Finally the Dyno

GollumSi · 03-25-2007, 01:11 AM

So I got the car about a month ago now and have been doing adjustments to it cause it was running a little rough. Well it's not rough now and so I got it checked out today and these are the results with about 9 lbs. boost. It spiked to like 11 lbs.

I am pretty sure that you all already know that the bottom lines are HP and the top are torque but just in case....now you know. As for the Air Flow.

I know it's not as much as others on here but I like it and it's fun. I have some upgrades that I am working on doing real soon. I am gonna go to 555inj. S4 cams, 300z MAF and a dtec system and t28 instead of the t25. I know the t28 isn't a big difference in power but it has the same spool time but is more efficient than the t25. I have a larger list of things to do to it but that is where I am gonna start. The shop I went to like the motor in the nx and said to have fun with it so......I think I will. Also, if anyone in or near Portland needs a good shop this is where I went. http://www.preracing.com/
I know a lot of people happy with their work and so far I like them a lot.

not to shabby...what is the current setup???

Holy torque numbers!

Yes, I agree - what is the setup??? I'm dying to know what kind of torque/power I'm looking at...

And what did you do to get rid of your "running rough" problem.

In all honesty there isn't much done to it. It's the stock T25 and cams It does have a stage 3 clutch, and that's about it. As for the rough running I put new plugs in it, properly gapped. New fuel filter, cleaned up the vacuum lines and that's about it. So all in all it is sitting normal. I am going to be doing the other upgrades here soon though. I am gonna go to 555inj. and fuel rail, S4 cams, 300z MAF and a dtec piggy back system with a t28 instead of the t25. Right now as it sits it's just fun to tear up my friends in it. I drive a civic also and so do most of my friends. They can't keep up. I love it. When I do the upgrades I will post pics and specs after the new Dyno. My goal is around 300 at the wheels. That will be cake with the upgrades done.

i would think with your current set up you could hold 12lbs of boost and get a little more power than that out of it.

The boost spike you experienced is unfortunately normal for a typical manual boost controller.

Otherwise it's not too shabby at all. I'd be a little careful around PRE...I've dealt with a lot of very mixed reviews.

nm. delete.

I could hold 12lbs. but the T25 is getting worked pretty hard at that point and without a piggy back to control everything better it can spike higher than reliable levels and it isn't that efficient. At least from all the reading I've done on here and from what I have heard from talking to people. After I do the changes I am gonna tune it to run at 12lbs. full time. Right now I think I will keep it down and play it safe with the motor. There are still a few kinks to work out on it. It's running real nice and strong but I need to fix a couple of other things before I am sure it's ready to go up. One thing I have learned is that it's better to run a little lower and be able to keep running rather than give it everything and walk to work.
Yeah Veil that's what I heard. I guess no matter how good they are they are still a little inconsistent. That is why I wanna go to the D-tec. Give me more control and be able to monitor the system better. As for PRE, I have heard some mixed reviews also but mainly for my friends that went in there with Hondas. Also, after talking with you and a few others. Ok well, mainly you I have learned to take what they said and check with other shops and see what they say about the setup I am talking about. I have also been going over the posts every night looking for others views on some of the equipment I am looking at and reading sheets on the different items. My biggest concern was the S4 cams. I was thinking that I could do either 2's or 3's instead. One they are less money and two do I really need that much additional torque with the numbers I have. 2's or 3's will give me another 14 - 65 depending on how they are setup and with it being a front wheel drive it gets a bit squirly with what it has. I don't know if it is the right choice 100% but so far it's what looks right on paper. What do you think about the setup idea?
