installed riffraff frx hpx
 

just thought id let everyone know how the install went on riffraff diesel's frx and hpx. the hpx was simple took about 15 minutes and 50 bucks for a nice stainless steel crossover tube. the frx gave me trouble only because i dropped the fitting behind the ac compressor bracket and ended up taking the compressor off to get the fitting in with my big hands. i put the 67-70 psi spring in the housing and after all was said and done it does run very nicely and think it did help out a bit for the 220 i spent on the two. i hope this will be enough to support some stage 2 injectors in the future.

Did you notice any performance improvements. Or is it more insurance, then a power adder? Just wondering because I am interested in doing these mods as well.

well there is no seat of the pants feel to it im sure it probably increases a few horsepower, but it does run alot smoother at low and high rpms but i just did it for more peace of mind than anything.
