"In an effort to put out the best possible PEMs we've researched and hit a wall. The problem lies in the front header piece. Opening the inlet as people are isn't doing anything because the inlets are already 1.53" (as big as the port in the head). The problem is the lower section of the manifold. It's 2" OD and 1.63" ID. At that section you're sharing with the other ports.Trying to exhaust all 3 front cylinders out of a single 1 5/8" pipe is crazy. It's no wonder so many people pop front pistons and have questionable gains from other PEMs on the market."
Taken from ZZP's Power Log page.
My question is... is it actually dangerous to run my engine hard on the stock front exhaust manifold? What do they mean by people popping front pistons?
Am I endangering my engine by running 4k or 5k rpms on the stock front exhaust manifold? Do I increase the danger by putting an intake in, increasing incoming air flow?
One of the benefits listed is "Keep the front bank of pistons safer"
Is this only an issue for more modded setups? Im stock atm, intake would be my only mod.
Just trying to decide if I should do my intake now, or wait until I have the power log to install to keep it safe, cause needless to say Im probably gunna run it hard for the first few days after I put my intake on, lol.
