I am looking to squeeze some hp out of this motor if anybody can help me out... Everything except buying a new Rotrex :P

My mods:

• Stock Block
• Supertech Retainers and springs
• Brian Crowder Stage 2 cams
• Stock header
• Test Pipe with a js 70rs
• KW Kit C30-94 @ 6 psi (already ordered a smaller pulley to reach 10 psi)
• 650RC Injectors

Mustang Dyno Showed 276whp 235 n-m

 

Not sure the cams are helping or hurting you. Your doing the right/easy thing which is increasing the boost. Beyond that your going to be spending big dollars for little improvement. Bottom line, you need a blower that can push more then 10psi without exploding. You can expect to max out about 380-400whp with this blower. Mustang dynos read low, so keep that in mind. Once you max out this blower and go back to this same dyno it will likely show about 340whp which isn't really an accurate real world representation but you will get the delta anyway.

 

Injectors are on the small side... if it’s an ap2 your going to have issues with the relay wiring. SOS makes a relay kit that changes the relay itself as well as the wiring go keep pumping the injectors as hard as your going to need to with the additional boost. Either way if your trying to go anywhere near 400hp 1000cc injectors are likely one your future. At 399hp and 75% duty cycle I was suffering from fuel cut at 7500rpm from the relay being overloaded.

if it’s an ap1 you won’t have this issue but the injectors will still need help
