My last one ran greens, 4x4 cooler, T34.55, BD10s, head work, @22psi peak, 20 psi held and made 294.6bhp & 350lb/ft on a set of DD rollers. (though it only hit 17psi while on them, it was ran in 3rd gear too).

Ha ha Dave!

I honestly have no idea of usual power outputs when it comes to levels of YB tuning... but i thought it sounded pretty good for such a reasonable boost pressure.

Boost pressure doesnt have that much to do with it, On a high flowing engine with a T34 you wont get big boost at max power, My old T34 engine made 402hp on 24psi on the engine dyno.

Seems a little high to me for that pressure:
0.48 a/r (old 98 RON with lots of benzine )



0.63 a/r (old 97 RON Shell, before it went to Optimax, but turbos didn't last more than 3 months at a time ).

4 x 803, but as I said, it was in the days of the proper fuel, before they took all the benzine out. Was sufficient to do a 12.614 standing quarter at 115mph (2wd) and 172mph, so defo had the power .
