=0 boost?

Throttle % would be a more precise measurement

marklemac

scooby L, yes, throttle position.

Tchort

I think about 3K but I just cant keep ti there, my right foot is to heavy

AvalancheS8

Any Turbo car can run at zero boost at pretty much any revs, it's just a case of using light throttle. You could quite easily hit the redline in 1st or 2nd without any boost at all. In the higher gears the power required to push the car along fast enough will exceed what is produced at zero boost though. It's not as simple as revs or speed being directly related to boost - e.g at 90 in 5th with zero boost my car sits at a constant speed, lift off a little and the boost drops straight away but the speed and revs don't change very fast, although they will slowly start to drop as the car slows. If, on the other hand I open the throttle a little I get more boost straight away, and the car starts to accelerate.

How did you quess FMIC is now on along with induction kit etc and im waiting on a new Andy F mapped ECU so i have to drive very conservativly to prevent running lean.I do have a Lambda link in place so although not 100% accurate should give me some sort of indication
