boooooooooooost Strangeness
Turbo Mini Forums

My car displays some very odd strangeness
If you rememeber it has been on the RR and had a needle change etc so it should be running with good mixture through the rev range no probs .....

I have noticed that on boost levels of 0-5 not much happens AT ALL no real accelartion gain ... dont really feel anything ; its only when it goes from say 6-10 that it flies

What could cause this strange state of nothingness

As i am no turbo expert I feel a bit lost !!! is this turbo lag ?

If it was set up for 'max boost' of 5 psi, it'd go a lot better... As it is, running more boost means that fueling and ignition at lower boost levels are compromised...

I woudn't have thought it'd be that obvious though...

you using a MBC b12?

hey td & feeeeeeeeeeeeeeeeeeeeeeeebs

The car was dyno's for 9psi ! and a needle found to suit !

I did have a mbc but it was shite so it was removed during the session and I just connected back the bleed valve !

mebe I need to get it on the rollers again ; as i said I really dont know enough about turbos to work out what could cause this

I may up the Fuel pressure at idele up a bit

Or try again with the choke out ( to richen things up a bit )
