Whats ur ext gate doing? Is it just refusing to open?
From looking at some charts the 5E marks give u considerable more torque but the 4E give u alot more hp. Would definatly be nice to see some proper tests done.

is there some rr result sheets here on the sites we can compare some of them with different set ups
Only Aze_bs I'm afraid. Hang on I'll put em up here.

ive posted a graph before, if you givve me a few mins ill post it up again...
my wasegate isnt opening, i took it off and used air comrressor to open it and it work ok after i took it apart, but there is a TINY hole in the metal inside and i tink it must be causing it to stay shut. buy cheap buy twice

ok here we go about teh best comparison i can get. exactly the same setup but with 200cc increase...
4efte td04l @ 0.90bar 203bhp and 186 torque
and my forged 5efte td04l @ 1bar
so thats:
4efte td04l @ 0.90bar 203bhp and 186 torque
and my forged 5efte td04l @ 1bar 231bhp and 240 torque
from jsut a 5e conversion on 5e timing mark

do you think if the car was run on the 5e cam mark the torque figs.might of been bigger?

just one other thing is it worth putting spuddys engine at the 5e cam marks tomorrow?just to see if there is a differeance?

Had to nip out there for some smokes
I can hook up the laptop to the EMU, I'm not overly offay with the operation of the thing but I'm sure I can datalog.
I need to take it for a run tomorrow before I change anything cause of something Chris said I should check on the log. Then we'll (me and billy) strip it down and firstly check for abnormalities in the 4E timing and if we spot its wrong we can fix it and take it for another run and log it.
Lastly we'll stick it on the 5E marks and go logging.
What ever gives me the earliest/longest boost curve is the winner!
Unless of course I'm told in the mean time this sounds risky for the engine even with the ignition timeing set to stock levels.
