Yah this is a great tool that we used for the SportZMagazine Dyno shootout a long time ago.

Made sure everything was consistent and its easy plug and play

Alagolfer and I spent part of today insulating the back of his Popcharger's velocity ring (picture above) and comparing the temperature profiles of his insulated JWT Popcharger and Z-tube vs. my insulated Stillen CAI system and Z-tube.

Please note: We don't present this info as absolute. These are the numbers we got while driving both cars throughout the day.

Alagolfer's 03.5 G35 Sedan
Air Intake System: Popcharger w/heat shield & Z-tube - Back of the velocity ring, MAS Air Flow sensor and Z-tube are fully insulated.
Ambient Temp (dash readout): 97F
A/C System: On
Radiator Fans: On or Cycling.
Water (Coolant) Temp: 190F - 210F
Intake Air Temp @ Idle for 5 minutes: 134-138F
Intake Air Temp @ 60mph: 116F
Approximate Cool Down Time: 2+ Minutes
Note: Pre-insulating the V-ring numbers - 82F air temp & 114F idle temp.

DaveO's 03 G35 Sedan
Air Intake System: Stillen CAI w/Popcharger air filter & Z-tube - System, including MAS Air Flow sensor, is fully insulated.
Ambient Temp (dash readout): 98F
A/C System: On
Radiator Fans: On or Cycling
Water (Coolant) Temp: 190F - 210F
Intake Air Temp @ Idle for 2+ minutes: 112-115F
Intake Air Temp @ 60mph: 107-109F
Approximate Cool Down Time: 2+ Minutes

Alagolfer noted throughout the day his temps were about double what mine were. For example: At idle, when the Stillen system was about 15F above ambient temp, the Popcharger’s temps were 30-35F above ambient. At 60mph the insulated Popcharger system was an average of 10F higher than the insulated Stillen system.

Next up... the stock air case with an insulated Z-Tube.

We'd still like to get info on a non-insulated Popcharger - Z tube, a K&N Short Ram, and an Injen, AEM, or Nismo system. FYI, the pavement temperature in front of the house was 155F with a 90F air temp. We didn't get it at 98F.

Great info. The temp differences will generate a noticeable difference in power.
I need to look at my stock intake setup (with Z tube) to see about simple mods to the stock intake enclosure and the grill area that'll allow for more effective intake from up high (not down near the road).

Jeff,

We can sure use more independent "real world" information for G and Z owners.

I might look into one of those trick little units that you're using. I had a software with cable setup for my previous Audi S4 that worked pretty well. It hooked into my laptop. The turbo engines are a little more finicky, so it was money well spent.

12SecZ

too bad it didn't show A/F I would buy one in a second!

Max (Technosquare tuned to 9 PSI)

it might register karman values, i know that a consult scanner can record a/f through the karman sensor in you exhaust.

That would be awesome, we have come a long way.

We used the Techtom MDM-100 on the 300zx TT and they were great. Not so much for tuning but monitoring and troubleshooting. If Idle started acting up or perfomrance changed you could usually track the issue down easier with one.

They were about $400 then.......nice to see they came down. Been looking for one.


Thanks for posting.
