Porting stock Eaton Stage 4

[cobranb]

Need some input on next mods? 03 cobra with Borla catback, C&L air intake, 2.93 Billetflow pulley with RWTD tune. 448rwhp and 447 ft/lbs torque. Thinking about having my Eaton ported to a stage 4 with throttle body and plenum ported too or Billetflow parts(60lbs injectors and Boost a pump). It will be tune by Pete performance dyno next spring.Will i get 500RWHP with this mods. Also is there any reliability issues with the car after the porting. I go to the track 2 or 3 times a year but its not a race car mostly joy rides.
Thanks for the input guys!!!

I would change your pulley to a 2.76 or 2.8 then you have a good chance at hitting 500rwhp with a stage 4.

If u want 500hp u need a 2.93 upper 4 lower or
2.76 and 2 lower with ported tb and plm also with ported blower,
60# Kb bap And exhaust

You might not need the lower, it depends on the car/tune/Octane available. CA is understandable to need that seing as how all you have is 91, however on 93 you can bump up the timing for more power!

You definitely should be able to hit '500' on a 93 octane tune with a 2.80/2.76 upper (stock lower). I hit 504rwhp with a 2.80 upper only, and that was with a Stage 1 port. That said, I would recommend a 2.90/2.93 upper and a 4 lb. lower. Many run a 2.80/2.76 upper with the 4 lb. lower. A ported blower is more efficient and can better handle the increased boost.

Stg. IV Eaton, Pumpgas and a .1 sec. reduction in 60' time will net a 10 sec. pass.

i hit 500 with just a stage iv port, 2.76 pulley, exhaust and intake. I plan on putting 60lb injectors and a single blade and see what he can get out of it the second time around
