Dyno results Disappointing.

[03_silver_coupe]

Went and got my car dynoed at a import shop in town. I know but it was the only place I could dyno at.

This is with 2.93, Diablo Chip, Bassani X-pipe, Magnaflow Catback and K&N.

They don't even do a A/F ratio. Is there anyway to tell what it might be by the graph.

One other thing, the temp is like almost 100 degrees today.

Sorry about that. Can anyone resize that. I have no idea how to. Computer retard here. Took me forever just to scan it.

Go ahead and use this one or delete yours, whatever..

 

[Juiced-03]

wow those numbers are low! who burned your chip? you should almost have those numbers without the chip and pulley!

 

[Bingo13]

What type of dyno and did they tell you the smoothing factors used?

Here is the resize-

I was a tad disappointed. I had 389 with just a x-pipe and K&N before. I got the chip from Rick. I will go back to the original place I dynoed at the first time before I bug Rick about it.
It was a dynojet and no they didn't tell me about the smoothing factors.

It was weird. My first pull was only 400. Then 420 and finally the numbers up. I thought the HP usually goes down with each pull ?

You need to go back to the first dyno shop. I doubt they had the dyno setup correctly based upon your first results and yes heatsoak will cause the numbers to drop after each run.

Huh? 422 with only X-pipe, catback and intake? You're kidding, right?
:lol1:

 

[CobraBob]

With your mods and a good chip you should see at least 440 rwhp. I have to believe the chip is bad.

 

[coleman]

with a 2.93, you should have at least 450 RWTQ ...

come over here to Kwik Kar & for $30 you'll get 3 pulls w/ A/F!

I got 439/405 with a CAI and exhaust. Something doesn't look right - even in 100 degree heat your torque should spike low then drop...

I think I know what your problem is! Mine droped from 446 to 415. The reason was my belt was slipping like a demon. My dyno chart looked just like yours. When I changed pulleys, ( 3.1 to a 2.93) I switched to a Gatorback belt from a NAPA. The Gatorback was slipping real bad, the nubs on belt where rolled over from slipping.

Or Maybe its the Dyno he was on....try & find another one just in case. This way u can make sure its not the Dyno.

good advice!! maybe get an idler as well! :idea:

 

[coleman]

yeah, LR 01 Cobra, what size belt are you running 03_silver_coupe?

Juiced-03, DD2000GT did get 439 RWHP but with a CAI, MAFterburner, X & cat-back.

 

[bassin247]

The mafterburner is a huge difference.

I got..

390/368 with drop in K&N/silencer delete
398/390 with X pipe/catback/drop in K&N/silencer delete
410/390 with X pipe/catbackdrop in K&N/silencer delete/Accufab TB
434/400 with X pipe/catback/9'' K&N/C&L MAF/Accufab TB
411/375 with X pipe/catback/headers/9'' K&N
426/390 with X pipe/catback/headers/9'' K&N/C&L MAF

I do agree those number should be higher. I would expect to see something in the 440/450 area.

What kind of dyno was this done on? That will be a big difference as well.

Running the 740. I will go one day next week to the kwik kar during lunch to see what it puts down there. I was hoping for 440 also.
Paid $65 and didn't even get A/F at the import place (redline) in Arlington.

2.93 wound be around 450hp & 460tq area.

Well how does it feel when u floor it? Im sure that Pulley should of raised the TQ to 400+ at 2500rpm. Cant u tell the diference?
