X pipe H pipe or side by side
Not too many in racing is making more power with small blocks than NASCAR. Those guys have pretty much perfected making max HP and Tq. They have to make power from 6500-9200 Rpms. They run X pipes. They have long since gotten away from H pipes. Seems like if that was masking another problem they would have figured it out by now.
Ok when YOU test and do R&D like nascar then I would agree. I can't tell you how many times on the dyno I have taken both styles off and made power. And at the tack.
If, and it is a big IF, you are testing cam/cylinder head/induction/exhaust then you MIGHT find power in a very narrow rpm.
I am not the only guy out there testing this stuff, and finding 99% of the results outright lies. Joe Sherman, a very well respected engine builder who worked with Edelbrock has been dyno testing this stuff way before I started. Our results, REAL WORLD RESULTS agree.
Go join speedtalk.com and then search the site for x and h pipe threads. And you will see the guys who love x and h pipes and tri-y headers and merge collectors (another joke for 99.95% of us) are the same ones who get to spend 100k in development with the latest testing equipment you can buy. All in a computer controlled atmosphere, both the dyno room and flow bench room.
Do the research before you spend your money. You can spend less money and get more than to mess with that stuff.
But some guys are slow learners, or have handicapped combinations. I suggest fixing the combo and then be prepared to spend big $$$$$$$ to do and get reliable testing.
Flame on.
