My VD is about what buraQ is... Not sure what his dynojet numbers are.

He said his VD TQ was like 630ish

Edit: We don't have the same inlets, you and I.

VD is a great tool for tuning if used properly.

VD is a terrible tool for claiming XXXwhp.

Some people seem to forget this.

you must not read very well. BuraQ posted already in this thread about his VD. He then went on to show you in another post why your VD was reading high. Get off it already, you arent making 500+whp. If you are, go on a dyno and if you are, ill pay your dyno fees.

Quote:
....and that - my VD of the 530 was a plot for a bigger plot to show how VD #s can be inflated even if the numbers are entered in correctly and the VD was configured to an actual dyno, which will need to be supplemented with logs as most of the people in this thread have done.

Logs will show you really quick why the VD is showing high if in fact there is an inflation.

I just don't want people getting the wrong idea to trust in VD #s, they cannot be trusted until it has been confirmed and configured with a real dyno and no wheel spin and/or RPM spikes that contribute to inflation on a VD

If not confirmed by a real dyno a VD is only good for point A to point B difference when increasing power provided there is no wheel spin or RPM spikes and the data is entered in correctly.

I'm definitely not going to post my VD in this thread cause it will be misleading to the newbies

Stock inlets?... What!!! Either way i did not say you didnt make more power than me. You probably do and your tune is probably more aggressive. However it didnt make your VD any more accurate.. In fact if we go by your logic i make more power than you do with only 18lbs of boost... In 4th gear i made 6xxwhp on stock turbos and stock exhaust lol.. So sure if thats more comforting continue with the fake numbers.. Honestly not trying to change your mind. Just sharing correct information

Agree. Was simply posting my VD and the power difference in tuning.

Hence, why I didn't make a thread claiming highest HP lol.

He can try to fool everyone but he cannot fool himself. He knows the numbers is inaccurate so its pointless at this point.. Waste of a good thread.. Only takes 1

Can u imagine how many blown up cars there would be had tuners take your same logic?.. Manipulate the dyno, give fake numbers, tune on fake and dyno again lol..

You definitely don't know how to use the VD then. Even the guys that don't agree with me, know the VD is pretty accurate if you put in the right info.

Let me see that VD lol

you didnt show any differences, all you showed was a high hp # VD.

If you had shown a before/after comparison or a vs stock comparison, no one would have had an issue.

Heres a good way to show how to use VD. The Stock Baseline run was calibrated to an actual dyno run. All other runs were done in the same location of road. Shows actual power increases from run to run to run.

Don't be mad, because, your car didn't make 500hp on the VD, like you thought you were gonna do, in your inlet thread, that I said you wouldn't make. Looks like you only make about 450whp, since you only made 490 on the VD lol.

Pfft i sure dont care.. If i did i wouldve done like you and lie about my numbers.. If i only make 450 its also fine, ill just add meth n more e85 and mods vs changing a VD to say it lol... Nice try lmfao..

Edit: and if all else fail i could upgrade turbos.

Not to keep harping on this, but how did I lie? And the car trapped 122 after this VD.

Thats not 500+hp. Know an auto with meth that trapped 121mph and that wasnt 500hp lol.... 450's maybe.. U lied because u put the wrong variables in the VD to manipulate an incorrect estimation of your cars value... I just dont see how even with other folks posting proof of a side by side comparison with a real dyno that you cant just let it die and move on that your VD was inaccurate.. Its ok small mistake on your end. Instead of trying to fight it down just move on dude. Its wrong /thread

I'm not sure what the issue is with this thread. No one should be arguing about how much power this car is making because your opinion is nothing more than that. Bottom line, it doesn't matter what Virtual Dyno is saying, it's just for fun... nothing more.

My opinion is this car is making 460 to 500 whp. Regardless of what the Virtual Dyno is saying, it's really cool that the car is trapping 122. Trap speed is a good indication the car is running well and making a lot of power for a stock turbo car. Virtual Dyno is a great tool to see how the power is being applied while tuning.

jtswole just needs to hit the dyno to validate the power.

My car is full interior, full tank fuel , heavy 19" wheels, 200+ driver= around 3750 on VD

Tire diameter is 25.48 on VD

Not sure how the variables are wrong.

I'll post a VD on the "stock" map and see what it makes. Once again, I'm not saying this car makes 517 on a dyno and never said that... Just to clarify.

To get numbers, id rather get trap speed numbers, as those don't lie. Not every dynojet, is accurate, either. Trap speeds don't

A local guy that made 460/500, trapped 122 with a stripped out auto e90 that weighed 3400lbs with him in it.
