RE: Turbo Help!!! - 2/16/2006 12:04:51 PM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline yea the super afc is a good unit, but is not needed. the map sensor is not actually reading any boost because of the synapse. but, if you try to run more than 7 to 8 psi you will probably break your motor (on the stock timing) :) .........save your money cause once you get it dialed in, i have some tips for you to safely turn up your boost and crank up the hp to about 250-270 at the crank. (if running 7 psi right now you should be around 200) (in reply to mbo1985) Post #: 16

RE: Turbo Help!!! - 2/16/2006 9:57:32 PM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline Hahahaha. My accord lives. The lean condition I spoke of happens as the turbo approaches 1 psi or so. Then it goes rich like it should. I'm not sure about this, but it's kind of annoying (I still have to put in the new fuel pump). Any way... Turbo spools nicley. BOV sounds great. Aside from this minor fuel issue things look good. I thought I bought a wastegate with a 6lb spring, but my gauge has read closer to 8 (once almost to 10). I'm wondering what's up with this. Should I use the little outlet on the compressor housing to give the wastegate what it needs? I can't wait to hear the tips. Man, this has been an awesome project and I know it's just the begining. Thanks for the help so far, lightshow! (in reply to lightshow) Post #: 17

RE: Turbo Help!!! - 2/16/2006 11:50:35 PM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline yes absolutely.....the outlet on the compressor side of the turbo needs to be hooked up to the wastegate for it to operate. it doesnt sound like the wastegate is working right now. i bet those new plugs made a difference. the first thing youll need to turn up the boost is a manual boost controller. i like the real simple design of the ball and spring type heres a real cheap one. boost controller then i would recommend a cam shaft with a turbo profile on it. gude and AEBS both make a great product for around 2-3 hundred bucks. it will make more power at whatever boost level your running. also, it would be a good idea to get a front mount intercooler if you dont have one. doesnt need to be real big maybe 12 by 24. now to run more boost you have to change the ignition timing in relation to the amount of boost that you are running. it a real simple ignition system change and should cost around 3-4 hundred. you want to retard the timing per each pound of boost that you run. we can talk more about that later. you just dont want to have any detonation. your motor was designed to handle about 300 hp, and it should very safely handle 250 without changing out the rods or closing the deck. you have to get the wastegate to work though because boost creep and surge is no good.

RE: Turbo Help!!! - 2/17/2006 7:49:14 AM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline Well, thinking ahead, I installed an MSD boost master timing unit before the install. I'm the last person to want detonation in my motor. Currently, it is set to kick in at about 2 psi. I didn't realize that my stock internals could handle about 300 hp, but I guess that makes sense as long as detonation isn't present. I also have a front mount intercooler. I'll look for a good turbo cam and that boost controller. I'll also switch out the line that feeds my wastegate. Any idea about the deadspot in my fuel system? It seems to lose fuel briefly around 1 psi or so, and then like magic it's back. It's kind of annoying since as the boost kicks in, the car looses power and then regains it.

RE: Turbo Help!!! - 2/17/2006 12:43:07 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline Even though he says it can handle 300 hp stock....... dont ever take it that high..... If you change the rods pistons and rings by all means then do it, but the pressure you would be putting on the stock rings at 300hp would destroy them, just run 7 or 8 psi until you decide to rebuild the engine. Side note, if you have an auto trans. it wont handle 300hp. and at about 225hp if not lower, you need a transmission cooler. (in reply to mbo1985) Post #: 20

RE: Turbo Help!!! - 2/17/2006 2:09:15 PM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline No auto trans here, but that's still good advice for anyone with auto out there. I think my problem with my fuel system is that I still have to upgrade my pump. Other than that, things seem good for now... I plan on doing rings, rods, and pistons in a few months. Maybe when I get a week off. (in reply to marbro) Post #: 21

RE: Turbo Help!!! - 2/17/2006 10:27:10 PM    marbro Posts: 1478 Joined: 1/16/2006 Status: offline You lucky sob, Im eventually going to break down and convert my auto to a standard. And yes, I am jealous of anyone who drives a standard, which is why I frequently take my friends 05 2door accord for a spin. I love the fact that thing has enough power to chirp the tires in second gear. But I hope the fuel pump fixes your problem. (in reply to mbo1985) Post #: 22

RE: Turbo Help!!! - 2/18/2006 5:43:58 AM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline you know....your fuel pump really shouldnt cause a not smooth transition between no boost and boost. what lines are you using to hook up your fmu and your bov? you should have a 5 way vacuum 'T' hooked in between your manifold, and your STOCK fuel pressure regulator.......leaving 3 vacuum lines. one should go to the BOV, the other should go to the FMU, and the last one should go to the boost guage inside the car. the new fuel pump may also very well fix the problem, i was looking around at some other turbo honda setups in my area and they all use the walbro fuel pump with an fmu im not sure what that other guy was telling you.. if you have any other line feeding the fmu there might be some lag involved which could cause that dead spot. the setup you have should have a really smooth transition though, i think it just needs to be dialed in. and yea marbro is right i wouldnt go as high as 300 on your motor.....id definately do 250 though :) (in reply to marbro) Post #: 23

RE: Turbo Help!!! - 2/18/2006 7:47:12 AM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline I have the FMU and BOV connected to one of the vacuum ports on the driver's side of the car. It was originally capped of since it was not used. I would have ran a tee fitting of the boost gauge line (I think it's running off another port on the side of the manifold), but I didn't want to overload one line. Yeah, "settling" for 250 is probably the way to go. I don't think I would mind too much... That boost contoller looks interesting. Might be a good few bucks spent as soon as things smooth out.

RE: Turbo Help!!! - 2/18/2006 2:38:16 PM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline thats definately your problem then. you wont overload the line if you put all three on it, thats how it should be hooked up. all three units dont release any of the vacuum. just try it the t fitting is only a few bucks, just cut the line going to the stock regulator and put the t fitting in there and hook everything up on to the fitting. i bet your transition will be so much smoother. yea those simple manual boost controllers work extremely well. an expensive controller will work good too, but my favorite turbo setup is a budget one. turbo xs has a great product that i have seen in action its a solenoid that can have two different settings on it that you can change from inside the car. try that 5 way t though....you seriously wont overload the line.

RE: Turbo Help!!! - 2/18/2006 4:59:41 PM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline I haven't tried the T-vacuum thing yet. I'm noticing that when the motor goes into boost at WOT, it seems like I have less power than when I have no boost. This almost sounds like I'm running too rich. I notice if I back off the gas, the power is there. I don't know if I'm too lean or too rich at this point. I'm getting confused.... < Message edited by mbo1985 -- 2/18/2006 5:00:10 PM > (in reply to lightshow) Post #: 26

RE: Turbo Help!!! - 2/18/2006 6:22:33 PM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline that could be a problem with your pump.. but if your FMU isnt hooked up to that t fitting, then it isnt working properly....you have to get the right source of vacuum on the FMU.

RE: Turbo Help!!! - 2/18/2006 6:31:27 PM    lightshow Posts: 1775 Joined: 1/6/2006 Status: offline yea youve gotta get the FMU, the BOV, and the wastegate hooked up right if you want your car to run well. if you dont have the outlet in the compressor hooked up to the wastegate its not going to run right. if the BOV and the FMU arnt hooked up to the line going to the stock regulator then the car isnt going to run right. that t fitting is only a few dollars.

RE: Turbo Help!!! - 2/19/2006 9:56:17 AM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline Yeah, the main criteria for getting my car was it had to be stick. Mine would chrip the tires in 2nd too, even after I put good tires on. I even snapped an axle racing my friend when I dropped the clutch. And that was before the turbo... I think a prelude transmission and axles are in my future. I changed around the vacuum lines and I'm going to see how things go. (in reply to marbro) Post #: 29

RE: Turbo Help!!! - 2/19/2006 7:16:30 PM    mbo1985 Posts: 778 Joined: 12/11/2005 From: Florida Status: offline I switched the vacuum lines around, things seem to be slightly better. I'm wondering if FMU's are known for failing. It is a used one, and when boost is present at WOT, the motor has very little power. Oh well, at least it's not leaking oil...
