Good stuff man. You're one of the only people on KZbin that really thoroughly explains what you're doing and why.

[@SortaProfessional89]

Amen to that.

[@FishFind3000]

He’s the only one that actually knows that’s going on. He’s not just bolting shit on and having someone else fix it.

[@Rick-bu7qd]

Exactly

[@rickbullock4331]

I think you know what you’re talking about Jeremy, way above my pay grade for sure. The technical info is way too complicated for me but I’m sure there are lots of younger people who will understand the words of wisdom you give them. I’m 73 so this stuff is way out of my league but I do like to see the numbers when you run the vehicles on the dyno. Nice work!👍👍

[@KnoxGTX]

You know you're in a good shop when you see Mazaks everywhere! Very cool!!!

[@comporangesvt]

4.5" Pro-M univer, and 4.5" alluminized exhaust piping with couplers

[@micahshepherd8112]

Definitely enjoyed this one. I want to learn to tune one day, so you're testing and explaining was very intriguing. Keep them coming

[@Dfwrich]

need a fasterproms lint roller

Curious to see what's to gain from the stock 90mm LS2 throttlebody on this TVS2300 (jackshaft style) 2005 Corvette to a NW 103mm. Car last made 618/639 to the wheels @ 14psi.

[@user-qu6yv8el3e]

New video after being down? Good compromise if you ask me

[@The-Life-Of-Brannon]

Idea for Cat-Back exhaust Magnaflow performance muffler that would sound good

[@Yophillips3272]

That throttle body factory reminds me of meet the parents when the guy was showing off the altar and said it only took me 70 man hours, which isn't bad considering I carved by hand from one piece of wood.

[@boosted0079]

I have to ask, what map sensor are you using, and where is it routed to? I'm just wondering how you're getting the vacuum readings in the intake between the TB and blower? I'm hoping to get a reply lol

[@MajorPerformance101]

How come their aren't very many people utilizing an interchiller A/C setup?

[@pauljohnson7382]

More huff- More Puff. 👊 Function over fashion!

[@Dukes3677]

Awesome to see the machining stuff, as a machinist it's awesome! Lol

[@Turbogto_guy]

I always enjoy the shit out of your videos. One day, when you have a turbo vehicle on the Dyno, I’d like to know if going from a stock throttle body to a bigger one would make any difference. My guess would be zero difference on a turbo car.

[@jamesduffy9756]

Honestly. Probably nothing.. it would probably make the throttle laggy or choppy depending on the tune but for power. Nahh

[@jamesduffy9756]

Unless the throttle body you have on it is so restrictive then it wouldn't have anything but to benefit from it some.. that's boutt it

[@Turbogto_guy]

I’ve got a 92mm Tb on my ls1 turbo gto. Throttle is way too sensitive. I’m thinking on going back to stock. My intercooler piping is 2.5” which is smaller than the stock throttle body bore. So in my mind, I see no loss.

[@brucefrye8799]

I'm learning so much from you and the real world examples

[@chestermcgillicuddy4368]

"junkie" and adds the arm vein slap! Classic!

[@jimmypatriot5203]

Hell yeah man. Love that you show the CNC work. Been doin CNC for 7 years now. It's very interesting how you go from a chunk of aluminium to a functioning motor piece. Love the channel bud! 👍👍

[@rickyortiz5052]

When are you coming to Naples again??

[@schit4brainz]

Tell Leroy to pull his pants up and put on a under-tray and diffuser. So we can see him run a low 7. What's not bumpers, fenders, hood, doors, and quarter panels is still a skeleton car. He should set the record that really shouldn't be beaten simply because of physics.

[@nataliedeyton6829]

I really like the more in-depth video 👍

[@matthewsmyk9091]

With great beard comes great responsibility - and boost......(buy the pulley....!!)

[@aklip]

Papa Jerm bringing the boost.

[@Genesis385]

Do a black widow neighbor hater muffler for the cutout! 😃😃

[@bad4health]

Wasn’t he suppose to b plugged into the rear port for the map sensor and that KPA reading was suppose to be boost aka over 105kpa

[@icardenas3909]

I love your videos! They are getting better each time.

[@n5yiz]

Wife must have put Jeremy in the doghouse....

[@troy_rx7939]

G'day Jeremy. Nice work on the porkipotomas....this guy down in Aus makes awesome cutout kits and even extreme duty ones to handle the most aggressive antilag/2step. If his gear can handle rotary 2step and over 1000kw stuff it should walk all over what you will throw at it. Some links to his site and fb post showing his super duty cutout.. www.activeexhaustsystems.com.au facebook.com/459871950728061/posts/1792315620817014/ Just for the when your electric one fails.. :p Oh And i have nothing to do with this guy i just like his work.

[@michaelmorell7451]

Jeremy...What do think about those Varex mufflers with built in cutout?. With the cutout closed, it's quite than other performance mufflers. They also sell an upgrade to adjust the blades to whatever point you want. They come in so many sizes.

[@davidwindsor2866]

Great you got your wife. Wanting to make some power. HP junkie. Burning the late night candle. Dedication. Buddy. 😉😴😜👍👍👌

[@robarell3758]

I'm curious. How many cfm are your heads flowing? Any head work done or any in the future? Hmmmmm...Bigger throttle body more air through the heads, more lift and duration perhaps....lol!

[@jasonbeaulieu4979]

Just ordered a NW 102mm Boosted TB for Magnuson TVS2300 vette, really hoping I don't have problems with it.

[@stevenquere8243]

Screws on top of the supercharger, really? Your brand new LT4 supercharger will turn into the piece of junk blower that somehow makes decent power even with shredded roders; all because of one tiny little screw.

[@conwayfiddy4908]

Hey, I have that same shitty cheap caliper, $36 on Amazon. Compared it with a friends Starret and it was pretty much the same, sometimes off by one thousandth. I was impressed.

[@IDK_Mr.M]

Next car tune it running 60% of max HP. then when she asks for more power just change the tune.

[@tucobenedictopacificojuanm5570]

It would appear that your wife, in addition to being a "power junkie," is also a "shopping junkie," judging by the bag in the back seat!

[@KCadbyRacing]

Even though my love for Making Power is on Motorcycles I love watching your videos👍👍 I have always been curious about what and why stuff works and your videos are awesome!!! 😎 It's SO true about wanting/needing to do comparative dyno runs as close together as possible, especially here in FL where conditions (like humidity) can change quickly...

[@maxthemadtuner]

Can you elaborate how you check on the intake restriction using vcm scanner?

[@Ernan302]

Volant makes 4" CAI Part # 155546 and 15554 for 15-18 scalade and Denali. I have video that shows engine bay on my 16 Denali

[@emiliano29171316]

Install an Lsa supercharger in the miata

[@derakbell8143]

Rear mount turbo would be kool to and keep some weight off the front

[@willowwonderbull7100]

have you checked out steve meade's escalade its making like 900+ you guys with the stealthy fast escalades killing the game

[@curtisfarr9411]

You should call out and race Jeff from HIGH PSI TV in his blown tahoe

[@vortecturbo]

brother hey it would be best to run the hottest water from the blower to the heat exchanger. Then to the expansion tank would stay cooler much longer.

[@retsaoter]

"It isn't rice if it has a purpose. Preventing a bumper fire isn't a believable purpose, but preventing ANOTHER bumper fire is." - Dave Coleman, former Street Compact Car Magazine editor, about adding a heat shield to his bumper after a fire at the race track.

[@choochoothelilsavage9573]

Real funny jeremy.. Thought you made or sold pulleys for any GM on the planet.

[@WarriorOfEden3033]

So would you say if you are increasing a DBW throttle body by any amount a tune is necessary

[@jamesduffy9756]

Also I have a 09 Hyundai Genesis sedan 4.6 V8 180,000 highway miles. , I've been looking for more power without going supercharger or turbo, would it be worth it to get my car tuned? And if so would I have to go with a different ECU to get it tuned ? Or are there some things I can do to get more power out of the car without a aftermarket ecu? I'm just broke af and between jobs right now so I'm looking for budget power right now untill I start taking in some cash and be able to buy real upgrades

[@Fasterproms1]

Don’t ever put yourself in a pinch over car stuff it’s a bad move. When you have the $$ you get what you pay for most of the time. Depends on the tuner. I typically recommend my customers do most of the bolt ons before having the car tuned and everyone’s happy in the end.

[@BustedWalletGarage]

If I purchase a shirt does it come with all the dog hair like on yours ?

[@fernandobanuelos4965]

Why won't you go with a flow master super 40 and open up that exhaust

[@sunnyray7819]

If you run a little lean does it keep the engine cooler say at idle on a small air cooled engine? I have been trying to do that with my ATV to keep it a little cooler...

[@Forcefed2002]

Fuel cools. Not just the intake tract, but the combustion process & exhaust/egts

[@StrikerFin]

Lol, you’re transforming into a werewolf!

[@themaconeau]

Does the dog hair add 50% extra experitse or 75whp? 🤔🤣

[@aarondubose8647]

If you cant fix it with duct tape, your not using enough duct tape

[@euba0149]

I haven’t finished your video yet I’m only 7 minutes in but IVE HAD THIS IDEA FOR YEARS TO PUT A MUFFLER ON A DUMP I CANT WAIT TO SEE HOW THIS COMES OUT JERMEY YOURE MY SUPER HERO😎

[@JohnRoberts71]

Great content thanks for sharing. Very informative

[@Matt-xw4vl]

great vid....get yourself a lint roller with all them dogs lol

[@macro820]

Doesn't it make more sense to put the water cooler after the heat source before the res? I think that would slow down the res heating up. Can you plumb it both ways and monitor the res temp?

[@DayRider76]

Busted? You're having an affair with Holley, aren't ya!

[@DayRider76]

my wife knows what the oil light means? Modern subis turn on at a qt low! Double win, stick a couple extra quarts in the back. That's her problem! lol Maybe she should let me drive the car I bought her more!

[@blake3180]

Your wife might need a brake job soon .. lol by seeing the fluid level.. btw love your freakin channel man 🤘🤘love your bad ass builds and I love how you explain everything your doing in your building projects and even amazed that you share a few tuning and mechanical techniques . Props to and your beautiful furry family man.!

[@gearheadhuff7853]

Hey great video as usual. I'm new to HP tuners, question how can I add fuel to my set up. It's 5.3 with , 585 lift cam, my fuel trims are in the+15. Just want to get it safe but not sure how. I am running a MAF.

[@Zmarshall910]

hey maybe throw a lint roller on that shirt before filming next time.

[@whosurdaddy8907]

Lol the Nordstrom bag in the back of the porky

[@jameshesler7850]

I have suggestion Jet performance has a better mass air sensor

[@DarrenCoull]

With that throttle body angle, could you get a CNC milled adapter plate that is a wedge shape? Would bring it all out a few MM further forward, but the angle would be better for that intake flexi pipe. It looks like the stock angle wants you to put the intake on the driver's side :-)

[@nordic5490]

Ok, so you spent $1k inc labor and gained less than 5% more hp ? Won't be felt in the 'pants' dyno. Just get serious with that pully and the exhaust. Is that air box and filter combo choking things up ?

[@gordowg1wg145]

Ah, as I understood it, with direct injection it can, in theory, be applied at any time up to, and including, the ignition point - I say including because I understand some lean burn applications direct the fuel to the ignition location to ensure a richer mixture for initial combustion? I haven't seen all your videos but what have you done to optimise the air filter and, more particularly, the housing design - that could be a big part of your pressure drop? Oh, really like the way you are looking to optimise all the various aspects rather than just 'bolt on a pulley' as so many other 'tuners' do - you should get gains everywhere. With the scorched rear end, since you are putting a lot more heat energy into the exhaust, the whole thing is going to be hotter, all the way to the tail-pipe - perhaps some additional heat shielding and, maybe, some thermal barrier paint on the exhaust system might help? Especially as if it is stationary it is going to be radiating something fierce to the surrounding parts with no cooling air. With the clamp, just use two joined up next time, for testing and even permanent use if need be.

[@sunnyray7819]

3.7"? Are you trying to go metric but don't know how? Do let your friends see this...

[@Garage_Built_Classics]

Holy dog hair batman

[@robertjohnson4784]

Jeremy you are truly the mad scientist working late nights in your laboratory LOL God bless you for all the videos you truly do explain it love the Nick Williams stuff also keep up the work always supporting you

[@chrissoto1657]

Start looking for video sponsors! You're stuff is top notch always and family friendly. That's a good recipe for the youtube algorithm.

[@Carstuff111]

Hey man, awesome to see the prototyping process in action :) And admit it, when building race vehicles, and its a bit oddball.... Well, you are just prototyping :)

[@christiancapps9896]

I've bent those intake tubes using a brush torch used for burning grass. Heat it up evenly and they bend just fine no kinks. Then cold wet rag to make firm again. Muffler on a cut out what the phuc

I appreciate how in depth you go with the mods you do. Even the stuff we may not NEED to know you tell us, and I like being over informed "edit" much more than the alternative.

[@Studio23Media]

My first car was a Mustang that came with a big air intake. Being a newb, I thought it was so cool...until I learned it was a big piece of pvc painted black 😂😂

[@johnhamblin12201]

Jeremy, thank you for accurate and scientific testing. Very few people take the time to do things correctly. The results skewed to make a certain part look good or make the video more interesting. Again thank you for the awesome videos!

[@I5ZQ8]

What are the advantages of going with the newer lid on the blower? I have heard they pick up power but not sure and probably won't fit. Just curious.

[@AReaux2000]

Did anybody else notice the dog hair on Jeremy 😂😂. I’m guessing the pups are still doing well. Tell Norman I said hi

[@trainsbangsandautomobiles824]

Wait... $900 for one pulley?!

[@buggerlugz6753]

The big question today. looking at his t-shirt, is Jeremy's beard moulting?

[@jasontruman1215]

Simon Wells no but his dogs are shedding I’m sure

[@cory0702]

I really like the way you look at performance. Would you be willing to look at my challenger srt and see what improvements could be done. Thanks Sid
