Ok, I have put about 1800 miles on the car with the Greddy s/c installed and have only had one problem... I went to the dyno yesterday trying to get some decent numbers.... We did a setup pass that put down 113whp... Next pass did 110whp but we heard something under the hood... We looked and noticed the crank pulley wobbling. Turns out that I sheared the roll pin that holds the pulley center on the crank. We fixed it but it was the end of the day so we never got a decent pass...

 

yeah the reason trd doesnt have a s/c for these cars is just that fact.

try using a bit of cut up HARDENED steel nail as the roll pin.

 

Keep us updated on the progress of your pulley issue. I'd like to know what it took to fix the pulley issue. Do you have an aftermarket pulley?

Ignore hotbox.

 

the stock roll pin is very flimsy aluminum , much easier to break / bend then any hardened piece of steel would be.


how about we ignore you......

 

thats not fun.

 

I actually should have said ignore hotbox's negativity. The hardened steel is probably a good idea along with many of his suggestions. I just wish the knowledgable people were as positive/helpful on this site concerning forced induction as the are with exterior, interior, and ICE experts.

No, it doesn't sound good. I wanted to put the Greddy on my xB. I probably won't now, because I am concerned about the reliability of it with forced induction in a daily driver. Also, I'm dead set on a Mustang for my track car.

 

^I think thats a wise decision. Ive thought that myself actually. Its not that Im worried whether or not the engine can take boosting, its simply that it would be cheaper to make the mustang go way faster. Plus, them v8's are bulletproof, at least thats my personal experience.

 

the only remotely negative thing about my first post was the fact as to the pin breaking is teh reason trd didn't invest time and money on a supercharger for the 1nz. it's an easy fix though. hardened steel , welding if you're og , lol .

sorry about the pin breaking bro. upgrade time happy modding.

 

I'm not worried about the pin breaking. Thats small stuff. As for repair, we pulled the pulley ( I have the Perrin) and drilled out the sheared and mushroomed over pin. We then installed another roll pin (not hardened and put it back together. So far, no problems. If it shears again, I will put in a hardened solid dowel and give that a whirl. The problem with a hardened pin is then the pin is harder than the pulley so you may start to walk the hole in the aluminum pulley.

The post was more of a thing to watch out for with other people using the kit. We are still not quite sure why it broke. Wether it was the extra power from the charger or what. The bolt was actually loose at the time so again, I dont know if it loosened from the pin brakeing and the pulley wobbling in turn loosening the bolt. So now it has a new pin and a torqued bolt so we can see now.

The reliability of the kit is still great, this is probably just a remote incident. So we will boost the hell out of this kit and beat the snot out of it and see if it happens again.

 

Good info, I am glad you shared this!!

 

Thanks for the looking out.. How mucyh boost are you running on this thing? Is it stock, or have you turned it up?

 

I hope you checked the alternator pulley and the power steering pulley to make sure that they are still in good shape with no irregularities. only thing I could think is if the belt was installed with one rib off the end of the crank pully it would make the pulley tilt very slightly to realign with the rest of the system. but I doubt that would have been the problem. just a thought. but I wouldnt know exactly as I dont have a s/c.

 

That sounds pretty low my car ran 106whp N/A. I also had a problem with my pulley the little pin broke and the stub that was left cut a small groove in the pulley now I need a new one.

 

i have the SC never had that problem.. what made you check that anyways???

BTW what years are all you cars.. trying to see if any one has installed it in a 06 xb yet.. becuse i found out that it wont work the emanage part..

 

I just destroyed my pulley over the weekend it also is the perrin unit I don't know the root of the problem but I think the extra hp from the turbo is a place to start. I put the stock pulley back on just in case the pin breaks again the steel pulley can take a bit more abuse.

 

This pin that you are referring to; the one on mine looks like a rolled metal pin. Its bluish-black in color. I assumed it was made out of steel, but apparently no? Also, mine was pretty loose in the hole, it fell out when I pulled my crank pulley off.

 

I dont have that Perrin pulley on mines the pin is fine... glad to have you guys posting on this issue i was looking at getting that pulley to add with my SC

 

okay what is the average dyno on a greddy supercharger ? and does this Pin / pulley problem only happen on cars with an aftermarket pulley ?

 

alright i just got scared out of getting the supercharger that and the cost just knocked me out of that idea

 

Of course the number was low. As soon as we built any boost, the crank would spin without spinning the crank pulley. The number definitley wasnt accurate.
