MRP Custom Long Rod 7age Setup

This kit is designed by MRP and caters for the ultimate 7age enthusiast.
Featuring a much longer rod coupled with a short piston design giving a rod/stroke ratio of 1.63:1.
The standard 7a rod/stroke ratio is 1.55:1, a stock 4age rod/stroke ratio is 1.58:1.

How this helps performance?
A longer rod makes more torque with the same piston force, and since it’s less  angular than a shorter rod, reduces sidewall loading and decreases friction. All  of this adds up to more power.
Longer rods also give the pistons more “dwell,” the  brief periods of time the piston is at top dead center and bottom dead center. A  longer dwell allows for better flow of intake and exhaust gases since the piston  moves slower between up- and down strokes.
Longer dwell also offers more time to fill the cylinders  during the intake stroke and more time to scavenge during overlap. And since the  piston hangs out at or near TDC longer, the combustion stroke has more time to  deliver a thorough release of energy on to the piston.


The kit features:
Billet 4340 MRP Spec H-Beam Conrods at 5% longer  – With ARP2000 bolts standard (Upgrade to ARP 625+ is available +$300)
Custom Forged Traum Pistons made to order in any compression ratio and to suit both 16v or 20v heads (With Total seal rings & Gudgen pins)

Note: Normal 4age pistons will not work with this setup, for this setup to work the kit must contain both our items matched together
