PS having said that, there is NO WAY the Qjet will keep up with my done 850 Holley at the track. Not even a contest. One has two big fuel bowls, one has ONE medium sized one. It would take a pretty sophisticated pusher type fuel system for the Qjet to get the BSFC to max out Mark's engine to its potential. Again, Qjet is just for long hauls, which is primary duty for this horse. I already have two feed lines and two spacers made up, one Qjet, one big holley.
600HP from a Qjet requires a race fuel system, something I will not need, nor want due to the drone of an electric pump. Its a resto by gosh!
Which hopefully pulls a little " walk softly and carry a big stick" at the track once in a while.
The Holley is for the track, MAX EFFORT, HENCE my original question on boosters. I know my big Holley will support near 120 mph with nothing more than a Carter NASCAR mech pump. ( [email protected]
to be precise), and it seems like it wont gain ET, in any meaningful way, by replacing the downlegs it has now according to y'all.
PS, I am not familiar with dyno pulls, never having experienced one, but I suspect you dont hold WOT for 10-12 seconds like you do at the track. Therefore, whatever the Qjet "prints" on the dyno sheet, that's not how it'd carry for another 5-8 seconds, to wit, its not how it'd perform on a full 1/4 mile run I'd guess. Not without the aforementioned "pusher" high volume, low pressure fuel system, which wont happen here. Not yet anyway.
