Dyno & Bench Racing Forum - can i take this mustang?

so a kid at school wants to race me and thinks he will win for sure, we have met up on the highway several times too much traffic. i really am not sure what the outcome will be i think i can take it for sure but not 100%

his car is 2003 Mustang GT
5speed
shorty headers
or xpipe
75mm throttle body
intake manifold
3.73 gears

my car
1998 Trans Am
A4
SLP Lid
SLP Bellow
Free Ram air
EGR mod
shift kit
3.73 gears
hypertech programmer III
descreened MAF
Flowmaster Catback
throttle body bypass
Ported Throttlebody
(will have Straight pipes from cats back this week)

Its possible this could be a very good race from a dead stop. However if I had to bet I'd say you will beat him easily.

i don't think it should even be a question. The mods on that GT probably can't hold with a bone stock LS1, let alone a bolt-on and geared one.

yeah i didnt think so. thanks for the input, anyone else?

You will win, put some $ on it...

+1, just don't F up the launch and you shouldn't have that big of a problem.

Steve Steve Steve, easy buddy. :judge:

What I was getting at is there is that chance that the GT shows up with some meat in the back and the driver knows what he is doing. Don't think that just because the LS1 makes more power that it is an automatic win. :secret:

Indeed.. I've been surprised by more than one GT. Always got them, but got yanked off the line and had to play catch up. One was just me getting excited and the other was launching at about 3500-4k on drag radials with me babying my street tires.

Take it to the track and find out. It's to stupid to do it on the street. go on a friday night and have the time ticket person cut the ticket in half so you can't see each others time.

Either way, get it on video. I always like watching Mustangs lose. :D

I'm lone in teh Fbod will edge out a win. But "EDGE OUT" is different to everyone.


Why a Descreened MAF? I dont' get that one bit. And why list it as a mod?

BTW - the stang guy wasted $$$, gettin' shorty headers installed. A mod moter is not a pushrod.

The descreened MAF is not a good idea. There are a few mods that might be hurting more than helping. The descreened MAF, Hypertech, and Flowmaster are all garbage.

And it should be a pretty simple win.

With equal drivers, I'd say you'll beat him fairly easily.

The descreened MAF is not a good idea.

I disagree. No problem what-so-ever removing that stupid ass screen.
Why is it not a good idea? It's not like it reduces line pressure in a 4L60E like ported MAF ends.

You will smoke him...make sure its recorded for when you give him the row boat !!

It creates issues with tuning the car, or at least thats what my tuner told me.

But I am going to bow out from debating with you because you have been at this game for much longer than I.

It's all good bro...just conversation...not debating. The real question is, does
removing the screen actually do anything for you? I'm of the mindset that
every little bit helps when you're talking about restricting airflow. but regardless, it's definitely not a make or break mod that's for sure! :)

Steve Steve Steve, easy buddy. :judge:

lol no disrespect bro, but the guy has an exhaust and CAI.

that bumpstick you got probably nets more power than all the mods that guy put on that other GT lol

Theres nothing wrong with a good debate. I quite like it.

I just bowed out because I knew I was heavily out gunned in the LSX experience department.

The reason I said anything negative about a descreened MAF, is because when I had the cam installed, we had a lot of trouble getting it to idle correctly. My tuner at the time said that it was because the MAF had been descreened. I was told that it was a mod that did not gain you anything at all, and only caused problems when trying to tune it.

I understand that it is a slight restriction in air flow, but I was told it also distributed the air to the MAF needles in a more consistant way, making tuning easier.

Sounds to me like your tuner was running out of ideas to point the car not running right at so he threw that out there. I have never seen descreening the MAF cause problems. This is a mod that I have always done on even cars with stock tuned and it has never...ever ever..never never ever caused a problem. If my tuner tells me descreening the MAF will cause the car to not run right I am going to another tuner. Just my $.02

I did go to a different tuner. I wouldn't trust the old tuner to put air in my tires. That guy screwed me pretty good, and is a pretty well known sponsor in my area.

Thread hijacked.

Descreening a MAF does cause issues in SOME cars.

I would NEVER, EVER descreen a maf in a mustang but the 4th gen fbods are different in that respect. In a mustang there is more 'tubing' from the filter to teh MAF, and bends as well. (modulars here). As a result the air doesn't flow smoothly so the MAF can not pick up an 'even' reading of air flow. As a result, there tends to be issues with idle AND tuning. 90% of the A/M CAI issues with mustangs are a direct result with the screen being taken out during install.

In short: It 'can' create a metered airflow problem depending on the car's air way setup.

And Kevin; I wouldn't necessarily go to a different tuner. It really depends on the situation. I may, or may not walk and never go back. :thumb:

thanks for all the input guys. i have never had any issues with the MAF descreening, and ,me being 16 i just do any little thing to make it a tad bit faster because every thing helps.

I'll yank ever screen from every kind of vehicle, just like I did with the Cobra...just like everyone has done with their Cobras...even the N/A Cobras.
It doesn't hurt tuning issue at all. Agree to disagree on this one Pony. :cool:

best thing i ever did was take off the screen AND the maf! and made more powa!
:burn:

For comparison I ran my buddies 01 GT his was a 5 speed with a handheld tuner, CAI, X pipe, catback, and another thing I can't think of. I had my 98 TA and its an auto also when it had just a catback and free mods, I might have had a P&P TB but not positive and I beat him from every race, roll, dead stop, even me completely outta my power band and him banging gears. I always got him by at least one car. So that should be a good comparison.

stewaj11- thanks for the comparison. thats a pretty close one.

16 y/o ..... please dont do this race on the street, i been reading too many stories recently about races ending up in someone getting killed.

Correct...we'll have to agree to disagree. I'm not saying it will always cause a problem and I'm not saying that every car may have a problem. The more bends and 'curves' in the tubing the greater chance of an uneven flow of air. The sensor can't read it correctly if it is not 'even' (so to speak).

I'd love to hear how you got more power by removing the screen....let alone the Maf....unless you just be bein' sarcastic. LOL

^ Speed density tune, a stock maf will hold back a fast 90 setup pretty badly if that is what he had

I was bein' sarcasitc cause he said he removed the sensor. ;)

sarcasm fails me once again on the internet :bang:

hey you are a ford guy do you know much about Fox mustangs?

Only way I see a 2V GT being a threat is if the O.P can't drive.

Well with him being 16 years old I can see this as a possibility.

:lol: It's cool man.

IDk much about foxes. I'm still learning quite a bit about those. My knowledge is mostly in the classics and modulars. But shoot me a pm and if IDK, I'll tell ya.

Get outta here with your logic K. :jest:

Agreed, but what is the possibility a 16 year old is going to scrape together enough cash for some drag radials to use his geared 2v properly?

You should win easily if you can drive...

Depends on if he's done all his chores around the house or not.

And the T/A "owner" is 16 not the Mustang owner. Well I guess the Mustang owner could be too...if that is the case I don't wanna be anywhere close to these two when they race!

lol well off topic, I get to pull the motor BACK out! woohoo am I ever excited. :|

i went with sd tune and picked up about 25rw, but the throttle response and acceleration thoughout the powerband greatly improved. and this is thru a oe ls6 intake and bbk 85mm tb. if i would have went with fast intake, i think it would be over 500rw. but when went with sd tune, vs the maf tune. made 490rw to the old 463rw. tune was calibrated both on dyno and road tune, my mpg also improved and idle quality. car runs like stock under normal acceleration.

You will win, put some $ on it...
What he said..

2v's are weak without OMFG amounts of money in them,I should know..lol.
