hello peeps.

i have just seen some uprated wastegate springs available, meant to stop boost creep. good or bad thing ??

it can only be good yea/no ?

only a tenner and easily fitted ?

I think it helps out when your car is remapped. Most of the creep control is thru the electronic boost control tho

You will need your mapping altered as it will produce slightly more boost.
But should cut down on lag..i presume you mean the ones on ebay?

martin

Yes those ones, i ordered one anyway.

The boost pressure is controlled by a dedicated calculator in ECU, then changing the spring is not clever and maybe dangerous (for reliability). The spring force have to be fitted in accordance to pressure mapping of calculator and help in transition periods only!

so fit it when the car is about to get mapped ?

Not sure about this at all. Did similar on old SAAB 900 T16s but that had little ECU input c/w RS2 and still Abbott racing had to spend time to set things up.
David I found Scott at AMD very helpful over the phone and his only advice for my car @77k to ensure consistent boost was to replace the diverter valve Bosch p/n I will check if interested but same as porsche 944 turbo

I wouldn't play with the spring - Tuners will put in a stiffer spring and adjust the pre-tension on the spring but that should only be done along with a remap to account for it.

i also need one; but do not have any idea about the tension should be.....is there any www for these stuff?
thnx,
