I am running at 1.4bar with no LSD, but it is next on the cards.
It is probably safest max boost on the TD04L, it maybe can flow more but if you want much more, I'd say get a bigger turbo setup...but then you get more lag.
if u look at a compressor Map for the Td04l it will show u where the turbo looses its efficiancy!!! once a turbo reaches its choke point u will not be getting any more power from ur turbo!!! shes just a heat generator then!! hehe!!!! so u want 2 map ur car just below the turbo choke line so ur getting the most out of ur engine and turbo setup!!!!
so for the td04l it seems 1.4 - 1.5 bar will run nice power on a forged 4E!!
best of luck with the car!! mite see u in the summer at the Pod and us Irish will show u wat a real 4E is capable of
i offered to pay him a deposit until the bank transfer had gone through and he said not to worry it was fine, he would keep the engine for me. and guess what, he hasnt!
