Re: Performance help
anything flow better than stock.
summits heads iirc are rebadged vortech heads...
mind you vortech is still and emission head as well iirc
peak flow is one thing avg flow is another. yes vortech have a high peak air flow. both dart and world have a high/flater curve than vortech... kinda like which motor would want peakhp of 525 avg hp 450 or peak 500 avg 475? hope that makes sense
and make more power on a same setup than vortech
IMHO i would take a pair of ~180cc s/r torquers or iron eagles over vortechs any day
got to pay to play and you get what you pay for....
