Anybody see any issues with this? Have the opportunity for this but wondering if it's going to give weird numbers. Guy asked if I knew where to tie down the car since he said the front wheels would have to be spinning as well.

Makes me assume it will put up some low numbers though.

You can run a RWD car on an AWD dyno... you just disable the front roller. I've had my V on one twice at AWE Tuning in Willow Grove, PA. They specialize in VW, Audi, Porsche... so they have all 3 types of drivetrain on it.

Are you tuning it yourself? Because if the guy doesn't even know how to tie down a car, I wouldn't trust him to tune it.

dyno's are tunning tools not ego boosters. you want to play the numbers game find a dynojet.

This guy does almost exclusively subarus and evos I believe for tuning. Just getting some baseline numbers before I go to a guy who specializes in LS motors for tuning. Thanks guys.

are you going to go back to the same dyno after ?

what do you mean by the numbers game, find a dynojet?

If he doesn't even know how to tie the car down, I wouldn't even have it dyno'd there.
Dynojet.

Alot of guys when they mod there cars just want to see that peak number so when they're around the camp fire they can say how much power their car is making, dynojets read higher then mustang dyno's.

You will be fine, The math for hp is calculated to make it close to the same if it uses all 4 wheels or just 2 wheels.

If it is a chain driven front to rear roller set.

If it is just a free floating 4wd dyno, then it will just use the back wheels and again it will be close from either configuration.
The software compensates..

why not just do a baseline run before ur tuner changes anything the same day? then you will actually see your gains in the same conditions and day.

This is an incorrect assumption, and was afraid you were referring to the numbers.
Believe it or not, dynojet manufacturers different models.
The 224xlc is capable of both eddy current (same mechanism as the brand Mustang) and inertia.
Eddy current is great for constant speed tuning, which brings me to my second point, a dyno is a calibrated tool which can be used for many things other than just WOT. It also requires a competent operator to understand how the environment sensors work as well as understand the various correction factors. (if any of these are off, including maintenance on the dyno itself)
These are the main reasons why there are so much variances.

e.g. it was 'hot that day' or people that use Correction adjustments (e.g. STD, SAE, DIN) on psi wastegate regulated turbo setups (which you are not supposed to do) are improper understandings or use.

Just to clarify, your statement, only refers to the difference between inertia and eddy current drums, not 'all dynojets'.

lol, like seconds after I discuss the 'hot day' or next day misconception.
This is irrelevant as the change in air is calculated for the adjustment to bring to a standardized baseline. e.g. SAE. is a standard J1349 automotive engineering.
If all these sensors are calibrated, up to date and properly used... the result variance will be minimal (only due to engine and parts) not the environment as in, pressure, temperature, humidity.
Uncorrected values will follow the air density change.

so for the OP;
cant tie the car down = probably doesn't know how to use the five figure machine. Go somewhere else.

Alright guys I just got back from the Dyno. The owner knew exactly what he was doing not sure why he was asking me if I knew a good tie down spot over the phone. Car is a '06 LS2, only mods are kooks long tubes (I believe they are the 1 7/8"), high flow cats, magnaflow catback and a W4M mail order tune from Jesse Bubb. Car has 97k miles.

Anyways first thing we did a CASE relearn with his Snap-on tool as I had not had that done yet since installing the W4M tune. I had been getting an intermittent P0300 only since installing the W4M tune which went away while running the stock computer for a while. We will see if it comes back. Car has run well.

As far as the RWD setup you guys are right the dyno software knows what's going on, he asked for input of vehicle weight (3850).

Not sure if I am going to have my other stock computer tuned by the LS specialist (he has no dyno btw), numbers seem good as it is running now considering it's nearing 100k miles. Car made 347hp/355tq on 1st pull and 350hp/358tq on the second of two. I must embarrassingly admit that I was running 89 octane at the time of this pull being cheap while commuting.

Here's the pics

Ron is the owner at RS and was very nice and certainly knowledgeable. I told him from what I have seen most Header V's make about 360ish on a dynojet and he said it is certainly making more than that from the comparisons he has seen in cars that have been on dynojets compared to his Mustang dyno which he said it is a bit of heartbreaker for people who are looking for #'s.

For me I just wanted a baseline and AFR's. He went WOT from 2k and he said the AFR looks ok but that it is a little lean up top and that he would tune it about 12.6 on the top end to cool things down.

Thanks for looking any comments or advice is appreciated.

Thanks Jesse you were right on. This is the computer I re-sent you a couple months ago when it had the VATS issue. Been running great. Finally found someone who could do the crank relearn so hopefully that clears up the p0300 that intermittently was popping up.

this is exactly what was explained to me by my tuner (who has an eddy current dynojet), and that people who say "i made xxx on a mustang dyno" just like saying that stuff to feel good about themselves, usually having a god complex that puts the mustang dyno above all else.

You're not saving any $ using lower octane.

I understand that, it was the only option at the pump I was at last and for cruising on the highway this winter it will work, I didn't intend on throwing it on the dyno. /octanediscussion

Your headers glowing red like that makes me think your AFR is too lean.

This! and going cheap on octane will cost big later!
