Zasker, still anxiously awaiting voltage readings, and english translations of how you believe the change has effected the car long-term .

I volunteer to take readings from my car, if you can provide good instructions on how you did yours to me, by PM would be best I guess.

I have a good multimeter and generally good EE skills, just don't know quite what I'd be looking for here.

cmf

Zasker1... correct me if I'm wrong, but your baseline dyno is with aftermarket intake, header, and cat?

Zasker1

Yes, baseline is with Header,Ct and intake. sorry about readings, we had a dust storm last night so I did not want to open my hood and risk it smamming on my head. Will try to do this tomorrow.

Zasker1

Ok,
Today I finaly had time to get some voltage readings. Although they are a bit under 14v with everyting on the drop is fairly small thus I do not see it being an issue.

Radio,AC,Heated Seats
Headlights, doom light:

Off On:
Idle: 13.71 13.3
1k: 14.17 13.8
2k: 14. 18 14..5
3k: 14. 19 14..5


I have also had some more time behind the wheel and the gains are still impressing me. 4th gear passes are now much easyer to accomplish and the car is much smoother when you mosh it from 1-5th.

so i take it that the number on the left are before the pulley and the ones on the right are after switchin out the pulley right?

Zasker1

yes, trying to format somthing with this chat engine is a pain in the ass.

This really sounds like a killer mod then! Definitly added to my to-do list!

peter_bigblock

This mod just made it to the top of my list (jumped ahead of light-weight wheels/summer tires). $275 for 9-10 whp is a good bargain.

phil217

So that slight drop in voltage wont hurt us people with stereos in their cars??? I remember seeing your car SToke at the meet and you sure did have a lot of gadgets in there...I ask cuz I had an Accord Coupe running these pulleys and it was amazing but I had no system...I hear of some stories though where the care completely dies...

Zasker1

Remember the drop is minor and realy only a factor at Idle. I supposed if you sat long enough at Idle. (few hours) you could kill your battery, but that is not something I am willing to test. ~

phil217

well, if that is the case...time to get some UR pulleys...

Dice

Hey not to sound like an ass or anything but is 150.77TQ is a bit low # for intake headers and exhaust? makes me not want to mod my tsx. Sorry for a newb question.

Zasker1

Its about average, here is comptech's own dyno of all three:

Remember, I dont have Exhaust as it does not provide much of a gain, mostly just looks, sound, braging rights.

ProjectT4

tempting tempting...


i heard that if ur car spins out, on snow or wet road it could damange the engine?! i mean it makes sense cuz smaller diamater which means it spins faster. but i live in a snowy state is that something i have to worry about with the pullys changed?!

info info plz!! thx

Stokeless_TSX

If your car spins out your gonna have more than engine damage. But if you are refering to spinning the tires as if you had mashed the throttle on a wet road. You should be fine. All those accessories spin at over 10k rpm's as it is.

NJTSXMan

I really want to get the supercharger but i don't know if i can drop all that money on it... if not, i'm highly interested in this mod.

How difficult is it to get this thing installed.. i won't be doing it myself but would I have to be searching forever to found a shop in NJ that knows how to install this thing?

ProjectT4

do i have to worry about oil starvation to the engine?!?!?!

JTso

What do you mean? Just check the oil level once in a while.

Schizm

He's curious if the oil pump is belt driven. I don't think it is but I'll defer to one of you experts.

JTso

iTrader: (2)

Ah... I see. The oil pump is not externally driven off the crank pulley. It's internally driven off the crank shaft via a chain. So the oil pump rotational speed is not affected.

ProjectT4

sweet. thanks for the info... i actually looked it up and found the same info.. so thats good. still thanks for the info!

Zasker1

Dyno will be on UR's website Shortly.

Ooh...I missed out on this little gem. Might be worth considering when my car is getting the reflash.

chuson

Hey Zasker, how does your car drive now after a couple weeks??? Does it get any smoother or faster???

Zasker1

Churson: Car runs great definaly smoother

It's $275 from this groupbuy.

Reach

Uh, Excelerate offers the 3-piece SS set for $275 shipped still, right?

BTW, this would fit the 2006s, right? I never thought to check.

Reach

whoops, jtso beat me to it

Mugenpwp

So the AC runs fine with the pulleys? Any problems of the lights being dimmer at night?

82ben

intresting i called numerous race shops and heard that u might get ingen vibration without eaven being aware of it?!?

Mugenpwp

Did anyone else do the pulleys yet?

Seems like a really good mod from what zasker posted...but wanted more feedback before dipping my hands into one....

daddydliv

I think I'm just gonna watch what happens first before I decide to jump on this mod. I just don't like the idea of swapping out the crank pulley, and seeing as how that provides the most power I don't know if it would be worth just changing the others.

peter_bigblock

Other than the question of harmonic crank damping, which it sounds like the crank pulley does not do, what are the mechanical risks of a smaller and lighter crank (and accessory) pulleys? The accessories turn slightly slower, I understand, and that has some effect on voltage, a/c, etc. Those sound manageable, esp. with the stock stereo.

So, what is the mechanical risk from a light, small pulley set?

vasu

if i have a couple amps in my car (300w and 100w), is this a mod i want to avoid?

Stokeless_TSX

hehe 300w and 100w??? you will be fine im worried about mine the stock amp and a 1000w RMS RF power series amp..thats the one that scares me lol SO i have what 1300 or so watts for my system? and im gonna replace the stock amp with a bigger one so i think u will be fine. I am the one thats scared lol.

Mugenpwp

I did some research and found this article.

Link to Myths of crank pulleys n dampers

Been through several honda/acura boards and many people have used the SS and SSc pulleys with no problems whatsoever, some with over 2 years of use.

So they are pretty safe to use....

ianS

I want to know too, is there ne dimming problem when idling?

JTso

iTrader: (2)

UPS just dropped off a set of these... time to get busy.

Are you gonna do another dyno Johnny?

JTso

That's the plan.
