Anyone have any idea where to get the spring that raises FP in the Fass 150. You have to go thru a vendor and I didnt get mine thru a Fass listed vendor. I want to try and see how my dual pumps respond to a little more FP, cause I want to see over 800hp at my next Dyno event but I dont want to buy another pump. TIA, Ryan.

 

DPP or one of there dealers can get it for you. Do you have the 150/150 or 150/95, and how much pressure are you looking to get?

 

Well I have dual pumps and the top one is a D-max pump and I have heard they dont like raised pressure. If they have some lighter springs to get 20-30 range maybe it would help, im not sure. I just dont want to have a FP issue leave me short when I dyno at Claremont.

Oh I have the 150/150. Thanks,Ryan.

 

The 150/150 is limited on its pressure output to about 25psi. Anything above that will be pretty hard on the 150 motor. The 150/95 and 200 models can do more pressure just not the 150/150.

I would give DPP a shout though, I saw they have a new pump with adjustable regulator mounted on it, so maybe things are different now.
