Keep us posted, I have a very similar spec to you, once its stuck back together!! Will be interesting to see what to expect. I would be hoping for 350-360.

Anything around 340/340 will be a result. Although if you're on the std 440 injectors, that might be a limitation.
Don't chase headline figures, that set up will be a cracking drive on the road (been there done that).
Shouldn't be necessary to run much more than 1.4/5bar peak boost

Running 1.8 bar on a VF35 may be counter productive.
Contrary to popular opinion, more boost is not always the way to go. It is a trade off between boost and ignition advance and the VF35s I have been associated with have given their best a long way short of 1.8 bar. Once you exceed the efficiency threshold you are making a lot of hot air for very little power gain if any.

well its done and what a top job simon did , 1.45 bar and we got 345 bhp and 350lb torque
the only snag was on the run home it dropped a big end :-(
so looks like a rebuild in in the pipe line
im proper pissed off , big time

Gutted,good power figures but the end result is why id rather guesstimate my bhp etc, on the rollers on unworked engines (original internals) just seems to pop the shells,so it seems
......foook me mine was 3 yr old with 27k and said goodnight

I think it is more likely 101,000miles of oil changes with unlikely to have primed filter and engine before restarting etc and just 101,000miles on the bearings.. I don't think it is necessarily the power.. just obviously it need to be exercised to map it.. so any underlying issue is just going to rear its head then.

****e!! Sorry to hear that mate, although a 100,000 mile P! on a std engine is an achievement in itself. Give David at APi a ring. He'll talk you through the options. A rebuild that'll let you run 350 reliably shouldn't cost the earth!

Been keeping an eye on his, sorry to hear this , I had my 135,000 uk turbo mapped for the fourth or fifth time last week, only approx 300bhp, heart in my mouth, then find out a few days later both my rocker covers are leaking and possibly the centre diff!!
