JHH PERFORMANCE ENGINEERING MOTOR ENGINEERING FOR PERFORMANCE FOR 33 YEARS
Racers such as Col Dunne (Superformance), John Haines (Haines Hunter), Barry Taylor (Phase 4),Wally Puskie (V8 Drag Bike) Rod Otto (T Bucket) relied on our heads and engines to win. We
noticed in the late 1980"s that 4 Valve and EFI Technology was appearing
more in production engines, as we already had done design and modifying
on 4 Valve Racing engines we set out to develop porting design to
give maximum performance without going outside the
 tuning
perimeters of the production ECU, and consequently the STREET FORCE
cylinder head was developed .
We do all our Cylinder head work and most of our engine building inhouse to ensure a high quality final product. Our dynamic balancing in particular is a balance that is not only accurate but mechanically strong , with metal removal on rods and pistons not affecting the original design perimeters. Cars we have worked on click on the owners names.
