Turbo Lagg

[scalci]

What can I do about my LC 80's turbo lagg?

Try this for starters.

Works for 12 valve as well.

You can hear my turbo spooling up before it gets to 1000rpm.

Also cut out the main exhaust box replacing it with a straight through pipe - this drastically reduces the back pressure and then when you increase the fuelling via the boost compensator it picks up well from low down - with a bit of tweaking I have very little turbo lag

After I did some investigation, I saw my exhaust manifold is cracked. Will this cause turbo lagg?

I still have some oagg. Any ideas?

 

[adrianr]

Can u be more specific.

When are you hearing turbo spool up?

You will always have some lag.

Can't say as I notice any lag in mine, just starts pulling and builds. The A8, now that had lag, but it was worth the wait

Boost at lower rpm's is dictated by the amount of fuel put in initially, quite simply more smoke low down = lowering the boost threshold (or what is often wrongly referred to as lag) Adjusting the fuel pump will have the most effect, its that or resize the turbo.

it is from start to about 2000 rpm.
