It's becoming old hat going past the 240+whp .... figure your favorite correction factor to make your BHP numbers.... one thing we know at RMW..... cars fade quickly in the rear view mirrors
Many "talk" about these numbers..... How many actually prove them and then on the track?
this car had 66,000 miles on the clock
15% pulley, CAI, aftermarket air to air intercooler, RMW cylinder head and exhaust.....
we have one stage of cylinder head................FAST.... no need for mulitple stages, they cost the same to make and anyone telling you different is pulling a fast one on you
what you get with each one of our heads is brand new bronze guides custom made for our heads. Why? because the stock ones are cast junk and will go south on you in heavy duty situations.... We carry only the BEST valvetrain... no skimping here...
Black Nitrided stainless steel valves (inconel available) titanium retainers, dual valvesprings, special locks and keepers... don't be fooled into inferior parts as many of the triple groove type valves drop valves on the track. Ask you manufacture what they use and have them prove to you what is on the head.
