Bingo !!

Everyone wants this guy to spend money to go get a compression check and what not, yet no one notices the car was only revved to 6800rpm according to the dyno. Yet it still made 267 ft/lbs. of tq on a Mustang dyno?

To the OP, if its that important to you. Go get another dyno from another shop. The dyno you did in my eyes is whacked. These cars don't make peak hp until 8k rpm.

Dave

This x100.

Thank you to everyone that gave me there insight.. I'm going to take it to another shop that knows there shit.. They embarrassed me.. Lol
Is there such a thing of a dyno mode?? I heard that there's a dyno mode that you put it in?

bradleyland · 03-05-2013, 06:15 PM

"Dyno mode" sounds like someone is pulling your chain man. The whole point of running on a dyno is to see what kind of power you're generating when you're driving. Changing the "mode" specifically for a dyno would be kind of pointless. Why not run that mode all the time?

The shape is definitely concerning, but I think the core problem is that no one has any confidence that the dyno was run by a competent tech. He didn't even run it all the way to redline. For all we know, he didn't even have the pedal on the floor.

I'm with you in some regard though. I think it's a toss up. There could be a problem, but it could be nothing. Before he starts troubleshooting, it's worth getting a decent dyno run in.

M3takesNYC · 03-05-2013, 06:33 PM

I agree, if it were me I would go grab a reputable dynojet. Double check that at the very least your graph looks good and worry about the numbers is less important but should give you perspective. Definetly report back and let us know!

Sad someone can own a dyno machine and be this bad at operating it? wow

Hey now, I just saw this. This was not nice. Nothing I said was out of line and was offering a different opinion. Geez

kerkiraios00 · 03-05-2013, 07:55 PM

I'm def going to get another reading and I will post as soon as i get it done...trying to find the right one!

shivaswrath · 03-05-2013, 10:09 PM

Get ur dyno $ back!

kerkiraios00 · 03-16-2013, 07:15 PM

Ok I just got my car dynoed by a dyno jet this time! I think it went well I still expected a lil more but don't see any issue let me know what you guys think.. Thanks

BPMSport · 03-16-2013, 08:01 PM

Looks perfect.

j2m · 03-16-2013, 08:01 PM

Looks good! is that with your tune?
Good thing you didn't listen to the compression expert

Haha yeah.. seriously!

That's with the Stage I tune.

Keri: If you have the .drf files, send them to me. Would be better to have RPM on the lower axis instead of speed.

Yes it does Mike good thing I took your advice thanks for your help... I didn't get any files Mike just a print out? But your right I shoulda mentioned to him printed it out with the rpms on the lower axis.. The first pull he revved it to 7900 the 2nd to 8100 and the 3rd all the way to 8400 that's why I got the most power! I still don't know y the last pull was lower? Maybe bc it got hot?

That is just plunging in torque. It should be a flat torque line until the last 1k

Its also hard to say your car "feels like its strong" if you have nothing to compare it to. 300 hp is still pretty strong compared to a lot of cars but not when compared to a true 420 hp.

I hope everything is absolutely fine and it was just a total fluke. Although I really don't know how you can explain a funky torque curve SHAPE. Peak numbers or max numbers can be explained by a poorly caliberated dyno but the shape of the curve in my view should not be that deformed if its purely a dyno

Zero disrespect to M3takesNYC, clearly you were trying to help the OP solve his problem.

That being said, it is important for us "arm chair" tuner/mechanics to leave the diagnosing to the experts.

Some of the above comments had the OP believing that his car was effed up and losing compression and that is just not cool. Do not pretend to be an expert if you are not an expert. There are plenty of members with proper experience that will chime in.

LOL... dyno mode, only if you have a civic. Nice to see everything worked out.

TommyLights · 03-16-2013, 08:53 PM

I cant believe our cars make so little power. I was in the 335 world prior, and the car make in the mid 400's for HP and close to 500 for torque. Of course, that is with meth, E85, and a good tune.

I'm going to have to go Vortech supercharger (it's re-branded ESS, but actually is a Vortech) soon.

Hey, some of us "arm chair" guys had him going in the right direction

This thread was more about general troubleshooting than it was strict technical expertise. You never trust a single point of high-level data. You confirm your outcomes, then dig down in to the details. That's just good troubleshooting.

Dave07997S · 03-17-2013, 12:50 AM

Hate to say I told you so..no I don't ...TOLD YOU SO!!

Glad, it all worked out.

However, I hate dynos that show mph not rpm...also it was a STD not SAE which is no big deal as SAE will be a few percent lower normally. Also your best runs it looks like to me to be runs #3 and #4. Which makes sense as the oil is to temp as the rest of the fluids and the car is in the "lets boogie mode".
