Any built motors with S2 blowers out there?
I have the following modifications on my 01 S281SC:
Ported S2 blower
Ported intake manifold
2.6 pulley
S4 IC with air diversion kit to cover the gaps inbetween the ic and manifold
Ported S5 inlet kit
Densecharger fenderwell intake
90mm LMAF
42lbs injectors
75mm T/B
SCT tune
SVT Focus pump
Bassani O/R X pipe
FRPP Shorty headers
TR6 plugs gapped at .36
With just the ported blower and 2.6 pulley I was hitting 9.5 psi by 5.5K rpm's and made 345rwhp/381rwtq before pegging the maf at 5.5 rpm's. Today we just finished adding all the other upgrades and I hit 13.5 psi at 5.2rpm's. Call me crazy...I am not sure why I had so much boost? I expected to lose a couple pounds of boost while porting the manifold, matching the heads and adding the ported inlet kit. Regardless, my question is about building the motor. I have been told by several well recognized Ford tuners that a well tuned motor can handle 425rwhp without a problem. I have not tuned my car for the new additions but can only say it feels super strong. I would say I am under 410rwhp and under 435rwtq.
At *this* level what should I be most concerned about? I have never heard of any problems with the rods bending, streching or breaking. Should I be more worried about a burnt or cracked piston. What are your thoughts...
