FloPro's RUNNING single turbo gts!!!

I just listened to the one with u in the garage...is the microphone making it sound muffled? And what cam is that?

How come I cannot view the videos? It is pissing me off.
I want to see and hear this machine.

Cool, cause i was kinda disappointed when i heard it...i KNOW bassani's have gotta sound better than that. Just had to make sure its the camera


Keep us updated!

quicktime fixed the problem. Thanks.

The turbo sounds nice. I can't wait to get mine.

Sounds good and looks good. My Buddy is renting out a the track over by K Zoo In a couple weeks should have my car done around then if your interested let me know and I can get ahold of him

congrats! how much boost did you run on the dyno run.

that looks fun.

Well if its a 5psi spring, doesnt that mean something else is not up to par if its not keeping it at 5psi? I mean another 10psi is a TON of boost creep. Is your waste gate big enough? I remember i saw a guy on TM who had a problem like this...although i dont htink it was that drastic, he ended up adding another wastegate to his and it was fine. I think the location of the wastegate on the system determines if it will be able to bleed off enough.

I guess my main question is what is causing a 5psi spring to boost to 15psi?

damn that thing sounds amazing.

my 7-9 psi spring is netting me ~5-6 psi. i placed the wastegate in a way that it scavenges and operateds more efficiently. im running a deltagate too, its only 35mm. i dont know how low the springs go but something doesnt sound right. maybe your gate is sticky or the diaphram has a leak.

actually i just looked at your old buildup thread and your gate is kinda where mine is. where did you run your gates refernce line to? something is not right. you were running 6psi in the beginning with the same spring?
what goes on?

I definately think something is up. Either in design or setup. I dont think u should "band aide" it unless u dont feel like fixing it.If everything is working right, it shouldnt over boost...especially not by 10psi.

Everything may be ok with what u want out of the car, all we are saying is that if its boosting thatmuch over what the spring is rated at, something is out of wack. Now do u want to fix or change it? Thats a totally different story/arguement.

Now im a rookie when it comes to this stuff so im not trying to tell you that u're wrong or how to do something, just letting my ideas run to maybe strike up some thoughts/conversation so we can all learn whats supposed to happen.

But with your WG....it was my understanding that u only had either the turbo compressor outlet or the manifold into the bottom port on the WG. When the compressor or manifold sees 10psi or whatever, the WG will open. Keeping your boost at 10psi. Now they say going from the manifold gives less spool time since the manifold sees less boost than the outlet of your turbo. So, since your boost is going way over what the spring is for...then something else is up.

You dont have a boost controller hooked up. From what i have read, you only tap into the top port for when u run a boost controller...otherwise u run it open to atmosphere. Now with a boost controller, i believe that you run a line from the intake, to the controller, then to the top port...with your bottom port in the same location as before. Then u turn the controller up or down adding more boost to your liking.

Im thinking that with the way u have it setup, u are actually creating a boost controller that cant be adjusted. The thing is that a boost controller adds pressure to the top of the spring in the WG so that its harder to open...thus giving you more boost. Now the way u have it, u have the boost from the turbo trying to push the spring open but then u also have the boost from the intake pushing back down. Thats why i think you are getting such high numbers. I wonder what will happen if u just take off that line going to the top port and just plug it

And like i said man, im not saying u or anyone else is wrong. These are just my thoughts and me trying to put 2 + 2 together from what i have learned. I would like to come to a conclusion on why its doing it, so that we can all learn about it. Now if u dont want to fix it, thats fine.

That is not correct either. I was never running 6 at WOT, I had made 6 in the past before the tune at half throttle.

I have the bottom port to the turbo and the top port t-ed with bov line into the vac line going into my FPR T. I don't see a problem with that. do you??

Like I said though, I really don't care. Everything is just fine.

thats your problem right there. the top port is the top of the diaphragm. that goes to a boost contoller ONLY that port going to your other stuff just compresses the air in the line and stops the diaphragm from opening. your bov and fpr is now just a boost controller.

edit: see above post, i replied before i read it.
