im looking to put a intercooler on my 95 z28.i just put a 9lb pully on my head uunit.where to get one that fits and where to put it in the car.i think i need one.the seems to be runinng hotter.thanks to anybodie with input please help

 

1) Do a search on powerdyne
2) Get that pulley off. It's way to big for that unit if you're seeing 9psi in the manifold, if it is the unit for lt1's. If it isnt... well... that's another story.
3) Contact Powerdyne for what they reccomend.
4) Dont drive the car till you swapped pulleys, just incase

Increasing boost increases heat. You should have known that beforehand.

You'll find VERY few powerdyne's on lt1's push anything more then 6psi. That and you cant easily intercool them because the head unit isnt strong enough to push much air. You're in bad shape if you spin it that hard - it'll overheat the air to get that extra pressure, and that can lead to the detonation which will kill your engine.

Get it back to the original pulley. Then do a search on powerdyne (I cant say that enough). My reccomendation is, if you want to use the powerdyne and get some cooling, use a water/alcy injection system. That'll be most of what you can get easily. If you are serious, sell the powerdyne and get something else.

If you have any other questions, shoot away, but realize changing pulleys without knowing what you should/should not on a head unit is asking to nuke your motor. There is power to be had if you do it right, but it's a dangerous game.

 

or, you could run a 75 shot of nitrous to cool the whole thing down.Just a thought.

 

*cough*kaboom*cough*

 

I have ran 6 bottles thru mine with out one problem and have even ran a 175 shot just for fun.

 

I put the 6 psi pulley on mine and it only reads 4 psi on my boost guage.
I just got the 9 psi pulley and with that should get a few more pounds boost.I shift my car at 5400 rpm or less and want it to spool up faster in the lower rpms.
If you get a water/methanol injection kit get one that uses the stock windshield bottle which holds a gallon with a low level light.
That would be your easiest best bet and cost about 400-450.00.

 

If you pulley down the Powerdyne, you can fab up a 4" inlet tube to safely gain psi. We saw a 2psi increase on my friends Powerdyne when we made a 4" inlet tube. Seems common among Powerdynes. Cool deal.

 

I know this is a really dumb question... but where exactly is the inlet tube? Is it the tube from the s/c to the air filter?

Yes

 

OK... thanks.

 

So you would need some drain plumbing ABS fittings with some 45 and 90 degree elbows and 4' to 3" reducers to mate it to the elbow that goes into the head unit and the MAF on the other side.
Would a fabbed setup like that be something like what you're talking about?
It would be kind of like an expansion chamber in the air intake between the MAF and the supercharger intake elbow.
That would not be too hard or expensive to make.
Will this work?

We used 4" tubing from the start of the Powerdyne inlet tube that led into the 4" inlet K&N. We also located the IAT to the inlet side.

 

Did you put your MAF on the pressure side or did you run it on the inlet side like it says in the instructions?

 

Sorry, to the maf, then the filter.

 

I'm still confused.
Please describe using the direction of air flow.
eg. filter,MAF, 4" tube,s/c elbow or filter, tube, s/c elbow, MAF.
Does the 4 " tube run from the K&N to the MAF then the powerdyne head unit
Or did you locate the MAF before the elbow into the intake and just run the 4" tube between the filter and the powerdyne?

Thanks Dave for your help.
