I ve been reading on this site for the last few months and have read some pretty crazy things about the ATI blower,(Good and Bad) I have decided to go with the kit because of the horsepower number I ve seen on proply tuned cars. I know the kit can be made safe for everyday use and timming is a major issue...... >> My Questions is what othe parts will I need to make the car run safe for everyday(without internals) and what should I tell the people who will be tunning my car to adjust look out for ect.<< All this info is greatly appreciated and Thanks in advance for all your help,Just dont want a Blown motor

 

Also if anyone an reccomend any good install and tune shops for the ATI in Florida ,please let me know iam loc. in Miami-Gabriel

 

Check with Josahn. He lived in SFL and I think he just posted in the coupe forum that he has a S/C'd G35. Maybe he can share his experiences with you.

Also, Lokey Infiniti in Clearwater FL has done several S/C installs. I'm not sure if they've done ATI, but I know both Scott (Esemes) and Craig (Gspot35) have had their Vortec's installed there. There is also a local tuner who works wonders near by.

P.S.- Check out the link in my sig. The FGC is currently accepting new members.

 

Dude, go with the Vortech. I know of only one person with an ATI that hasn't blown his motor. Just my $.02

 

the reason I am doing the ati is because I got a great deal and I ve read , that if installed and tuned properly it runs just as safe as other ,I also know its not a complete kit and has to have some more componets added? btw when is your next sfl g35/z meet so I can attend. thanks ... keep the comments coming

 

The next SFL meet details can be found at this link Mother of all SOUTH FL meets

Most of the people in FL that are on this message board (as of now at least 62 of them that are members of the Florida G35 Club) hand out in the FGC Forum. This forum is here on G35driver, just click this link to catch up on some of the things taking place including the "All Florida Meet" on March 5th. (THIS IS A MUST READ!) Florida G35 Club Forum

There was also one guy RICH who installed his own ATI procharger and he had way too many problems with it. It spit oil everywhere, had belt slippage problems, etc... He removed the procharger and went with a Greddy TT setup and also went the forged internals route. I'm thinking he's either running 10 or 11psi with a little bit over 450-ish rwhp!

This is definitely a good club to check out if you live in FL and have questions about FI. Club sponsor Lokey Infiniti can answer most of your FI questions. too

 

I never had belt slippage problems. The belts ATI uses are far superior then Vortech. They are a Gates ribbed belt. I'm not sure how it could slip! The ATI is definately worthy of some good numbers if tuned properly.

 

Maybe that's why the ATI is blowing so many motors...you said the belt was ripped...this means it couldn't slip under conditions where it would absolutely have to, therefore putting major strain on the internals. As far as the ATI belt being superior to the stock Vortech, I agree. I upgraded to the Gates belt recently and it's a world of dif.

 

You are wrong Randy. You NEVER want your belt to slip. There should NEVER be a case where you want your belt to slip. Thats what blow off/bypass valves are for! A cog belt on a supercharger is the way to go!

 

Well, then I'm not WRONG, Vortech is. I called them for that info and wanted to buy the main serp belt to match my smaller cog belt and they told me that. If you'll remember, I was having a belt slippage problem a while back and that is what I was told when I called them for a cog belt/pulley to replace the main serp.

 

So they told you that your belt should slip occasionally?

 

Kevin,

At the CFL dyno day there was a guy with an ATI'd 350Z who posted on my350z.com under the name "Noahbuddy". He was having belt slipping problems because the instructions with the ATI kit told him (and he even broke out the instructions) to run the main belt so that the non-cogged side of the belt ran on the tensioner pulley. According to him, the tensioner only tightened in one direction and in order to tighten the tensioner the toothed belt had to have the smooth side come in contact with the tensioner pulley.

He had dynos of 350+rwhp with him of that SAME SET UP, but that day he was barely getting 250+rwhp due to his belt slipping.

He pulled out his S/C installations and read them for 30+ minutes. He borrowed tools from the shop we were at and double and triple checked his S/C belt routing. He even was asking everyone else to look over the setup.

Not sure what you're referring to about no belt slippage. Only thing I can think of is that he ran the belt wrong, but there were a good 15 people there that agreed his install was according to the book.

 

Yeah, it does look funny the way they have you run it. But, if I remember right, the pully you go under isn't cogged, so it wouldn't matter which way you run it.

In that picture you can see that my cogged belt does go over the pully, but that the pully isn't cogged. I remember when I first had it put in there was a lot of questions about if that was the right way.

Its kind of funny actually because right now everytime I start my car my belt squeels until it warms up. I never even considered the sc'er belts as being a culprit, I have just assumed it is my serpintine belt. Of course I haven't seen/driven the car in so long that its all kinda hazy.... Oh, and with all the oil from the blow by I just assumed that oil on the serpintine belt made it squeel a bit! When I get the car back I'll have to check it all out!

 

Yep, and gave me the reason I gave you.

 

Wow, that absolutely amazes me.

First off - If Vortech designed the system to 'slip' to protect itself it shows how little engineering went into this supercharing. Mechanically, you would never be able to trust that a belt will or will not slip. What if the belt is a little too tight? Thats a terrible thing.

Second off - I can't believe that they would tell a customer that. "oh yeah, that nasty squealing noise and loss of horsepower is a safeguard and is supposed to happen." You've got to be kidding me!

There are many aspects of the Vortech that I like. I think they did a good job designing it and it looks like a great kit. I honestly feel that the Vortech employee who told you that the belt is designed to slip either didn't say what they meant to say or is on drugs.

If it is supposed to slip why would you upgrade to cogs??? I'm a little confused on that one.
