I rencently got a power enterprise tt 350z with forged internals and now my brother is looking for one. He found a ATI procharged one with 387whp but he wants more. My question is: How much potential does that system have. With and with out forged internals.
Would anyone recemmend this system.
Any advice would be great.
Thanks

 

any advice or reccomendations?

 

the ATI has great potential. I would say that after 10lbs. of boost you may want to consider seriously upgrading your internals. Remember that what blows motor is improper tunning, so you will have address the timming issue as well as A/F rate. I am in the process of possibly going to 9lbs. myself. Good luck.

 

i have the 7psi pulley and methanol injection to prevent detonation. ..stock exhaust/cats ...377rwhp 320tq ...plenty of potential with full exhaust...10 psi. ..i know guys runnin tt kits with 12.5 psi 500 rwhp stock internals....no worries...yet...upgrade injectors also and get it TUNED ..had mine done in chicago by grd. ...

 

I have another question. Why are turbo chargers producing more hp than superchargers? I mean i would think that there potential would be the same but yet i dont see any supercharged Z's with much over 400whp and i have seen a bunch of Z's with much over 500whp and some over 600. Can anyone explain this to me. Thanks

 

anyone?

 

The supercharger kits are very limited with the parts in their kits. Their piping isn't very big, their intercoolers are small, and their pullies are expensive.

When I damaged my motor with my Procharger (improper tune) I was going to rebuild, raise the boost, and have a 500whp supercharged G35. But, then I started looking in the price of upgrading the piping, the injectors, the intercooler, and having custom pullies manufactured to run the Procharger C2 compressor at 20psi with a custom wastegate setup (for boost control) and the pricing was rediculous when compared to buying a TT kit that is designed to handle 800 crank hp.

 

thanks for the info, by any chance do u remember how much it was going to cost for u to build up your motor and upgrade all the supercharger components? ballpark maybe? Thanks

 

I would guess over $3,000.

A custom made FMIC big enough to flow that much air would be well over $1000. The custom piping, which would have to be completely custom made to include the wastegate to bleed off unwanted presssure (so I wasn't running at 20psi all the time) would really make the bigger piping tricky. I would imagine that to cost around $1000 as well (painted and installed). The custom pullies would be a couple hundred dollars I would imagine, if you could find a machine shop to machine them. Procharger doesn't sell pullies that small...

So, you may be able to get it for under $3000. But, when you look at selling a new polished kit (like mine was) for $4,000 you are basically at the price of a TT ($7,000), with a lot less headaches.

 

thats true thanks alot for the help!

 

Just wondering what is the most hp anyone has seen or knows about from a supercharged 350z. Thanks

 

One of the biggest reasons the SC cant produce the power of the TT is that it takes alot hp away turning the blower . Even with larger intercooler pipes and a Big intercooler . The same psi will not produce the WHP of the TT . I would guess a 100hp is being robbed by turning the blower at high rpms and around 10 -11psi

 

Just wait, big #'s from the Procharger are on the way!

 

Get her tuned yet ? I did some more testing today...Im stuck at 13 to 13.4psi from 6000rpm to 6800rpm . Bigger IC and pipe got me to 13psi a littler sooner and cooler intake temps , But no more boost when the belt starts to slip . May try the smaller pulley to get it even sooner and call it a day , till Vortech comes up with a all cog belt set up

 

I'm having Sharif tune it on the 5&6 of this month so stay tuned

 

That's how mine was, untill I took off the intercooler.

Here is an interesting quote from the 350Z Procharger brochure:

More Low-End Boost and Horsepower
"The intercooer also acts as a pssive wastegate, flattening the boost curve at higher rpm's and allowing more boost to be dialed in at lower rpms"


Basically what they (ATI) are trying to say is at stock psi levels 7-9 the intercooler works great as far as flow is concerned. But at higher levels of boost is just plain stops out the boost curve. That the problem I used to have. We did an initial dyno run a few days with the water/meth injection system. The A/F were way rich and I think the water was putting out the spark but what was very interesting is that the boost kept increasing instead of just jumping up and staying flat. Procharger rates the C2 blower at 24psi and 1100 CFM's of airflow. From what I gather it takes about 150 cubic feet of air to make 100 horsepower. I expect the blower to make around 17-19psi at redline now and maybe 1000 CFM's of airflow. That (with proper tuning & water/meth injection) should allow us to maybe run 15-17 degrees of timing from top dead center. Water/meth injection at this point is a must because you can feel the big time temp difference on the upper plenum from not having the intercooler. Plus since I currently have the Emange Ultimate it relies heavily on the MAF sensor and right now my car thinks it's probably 200 degrees outside...lol....because the water/meth injection nozle is after the MAF sensor. I"m sure Sharif and the UTEC will be able to subtract much of the feedback from the MAF sensor. At this point I have no doubt that we will be able to get atleast 500+rwhp without any NOS. It's all theory at this point but I"m willing to bet all will work out. All I have to worry about now is the coolingmist system crapping out but there are warning lights for that plus the UTEC will pull timing if detonation is present so I should be ok.

 

Good luck!

 

I know that the Axis race 350z has 500whp on the ATI. If you were looking to make really good power with a Procharger you could make a new and improved kit if you knew the right people and had a fair amount of money at your disposal.

The problem with high boost and superchargers is based on where they are located they need some sort of spline belt somewhere which is generally what slips when you run either bigger blowers or smaller pullies. Theoretically, it wouldnt be hard to fit a bigger blower in out car under say the passenger side frame. You would need to have a custom mounting bracket made and a custom pullie with a cog on the end instead of splines and also a custom tubular front end so you could ditch the composite radiator piece. This would allow for the use of one belt that is only for gears meaning no slipping. You blower would basically be mounted in the passenger side part of the bumper near the passenger side lower part of your radiator. This would be nice because the blower would be about 2 or 3 inches away from the inlet of the intercooler (have to be custom vertical or horizontal flow if you wanted) and the piping would be very straight especially in comparison to how it is on the kit now.

Of cousre this would take money but it is just some interesting ideas I was playing around with at one point.

 

Are you sure about that? Where did you get this information?
