if you want, i talked to my friend with the 5th gen, and like i said, his alternator is not as strong as ours (by 10 amps), and he has a huge system, and he hasnt seen any problems wiht his A/C, and his system has been running fine.

 

and he has what pulleys? You see, I wont max out my system's power unless I goto a carshow. I might consider swapping pulleys right before a carshow..... I know it seems tedious... but its worth a try ya no??? Besides we can always rev the sh i t out of our cars when we are at carshows.

 

Does anyone have a stock pulley from their VQ lying around? I could paypal $$ to you if you could send it to an address for me. This would set up a prototype pulley to be sent to me for before/after dyno testing on a lightened crankshaft pulley.

Total price of the lightened pulleys may run around $125 from my source...I just want to get the prototyping done before I set up a group deal.

Let me know if you're interested in selling a stock VQ30 pulley.

He has the DMS UDP, its like 5 pounds less than stock, or something like that. I talked to him, he said I should have no problems. So I'm happy

 

Expect about 2fwhp with the lightened pulley. I've seen a few dynos in the past couple of weeks with the addition of the UDP and gains were in the 1-3fwhp range.

I'd definitely be interested if they end up around that price, I just don't have the money to be buying an UR one and even though my system isn't that big I don't like the idea of underdriving. I'm looking forward to hearing how this turns out.

 

So you think I will be ok with the DMS UDP? How much do they cost and where can I get them @?

 

Yes, can someone provide me w/ some info on this DMS UDP, I've never heard of that company/brand before.

 

they have a GD for them right nwo for $80 shipped in blue or black, they are so cheap because they have a small scratch on them, doesnt effect performance at all, besides its not as if you can see em =P

 

heh I dont have $80. Im counting up loose change and work checks for money! I just bought a y pipe, shift boots, and a battery tie down. I have to come up with another 379 for next month bc im buying rotors, ss brake lines, and pads... :X Min. wage sux!

 

wow nice list of mods

 

haha thanks. Im officially poor. I spend 98% of my money on mods... Im addicted. Its kinda cool when your a HS kid and mommy and daddy pay for insuarance and gas once a month. No bills exept a cell phone every now and then. Im just trying to throw as many mods on my car as I can before i get into college and become poor and screwed.

 

college is the best mod killer of all time...

 

Unfortunately I don't have the $$ to get this thing started. The GD price for about 10 people would be $100/each for an untested product. As DaveB explained, the gains would be about 2fwhp...

If any of you think we could get 10+ people for a GD then let me know and I will go ahead but the money would need to be up front since I am not rich.lol

(if anyone thinks my reputation is questionable then I will add that I am very well known on here as well as in DNE...I am VP of Public Relations in DNE and many of our members would vouch for me)

 

HA! Annnnnnnnnd you arrrrre!?! (j/k)

Is it DMS you are dealin with?

 

Can someone help me out with this though. IT's about installing the pulley, I have an auto and it requires you to lock the flywheel... I read greg's install writeup in the faq's but it doesnt say how to lock the flywheel. Do you just stick something in there to prevent it from spinning or what? I dont want to wreck the flywheel doing this.

 

Jeff, have you found a way to get a stock pulley out to them to use to design a pulley?

 

I have some people that have an extra stock pulley that would sell to me. The stock pulley isn't a problem...

It isn't DMS...it is a company called Perrin Performance. Jeff Perrin is the owner.

 

damn jeffs... haha

where are they located and how fast do you think they could design one and send it to us for test fitment... we can screw up my car this time if you'd like instead of yours... haha

 

^ Well like I said I won't be dealing this through since we would need 10 people for the GD with money up front. In other words, Perrin wants $1000 for the project...this would include 10 lightened pulleys with that price. (comes out to $100 per pulley)

They are located in Oregon...we are talking about a 2 week time for them to have all pulleys shipped out, iirc.

 

im in jeff let me know

 

I'll start a GD on these then. I think I can get 3-4 people in DNE alone on these pulleys...maybe other .org'ers would like to join in.

Group Deal thread...if interested then definitely let me know on that thread.

 

I read the link, what is considered a killer system??

 

^^A killer system...I don't know what they would consider. It's a pretty generic term. In my opinion anything above stock is going to stress the alternator/battery. I would think that alternators come from the factory with enough amperage to handle what is on the car 'stock' and maybe a little more just in case.

That is only my opinion though...please don't take that as fact.

 

I still managed to mod after starting college.

Just wait 'till you buy a house.

 

but truly the question is if the pulley is lightened and not underdriven what benefits do we get? I know 1 to 2 hp but would we go throught the revs quicker?

 

I don't think the revs would fall off as noticeably as a lightened flywheel would.
