that kit will not get you 575 hp they over est.the hp level so you will buy it , rpmoutlet does the same thing i got theE kit option it says adds 121 wrhp and 182 rwtq . my car made 490rwhp and 576 rwtq .and thats only after getting eaton ported and a 6lb lower pulley with 20 psi boost. so stock is 390rwhp lets say at another 121 hp is 511rwhp see mine didnt even come close even with ported eaton and 6lb lower s/c pulley.

I'm not really concerned with the numbers, but did you notice an increase in performance with that package?

You can do better putting together your own package. Their 575hp claim is at the crank. So it comes out to about 505rwhp. You can get to 500rwhp quickly with.........
* CAI or RAI intake
* Catback
* Midpipe (X or H)
* Ported Eaton (Stiegeier recommended)
* 16 lbs. of boost (2.93/2.90 upper with 4 lb. lower; 2.76/2.80 upper with 2 lb. lower; 3.1 upper with 6 lb. lower, etc.)
* Tune

Be sure that if you are shooting for 500rwhp that you plan on adding the recommended supporting mods (larger HE, suspension upgrades, etc.). Also plan on upgrading your MAF and fuel pumps. Injectors will be fine at this level, although 60 lb. are not a bad move.

What are your correct mods? I'm not sure what you mean when you say you aren't concerned with the numbers but want to know if performance is increased. I'll assume you either have a stock Cobra or you have basic mods. If that is the case then you will see a big jump in power/torque. And with that jump comes a performance increase. Both on the street and at the track. A stock Cobra can run the quarter mile in the high 12s at 109-112 mph. My car with the above (making 504rwhp) ran the quarter in 11.4 @ 122 mph. That was two years ago.
