    Stock fuel system e85 tuning

    Alright guys Explorer ST, I get asked this a lot. “I want to run ethanol, but I do not want to mix fuels and I’m not sure I want to buy the Xreme DI pump yet, is that my only options?” I typically try to get people into either e50 or buying the HPFP because that is what it takes if you want to...

    Downpipes

    Yes, tuning wise I'm seeing good gains with downpipes. The st seems to be picking up 3-4 lbm/ min of air flow, which is consistent with 20-30hp. Of course you'll only see the gains of you are pushing the limits of the turbos. Even if you are not pushing them to the max it will still help...

    Turbo Upgrade! Market Research

    Like I said it comes down to advertising and perception/target market. If you look at ford and Lincolns own website it says aluminum as the block material which is partly true I guess. Sent from my SM-N975U using Tapatalk

    Here is the st motor, the CGI upper block is visible. This is true on all Nano applications, all Nanos have the cgi upper block. Sent from my SM-N975U using Tapatalk

    Turbo Upgrade! Market Research

    That's incorrect it is still a compacted graphite iron upper. It comes down to advertising Ford advertises the truck motors as having the iron block because that matters to people cuz they want the perception to be that it is a strong motor and really only half of the block the upper half is...

    Turbo Upgrade! Market Research

    The 3.0 liter has the compacted graphite iron upper block which is very robust. The weakest link on a 2.7 seems to be the pin bore on the piston. I've been told the 3.0 liter is a substantially better piston so I don't know what the failure mode is going to be yet. I'm predicting connecting...

    Turbo Upgrade! Market Research

    The 3.0>3.5 in my opinion. We were able to squeeze 600 horsepower out of a 2.7 l do 550 to 580 pretty regularly. I think 650 on an un opened motor is realistic but it also probably won't last forever at that power level. Kind of the game you play when you are modifying though. Sent from my...

    Turbo Upgrade! Market Research

    Here are some initial data from the pure turbos. We are currently at the limits of the fuel system just barely leaning the new turbos. These things are going to move out once we get more fuel system! Trap speed has consistently been 118-119. Which would put this in the 550-600 hp range. Sent...

    SCT BDX vs X4 ?

    Go with the hp tuners RTD or MPVI2 (both require a laptop). Sct support is very lack luster these days. And if you are looking for a custom tune I wouldn't go with the n gauge because the data logging on the ngauge isn't very good. Sent from my SM-N975U using Tapatalk

    I would see if you can get some revisions from them that's of the mark for stock and e50. Sent from my SM-N975U using Tapatalk

    ST Tune

    Did you turn advance track of? Is the spike in g force the 1-2 and 2-3 shift? Your 60' is definitely the reason for the bad time. Should be doing 1.8-1.9 no problem. Sent from my SM-N975U using Tapatalk

    Can you dual boot your mac? It really doesn't take much of a computer to run hp tuners lots of guys buy cheap windows tablets and leave them in the car. Sent from my SM-N975U using Tapatalk

    Best tune for 2020 Ford Explorer ST

    Yes it is 4 credits, since you can use the RTD on multiple cars the way they license each car is by credits. In order to register your car with you're device it costs four credits. If you want to do another vehicle with the same device all you do is buy more credits which can be purchased at any...
