  • It tried to inhale the fan :)

  • kabooom!!! Edelboom!!!

  • turn up the pressure

  • I just got the edelbrock 90mm mass air flow and filter,it was on back order for a few month's,now I am running 470rwhp with the 7lb pulley ,with comp cams,jba header's,pypes high flow cats,and magnapack muffler's.It's a beast for an automatic,it smokesem at 40 mph.My mechanic at the speed shop said anything close to 500 at the wheels and im taking a huge risk of blowing the bottom end out,is this true ???

  • @GMurphSC06GT try upgrading the fuel system with the GT500 fuel system....the car should be fine up to 500 hp

  • Does this supercharger have ay Whine to it ??

  • good low boost for engine saftey

  • I have done some modifications and did another dyno run. With the 7lb pulley I am now pulling 446 rwhp/417fptq which is calculated to 525hp at the crank. This is with GT500 fuel system upgrades and JBA headers.

  • Thats more like it, wicked

  • @tomredfiregt

    When you got the 7lb pulley you had to upgrade the fuel system? How much were those components and what did it consist of? I have a 09 gt with JBA T/C coated headers,diablo sport tune/airaid CAI (set up for offroad) 3' magnaflow cat-back w/magnapacks. I have this kit on order but I think the 5lb pulley isn't going to be enough for me. Im also going to switch to JBA long tubes and off road x when its compleated, cant wait!

  • @texasbradley Yes, I upgraded to the GT500 fuel pumps, it is 2 pumps each with their own driver. Better than the Vortech doubled up pump solution.

  • That alright 390rwhp but my question is why do all You Tube videos show dynoing with the hood open? So I take it we all drive down the street with the hood open!

    To get real HP numbers hood should always be closed. Dyno shops have proven up tp a 6hp diff between open & closed hood on the dyno's. so tune your cars with hood closed.

  • The dyno requires that they tap into the vacuum line so that may be tricky with the hood closed. I am sure you can also say that driving gives wind resistance too so it isn't going to be a perfect representation.

  • 390hp thats it?? though this kit made 466?

  • 466 crank. some kits put out much more power depending on supporting mods and software.

  • 466 at the crank...advertisements always show crank horsepower unless it specifically says RWHP

  • oh man, thats nice and quiet. how complicated is it to install one?

  • JBA Headers, Magnaflow Cat-Back exhaust. The blower comes with 41lb injectors and colder spark plugs.

  • Any other mods besides the blower? I'm assuming you were using the tune provided with the kit right?
