ill have to get the sheet scanned but needless to say i wasnt impressed at all!!! With the mods I have I was expecting atleast the minimum of 250...

Run 1...231.22 HP 213.22 TQ SAE

Run 2...235.55 HP 218.97 TQ SAE

Run 3...242.15 HP 231.53 TQ SAE

Believe it or not my A/F ratio was dead on 13 all the way through the runs...It was run on a dynojet not sure of the exact model...again as soon as i get the sheet scanned i will post it...also i have vids of all 3 runs so ill try and get them uploaded sometime

 

Every dyno is different. Unless you got a baseline on the same dyno, you wont know if your mods did anything for you at all other than make noise and make the car feel faster. Id like to see the chart, I would have expected your hp to be higher with a good A/F but like I said with no baseline its pretty worthless to say your dissapointed. Some dyno's simply read lower than others.

 

Yeah the guy was saying his dyno was really hard to make numbers on...not sure if I believe the guy or not but I dont have a base so that's my fault there. It feels like it has more power than that but only a feeling.

 

Yeah, if you only based say a 222hp which happens frequently then you picked up 20hp. Not bad. Does the RSR replace the y-pipe?

AAM Angled Plenum Spacer
^^^^^^^^^^^^^^^
With all your mods you were expecting 250?????? you have exhaust and a plenum spacer. Count your blessings on what you got. 242 aint bad for 3 bolt ons

 

No it should be called a Y-back instead of a catback...the guy told me hes only had two cars ever make it over 500hp on his dyno...basically said it was about 15hp lower than just about everyone in this area...

 

Get an intake and you'll see 250 most likely.

 

Yup with all those mods...and it was right at 45 degrees outside so it was down right chilly

 

I just have a cone filter on it now...I could either try to fab a shield for it or just go for the JWT Pop Charger

 

Sure would like to see the dyno chart.

 

Go with JWT Popcharger, you can't go wrong seriously. Don't have to worry about hydrolock at all.

I ran 256.9 RWHP and 238.2 ft/tq. on a dynojet with those parts. It's easy to see why people get 'disappointed' modding their cars N/A. I was dissapointed with my numbers as well. This thread is common place and very representative about how disappointing N/A is. I went through it.

Compare those numbers with my 450 RWHP and 480 ft/tq with my APS TT kit. Compared to a stock Z, I basically doubled my RWHP and more than doubled the torque.

If staying N/A don't measure you gains by dyno numbers. Measure by the feel of the car and seconds at the track.

 

With no ECU Im sure you were in no way getting near the maximum potential of your mods. With less mods than you-no TB, or headers, but an ECU over you I did 262whp and 252ft/lbs SAE on a dynojet. I gained 23whp over stock, Im happy. Mods and mods wont do anything without tuning. The sooner people start understanding that the sooner they will ne happier with their bolt-ons...

 

Yea FI is the way ill be going lol...I should have the chart scanned by tonight and posted

 

Ok well i have got a ghetto style pic of the chart for now lol..it actually looks good im shocked, but here it is...

I had the ecu flashed afterwords. the reason I ran without the ecu was to get a baseline with AFRs to compare after I had the flash. Honestly the car felt sluggish as hell up to about 5000 rpms after the flash. beyond 5K to redline it seemed to pull a bit harder. I dont'think I gained much if anytihng on the reflash so I figured it a waste of time and money to redyno

I had made up my mind to go FI anyways after the flash, so it really didn't seem worth it.

From the dyno chart posted, I would guess minimal gains with a reflash.

 

i dont think i will get a reflash and hold off on utec and just save and save

 

yeah im gettin the emanage ultimate, no reflash for me, i used to be convinced that was the way to go but the ultimate can do everything the reflash can - better.

 

my thing is even with tuning im not going to pick up much...my a/f is just about as good as you can get...maybe with timing but to spend 800-1000 just to adjust timing is a little extreme to pick up another 5HP...i dunno maybe im missing something

 

well yeah you get more with timing, and if im not mistaken you can also up your rev limiter to 7100 rpm, which wont give you hp but it will improve performance, plus it sounds like you will be getting more mods eventually, which means that your almost perfect A/F probably wont be so perfect anymore, and you can fix that

and when you think about it, you cant pick up much with tuning...yes, but you cant pick up much with just exhaust and plenum spacer either, the tune will help you maximize once youve accumulated enough mods to actually make a noticeable difference in power

ah and one last thing, the EU is 550 shipped with the harness on ebay, and its straightforward to install yourself. so its not 800-1000
