Vortech EFI Maxflow Power Pak?
 

Anyone have any experience with Vortech's Maxflow EFI power pak for 503 EFI engines? This set up consists of high flow flame arrester, MSD ignition box, adjustable fuel regulator and reprogrammed ECU. Any info would be appreciated.
Thanks

503,,, whats a 503 !!??? ( sorry, couldnt resist !! ) several people have had them,,, about $1,000,,, most gain about 1-3 MPH, report better midrange acceleration and a cleaner transon.

does vortech have a website??

rslick, put the kit from az speed and marine on my 1998 26 sonic with 502efi(similar to vortech kit ) and gained 2mph top end.(set adj fuel reg to 42psi and adv. timing from 8deg to 10 deg.)
went from a 23p mirage plus labbed 5000rpm wot to a 24p bravo 1 at 4850 wot and gained 2mph . biggest difference is at 4,000 rpm the 24p bravo 1 was running 4-5mph faster than the 23p! plan on labbing the 24p to get my rpms up and hopefully will get some more top end speed . thinking of adding imco exhaust to this set up but don't know if its worth the $$$.

26 Sonic,

Definately go for the exhaust. You wont see much of a performance gain, but it is worth it just to get rid of the Merc. stuff. Personnaly, I went with Gil Exhaust. I like the idea of having the by-pass hoses rather than having the water flowing through the riser gaskets. It is worth it just for the peace of mind.

rslick,
I have the B&M Smartcharge stage II that I dont need since I installed my Procharger. Its the same kit, flame arrestor, ecu, ignition box and regulator, I think the new kits by Vortech and Arizona Speed & Marine reprogram your existing ecu. Email me if you are interested, I will take $500!
