Just got back from the dyno. Heres my results. I dont have a scanner so I couldnt scan it.

03 track 6MT:
245hp/235tq
A/f stayed between 14 and 13. There was a little "hick-up" around 3700rpm just above 14 then slowly comes back down to just above 13 at redline.

My mods were borla true dual exhaust and a custom grounding kit. Car has 12,000 miles. Outside Temp was about 55-60.

Do these numbers look good ? I though they looked pretty good considering the 2 mods I have

what have other Z's dynoed on that dyno? What were their mods?

 

I was told by the guy there he has seen Z's dyno between 225-235 bone stock

 

cool...your car sounds like its doing well then!

 

Yeah I thought it was, i was more curious with the A/F ratio.

I ordered the JWT popcharger, should be here in the next few days

I think the next things I would like to do are definitely a cat upgrade. Probable kinetix ones, I want to avoid the raspy noises I've heard about when installing the RT ones with the borla exhaust. Also thinking about the crawford Plenum too. I want to try to avoid having to do a ECU reflash though.

 

Where did you dyno the car?

 

NE Dyno and tuning in Worcester...

 

sweet, I was there a few weeks ago and got 237/238 but there was certain things I needed to change next time around

 

Were those numbers with the mods in your sig ?? Sounds pretty good..

I am trying to figure out which cats to get now, but I dont want the raspy noises people have associated with RT's... How do you like you ultimate ones ??

Steve

 

I got alot of rasp as 90% of people do when you add any cats, its basically the resonance in the exhaust systems. Also I might add my numbers are for an 5AT and thats actually excellent for a Dynojet. The cats made a great difference too I got them from Z1Auto

 

Are there any cats out that wont produce a raspy noise with the borla TD kit ???

 

Kintetix hi-flow cats don't make that raspy sound and best price of all.

 

Are the numbers corrected? Doesnt sound like it.

 

Yes they were corrected

 

Numbers sound about right - had my 2004 Infiniti on the dynojet and the numbers for bone stock weren't bad, got my baseline:

 

Did you ever get a baseline before the Borla and the grounding kit? Is your intake stock, too? Seems like if you have true duals for exhaust you'd want to try out intake changes, see if things go up or down.

Tallyman, good dyno. Ever reset your ECU after installing the exhaust? How soon did you dyno after getting the borla?

 

No i never reset the ECU.. I have put about say 200-300 miles on the exhaust, then dyno'ed.. I will say that from the first time I took the car for a ride after the exhaust install till now, it has definitely gotten a little stronger power wise...

DO you advise resetting the ECU ?? If so, which way, disconnect the battery or that timed procedure ??

All of the cats are going to produce a raspier sound than the stock cats - stock cats are far more dense, and as such, absord lots of sound (and flow). I suspect the Kinetiz and Ultimate ones will sound similar, as they both use a similar cat
