terrible time on AWD Turbo

[marcelo_caz]

Theres no point for us to give you advice if you throw the advice out the window. Those expensive plugs become a hot spot in the cylinder. This increases the chance of knock. When you engine hears knock it reduces performance to keep save itself. In addition to robbing power, you could be creating additional stress on the car which in turn is wearing those piston rings faster.

I don't know what you mean by "open the head." Are you talking the head off, or just taking off the valve cover. Either way, if you are replacing the valve seals and you already have 3g lifters, then go ahead and use them. If not, clean your factory ones and they will work just as well.

As for the performance issue. I ran a 14.6 on a near stock AWD Talon, the car only had a K&N intake, MSD 8.5mm ignition wires and the downpipe was broken at the flex section with free mods done, but I will still running the stock boost controller.


You listen to the senior folks hear and you will get your car up to par and running good times. But when you throw our advice out the window, then you make me think why bother.

Before you go racing the car, you need to find out why you are loosing power 16's is crap for an AWD DSM. You obviously have a problem.

Now are you willing to listen? Or are you going to do what you want anyways?

Im not throwing adivise away, im even making a list of mods to do based on everything you guys are saying here in the forum. The spark plugs, if the NGK BPR6ES one are the best like everybody is saying, I garantee you that these NGK BPR6ES are already in my list of mods.

Open the head im mean by taking the valve cover off to change the seals, and I already have the 3g lifters, I bought few months ago, and I was just saving them for the right time.
the reason im opening the head to change the seals its because my car is burnning too much oil, i did the compresion and it was ok.. so the best guess was the seals.

Im even going to change my O2 sensor, and the knock sensor.

Im about to put the EVO III manifold on it, because my stock one just cracked.

So im probably doing all this at the same time.

And sorry about if it looked like I didnt care... im new to this type of car, dont know much about it, and im basicly "you guys are saying, ill belive"... who am I, a 16s guy comparing to you guys that runs 13s and lower.

Your driving is in need of practice for sure. It took me a few trips out to the track to get my 60' times into the 1.7s on street tires and I still should be pulling faster ones with the aid of the dsmlink dual stage rev limiter. Practice helps as I have gotten better every time I have gone to the track.

Yeah, I need a lot of practice, This was my first year on a drag strip. It was when I finally got all the manitence done in the car, the season was almost over. SO theses runs I can say it was kind like test runs. Not good runs, but it was fun.

Awsome... good to know this things.
I put a walbro 255hp on my car like 3 monrhs ago.
About the injectors, that is something that I really want to do maybe around spring, but I dont know if I get a 550cc or a 580cc. is there any major difference?

Is the apexi AFC helps on my fuel cut? how does it works?.

The air intake stuff, im probably going to work on those when I put my FMIC in, that will be probably on the summer hopefully.
heuoehuowhew


but thanks fot the tip... im gonna keep that 1.7 in mind.

You should really do some research. All of your questions have been answered MANY times before.

First off, did you hardwire the walboro 255HP, or did you just install it reusing the factory wiring. See: http://www.vfaq.com/mods/pump-relay.html

550cc vs. 580cc injectors are a 5% difference per injector -- you could have calculated that yourself. Otherwise Fuel injectors - S4Wiki can tell you that. There is ALOT of information on this topic.

An Apex'i Super Air Fuel Controller (S-AFC or commonly called an AFC) has been around for more than 10 years in some form (AFC, S-AFC, SAFC II, AFC NEO, etc.). Do a search. Google it, VFAQ it, DSMTuners search it, etc. They all have HUNDREDS of answers, as well as the previous links I have given you --

Sorry about that.. I forgot to post back, I was reading all the links you send it to me, it helped alot. Good info's.

Oh the spell chack was cruel, English is my second lenguege, im still getting use to it.. but ill use it.. it will help me with other stuff too.

The injectors I just asked, becuase i dont know much about injectors.

But thanks for the infos its healping a lot.

First off, the spark plugs are OEM equipment -- they are not mods -- it is maintenence.

Second, did you change the valve cover gasket and spark plug gaskets :

Finally, you said your compression numbers were "ok", what kind of numbers were you seeing, and how did you specifically do your compression test?


As well, I didn't mean to be cruel by stating "use the spell check", I do understand as I speak Spanish, but I am also very aware that if I write in spanish, I spell it properly so I am not confusing the person who is reading it.

Lots of good info here, like people have been saying start with the basics like boost leak test, pre turbo exhaust leaks (said your mani was cracked & your replacing it, which is a good move). With the age of the car probably a good chance both the knock & O2 sensors are bad (looks like your taking care of those as well) & the knock sensors sometimes tend to be torqued in to much as well, makeing the sensor more sensitive to knock, so be sure to torque it properly on install. For the plugs (not sure if this was already answered & I missed it) but which NGK plugs did you get? The most common mistake of newbies to our cars is to get a nice expensive set of platinum plugs (yes I did it as well), thinking they will perform the best. While they do in some applications (mainly for longevity) they don't in ours. They tend to miss fire & give bad performance in general. Our cars like the cheep copper NGK plugs (part # mentioned above), stick to these & once you start getting more mods & running more boost you can get a "cooler" heat range of this same style of plug. These "expensive" plugs that you have may be part of your problem & is why people are telling you to swap them out with the ones that have been recommended in this thread. As for the lifters, they can probably be cleaned but if your in there anyway their not all that expensive & it will prevent false knock from lifter tick happening in the future. A logger is always a good idea to give you a much better view of what exactly is happening internally with the motor & the attached sensors. As it was said you also need to work on that lauch, that alone will have a big impact on your 1/4 time. You shouldn't have any issue seeing a 2.0 60 ft (& with practice should be able to get it lower then that). The amount your slow on the 60ft usually works out to be about double at the other end. So for example if you pulled a not that aggressive 2.0 60ft vs the better 2.43 that you did pull, your times would have been .86 seconds quicker.

What I ment by "list of mods" is that when I start working on something in the car, i am going to do everything at the same time (spark plugs, spark plugs wire, O2 and knock sensor, and all the other stuff). All the manitence on the car is good, I did a full tune up about 4 months ago.

The head gaskets, I got new ones when I bought the car, because I had to change 8 valves (caused by some one putting the timing belt wrong). But now that I am going to change the seals, and lifters, i will put new head gaskets again. Spark plugs gaskets im not sure, but its something that im going to look too.

The compresion numbers I dont remember what they were, but who did the test was a local DSM shop, probably one of the best ones around English Racing.

If the platinum are the expensive ones, that is probably the one. Now im worried about the spark plugs, I might change them this week.

I didn't see anyone mention it above, but with that 255lph fuel pump are you using a AFPR? I believe it will flow too much for the stock FPR.

 

[snowborder714]

I would suggest it, especially since they're only about $2 per plug. Quick and easy fix.

Good point.

The OP is a 420A turbo car. Their fuel setup is different and I believe they don't need an AFPR when installing a 255lph. Some do go with an AFPR and some go with an upgraded FMU, I believe. I'm not a 420A person though so I'm not sure how it works exactly.

well.. I have no idea from what you guys just sayd, but I know its not my case.

 

[SOADweskey]

Just to clarify for you the 420A motor is in the 2G non-turbo cars and for some reason his head was elsewhere and even though your thread is about a 1G AWD turbo things got crossed. I blame alcohol.

I know how that goes, my wife says some wierd things when she is studying...



So marcelo, what about the AFPR (adjustable fuel pressure regulator)?

I dont have that. I as told that my fuel pump dont need one because it is just the 255lhp, and not the 255lhp high pressure.
Is that true, or its better for me to get an AFPR too?

And my fuel pump I just took the sotck one out and put the walbro in.

Either 255lph fuel pump (high pressure or not) should have an AFPR installed with it. The stock FPR gets over run.

I would suggest getting one as soon as you can.

I didnt know about that... Im gonna save some money to get one than, but its not some thing that I need for right now right? Can I still live a few months with out one? Im broke.

Yes, you can live without one for a while. But I would put that towards the top of your list of parts to get.

[marcelo_caz]

Done... its there.. first one of the list.

One thing that I wanted to know about the walbro is that if I install a walbro fuel pump, like mine, do I need to rewire the whole thing or I can just leave it the way it is?

Rewire it for peace of mind. It's too cheap and easy to skimp over.
