I had a 2004 Subaru WRX STI (Turbo) and loved it. It really depends whats your going for. With a turbo, you have the top end more. It depends on your setup and the turbo lag issues (based on turbo size). Once the turbo spools, it is HOLY HELL!! time. I have never had a super charger, so I can't comment on those.

I think a supercharge will give you mroe of a constant power feel, where a turbo will be a "kick in" power type thing once you get going a little.

Either way, you can't lose.

Thats why they made this lil invention called a INTERCOOLER. $300 investment + piping and HEAT is no longer a factor. GET A TURBO! Superchargers are worn out and have limits. TURBO's are limited to the size you are putting on. DONT MAKE A MISTAKE> PUT A TURBO ON!

For the money, for the reliability and for the long haul (on a truck) I still think I would go for the sc. Now if I wanted to go fast in my Stang I would most likely do the Hellion (or ??) twin turbo with the intercooler. Unless you want to race your truck, and maybe you do, I just don't see the need for a turbo. With the plug issues that our trucks have, I think a turbo with high boost would cause more trouble that its worth.

Yea, putting a Turbo on a truck is stupid. I mean all the 3/4 and 1 ton trucks are all SuperCharged so why not supercharge. Wait a second, they all use TURBO's!!!! Maybe a TURBO on a truck aint that bad of an idea afterall huh? I mean, if its good for the big trucks, why cant it be good for the midsize trucks as well? Tell you what, put your supercharger in, and contact me and we can line up and prove to everyone which is better, Supercharger or Turbo on an F150.

turbos are much more realiable than supers. exactly what vano said above me. the heat issue isnt a big deal anymore. i think a sc is easier to install but turbo will get you more bang for the buck and more reliability

okay, i'm not a boost expert, but that sounds wrong. now 12 lbs boost is 12 lbs. regardless. and will net the same power. now i'm not saying a turbo and supercharger are the same, just your theory is off a little. correct me if i'm wrong. the way i understand it is a supercharger set at 12 lbs of boost will reach 12 lbs at the top of the rpm band or close to it. now with a sc, you'll have constant boost, so you might get a little bit more power at lower rpms. but with a turbo, once spooled up, typically around the 3000-3500 rpm range will be at full 12 psi throughout the rest of the rpm band, giving it the advantage. also, with a turbo you remain in a vacuum/ naturally aspirated state while at low rpm. so basically, your truck would run as it would normally. once you get on the gas, the exhaust creates pressure that spools the turbos up and starts creating boost and only then are you really running forced induction. definite advantage. less wear and tear for normal every day driving. i also like that it hits full boost earlier in the rpm range, creating more power throughout as opposed to hitting peak boost at peak rpm, only to shift and drop back down in pressure with a sc. thats why sc's seem slower but yet dyno good numbers.

someone said something about heat causing problems... depends on where you mount the turbos. if you do a rear mount, heat build up isnt that big of a problem. closer to the motor and it will run a little warmer. but i dont see it being so much of a problem, as most quality companies provide heat shields for the turbos to help reflect the heat from nearby components.

heh, i get what you're saying, but turbo diesels are a slightly different setup than a turbo gasoline motor setup. diesel engines run primarily on compression and have special designed turbos to keep them in constant boost. unlike a gasoline motor turbo, as it allows the engine to drop into a vacuum state until a certain point when the turbo spools up and changes into a forced induction. gasoline motors have spark plugs to allow for combustion. i know i'm reading into the statement, but just a little fyi.

i guess i should also ask what you want the boost application for? are you going to race the truck? if so, a turbo will net a faster time. for constant power at lower rpm's for while hauling a big load, i would probably go with a roots SC application. it might not outperform a turbo in a race, but will net you more power down low and build with rpm.

Looks like the Squires Turbo System is very pratical. Plus it gives you 100hp add on power.
