3200 is way too high. If you get a stall like that you'll need better gears. If you have stock gears stick with under 2000. Talk with someone at lentech. They will give you good advise. Also your trans will definitely blow up in no time with a stall like that, especially if it's stock.

Thanks man. I'll give them a call.

My truck has a lightning swap with an Eaton supercharger, all stock lightning parts besides the exhaust and the only transmission upgrade they did was a shift kit. I was told by friend who owned the truck before that they tried putting a stall torque converter in it and the transmission didn't last very long, I didn't get much details but they said in the end the shift kit was the best option. Very cool build btw! I love my supercharged 5.4L really wakes it up!

This comment pisses me off!

I'll step in to say this. I took the time to answer every question you asked due to EXPERIENCE, not just from what I read on the Internet. Myself, Jbrew, 4X4Dave and many other have huge knowledge of these truck. I'm willing to bet just between myself and the two members I listed have more knowledge about boosting F-150 than most shops! And we come here to help people for FREE! And then we get told we are wrong and the shop knows best!

If they know so much why are you asking US these questions?!?!

For sound & flow I'd go with a straight through design as it was said already. I had dual 2.5", Y'ed into a single 3.5", into a Aeroturbine 3535XL diesel muffler out the side like a Lightning with 3.5" pipe and a 4" tip. I have gotten many compliments on it, most coming from Lightning and Harley guys. Flowmasters are a sound muffler only IMHO.

A shift kit and additional cooling to the 4R70W is by far the best mods you can possible do to it, PERIOD!

Yeah since it's used I was a bit wary. The previous owner said it had been sent to vortech approx. 5000 miles ago and upgraded to Si trim which according to vortech changes the straight cut impeller to a helical impeller. I emailed vortech yesterday with a link to the video to see if they thought it was on its last legs or what have you.


Thanks,
Mike

You make a good point, it was a gesture towards a different individual and apologize if you took it as if I was suggesting I didn't trust the information being provided to me. I most definitely do appreciate it otherwise you're correct why would I ask.




The shop doing the installs specializes specifically in ford modular engines is all I meant.

There are a lot of choices and opinions out there when it comes to products, and not everyone will like the same products for various reasons. The best thing that you can do is research. Call each manufacturer of the products that you’re interested in and make sure that you're getting the right information for products based on YOUR specific wants and needs. Sound is an individual preference, so buying based on someone’s opinion of what they like, may not end up being what you like or want.

Flowmaster's chambered muffler design is based on basic principles of physics. One of the advantages of Flowmaster's chambered muffler technology vs. a comparably sized ‘straight through’ muffler is the interior volume that each muffler can handle. Think of it like this- take a 2.5” inlet/outlet ‘straight through’ muffler (which is just the volume of the length and inner diameter of the tubing passing through the muffler) and fill it with water and then dump it into a measuring cup. Then, do the same thing with a comparably sized 2.5” inlet/outlet Flowmaster muffler. The Flowmaster muffler would hold considerably more water than the ‘straight through’ 2.5” piece of tubing. This added volume allows less resistance (more volume for the exhaust inside the muffler) and a ‘relief’ vs. the same sized tubing of a straight through design. Another benefit is, as the exhaust splits and travels around the deflector (the V shaped baffle) and joins back together behind the deflector to exit through the collector, it does two things. First, it creates an area of low pressure behind the deflector resulting in a “pulling/scavenging” effect and helps pull the following pulses through the exhaust. Second, the deflector acts as a one way check valve and eliminates the sound waves and exhaust gases from reversing and running back up the pipes to the engine, messing with the tuning. The end result of this added scavenging is a cleaner burn in the combustion chamber because you're affectively reducing the contamination (unburnt gases left in the combustion chamber) which = more TQ and more power.

[MENTION=188153]Gorilla978[/MENTION] I myself have not boosted my truck it is N/A. I have tuned several lightnings along with several other boosted F150's. A stall converter is the wrong way to go because of the weight. The best thing you can do is a shift kit and a really good tune. Its a truck not a mustang. I assume your truck is also 4wd. So even somebody who tunes lightnings will have to do a few changes.

Back to the converter issue. I have a 2200 Twin Disk Billet Suncoast converter that is spec'd for my current setup. Even with a rather light load 3k-5k lbs it will flash to around 2800 before the truck even moves.If you towed anything it would be worse with a 3200. Also the trans would be able to handle the load applied to the transmission with a huge stall converter. Being your truck has stock cams it will be better off with tighter converter AKA stock.

As far as making the truckc more punchy, I would look into a different pulley setup. The vortech is made to make peak boost around 6500 rpms or so. The peak boost is very dependent on the internal gearing. If it was on my truck I would have a very aggressive pulley setup so that the blower would reach peak boost around 4800.

As far as your muffler choice its mostly preference.
[MENTION=192252]Matt@Flowmaster[/MENTION] There is no need to spread your thoughts or designs of mufflers around here. Those who are looking for peak performance knows the truth behind flowmaster mufflers. I know for a fact on a dyno that they cost hp for sound.

FlowmasterMufflers

Extensive testing is done at our full-time Research & Development facility with a Super Flow engine dyno, 4-wheel drive chassis dyno, race teams, engine builders, etc. for developing mufflers and exhaust systems. Flowmaster custom builds and tests multiple mufflers, tubing sizes/configurations etc. when developing systems for each and every vehicle that we release for sale. This is done to get just the right sound and proven performance gains on the dyno, or the system doesn’t go to market. As for negative results, we have no control over what others may be changing besides the muffler, and how all of the variables coming into play with all the changes made, effects the overall performance...especially with the ‘knock off’ or ‘copy-cat’ products that are out there.
