Dyno Results for I/E/P/Cats.
Hey all, I finally got all of my Dyno sheets (.jpg format ) from my shop. It has stock, stock vs JWT pop, JWT pop vs added RT Cats and Pulley, and then another with a Nismo Exhaust added. It gives a good idea how individual mods effected MY 350z. I can email them to someone who can post them for me. I have been having trouble attaching files.
-peace.

Here is some links
Thank you for hosting them for me.
Stock versus JWT pop charger added

Next added RT Cats and Unothodox Racing Crank Pulley

Next added Nismo Exhaust

With all mods, by itself

These were all done at the same shop ( dynojet ) within 18 months, and 17,000 miles. I now have 22,000 miles on the car.

Thanks guys. Yes I can feel and HEAR a difference. 
Especially adding the Nismo Exhaust to the RT Cats. Loud. but cool. I am going to the Drag strip on Friday, I will see if the power difference = better times. And, if I can beat my best time stock of 14.0 @100.

The correct way to go about this is not to look at the 'absolute' number, instead focus on the 'delta' value (i.e. gain). Since he had each mod dyno'd on the same machine ... the margin of error wrt 'delta' should be very reasonable.
All in all ... he's gained 23hp, which is believable. Assuming 289hp starting point ... he's now at approx. 289 + 23 = 312hp range (at the crank). He'd likely shave off ~0.2 seconds at the 1/4-mile strip w. that gain.

This is the best dyno post I have seen yet. These numbers are as reliable as they could be baring changes in atmospheric conditions and tire pressure differences between runs. I am surprised that you picked up HP each time. I guess this shows you don't have to have the TS reflash. It gives me some hope that NA mods do make a little power.

Thanks again. I have been doing all my research on this site for 2 years, its about time I contributed some data. =] I was thinking about resetting my ECU, with the techo procedure but haven't. Hoping JWT comes out with an NA chip someday.

Nice gains. Hopefully we can get some more dyno sheets posted for comparison from a variety of mods. I will post a dyno with jwt pop charger, jic y-pipe, rt cats, and kinetix plenum this weekend, as well as the effects a reflash from Altered Atmosphere on those mods.

I didn't pay to have it after the Nismo exhaust install ( shop charges $20 more for A/F ratio ) Before the Nismo it was at 13.0 from 3500 rpm up, dipping to 12.8 at 6200rpm. My tips are already black after 3 weeks, so I don't think its to lean.
Props. Thanks to Performance Nissan for all the parts and great service.

Like someone said before me, GREAT POST! This is more proof that the popcharger really is the best bang for your buck. Good luck at the track!

looks like someone else hosted them first....I'm VERY impressed with the gains that you got with your mods. Especially the 10whp from the popcharger. I've got a popcharger and am installing helix test pipes tonight and I'm going to dyno the car pretty soon. My stock numbers are in my sig...hopefully I'll see gains too!

If you are planning to get an ECU flash anyways, it would be great if you posted gain for ECU flash on these mods. Thanks again for post, nice to have real data that many people can use...

Thanks BriGuy. Damn look at the stock times in your sig. You need to give tips on how to lower 60ft and 1/4 times for us people that apparently launch and shift terribly
