I got one when I noticed how much my car was spiking the boost constantly with the MBC the auto trans is a PITA for spiking I have found. After the install off the Forced perf accuator Gone is my boost creep spiking and my MBC no longer needed it took 1 test drive to set the arm length on the controller and I was on my way! I can't say enough about this for a stock turbo I love it Im so glad someone suggested it to me! I got it right away and installed in like 30 mins. My boost is really consistant and hold 17 PSI and holds it longer. Just like the site shows I find it to be very straight forward.

Im very happy with mine. Now if my DP would show up from punishment I would be happy going bigger!

*sigh*

Number 2: I'm glad someone else got one of these, I've been really contemplating it lately, when does the boost start to fall off now and hwo low does it get. I'm getting sick of having 11 psi after 5500 rpm's, and the thought of bolting on another turbo without any fuel support or afc is out of the question.

Does anyone else have a review of this? I'd like to hear replies, even you T-28 guys.

Thanks
 
Mine is T28 after 5500 RPM is sitll holds 14 PSI till redline 7 grand.

And I didn't realize that I had to have perfect english to post a message sorry if Im not educated on the keyboard like some more fortunate individuals that have had it better in life and got more education then me.
 
You misunderstand me, I'm not saying that your posts have to be perfect. I'm just saying that reading them shouldn't make me want to gouge an eye out with a spoon. Just make it clear enough so that we don't have to geuss at what you're saying.

Plus, don't give me this hard life crap, I don't know how the schools ae in Canada, but we have plenty well spoken Canucks on this board. If it's really that bad, just move to America, they're practically giving education away for free.
 
I've seen alot worse.

Glad to hear the actuator works well for you. I may get one in the meantime before I purchase a full Garrett setup. The T25 is really not worth blowing past 15psi, but if you have the right intercooling, higher boost can be used. Definitely do not exceed 17psi, as the T25 is already maxed out at 250cfm at only 15psi. Remember, power is in tuning, not boost! I good investment would be a 14b turbo, as they flow almost twice as much at the same boost ( 405cfm's @ 15psi ).

Don't get down about the grammar also. You had an honest post and I understood your point. If someone doesn't like it, then they can start a school. ;)

Petetre illes veux parles en Francais et pas l'englais?

( Yes, my French is horrible :D )

Right now I have a t25 and mbc. With the mbc all the way out and t25 I run 15 psi then it drops like usual. I was thinking about upgrading to a t28 and the 17 psi actuator rod.

One of the purposes I going to get the actuator rod with the t28 is to run the boost line from the manifold directly to the wastegate. I’m hopeing this will hold about 15-17 psi since I’m on pump gas and give me a smoother spool since I’m fwd. What do you guys think?

Giving it away? You either have to be filthy rich or dirt poor to get a good "edjumacatin"

With mine I can tune it to get no boost creep like I was with MBC thats a huge bonus. I like how it hold the boost now to much higher RPM before falling off and it still maintains higher boost levels in upper RPM meaning it doesn't drop off near as much. I also like how I can run the hose straight from the compressor to the wastegate nothing in between no brass restrictor and a super short hose so there is no spiking. If I jam it out of the hole it hits 17 psi and holds it till about 5000 RPM falls to 15 and holds that till redline. It works really nicely. But its good for others wanting to run more boost to when I took it out on the street the first time to adjust the rod I was hitting and holding 19 PSI so you can tune it pretty good to match your turbo I suppose. I find the boost much more stable after driving it now for a few days. I like not needing the MBC anymore and the spiking is gone for me it was worth the money because I want to try and get into the 13's with the stock turbo, so my next question is can it be done? And what do I need to do it?

Looking at your mods I would say that getting into the 13s really depends on your clutch at this point. Replace it with either an ACT2100 or an AMS Feramic clutch. The ACT2600 is just a poor solution to needing more clamping force. Adding that extreme amount of pressure on the crank is not terribly bright ( And ACT does admit that it places extra stress on the thrust bearing ).

www.slowboyracing.com For the ACT
www.automotorsports.com For the Feramic clutch

With a good clutch and driving 13s should be no problem. Make sure you have everything in good shape though. A test pipe for the track is a good cheap power producer also so pick one up ( SBR has em ). There's plenty of how-to drag race an AWD on this site, so I'll let you find them, but remember to never dump the clutch. Your drivetrain would never forgive you if you did.

Rewire your fuel pump while your at it and maybe get a 190lph also. 17psi with that combo should be fine.

Thats a definate, I have most of the mods that you have and I noticed that on a 3rd gear pull my O2's dropped to .88 volts at 7K RPM. What is your O2 voltage at redline on a 3rd gear pull? I'min the proces of rewiring my fuel pump now, and I just found out that the person before me had an amp in the back and had an 8 gauge wire run a bit past the fule pump. Talk about a free mod

I noticed that you said you have a testpipe back exhaust, you can pick up a really cheap downpipe at:

http://www.exhaustdepot.net/95ec2gen3edd.html

It made the single largest difference on my car.

Honestly, if you try and murder your clutch right now,you should be able to pull of 13's, if not a rewire and a downpipe will get you there.
 
i hope your joking about holding 17psi. i have a waste gate actuator from forced performance, its a ####ing joke. after 6k rpms the boost drops below .8 bar i really wish i hadnt have thrown away my stock wastegate actuator because this forced performance one is complete crap. you cant run lower than 1.3-1.4 bar

if you had set your mbc to 17psi you would have the exact same results. i cant hit fuel cut on 17psi on a t25 so really your not gaining horse power. just spend that $100 on a 14b and you will be alot happier.

Buying a 17psi actuator to replace an 11psi actuator and wondering why you can't run less than 17psi: Priceless.

i got the actuator for free at a forced performance dyno day. the only difference between the one i have and the stock actuator is i cant run less than 17psi. i got it back in september and all i knew was that it supposedly gave you an extra 30ft tq and clained 15-20hp

i think it held boost better for like a month then it just went back to falling on its face in the top end
