ok guy/girls i talked to Unorthodox about getting us pulleys and a bottom pulley for the s/c

underdrive
crank pulley /ultra s
• Real HP & torque gains across entire RPM range
• One of the highest HP/Torque per dollar gains on the market
• The broadest range of applications available
• Over 8 years of use in "real world" applications from street to strip to rally to road course
• Better than OEM belt fitment & alignment
• Accessory pulleys available separately for many applications
• CAD designed & CNC'd from 6061 Aluminum billet

Our most popular crank pulleys, the ones everyone is familiar with. This version of our crank pulleys increases performance because they underdrive all the accessories (15-20% more power), unlike accessory only kits out there that do not include the crank pulley. This means one you air conditioning is on our crank pulleys give you more power back to the wheels by not letting the air conditioning compressor rob as much power.

However, we do not push the amount or percentage of under drive too far for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving. We always keep our underdrive percentage under 20% which is what allows us to maintain factory specified outputs for all your accessories. Our testing has found for most vehicle models you can upgrade your stereo to a system of up to 600 watts (RMS) and not have any charging problems.

For most applications all of the underdriving is done at the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are realized. The Ultra Series underdrive crank pulleys are available in polished aluminum finish.

and the s/c pulley
i was talking to him about and know what i wanted to do right of the bat he was tell me he has done this for other ppl with they same problem with the chance of losing the warranty so its been done with other cars and they have done this.

I have talked to him about the balance of the rotating assembly. he said a majority of the car now days are internally balance now, so it will have no effect on the rotating assembly.

Then he goes to say well to make it worth your wild and mine u will need 40-50 ppl.

And the pulleys to everything u want to make which it:
• Alternator
• Power steering pump
• Water pump
• Crank
• S/C bottom pulley


I really think this will be a great upgrade for are trucks and an even better upgrade for the s/c guys. Not having a SST (special service tool) to change out the pulley. Worrying about losing your warranty. Damaging your pulley putting it on and off.

So if anyone has an way to get to an extra pulley or can get one from a local junk yard it would be great. I will be looking for them to.

I don’t expect someone with a s/c do send a bottom pulley so when I get mine lol I hope lol soon I will be sending it off with the rest.

Again we need 40-50 first then getting the pulleys second.


Thanks guys/girls I hope u think it’s a great idea as much as I do.

And if u have any questions let me know and I will call him to ask

325-400 for a kit
s/c pulley around 200-275
that’s an est. guys without pulley for them to see


this started in xr-underground.com but a member pointed it will be good for reg Tacoma’s, Fj, and anything with 4.0l now I don’t know is the s/c pull will work for a Fj because of the difference in the fit kit but maybe some can clear that up



Chris
i am mostly on xru but because i am an x-runner but i think u guy/girls would like this to. so i will check back here from time to time and here it the adress to the one on xru http://www.xr-underground.com/forum/showthread.php?t=9322

p.s i am not making any money off this i am just trying to get stuff out for are cars so they price i get and the info i get will be straight from them
this is to see if there is 40-50 ppl

you are nuts if you think you ever get something for nothing

in normal operating ranges
you are NOT going to get a 20% gain in power

its a numbers games
& its NEVER one to one

if all was said was true
the manufacturers would do it !!!!!

in normal ranges below 2000rpm
your ecu is programmed for the best efficiency
you are NEVER going to power your whole system
at Idle with a 20% reduction on your alternator
or the AC........NEVER

where you would see the gain
is possibly from 75-80mph range
to 110 mph
where does one get a chance to do that
without getting a ticket
losing a license or going to jail

if that were the case all sports cars would be underdriven
THEY ARE NOT !!!!

maybe all race cars
but not cars that have to be driven in normal conditions
slow......
stop & go......

the same could be accomplished with a 20%
reduction in tranny or rear end gearing

yet that results in LUGGING the engine
which is very inefficient

stand still long enuf for anyone to blow smoke
up your butt
if you like

not news
not good news

I had underdrive pulleys on my Saleen Mustang, and I had to put a new alternator on it every year until I put the stock pulleys back on. I know they're not the same brand as Unorthodox, but I still think that slowing down the accessories is not good, since our trucks only idle at about 650 rpm anyway.

do u have any dyno numbers to prove that on this company
and they say they keep it under 20% and it verys from car to car and it from 15-20 gain when is it ever what a company post think about it u really need to relax dood have u had problems with pulleys and u used unorthadox al i ask is proof not ur opinion

sorry bro what company was it. i have just noticed that unorthodox is the only one that i have seen to get any gains from and they don't go over board with there reduction

every time you put on an underdrive pulley kit your getting less charge from the alternator, thats just fact. If the Unorthodox kit doesn't underdrive as much then it won't gain as much power as other kits, sorry it's just plain physics. I am actually quite familier with unorthodox products, great stuff, very little complaints but i wouldn't ever put an underdrive pulley kit on my truck, regardless of brand. Didn't even put one on my eagle talon even though my friend offered to give me his for free (he put on a sound system and the underdrive kit just wasn't going to cut it)

heres the deal searcy 1321 (???????)

what you are talking about has been termed

negative HP
residual HP
frictional loss HP

all are simply a result of what it takes to actually run the engine

even if i agreed with you
for a factual example
it takes on average 15 - 20 hp to move a vehicle down the
hiway at 60mph flat & level....no wind

thats any comparable sized auto
so at 20HP times the 20% you think you are going to get
thats 4hp

at constant speed
NO ONE can detect 4HP
so what is you gain worth

now if you were to run same vehicle down same road.....
nothing hooked up flat & level.... no wind
you still wouldnt notice it...........
only on MPG
less HP..........more MPG
less frictional loss.......more MPG

when it comes down to the dyno
most dont have AC hooked up
auto trannys
really dont need an alternator

not just for Dyno pulls !!!
yes for endurance or failure testing

so a 239HP engine is NOT going to put out 20% more HP
NOT even wide open


only in your mind !!
