Who can make a 1250hp bigger in cfm.
#11
i purchased an APD alcohol custom built 1150 cfm last year and couldn't have been more happy with it. i would not hesitate with either company
$1,600 plus your carb sounds really steep speacially if ya got a $1500 piece to begin with...WOW ! but i guess they are getting it.
my 2 cents

I don't think you need more than 1250 cfms. Maybe a better built carb. Check back with us but Ill bet they set you up with a 1150 to 1250 cfm set up.
If RPMs is what you want:
Big heads
Alum. rods
Lots of spring pressure
and a big stick
is what your looking for.
GOOD LUCK :?

we've ran a 1150 APD on a 565 Big Duke motor that made 1150hp on the dyno.

Maybe I can borrow it to make a pass in my 4link dragster. I always have wondered how a motor from your type of racing would do in dragracing. Probably JUST HAUL ASS!!!
I have a top dragster but only have a .775 lift cam with 250lb spring pressure. Working on consistancey and durability.

Thats where drag and pullin differ. I can car less about consistancy and you guys do. :wink: But we have to make ours pretty stout to take the extreme abuse. Nothing like wfo for 12-20secs and choke it down so it almost kills on ya. This motor of mine is built for the rpm. Gotta love it

carb
just call pat at pro systems, he will tell you what is needed, probably a lot smaller than you think, he built two carbs for me and they were perfect, not even a jet change was needeed. Plus he talks to you like he knows you , and any proplem at the track , call him and he helps right now , I wont ever buy another carb without going thru him, what ever he charges is worth ever dime

I was able to borrow a BIG carb from a fellow truck puller. It has 2.200 throttle blades. He couldnt remember what cfm it was. But it picked up 6hp on top and areas of 10-20 trough the mid-range. So a big carb did help a good amount. This is at the wheel numbers. 740RRWHP which is on my chasis 1070hp.
