vortech with a wastegate

Just to set the record straight, I removed the manual boost controller as Booger said. I did not however replace with an electronic boost controller. I simply relied on the 8 psi spring in the wastegate.
Forget what AAM is trying to sell you guys, you can do this all for about $400 + tuning. PM me if you want details. You don't need injectors, or a fuel system upgrade as you are not using any more air than a stock Vortech setup. They can also keep their reflash too. As far as the wastegate before or after the IC, I had mine before the IC and AAM reinstalled my system in someone else's car and put it after the IC. Their stance at the time was that it shouldn't matter. I think it was just the easy way out.
Good luck to importofamerica on your conquest.

[QUOTE=gspot35;6372904]Here's some pics I can't remember if I ever posted.
I think it's great that this got stirred up! Good luck in your hp gains!
This is outstanding. If you look at the overall of the project it seems like the most you will pay for is the weld, the wastegate, the pulley, and a boost controller to keep everything safe. This is all the motivation I need to produce something like this for myself. Gspot you have to hit me up on the pm and let me know how you completely did it we gots to talk!
I seen this yesterday in a mustang magazine and it put out some nice power 
I also wonder if america earlier in the forum used the idea of the HKS racing bypass valve and how did that work?

I think its great they got something working for there requirements as well but correct me if im wrong... I think that the guys from 928 Motorsport achieved the goal without the need to go the wastegate path. Wouldnt you rather spend $200 on their product than alot more on a Wastegate and additional hardware?

Looks like the production one is available. $185.00

Can this thing build boost faster but still keep the same amount of boost til redline? for ex. If I see 15psi at wot now without the thing, can I use this to build boost faster around 2Krpm and still keep the full 15psi at wot or will it drop my psi?

Its a boost limiting valve. Its most useful for those with centrifugal superchargers like ati, vortech, and hks (ie, not stillen). We builed boost linearly with rpms. We only hit peak boost at peak rpm.
What this valve allows us to do is take pulley that builds boost from 1psi to 15psi, and cap it at 10psi by venting the extra air. You still build boost over the same RPM range, it just comes in quicker with the smaller pulley.
A pulley that makes 15psi and is boost limited to 10psi, will make more power at lower rpms then a pulley that makes 10psi at redline and no boost limiting valve.

Mr pharm, Arent u already running a 34/28 2.87 on a non-revup?
unlss u went to a 2.62 puley and a redline of barely 6000 rpms, u wont gain anymore boost.
also how would limitin top end boost increase low end power? your boost is tied directly to rpm. next time you dyno, let off the gas at 8 psi instead of 10. it wont havve any effect on your boost curve.
plus if your making safe power, why would you want to decrease it?
i think the wastegate would only be useful if
1. you are making unsafe hp levels at redline (wont happen without a t-trim)
2. your boost levels are just making hot air with no real increase in power (hp/psi ratio)

right now i'm running 32/28 with the 2.87 pulley on non rev. I'm seeing a little over 15psi but was wondering if there was a way to build boost faster. I was hoping this valve would be the solution to increasing low end pw but I guess not... unless I swap in the 2.62 pulley and cap the boost but that would be too much trouble.

Search my threads if your interested in it and I have a full right up on it with boost charts.
