The facts.... (compressor side) compressor Wheel = 71mm exducer and 53mm inducer compressor wheel has 7 blades exhaust wheel has 11 blades compressor housing still has 2.5" inlet compressor housing has M11 stamped on it whereas old super 60 had M27 on it... any ideas?

Saints turbo is rated to around 450 but its bigger than mine as he has 76mm exducer and 57mm inducer... I'd have thought mine would probably max out around 420ish... But with a 63ar housing?? Can't wait to get it back together now..... Mechanic is dragging his feet, he really doesn't like working on my car! Might find someone else near by to do it as i'm gettin ithcy feet now!

So do you think i'm being unrealistic for thinking sround 370 peak..... There are loads of cossies making this on the 48 housing!? Glad i've gone this route tho and stuck with the 48 as main priority is minimal lag! Nick 368bhp @ 1.5 bar

suba Unregistered S	You'll probably find that most cossies will be running 2 bar of boost to get that figure though. The 48 housing sounds small compared to the compressor wheel, but I am not that familiar with the T3 / T4's....

Anyways had some good news on the rebuild front.... Just gotta source some piston rings now and I have all the parts the garage will need and they reckon they could have it done in around 8 hours...... Seems optimstic to me but what do I know hey! So may have car and start running in within 10 days.... WAHOO! Nick 368bhp @ 1.5 bar
