draw straw compared to stock ???

[Graphic Man]

i run the RASP set-up with the stock intake line, and it holds 14-15 psi at WOT and has never felt like it was running out of fuel.....is it worth going to a 1/2 or 5/8 draw straw ?.....i know i have good PSI but is the volume there that i need for my set-up ??

i have dynoed 623hp but i think i have hit a wall and i am trying to figure out why

Thanks

I changed mine out and there was a big difference in size.
Is it going to change your numbers ? I dunno about that. I would say if it does it probably wouldn't be by much.

yeah i agree 1/4 OD compared to 1/2 or 5/8 is a big difference

anyone else seen any difference in going to a larger size?

Buddy of mine went from stock to the draw straw and didn't pick up any power, torque, pressure, or difference in pressure readings. I wouldn't waste your money on it. He dynos 590-600hp and runs a FASS 150.
