Well guys what can I say? I am simply dumbfounded by the results of yesterdays runs at PBIR. When I set out to be the fastest stock bottom Dsm I never guessed we would have been able to get this far. The 4g63 has proven to be one of the best OEM short blocks ever made and can still be faster but only time will tell just where the breaking point is on them. Here is a compilation of yesterdays runs:
OstarMotorsports Stock Block 4G63 Record 9.28 @ 154mph - YouTube
Some may be guessing what changes did we make from last year but all we did was change out cams , swap out the stock intake manifold for a JMF Drag and try a new Ostar Motorsports exhaust manifold . Boost remains the same at 39psi with the 3794 from Forced Performance.
