I'm VERY close to heading up to Buschur soon to get some work done to my car and a good tune. Tomorrow I'm installing the walbro 255 fuel pump and AMS fuel rail myself. Then, whenever I head up to Buschur I'm getting bigger injectors, cosworth mx-1 cams, a tune, a new clutch, and a turbo upgrade.

I'm just trying to finalize some things, so I figured I'd ask on evoxforums, would you guys go ahead and just grab the blouch dominator 2, or wait for Garret to release their turbo upgrade? I wanna do this within the next 2-4 weeks or so, so hopefully garret isn't too far off with releasing their product. What would you do if you were me?

As a side note, what would you guys do for a clutch? an exedy twin, or act street disk with the HD pressure plate? My car is a DD and I will drag it a few times, but not too often. I want something with similar to stock pedal pressure, and easy to slip, because i drive in traffic quite a bit. I think my biggest worry with the exedy twin is the "chatter" I've been reading about. Anyone know how loud it is or how noticeable it is? If it's not too loud I guess it's not that big a deal, but if it is I will probably go with the Act.

So what do you guys think?

I'm currently running what you may end up having.
Blouch Dominator 2.0
Cosworth MX1
DW 800cc injectors
Exedy Twin Plate (Metal) Clutch

I like the Dominator 2.0 so far but it is pretty laggy. I know a lot of people say it's not that bad but, it's pretty bad. It spools about 800 RPM later than stock which gives you a nice dead spot in the lower RPM range. Going WOT from a roll in 1st gear is a drag... Of course if you launch it, it doesn't matter. Once the turbo spools in 1st & 2nd gear your front tires will break a little traction and cause some wheel hop.

The cams are nice, it does have a loppy idle but not so bad that it makes your car stall. At first I had to set my idle at around 1000 RPM but I have it tuned now where I can keep the stock idle :) The cams created more power in all RPM ranges, this was a big plus.

Injectors, nothing special about them..... easy to install.

Exedy twin plate clutch, this thing is great! It's almost as easy as a stock clutch. It's designed to where it doesn't have too much pressure so you can save your master cylinder from going out. I heard the ACT has high pressure which causes the weak plastic stock master cylinder to crack. Twin plates usually doesn't require as much pressure to hold the clutch since there are two discs. Since the ACT is a single, they have to make a high pressure, pressure plate to prevent it from slipping.
The only down side of the Exedy is the chatter noise that you'll get from all twin plate clutches. When you depress the clutch (release the discs) the discs rub against the pressure plate causing some chatter noise.

Sorry, I forgot to metion it but the clutch noise is only audible when your windows are rolled down. Also, the noise tends to go away most of the time when you have warmed the clutch up. The Exedy is also designed to where it engauges *one disc at a time so it's easy to slip the clutch just like the stocker.

*Releasing the clutch pedal around 10% will make the first disc grab and anything more than that will make the 2nd disc grab.

Wow, thanks for the reply's man! They were very informative and will definitely help me with my decision. That's good to heart that the chatter is only audible when the windows are down. I wish I could find a video of the chatter somewhere on youtube haha. But as for the lagginess of the blouch...this is the first time I've heard this. It kind of makes me think twice, and maybe check out FP Red, or wait for the Garret one. What would you guys say out of the three?

After some time with Exedy Twin (ceramic), I don't have any chatter anymore, but I do have noise at the time of clutch engagement. Like when you slowly start the car, you can hear rubbing while the clutch pedal is being released.

The FP Red is slightly larger so it's more than likely to cause more lag. Since the Garret is a full ball bearing type, it may have *slightly* less lag but output should be similar to the Dom 2.0.

BTW, here's my dyno sheet, it's in metric but it converts to 445whp/418wt:
http://g-force.way-nifty.com/photos/uncategorized/2009/03/08/090308_182831_2.jpg

The yellow line was the final run of that day, the narrow red line is with the stock cams & turbo. As you can see, even on the dyno it shows about 800 RPM more lag than stock.

Thanks for the replies, I am happy to hear the chatter goes away and is not that noticeable. I think that was my biggest concern. Now I just need to find a video, haha. But SiC, you're putting out some really good power man. 450WHP, that's awesome man what kind of 1/4 mile times do you think you'll be getting with that kind of power?

No idea what it would do on the 1/4 mile, 11's I hope....

I might make a video soon so you can hear the loppy idle. I doubt the clutch would be audible in the video.

I would hope you would brake into the tens with that setup. Just with the mods I have you can hit 11's with a daily driver.
As far as what turbo, I would go with the Garrett. I've been looking at its maps and configuration and you should have about the same lag as the stock turbo.

fp red spools nearly stock on ryan gates car. like 100rpm shy of stock spool

Meat, what would you say out of the three man? FP Red, Garret, or Blouch Dom 2?

Oh and SiC, if you made a video man, that would be AWESOME. :D

FP Red hands down.
But that is an opinion without seeing Dyno proof of the Garrett

wehn i went to xtremeboost in florida, i rode in a 600whp evo 8. it had a fp red under the hood.

all FPRed turbos are superior to garrett, if you look on fp's website, they sell both, and give specs for everything, you can read for yourself why FP is better then garret.

now is BLOUCH would come out with a DOM 3.... that would rock everyones world... or a DOM 4.. those are avaliable for the subaru....

I think Blouch was working on a DOM 1.. what the fuck for?

I'm currently running what you may end up having.
Blouch Dominator 2.0

It's actually refreshing to hear someone say this. Everyone keeps trying to reassure me that it's not laggy, but obviously it is.

Going WOT from a roll in 1st gear is a drag... Of course if you launch it, it doesn't matter. Once the turbo spools in 1st & 2nd gear your front tires will break a little traction and cause some wheel hop.

Fun. I can do that with my stock turbo though. :)

The cams are nice, it does have a loppy idle but not so bad that it makes your car stall. At first I had to set my idle at around 1000 RPM but I have it tuned now where I can keep the stock idle :) The cams created more power in all RPM ranges, this was a big plus.

This is why I think cams are a must-have mod. Very nice.

The only down side of the Exedy is the chatter noise that you'll get from all twin plate clutches. When you depress the clutch (release the discs) the discs rub against the pressure plate causing some chatter noise.

Is it loud? Could you take a video of it?

Good thread guys. If anyone could take a video of the twin-plate chatter, that would be absolutely fantastic. That's really the only thing keeping me from getting the exedy twin, because my evo is a DD. I think you all have changed my mind....I think I might go for the FP Red now haha, or maybe wait one or two weeks and hope Garret's turbo is out by then.

For all those that say the FP Red spools faster than the Dom 2, where did you see this? From all the dyno sheets I've seen, I'm hitting peak torque faster or just as fast as the FP Red on meth or race gas. Are you all speaking from first hand experience? Can you show us a dyno sheet that compares the stock & FP Red on the same graph like mine?

The Dom 2.0 is a 52lbs turbo and the Red is supposed to be a 57lbs. The turbine wheel is larger on the Red and *generally* this causes the spool to be slower (of course depending on the design, etc. this can vary). The Blouch uses the wheel from a Garret GT30 so it should be quite similar to the GT3076, the difference would be the ball bearing and housing.

I've attached a dyno sheet of a FP Red with the same cams & injectors as mine tuned by Works, notice the low HP & torque in the lower RPM. This car also has meth but seems to be much laggier than mine.

Also attached is my boost graph, I wish I would've printed this out comparing to stock but I wasn't thinking about stock when I was doing the printing. But as you can see, I'm hitting peak boost at around 3300 RPM but it *feels* laggier than stock. You can see the lag by looking at my other power/torque sheet.

Hey SiC that's not TOO bad man peak boost at 3300 is pretty close to stock I think....I keep going back and forth between the FP Red & The Dom 2. They seem very similar, but I still think I'm leaning toward the FP Red. Oh and I've also decided to get the AEM Water/Meth kit too, might as well throw that on when I'm getting my turbo & cams installed @ Buschur.

Oh yeah and if anyone could post a video of their exedy twin "chattering" or just driving around with it, that would be freakin awesome!

Are there any clutches that save the master cylinder and don't chatter? If not, is there an upgraded master cylinder?

My ACT street with HD plate came with a new Master Cylinder

Pics of upgraded master cylinder?

Didnt take any pics, it was a while back and the dealership mechanic told me there was a new one, when I asked about M. cylinder... But I will double check with ACT

So it looks like the FP RED and the Dom 2 are VERY similar in the power they make and the spool. So either or would probably end up with similar results. As for the clutch, I've still been searching for a vid or a sound clip of a twin-disk chatter. Still haven't found one yet. If someone knows of a vid, or wants to be super nice and make a vid, that'd be great :)

FP Red has larger compressor wheel. I wouldn't and won't deal with Blouch ever again based on my previous experience. I would go FP Red or the GT30R. The 30R has the nice choice of AR on the exhaust housings which I like but technically the FP Red has the larger compressor wheel. Can't really go wrong with either one but I suspect the FP Red is cheaper. Another option is go GT30R and send it off to FP for their HTA upgrade!

Please explain more on that HTA upgrade :)

Check out FP's site on their HTA series turbos.
