motor. It is in the very early breaking in stage so I can't personally tell you what the boost *feels* like. Jason with the silver Z that did the SCC street challenge last year has the other set in the states and he says they get full boost around 5K ands aren't bad at all on the street. He will be dynoing soon. Yacoub in Qatar has the other set and he loves them :-). No dyno's in Qatar so unless he ships it back over we will have to just say it will be more then the 630 rwhp he already put down on the TD05-18G's :-). All three sets are on Greddy manifolds for now. I have two more cars lined up to do TD06 turbos with the Pentroof manifolds and of course Bryan's and William's cars on the 2835's and pentroofs. I think out of all the cars though...Bryan's will be the highest Rwhp because he has spared no expense.
