| Headers,....what "specs" did you buy from???
Kev,....
I keep on hearing about the SLP headers that you have to dent the pipe to make it fit, raise the motor & hope it still fits, I'm not into a pry bar against my streering to get a header to sit,....but, the clearence on a '91 Formula,...I don't see a fit anywhere.
Correct me if I'm wrong but, the MAJOR ques on headers, (& not the "shorties" crap), here is;
Which is the easiest to install?
The longer the pipes to the collector, the lower the rpm's which they make a differance ie;
longer the pipes, more torque @ lower rpm's.
The geomatry & physic's, (I know,... spell check is off), of proper header prefomance is beyond the scope of us,....so, how does one make a informative choise on headers, besides,.."which is the easiest to install",.....
Without any "real" info, (pressure ratio of ex-valve to ex-pipe, etc), this is just a, "Holley, Carter, Q-Jet" debate.
The 4 tubes to the collector,..same lenth, (basic),...who takes a tape measure to a set of headers?
How can you measure them on the web?
My intake, cam, heads, etc, dictates that my exhaust profile should be; "x" degree of bend,... @ "y" lenth= ???????,.....
I see no profiles or specs besides;
"the longer the tubes, the lower the rpm range of max torque"
So,...unless we computer design our
own headers to our "specfic" mods, (correct me if I'm wrong), we should be buying headers based on the, "money-to-time", (to get 'em in), ratio.
(BTY,... the sig was just a joke I had to get out of my system but,...the more I started to think about this,.....just had to ask some questions,......& have some fun along the way),....
