As cylinder pressures, springs pressure and rpm increase, the stress on your factory pushrods increases far beyond the level of stress your factory pushrods were designed for. If you are above 750 HP with your ISB you need to upgrade to the extreme duty pushrods. If you are over 750hp, the cylinder pressures acting on the valve can bend your OEM pushrods before the valve opens. This can retard cam timing and reduce valve lift.These pushrods are a 3 piece design that features 12mm diameter. 120 wall, which is much thicker than the OEM 3/8 or other performance shops 7/16 Diameter. Stock springs have 78-82lbs of pressure seat pressure on average at 1.380.
If you are over 35 PSI (boost or drive pressure) and 3,800 RPM, stock springs do not fully control the valve train. This allows a few negative things to happen. First, valve float, which can cause serious damage to the valve train.
Second, intake and exhaust valves can be blown open by boost and exhaust drive pressure which allows reversion. Reversion can hurt your power potential by allowing exhaust gasses to enter the cylinder on the intake stroke. Inert gasses in the exhaust, when re-introduced into the cylinder shield the fuel particles from oxygen in the cylinder. This does a few things that negatively affect power. It increases the time delay from start of injection to start of combustion, it decreases the maximum pressure and maximum temperature reached in the cylinder and it increases the total time needed to completely burn the available fuel.
Correct valve spring pressure is a very important piece of power production. Triple Shot peened and stress relieved. We recently slightly lowered the pressure on our springs from 110lb to 103lb. Nose pressure has been lowered from 220lb to 180lb. Watch out for other companies that have nose pressures over 250lb.
Your cam will have a shorter life with 250lbx2 (500lb) versus 180lbx2 (360lb) over the nose of the cam. Dont just ask what seat pressure is when you are shopping for springs, ask what the pressure is on the nose 1.031 with OEM cams or. If you are running over 4,500 rpm with a large cam, we suggest going with our 103lb springs with different heat treat and shot peen, for better longevity in extreme applications, as well as our light-weight 4130 or titanium retainers.Warning: Warning: not all 24valve springs are created equal. Recently we have started seeing other companies market products that are called 110lb 24 valve springs, when in reality they have 117-119lb of seat pressure and almost 250lb nose pressure at. This spring can cause major lobe wear to anything over a stock lift cam.
ALL of our cams have more than stock lift. For comparison, our 103lb springs have 102-104lb seat pressure and 180lb nose pressure with the 188-220. If you run a cam with more than. 320 lobe lift and anything other than the 103lb spring you run the chance of experiencing coil bind before maximum valve lift is achieved.
