A car strapped down on a dyno will not act the same on the street. Like i said before, dynos are great for wide open stuff but, fuel in the carb moves around alot on the street and will affect things that you won't see when it's strapped down. We made 740rwhp with a blow-thru set up and it drove better than stock efi.
