put a down draft intake on 300 promax

[malexie]

The downdraft is 30-35 HP better, OP has two .. so if you want to throw away 60-70 HP, using mostly parts off of the junk pile or E-bay, be my guest ...

When you buzz a 3.0 or 3.2 up to 9200 RPM ... do me a quid-pro-quo and shoot a video of it ...

This race was at DSRA Mt. Pleasant, TX last year. We both have 3.6L. Jacob turn 9300 and I turn 9200.
I the finals he beat me 2 out of 3.

There's no dot in the middle of youtube ( youtu.be )

When removed .. this is what Google / Youtube put at the top of the list for the addy you gave ..

So which one of you is Eddie , and which is Mr. Robinson ..

In all seriousness, putting a downdraft / external injector deal on an early or late model block is a fairly inexpensive way to open the door to power and reliability. Which is what 99% of people are looking for. Most are not looking to run the last couple hundred feet after the split, 2200 RPM past the point of peak power. Just as your not lookin to put in at Palm Beach and check-in at the Bahamian customs building on west end ..

Chaz = thinkin, lots of downdrafts made that little jaunt .. slides, not so much ..

Still working on a better, less expensive billet piece for 2020 :

i've got an early(1999) promax i'm going to be rebuilding soon. I've been intrigued with this downdraft setup ever since i got the 3.0. It has a slide front, Brucato intake, lighted flywheel and flashed Ecm(s) on it now. I ran it on my Gambler bass boat last year, but it's tired and needs tightening up. I would like to know more about what it will take to get in on changing over to this set up in the near future.

He did ask if it's worth it. At 6200 rpm's leave it alone. Now if he wants 9200 rpm's I would straighten out the air even more.

what u running for ignition/fuel electrics,,,,,260/300 style or what

[powerabout]

260 is cd and batch fire
280 inductive and?
What differences in the 3.0 engines?
Ign? Batch fire and sequential which you need for smooth idle on crankcase imj.

hey Marty, what gear ratio do you run on your 3L

Dunno, I installed a handful of 3 lite svs on bass and checkmate type boats. The gains over the box were impressive even on stock limiters. Wish they were still available readily, I could probably do another 5-6 more.

Power performance engineering makes one for the older 3 liters. Very similar to the Brucato. I recently bought two of them. Very nice piece.
