Dude you’re killing it for the family guys👏👏👏your frustration is seen then those entertainment blips are what makes all your videos awesome. Plus you can learn something. Thank you again 😎

[@ericsmcmahan]

Joe Simpson, it's about time u posted something. Thanks

[@b00st_SS]

Time for a new shop out in the country somewhere! Far enough away people don’t come by for no reason but close enough all your customers still bring their cars out!

[@JoeSimpsonAtTempest]

I’ve been looking for 2 years haha

[@BEANS-O-MATICtransmissions]

​@Joe Simpson yeah, can't wait for you to get TF outta there, im afraid the frustration is burning you out. I can't stand an audience and questions when im frustrated either. Maybe get a portable 6' high fold up wall (3 sided) on wheels to put outside for now. So the lookyloos can't see

[@jesscneal]

Watching you tune something like this makes it even funnier when the other guys say "If you can't tune a car in an hour you suck". 100% those guys blame something and give up. Nice work Joe. Extra mile on this one for sure 👍👍👍

[@phdtuning]

That intro hits me right in the feels

[@Jason-kn3tw]

Love your commitment to making it right - you're the bench mark fur all other tuners

[@CandBLawnCare]

Makes me think about the original shop and all the motorcycles at the place 2 doors down. I’ll never forget the time one guy was showing off and curbed his bike and went right over the bars. Lolol

[@brandonpylant5764]

That fuel pump is louder than the motor lol

[@Turbo4Joe363]

Yeah....that fuel pump howl is ridiculous.

[@jmjautoworks7084]

Nice job man your a stand up guy always going the extra mile!

[@E.T.GARAGE]

Have to l Love this guy the way He analyzes stuff instead of just jumping at it. 👍

[@justinw6448]

Awesome video. I like the videos where you talk about your trouble shooting and how you work through it

[@thomasj.kappjr.929]

Just found your Channel I really enjoy your commitment to making it right, the way break down dyno run. What the problems are and what corrections are being done. Going to watch a few more of your videos but I think you have a new follower keep doing what you do I enjoy it and don't let the visitors stress you out too much put up some signs if you really don't want people to watch

[@robostyle9773]

Thanks for another great video! Good on you for dong your due diligence.

[@KCadbyRacing]

Please keep complaining Joe!!! 😁 "Reality" doesn't bother me and since I do the same type of work (on motorcycles) I 100% understand how frustrating the "distractions" are (and that's before the unwanted spectators start showing up😡)...

[@Robtheman362]

Nice 👍

[@dieseltech1987]

man atleast i aint the only one lol. mine was a frustration boiling pot

[@PothRacing]

Joe, glad I’m not crazy thinking that my car wants to have a ton of fuel at idle on the termx and then look normal after that

[@MrTurbotyla]

Depending on mileage the valve springs on coyotes are sensitive to back pressure. Single 80mm on my coyote and I nosed over early too. I didn’t have enough time to collect data on cam angles.

[@Flitzer514]

Could it be an issue with the crank or cam sensor?

[@bearsstuff]

I wondered the same thing about valve springs. Not uncommon on Gen 1 Coyotes (Gen 2 Coyotes got the BOSS 302 Spring, so marginally better from my understanding). Convince them to measure back pressure and see what it shows on that kit. My guess is too much.

[@finnroen2334]

I have noticed that most americans chose to use single turbos with way to little airflow capacity. I suspect you do not study compressormaps very much.

[@bearsstuff]

@@finnroen2334 No. I don't. I watch KZbin.

[@OneBad-rk3in]

🤣🤣

[@davehaddix947]

Where you located in Maryland joe? I need a couple cars tuned, just wondering how far you are from Morgantown WV?

[@Wings65288]

Lol great episode.

[@whereisamerica7384]

Not every day is a good day. Having issues with a car compounded by 100 looky Lous and jerk bikes chainsawing in your ear all day. But, it still beats clock punchin and working for someone else. Another good video. You aren't complaining. You're being honest. Guys who put videos out where everything goes perfect 1st try and they're all smiles every video are full of 💩.

[@jonathonpollack2325]

Coyote for the win!

[@xxholsteinxx7429]

your logs look SO much smoother than what i am getting. could it just be rfi or are you using less data points so it smooths it out?

[@johnparrotte9352]

Joe, what are your thoughts on the functionality tuning the VCT with the Holley system?

[@Turbo4Joe363]

Maybe set up a serious sprinkler system to hose down the motorcycle dork.... as well as all the gawkers taking cell phone videos.

[@loki91t]

Do you log pre and post intercooler pressure ever? I've seen some pretty sh***y intercooler setups drop boost like crazy. Also LOL at 76mm turbo being described as "little tiny turbo".

[@JoeSimpsonAtTempest]

Yea sometimes. I’ve seen that one go both ways. No pressure loss or a ton of pressure loss. I’ve seen crappy intercoolers kill a ton of power

[@loki91t]

@@JoeSimpsonAtTempest I fixed one car that had a ton of drop across the intercooler by using the post intercooler pressure as the source for the wastegate. I'd hate to see what the turbine shaft speed was, but it held boost that way.

[@finnroen2334]

Have a look at a compressormap or two and remember the horisontal line is like hp/10 and 2.0 PR at the vertical scale is 15 psi boost. This will doble the NA engines airflow.

[@mftsolutions3893]

"One of the most aggravating and annoying things the world has to offer," I feel your pain.

[@GunniGST]

Is your dyno broken? why is the run only 3 seconds? Edit : didn´t see the end of the discussion. Something gone off

[@finnroen2334]

Google tells me that Coyote engine delivers about 460 hp, right? That is about 46 lb/min of airflow. Looking at a turbocharger compressormap, 15 psi boost is at about the 2.0 line at the vertical PR scale. I doubt very much a turbo with only 76 mm inducer can supply 92 lb/min of air at 2.0 PR within the 70% eff. island on the compressormap. ( A S475SX3 can deliver up to about 76 lb/min at 2.0 PR, no links allowed on YT.) I have noticed that it is really common to use a way to little turbocharger airflow capacity when using a singel turbocharger on a modern V8 engine. The reason being cost. Twin turbo is cheaper than a large single turbo with adequate capacity. ;)

[@JoeSimpsonAtTempest]

78mm is the most common street car turbo size on a v8 for the LS platform. For this particular car i never would have chosen a 76 but they picked the kit up used and it’s just what they got. The expensive class legal 76s will make about 1200whp but this is just a standard 76. The argument of twin vs single has been debated for years and it can be argued in both directions being better. 9 times out of 10 it comes down to packaging or simplicity and more racing classes than not ban twin turbos and require a single. For the cars that this engine came out of, twin 62mm is the most common but again its gor packaging purposes that they choose twins as its 2 physically smaller turbos mounted under the car. They seem to make pretty similar power vs this set up. I just tune them i don’t build them or choose the parts

[@finnroen2334]

@@JoeSimpsonAtTempest Yes, that is way I see and the turbochargers compressor maps shows ut that this is to small and not good in anything but a stock cam engine.

[@finnroen2334]

@@JoeSimpsonAtTempest That makes sense. The inducer area of twin 62 is about a single 88 mm turbocharger. This is a correct size for 400 ++ hp NA engine. I know. I have enjoyed your videos for a long time. Smart folks would ask their tuner for advice befor they start the engine build. All tuners have seen lots of mistakes and know what not to do. That is the most importat.

[@johnparrotte9352]

I’m assuming it still has VCT? How well did the Holley controller do?

[@ScottM5.0]

“But..but..it’s cheaper! Who cares about stupid horsepower, anyway? My uncle’s Monte Carlo….”

[@momentummotorsports6137]

Good video as usual, sucked you went threw a bunch of bullshit but seems like its coming around

[@86boostdcapri]

Do you typically not want the car owner there while you tune their car? Just curious..

[@JoeSimpsonAtTempest]

Depends on the car and situation. 99 out of 100 times i prefer the car to be dropped off. I get interrupted 350 times a day which makes the frustration of that even higher when you have somebody there watching you the whole time

[@86boostdcapri]

@@JoeSimpsonAtTempest definitely makes sense. You seem to be in an area where there is alot of traffic/people that can bother you while your trying to work. At any rate, Keep up the good work!

[@JoeSimpsonAtTempest]

@@86boostdcapri I’d say 20+ people showed up while i tuned this car. It makes it impossible to get anything done

[@OneBad-rk3in]

More power is fun until it doesn’t run anymore. Isn’t that the truth. If your not racing for money, there’s no need to push it to the point it’s going to pop, make it run reliable and enjoy it

[@Gillettesgarage]

KZbin star gets mad that fans drive by. Lol 😅

You can see the misfire in the video

[@jimmymccormick142]

Get up with Palm Beach Dyno brother

[@JoeSimpsonAtTempest]

they remote tuned a car on my dyno 2 days ago

[@JoeSimpsonAtTempest]

well....i guess what used to be the palm beach tuner. i think he's out on his own now

[@jimmymccormick142]

Okay brother I just want to give you some good advice cuz I'm a big-time ford fan my brothers actually getting Palm Beach down there to do some work for him right now so I know that they do great work great video man keep up the good work
