I'm having my pullies installed this Friday so I'll throw up a post if the UPS guy shows up in time to allow me to get up to my speed shop for the install. They'll be on by Monday at the latest.....I expect these will grant a decent amount of torque gain and possibly even 6 or 7 hp. Can't beat it for 189.00! Go Steeda!
Why is everyone having them installed? I picked mine up today from Steeda and bought me a harmonic bal puller. Is there some trickyness that I don't forsee? Even the instruction sheet that comes with the pullies comes across as very simple. I'm not hacking on anyone, it's just making me feel like everyone knows something that I don't.
I also bought the SCT Xcalibrator, but will actually flash my car in two weeks when Steeda has their CAI available. I will attempt to dyno 1. Stock with Underdrive pullies 2. SCT flash w/under pull 3. the previous with CAI.

For me, that's just half of it-doing the mods myself. Of course, I know when to say when. I have no hesitations with learning how to do something and trying to do it. 2005redgt, you mentioned on your web page, you mentioned some tricky about installing the pullies. Could you elaborate? Thanks

The SCT is my next mod. Can you give any more insight into the product. And please do post your results.
Thx
I an honestly new to Flashing and have been absorbing as much as possible from this website and a couple of Steeda guys. Also, the basic info for the product is here. http://www.sctflash.com/main.php
I want to learn more about the little things that 2005REDGT mentions at his site. http://members.cardomain.com/2005redgt
Quote from his site: "The SCT tuning software has the ability to update Auto Tranny Pressures, etc. however, we did not change much. We could have also modified the injector settings and other fuel/air items as well as some other items I did not understand to well (too technical); but, we are taking it slow."
I don't have an automatic, but still enjoy learning what I can. I will definately be posting updates and data. The Steeda guys are excited about the CAI they have coming. I asked him what HP does he expect and this is what he said. "We had better than expected results but I don't want to say much until we have concrete numbers from production models" (referring to Cold Air Induction).

Hey 169Stang, I see that you are jumping right into the mods as well. I thought you were going to hold off for a while until you got the blower? I have an eye out for a lime green stang when I am in/around Royal Palm/Lox/Well area.

Underpullies are bad, you should know this!!!

That article states 2 point that I disagre wtth,
1) The "Harmonic Balanacer"
2) "Lighter aluminum" underdrive kit.
(Some of you motor guys please correct me if I am wrong)
1) The "Harmonic Balanacer" - From what I understand, our engines are internal balanced and this is mearly a dampener. Not to take away from it use, but that needs to be clearified
2) "Lighter aluminum" underdrive kit - The Steeda Underdrive kit contains 2 items, a new Smaller (Just as heavy) dampener and a water pump pully. This is not a lighter , small pully.
I would areee with the article, if the new Steeda kit was a small, flashy, light metal kit - but it is not. It is a smaller version of the dampener with a larger pully for the waterpump. The ones in the article may be sold at Circuit City and other ricer purchase places - you get what you pay for. But this is not the quality I have seen from Steeda.
Opinions ? Corrections ?

"The lightened mass and smaller rotational size allow the engine to spin more freely resulting in more power transmitted to the wheels."
The author is misrepresenting the premise that allows underdrive pulleys to work. It has nothing to do with the rotational mass of the pulley. The smaller diameter of the crank pulley changes the drive ratio to the accessory pumps thereby slowing down the pumps for a given engine rpm. Slower rotational speed of the pumps mean lower parasitic losses.
Quote from referenced link:
"Don't confuse this with making more horsepower, the engine is still making the same power, but the power that was being used to spin the larger mass of the pulley is now free to be transmitted elsewhere..."
Depends on how you measure engine horsepower. When engines were rated in gross horsepower this would have been true. Since the 70's engines have been rated in net horsepower meaning they take into account parasitic losses. Again, reduce the parasitic losses and the NET horsepower increases.
Finally, thank you for your concern about our stangs but, some people (myself included) bought the Mustang for the purpose of modifying and racing it. And that's what I plan on doing

You might want to read this article from ATI website
http://www.atiperformanceproducts.com/prod...amper_dinan.htm
Now having said all this I believe that the Steeda sets are a quality built unit and you’re probably fine installing them. But knowing the weight difference between the stock units and the ones from Steeda would be interesting.
