I stock & recommend the Racetronix kit.

If you plan much over 550-600rwhp in the near future, I can set you up with a custom dual pump kit... better safe than sorry.

Let me know if I can help.

i keep trying to find what the stock pump will support so you are good so far at 500 rwhp? I hear anywhere from 400 to 450 to 500 if your lucky. I figure im making 420 to the wheels and want to spray a 75 shot at a upcoming dyno day but dont feel like changing out my pump. I tried a 50 shot on the street and was a steady 12.2 on the wideband so i guess its good.

Eventually am gonna get a racetronix kit but like i said dont feel like messing with the car anymore this year lol... already have done a converter swap, cam swap, spring swap, and nitrous install in the last 2 months..

12.2 would be too lean for me.

The Racetronix are a direct fit replacement with complete wire harness. New Era are just basic Walbro pump that require cutting and do NOT fit your factory bucket and jet pump.
