Default Walbro pump

I was wondering if all walbro 255 pumps are the same. Reason being I bought a racetronics pump with a hot wire kit so I wouldn't loose as much pressure when I hit the nitrous (200 off the rail through a plate) but I don't see where I need a new pump just the hot wire kit on my current walbro 255? What do you guys think Keep my pump and put the hot wire kit on it or put the racetronics on it with the hit wire kit

You might be losing pressure also because your current pump is getting long in the tooth. If it is 3+ years old, you should just go ahead and replace it along with the new hotwire kit

The Racetronix kit for 4th gen F-bodies comes with a Walbro GSS340 (255 lph) pump. Racetronix says something about it not being a standard pump, but the ones I have purchased seemed to be normal Walbro GSS340's.

I have installed two of these kits on my cars. As you will see, Racetronix maintains that this kit (with hotwire) can support up to 600RWHP. I have one in a 500 wheel NA setup and another that is coupled with a T-rex BAP in a Procharged car that is 546 wheel and both handle those power levels just fine.

The Racetronix difference is that it is modified for the factory venturi system to retain the functionality of the fuel bucket.
