welcome to the forum

 

I hear about 8 whp gain fron the pulleys, @12 withe the offroad pipe, and about 15 with a cam gear

 

I got mine from the dealer. Ford Racing UDP for $105.plus it comes with a new belt.No biggie changing if you have access to "air". You need to grind down the plastic cover tho or the belt will rub.

 

I have the FocusSport UDP, its nice and for $110.00 you cant really go wrong. I notice a gain with the low end, which made me happy.

 

Do you know if its really that big of a gain and does it void warranty?

 

I'd like to see a dyno sheet that shows an 8 horse gain at the wheels from a set of pulleys. I find that very hard to believe.

 

I heard there are some pretty big gains after reaserching it

 

I'm pretty sure its more like 4 to 5 HP from the pullies, and 7 HP and 9 lbs torque from the ORP. And someone who bought the Focus Builders Handbook, said it had dyno sheets that confirmed those #'s (I cant remember which forum that guy was on, I think it was MFF). [thumb]

 

If you happen to view focussport Web page you will see that on most performance parts they offer a dyno sheets, so that you can review the dyno results yourself. []

 

the dino says gains of up to 28hp on a Zetec Engine i dunno about all that but I bet it does have gains of around 8hp

 

Anyone know where I can find a dyno sheet showing an 8 horse gain at the wheels from a set of pulleys? I'd like to see it for myself.

I'll check out focussport to see if they have it.

No...cuz you won't find a trustworthy dyno sheet for the zetec showing that kind of gain...unless it is highly modified. It doesn't matter what a company quotes on their webpage...numbers will vary from car to car and from dyno to dyno...not to mention where they are finding that gain (peak, largest gain, at a specific rpm...). Seriously, 4-5 whp is about right in most circumstances. Besides, the 4 or 5 hp is nice, but it is the increased throttle response you really feel when you step on it.

 

i honestly doubt any UDP will gain 8whp on our cars. each manufactured udp will show similar gains on different cars, they are all a same size reduction and weight reduction from stock so numbers shouldnt vary from car to car like with cam gears. other mods shouldnt too directly affect the gains of a udp also. its a good bang for the buck though. not a very expensive mod we're talkin here

To answer your question about voiding your warranty. All the mods you mention will void your warranty so be careful. I would suggest you keep all your factory components and if something does F***k up you just reinstall the factory stuff and tell the dealership I don't know what happend [scratch]

 

Thats what I was wondering about if it voids the warranty because your changing engine components

 

essveetee,

That's where I was headed with this discussion...no one will be able to show me where to find a reliable dyno sheet showing an 8 horse gain at the wheels because one does not exist, and if it does it's been messed with by a manufacturer selling the part to look the way they want it too. I would be suspect of even 4 to 5 at the wheels. Maybe 5 at the engine...but not at the wheels.

Yeah, I hear ya. Basically, it comes down to two things: reduction of polar inertia (mass reduction...and where it is reduced--towards the center or near the edge?) and underdriving. You can only gain so much in these two departments before you are only wasting money.

Yeah my dealer gave me a ton of crap about pullies voiding my warranty

 

Yeah, definitely would void your warrenty. About 8hp gain, highly doubt that. I got maybe 3hp if I'm lucky from it from the last dyno I had.

 

So im guessing yall are saying Don't get pulleys ???

 

I bought a set, but I havent installed them yet. If your worried about the warranty then you shouldnt buy ANY mods because most dealers are going to try to void the warranty no matter what the mod is. But I think they will improve the driving experience!!

 

Im gonna mod the car as some of the mods I know won't void anything like an intake strut bar etc. Im more worried about putting in pulleys and a 65mm throttle body

 

Some dealers cry about aftermarket intakes, too. Mine is one of them.

 

"Vehicle manufacturers have thoroughly investigated the use of torsional vibration dampeners and conclude that their use significantly reduces NVH (noise, vibration and harshness). Furthermore, manufacturer and independent research shows that torsional vibration dampeners are critical to engine life where long-term use is intended. Removing the torsional vibration dampener from an engine can be highly detrimental to its long-term operation!"

just a thought....

 

i have udp's and i wouldnt expect them to get much more than 3 or 4 ponies.
