Twin or single turbo(s) for daily driving?

tx2000gt · Jan 22, 2006

I'd sometimes take it to the track and look for low 11's or 10's, but for the most part would be a street car that I drive to work and around. Car would either be a 93 notch or 95 GT (I'm still deciding). Would drop in a DART 331 stroker, either afr 185 or 205, a custom cam from FTI, and an Edelbrock Performer RPM II intake.

Well, if you are going the dart route, and the car is DD, i wouldn't do any power adder, not because you can't, it's just not necessary. Make it a 347, possibly with a solid cam and lifters, and go NA, if done right you can go easy low 11's high 10's NA and still be completely reliable.
Add a turbo to that mix and i think you are going to add major expense, along with having reliability issues.

I agree. If a major concern is reliability, keep it N/A. Built 347 is more than enough power for the street. If you really want turbo's, twins would be better for the street.

I thought 347's had problems with wrist pins, burning oil, and not lasting very long...

The old design of the 347's did... the newer ones are much improved. Still, a 331 (IMO) is a better choice for a boosted strocker engine.

Want streetable 11's and 10's? Build a solid 331 with H/C/I and a show of nitrous

I personally went with a twin turbo setup. During the summer it's my daily driver and I've had virtually no problems with it. If you can do it yourself, it can be done for relativly cheap. It looks stock, idles stock and sounds stock. Although I love the sound of a high lift solid roller cam...it was not appealing to me for a daily driver. Another plus for me is I run premium pump fuel and still get decent gas mileage (assuming I dont get into the happy pedal to much).

As far as the original question goes...it really won't matter that much. Turbo technology has evolved to the point where the difference between singles and twins is almost gone.

Turbo's just dont seem worth the effort on a daily driven street car. A supercharger would be much more practicle for the application and a much simpler install. You cant just slap some turbo's on and go like you can a supercharger. Most of the time, cheaper to. Just my opinion though.

I built my turbo kit with the exception of the headers. I was fortunate enough to slap everything on and hit the road running. Sure I'm not reaching the full potential of my setup yet...but I bet I'm no to far off from b-splitting horsepower as it is. I would be much better off with a dyno-tune...but so would anyone who just slaps on a supercharger.

Sure superchargers are cheaper...as well as incomplete. With the extra expense from the turbo's you often also get an intercooler, fuel system upgrades and sometimes a maf to boot.

The only thing I really agree with is the ease of installation.

yea, i just prefer superchargers...different strokes for different folks i guess. I just like the nice underhood room you get with them compared to turbos. I mean for an all out race engine where getting the max power is all that counts, turbo hands down, they're just more efficent than superchargers. They harness all the wasted energy in exhaust gas. But just for a daily driver, i just cant seem to see a turb'd 302.....but like i said its just my opinion.

And your entitled to one...but I'm entitled to try to change it lol (j/k).

Really though...do you plan on poping the hood and throwing a sleepingbag under there? I can still do all the maintance I used to do without removing anything.

Oh, and as far as daily drivers and turbo's go...if you compare the number of factory turbo'd vehicles over the years to the amount of supercharged vehicles, you'll see the turbo's heavily outweigh the super's.

tx2000gt... In this particular instance it seems to be in your best interest (since you're considering a turbo) to take heed of those posts by folks who've at least installed (themselves) and run a turbo on a Mustang. To my knowledge, the only person who's posted this thread so far that has, is Millhouse.

fiveohGT · Jan 22, 2006

I've seen a turbo before. . . .it wasn't in a mustang though.

88Stangboy · Jan 22, 2006

Ive helped install turbo's on civics, a eclipse and a bunch of other rice. Never actually done one on a 5.0 though. Ive helped put on many a supercharger though...Oh well....almost to ashamed to say ive worked on rice...Got paid for it though

fiveohGT · Jan 22, 2006

now did you really get paid? or is that still shame

No, i really did get paid. For one of the civics the guy gave me $150 for helping him. Not bad if you ask me, we put on a turbo kit, injectors, intake, new valve cover and a few other things that day. Other than that i've helped my buddy andy put a Novi 1200 on his 87 5.0. And two other supercharger kits. Put on to many waste gates to even count. Dont get me wrong, i dont hate all rice. I just dislike the loud, rattle can honda's driving around with six different color fenders and ten thousand stickers all over them for parts they dont even have. To me it just shows the lack of knowledge that most guys my age have. They like cars and some even have fast cars but they pay or get everyone else to do everything for them. Pick up a book or something and learn about them, a couple of my friends dont even know how to change their own oil!....My girlfriend changes her own oil.... But then they come banging my front door down every day to get me to do something for them constantly, get some pride, i mean damn!

If you are doing it yourself, and for the ease of the plumbing, I'd say twin. But if you plan to buy a kit go single. The single kit will work just as well if not better than a twin kit.

Dag,
You know, i agree with alot of what you post, educated and informative. But in this instance, i however disagree. You don't need to have installed a turbo or have one to know that they don't make the best street cars, and if you are tough on a car, it's certainly not the way to go.
Maybe in the long run, they make more power, and definitely have a higher coolness factor, but that doesn't always translate into a great DD.

And Tx2000, you haven't mentioned any budget here, but a 331 dart, with h/c/i and a turbo kit is going to cost you well over 10,000 dollars. In fact the only way you could probably keep the engine cost below 15,000 is by building the turbo setup yourself like millhouse.

Car likely won't have a trouble cracking 600rwhp either.

Ahhh but that's crux of my post. There are LOTS of streetable, relatively maintenance free turbo cars out there these days (and I do mean lots). As with any other type of forced induction, the turbo needs to meet the requirements for the combination and application. A good place to go to gain information on these types of combinations might be http://www.turbomustangs.com/ .

The other thing that kind of struck me funny about this particular thread is the question posted by the original poster. It played out something like this in my head (paraphrased):

Question:
"I'm thinking about going turbo. Should go single or dual?"

Stangnet responses:
"Build a 347 with solid lifter cam and centrifugal supercharger!"

I had to do a double take to see if the replies I was reading were for the question that was originally asked. lol

There are a growing number of companies out there that make some REALLY nice bolt on turbo kits for Fox body Mustangs now. More than I would have imagined had I not occationally browsed the site I posted above. Let's not forget that there are many many OEM cars running turbos and that many of those turbos are in these aftermarket bolt on kits. I think that the misconception here is that if you go turbo that you have to go balls to the wall making the combination unstreetable. It's just not the case anymore. Check out the Hellion kits. You can go from mild to wild, street to strip, or anything in between and in many cases, the turbo kits are more complete than a lot of supercharger kits. By that I mean that they come with everything you need aside from the dyno time. No FMU's, or half asked fuel system boost pumps etc. but all the parts necessary for a finished install. Granted there are good and bad examples out there but today's aftermarket is capable of giving the original poster exactly what he's looking for in a street turbo system.
