1997 powerstroke mods ( advice??)

[ol_Blue97]

when you do it, just make sure you check the fuel pressure when your done. if its too high take it back out. It worked great for my wore out pump

[ratt396]

Hey frank just so I know what should the pressure b before and after and what is dangerous high thanks

Above 50 is ok, 60-65 is preferable. The bb mod may fix fuel pressure issues but it won't fix volume issues. Idling 60psi is not the same as WOT 60psi. Exceeding 70psi and the potential for parts damage steps in.

^^^^ there u go Dan.... and good call on the volume issues with the BB, alot of guys don't understand that.... well i got 65psi?? So i can run stage 2s right???

With all that said im running a BB and upgraded the MOD an called it a FPR shim. Sad part was when i went to do it, i had 10k ohm resistors laying around for the poor mans chip but no BB's, had to buy a pack of 500 for one.

[ratt396]

Lol yep thanks a lot

Sorry to jump on your post Frank. It had been a couple hours and I figured better to tell him what he should know then for him to do the MOD and wonder why he didn't gain anything.

Probly a stupid ? cuz still a stock fuel system but if u were to replace the fuel line from the tank up with like 3/8" or something would that help the bb mod? Just stupid random thoughts in my head. And r there any write ups on a coolant filter for the obs trucks been looking and can't find anything thanks oh and is there any issue with running the small fuel pressure gauge inside the cab? Thanks

[ol_Blue97]

no problem Matt..

dan... if you have a new pump i would just leave it alone.. what most guys do to see the fuel pressure going sown the road is make up a hose with a 100psi guage on it, snake it out from under the back of the hood and zip tie it to your wiper so u can see it going down the road with out it going in the cab! do a few WOT pulls and she how she holds, then BB if needed

Am I gonna cause any damage or premature wear to my augomatic tranny if I put a ts or bully dog 6 position chip on my 1997 ford 7.3?? Ive got a pretty heavy foot so woukd it be okay to run the truck off the highest power setting?

Also is it legal to remove my cat and put in a delete pipe?? Could I make my own cat delete?

From what I've read the cat is designed to oxidize unburned fuel particles. If I remove the cat before I put the chip in, will I get any noticable smoke??

Hey Jordan,

Except for what is in this thread your truck is pretty stock? The chip in general will up the trannies line pressure to try and compensate for added power that the motor is going to be putting out. You'll generally be safe if you at least wait for the truck to shift into 2nd before romping on it and let up on the pedal between shifts. Since you are starting early with looking at a chip I would recommend the one from Tony Wildman (Cary at CT_Performance is a dealer and is faster on the delivery then calling TW in Texas. PM him with questions). IIRC the TW chip is the only one with free reburns right now and you will like that as you can reburn your chip for each upgrade you make on your truck for nothing but shipping.

Removing the Cat.? Depends on your state and local provence. In general the EPA and the DOT both say that removing any emissions equipment from any vehicle is illegal. Here in L.A. County only diesels newer than '98 are smog tested so I removed all my emissions crap as they will never see it. Places like Colorado that test every vehicle every year this wouldn't work per se but if you hollow out your Cat's housing then they would never know without taking it off and looking into it. BTW, here in So. Cal. the test is only "stab the throttle and count the seconds till the smoke clears". Since it is the smog stations opinion to what "smoke clears" means that just furthers the local opinion that the test is a joke. Only a fool would go to be tested on a calm day.

Last question, not particles as in a solid state of matter (ash). The Cat is designed to restrict the exhaust path for the purpose of creating heat. The desired heat is in the 2000* range. The effect of the high temperature is that as the CO2 and CO that are traveling down the pipe will enter this high temp zone and split into their base elements (C+O+O and C+O). As the base elements move on down the chamber and start to cool they start to bond with the other elements that are already present in the pipe from combustion (H, N, O to create H2O, NO, NO2). Since the Oxygen from the CO and CO2 is now mated to the Hydrogen and Nitrogen then the Cat has done its' job of reducing CO and CO2. It was then discovered that NO2(and 3 and 4 this is why it is simply referred to as NOx) are just as dangerous to the environment as CO2 (in fact "Smog" creating compounds are any compounds that are lighter than air and are at least 3 base elements). The issue was with the Cat was getting so hot that it made the NOx. Now they use either Platinum OR Palladium(whichever is cheaper at the moment of manufacture) enriched ceramic honeycomb. The radioactive enrichment of the ceramic material allowed the Cat to not get as hot, flow more "air" through it, and reduce the NOx that was created.
