Any further updates or personal bests from anyone? Great thread --- hate to see it die.

I think you're right. Obviously, the twins would add at least another 500-1200 expense and probably aren't worth it with the technology advances made in the turbo market today. Not sure what you mean by the rpms? As far as the converter remarks, what I was trying to convey was in the "race car" or really fast street car scene a lot of guys will run a big turbo setup with a glide and a high (low numerical) gear in the rearend. So the car cruises nice at low rpms, but when you boost it up the power (torque) will make what seemed like a tight non-existent converter loose enough. Very hard to get the converter right on those cars, either doesn't want to spool or wants to blow through it. My application with the heavy ass vehicle where I really want a tight tight converter may not be as easy or even possible. To be honest, I think I have my direction yet again. I forgot about that combo Zippy and ???? were doing. 408 plus 2300-----went 11.60's in heat and very close (maybe already did) to 10's. That would be a great setup! Problem is, if I have to have a jackshaft blower, phenolic spacer, 102mm tb, 408, etc the cost would almost push towards or maybe well past a properly sized turbo kit..........................There's my dilemma...

LOL!!! Talk about rain on someones parade----LMAO----j/k! You do make a lot of sense though and is probably what will happen if I don't do it right from the get go. I should just put a jy motor in it, pull the blower off and leave it alone ;-) That would be logical and make sense---of course that isn't me lol. I never make sense when it comes to this hobby ;-) As far as the turbo, I would have Diamond Fabrication do it. He's in Warren and is the whip!!!! Very anal and a perfectionist. He's done a ton of turbo kits, etc. Actually, he is doing the intercooler tubing and headers on my mustang as we speak. Very cool guy. Zippy recommended an 88mm unit with the 408 IIRC. I'm thinking possibly that route or maybe some smaller twins. What I would like to end up with ultimately is turbos that spool extremely fast and a setup that allows me to use a near stock stall. Actually, the beauty of the turbo setup is the converter "should" be able to be real tight when cruising around, but should loosen up under boost if that makes any sense. Meaning the extra torque will raise the stall speed. I probably should talk to Precision or Circle D and get their thoughts..... I'm really up in the air with regards to the single vs twins....... Another spin-----------I could or probably "should" just put a jy 6.0 together with a 2300 (non-jackshaft) or even a 1900, pick up 2-4 tenths and call it a day. Maybe do the 408 with the 1900 or 2300 (non-jackshaft) and call it a day......Sigh.......................................

Will probably be the direction I go unless something else good falls in my lap. Probably just do the 408 with "future" plans of either a turbo or bigger s/c.......Decisions, decisions...... I would really like to see what Chase runs with his when he gets it dialed in and leans on it more.

That is how I was leaning before (and may still go), but when you put it on paper the waters get muddied up quick! I love superchargers, but they aren't exactly cheap. Jack shaft blower drive, pullies/cogs to get the drive ratio you want, 8 rib pulley setup, pullies for blower, phenolic spacers, 102mm tb, etc----gets expensive.... My fab guy is reasonable and would build me up a turbo kit for comparable pricing (if not cheaper). When it comes to the turbos, it seems like you can get away with using a smaller engine and tighter converters and still get the performance. Also, when building big power with a supercharger, there is power that is consumed driving the unit. In other words the fuel system has to be able to support more power then the engine is putting out at the crankshaft to drive the blower too. Maybe 75-100hp? I know in the big procharger stuff I play with (race car), that number can be 150-200+ hp!!!! So in other words, I might be able to get away with a lot less fuel system (less $$$$'s) with a turbo too....

Ok, I've read tons of good debates on this subject and even had some threads about it, but I'm still over the page on which direction to go now that I'm almost there. Basically, I have 163,000 miles on my current setup and it is not long for this world. I want to continue to drive my truck year round and use it. I also want it to run 10's (no nitrous). That may be a stretch while keeping its utility/reliability, but I think it is possible----worst case a pulley change or boost controller tweak when I want to turn it up or down. Back to reality, I would probably be happy with low 11's (mid 11's in summer) while staying within some semblance of a budget. 2 areas I'm battling around: 1. Engine If I rebuild it, it would probably make sense to do the stroker (408 more then likely). Flip side, I could just throw a good used 6.0 in it. There have been a ton of stock 6.0's (maybe with good head gaskets/bolts) running fast with turbos........ 2. Power adder I like both so that is a non-issue. I think the turbo will get me there easier and will be more flexible for my needs. My wife has an Ecoboost equipped vehicle and I must say I really like the way it drives.....I have a great fab guy for the turbo kit so I'm leaning that way right now. Thoughts, experiences, feedback? Thanks.

Coming from the two chamber flowmaster/h-pipe on my mustang days, I know what you're saying---lol! But these are 3" which add some noise. They aren't terrible and probably not noisy by most of the boards standards, but they are too loud for my tastes at this point in life. I drive probably close to 50 miles a day soft in mostly city driving. Other then drone range (around 1800-2000 rpm), they are fairly quiet under light throttle, but open it up a little and it gets obnoxious very quick! The drone is nothing like the a 2 chamber muffler, but it is definitely there and quite annoying when combined with the heavy vehicle weight + loose converter + heavy stop and go traffic...... I put (2) of the biggest 50 series flowmasters I could fit on my mustang with an x-pipe back in the day (3") and I loved it!!!! You guys are killing me---lol! My wife has a Lincoln MKT with the twin turbo Ecoboost motor. With the tune, they run mid 13's! I love driving it because I can rage on it and no one around you would know any different (except for the bus lengths!!!!) LOL! It so quiet and smooth! That quiet nasty surge of power is awesome!!! Definitely plan on some turbos for the truck in the near future.

Which part number are you referring to? I think these mufflers I ordered are about the biggest straight through design muffler Magnaflow has. It has the huge 5" x 11" body too. I'm planning to log some runs before I take the flowmasters off, then with the switch to the Magnaflows, then the addition of the resonators. As long as the weather conditions stay pretty similar, I should be able to get a decent idea of any performance increase/decrease from the MAF airflow pid. At least, that is what I'm thinking.......

Don't have it and my system is a true dual system with 3" pipes anyways. There are a lot of people with late model muscle who run multiple mufflers, but honestly I've never paid that much attention to those discussions. Now that I'm interested in going that direction, I can't find any information in my searches.... I think the truck will pick up performance with the Magnaflows and will probably be a tad quieter. With the resonators I'm hoping it will be pretty quiet with no loss in performance. That is what the manufacturers claim I should see, but the last time I listened to a manufacturer, they said these 70 series flowmasters would have no drone due to the built in resonators.........

Well after getting pulled over twice in one month when I wasn't really doing anything wrong/plus hitting the big four ohhhh, I've decided to quiet this monster down. Here is a link to the current system. The cats failed a few months after they were put on so they are now just shells of their former selves Anyhow, I ordered (2) #12589 Magnaflow muffler: http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=9377 ...to replace my 70 series flowmasters. I can't stand the drone that isn't supposed to be there (according to flowmaster) and they are a tad too loud. The flowmasters sounded really good actually, but to get pulled over for 1/2 throttling it from a light and never exceeding the speed limit........... Silverado SS pictures by slowfive0 - Photobucket I think the exhaust note will be better and quieter with the Magnaflows, but I think it will be still on the loud side for the sound level that I want to be at (think how loud a Corsa Touring system with stock cats is and you are in the ballpark). So I ordered (2) bottle style resonators from Vibrant also: Vibrant Performance ::. They will be placed before the mufflers. I'm hoping this will quiet it wayyyy down. If not, I will order an additional (2) "Ultra Quiet" resonators from Vibrant that will be put in the tailpipes. Vibrant Performance ::. I don't want to hurt performance and I want it to be VERY QUIET. I know, that's gay and all. Call me old My race car can be loud, not this. Thoughts? Anyone else run multiple mufflers, etc and did it kill their performance? Thanks guys! P.S. Be funny as hell if the truck goes faster with 6 mufflers, then with the original 2 Flowmasters.....

No, Zippy. He is now located in Phoenix.

Thanks man. That was my thoughts too (low stall). I have a bunch of friends that run turbos (mostly cars) and they run low (numerically) gear sets and tight converters. Cruises at a nice low rpm on the hwy and when they turn it up, it stalls high enough to get into the sweet spot of the power band pretty much immediately! Of course torque is what does this and I would imagine a TVS2300 would active similar.... I'm getting pumped----probably going to be a 408 or 427 with some TFS cathedral port heads and a TVS2300 jackshaft blower. Turbos are still very possible as well. I'll keep you guys posted. Thanks for the input. For sure!!!! I've seen a ton of combos that weren't right and drove like chit! Also, seen a ton of combos that were amazing!!!! I've always been pretty intimidated to do one of these combos as a result. Way easy to get it wrong. The other thing that really sucks to get right with a turbo (IMO) is the converter. And when you do get it right, as soon as you turn up the boost a decent amount, you're back to blowing through the converter, etc.......But when everything is right......

I said the same thing last year (I would be happy getting into the mid to high 12's). You can see how long that lasted --- LMAO! I don't know what yours should run being as it is mostly stock with exception of the charger, but I bet 13's for sure. Tune is a big part of it and will help you tremendously. X100!!!!!

No problem, I totally understand. I am planning on going Saturday if the weather allows. Sucks because it is supposed to be 50-55^ WOW! Wheels would be awesome to see how much difference on my combo. .4 would be incredible---lol! Should be fun though so let's stay in touch. Is there anyone else local on this board who wants to go?

WOW!!! I would do that in a heartbeat! Problem is I suspect I have a spun cam bearing.......... Was your cam custom? Bigger or smaller then the GT2/3? Were either of you guys using smaller wheels and tires or weight reduction? Thanks Kevin.

Ooops, didn't see this. I thought these combos (radix with 6.0's) didn't like a very big cam as the blower was already a tad small for the 6.0)????? I have a GT2/3 right now. What would you recommend? Yep, I like how the meth injection allows me to make back to back hits with consistency and without loss of performance. I also like how it gives me some more octane which is the whole reason I added it in the first place. So it isn't bad, just a PIA to fill all the time. I was hoping for a bigger gain in power that's all. I think it would really shine if I was running a ton of boost and had crazy inlet temps. Kills at the track......Hmmm, let's see. 2012 SRT-8 Jeep cherokee, BMW M6, lots of mustangs and camaros, a bunch more "NO ET" vehicles----LOL!, corvettes, SRT-8 challenger, and more I can't remember. I did lose to a few race cars and a neon....LMAO!!!! This car wasn't even an RT, but it was obviously modified. I tree'd him and hole shotted him. Didn't see him appear in my mirror though----that's when I knew I was in trouble! He blew by me----went 11.80 at like 128! Fun times. Best part is always when "the cool ones" come over in the pits to ck it out. The only ones that weren't very cool about it was the SRT-8 cherokee and the M6 - LOL!

This option is sounding better and better. Will be relatively budget and strong enough it sounds.... I have the bug really bad! For some reason (kind of sad really) I get more excited about this then my race car. I think because I drive this one daily and get so much more enjoyment out of it. Honestly, if I hadn't already got so deep into my car project I would sell it. Just too much money and time to waste at this point without seeing it through..... For some reason, this decision (turbo vs blower) keeps rearing its ugly head and I'm all over the board as a result. I was talking to my builder this morning and we were discussing a recent encounter he had (on the street) where he ran up against a late model mustang with a pd blower (he has a big turbo). They were just screwing around, but he ended up having to play major catch up (not sure if he caught the guy before they shut it down) because in the short time that his car spooled up and came on, the pd blower mustang was gone. Important point to mention is the mustang probably runs 11's and the turbo car is wayyy quicker. At the track no big deal, spool up the turbo to where you want it and go! On the street, different story if you're not ready. Sigh....

We are talking right now and results are already very promising!!! This is the last "official" weekend our track is open and it is supposed to be around 50 and rainy at this point..................That will Suck if so...... Not a bit and I can understand the temptation at this point. That speaker box is Stupid Heavy!!! I'm sooooooo tempted to pull it out and put my tonneau cover back on for starters...... lol

Cool, thanks.

WOW!! Anyone know what kind of power it takes to go 10's at 5600lbs? I should be more then fine then

Also, what about compression ratio, stock block strength and "modified" stock blocks (i.e. extended sleeved blocks from ERL, etc)? Thanks again. Basically, is the stock block strong enough for 10's in a daily driven heavy ass SS? And are the extended sleeves a good addition for the longer stroke/piston setup?

Thanks Zippy! You're absolutely right. For me, I think the best course of action will be to run things like they are until I have the money or break it. At that point, I can do the engine (408 sounds nice) and just run it NA if I don't have the dough for the rest. Thoughts on the heads? I'd rather do them at that time if I can---Was leaning towards the TFS cathedral port design even though everyone touts the newer port design.....Still up in the air on that.....

Well, currently have a daily driven SS with a radix. Absolutely love it thus far. It runs 12.20's, gets acceptable gas mileage and tows/carries what I need it to. It handles pretty decent and does awesome in Michigans weather! It needs a motor pretty soon and I've been all over the page on what to do with it. Basically two thoughts right now: 1) Put a turbo kit on a 370" motor or 2) do a big inch stroker with a TVS2300. Problem is, I've already spent big money on a custom 3" stainless exhaust system and that is kind of swaying my judgement. To be honest, I think I might be pretty happy with a turbo. I have an amazing fabricator and I also have HP Tuners. I believe I can tune it and if I can't, I have friends in the business who can. Doing a large stroker with LSX block, good rotator and heads isn't exactly cheap. Add the blower kit (jackshaft drive) and 8rib pullies and other supporting equipment and the blower option gets very expensive! I wanted to build a high 10 combo (good air) and maybe mid 11 combo in the heat. At this point, I don't care if I give up some performance and retain stock type drive ability. My biggest thing now is a near stock torque converter. I have a converter that flashes at 2800 and I HATE IT! I drive so much and this is such a heavy pig that it really sucks! Gas mileage is horrid in stop and go traffic and it has to go. This is where a turbo would really shine. Small cubes should be good on gas and converter can be relatively tight. When the boost kicks in, it will stall higher----lol! I think if I put it down to dollars and cents, the turbo/370 (budget rebuild) will be cheaper.......Thoughts on this? I really could use some insight here as I need to make plans soon. Thanks guys.

BEAT ON IT!!!!!!! at the track Oh, I did put a 90mm tb on today.

Sounds great!!!!! Just what I've been thinking of. BIg torque!!!!!!! Can't wait to see
