single vs twins please help im not trying to start a flame war

I love my big single. There is nothing else like the rush of when a big single lights. But for your application twins will be better. If you are all the time getting on your truck on the road a big single will come with alot of smoke and lag compared to the twins will always be there when you step on it.
I have always said turbo lag is just a courteous head start

We need a manual valve body. Just like with a hot rod gasser, if you want to street brawl, you need to be very aware of how big of RPM you're swinging before you whup it out.
From a 3000rpm punch a big single is violent. If you try to pick a fight at 2000, you're going down in the first round.
i run mpi twins, 6" lift, race with 33's, my time is in my sig, use it for work everday, pull very heavy with it at times.....my fuel mileage actually went up 1.5 mpg....you know where my vote is!! Good luck!!
Hmm this gets me thinking. Id really like to look for some more power, nothing crazy, but now what im reading about twins has me wanting to do a twin set up. I do use my truck everyday, from DD, to work, to hauling shit for work(pallets of versa lock block) and would still like to maintain that ability to do so.

I will be the lone guy with a gt4088r. I love it compared to the stock turbo. Spools way faster, truck pulls harder, mpg is up almost 1mpg daily driving. I really don't have any complaints. I was ready to do twins and decided on the single since I am in Cali and will soon have smog inspections.(still looks close to stock). I have not dynoed the truck with it, but figure lift pump and a single stock cp3 I should be atleast 550hp at the wheels, which is enough for me at this point.

We started with the GT4202r kit on the stock-the lag sucked. We then had to do some mechanical work due to a coolant loss issue and built the stroker. We started out with the R and Pats tune but then got convinced to do the upgrade to the GT42 Mag and the lag still sucks but when it lights you quickly forget about the lag. It comes on violent and sucks you into the back seat. He still tows at least 3 times a week across Texas with at least 10,000lbs. Now, as soon a PPE (Dan please hurry) finishes the kit we will be going to the twins. Keeping the 42mag but changing the housing and adding the GT55 to the system. I don't know what to expect but after talking to Guy at So Cal its going to be scary:happy2:
Just a side note--for my customer there is not a "top" or "limit" the the streetable hp he wants. If it is scary, dangerous and just plain stupid fast he is happy

I've probably had more sets of compound turbos than just about anyone. From mild to extremely wild. As was said by Pat, you have to decide what kind of performance you want from your truck, what you will be using it for, and how much $$ your are willing to spend to get there. The only single turboed truck that I ever had other than a stock one was I put an A2000 as my first turbo change on my 02 CC/DB GMC. Didn't really see any difference in it from stock.
I Had the second set of twins ever put on a LB7 and those would push about 42 psi, and that truck ran 12.0. I currently have a nice set for sale that uses a GT4202 as the big charger. It's considered the small set for a LBZ. I had the same set up on my 07 CC that I sold and I've never had a more fun street truck. Never changed the tune, ran the samething track or tow. Ran 12.6 @107, got 21+mph on the highway, 17 around town, and 13+ towing my travel trailer. Never got hot and as smooth as silk with almost no lag. Makes about 50lbs of boost. I had my gated and tuned to run about 43lbs.
Most guys who have never had twins try and stomp on them to go. You get better and quicker results if you ease into the throttle.:thumb: Turbo whistle is also very nice if you are into that.
Again all depends on what you want from your truck. I'm obviously very biased. FWIW, the quickest dmax in the country, (Buck Spruill) is going to twins, or at least that was my last information. Buck or Jess if that is incorrect let me know.

Ive noticed this as well, why is that? Can someone please explain.
My interpretation is over fueling quenches combustion and one, no heat and two no volume accordingly. But I don't know, I saw a pulling truck that spooled for like a minute and a half and blamed it on something else like a huge charger or two.
Not trying to start a crap storm but a single stock turbo truck will run raster and get as good or better mileage - at WOT it will get hot though. Just saying to me that's not a good argument for spending a bunch of money on twins.

You start out in the small turbo's map and work your way into the large turbo's map. You aren't going to move more air than the big charger would by itself. You get the spooling characteristics of the small turbo with the top end big air of the big charger. Like I said I wasn't downing twins in general, just saying that it wasn't the best argument for them. Now Rob running 11.7 or whatever on a small set and single CP3 - OK now we're talking faster than stock.
Ken's truck would run about the same as Rob's truck, I'm pretty sure He only ran his tow tune in the 07'.
I know that, they were setup the same. Again I was simply saying that it wasn't the best argument to try to get someone to spend the money for twins when they see that stock trucks run faster than the time he listed.
That wasn't a all out tune Ken ran nor was his truck lightened in any way. It was a fully loaded truck including sun roof and leather just like he drove it around every day. A stock turbo truck at full weight wont do those numbers. Cranked up and lightened it would be just like Rob's.
