Piper 285 cams
Re linered block to 86mm
86mm omega pistons
TTV lightened and balanced flywheel
Alloy bottom pulley
Full bottom end balance
Jenvey 45's on adjustable trumpets
3.5 bar FPR
Re angled gti-6 manifold and magnex decat system
I was expecting around the 220bhp mark with strong power up to 7500/8000rpm.
Turns out it peaked power at 6500rpm at only 200bhp.
What do you think has limited this engine. It was a new build done by a proper engine builder but I have not contacted him yet to ask about cam timing.
Do you think the adjustable trumpets would restrict the engine to much as they have an internal bore on 42mm so even smaller than the 45mm jenvey.
Any thought would be great fully appreciated.
