Any time you wanna try and lay some smak on me (will make a change from you smoking it) I know chris is in cyprus, I know the temps out there, increased nitro adds air which compensates for the thin atmosphere...

Low barometric pressure also lowers the engines efficiency already, the same as adding a shim... Higher humidity may well be an issue... extra water in the air increases the combustion chamber pressure and a shim can reduce this... reducing the BMEP...

Skyline, thanks for trying to patronise me, I do understand how these engines work, I also understand the variances about fuel etc, but if you actually read what I put, I merely quoted the manual about the shim, where Alex said it said something else... Thats with his 20 and 25 gallon engines he got those manuals i suppose...



Chris, I am coming to Paphos on the 20th August, if you want to meet me, I will sort it for you... Or at least try to... I can also bring another V-Spec you are welcome to try...

We can also check the piston and head for the tell tale sand pit marks that will show whether detonation or pre-ignition is a problem.

One of the things that either of the others fails to mention is a lot depends on how you drive...

If you blip the throttle a lot, you can find that the carb will spend a lot of time in the mid range and this can overheat an engine that seems perfect on top and idle...

Also, make sure you change the filter regularly, if you dont you will always be chasing the needles... especially with the dust out there...
