Thread: Turbo technics s208 grub screw adjustment

Have you got the tune from Ben for that turbo? He told me I had to adjust mine to bring it on boost quicker but I haven't touched it yet. Its a bit laggy at the start. I also have a tune from Shack on here and his tune comes on boost pretty much straight away. Although it's not as strong through the mid range as Ben's. Give Shack a message about it. He is really helpful and does great tunes for the td5.
Cheers

Got the tune from Ben,td5inside and Alive to try haha

I just got the turbo to play with untill td5zilla releases his turbo package and I’ll see what power that makes

Thanks for the response

By grub screw Iguess you're talking about the adjustment screw for the wastegate? (as pictured), mine was set when fitted and certainly don't have much lag if any.....

Yeah that’s itIMG_5265.jpg

found out today what the little vnt can do

Ouch, surprising. Auto or manual?

Auto, do you wind the screw down or up to close the vanes?

There are 2 adjustments.

Small screw “up” sets the vane baseline.

Adjusting the length of the rod from the diaphragm will then change how far/quickly they open under boost.

So make the grub screw longer or shorter for baseline boost?

Wastage is set as standard and runs 25psi
