JPM Raptor Power Jet

Raptor Powerjet! A third fuel system for IDA carb. Makes the power band wider with a big increase in low and midrange performance, also some improvements in highrpm. Reduces the richness when throttle is opened suddenly at low rpm. Reduction of main jet, approx. 20-25numbers(165-140). The Powerjet has it's own jet which can be changed, delivers with three different jet sizes.

  • Makes the power band wider and smoother
  • More power through the rpm band
  • Go wilder on street performance
  • More cam etc, still very driveable
  • Very easy and quick to install, all parts included in the kit
  • Old main fuel system now works as a mid fuel system and the powerjet as a high speed fuel system.

JPM Billet Cylinder

Ring för pris

JPM billet cylinder is made from cast iron with a very solide structure.  The material is commonly used for hydraulic cylinders with pressures that never is experienced in a combustion engine. The choise of material prevents the cylinder to expand too much and therefor the valve lash is still controlable when engine is hot.  A common problem when stepping up to 94mm bore is big crank case  breathing. The crank case breathing is because of a not circular  cylinder, too deep releases i for the head studs makes the cylinder like a square when torqued. Too big difference in material thickness causes the cylinder to deform when torqued.  


PM billet cylinder has a very even thickness and therefor it is perfectly round when torqued to  specification. The OD of cylinder at top is made bigger(102mm 4.015")  than std(101.1mm 3.98").
