If we want to bench race, getting the 60ft down in the 1.7 range where it should be it would have ran a high 12.3 low 12.4 I believe.. I ran that pass in I think it was may? 85* and 75% humidity hot and sticky texas heat...

Thanks man! Its fun to hit up the track, make a few passes and visit with like minded car people. It will definately be the fastest 2.7 truck in the country. To this point to my knowledge a guy ran a 12.4x once but was never able to duplicate it. Another guy has ran mulitple 12.5x, he has similar mods to me except he is a super cab 4x4 with radials on all 4 corners.

We're not bench racing. I'm saying, you'd be doing damn good to be in the 11's as that's where the new 10 speed 3.5's end up with intercooler, downpipe, tune and e30-e50 mix in crew cab trim. We're talking about an engine making another 50-70 rwhp so yeah you're doing just fine lol. Hell i sent my buddy a text and said just when i think the N/A 18 5.0 trucks are doing good another ecoboost impresses me.

I'm in southeastern Louisiana btw, so you don't need to tell me about any humidity or heat lol.

I have traction bars and 305/45/18 MT Street-R's for it now, so we'll see how this combo does. I'm going back this Sunday, and then again in November.

That will be a great showcase of the 2.7 potential. I have a SuperCrew and am hoping to break into the 12's myself, but time will tell on that.

You can definitely do 12's, but it'll probably be something like 12.7-12.9 @ 104-106 mph.

I mean, I'd be fine with that. I'm going to try and go back in stock trim one last time this year and improve my time in the colder weather. If I can get it down 2/10ths of a second from where I am currently at, I'll be happy. From there, it will just be one upgrade at a time and testing the outcome at the drag strip.

Well i went back and even without building boost off the line I managed a 12.42 @ 110.8 with a 1.87 60

I fixed the issue where it wouldn't build boost to launch with. I'm going back next weekend and hopefully will cut this time down to a 12.20 with something like a low 1.7 or high 1.6 60 ft.

Dude, I sent you a pm, could you please check your box?
Thanks

I did check it and chose not to respond. Sorry.

Nothin' like a good burn, via internet post, on a Monday morning.

It was about 1800 DA.

Current Mod list too..

Here's the timeslip btw. Left lane. Right lane was a 6th gen camaro ss.

Grats again LTNBOLT!! No more napping on the lights :)

Time for e85. That alone will most likely put you in the 10's. That and the fuel system to support it i guess.

https://cimg2.ibsrv.net/gimg/www.f15...1b926b038.jpeg
Here you go, did another PB since the DA was about 100 ft positive for this pass instead of 1800ish lol.

Right lane, same mods nothing has changed from before.

17 2wd screw tuned on e50 and an intercooler on a mickey thompson et street r

I did a 1.65 60 and a 7.71 1/8 mi but either it decided to pull timing out up top or headwind screwed me but it was only a 12.33 somehow.

Nice 12.28@112.5 mph pass sounds like ^this pass^ could have been a 12.00 pass if all went well?

Very nice!!

That sounds like a typo.... My truck with 600=ft/lbs and a perfect launch never got in the 1.6's, and ran 7.7 multiple times...
What was that about headwind?

https://cimg6.ibsrv.net/gimg/www.f15...f7af242276.jpg
Plenty of ecoboosts doing 1.6 60's man i dunno what to tell ya. Pretty sure you were accelerating faster through the 1/8 than me despite a higher 60.

Weird but cool. Good job. I looked at my slip, and I can't figure it out. Perhaps if our track would let me run in the groove, that would have made the difference. I always laid rubber at the line.

Pretty sure I could have sqeezed a bit more out of her but had to leave the track early.
Only got a few runs in and each one was better than the last. Less than 500 miles on the truck :blush:

What gears?

It's says at the bottom 3.73

EDIT. Sorry Quoted wrong post, no idea what gear.

I got to the rack the last night. 2017 XLT supercrew 4x4 5.0 with Whipple stage 1 with 3.62 pulley, Oz tuned. I have 3.55 gears, 6 speed, and VAS traction bars. stock everything else
Not sure how to upload pics, tried to attch my slip. If it doesnt show, 2.055 60ft, 12.687 at 111https://attachment.outlook.live.net/...animation=true

3.73

There it is. I was wondering how your truck was so damned fast for the limited mod list!

Maybe not in a '16, the 10 speed is pretty slick.

Nice ET and Mph congrats!!!

****, i need to install those 18 turbos on my truck like... yesterday.

Great first post! Welcome to the forum.

Mike

It says in his post 6.5'

Mike

Wicked. List updated! Let me know if I missed anything.

If you are asking me, E50. I have it easy where there's an option for E50 at the gas station nearest to my house, and it actually tests at 50% ethanol.

That is quick for 3.31 gears. Compared to the 3.73, aren't they slower when it comes to acceleration?

In theory yes, however with the ten speed 3.31 gears are more like 3.55 or 3.73 on the old 6 speed auto. A 3.73 would also have to shift more times going down the track, so ultimate acceleration may be higher but over a set distance they would be close.

I'm interested to see if anyone has done any 1/4 mile testing on like for like trucks with the only difference being gear ratios on a 10-speed. Same weather conditions and track.

i know there is tons of debate on this but it would be nice to see a true comparison.

The Ecoboost is faster with 3.15 and 3.31 than it is with 3.55's or 3.73's. There's not enough RPM's to drag out gears like you can on the 5.0. So longer gear ratios work better.

With the 6 speed 3.31 and 3.55 are the fastest ratios. So pretty much yeah.

On the ecoboost the rpms drop right into massive amounts of peak torque, so that's irrelevant.

Are you running a 30" or less tire? If not then that's why lol.

With the same DA ( between 250 and 275) and tune, I ran faster mph and et on my 32.8" 305/45/22 than with my 31.9" 275/55/20 stock wheels/ tires. 12.43@110 on my 32.8's and 12.58@108 on my 31.8's. 5240 lb with me in it with 31.8's, 5200 lb total with 32.8's. 1.79 60' for both. Effectively going from 3.31's to 3.20's because of the bigger tires. Bigger wheel/ tires setup weighs 10 lb per corner more. Averaging multiple runs together from those two days shows the same results. Torque management on that tune could be the reason.

Unless traction is the issue, there is more torque to the wheels with shorter gears, so unless the trans can't shift fast enough or some other factor (other than tire size . torque management as mike mentioned, or loss of boost on shifts) all else being equal, the shorter gears should prevail.

Makes no sense to me, both of those tires sizes keep you in 5th gear before the traps so a larger tire should never be faster here. Especially when it's also a change to a heavier larger wheel to boot.

I can check the logs. Might be that the higher load spooled up the turbos better from down low.

The larger tire also has a larger contact patch, so increased grip could be a factor, especially if it was spinning on some of the gearshifts leading to torque management as mentioned.

he said 1.79 60 on both. No way he's losing 3 tenths in 4wd from shifting spinning the tires.

Have to spin the tires at least a little to get a good 60 foot as launching softer will bog the engine. Although both are 1.79 I could have been going faster through the 60 foot gates because of more traction with the wider tires. (Bog off the line a little, then get into boost hard with grip) and (spin more off the line while in boost but have less ultimate grip) can result in the same 60 foot times at different speeds at the end of the 60 foot. I bet this is the culprit.

Have you looked at the logs? It's more likely that it just pulled timing out on the big end and slowed you down.

2018 has larger turbos. It makes the same power on 17 psi of boost as my turbos do at 19 lbs of boost.

3 things get the gen2 making way more power than the gen1

1.) all 15-17 trucks have same size turbos, but the gen2 3.5 has dual injection so they've redesigned the cylinder heads correspondingly as they no longer need an odd reversion lip to clean the back of the intake valves and thus the headflow is superior
2.) the exhaust manifold is LIGHTYEARS better on the gen2 3.5
3.) harping on dual injection again, it gives you the fuel capacity you need to run the power it's actually capable of making. I'm making that power you see up there at 80-82 lambda, which is about as lean as i'd like to go with the smaller amount of Direct Injection blend i'm running

You think i'm gonna turn down an extra 100 whp for the price of 3.5 mpg? HELL NO. Worth it, don't care lol.

I'm sure the life of the fuel pump being pushed to higher duty cycle will lower how long it lasts. The rest of the components i doubt it.

Is engine high compression? Yes
Does it not have enough direct injection to run 100% on the DI pump? Yes
Relatively high volume of air going through motor? Yes

All this adds up to large gains when switching to ethanol as you're capable of adding 8-10 degrees more timing than 93 octane and i also run another 1 to 1.5 lb of boost over my 93 tune

Truck i saw picked up 200 whp but it was going from 10 psi to 15 psi AND from 93 to ethanol

20 horsepower per degree of ignition timing, seems about right when you're far far under MBT.

I picked up 35 whp from 1 degree of timing on a 1000 whp setup running E98.

I've seen similar with vp's octanium additive. It works. But not as well as they say.

If you're going to the track mix it into half as much fuel to get results you'd want.

Are there any benefits to these products if you're already running e85 or similar products for e85?

No, these products are to improve the octane rating of pump gas. E85 already has a high octane, and the cooling properties are what makes it really special.

That's what I thought. Just double checking.

Another personal best (by far). Left Lane there. Transmission tune and -600 DA did some magic haha.

Nice run and decent 60ft time for a 2wd truck!!!

60 ft was not very good actually. It didn't want to do anything but bounce off the rear tire instead of holding it to the ground when launching.
