Sup Fellas... :vampire:

So far in terms of performance mods as you can see in my sig, I've gotten the Place-Racing CAI, Cali-Spec Cattman Y-Pipe and most recently I got the Unorthodox Racing Underdrive Pulley...
First thing I got was the CAI...I've never been Dyno'd before so I dont know how much HP I truly got but the main thing I noticed was the sound...the awesome low pitch growl it gave my car...the actual power increase seemed to be minimal, but noticeable.
With the Y-Pipe, it was the same thing. It made that growl a bit lower but, by now means was it too loud. As a matter of fact it sounds perfect to me! The power increase again was noticeable but it didn't blow my hair back...
It was with the underdrive pulley that I had the most noticeable difference in performance. Its made my acceleration must faster. Again I've never timed myself or been Dyno'd but anyone would be able to tell the difference with this mod...it was well worth it and it wasn't even as expensive as the other two I have...ASK SOMEBODY!!!
ONE...

Hey what's up,
I've thinking about getting some myself but wasn't sure how my A.C and stuff like that would work have you noticed any thing bad.Also where did you get yours from and who installed them ?
Thanks "O"

 

I turned on almost everything possible in the car and didn't notice any dimming.

 

You have had your UP on for sometime now. How much HP do you think it gives you? Doe the idle go down or or up with the Underdrive pulleys? How much do they cost and how easy are they to install?

 

I'd say it gives about 2 whp, but I don't have dyno numbers to prove/disprove the estimate.

The idle is fine.

I bought mine from Stillen for $179 (including tax and shipping), but not including the 2 belts which cost $28.

Install was pretty simple after we figured out an easier way. I'd say it'll probably take about an hour for the install.

 

This post is very surprising given that most people get 2-3hp from the UDP and 10-15 from the y-pipe. I'm sceptical and I don't think one can "feel" 2-3hp difference on a Maxima.

 

What tools did it take?

 

Well.. the UDP is said to free up low end HP and torque which is the most noticeable area of acceleration (for me at least) so I don't find this tooo far fetched.

 

You're typical wrenches... 10, 12, 14, 17, 19... flathead, philips.

IIRC, 19 socket(?) with a breaker bar.

 

My breaker bar is my dumb hoe beater
LoL

 

Hrmm is there a write-up on this anywhere (especially the new method you discovered)? and pardon my ignorance IIRC?

 

Hehehe...

IIRC = if I recall correctly

Instructions? Hmmmmm... here's a quickie:

1) Loosen all belt tension and take off the belts.
2) To take the stock crank pulley off, put the 19(?) socket with breaker bar over the pulley bolt.
3) Place the breaker bar against the control arm of the car.
4) Have someone crank the car for a split second (don't start the car) to break the bolt free.
5) Do all the mumbo jumbo stuff and swap the stock pulley with the UDP.
6) To tighten the bolt, take a hammer and whack the breaker bar on the right side (clockwise). This procedure acts like an "impact" gun.
7) Give the breaker bar about 5-10 good whacks and you should be fine. * Who needs to torque it down to the correct spec anyways? *
8) Tighten belt tensions
9) Laugh at people who actually took their starter off and used a pry bar to stop the flywheel. Get laughed at by the starter people because the crank pulley is not torqued to the correct spec.
10) Done.

If you take your car to a shop, they won't torque the pulley bolt down to the correct spec anyways.

 

You're coming out to help me with this when?? Can you add this to the how-to sticky? Thanks!

 

Can anybody help me with the following:

What does an under drive pulley do?
Does it void the factory warranty?
Can it be added to my auto max?

 

Use the search, this has all been covered before.

cool

 

Uhmmm..... it's the ghetto way so I'd be embarrassed to put this in the sticky thread.

BTW, check the sticky thread for more info or https://maxima.org/maxfaqs/sub_perfo...Performance_2a

 

Hey punkdork I would help you install if you get it so that I could install my own.

 

What was I typing?!?!?

We need to remove the starter. One of the starter bolts is torque down very hard. Turbo95Max and I had to ghetto-rig a super breaker bar to break the bolt loose.

 

I just may take you up on that. My next project is Tokicos once I get em from Kev. So it'd probably be a month or two.

 

OK, I've been hounding Ground Control.

Supposedly, they received a shipment of 4th gen top hats Wednesday... supposedly, they received my spring today... and supposedly, I'll be getting the coilovers tomorrow (we're both in NorCal so it's basically overnight). We'll see...

 

No rush Kev... I'm still waiting on Psing.. his bank's been giving him gruff. Thats why I keep all my money in an old sock under my mattress!

 

What's your address again?

If I get them tomorrow, hopefully they'll be installed on Sunday.

 

Trust me.. you don't want to go there. The sock is VERY old n funky!

 

Regarding step #3 above, I actually put my bar above the control arm. There is a subframe type structure right above the control arm. I put my wrench in that area and put a rag under the wrench so it was touching the subframe. Then I ran around and blipped the starter. On the third blip it broke free. These were very short blips because I didn't disconnect the coil to keep it from starting. It was a "tick" on the first try... a "tick" on the second... and a "wrrrr-wrrrr" on the third and I knew it was free.

I wouldn't recommend trying any other way of removing this bolt unless you have an air compressor and an impact wrench. All else is a waste of time... believe me, I spent a lot of time working on it before doing like Kev suggested and using my starter. Once I tried that it was off in a matter of minutes.

I have one more thing to add to step #5. I'd recommend putting some anti-sieze on the crank shaft or inside edge of the new pulley. This will keep them from "corroding". (You know how unlike metals don't like each other!)

 

Thanks for the info. Knowing I won't have to pay for the install makes this mod oh so much more appetizing.

 

Hey Guys... :vampire:

That is probably what I meant to say! I'm glad someone agrees w/me...I felt a big difference if the power/torque when accelerating especially in first and second gear. Forget how much HP it gives you, with this mod I could actually feel the difference.
Haven't noticed any dimming either with any of my performance mods...but now with my system, that a different story!

yup yup my bank cheated me!! da bastadsss hehe
well i think everything will be ok with that real soon... i just had a bad week $$$ wise... too many problems in too short of a span...

 

You know...if people didn't ask questions like that, you wouldn't "Need non-Maxima Friends" like you do!!!

 

Well yeah.. but.. umm.. I fixed the titles on the lumber stuff so THERE!!
