Default Weldon Pumps?

I am in the market for a good external pump for around 600-700rwhp and have read that the Weldon is about the best. Do I need a 2025, or the 2015? Who has the best pice on them? And lastly, with the Weldon do I need a pump regulator for street use like the Aeromotives do?

Thanks guys!!!!!!

If you don't plan on drastically increasing the horsepower, the 2015 will work great. I don't know if you need a dial a flow controller, I had one when I ran a single 2025 pump, and I needed it to keep the fuel cool while cruising. I would probably recommend you get the Road & Track Combo Kit and be done with it. MadMan can get you a good deal on it, www.madmanandcoracing.com for his number.

That is what I would like to know as I will have 650hp on turbos and say 200hp on nitrous. So 800-900rwhp! I think I need a 2025 but the shop building it said the 2015 is more than good.

I've spoke to weldon on the phone and he ashured me that the 2025 was good for 1250wrhp so I'm thinking that maybe a little to big for your setup.At the same time these pumps are so pricey I'd almost spring for the biggin.The only draw back though
is the more the fuel feeds and returns the hotter it gets.But you can get a volt a boost so the fuel dosen't get to hot,and your pump dosen't always have to work so hard.

I have spoken with Jim Craig over at weldon MANY times, they are a great company. I was looking at the 2025 and he told me it was good till about 1200 horse, but after speaking to him I decided on getting the new 2345, More room to grow, I have a weldon dial a flow, plus the 2345 isnt like the 2035 its not a HOT pump, it can be ran as long as you like
