pump upgrade
Guys
I guess I'm going to have to upgrade the stock pump to provide a little piece of mind for my H/C engine with N2O. What is a good choice to support 550rwhp? (150hp N2O)
Who sells what, at the best prices?

The racetronix set up should do it. I belive it is a Walbro 255 pump, will provide enough fuel. If you have a dry shot, you may want to think about upgrading the injectors soon.

Depends on the year of car, 01-02Z's should handle the shot fuel wise, 03-04Z's need some sort of pump or boost-a-pump, like the MSD. Beware of the 150hp shot on a stock bottom end, even if pulling timing

Thanks for the replies guys, I have the Racetronic setup on the way; It should be here Thursday, will try to get it in over the weekend. Going to get it dyno tuned the 11th.
I usually keep the 125hp pills in it for the street, but want it safe (and tuned) for any track time. Although I have no intention of pushing my luck, some of the F body guys on the LS1 tech site claim to be running 175-200 shots on their H/C cars with stock botom ends!
