Question JET Powr-Flo TB Spacer & a 460????

How about throttle body spacer??????????? Have ordered up a JET Powr-Flo one for my '94 F-250 460. Any body have any knowledge of their perforance value, Good, Bad, Ugly?????????? What info I have gotten is that they make a positive difference in driving speed torque and gas milage.

OK, it is winter here and yesterday it was up to 50 and the sun was out so I got out and installed the darn TB Spacer, was a snap, have not had any time to try it out yet. Will be heading to the hills to snowmobile during the next few weeks, you know mountain roads, 4 wheel drive, etc. So, we will see. 94460

Well!!!!! What happend?
Did you feel the passionate purple weasel of Sales Hype sliding up the muddy.....?
Or did you feel an honest difference?

I would be curious about the fuel milage your 460 gets?
My 77 F-150/460 w/4bbl gets 9 to 11 usually. With a load on it and going up a headwindy mountain pass, can go down to 7 mpg.

What does your 460/FI get?

97/F-150/4.2L/XLT/Canopy. Old boats and motors too. I like the old Fords but I gotta have the features now that I'm old.

Well, first shot into the hills one time so far with two sleds full of gas on the deck, got an honest 5% better gas milage. Torque curve seemed to appear higher, not at the bottom as it was before the TB Spacer. We will see on future trips.

Thumbs down

Sounds like snake oil to me. Most of those "gimicks" do nothing but take your money and convince you mentally that there is a difference.

Waste of money, my feeling.

On my first trip out, as above, was carring half again as much weight as I had previously, pushing it harder and gaining a bunch more altitude, up to the summit of Blewett Pass. Previously, when establishing a base miliage carried half the weight, was traveling only max. 45 MPH and on the level, but gained only a fraction of the altitude I did on the test run. Hope the good results continue, or it's 120 bucks for a chunk of aluminum.

CORRECTION, establishing a base was with one sled full of gas on the deck. First test run was with two sleds full of gas.

biggrin 2nd Test Run

Ok, here is the second run with the TB Spacer, I duplicated the route I used to establish my base miliage, same altitude gain, same amount of 4 wheel drive, same temp., same speed, same load (snowmobile deck-500lb. & 1 Sled with gas-500+lb., you got it 1/2 a ton. I can not believe it, a 20% gain, from 9.00 to 11.33 mi./gal. Well, here is hoping all of this continues.

Smile 3rd Test Run

This was more agressive than how the base miliage was determined, same load though. Was quick elevation gain, 4 wheel drive, some backing up, required lower gears, return trip required 4 wheel drive, 1st gear for braking, too steep to rely on brakes alone, had a 11.2% increase in miliage. At this point I figure the gain will be between 10% and 12%. Low so far is 5%, high 20%. L8R

Smile 4th and last test run

Pedal to the metal up to the summit of Blewett Pass, pushed much harder than before, two sleds full of gas on the deck, (3/4 Ton Load). The miliage was the same as establlished before the Throttle Body Spacer. That is the last test run, I will keep the TB Spacer in the engine. There you all go for what it is worth.
