Vortech Supercharging - FAQ and Notes

[GT86_2014]

any news?

[marcoaferrer]

so far nothing new. right now its a waiting game on getting the money together and deciding whether or not Im going to need swap out the intercooler and modify the A pipe. Im not trying to be secretive I just dont want to give out any half baked info watch people start screwing up there motors cause I gave wrong info. I feel more comfortable telling people what Im going to do after I test it lol knock on wood nothing goes boom like the dude that ran the sprintex 335.

wish yoy big luck!!!
I have V2 upgraded system...
the way I am thinking is to switch to toothed belt system (cog style supercharger pulley and add the same pulley to the crank) but I will have to redesign mounting bracketry....
I am waiting for your update and will be first to follow your's way...

Oh I can tell brother. I'm just waiting for you to blaze the trail so others can follow! Good luck on your build!

So I called up vortech today to get some specs on the intercooler in the kit. Tech told me that it will flow up to 1000 cfm before it becomes a restriction. On the stock vortech kit that isnt much of a problem since the H67B max flow is rated at 750cfm. But with the changes I'm planing to make to my kit it looks like Ill have to go ahead with my plan of swaping out the intercooler and changing up the charge pipe routing for a shorter design.

I might be able to get my stock washer fluid reservoir back in the car.

@Dezoris pointed out that the Vortech owners thread had gotten so long it was impossible to navigate through and find any specific info you might need. He wasnt the only one that felt so. Heres my shot at trying to compile what ever I can find that is relevant.

Ill be adding more as I filter through all the pages. Let me know if I miss something and Ill add it to this post. (This is going to be a constant work in progress) The goal is to have the important info and FAQ on the first page so people dont have to hunt it down.

v3-H67B Compressor Map:



v3-H67B Blower Specs:

Max Speed - 52,000rpm
This number was provided by Vortech over the phone. The confusing part is that we have always been lead to believe the max impeller speed is 50,000rpm. I think i figured out what caused all the confusion. When the kit was originally released the blower it shipped with was the V3-H67BC.

According to Vortech support the new blower (V3-H67B) has a max impeller speed of 52,000rpm. This means that the 2.87 pulley overspins the blower by only 166rpm when the engine is at 7,400rpm.

Max Boost - 14psi

Max Flow - 750cfm

Max HP - 525HP
(Crank Horsepower)

Peak Efficiency - 71%

How do you know if you have the updated D-Tube? anyone have a pic?

So heres what Ive gathered so far.

The stock vortech to intercooler is rated to 1000cfm. The blower I was looking at what the V3-SI which would put the blower output at somewhere between 18-20 psi on a 2.87 pulley and right around the same efficiency range as the as the stock blower.

blower specs
http://www.vortechsuperchargers.com/page.php?id=30148

I was looking into customizing the IC routing in a similar configuration as the JDL turbo kit. This isnt that hard to accomplish especially if you rotate the volute on the blower. There are 2 setting bolts (2-4 bolts actually I cant remember exactly) that allow you to rotate the position of the discharge outlet of the blower.

EDIT: The volute angle is held in place by 6 allen bolts. After removing the bolts hold the blower and tap it with a rubber mallet to loosen its rotation.



I was about ready to pull the trigger but was advised against it. I know sucks to hear but its based on my personal circumstances. It doesnt mean that someone else cant try my plan out. Reason why Im backing out is cause with the larger blower Im basically married to e85 forever since theres no way to limit boost efficiently. Even with a wastegated setup the engine is still doing the work for 18 psi even if I limit it to 12 so it starts to become an issue of engine stress. Also although it should be possible to break the 400-450 whp mark with this setup the stress put on the engine would be the same as a 550+whp turbo setup.

Vortech is honoring their exchange program that they have in place for other platforms for our kits. So if you send in your blower they will rate its condition. They will then credit you anywhere from $500 - $1000 on a new blower. With the V3-SI costing around $2400 the max someone would have the come out of pocket is $1900 to upgrade, min cost $1400.

You can skip the custom IC piping and bolt the larger blower right up to our bracketry but once you start really pushing the blower youll start to bottle neck at the intercooler.

If I do end up not pursuing this route Im still going to look into getting a custom impeller made for the stock blower to at least bump up this blowers max output a little in the mean time. Probably somewhere between 2-4 additional psi.

EDIT: bunch of typos lol....

Let me see if i can find a pic. but one easy way to tell is by seeing if your pipe has any visible welds on it and a little dent near the blower pulley

Sorry. I missed that the new one is cast. I have the old welded one. The reason why im asking is im noticing that the pipe is rubbing on the blower bolt. Not sure if the new cast pipe addresses all clearence issues throughout the routing or if this is just alignment with my specific install...

With enough tweaking you should be able to get it to not hit. I have about 2mm of clearance but I have everything tight enough that it doesnt move even after closing the hood.

[draggin_az]

after a lot of tuning and dyno time, you must have a proper exhaust set up to support the 2.87

long story short the engine will "choke out" at 6500rmps. beyond that the dyno will look like a heart about to explode on an EKG.

below 6500rpms the engine feels amazing and is much more responsive then the stock pulley.

custom header and overpipe are in the works.

[marcoaferrer]

Awsome man. Can't wait to see what your final numbers are

Im working on a solution to bring the power output for a vortech kit over the 400whp mark and maybe even the 450whp mark but it requires some changes to the kit.

You would probably need a different compressor housing to hit those numbers or a liquid to air intercooler because of the inefficiency of the compressor at the necessary boost levels, besides the fact that you're having to run at higher boost levels than you would with a more efficient compressor.
