torque plate exhaust spacer

[rtarford]

i did the search , but could not find any one that did this one mod to verify the 1-2 mph . i have 3 na skies & 2 sc skies and would like to buy 5 of them if they work . if not i'll get 2 and let every one know the results

40 to 60rpm is the norm.. So .5mph.. BUT, it helps keep the piston crowns a bit cooler..

so i would assume that is on a sc ski ? have you done that one mod yourself ? 80 - 150 rpm is bs ?

Yes on my own ski and a several others, stock and modified SC ski's.. I never saw more than a 60rpm gain but that's just in my region of Socal

i dont really know if it actually gains any rpms, but it does give the burnt exhaust a longer path of straight travel instead being burnt and making a instant turn into the manifold,

Great addition if one wants to log individual cylinder AFR and/or exhaust gas temps.
