front mount turbo vs. magnacharger for DD

The only maintance i have ever done with my STS kit is keep the filter clean and clean the mud off the turbo
.Not only do i drive my truck all the time but i also tow alot. Just recently got back from towing a big box trailer to Louisville, KY from CS, MS.. Trailer weighed close to 5000. So not only would i drive my truck across country, i would tow just about anything across country.
Only thing ive ridden in that was SCed was Ranwalk's truck while we were doin a little tuning.. but it was a Procharger.
what i like about a turbo is while towing and you hit a hill and the engine loads up, it builds boost and off you go

I'll even post my opinion. I'm sure my buddy will respond to my thoughts.
Magnacharger... My personal favorite even though some wouldn't think so. I like this system the most because of it's low maintenance. The TVS series has reasonable IAT's with a good heat exchanger setup. The best part about that system is that the only piping on the system is the intake side which is only vacuum. Boosted pipes are more likely to come loose or blow off. This is the best part of the put it on and go to the system. Once it's installed if it's done correctly you won't have to do anything other than check the belt at every oil change, change the belt about every 30K, and change/clean the air filter every 30K. A TVS2300 is about a perfect choice for a street/strip boost level 6.0L. Street boost to me is 8-10psi and up to 14psi for a strip use. My personal opinion is that the TVS1900 is too small for a 6.0L. Yes they do make very good power on the 6.0L, but in order to make 10psi of boost if you have headers and a mild cam you have to go to a very small blower pulley. Keep modding from there and you'll have to overdrive it. Chosing a TVS2300 up front just give you the room to mod as you'd like without ever having to think about changing your drive system for any reason other than going to an 8 rib. My opinion on this will show itself as you find the modded 6.0L guys using TVS1900's overdriving them to get the boost levels they want (or boost level's they'd have gotten if they'd have just bought a TVS2300 in the first place). Drivability and part throttle boost is very smooth and linear with the TVS blowers if tuned right and has a stock yet very torquey feel to them. The boost comes in off idle and as a result a stock converter or low stall is all that is required. No doubt for any street/strip truck right now a TVS2300 with a 2 bar tune is the way to go.
Front mount turbo... Trick, KB Racing, Livernois, etc. all make very nice front mount kits. The front mount turbo can't be beat when it comes to all out power. Underhood heat is the downside to a front mount turbo. This also brings the boosted tubes down to a possibility of blowing off. Yes if everything is installed correctly it is rare, but I think every turbo guy has had this happen at one time or another. Due to turbo lag you have the choice of either planning to boost launch every time you want to race someone or you buy a converter with more stall than you really would like to be able to get a good launch. Turbo systems offer the ability to pick one of many, many turbo's and leaving you the ability to tune the turbo to your setup. Options like ball bearings, extended tip wheels, exhaust housings, downpipe size, etc. Boost doesn't change quite the same as it does for a blower when it comes to altitude because turbo's rely on a wastegate to control boost so they have the ability to make the same boost by just changing the amount of exhaust flow past the turbine. A blower isn't really designed to self compensate like this and requires a pulley change. Drivability is great with a turbo, but don't stay into boost for too long as you can end up with very high EGT's and end up killing stock pistons. The ability to turn the boost up is great and yet sometimes too tempting, lololol. For all out power I'd pick the turbo. It's just not my choice for a street strip truck that is more street than strip.

Like it was said, if you want set it and forget it, got with a TVS2300. The initial cost is pretty high (relative to a single turbo) but it will make a ton of torque down low and still had a strong top end. I've never owned a Maggie truck but I have ridden in a couple. It seemed like the MP's do run out of steam but it sounds like the TVS's have gotten past that.
I'm probably just jinxed myself but my Turbo kit has been 100% maintence free for the 6-7k miles I've put on it. The downside to that worry-free was about two weekends and most of the evenings in between making sure every little pipe/hose/fitting/wires/etc was in just the right place or heat wrapped before I ever even tried to start it up.
You could always go with twins. You'll have 90% of the bottom end your looking for and for all intents and purposes, an unlimited amount of top end. I run 10lbs on a totally stock LQ9 (other than springs) and am pulling around 550 AWHP and not even stressing the motor too hard. Put in a forged shortblock with the same kit and it will max out at over 820 RWTQ/ 847 RWHP (This is an old post but has the most recent dyno chart on page 5 - https://www.performancetrucks.net/fo...=399761&page=5 ). I have about he same $$$$ in my system as buying a TVS2300 and DD wise I couldn't be happier. I love the big top-end power and winding the crap out of it but my favorite part is the DD mode around town and on the freeway. I'm running a bypass valve instead of a blow off valve so I just set it a the minimun tension to close and full boost hits at anything more than about 1/3 throttle. The bypass keeps my mileage up on the highway (about 14.5 mpg average) and give it another 1/4 throttle at 65 and it instantly has 5-6 pounds boost and your at 85 without dropping a gear or any drama. It's like driving around with a 500" big block.
Either way, you'll be happy (and broke)...
