GT2052S project thread number three

[306Puggy]

Thanks for the quick replies chaps.

I really don't think it could be a boost leak because as I go further up the rev range I would expect some increase in boost but it just seems to be flat as it is in the low revs so it is really only in the mid range where the Bosch delivers peak fuel that it seems to make any boost.

None the less I shall try removing the boost controller and try the WD40 method as well as I don't have any brake cleaner. Piggy the shaft does have some side to side play (perhaps 2-3mm) but I have read that they all have play without the oil bearing.

Thanks and I think I will be scouring the for sale section for a TD04 very soon as GT20 series units are hard to get hold of.

Edit:

Just seen the above conversation.

I cant believe its too big to spool either. Hot side isnt all that big

This is flynn though.. the pump is most prob slightly tuned and thats it.. no gov mod etc.. im not sure if the fuel is still starting to cut off at a standard amount if ya know what I mean..

Yes the governor is modded and the LDA pin has been grinded down. And it is running enough fuel for 30 psi on the K14 unit.

Likely he is probably matting it...

But it should still spool and clear

Yes from what I have read a GT20 should respond well to foot matting as it spools very quickly so I have just been giving it everything.
