The SVT focus pump is a 255lph pump it's a direct swap and will support you on a 150 shot, it's $230 from lethal performance. I have a link to the wiring upgrade on my PC at home I'll post up the link later. If you want google FPDM wiring upgrade. You basicly run a bigger wire from the FPDM to your pump drop the pumps duty cycle so it will support more power.

Also what et's are you getting out of yours? I'm spraying a 175 shot and I'making 486/540.

I don't recall.. I thought I had those graphs.. the number that comes to my head are 245.. but that was thru a C4 with a 4500 stall..it now has a T56..

I haven't taken it back to the track since summer has hit and its 110+ outside.. but the best et before the tank.. with the surge and the lean spike which is worse on a stick car cause you let off the sauce during shifts was a 11.30, on the motor was a 12.60

the runs with the tank.. I only did two as I had to get the car off the Dyno for a paying customer.. the first one did something funny.. but it was the first time running the tank and i believe there was a air pocket in the fuel line.. cause after 2 bottles it hasn't done it since.. the first one peak was.. 444/518 and the second was 430/546.. and these are dynojet number with 3 for smoothing and SAE

thanks, im stuck on whether to go with the SVT focus pump or the Aeromotive stealth 340. i assume the focus pump is easier to install but the Aeromotive pump will support more mods better down the road....

my vote is the aeromotive or the gt super car pump.. IMPO the focus pump is overrated and seems to be the same pump in the 05+ mustang GTs..

At least thats from my research on the internet.. until someone actually does a back to back flow test.. why can't the magazines do something like this??
