Whats with all the dynos?

Im reading more and more of people dropping $200-$300 bucks for dynos. Thats money that could have been spent on mods. Then they are disappointed when they dyno 250. Then they want us to figure why its so low. Bottom line is a Ricer will still tromp you with a lot less hp. My suggestion is to dyno the car at a street light or track for $20, and save the $300 towards parts that will help your times.

Its all about bragging rights.

And usually that includes a dyno tune. Ive never seen anyone drop 300 bucks for a couple dyno pulls. Usually runs about $50-$75 for 3 pulls, and thats with a wideband.

Yep, for $300 that would obviously be dyno time plus tuning. And believe me, dyno tuning is worth it. I just got mine done this weekend and it's like a new car. We picked up 11rwhp (I'm now at 265) and most importantly the torque curve is now extremely flat and it's 30 foot pounds higher in the midrange! So my car is considerably quicker now, it's going to run at least 2 tenths quicker at the track for sure. It shifts into the next gear without hesitation and pulls so much stronger to redline without any hesitation. And even when driving normally at part throttle, you can feel a big difference. Right off idle my engine is snappier.

I highly recommend a dyno tune! Even with my car being basically bone stock it picked up a lot of untapped potential.

Ok...obviously your *** meter must be a highly tuned device that can tell the difference in rwhp even given different weather, elevation, driver error?

Do you know how many guys put parts on their cars, go to the track and run as slow or slower...."but I put parts on the car"...so what?

And dyno bragging rights...so what..sort of like bragging you got a 12" johnson, but when it comes to get busy..your limp...so what? You got ****. My old combo only put down only 360rwhp, but would lay smack to many cars floating around.

I pay $50, and if I want O2, it's just $5 more. And that's 3 pulls and he lets me drive.

The last place I had mine done did 4 pulls with wideband O2 for $40. Thats cheap. This was on a group dyno day, whole bunch of LS1's, LT1's and some DSM guys. Those $200 - $300 amounts are usually for an hour or so of actual on dyno tuning. For some cars thats really worth it to get the most power you can out of your set up.

Here locally about 3 weeks ago we could get 3 pulls for $40 bucks. That was from a mobile dyno divice and the guys came into town for a car show. Pretty good price I'd say. They really knew what they were doing also. Didn't tune cars, but added helpful suggestions to aid the driver towards more power.

Whoah, i'd never pay $300 for three pulls and doubt most people ever would, that has definatley got to be for tuning. Here its $50 for two runs. $100 bucks for one hour on the dyno and tuning. As far as why people do it? I did it because I wanted to see if my car is running what it is supposed to be and it obviously wasn't at the time if you read my post. Other than that, I agree with most people who say, the track is what counts.

There's more to dyno, than just bragging rights. It's a good source of information to help you get the most out of your car. Dyno numbers are not an indication of what your car WILL run, but rather what your car CAN run. There's a lot of variables involved that you have to figure out before your car can run its potential.
Yes, it's worth it to have a car dyno tuned.

Damn your Audi is quick. What motor is in that, a 1.8T? Just curious, sounds very cool.

IMO a dynorun is important. It is a great tuning tool. You can see the motors power band, plain in black and white. You also will see the cars air and fuel ratio, which is very important. Basicly if you want to get the most out of you motor that why not dyno it.

As for dynotunes.... The reason why they cost so much is because of the time and tools being put into it. You figure your paying for a tuner to sit there and study your engines results and work his magic, and tweak out the fuel injection system.

Im sorry but its not just for braging. Half of the time people find out things they didnt even know about the engine after a dyno run. Like, a missfire, false knock, rich condition, lean condition, or all out hp and tq loss.

What ever floats your boat.

Yep, my dyno tuning session was very valuable in this regard, as it showed me I was running too lean (14:1) and we traced it to a torn intake elbow. Once we rigged up a different one for the dyno session, we could tune it properly and get the car running the way it was supposed to, and now the a/f ratio is 12.5 to 1.
