2003RedFireVert’s Run-of-the-mill Build

[03' White Snake]

Is that on the end of one of the small hoses that connects to the filler neck ? That has to be what I did….

At the tip of the filler neck itself where it goes into the tank. There is a tiny cheap spring that if it gets damaged, jammed etc. will not allow gas into the tank. People break them all the time dropping the tank. They let the weight of the gas tank hang on it, or shaking the tank too hard to get it to come off, they break this part of the filler neck.

You can either completely remove the tip part with the spring assembly ( but when you fill up you will spill gas) or replace the entire filler neck.

You can see the opening at the bottom where I am talking about in this picture..

I did the Google after I posted and I figured it was this. Im sure I messed it up. I’ll drop the tank later and fix it.

I ordered a new belt and new Motorcraft tensioner so I can my bullet idlers and snub with the KB. Waiting on the dyno tune date….I picked up 11 gallons of E. I can’t wait.

The kit came with a 76in Dayco belt. The setup is stock idlers, no snub, stock lower.

Im going to put on the snub, the three 100mm idlers and the metco tensioner support bracket…I ordered a 78.5in belt. Let’s hope all the measurements I googled are correct.

KB length 3.5 upper, stock idlers, stock lower = 76in
100mm idler = .5in
100mm idler = .5in
100mm idler = .5in
Snub Idler = 1in
New belt length = 78.5in

I run a 79" with 2lb lower, 3" upper, (3) 100mm and (1) 90mm (with the snub bracket). I run a 79.7" with the 3.25" upper. I wonder what the 2lb lower is worth in belt lengths.

Are you running a stock alternator pulley? But yes you should be in the ball park with your new belt it sounds.

I have a J2Fab 185. Pretty sure it’s a stock size pulley or very close.

 

[2003RedfireVert]

The idlers, new tensioner, and belt are on. This is where my tensioner is sitting with the 78.5in belt. I’m guessing this is good? Sitting half way.

My metco bracket is missing the delrin insert so it’s not going on.

Looks good to me.

Still waiting on my dyno tune to be scheduled. It’s drives fine its just little too lean for my liking at WOT on this base tune (12.3-12.6). Hard not to drive this car like I stole it but I’m being patient.

 

[2003RedfireVert]

I’ve been doing a ton of research. I was going back and forth on what to do (MS3, BE/Moates, even having someone remote tune)….my tuner is extremely busy. Being that I get a deal from him (family) I know I won’t make it in anytime soon.

After considerable research and talking with the CoreTuning guys, I purchased BE/Moates quarter horse package. I will be finishing up this tune while I wait and then have my tuner verify everything looks good when I finally get an appt.

I’ve been wanting to get into tuning my own cars for a long time. I’m a data engineer and know how all this stuff works. I have a very good base knowledge (I think). I also purchased LaSota Racing’s tuning book on Ford BE/Moates. I’m excited to get my hands dirty in this tuning stuff finally and I know my tuner will support me and hold my hand as I go along and expand my knowledge.

Should be able to get this all started within a few weeks when everything arrives.

Car runs pretty good just needs WOT fueling tweaks, idle fueling tweaks, and cold start tweaks. I have a great base to work with for my first stab.

I did the same thing re: BE/Moates through core tuning, you’ll love it!

Adam and Ben have been great.

I ordered a DataQ and a DynoCom wideband setup.

Just waiting now…

 

[2003RedfireVert]

This is what I bought. I think tomorrow I’ll be able to get some data logging done.

Lenovo T450s laptop (needed one anyway…)
Quarterhorse
Mongoose cable
BE
EEC Analyzer
Dataey Q box
DynoCom Wideband

It’s nice the cleanestexrr RF install but I’ll clean it up this winter when I have more time and my own garage (we are at my parents house until our new house is done).

This new wideband is reading 11.4-11.7 ish on WOT. The AEM reads 12.2-12.4. The banks could be off but I’m guessing the DynoCom is more accurate. I might get a new sensor for the AEM and see it reads better. They both read similar readings at idle and cruise.

How's that 2.8 feel compared to the stock blower

How's that 2.8 feel compared to the stock blower

Honestly I haven’t really been able to get in it. I’m nervous about the timing I see in the tune. I thought it was running lean until today when I saw how the new wideband was reporting proper AFR at WOT. I’m going to datalog a few runs tomorrow I hope and depending on what I see I’ll let her rip. It hits 17-18psi at 2500-3000. My stocker only hit 14-15.

Stay tuned….

Yes sir. I'm sitting on a 2.9, fuel system, ect. Just waiting to pull the trigger, my car is super balanced how it sits now, so I'm contemplating on what to do

FWIW, when I was talking to the guys at Megasquirt they said it wasn't uncommon for these cars to be a point off bank to bank at WOT. I still see about half a point split between the banks on my set up. I'm not sure if it's the fuel system set up or what. But at idle and part throttle the numbers are damn near identical.

Throw the blower on. My car was well balanced on the stock blower too. But the Whipple is so much fun.

That is interesting. They are a point off almost to the decimal. Driver side being leaner.

Timing is looking proper after some logs today. Nothing over 15 degrees.

I’m going through an touching up the MAF curve in Open Loop. This will take me a while but it’s fun and I’m learning a lot. Car pulls hard!

I have a dyno tune session for E85 schedule for Nov 17 (4 days before our son is due to be born). Should he come sooner I will reschedule. The 93 tune I got pretty dialed in. I’m not confident in doing the E85 tune especially why it comes to timing. The fuel part is easy.

I’ll post numbers for 93 and E85. I’m expecting 600ish on pump and maybe 670ish on E.

No other updates or upgrades. We moved into our new house and about to have another baby so funds will be limited for the Cobra.
