Just courius to see who is running what. I know STS says you can run pump gas with their systems. But I know somebody with an TBSS with STS turbo that now needs a new motor. He was running 91 octane and 5 pounds of boost at the track and it detonated. I haven't heard any other motors going out at that low level of boost:dunno:

Maggie installed and running 91 octane for the most part. If we know we are going to run though, will get 100 octane.....1/4 to 1/2 tank only though then just mix 91 with what is left of the 100. Followed Joes'(Left Coast32') advise and replaced the stock plugs with NGK TR6 gapped @ .035. Runs 2 degrees cooler and less chance of detination with the maggie that is, don't know about the STS. Oh yeah, running at 5 to 7 pounds of boost and no issues as of yet!:dunno:

I run premium all the time. As a treat I just added a 1/2 tank of 111 octane race fuel to the 91 premium in it. I could probably bump the timing up a bit on this tank but I will leave it the same.

I did a run today and saw the boost needle at 8.5 psi of boost right before redline. Remember that I have a forged bottom end, 11 to 1 compression and head studs with cometic gaskets. This is the reason I can run the boost levels I am.

I hope to have the boost levels in the 10-15 PSI range with the new testing we are going to do. I will be ordering the L92 Heads, Cam and put it all together with the new Blower that is being developed. The new system should be out the first or second quarter 2008. I should have some good data to post up when testing is done on my TBSS with it.

Tuning makes all the difference in the world. I run 5psi on the street and 7psi when I feel like causing trouble. The truck has been turboed for almost 4k miles now and it has had the stock tranny 3.5k miles of that. The tranny didn't break I just replaced it before it did.

High compression and boost don't make for a safe enviroment but with proper tuning you can make the truck live safely for many miles to come.

What type of tuning do you have done? STS recomends the predator diablo. The TBSS above was completly installed and tuned by STS in Orem, Utah. I don't mean to slander STS in anyway I hear they are great to work with and will probably get this guy a new motor. Will find out more in the morning when I go to order my nos kit.

Octane = the highest you can get . I have been tuning Turbo TB SS since Feb 06 [ The first one ever] and can bet you he ran out of fuel . The demand for fuel in 3rd at high load is insane. The hand held may work ok but it has it's limits thats for sure. Don't bet on that new motor STS will get. LOL
We are the first Turbo truck to run 12.0 at 117mph with a stock trans and a tight stall [2600] for over 10k . The STS kit leaves a little to be desired as far as pluming goes with 47 90 degree bends. lol but there is alot . As for you built Maggie guys I wish you where closer to us ..I got somethig for you.

STS should be starting to reccomend our tuning to go along with thier kits. They told me they like to offer a selection so thier customer has an option before they buy a expensive locked tune they can't alter later down the road. We just completed some R&D work for them about 2-3 months ago. You know anything could have happend on the truck that let loose (it wasn't me who tuned it obviously).

I'll have to agree that tuning a turbo is not like turning a supercharged vehicle. You have to take alot of care that they will be corrrect out on the road.

As far as the STS kit quality goes.. I'm highly impressed with it. It looks great, fits very tight, and doesn't rattle. It fits better than some of the blower kits I've installed and definately way better than any turbo kit i've done.

That sounds like a few stabs at the Supercharged guys so I feel it is only right to stab back a little.

I applaud you for helping with the tune and actually getting it done. The tuning for any forced induction application is hard from the start. It is always easier to tune from a base tune like offered with the unlocked Magnuson Tune.

The tuning for the Turbo is only different in that you will have to make the tune compatible for different boost levels depending on whether the customer gets a Variable Boost Controller. I have had Turbo's in the past.

The Rear Mount Turbo first off is good for a vehicle that has no under-hood room. A turbo mounted off a log style manifold where the exhaust has more heat and velocity will be more efficient. The tubing running from the rear of the vehicle can never be as clean as a front mount turbo or Supercharger.

I'm not taking a stab at the magnacharger at all.. They are pretty involved installs with removing the bumper and everything but it all fits like a glove. I bolted the STS kit on in less than a days work taking my time. It fit really really nice and its super clean. I meant a few of the blower kits I've installed and definately all the turbo kits i've done have taken a good bit of messing around to get right.

A turbo is difficult to tune because boost is always a variable and a blower is pretty consistant on boost therefore a bit easier to tune.

Have you seen a STS kit up close for the TBSS? Theres not a whole lot of indication anything is there. Most everything is tucked up under the frame and you can't see it unless you get underneath the truck (peaking under you can see it).

I agree that the kits are our competition and I have viewed the kits first hand and looked at many pictures. They have done a nice job with all the tubing.

The tuning for boost as a variable is now getting easier with the '07 PCM's. The new parameters in the 07 ECM's are able to handle more change.

The turbo's have always been a finicky tune even from the beginning. My 1992 Typhoon was a monster but needed much to increase boost and tune. I had to have 3 different tunes and different things to make sure of during the different tunes like the octane level.

I am trying to get a bunch of us together in a location that is somewhat central (Maybe Vegas) in the fall or beginning of winter for a get together and some track running. It would be great to get a bunch of the Turbo guys to join in also.

Having owned and sold both the STS and Magna Charger, I can speak FIRST hand on my experiences with both:

Magnuson:
1) Complete and complete can get
2) OE Quality that is hands down the best in the industry
3) Plenty of room to make 500 rwhp with the right combo (who the heck needs more than that on the street?)
4) Customer support from both the manufacture and Left Coast that sets the standard in the industry for the t-others.
5) Instant off idle power
6) Linear power band that has more power under the curve than ANY turbo.
7) Lack of top end (above 5600 rpm) power...that is until the MP122HH became available.
8) E.O. Exempt (dont know of any other TBSS FI solutions that are)
9) Easy one day install for an experienced wrench.
10) 100K miles plus reliability out of the box

STS:
1) Somewhat complete, lacks a few parts that I would like to see in the kit
2) Some fabrication is almost ALWAYS needed with the STS to make it RIGHT
3) Plenty of room to make big power with the upgraded turbos
4) Customer support from the manufacture is darn good
5) A bit laggy for my taste, I like the feeling of having a BIG BLOCK under the hood
6) More of a "bell" shaped power band.....who drives from 4000-6000 rpm?
7) GOBS of top end power on tap with a turbo, makes for fun on the highway
8) NOT E.O. exempt, this is important to members in states that require smog testing.
9) I have yet to get one the way I like it within one day of receiving the kit.
10) TBD on reliability.

Again, I am currently driving a Forged 5.7L STS powered crew cab, and I am not 100% satisfied with the off idle power and the around town drive ability. I changed from a Magna Charger JUST to educate my self and get the experiance with the turbo.....I can say with certain authority on the subject that the Magnsuon System is better in more ways than one for MOST of the end users out there.

Care to debate? Bring it.

I really feel alot of this doesn't match my experience at all. The kit installed super nicely with no fabrication. Also my turbo hits hard as hell and thats coming from a guy who has a maggied 07. He was impressed with it. Also, the only parts I would like to see come standard are things like a good blow off valve.. other than that it was a plug and play deal.. or very close to it.

I also like the turbo sound... You can really hear that turbo inside and outside the truck. I have people pull up next to me all the time and give me a thumbs up. it also brings a crazy amount of attention at the track.

A buddy of mine has a 07 with a maggie. He got his around the same time I got my STS. My truck is consistantly faster. He went up two pulley sizes and it matched my TB's Boost and ET but not MPH. Now that i got a converter in mine (very important with a turbo) I'm 60' about .08-.1 faster but going 2+mph faster and 3.5 tenths faster.


Currently in this hot and humid NC weather with 800ft of elevation (temperatures are in the mid 90's during the day with cooling off at night)
He runs a 8.26 @ ~ 86mph with a 1.87 60'
i'm at a 7.90 @ 88.6 with a 1.79

Both have very positive attributes and I really think you can't go wrong especially with the new magnacharger coming out.
