Yesterday I finally got some dyno time in the turbo Capri.
The spec is basically;
205 block with standard crank
YB pistons, rods, oil pump with spray bar and YB winged sump
Moderatly ported head, standard valves, NH206 cam
YB intake with "Swedish" style plenum, 3" throttle body
4x4 Cosworth Sierra intercooler
Custom pulse split exhaust manifold, 60 mm wastegate
Holset HX32 turbo (8 cm2 single inlet exhaust housing)
MS3 management with MS3X, crank trigger and EDIS coil in wastespark mode
875 cc/min injectors (runs on pump fuel, 98 octane)
We had an issue with a trigger fault or something at 6300 rpm so all runs were ended at 6000 rpm. Base line boost is 1,1 bar (16 psi) and with minor adjustments we made 226 whp @ 5960 rpm and 325 Nm @ 4574 rpm.
The engine seemed to like boost (and igniton advance) so we turned the go-fast knob a bit and ended up at 1,8 bar (26,1 psi). 284 wph @ 5964 rpm and 398 Nm @ 4410 rpm.
At this power level the intercooler is a bit small, it gets saturated so it needs to cool down a bit to repeat the results.
The roads are now cold and damp, almost icy, so a test drive only gives wheel spin. And a grin! :-)
