How much power will it take to get an 06 382 to do 80? Will 575hp mills do it?

My previous 2002 382 ran 80 any day, 82-83 most days....86 on it's best day. (actually ran 98 when first built with blowers but I took them off)

630 hp/700 tq fully dressed on a dyno. Regular length XR's, no boxes. 32P Bravos (86 with 30P Bravos)


My guess is 575's will do it with a light load and perfect conditions.....unless you change the pulley and add an intercooler!!!

my neighbor has one with 575's....77ish in the summer with fuel and people and in freshwater.....will touch 80 light and right....1:50 bravo xr's with 28 maximus lab props

Friend is looking to build some NA motors that will take his 382 to 80.

MrSneakAttack

i would go with 650's.....

Is this the guy starting with 496's.......swap them for a set of Raylar 600HO's and he should be there.

A few years back, 575's with shorties and boxes, prior inter coolers, pulley and computer change, I hit 82.3 GPS on 63 degree day in a 2' chop. Once it warms up, forget it. If you want to consistently hit 80, I'd think 650 hp would do it.

I have the '99 Poker Run Special. 650 h.p. with XR drives and nosecones on Stellings extention boxes with unlabbed 28 bravo props turning in:

Sure is. He wants nothing to do with computer motors anymore. Less is more in our book. Thinking some 502's with Aluminum heads around 9:1 or even short deck 540's. Something in the 5600rpm WOT range.

I don't blame him. I posted my numbers earlier....these were 500EFI's turned into 540's (with heads, cam, 9.75 compression, TB and intake mods). Looked stock, didn't sound like it at all!!!! Mark Boos did the dyno work and commented I was restricting airflow. He thought I could have made about 35hp more with a good carb/intake.
