Here is my very disappointing dyno graph I had done yesterday. Brian at APH in Markham says there should have been more HP but couldn't find any more?? He says possible bad spark plug/s ?? As the torque graph spikes should be smoother apparently?? Air filters are a week old, had a synthetic oil change done the day before. I was hoping for around 285 hp with my mods. But not even fn close ... A total waste of money and time in my eyes... Now I get to listen to the car crackle every time I let off the gas ... Omg... It drives me nuts !!!

 

Wanted ecutek tune but my rom wasn't cracked, drove 5 hours to tune shop so I ended up going with uprev tune

Mods:
-Stillen gen 3 CAI's
-Motordyne M370
-FI full CBE and HFC's
-Cusco FSTB
-Hotchki Sways
-Swift springs
*don't have a before mods dyno

Results:
269 to 274 torque and 293 to 301 HP

 

My base dyno already had all my parts installed and I put down 290HP & 272lbs/TQ. After the tuner went through a number of runs I ended up with 317HP & 301lbs/TQ. That's a bump of 27hp and 29lbs/TQ

 

Where did you get tuned Ravensminded? Your tq is pretty high.

 

Got around to having the G dyno'd today. Best run was 498 WHP and 432 lb-ft of Torque.

i gained 19whp and 9wtq after being tuned with my headers
do all your mods first before you go to gears as it will affect your dyno numbers..

 

Don't hate me for this but here are the results from an UpRev tune on my 2007 G35x. I had Berk HFC's, a Megan Y-Pipe, and diy grounding kit installed before arriving, so that is the baseline comparison. You're probably thinking to yourself "el_donks, this is the G37 forum. What are you doing here?" to which I disclaim that the G35driver forum seems pretty ghostly these days (for second gen) and besides, the car is basically a G37 Jr Also, don't mind the torque spike at the start. No idea why that happened but the max torque is more like 255 ftlbs.

 

321whp 264wtq on a 2011 g37x sedan

Not to bad for an automatic/awd! Plus 90 degrees outside during dyno

 

What mods have you done?

 

Just bolt ons. I will be swapping topspeed out with stillen cbe shortly

Z1 intake, ported tb, ported plenum, ported lower manifold, stillen headers, z1 hfc, topspeed cbe.

 

 

Got this done yesterday at Z Car Garage.
Stillen Gen 3's, FI RHFC and Uprev tune. Wanted to go with Ecutek but Rob said he's never done a N/A G. So Uprev (for now)

 

Wow that's great results for just hfc and intake. Very nice

 

306 base line OBx test pipes OBX cat back and k&n hot air intake 337 final #s

 

I am a little late to this thread.... But why not, bought my G used a year ago. Here are my SAE dyno result from last week. STD was around 300 whps / 264 tq.





Mods:
Z1 plenum
HPS mid intake hoses
injen short hot air intake
tanabe medalion touring mufflers only
ecutek (tuned by Seb @ specialty z)

Dropping in a VLSD diff with 3.69 gears in it tomorrow!

Cheers,
