Udp only help above 4000 or 4500 rpms. TB would help throttle response sooner than udp kick in. I got steeds udp but rarely take my car above 4000 rpms. But I got em new for $71 on eBay. If u go with udps, watch eBay.

Got about 4 RWHP and ever little bit of RWHP you can get out of your motor is worth the money IMHO

Seriously you dyno'd after just a TB install?
If so what RPM or range did you realize this gain?
Curious now..

Unless you have enough mods that your sucking more air to your motor then your stock throttle body can handle, a throttle body wont do anything. It can actually hurt performance because air doesnt move as fast through the wider space if it is wider then you intake anyways.

That's a deal! I have a bone stock internal and my mods are stated in my signature. Nothing that would really help the flow drastically

Under Drive Pulleys

---------- Post added at 02:38 PM ---------- Previous post was at 02:36 PM ----------

Under drive pulleys are a waste, when I had my car dynoed the speed shop took my under drive pulleys off and put my stock ones back on!

Get the throttle body!

Ye that's why I got em. Just keep watching and you'll find a set for cheap. The money u save on them is a gd start for TB mod fund. It takes time unless your filthy rich lol.

Underdrive Pulleys are a universally accepted good modification, I dont know what happened with yours White Cobra. Less power to accescories=more power tp the wheels. Just like using your AC draws power.

I think the problem with me was a cooling issue , the UD water pump pulley is bigger so I think that's why they switched me back to stock!!

I just used my steeda crank pulley. They advertised them for 96-01. Well they were for 01-04. So I used crank and bought smaller belt.

Could you guys feel any difference in butt dyno or fuel mileage? I think imgoing with a udp set that has multiple, instead of just the crank

UFOs come in 3 pulleys. Some come in 2, crank+alt. The only reason I only used just crank was cause they were wrong year. Ford changed water pump pulley in 01. So it was that or nothing. Ill eventually put others on. I just have to get right water pump pulley. Its prob going to b awhile lol.

PS. Stay clear of the piggyback style. I've read lots of bad stories.

UDP work for sure. I, personally, am skeptical of them. I have read stories where cars have had cooling issues due to the water pump pulley, battery issues from the alternator pulley, and steering system failure from the power steering pulleys. Now with that said guys on here run em with out problems. So are they a good up grade? On a budget, sure. Are there some risks? Yes. Will it affect your car? Maybe not. I don't think for how little it does justifies the POSSIBLE (yes i said possible)effects it could have on your accessories. With TB, from what I hear you either need a ported intake matched with a aftermarket exhaust or a hotter cam for a bigger TB to make any measurable difference. Anyway, my 2bits

I haven't done anything internally so a TB would be useless I guess

They don't sell just crank. Piggyback uses your stock crank pulley. It attaches to it, making it a piggyback. You want a steeda or bbk. Bbk makes both so read up. Google piggyback pulleys and read up. I'm not one to tell someone to buy something. You can read and u can decide.

I never seen bbk v6 ones but a tb isn't worth the money. Also pulleys are a ok mind but don't add a lot of hp. Look into gears,exhaust,intake,windstar intake

I agree. Although bolt ons don't really add a lot anyway, you'd get better gains from the above list. I think the first upgrade everyone should get is a tuner. I wish I had saved up for one instead of buyin a bunch if little stuff

Seriously you dyno'd after just a TB install?
If so what RPM or range did you realize this gain?
Curious now..[/QUOTE]

Never said I installed a TB you need to learn to READ But I did re-dyno after the intake spacer and there was a nice increase I'd post the increase for you But you'd probally misunderstand that as well
UDP is a good for fuel mileage increase as well as a bit of power

I'd like to see the dyno sheet before and after. If u got 4 rwhp, I'm going to order one. Every little bit helps. 4 HP for $50, that's worth it to me.
