Well, I'm about 18 months in to my full build and I finally got the car street tuned and on a dyno. I was honestly expecting less power, but I'll take what I can get! Max WHP - 407, max tq - 373. This was done on Sunoco 94 octane fuel.

The car is a 2004 G35 coupe with a fully built bottom end and an APS TT. For more info on the car check out: http://www.kptechnologies.com/dynos/

 

Not bad. What is your A/F kinda hard to see....how much timing you running at redline?

 

tq numbers are kinda low

 

The O2 was in my tailpipe, so I don't consider it accurate at all. I was close to 11:1 at redline (6500rpm) according to my AEM. I have no idea what my timing was, I would have to go look at my logs. I do know its a fairly conservative timing map though, as I am tuning it myself and I've never tuned a car before.

 

What are you tuning with, Ill assume you arent using the Unichip. Didnt know you also had cams...

 

I've got a UTEC. The cams are JWT with a custom grind from Scott Performance. I was pretty impressed with the car making power to redline, just as Ted had promised!

As far as my torque I thought it seemed low too, I was expecting about 370whp with 400 ft/lbs of torque.

 

what boost?

 

The max I hit was 7.68psi with 8.6:1 compression.

 

nice numbers for such low boost and low CR. turn it up!

 

Exactly, how does it idle with those cams Kevin?

 

hell no dont turn it up keep it were its at nice and safe. now you have a turbo 350z that is going to be safe and dont have to worry about much beat on it and enjoy it. My turbo Z should be done by the 18th of aug the only thing is i will be a little worry because i have stock internals. Im sure i will end up building my baby ....if i want to or not later on maybe next year when i have some more cash but if i can i will be doing the same as you built bottom end and just get around 400-450 and call it a day.

 

First off, its a G35, not a Z!

I talked to my local shop that works on my car and they theroize that my torque was so low because I don't have a boost controller on the car yet. Running off of manifold pressure I don't make max boost until 5-5.5K rpm, 500-1000 rpm past the point of peak torque.

I'll be going to 12-13psi here soon. My next obstacle is to get the UTEC to work with the APS boost solenoid, something that I've been told is impossible to do.

The car idles perfect with the cams. I had to have Infiniti bump up my stock idle, but after that I've had no problems with the idle. I will say that the car doesn't like to start when its warm, so I have to give it a bit of gas at start up. It starts up right away when cold.

 

typical responce from this guy..........nice numbers.

 

he even said he thought his own torque numbers are low... what is your problem man?

with turbo cars you expect your torque to be more than or equal to what you hp numbers are

 

that curve actually looks like my vortech curve except mine has more power from 4600rpms and upward and doesn't dip way down low like that below 3000rpms. I'm sure the lower compression is coming into play, but still that's a little odd

hopefully adding more boost and adding in a boost controller should get it looking like normal APS TT on a built engine numbers.

 

Sentry damnit! You and your my S/C has more power posts, unless you dynod'd on the same dyno with the same correction its very unfair to compare...

 

Looking at my UTEC data I would say that at peak boost (7psi) I was running 21 degrees of timing.

Also, looking at my data logs I can see that I'm going super rich at 2250 RPM and then leaning back out to where I should be, thus the dip in the graph.

 

Thats awesome Kevin! Wish I was making that much power with mine at 7lbs, lol

 

Unless you have both cars on the same dyno, same day, same environmental conditions, same fuel octane, etc, etc,...............the dyno graph comparison is NOT valid.

Good point on the comp ratio............without thorough tuning the lower static comp will hurt peak power.

 

I know the dynos aren't comparable in an exact scientific manner, but they have a similar shape with similar power numbers even if there's some % difference one way or another.
