I was just wondering if it's possible to underdrive the YS to around 12-15 pounds of boost on a 355? Will it still be streetable?
Would it be possible to use a serpentine belt (maybe a 12-rib) to drive this thing. I used a 12-rib belt on the ati pretty successfully, with the exception of the tensioner.
And my final question is regarding the Vortech aftercooler. Why can't you use a big blower like the YS on this, where is the restriction? Is the piping too small or are the heat exchangers too small. You would think if they designed a system for high performance, it would accept a race blower, right? I e-mailed Vortech with the same questions and got no reply.
It seems to me they should make a race kit for the Z28. Look at all the stuff for the 5.0. No money in it I guess.

Thanks,
Ed

 

You can pulley it to run the boost that you are looking for and be totally streetable .The Vortech Aftercooler will be sufficent on a YS at these levels. I build custom brackets for a YS on an lt1 with a very trick tensioner setup. This is the same setup I run on my car with 24lbs of boost and a large FMIC.No belt problems last 25 passes!all at 9.1 or quicker

 

Gee, thanks for that info. I'm not looking for that much boost, just around 12-15 pounds max, but possibly more potential in the future. I have the aftercooler with V2 right now, brand new. I've also got the ati twin intercoolers, if your familiar with those.

I'll see if Vortech wants to exchange their V2 for a YS, plus all the other stuff I didn't use in the kit. I was kinda concerned because the V2 looked a lot smaller than the ati P600B!. Please e-mail me with any more details about the custom brackets-pulleys you can make. Sounds good.

 

I have a set of Z'8s custom brackets for a YSI on my new set-up. They are beautiful pieces. Thanks again Chris

I am pretty sure Vortech with do an exchange for an upgrade but don't quote me on it you'll have to contact them to be sure.

Your question regarding the streetability of a YS, well I plan on running my YSI on the street more then the strip so I would have to say yes to it being steetable. How streetable is the question that both you and I have at the moment. I am sure I will be going through alot of tires this summer.

>I contacyed Vortech to try and exchange my (brand new in box) T -trim for the YS-trim and they told me the best I could get was "Class A" ($750.00) even though it was brand new .

good luck though !

 

We'll ya, I figured that.

Tom,
What pullies are you using? Is is serpentine or cogged?

How loud is the YS trim btw? Similar to an S trim?
Thanks for the replies guys.
Ed

 

>are saying thats acceptable ?
I would sell it on ebay to get your money back for the head unit that you don't want .

 

Bowtie, after reading up on the exchange program, I see what you're saying now. I thought you meant if you exchanged the t-trim and gave Vortech the $750, you would get a YS in exchange. To get a $750 credit for a brand new blower is ludicrous IMO. Looks like selling it on e-bay may be the best option.
Thanks for the heads up!

 

>I think it really dumb that they won't exchange a brand new in box head unit and some cash for an upgraded head unit .
I too will upgrade to a YSi -trim after I get some use out of this T -trim first .

 

My buddy bought a YS-trim and was hoping to use the ATI twin high flows. Using the stock Vortech bracket there was no way to rotate the blower and have the outlet point straight down. Your best bet would be to stick with the aftercooler.

 

I'm not familiar with the ATI setup, but why couldn't you make the blower exit parallel with the ground towards the driver's side, then to the intercoolers? This is how I'll do my t-trim with an intercooler, unless the YS trims are just that gargantuan that they can't point to the side either...

 

No need to have the YS point down. I have my YSI pointing torwards the drivers side wheel where the piping comes from the intercooler. Fits perfectly fine.

That's exactly what I figured out too by looking at the V2 bolted on the bracketry. The problem is the bracket design, specifically the lower bracket. It will be in the way if you try and rotate the volute so the outlet is facing down. Like Tom said though, it is possible to point the blower outlet towards the driver side wheel.
If this is true, it shouldn't be too hard to use the twins, it would probably be necessary to custom pipe the outlet to the intercoolers though.

 

I own the YSI on an LS1 and it makes a very undesireable street car.

 

I dont see how a blower would really effect streetablity. Will it make boost down low? no. is it a good choice for a street car?not really.. BUT, when you are just driving around.. you shouldnt even notice the blower.(aside from the whine)
