20+HP gain for your G50

[5seryan]

Notice how the Wussie is always the smart guys haha. nitrous is cheap power. its the smart way to go. When i was younger i use to get into fights... i usually ran as i was quite small... so i became accustomed to being called a wussies. one time i decided that i didnt feel like hearing that word. and i paid the price. i got called a wussie alot after that. cus i always ran like the smart kid instead of doing it the hard way.

[elwesso]

Heres the thign... if you car is already faster without nitrous, then it becomes even stupid faster with nitrous.

You know, I've never tried that. That makes sense to turn on and off at specific times. Basically the only time I arm it is right before I know I am going to use it. After I hit it I turn the switch off. I don't want to forget and leave the switch on .The installation instructions told me not to purge with engine off. Hope that helps.

What nos system ?? car looks great, got attacked by VIRUS from ur link.

[superuber]

It's a jwt system. Like wes said, your car becomes stupid fast.It's like your car on crack. Get the picture?Sorry about the link. I hope you were protected. I got 300 hits in one day!

yes was protected.back in HS i had a 71 442 w/nos, i know exactly what it is like.recently drove my friends 96 impala w/ a 150 shot spun tires at 80mphleft a vette in the dust.hoe often do u squeeze ? any ill effects ?

[superuber]

I use it almost every day. I have cut back because the speed shop I get my tank filled closed down. The other speed shop around here is a little further away. I was a little careful about using it when I first got it, but now I'm not. My bottle is good for 20 to 25 shots. I haven't had any ill effects. I only have 80K on my Q. I maintain it very well. Compared to other mods the JWT NOS is very affordable. I have less than $1300 in my system.

Quick update on the pulleys....

We should see the completed pulleys by the end of this month, but I can't guarantee it. I will get the 1st set and then test it out for approx 1 week, to see if there are no side effects to this mod. I seen some pulleys that destroy the front crank seal in the past and then you end up seeing oil leaking from the pulley area. I drive alot so I should be able to get 1K miles within a week of driving to get a feel for it, and test out any probable issues. I do not know what they will look like or what the final price will be, so do not ask me.

BTW NOS is for wussies

Any word on the pulleys? I am REALLY wanting to bolt these on!

[QUOTE=Q45tech]Flywheel steady state power as measured on an engine water brake dyno not rear wheel tire drum corrected compensated fudged power............is the criteria!

Are you saying that rear wheel HP is not an accurate way of measuring performance improvements? Clearly there are HUGE differences between different dynos (engine and rear wheel) but it seems that putting a Q on a rear wheel dyno with stock pulleys and then immediately afterwards with aftermarket pulleys with few to no variables changing (temp, humidity etc) would be a very effective way of measuring gains.

BTW on a Mustang 5.0 underdrive pulleys are worth 5-10 rear wheel HP. I always reference Mustang modifications because:-I own one-The mustang aftermarket is huge and parts are well tested-Many Mustang owners perform before and after dyno pulls=accurate results

Incidentantly I think that underdrive pulleys would be a better mod as long as long as there are built in cooling, electrical and power steering reserves. Big car companys do not tune their cars to the edge becausemany people don't take care of their cars. Nico owners must be different and so can probably be trusted to not let their car idle in southern Arizona with the AC on with 150,000 mile coolant and crap clogging the radiator.

[elwesso]

Just to sorta give an update to you guys, I am getting the first set, since BlackBird has since decided to get rid of his Q.. however that wont change anything.. I think that Ill be getting the pulleys in the next few weeks... From there ill install them and run them about 2 weeks or so and then we'll go from there.

[qsiguy]

........I think that underdrive pulleys would be a better mod as long as long as.......

I don't think we are talking about "underdrive" pulleys. If memory serves without re-reading all the posts here, these are supposed to be only lighter in weight with the same diameter.

[elwesso]

This is correct, they are not underdrive, they are just lightweight. Its really only the crank pulley. The water pump pulley is going to be done so that it sorta looks cool..

[bullittandy]

I understand that anything lighter is generally good for performance. But the few ounces on one pulley that are lost doesn't seem like it could be felt. Lightened flywheels are noticable but thats losing 3-8 pounds. Maybe I'm missing something?

[elwesso]

The water pump pulley is merely for looks.. the crank pulley will be lightened by about 10 lbs if i understand correctly.

10lbs!!!!!!! I had no idea they were so heavy.That makes alot more sense. If the engine is internally balanced then why does it have a 10lb pulley on the front? 10lbs makes it seem like a balancer rather than a pulley.

[elwesso]

From what I remember him saying, the stock crank pulley weighs about 15 lbs, and theyre going to reduce it to about 5..

All nissan engines are internally balanced, they probably just have the harmonic balancer to ensure whisper quiet and smooth operation, so you cant feel anything...

We'll see how they turn out, if I dont like them ill just put my stock stuff back on... not a huge deal!

[BlackBirdVQ]

BIG UPDATE- I got the crank pulley in yesterday in the mail. It weights approx 1 pound and looks awesome. I didnt take any pictures of it- but I will be shipping it to "elwesso" tomorrow so he can put it on his G50 to test it out. Hopefully he can arrange a before and after dyno for all the people to see. I do not know the exac pricing on the pulley yet.... I got mine for free for hooking up this whole deal, but since I am selling my G50, it would be pointless for me to leave that on there. And since I owe Wes some kudos for helping me out with part # searches etc durring my G50 experience, I decided to just give him my pulley as my token of appreciation.

[Q45tech]

One might wander over to the other my350z and G35driver dedicated sites and search for problems with aftermarket crankshaft pullies besides balance and wear effects. In lower the mass and forgetting the balance corrections they have created some galling poor quality units.Pictures of pulley and crankshaft damage...................many time you don't get the quality you think you are paying for in aftermarket..............a function of low production runs.

Man, this is great! I have heard great things about after market pulleys!Let me know when I can buy. My paypal account is ready and waiting!

Yeah well if you purchase some cheap knock off pulleys on Ebay.... you get what you pay for. I personally NEVER had a problem with ANY Unorthodox Racing pulley that I've had in the last 2 cars. I think I have over 75K miles on the Max with one, and the engine has almost 160K miles on it. But then again you cant compare a pos VQ35 to a smooth reliable VQ30. Only problems that I am aware of with pulleys on VQs is that some of them tear up the crank seal and cause oil leaks. We made sure this wasn't going to be the case with this pulley.

UPDATE:

I recently removed the pullies from my G35 Coupe.

Although the lightened, underdriven pullies netted me about 5 hp, they also were NOT appreciated by my engine.

It didn't idle as smoothly, and one of the other guys that ordered them had a catastrophic failure of his, resulting in a broken crank keyway and requiring a complete crank replacement (ie, rebuild).

And no, they weren't "ebay knockoffs".

When I removed mine, it was fine, but for 5 hp, I can punch out my cats, cut off the rearmost muffler, add 5 psi to each tire, clean the intake tract, advance the base timing... any number of things.

[BlackBirdVQ]

Nice, broken key way.... seen it WAAAY too many times on Acuras when people dont know how to resintall a crank pulley after doing a timin belt. It was with OEM pulleys.

[AZhitman]

Mike - This was a materials issue, not installation. They went on courtesy of a Nissan Master Tech with 17 years experience.

By the way, I could use some Q45 chrome mirrors!!!

[1QIKQ45]

So.... What happened here?Did these ever get made? I want some!!
