That's too bad ... I missed the event! I had to be somewhere else. I'm glad everyone had fun. Shawn at Church Automotive Testings never disappoints. Props to Tony for setting it up. Sorry, I was hoping to help ya out.
Congrat to AJ (Zazaracing) for making the 280hp dynopack club. That was the car's way of saying "Thank You" ... for taking her to the THX723 track days!
Klumzyee,
Nice bone stock '05 6mt number. Looks like peak power of ~270hp ... about what I would have expected. For reference, bone stock '03 and '04 6mts measured approx. 260hp. BTW ... the green run has a false spike at ~7600rpm (a DynaPack anomaly that happens every now and then). Your best run is the RED and I'll bet that was your 1st pull!
I didn't get to read all the posts nor the time to go back and read them all, but I thought I saw someone mentioned getting 275 ft-lbs. torque from a 5AT. Don't fret about it. That is the AT torque converter slipping upon initial WOT load and should be disregarded.

Hey guys,
Great meet! I got to dyno my car and check out other G's/Z's. I was pretty happy with my numbers. My best HP number was on my second run: 259.4 HP/247 TQ. I plugged the numbers I got from the tech into Excel. That way I could overlay the HP & Torque on the same chart. Tony, the files I got were regular space-separated text files. Maybe you can get Shawn to e-mail you the "normal" text files.
I noticed on Klumzyee's HP chart looked very similar to the Z's I saw yesterday. It doesn't have as noticeable a dip around 5000 RPM, pretty much keeps pulling all the way up to redline.

Dynapack Printout
Here's my print out... end of day 3rd gear pull - morning run was 4th gear (not attached) but I think Shawn may have done the first pull on this run in 4th also to see the difference. Otherwise I don't know why the first pull was so low (bottom faint line). Top two are definitely 3rd gear.
TQ is weak! Does anyone have any suggestion to gain torque? (other than torque converter).

Be careful with this. A TC will not necessarily gain torque if oy go with a very high stall. TC is a fluid coupler, so the higher the stall, the more slippage the thing will inherently have. If oyu want to make more torque, you will have to make it as low a stall as possible, which would on the other hand kill your launching ability. But yes, at launch, with higher stall TC, you will be able to put more torque to the ground AT LAUNCH ONLY, once yo uare up and moving, there is a net loss of efficiency compared to a lower stall.

Hey all, thanks for coming out, it was a pleasure to see some familiar faces and meet so many new owners.
I get to work with a lot of different owner groups and the G35 crowd is among the top 2 or 3 in terms of courtesy, maturity, good attitude and intelligence - IOW, I like working with you guys.
Mike, the lower hp plot was from your earlier 4th gear run. It is interesting to note than on both 5AT cars we tested in 3rd and 4th, the plots were similar in both gears up until about 4.5k-5k where the 4th gear numbers fell off of a cliff. Interesting stuff to be sure.

Shawn,
I am curious about the difference between 3rd and 4th gear with the autos as well. On my pull it looked like 4th was 5 hp higher from 4k to 5.7k across the board until the drop off at 5.7k.
I want to slap on a different exhaust and then use 1-2 hours of your time on the dyno to try and figure it out. Oh, Clint said to put it on his account. j/k!
Thanks,
Eldridge

Shawn,
Good to see you on the boards, and thanks again for hosting a dyno day.
As you remember, we saw a 10 HP increase in my car going from 4th to 3rd gear when testing Tony's spacer. Maybe next time we should test 2 or more AT cars on the same day to see what kinds of differences are seen between the two gear ratios.

BTW, is there anything you can do to help me straighten out my AFR?... It's all over the place. I'm hoping to smooth it out across the entire RMP. If so please shoot me a PM so we can set something up.
Thanks

Thanks!

No, I havn't been able to open them yet. They certaintly won't open as an ascii file and can't be imported into excell. I need to use the disk Shawn gave me to start the process but havn't had a chance to install it yet.
I'll get on it ASAP!
