For the time being...has your car ever been tuned on a Dyno?

not yet

[SmackedInATL]

not yet

That's your downfall. I would have never done that pulley without a dyno tune.

[SmackedInATL]

Actually it is the same for twin screws too. It's not just the heat from the stock blower. SVT neglected to make a coolant exit for the driver’s side head. There is also a tight piston to wall clearance and the lack of bronze valve guides in our heads makes them even more susceptible. So, too many back to back high speed runs (140mph+) could cause the car to overheat or damage the heads or pistons. The problem could also lead to the common head tick issue.

If you don't at least have a wideband or a engine temp gauge I wouldn't even consider it

What about a head cooling mod?

Edit: Plus, I'm pretty certain my car has the new heads in it too...its late numbered car. I have to verify that though...

dyno tune just for a pulley?

you do realize there is no such thing as a "pulley diameter" sensor? Its based off a map table. So he can run a bigger or smaller pulley and the map will correlate it regardless.

The CAI is another story. That will adjust LTFTs and lean out WOT. The pulley however, will not.

LOL! You do you bro!

Also where you on Barrett Friday Night with 2 other mustang's? One Gray Foxbody and the other was 96-98ish maroon both supercharged?

this may be the one in the AT&T parking lot by barnes and noble. I stopped there the other day to get my phone looked over and saw a white termi, looked nice non the less...

Yeah this Cobra was white also but I never got to talk to him b/c he left the other two stangs but they told he me he just bought it and wanted to see what it could do. I just missed that race.

I guess no one knows the phrase "you do you". Basically, it means, if whatever the guy who commented on not getting dyno tuned after a pulley isn't necessary, then he can believe that and go about his business. Me, on the other hand, would never do a pulley swap without a dyno tune. My .

Anyways, sorry for the "ebonics". Yes, I was on Barrett with the 2 stangs you mentioned. If you want to have some fun this weekend just let me know and I'll make my way out there.

Im not knocking not tuning it after a pulley since the same stock tune that was done to it off the factory floor is just as likely to be flawed. I notice when i drop pulleys i have to drop the timing on my map a couple of degrees on the new cells i hit but it isnt any more dangerous than what GM gave me.

I tune my car anytime i go below 35 mpg to work.(once a month or 2) My performance cells under WOT dont get touched unless i do some sort of bolt on.

The head cooling mod will help with the coolent flow issue, but does nothing to help the piston to wall clearance. After romping through the gears, the car will get heat soaked. Hitting 5th gear at WOT puts an excessive load on the engine. This extra load causes heat, which cause pistons to expand... you do the math.

The revised heads with the coolent flow issue didn't come out untill Jan 05. No Cobra came from the factory with them. Some of the late run 04's did have 9 spark plug threads. That is the only difference.

It's your car so run it how you want, but I would stay away from WOT past 4th

Im not a ford guy so excuse my ignorance.

We have/had the same problem with our cars. However we have an intercooler built in to our intake manifold to drop the air charge temp but the system only held 2 quarts total. We generally take the cobra intercooler and attach it to our cars. I've also noticed it is very small. Why not upgrade the intercooler with one from CX racing. It holds a gallon and can probably keep your IAT2s down like they did mine. I saw a 40 degree drop.

The other option of course.... head work or methanol.

oh yea, and the ford guys manufactured us a killer chiller too

Dude.. are you serious. You need to tune your car anytime you add air or fuel to the mix.

[rrutter81]

no that is exactly what im saying.

the MAP cells wont change because they are predictive calculations of the pressure inside of your manifold. Infact you would probably have to hit 50 PSI before you got off the chart.

The map sensor takes your RPM and the PRESSURE and calculates the fuel to add to it. The only time you are tuning it, is when your sensor is saying it is at a certain pressure when it really isnt. (eg porting and polishing). Even then your o2 sensor compensates during regular driving with LTFT and STFTs. After WOT it doesnt know what to think short of what the MAP says and THAT is what needs to be tuned.

All in all, if all you do is change a pulley, you do NOT NEED a tune. The airmass calculations are done unless you mucked with how much flow your getting....eg new intake etc.

We have an IC under the blower in our intake manifold too. We also have an Aftercooler (heat exchanger). An after market Heat Exchanger is a very common mod, but an aftermarket IC doesn't do much (not worth the money). There are many other cheapers cooling mods that will work great. Just for exmple, new T-stat and having your fans come on earlier. Ford also has a killer chiller for us too. I have heard great things about it

Adding boost will change the MAF counts. When I ported my blower and had the same pulley, I DIDN't need a tune. I re-tuned it when I upgraded the injectors. When you go from 8PSI to 13-14PSI, you need a tune. I understand the tune is only for WOT purposes. The o2's controll averything at regular driving

[SmackedInATL]

Good info you putting out here SicStang...

I'm gonna hit you up tonight, I got some new info about my ride...

no it doesnt, stop spreading the fail. Ill hook my software up to your stang and show you.

All it does is put you in a different cell you normally wouldnt be in under a smaller pulley. EG: 71 kPa at 1200 RPM under WOT you will just be pushed over to the 78+ kPa cell at WOT but it would still be there without the tune because it was already configured for you.

The only time you need to tune those cells is just to tweak them in to your settings.

As far as the MAF goes, it will go unchanged. NO CHANGE AT ALL. IT SENSES THE AIR coming through. It doesnt change with a pulley. When you changed the pulley all your doing is getting to a higher cell faster.

Also: on a side note... of course you wouldnt need a tune for a ported+polished SC. It doesnt do anything that radical. It wont change your AFR because THE MAP didnt change.

Tell you what. I have a 2.8 pulley in my trunk right now. Ill give you logs of how different my MAF/MAP is beforeand after i drop the pulley to that size.

Guaranteed it will not change, just like when i pullied it from a 3.4 to a 3.0. the new cells i hit will need to be tweaked a little, but not what was already configured+tuned. Hell even my VE table isnt off +/- 1%. Thats unheard of for tuning. (generally 3% difference during different days alone)

WTF are you talking about? AT&T? I do not go in any AT&T parking lots. I do not even know where Barnes and Noble is on Barrett?
