Why would you start with the biggest? Why not start small and go bigger. Wouldn't that be the safer approach?

Correct me if I am wrong.

 

Update: I put the middle plate in this afternoon and went for a drive....unfortunately I still got some creep at redline in second gear. Tomorrow I'll put in the last plate & hopefully it'll solve my problemos.

You are correct. That would be the safe way of doing it. I am going to start with the smallest "port" then work my way to the larger ones. I'm not really sure why Jyro said to start large then work my way to the smaller ones.

 

Just got my plates in this morning. I'm gonna post pics here in a second.

 

Right out of the package

Largest port to smallest

 

That is the "safest" way to do it, but if a smaller opening fixes the problem, you won't know if a bigger one would have done the same thing, but still allowed more flow. . . and more power.

By starting with the bigger ones you can work down to the largest opening that still fixes the problem.

 

ya I tried the middle sized plate. Didn't stop creep. So I'm letting the car cool down before I get back under it to put in the smallest.

My pics didnt load up

 

I've got the smallest plate in and my boost controller set to 10psi and still creeping to almost 12. This sucks. So what I'm going to do tomorrow is put in the medium sized one at the end of the midpipe and the largest size and the beginning. Then see if that works

I'll do some more tuning with my boost controller. But I also turned it off and ran of the wg spring so should have seen maybe 7-8psi, it went to about 11psi.

How come I have so much creep? .......creeeeeeepy....

 

I went out last night with the middle plate on and unfortunately still got some creep...hopefully it was such a small amount of creep that it'll be cleared up when I put on the smallest plate today.....will up date soon.

JyRO...you said that thee new plates were slightly modified from the first batch of plates...do you think maybe the diameters are a little too large now?

 

I'm going to put the largest one on the front flange connection and the medium on the rear. Hopefully that will be enough.

 

OK...yesterday afternoon I put the smallest plate in and drove it for a while...I got practically no boost creep! I drove it hard for a while, and on my last leg of the highway, I pushed it very hard and got very slight boost creep at around 8,200 RPM. Totally acceptable for me.

 

So what is up with my car? I have the middle sized plate up front and the smallest in the rear. And still creeping, I have to make sure I don't fully press the accelerator. I'm wondering if it has to do with the settings in my PFC. I'm going to my tuner this weekend though so we should get some stuff solved.

 

Could be your settings. . .or maybe your wastegate is not fully opening??? Just trying to throw out some guesses for ya????

 

Guys,

Believe it or not, I don't have internet access from home right now. And I was out of the office yesterday. Let me see if I can answer some questions.

rxslim was correct - If you start with the smallest, and it fixes the problem, most people wouldn't want to go to the trouble to try the next larger size ... and find out it didn't fix the problem, and have to go back to the smaller. Starting with the biggest is still going to be safer than no plate and all. And if it does the job, there's no need to try another size. It's just generally faster to start with the biggest port and work your way down.

DMoney - The reason I have sent everyone 3 plates at a time is that everybody's set-up is a bit different. If one plate fit all, I would just send one. Well, one plate with a very small hole would fit all, but would also limit flow excessively (and limit h.p.).

Your set-up may have some problems. But running 2 plates (smallest one included) shouldn't do any more than running the smallest one alone. Try to find out if there is something off with your set-up, and in the worst case scenario, I can fab up a smaller ported plate. But that's sort of a crap shoot if it will be small enough. And I think your problem may be elsewhere.


3GRX7 - If the smallest one worked for you, with just a hint of creep when you're really beating on it, that means its the perfect plate for you. You asked if I thought maybe the diameters are a little too large now. Well, no ... I don't think so. The sizes now are more focused into a more specific range. If anything, I was afraid they were too small now. But apparently that's not the case. Shoot, I may have to go to 4 plates (and include a gasket and bolts).

Doing a restriction in the airflow passage instead in the exhaust would you have the same results? I'm sorry if its sounds stupid but i always wondered what would the results be..
Anyone? Thanks!

 

I'd have to think about that, but off hand it sounds like a real good way to screw up your a/f ratio, and a lot harder to control accurately. But someone smarter than me may know better.

 

Depending on what is up with my car on Sunday I might just get he wastegate ported. IDK yet

 

Just a thought - Would one of you first 8 guys that bought some of my original plates that have the smallest port plate available be willing to send the smallest ported plate to DMoney?

This may save him the trouble of getting the wastegate ported.

There are people smarter than you!?

I'm doing a bunch of work to my car right now, including new vacuum lines and intercooler. It might change the plate that I will need when I'm all done. I wouldn't mind sending D-money the small plate that I'm not using, but there's a chance I may need it back in the future. . . at least he would know if it fixes his troubles.

PM me if interested D.

 

that would be really kick *** if someone did that. I would send them my smallest size plate in exchange.

Is their a difference in the original plates compared to these?

 

Any one got n extra one they arent going to need???

 

hey dude i'll sell you mine

 

FD3S2005 - Was anybody able to help you out? If you still need a plate, shoot me an email at joliver@hatci.com

If anyone isn't using their smallest plate, I'll buy that off of them. I'm using a 2.5" flange right now, but I'm still creeping, and I'd like to try one of these, but am kind of short on $$$.

 

I may need one of these soon, due to too much power+stock clutch. The stock W/G spring is set at what, 7/8 pounds? I have a turbo-back, I'm trying to keep the boost as low as possible until I get the clutch, any suggestions in the size of the plate?
