HP limit for imco exhaust
I am just finishing up my 509 c.i sidemount whipple engine built. Im shooting for 700-750hp. I currently have some older imco powerflow exhaust. Will this exhaust support this HP? or do I have to upgrade to the powerflow plus or tube headers? Thanks in advance for the help
|
I had the same in the past with 800 SC hp and no problems if you have the xtra money to burn I would get me a set of cmi headers maybe get extra 2mph for about $3,000 plus
|
The exhaust will be fine an SC'd engine. I don't think you'll be able to make thta kind of HP with a sidemount whipple though.

whipple horsepower
I am not sure why you could not make that horsepower with a 509 with that whipple,i have a 509 with some big heads and it made 690hp n/a,i would think it should be at least that power with that blower.
|
At what rpm did it make 690 HP ???
|
:popcorn:
|
Does the side mount have a innercooler????
|
Just picked up my engines from Tyler Crockett last week 454 mags with side mount whipples (with intercoolers) 712 hp @5300 rpms 815 ft pounds of torque @3500 rpms fine tuning to be done after break in and installed in the boat:)
|
yes it has a cupernickel intercool. hey past due, what kind of exhaust are you running? and do you know your cam specs? are your 454's stock or built? thanks
|
