SLP 1.85 Rocker Query
How much HP would SLP's 1.85 rockers add on a stock engine? Yea, yea, I know for the money I should just do a cam. But thinking about buying a used set, plus they are easier than a cam. How much extra lift would it add?
The stock cam is .500 lift, and the stock rocker ratio is 1.71. So 1.85 rockers would bumo the valve lift to .541". Good luck finding a used set, these have just been released and I have yet to read about anyone having them.
I just installed these rockers on a 2001 A4 Trans Am. I gained 11 rwhp. The horsepower also stayed leveled out longer throughout the rpm. Not enough horsepower gain for the money at all. I wouldn't recommend this mod.
