So I have noticed that everyone supercharges their trucks and there is not a lot a turbos out there. By book a turbo is more efficient because it runs off of "wasted" air. I want to be different from everone else so my truck stands out. So what do you guys think of running like a t3/t4 hybrid twin turbo kit vs. say a roush or something?

 

HI!... There's a ton of guys around with turbo trucks here. Don't waste your time with a twin turbo set-up. Go with a single t-67 or if you want more power go with a t-76. Our trucks have a ton of low end and make decent H.P N/A so they have no real problem spooling up the larger turbos.

 

Single turbo is perfect for our setups. I have been doing them since the start. The T-76 is the perfect turbo on the inlet side. Now depending on where you want your power is when you choose the .81 ar housing or the .96

the .81 will allow for super fast spool. Mater of fact it is full spool almost instantly. the draw back is you sacrifice top end. the .96 spools slower but allows for more top end power. Daily driver setup the .81 is perfect. Daily driver and alot of track time, .96

the .81 will hit you in the 700-750 range, the .96 will bump you another 100 or so.

 

Tons?

 

HI!... Yup, visit the LIGHTNING page once and a while...........................

 

I still wouldn't say tons...it's a fairly elite crowd, if even that. I read ALL forums active topics (including L section) and very rarely see stuff on Turbo L's.

Basically, the consensus is that superchargers are cheaper, more readily available (in kit form), and easier to tune since there is a lot of common knowledge out there already.

If you go turbo expect more initial cost, and a longer road to happiness because it will be hard to get it tuned and running properly.

I'm with you on the turbo being better... but sadly not many people realize that, so the after market demand is low.

 

he is not talking about here. He is talking about the lighting boards like talon and nloc etc. There are quite a bit of L's that have done the conversion to turbo. Plus it is not just the L's that have done it. I personally have built 20 trucks with turbo systems. Tuning them is no problem. I have been tuning them since day one. Any knowledgeable tuner can knock one out.

There are several manufactures out there building kits as well. Some more reputable that others, some quite a bit on the pricey side.

The initial investment will be greater, but not by much when you consider you get everything needed, including the tune in most cases. If you were to purchase a blower, headers, fuel pump upgrades, tune - it would cost the same as the turbo. With the turbo you pay for everything at one time, instead of taking steps like you could with a blower.

Power wise:
01 5.4 ATI 12 psi - 375hp - 408 ftlbs
same motor turbo 12 psi 408 hp 506 ftlbs
These are also on a stock motor

 

I respect your work and what you have done but I disagree in terms of your tuning statement . And so we are on the same page, I am talking about the 04-07 F150 3v motors which is what the person who posted the Q owns. Tuning our trucks is a major issue that continues to be overlooked when people bring up the supercharger vs turbo debate for the 04-07F150

 

I'd have to agree with anaheim_drew. Not from personal exp. with F150's, but with Pontiacs (GP's & GTO's) I'm gonna have to say that tuning a turbo set-up properly is much more difficult than tuning a SC.

A canned tune will work for the most part with a SC with more that can be squeezed out with dyno/road tuning.

Canned tune on a turbo?! Almost totally unheard of.

Most 'tuners', unless they regularly play with turbo's won't be able to "knock one out".

 

I agree the turbo's are a bit tricky, and a canned tune will not work. it will need to be tuned on a dyno. I am sorry if there was some confusion there. And yes the 3v is tough, I did not notice it was for a 3v, I saw lightning and assumed, my bad

 

No it's not your bad since your initial answer and follow up was based on someones posted assumptions. Imagine that

 

HI!... Well I can read and NO WHERE in the 1ST post does it say anything about turboing a 5.4, 3-valve. Just turboing our trucks (F-150) in general.

Just so you don't have to go back up to the top post, I'll copy and paste it for you to re-read again.

And further more it does not state what truck (year) he has........................

 

No info on what he drives but it made me think 04-07 when he asked for a comparison using the Roush instead of others used on pre 04's like KB, ATI, etc.. 1.Next
Just turboing our trucks (F150) in general WHAT? He wants to know what will work on his truck.If you had looked at his 8 post you would see that he owns an 06. But it was easier for you to assume and make your normal @#$% comments.

Maybe if you were not so full of @#$% your head would fit where it belongs

Turbos are more efficient because they run off of exhaust pressure instead of being drive by the engine. Superchargers run off of a belt thats connected to the engine, so you give up some power by running the blower.
Turbos do have some turbo lag, but with a bigger engine its not as much of a penalty as it is on a small 4-cylinder engine.
I personally prefer a supercharger because its less complicated. You dont have the turbines in the rear of the truck nor the intercooler plumbing and added radiator. With a supercharger you basically have an added pully on the engine, another belt and the blower. I also prefer a supercharger because there is no lag.
IMO, unless you are building a truck to be the ultimate drag strip weapon, you wont see any advantage with a turbo and a supercharger will be a lot simpler and less of a hassle.
