Fellas you're killing me here....I don't want this thread to lose it's point.

Hi Built!

Don't sweat it - you got him on power/weight ratio, and shinier paint !

Ooops - sorry Duke. In the doghouse I go

Cheers
Bubba

 

Haha, no problem bubba.

PS. I had a code pull on the truck now. P0172. Rich condition in bank 1. I knew it was bad but didn't know it was bad enough to trip a code. This is pretty annoying to have to deal with this. I mean this wasn't a problem when it was stock and it figures that I go messing with stuff and start having problems. I'm just venting but I'm looking to have a resolution to this next week at the latest now. I'll remeasure the AF1 tomorrow and post the results.

Duke

 

Well it's tomorrow and a day where are the results???????

 

well i guess you guys are lucky in a way,i thought i ordered the 3.25"/excal2...but i didnt state that when i ordered so ended up with 3"..it will work out in the end for you guys..better off IMHO and my 3" doesnt come with a heatshield anyone want to take some measurements for me? come on guys i bleed ford blue too....someones got to have AF1 heatshield there willing to measure for me..

 

Just measure 3 inches down the AF1 and the inside diameter is just below 3".

So it appears I have a 3 inch AF1 and not the 3.25. Which would make sense why the truck is getting more fuel to the air that is making it in.

PS. I sent an email to Neil at TP Monday at 10:30. I'd call but I'm in a conference room with other people till the afternoon.

Duke, did you go to Hitech or DB? Good fellas at both places...

Should be a Dynojet though, and not a Mustang Dyno as originally said, no? Your graphs say 'Dynojet run viewer' and Hitech has a Dynojet, think DB does also. Just pointing it out in case any hadn't noticed as there's a good difference in what a Dynojet and Mustang dyno will read....

Good luck getting it straightened out, I need to get my truck up to one of those two sometime here and see where I'm at for power and a/f....

 

Thanks for the info!

Yeah I weant to HI Tech which currenty has a mustang dyno at their Anoka shop but I don't know if they'll have the same type dyno at their new shop in Elk River which they moved to last weekend.

I just used a dyno jet viewer to view the mustang dyno files.

Duke

 

Interesting, I wasn't aware that they had bought a different dyno, it was a Dynojet 248 last time I was there....

 

Hi Duke,

I just dropped by this thread, and see that you apparently got a 3.0" AF1 instead of the 3.25", and that would, of course, cause the truck to run rich if we have tuned it for a 3.25 - so please do give us a call - Neil and I have discussed this, only because I saw your message here (we don't take any action due to posts her, the customer has to contact us), and obviously this needs correction - and it sounds like you need a 3.25" tube to correct this as the first step, even before you go back to a dyno, etc.

We found that AF1, in one shipment, mis-packaged some tubes - meaning a few 3.25" kits got 3.0" tubes, so it sounds like you might be one of them. We called everyone we thought might have possibly received one a while back, but it's possible that may have been your situation - at any rate, we need to get it corrected for you.

So the bottom line is, let's make sure this gets handled properly, so please give us a call as soon as you can so we can go over this with you and get done whatever needs to be done, OK?

Thanks!

 

Sure thing Mike. I knew that I'd have to call you guys to take care of everything, I was just posting here to remind myself and so everyone could see why I was running rich. I honestly didn't think that I could be this rich on just a tunning fix but rather it had to be something else. Everyone I've read about with your tuning has been near perfect with the exception of a few exceptions.

I'll give a call a little later this afternoon as I have meetings till roughly 3 central time and won't be able to step out of the office.

Thanks,

Jason

 

Hey Duke, what did you use to measure the ID? I'm thinking I should pull my tube off and remeasure.....

-NCSU

 

Hello NCSU,

Based on Neil's suggestion, I pulled the AF1 pipe back off, measured with a tape measure 3 inches in on the manifold side of the pipe, and then used the flexible pipe cleaner type rods that are used in making crafts. I put this across the diameter of the pipe (3 inches back) and then pulled it back out to measure (after I had bent one side to make it flush with the inside wall of the pipe).

PS. I spoke with Anita yesterday and Mike will be giving me a call soon. Unfortunately I caught him in the arduous task of pulling a motor (which I've helped a friend do before and it was a major pain).

Duke

 

Hey Fellas,

I thought I'd provide everyone with another update, just in case anyone is still interested.

I spoke with Mike for roughly 2 hours over the phone. We discussed everything from ethanol to my 1967 GT500E project car. The gentleman has a wealth of information and at times I considered I was in the wrong field of work (consulting) and should possibly switch over to my passion in automotives.

We determined that I received the 3.00" AF1 tube from an unfortunate mix-up on AF1's part. They (AF1) mistakenly packaged *a very small* number of 3.00" tubes in 3.25" kits. Mike and his team were able to catch this in a few of the packaged AF1 kits, but some slipped through.

It was unfortunate but not that big of a deal to me as Mike and his team were extremely helpful, knowledgeable and worked with me to resolve this occurrence.

I'll be receiving a replacement 3.5" tube at the end of this week or the beginning of next week. At that time I will schedule a trip to the dyno again (anyone near Elk River, MN is welcome to come along). I'll be doing a new round of no load data logging and load data logging while running on the dyno.

I'm extremely excited to see what the new dyno numbers will be with the 3.5" intake and Mikes tunes. Not that the 257HP and 329 TRQ (in my 3rd gear pull I posted) wasn't already great, but who doesn't always want more? I had even more HP (262 HP) in my second gear pull but I thought I remember someone posting the HP and TRQ numbers in the 3rd gear pull were the ones to go by in terms of gains.

The entire process has been an awesome learning experience as I learned a lot about Ford motors and the F150 that I did not know.

PS. Did a little math in my head....

Stock Performance on a 3V 5.4L V8 w/ 4WD: [Has been shown on dynos]HP:
Flywheel- 300
RW- 205
(w/ a .317 drivetrain loss that is proven on the 4x4)

TRQ:
Flywheel- 365
RW- 249
(w/ a .317 drivetrain loss that is proven on the 4x4)


Performance after my 91 oct TP tune, 3.00" AF1, and 18 inch SIDO maggie catback exhaust: [given the fuel trims have to be dialed in and the intake will be changed to 3.5" so it'll be exciting to see the number changes]HP:
Flywheel- 377
RW- 257
(w/ a .317 drivetrain loss that is proven on the 4x4)

TRQ:
Flywheel- 483
RW- 329
(w/ a .317 drivetrain loss that is proven on the 4x4)

Gains:HP:
Flywheel- 77
RW- 52

TRQ:
Flywheel- 118
RW- 80

[This is with SAE correction on a correctly calibrated mustang dyno, which if anything reads lower then a dynojet. I'm not saying you'll see the results I did as each truck can vary. Not only that, but the weather in MN was and is pretty cold right now.]


Can't imagine how nice it'll be once those numbers are fine tuned.

Duke

 

Sounds good let me know when you are going then i can see how you datalog and check out how much HP you will be gaining!!!
