My run on dyno today

[yryr999]

Hello today I decide to go the dyno ..
I made two run here is the result ..
the car have K&N CAI with Autolite xp104 and 180* thermostat rear cats delete flowmaster muffler .. and a tune ..

waiting for your comment , opinion and advice if don't like the result ..

[Mr. Man]

Is this a Marauder or a CV? Numbers seem low for a MM with mods. I thought a stock MM was putting 240ish rwhp down.

[clmrt]

What octane, temp / humidity, etc?

Which tune? Custom from dyno guy?

[yryr999]

its a marauder :bigcry:
I don't know what the problem ... :mad::mad:
the car run fine everything is good ...

[yryr999]

What octane, temp / humidity, etc?

Which tune? Custom from dyno guy?

91 octane ,,the temp around 75F ,, humidity i don't know ..

Me too?....

[slickster]

If it's a custom dyno tune that might be the problem. Or a tune up issue

[BODYMAN]

A/F looks way of! If Iam seeing rt it said 13.9 or something?? should be around 11.5 Thats the 1st problem You wanna get fixed.

[breeze]

Yea something is up. I did better numbers stock.

[slickster]

I hope you can get a refund from the guy who did the tune and get a vendor tune

[yryr999]

May I know how you know the tune is the problem .. ??

[clmrt]

A/F I guess.

[yryr999]

A/F I guess.

maybe ... does the TQ have a connection with this ..?? or weak transmission
or what ..

The Afr on a n/a car should be 12.8- 13.2 they need to add more fuel.

[Odinson]

Don't panic dyno could be screwed up. Apparently it happens. If looking for a local tuner, mustang shops are the best bet.

Oh and overdrive needs to be off. Won't get an accurate read otherwise. If he didn't ask where the button was probably didn't shut it off.

Stock numbers on a humming bone stock engine/tune are 230-240rwhp and 270-290rwtq Just did mine for the first time few months ago.

the overdrive was off and the run start after 88mph so the trans won't shift to 2nd gear and this roll was in 3rd gear ..

[Krytin]

I have similar mods - JLT air filter/intake, 180 degree stat but I use the xp103 plugs - one step colder heat range.

When I had my last dyno tune my A/F ratio ran a steady 12.0 through the pull and gave 269 RWHP & 294 F/P RWTQ.

[DOOM]

What tune was on the car when you had it on the dyno???

Bone stock is 230-240rwhp and 245-255tq. TQ that high on a bone stock car is because of an improper reading, shift spike or 2nd gear run.

That's what I was thinking the problem was as well, another reason why the A/F could be off.

Just looked at my stock dyno did 243hp 259tq up to 5500 rpms.

Your tuner in Saudi Arabia needs to add fuel. AFR, Air Fuel Ratio, is 13.99 pounds of air for every pound of fuel. If you add more fuel, that will bring the afr down. You want it at about 12.8 to 13 pounds of air for a pound of fuel.

I wrote RICH and I meant LEAN. It's too lean and needs to be more rich.

Ck his location! He may not have a ton of options for performance shops. As another member stated 12.0-12.8 IMO is just about perfect for A/F on a N/A car.

I agree with you...and gasoline tried to decrease to 12.8 ..


Good luck my friend :)

LOL. I didn't! Doh!

But.. on second thought isn't Ford everywhere and Isn't the ME full of motorheads? There has to be a modular ford shop somewhere. I mean Fords gunna have a 200mph street car out this year. Screw the Germans.

[yryr999]

What tune was on the car when you had it on the dyno??? My tune from Lidio .. :confused:

I send him the photo and he didn't mention adding the fuel or something else

[yryr999]

bro I send him the dyno photo and he never say its need more fuel ..
you too bro ..:D

[yryr999]

I try both tunes .. Lidio and Dennis ..
Dennis tune added 2 wrhp ..
I upload the dyno photo for Dennis tune ..

[ctrlraven]

The AFR on that is even worse!

91 octane <---Why? ,,the temp around 75F ,, humidity i don't know ..

Why you run 91 octane......

[yryr999]

Why you run 91 octane......
we don't have 93 octane just 87&91 octane :(

[CBT]

we don't have 93 octane just 87&91 octane :(

You can't get 93 octane in Saudi Arabia? That's like going to a bar that doesn't serve whisk....nevermind, that analogy wouldn't make any sense to you.

[SC Cheesehead]

we don't have 93 octane just 87&91 octane :(


Interesting!

I discovered they've got 97 octane in Qatar when I visited there last year, would have figured you'd have the same, given the close proximity of SA and Qatar.

[yryr999]

indeed .. all other countries have 93 .. except SA :bigcry::bigcry::bigcry::bigcr y::bigcry: ..

[Talal DTR MM]

indeed .. all other countries have 93 .. except SA :bigcry::bigcry::bigcry::bigcr y::bigcry: ..

yryr999:

what we have in SA is 91 & 95 octane. I'm using 95 which is
recommended from all tuners in SA.

Just curious, how much is it a gallon?:confused:

[Talal DTR MM]

Just curious, how much is it a gallon?:confused:

For 91: 1 Liter = 12 cents.
For 95: 1 Liter = 16 cents.

1L = 0.264 gallon

[lji372]

that's BULL:mad2:

i want almost free gas :D

[Mr. Man]

Are you running Lidio's 91 octane tune? You probably are but it could be a silly mistake. If you can get 95 octane I would see if Lidio can tweak your tune to run that. You could run a bit more timing.

[dohc324ci]

What kind of dyno is it? Seems about right for a stock MM.
