not at all too "scientific", i just figured if you're really that paranoid and "need" the benefit of the UDPs that it would be the solution...

on that note, after i made that post, i started searching, and it's hard as hell to find gears for our oil pumps... would it be those of a cobra? or is this something that ford made specific for each 4v mod motor?

i don't have the instructions in front of me, nor do i plan on doing it, but i'm the type of person that if i was going to go with UDPs and wanted to be safe, i'd go with the oil pump gears...

also, i don't care how long/difficult something is as long as it gets done...

also, just out of curiosity, do you try to be a **** in every post you make or is it just a coincidence?

Re: Under Drive Pulleys..and the problems they cause.

I don't think there is ever gonna be a solid yes or no for this, for as many people who say NO, there is just as many people who who say YES.

Billet oil pumps are around 350-400 depending on where you buy them.

If you want every last horsepower and dont want UDP's get an electric water pump....

found some for a cobra for $282 (pre-shipping), and that's why i was asking because i didn't think that was a terrible price and after seeing that, i definitely think that's not a bad price...

Glass houses, bubba!

To be perfectly honest with you, ANYONE stupid enough to replace an oilpump JUST TO BE ABLE TO RUN A UD DAMPNER, needs to have their head examined!

It's ok dude. You made a comment before realizing exactly how friggin complicated it was. Don't get all butthurt when you get called on it. You're only 18. Believe me! You're gonna make a whole lot more silly statements in your life and the sooner you learn to live with that fact the easier your life will be.
i did not say it was smart to do that, just said it would be the ONLY SMART WAY TO DO IT...

and i, in no way, thought it would be a simple upgrade, i honestly don't care... most people say headers are hard, and i plan on doing that, so difficulty isn't really an issue with me...

Re: Under Drive Pulleys..and the problems they cause.

udp = broken oil pump at 7000 rpm been their done that . and ford esp. sucks new motor $ 8000. and no under drive pulleys stock oil is junk. never again.

I'm not trying to be a jerk, but i couldn't understand what you just posted.

So your oil pump shattered at 7krpm? Highly Conceivable with large load and increased amplification.
New motors from ford range within 8k? Woah..Thats not right!

Stock oil pumps are junk? I couldn't agree with you more!

If it shattered at 7k rpm that there is a more reasonable and solid explanation as to why it would fail. Vibrations and amplitude would've increased dramatically as opposed to a DD at 3.5K rpm on highway or city drive.
Oh well...

Re: Under Drive Pulleys..and the problems they cause.

what i was trying to say is that my oil pump came apart at 7000 rpm and i had udp. So i took in to the dealer for some warr. work they decline my claim
with all that b.s i had to deal with from the dealer i just took my truck into the dealer donahoo ford in baltimore md and got all stuff and went back home rebuild my self, now it a 310ci 11.0 to1 n/a motor kooks headers canton oil pan the list go's on the short of it is the oil pump is a weak link .
So a $55 dollar oil pump trash's $6000 motor if replace with a OEM, i would have loved to got a used motor and put the rest of the money towards the payments

Re: Under Drive Pulleys..and the problems they cause.

If you are thinking about risking your engine
to gain MAYBE 2 or 3HP, think again.
Evidently some people think they know more than Al Papitto,
and most other modular engine builders.
You'll gain more from an Aluminum driveshaft and flywheel.

Good pulley options

March sells large diameter PS pump and alternator pulleys. When used with the stock dampener they should free up a few hp without compromising the oil pump gears.

I gained 11rwhp with a March Fluid Dampener. I dunno if it would have resulte in an oil pump failure or not.

Re: Under Drive Pulleys..and the problems they cause.

The March website specifically states
they are not to be used on a Mach 1, or don't fit a Mach 1.
I called a while back and asked why, and they had no answer.
The fluid damper type is probably less risk than the elastomer type.

Re: Under Drive Pulleys..and the problems they cause.

There was a mid season change (2001) with pulley alignment that applies to all late 2001 Cobras and 03/04 Mach's. I thought this was the limitation as Fluidamper didnt make one for the late cars. At least, that's my understanding. Do they make a version for each or are you saying the single version they sell actually applies to the later style water pump and pulley alignment, or both?

Re: Under Drive Pulleys..and the problems they cause.

Anytime you change your cars from stock trim you are asking for more troubles. The more power you add the more things are going to break and the more issues your going to have. You just have to ask yourself if everything your doing is worth it. If you race your car all the time anyway its going to break at some point and pointing fingers at the underdrive pulleys along I think is hard to prove. Just my 2 cents. Good post.

Re: Under Drive Pulleys..and the problems they cause.

Here we go again .. .I will just leave it with what Sean Hyland says..
"There seem to be increased instances of oil pump failure when Some brands of underdrive pulley kits are used. I believe this is due to inadequate damping with the reduced diameter harmonic balancer provided .Steeda and ASP both make pulley sets that include a built- in Harmonic Balancer ." Improper installation using the old bolt and wrong torque have been factors too.

I installed the Steeda ones on my car and have had no problems peroid.Gained 10hp/12tq with the install . I think that the failures are mostly due to the 5- speed cars that rev higher than the auto . Combine that with the missed shift ,over -rev factor with inferior pulley sets that could be a problem.

Those pullies have nothing to do with the harmonic damper.

Re: Under Drive Pulleys..and the problems they cause.

I have the steeda crank pulley on my 5 speed Mach and your telling me its going to trash my motor? This sound like something Steeda should cover is it happens. Where should I get a better oil pump from?

Unhappy Re: Under Drive Pulleys..and the problems they cause.

I'm having Steeda install their under-drive pulley because the original Ford harmonic dampener failed and is rubbing against the timing chain cover. This is on a 2003 Mach1 5-speeder with 39K miles, never raced. Ford quality for you.

Anyway, Steeda claims that they have not heard or read from any Steeda customer that OEM an oil pump on the Mach1 was affected by the replacement of the harmonic dampener with their own under-drive pulley. It's difficult to decide who is right, but at this point since the Mach is out of warranty, I might as well try this one. And if the oil pump fails, it'll be another crucial moment to ponder about Ford's quality and decide if I'll ever buy again their "quality" products.
