My P11 on the dyno

Awesome bro, glad to see some life in here!!!!! she sounds good......nice numbers

Nice numbers... hopefully my RR can put up numbers like that...

Am I looking at this right?

213HP - 211Tq 2.5" DP with stock catback 8psi

226HP - 226Tq - 2.5 DP & 3" catback 8psi

Sounds really good!

No both of those were with the 3" catback.......I did a pull from 1st to 4th gear and the dyno didn't get a reading I guess on any of the gears pull except the 2nd gear pull that shows 226hp and 226tq

I wanna say this for the record.

I got my suspicions about this dyno though, im a street tuner and I learned some things about this particular "type" of dyno granted I have not ever dyno'd a car a dynopack dyno, but I WOULD NEVER EVER TRY TO ATTEMPT TO TUNE OR MAKE CHANGES TO MY OWN TUNE or ANYONES ELSE'S CAR on this "type" of DYNO from what I have seen and witnessed with my own eyes.

The loads this type of dyno place on the engine are not even close to "realistic" and if you were to tune a car strickly based off what a dyno tell's you will would wind up with a tune that is totally different on the street.

I think in the near future i'll try a dynopack. Remember I drive around full time with my wideband so I know exactly how my car act in vacuum/transition/boost and what my consistant AFR are and when im on this "type" of dyno NOTHING is representative of what I see on the street where it matters. But its good for numbers perhaps a dynopack dyno is where its at.

First the dyno needs to be setup for the gear you are doing the pulls in. I dont think it is the dynos fault, it is the operator. Did he setup the dyno before you made any pulls to match your RPM to what the dyno was seeing? When i was on the dyno he took some time to get things setup and it was exactly like the load values i see on the street. Weight and RPM have a factor and if not setup correctly you are not going to get good readings.

I don't think he did, cause I know what my own AFR's on my wideband and do my own logs and every time I been on this dyno my wideband reads about .75 - 1 AFR leaner consistently. I don't rely on the readings of the dyno's wideband cause I have my very own wideband installed full time.

So where your numbers suppose to be higher?

I use this dyno all the time and a few others use this dyno all the time. It's not the hero pull dyno jet that you hear about on the internet lol. There is no setting up on the dyno jet like you can on the mustang dyno. If you go to church those numbers will be way higher.

The one major thing I don't like is how on the dyno whatever load is being placed on my car is enough to make my WOT AFR 1 whole AFR leaner vs driving on the street, this is the sole reason I choose not to tune on this dyno......and the same wideband I did my dyno pulls on is the same wideband I have in my car full time so I know the difference, im very familiar with the behavior of my wideband in all aspects of driving and WOT and the very first thing I noticed was how lean my WOT pulls got on the dyno vs street.....~1 whole AFR leaner is a shit load of difference. Also I don't know if this is normal but I don't think a car is suppost to move up and down on the dyno like your going over speed bumps I wonder if something is wrong there cause I know I don't have bent rims...did you ever experience that?

Never had a problem like that with my wideband on that dyno. It reads the same on it as it does on the street? what kind are you running? I'm running the Zietronixs Zt2.

Yea that was the first thing I noted I been there twice on that dyno and probably did at least 20 or slightly more pulls total, I know Reggie and Ivan been knowning Ivan since he was a lil dude lol..........I run the Innovate Motorsports LM-2 wideband.

Have you tried virtual dyno with your runs? I converted my AEM logs and went back to the dyno and it's pretty damn accurate, I was with in 4hp of my virtual numbers.
