HY would choke it. The hy just ain't good for anything.
budget twins? does that exist? after the hours of fitting and installing, then tuning and the intitial cost, it just don't add up IMO. Been there done that. used to own PDR towing twins. HX35/HT3B
for under 700 on fuel, i don't see twins as cost effective. They do have their place over 700 IMO since its hard to do that well with a single.
GREAT looking setup! What are you using for the bottom turbo?Depends on your budget the change to twins cost me around 500. for the primary and piping clamps and hoses home made but rant they all.I built a turbo sheild for the top and insalled it hears a pic of it.
