SM105K's Ownership/Performance/Maintenance Thread

[SM105K]

That surprised me yet doesn't surprise me.  I mean its like the lifetime fluid BS....they have to know it's really not a lifetime fluid ....like they must know their tune is a little reckless.....to keep you coming back in for service.

LOL.....as we discussed.  Should be interesting with all the new revisions that are getting loaded in tonight on both cars.

Have you got the suspension squared away on the ST?

Blahahahah NO!  Still chatters/clunks.  I am just replacing parts at this rate. I think I have it isolated to the sway bar end links.  I ordered two new ones and all the hardware from Tasca.  Hopefully that will fix that crap.  Hopefully.  That is literally the only gripe I have with that car. Once that noise is gone, I will be so much happier.

I too can't stand odd little noises that are more of an annoyance than a safety issue.  I hope you get that taken care of so you're back to enjoying every second of her.

I had this death rattle in the passenger seat of my Sho. It used to drive me insane. I took the seat out 5 times looking for it. Never found it. I near got to the point of just ordering a friggin seat. I can't stand rattles hopefully you find it buddy.

Finally figured out the damn clunk in the ST.  I needed a new motor mount.  Wow what a difference.  No more sound and less NVH lol.  I am slowly gaining my sanity back lol.  She got an oil change as well.

SHO got a fresh oil change as well.  The Castrol Edge was quite cleaner/clearer than the Mobil One was at 3K miles from what I observed.

She also got a 7 quart out and 7 quart in transmission flush.  It overachieved and I had to actually stop it because it showed zero signs of stopping at 7 quarts.   This is my first flush since the fluid only had 5k miles on it since the new trans.  I was surprised she gave me so much fluid.  Buttoned her up and rechecked everything and she seems to be happy.   

Also my black heat wrap around my PPE DP's is turning white due to the heat they are generating. I found that interesting as well.

I am in the process of purchasing a Magnaflow Resonator so I can delete the rear cat and stock resonator as well.  I will have a exhaust shop fab up a direct bolt in swap.  I will keep all of my stock stuff just in case I need it.   Below is the link to the other site that has pictures.

Got the PPE catted DP's in and they already make a difference for my set up. I heat wrapped them as well.

Fixed a few PICS for ya. Z    BTW feel free to send me a link of any PICS that need fixing! I need the work out!

Nice work my friend and finally no more clunk!!  Winter maintenance is anything below 80?  Haha I'm jealous in winter but glad i don't have your summer heat...geezuz.  7 quarts and you had to stop it?  That new trans is flowing well ...better than normal!  Now that you are the caretaker of the new trans with all your maintenance you shouldn't have much to worry about....defintely nothing fluid related that's for sure!

Those DP'S look Oh So familiar! Lol. Z

I laughed when I realized their journey.  They were built here, sent cross country, just to be sent back here.  LOL.

Couple of things.

I took the ST to CA this weekend.  I have the AJPTurbo Flex Fuel Tune and well......  This is the first time I have actually got to put E85 in it.  Holy crap what a difference.  Ford really did it right with the ST and its ability for the tuners to be able to do things like this.  However they really dropped the ball on the SHO. 

Couple of takeaways.

When I run 87 octane it gets the best mileage by far.  I use 87 on the long drives.  I cruise at 91 mph in AZ, and 81 mph in Ca.  Car gets roughly 25 mpg at that speed and really never see much boost unless I am passing.  Even when I the car sees boost there is no knock.  I have seen as high at 29 mpg at the proper speed limit.  I don't want nor do I have the time to drive the proper speed limit, and either does anyone around me either.

I run 91 octane during the non summer months with a lot of freeway driving 70/30 split with in town driving.  The ST is my daily.  I am averaging just at 24 mpg with my peppy driving.  The best I have netted is 27 mpg with non boost boring driving.  Since the air is colder now I lean towards 91 because it makes great power and for my driving on the freeway it gets the mileage for my boost happy right foot.

I run E54 during the summer.  I don't want to change my driving fun because of knock so she gets the corn during the summer heat.   The mileage suffers, but the performance and my happiness remains.  Best I can scrape with my normal peppy driving is 20 mpg.  Mileage really suffers if I use my right foot heavy.  I have seen it as slow as 18.5 mpg.

I ran a tank of E85 in Ca this past weekend. In CA E85 is readily available, in AZ only E54 is.  Holy crap what a difference.  The car was pretty stupid.  Way noticeable power and a riot to drive.  However, on long stretches of sustained 82 mph, she could only muster 19 mpg.  However...the smiles per gallon were worth it.  E85 was $2.89 a gallon, and 87 was $3.89.  I probably broke even in price point per mpg but to see what the car can do on all fuels is pretty damn cool.  Also I had ZERO cold start issues on E85 in low 30 degree weather as well.  So that is always a plus!

Hats off Brad...once again you killed it.

For the SHO:

The splitter arrived and I will be working with Andrew (802SHO) on a couple of things with it.  Should be fun.  Looking to do a couple of things to the SHO in the upcoming weeks. 

Splitter install on the stock chin spoiler coupled with a paint polish and another ceramic coating.

Man I bet that E85 power left a nice impression on the butt dyno!  Everyone that can safely run E85 ... Usually does.  Would if I could.  But maybe with upgraded fuel pumps I can do a tune revision with Brad for E60.  I can buy a barrel of E100 and mix it half and half with 93 E10.  Make a nice race tune with it.

That is exactly what I am thinking as well, but just with pump E54.  YES! More money to spend!

This was your idea...just like the No2.  Going to have to start charging me for your advise.  Especially if you don't do it but I do.
