I'm curious if it's possible to have a California smog legal S197 Gen 1 coyote car that is 10 second capable. I have a roush phase 1 supercharger on my 2014 coyote, and the best I have been able to do is 12.7 at 114.9mph. This run was on street tires with a 2.2 60ft time, I have slicks but I did not get a chance to run them due to COVID shut downs. The car is daily driven and I don't want to break anything and I want to keep it smog legal in California. I am jealous of all you other people that get to do cool stuff and I'm stuck with having to have an EO number for more power. I know the car should be capable of 11s, not sure I am but I would eventually like to run 10 seconds in this car. I know it would be easier with an S550 but it's out of my budget and I bought this car new so that means something. Every car I see running 10s is not smog legal in some way or another in California so I am wondering is it possible, with the roush tune I have 499whp and I don't think that is enough to get the car into the 10s, I do not want to strip the car down but am wondering if there are any smog legal ways for more than roush offers or will gears help, ect.

You need a tire, and a driver. You have more than enough power. I ran an 11.2 with my 2011 GT. No power adder.

You certainly can. You need the proper tires, proper launching technique, and eliminate any extra weight. With a power adder, even a phase 1, you should be solidly in the 10’s.

You didn’t mention your transmission. If it’s an M6, then you need to learn how/when to shift effectively. If it’s an automatic, you could even replace the torque converter with a performance model that has a higher stall-speed.

Work with a good tuner (AED comes to mind), and get some seat time.

Is that with a stick or auto?

It is an M6, I just replaced the clutch with a Spec stage 2, not for times but because the hydraulic throw out bearing failed. As far as tune it is the Roush tune, Most tuners will not ship to California due to EPA crack downs. My concern was if the Roush tune is possible to get the car in the 10s because that is what is California smog legal. I am going to run slicks and front runners as well as get a decent launch I haven't been able to launch at anything above idle and when I turned off stability control it does go sideways going into third gear on street tires.

In theory you ought to be able to get down to a 1.6x 60' time and that will knock about a second off of your ET.

I'd like to know why you are only trapping 115 with a blower, when I trapped 112 stock with my 14.
Horrible DA (weather) and/or altitude? Low octane gas? For reference, with Roush Phs 1 kit, Phs 3 pulley, and VMP 93 tune (otherwise bone stock for engine power mods), I trapped 125.

So it's about 1.2-1.5 X lower 60' to figure out lower ET. So you ET'd 12.7, but want 10.9. That's 12.7-10.9 or 1.8/1.5 = 1.2................ 2.2-1.2 = a 1.0 60' (theoretically) to get a 10.9 run. Obviously this is not all set in stone, but you are going to need a hell of a suspension and be a darn good driver to run 10.9 @ 115. I think the S550 A10's run 11.9's/12.1's @ right around 117/119, so that is about what you should probably be running minimum right now I'd guess with even the crappy Roush tune.

The other option is using a different tune except for smog. Do they really drive around and do spot checks on which tune you have? I could see spot checks for visual items, but the tune will really wake up that car if you can swing it (also the phs 3 pulley, will anyone really know, gets you a little more boost)

Yep, my thoughts exactly. Nothing wrong with multiple tunes.

like someone mentioned before, get a track tune have it tuned for e85 would be my suggestion, slicks and seat time next.

As a number of posters have noted it is possible. I'm running an edelbrock Eforce stage 3 with kooks long tubes and green cats in a 2013 GT with M/T Et streets 275/60/15 and it is an auto. My best thus far is 11.09 at 129.46. I have no control over DA's I'm in western PA so elevation at the two tracks I run is 1700'above sea level. I removed the sway bar have a braille battery and removed the back seat. I just purchased a set of Hoosier quick time pros 11.5/26/15. They are supposed to be "stickier" and a little lighter. The first thing is to get a slick. I would expect to see your 60' drop to 1.8 - 1.9 right away. Have you at least added lower control arms and relocation brackets to set the control arms to a downward angle towards the axle. FYI, I was able to run 12.4 112 mph with Ford pro cal tune, a p245/40/18 drag radial, short tube headers, and an aluminum drive shaft.
Tires will get you started. Other suspension mods will help. Not sure a different tune would do much. If you go to E85 you are probably going to need injectors and a dual pump fuel system as you probably don't have enough capacity even with a BAP to flow E85. That has been my stumbling block I'm looking at a 4K with Fuel system (~1500) injectors (1000) Lund Tune (800) Remote tuning device (600) and two hours of dyno time (300). Every day I think about going to E85. I have resources to do it but it brings its own set of problems.

I thought 115mph was low for the blower, stock the best the car would trap is 110. I was expecting to trap around 118 to 120 and the time would depend on how well I can drive it. I know it's 11 second capable, I just don't know if it is 10 second capable with the roush tune. I have thought of getting a different tune but not sure how that would work with California's laws. Roush encrypts their tune so it's not as simple as saving it and then re-writing when you need to pass. I was thinking the stability control may have something to do with low trap speeds, I haven't been able to turn it off because the car goes sideways in 3rd and I had to really back off. The main reasons I went with the roush kit was safe for a stock drive train but I see everyone getting away with more. I am thinking I would do oil pump gears before going for more. I can't get 93 octane in California only 91 so that may have something to do with it, I was also thinking that the torque management may have something to do with it. When the car was stock I had drag radials and I would trap 108, and it was in line with every other S197 Mustang at Fontana on drag radials. Those tires got old so I cannot use them anymore but I finally got slicks and when the tracks open up and I get a chance I'll run the car with slicks and stability control off. I have thought of the phase 3 kit but don't know how well the car will handle it, I have heard once you go to 600whp you need to upgrade the rods and I'm not sure about the MT82 transmission. Anyway I was wondering if it is possible in the California smog legal configuration, it may not be, per California the tune makes it not legal although you may get away with it. I may try it in the future I want to get the smog first just to see how they act just to the blower. Smog in California is a pain in the ass which is why I used to only mod cars that were pre 15 but now the few that aren't all rusted out are too expensive.

I have lower control arms the non adjustable type, I am going to run it with a tire and a front runner. What I was wondering is to stay California smog legal is it possible to run a 10 second time. I know the tire will make it faster and possibly dip into the 11s but I don't see it getting to 10s with it's current trap speed. I would love to do all that cool stuff you guys in other states do like long tube headers and full exhaust I'm sure that alone would get me were I want to go, or the stage 3 roush would but those are not legal. I don't have easy access to E85 where I live and yes I would have to do the whole fuel system and ironically that is also not smog legal. Our laws plain suck and I may just look for a way around once I get the car down with the slicks. I probably would do oil pump gears before doing anything else. Just out of curiosity how much power are you putting down and how many miles are on your car.
