Just got back from the dyno and now make 492 HP/514 TQ with 2.8 upper only

[digital911]

Just got back from the dyno and I am really surprised what I found out.
Prior to me going to the dyno today, my car was a virgin, that is it has never been tuned nor had any pulley work done. Motor wise, it only had a K&N intake, and new plugs. I bought the car last May and I am the 2nd owner.

When I got it to the shop, they told me I had a Magnaflow X pipe and magnaflow mufflers, so that was nice to know.
Then they put it on the dyno and tuned it. The car made 492 HP w/ 514 TQ.
It has been raining here last two days, so I wasn't able to fully appreciate the power. But on the way home, on the interstate, a suped up 370z got on side me and wanted to race. We were doing 75 mph. I dropped in 4th and punched it, the back end came out and I almost lost it! I didn't think that was going to happen. It scared the sh*t out of me. I will never do that again in those conditions. Thank goodness t/c was on. Definitely a lot of power to do that in 4th gear going 75 mph, it wasn't raining but the roads were damp. I hope that it will be dry tomorrow so I can enjoy the new 80-90 HP my car has.

Let the bashing begin...... Hahahahahahaha

 

[redfr03svtsnake]

i'd say this for sure based on your graph- ur shit is gonna be toast in a matter of days/weeks after looking at that afr

 

[digital911]

12.0 - 12.2 A/F in freezing cold , my guy says its going to be fine.

id get a second opinion.

 

[digital911]

where does your A/F ratio run at???

 

[Brutal Metal]

Have you ever heard of IRFANVIEW? Edit the fricken picture size down and get ready for the bashing on the 492...And least the tuner fattened up the fuel tables on the blue run, the first one was ugly!!

By your story it sounds like your car might have been moded (posibly ported) and then returned to stock to draw in an unsuspecting buyer for a sale...

Either way enjoy the car and dont do anything stupid like floor it in the rain again so you can crash that baby..

 

[XyX]

ruh-roh......

 

[froggerlives07]

Yea it was either modded before or that's a happy dyno..I made 451rwhp with just a 2.81 pulley magnaflow exhaust and o/r mid pipe

 

[fiveoh2go]

What are the SAE numbers? And like others have said, you need to get that A/F ratio adjusted.

Soon.

 

[V8DER]

i can't read the numbers on the Dyno sheet. can u enlarge? haha j/k:coolman:
Some motors are just animals from the factory but that does seem pretty high for only a 2.8. Could be possibly a ported eaton. A/F Ratio on the graph is right around what it should be 11.5- 12 on the red pull. what was the duty cycle on the pumps? ,Mass air? Had to be close to maxing them.

No I will never do that again, 500+ pounds of torque takes some getting use to....

The car definiately is not ported unless I am totally missing something, the only thing the car had that I wasnt aware of was the magnaflow xpipe and mufflers. Now I need to spend money on upgraded IRS and tires!

How do you know for sure that its NOT ported? Did you take the blower off? Also 14.6psi of boost is quite a bit for only a 2.8 upper. Avg is normally 12-13.5psi. Also wondering if it's SAE or not?

 

[wudy]

If its a ported unit, it might have a serial # stamped on the bottom of the case.

NO this dyno HP/TQ is to the tires!

No I didn't take the blower off to see if it was ported. There are no signs of scratches, nor signs of bolts being removed anywhere on the motor. It was mint when I got it. The car only had 16k miles when I got it. I would think it would have been pulleyed and tuned if it was ported.

Also, my blower is not nearly as loud as the video clips I have seen of a ported blower.

I don't know if this matters, but I received a paper in my car that said:

Is this visible without removing the unit??

Take the plenum off the blower and look inside the inlet of the Eaton. If you can see anything other than casting it's been worked on.

Can you please make the dyno pic smaller? thx

Umm I realize it's to the tires, that isn't answering if the tuner gave you SAE numbers or STD numbers? STD numbers generally are 4-5% higher than the SAE corrected numbers. Either way have fun with it.

No way thats just a pulley. Has to be ported. Or someone played with the roller weight to make it look like more.
