I have an out of the box GT2871R and it holds 20PSI no problem with my Greddy Profec Type S...

 

[IslandFocus]

I must have some other issues then.

 

[focusownerskid]

Actually, we made 396 WHP with an out of the box Garrett GT2871R. The Garrett engineers were surprised, its not really rated for that kind of power at the wheels. And actually, there is more power there. We have to try a couple of things that have come up recently.

That was with 100 octane, 26psi, built engine, and our FocusSport turbo kit on a drive-by-wire Focus with the factory ECU. Oh and internal wastegate for all you haters. :lol:

Oh snap!

sorry it is good of at least 396whp. that is what focussport made with it on their street tuner challenge car!

Your talking about 2 totally different engines he has a zetec not a dura it will not make 396 on a zetec no where close

Blah blah blah... do you know who you sound like?

I bet randy knows

From everything that I see those two engines respond very similarly. making very close to the same power with comparable setups.

 

[turbozeteczx3]

ya your right ja-red what was i thinking yes there exactly the same have a good day ps FJ a joke

 

[Ja-Red]

I'm just saying if a 2871r can do 400 on a duratec you can do it on a zetec, its rated for 460 at the crank. We are not talking about a honda v-tec motor or anything.

hell orangesvt or whatever he is over here did 360whp on a turbo that is only rated for 360 Crank hp

Randy knows more about tuning a focus than, well... anyone but he is not re-writing the book on turbocharging

 

[IslandFocus]

Well guys, I got the rpm signal hooked up on my Eboost2 today so if all else fails I will just adjust for the drop-off with the "rpm correction factor". Don't really want to start messing with that just yet though. Need to find the "real" culprit first.

 

[polarisman14]

turbo, if fj sucks so bad then don't bother "gracing" us with your presence anymore.

William, definitely find the issue first--might be something as simple as a loose vacuum connection (if you are using brass fittings maybe it isn't screwed in or sealed tightly enough). That'd help to explain the randomness of the problem.

 

[turbozeteczx3]

im not anymore ill just watch someone mess up. i really dont care

 

[FSWerksVP]

im not anymore ill just watch someone mess up. i really dont care

Whats the problem here? Relax man, its just a discussion.

 

[IslandFocus]

Anyone else use this turbo on a Zetec motor?

 

[turbozeteczx3]

Whats the problem here? Relax man, its just a discussion.

Hey randy i dont really know you but ik you do some great work i would jus hate to see someone with a zetec get this turbo and be disapointed like islandfocus is. turbos are not cheap and the zetec engine doesnt have the best combustion chamber so it doesnt produce the same output that most engines do so when a turbo say rated at 370whp for our cars its like its rated at 320 or less depending on the trim and lb. per minute. thats all

 

[FSWerksVP]

I hear ya. And actually all GT2871R turbos are not equal. The part number we used seems to work extremely well and better than what William and other have used. There are some differences.

 

[turbozeteczx3]

ok cool i have never used garrett or the t28 style turbo i have right now the turbonetics GT-K 450 and love it so far but just so everyone knows what the good garrett turboes are could you post the part numbers for everyone else or if not they can just call you

 

[IslandFocus]

I think the one I have is rated at about 400hp whereas the one that Randy those use is rated at about 460hp I believe. I actually ordered the one that FocusSport uses but Xios sent me this one by mistake and it was too much trouble to send it back. Nevertheless, I seriously doubt that it's the turbo because now I can't boost more than 5psi max. As I was doing a WOT test yesterday, it went up to about 15psi or so and then suddently dropped under 5psi. I will try to do a boost leak test by weekend to see what the deal is.

 

[FSWerksVP]

Do you have some custom intake manifold? I don't recall.

 

[IslandFocus]

I have the Ford Racing Intake Manifold.

It won't go over 5psi? Have you inspected the turbo yet?

 

[IslandFocus]

That's correct, it won't go over 5psi. What exactly should I look out for on the turbo?
