Got a few questions, all for my 460 factory motor with 80k on it.

1. Does the Tornado Performance Add-On really work for this motor. My vol. fire dept just bought one for our ambulance which has a carburated 460ci. I guess a sales man sold them on the idea and now they are ranting and raving about it.

2.How decent is the factory installed exaust system. I dunno if the one on my truck is factory but it has two 2.5" pipes running from each side right down to the muffer than a 3" pipe running the rest of the way to the back. Is this a good system to stay with or what would be better. I see putting on headers in the future and might change the exaust system if its flawed.

3. Anything faulty on these motors, I know the oil pan gasket is going but it looks almost like the motor needs to be jacked up to about a foot above its current position just to get to it.

 

Unless yours a Chevy, and that it will work on a Ford....Their website didn't mention Fords. On another note, years ago I seen one of their ads on TV, it was impressive and it made sense. I have never tried nor tested one but it seems logical that the concept would work well. Makes me wonder why has'nt the big Auto industry hasn't come up with a version of their own? ESp now that gas is nearly the $2.00 mark....and you wonder why does it cost so much to unlock your auto.....

 

They make them for all makes and models, I just googled and used the first link I hit for a description. The auto makers are in the bed with fuel companies, that why it takes years to push a non-gas car through and why the big fuel saver models don't last (remember the 3 cyl Geo, 45+mpg). To actively try to save gas and bite the hand that feeds them, would be disasterous.

 

A friend of mine had a tornado in his ranger. He & I really didnt think it did enough to pay for itself.. I think it was like $50 or so..

btw.. Diesels were designed to run on corn oil. They will run on corn oil, but guess what? No one knows about it, and it produces virtually no emissions. Guess what, no one is letting that secret out! Imagine how independant we would be from OIL companies, and how it would pay to be a farmer again.

 

I don't know about the tornado, but I do agree with Locknkey.. the theory is sound but does it justify $50-$60 ???

Jade, have you tried upgrading to a K&N Air filter yet??? The better it can breathe the better it runs....

As far as exaust goes... I am a firm believer in cutting the pipe right in front of the cats and running straight to glasspacks (If you install them backwards they dont muffle...HEE HEE HEE...) and straight out the back.....

LOUN AND PROUD BABY>>>> EMISSIONS BE DAMNED!!!!

but then again, I dont live in CA... I live in nowhere Iowa where emissions don't exist.

 

I should have said this is a cat-less system from the factory, only pipe and mufflers. I also live in Iowa, gotta love their emission laws, or lack of.

 

tornado and k&n are both a scam. if k&n made so much power, than why does the factory pass them over? horsepower wars are on, and every one of them counts. tornado,farting in your air cleaner will give more horsepower while excellerating. i have see those damn tornados cause more drivability problems in FI vehicles than anything. do you know how bad it fukjhfhdw's up a MAF sesor when air is swirling around like a fart in an old mans intestinal track? bad really bad. k&ns, flow nice, but at the cost of dust intrusion. the media is larger(allows more air through), but look at you t body on a 100 miles. nasty huh, thats dust my freind. and it does wondefull thing to you rings, and cylinder walls, as well as to the air bleeds, and venturies in you carb. imagine what it will do to a MAF sensor, or iac, or even a maf. bad idea. the exhaust was a bit of trouble, has a tendency to crack manifolds from excessive heat kept in the head pipes. dual 2.25 pipes will do you good in the low end and still give you top end grunt, 2.5 and you will lose alot of you bottom end power. to get the oil pan off. you really should save yourself the hassle and just pull the motor. i can pull, replace the pan gasket, and stab the motor in and have it running in 6 hours. an average diy'r can easily do it in a weekend, and even quicker with a buddys help, but NO BEER! just kidding, let you freind drink, and comment on your workmanship, and when he pass's out paint his finger nails, and shave his head..

about every month someone asks about the tornado. They are garbage. Think about it. This magic thing swirls air without producing a reduction in flow. OK I can buy that lie. But lets say you have this tornado of air rushing into you motor. What do you think will happen next? It will go thru your carb and be more of a mess then it was in the first place.

look up biofuel on the web. It is popular among some boating circles. I think it cost about $.40 a gallon?

 

i have done many bio-fuel conversions in the dodge diesel. infact the cetane(octane for diesels) is actually higher with recycled cooking oil then in was for the diesel we bought at the local gas station. and it will run for a dit'r about .20 a gallon. thanks for agrreing with me on the tornado, it has caused some good drivability problems in the past before i discovered it mounted in the intake tubes(ford 460 fi).. Kurt

 

actually somewhere here in colorado they just opened up a biodeisel "gas" station,i'll have to look, it was in the paper

 

They stuff like that is popping up. which is good.

 

I have run K+N for years. Keep it oiled and it will work wonderfully. The exhaust I agree with the rest of the gallery out here. Dual no cats.

 

So is my exhaust ok the way it is for performance or is this restricting it in some way? Also what little add ons can I do to improve the engine, even slightly. It just got new 8mm plug wires and Champion Copper Plus plugs gapped to .046" (range was .042-.046 on the sticker). The cap and rotor are newer, a lot cleaner than the rest of the motor. So 2 more questions.

1. How hard is it to rebuild a carb or do anything to improve it? I think this has the holly 4brl, dunno the exact model though. During a cold start, I pump it twice, start it and it stalls after 5 seconds, repeat this twice then it will idle fine. First 20 minutes of operation, if I accelerate all the way (floor it) from a stop, it will hesitate and backfire then run fine if I let up on the pedal. Still does it when warm but without the backfiring, just a lot of hesitation. Are these motors usually like this from a cold start? It usually starts after the 2-3 cranks from sitting almost a week.

2. How much are exhaust headers (approx. of course) and where can they be located at? Will these help in the short or long run on performance and gas mileage or are they an added waste. A few Ford owners locally said that the 460ci had an exhaust restriction problem with the manifolds.


Thanx!

 

Sounds like you need to check you timing, and you probably need to rebuild your carb. Myself, personally, would swap a Edelbrock 750 on and be done. Sounds like maybe you powervalve is blown (not to familar with holleys).

Headers will run any where from $99 to $600. Headers will add power, and increace gas mileage, but I couldn't say how much though. They sound better, for sure.

 

The motor has 80k so I figured the carb was shot. I'm getting a timing light next week so I can figure out the position of the time. How much does the Edelbrock 750 cost?
