2bad240's journey to the world of vortech
4 Attachment(s)
hey some of you know me, anyway for those that don't my name is ray.
my car has had several setups including nitrous and most recently a procharger that was a fail which prompted me to look elsewhere for power. so luckily I managed to pick up a heavily used vortech bracket from jon @ Z1 for super cheap. (thanks jon!) and today I bought a v3 si new that should be here next week, also il be doing my intercooler piping all on the driver side so I can use my treadstone trv259 intercooler. il be using this thread to update as I go. goal will be to make 18psi and whatever it does that's what it is. back story the engine is 11:1 wiesco pistons eagle rods. stock bore, tomei 272 cams and valve springs running a kinetix velocity intake and ppe longtubes. anyway here is a pic of the old setup and a couple pics from test fitting the bracket before I pull it off for coating. Attachment 393090 Attachment 393091 Attachment 393092 And lastly the blower. Attachment 393093 |
Gonna follow this build closely! Can't wait to see what it does! Good luck on the vortech.

I'm hoping for the best for you! Now that im driving mine slowly I think may 48-24 pulleys may not be enough for me.
|
Did you ever get any numbers with your procharger setup? Definitely curious but in the future I may also be looking into a new setup since the procharger is so limited.
Conway, the larger pulley moving up in size doesnt make as much of a difference as reducing the smaller pulley size. with my setup, at redline, just changing the smaller pulley from 25 to 22 changes the blower rpm from 75k to 85.5k according to procharger calculation. |
My next step would be 48-22.

Yea would have loved to see what it did after the pulley upgrade to your current setup. did it feel significantly faster? Or did it become inefficient when spinning it that high?

Great time btw. I would be very happy with 11's. was that with the high comp build and cams?
|
if you bought a new unit, why not a bigger one? like Ti or YSI?
|
I got a good deal on the si. And I think I can make the power I want with the si.

Got the blower in today and started mocking up piping and test fitting everything. It gonna be very tight fit but I think I can fit 3" piping and retain AC.
All the new piping should be here tomorrow and at this point I'm only waiting on the cog pulley for the blower Attachment 392889 Attachment 392890 Attachment 392891 |
Awesome build bro
|
That's close as ****, but good luck.
|
Did your order the blower in black Coating? Or did you paint it? Looks Good.....

Piping came in today. Starting to work on the routing now. It's gonna be a tight fit but I think it will work. Need my chop saw and a few couplers and it should be ready to go.

Thats close, I thing my procharger piping is a little looser but not by much at all.

Here is final Fitment for piping. After cutting and modding everything fits pretty good. I just need to weld on maf flange And bov flange.
