    Hey there fellas I just wanted to get yall's thoughts on these 2 upgrades and if they are worth the money. Now that we have the cams and cai installed, would either or both of these give any improvements? My boy also wants to install some lth's in the near future and I know those will help wake her and...and the neighbors lol. Thoughts? TIA

    worth the money? That's debatable. What is your goal? If you're looking to make 400+ to the tires, don't waste the money on the mods you are looking at, just get an SC IMO. If you're not looking to make that much HP, I would get the LT's first, I don't know for sure, but I'm thinking the gains from the throttle body will be zero, and minimal for the intake.

    We aren't looking to go FI in any form...not sure a 17yr old needs that lol. Just looking to get all we can as far FBO mods. We definitely dont want to waste money thats for sure.

    $1300 cost to buy the FRPP intake manifold with 62mm TB, plus $150 tune all for a mere 13rwhp gain? You decide.
    IMO there are much better ways to spend that amount of money e.g. upgrades to suspension, tires, brakes, appearance mods, your boy taking an advanced driving course.
    Long tube headers are another one of those mods that don't deliver much bang for the buck unless you find them used (or new but cheap) and it's a DIY installation. If you were to buy $1200 headers, pay $800 for installation, and $150 for a tune, that's $2000 for a mere 16rwhp gain.
    If you combine the cost of the FRPP intake manifold, 62mm TB, and LT headers which would only yield ~30rwhp, you're already halfway towards buying a supercharger or turbo kit that could yield ~150rwhp. Food for thought.

    Oh wow that is eye opening to say the least. I would assume we couldn't use the hot rod cams with FI?

    The hot rods work fine with forced induction.
    Here is an article form Muscle Mustangs and Fast Fords Magazine and a quote from Jesse Kershaw about a set of prototype blower cams that were based on the Hot Rods:

    http://www.mustangandfords.com/how-to/engine/mmfp-1109-3v-heads-and-cams-testing-on-the-port-side


    "These cams have less overlap, more like an 'RV' cam, which is good for torque and keeping the boost from blowing through the combustion chamber," says Kershaw.

    He did tell us that lift was the same as the Hod Rod cams, but duration and the exact difference in overlap will remain a mystery. If you've heard rumors about a new set of Hot Rod cams specifically for supercharged engines, then you can rest knowing that these are, in fact, the mysterious alleged camshafts.

    Unfortunately, though, Ford Racing put the brakes on production of the camshafts because of their lack of power at high RPM and negligible gains through the midrange. "For max power, the Hot Rod cams are the way to go, because while they will lose some low- and mid-range torque and power on blown cars, the engine really needs the overlap at high rpm," said Kershaw. "We like the Hot Rod cams even in blown cars."

    I have the FRPP Intake Manifold and 62mm TB naturally aspirated (along with long tubes, cams, cai, underdrive pullies, 92 octane tune, blahblahblah). The car runs like a bat out of hell, runs healthy and pulls hard.

    But I bought the car with the intake manifold and TB already installed, for a hell of a deal. And I plan on boosting it eventually. Would I have spent my own time and money building the same setup? Probably not, I'd honestly do what these guys are saying and go straight for a supercharger.

    But I will admit, I love the current setup. Guess it also depends on what you'd be running with the setup as well, especially the tune. I've heard the FRPP Intake Manifold and those Hot Rod cams lose a lot of bottom end.

    So just for hypotheticals...what SC would y'all recommend? My boy has mentioned a procharger. What are we talking...$6-8k or there abouts for everything it would need?

    You can do it for 6k pretty easy if you do the work yourself. I, and I'm sure a few others, would recommend the DOB setup. It will max the current potential of the stock engine, and also be good for future power goals if you want to build the engine or something.

    Here's a link to the DOB site: https://www.departmentofboost.com/

    He's got plenty of information there about supercharging the 3v.

    It depends on where in the rpm range you want the most torque. A positive displacement supercharger such as the 2.3L TVS will reach near maximum boost from just 2000rpm and will give you a flat, broad torque curve with the feel of a N/A engine of much bigger displacement.
    In a centrifugal set up such as the Procharger, boost builds progressively as rpm increases, so the engine only really "comes alive" at higher rpm. You can achieve a higher HP number with this set up as boost above 6000rpm is typically higher than what you'd get from a TVS, but peak TQ would come higher up the rpm range so you'd need to keep the engine in the top 1/3 of the rev range to access the best performance.

    Great job on the build so far and write-ups!

    IMO for the street a twin screw is the way to go, I had a saleen sc (they don't make them any more) on my car for years, worked and ran like a champ, instant torque, great power band, but at the end of the day it is what you prefer.

    If you plan on going with FI in the future, just wait on those things. Save your money and get what you want that will net you some good power gains. The manifolds and TBs don't really make much gains without the use of cams and a 'free flowing exhaust.

    I'm just going to drop my two cents right here and do can do with it what you like. As a mother I would NEVER put my 17yr old son into a race car. The stock Mustang Gt goes fast enough for a young driver. Yes I see no problem in making his car look cool and even sound nice but thats where I'd draw the line IMO he doesn't need to go faster until he's older and wiser and a more experienced driver. I understand wanting to build something with your son and thats a great thing just be careful you're not building a car that will kill him or you may find your next project is burying him.

    Agreed, if you had asked me at 17 years old if I could handle a 400hp muscle car, my answer would have been an unqualified Yes. The same question for my 25 year old self, would have been No, and my current state with 3 kids and one 5 years away from driving, the answer is Fuck NO!
    Friends and peer pressure can be a lot to overcome for someone under 20 years old.

    Oh for sure I wouldn't even think of letting him go FI at this point. I was asking more out of curiosity than anything and what would be best and what it would cost. As far as the lth's and maybe a TB for 15-20 hp, that I can live with, as I dont figure you would even notice that unless you put it on dyno to actually see it. I totally agree with you on 17 yr old not needing a race car by any stretch of the imagination. Your .02 cents are totally fine with me man. I don't get offended that easy :)

    It was more about the conversation with you guys and learning things that I don't know.

    What he said. Another point regarding centrifugals, because they build linear power the same way the engine does, vs. instant torque, it's a more natural transition f
