I know this question has probably been asked a thousand times, but I'm still kinda new to Mustangs. My problem is I have two son's that are begging, and pleading with me to go with twin turbos, rather than the Procharger I had planed on. I know the cost will be at least double, and my engine internals will defiantly have to be upgraded, something I did not plan to do. So my 1st question is, how much more would I gain, and would a total engine rebuild be needed to hold it all together? 2nd, which turbo system should I look at?

 

HP makes a good TT kit. If had the money to do it over again I would've gone that route. Boost could be kept down to keep you stock block alive but the turbo's would be well out of their efficiency range at that low of a boost level. Turbo's make insane amounts of power. A turbo will make more power than a s/c will at the same boost level. But to answer your question, yes, you'll need a forged bottom end to make any kind of power. Another route you could take is a single turbo from Hellion. The Hellion kit is VERY nice.

 

Single Turbo > Twin Turbo.

 

If I were to do a twin turbo kit, I would get the MPH twin turbo kit which comes with absolutely EVERYTHING you need. Its 8500 but you can see 750+ hp at the wheels with a motor thats able to take it. Right now your power limitations will be about 425 at the wheels but thats borderline taking a chance at something failing on you. With turbos you can get a boost controler and basically throw as much or as little boost as youd like. Its expensive but if you want an all-out badass fast car, twin turbos is the way to go.

yeah, it costs some money, but it definately does the trick. And since HP's stage 1 kit comes with everythin, it should be an easy upgrade if you ever do forged internals and decide to go crazy.

 

hmm...

you ever think of Kenne bell?

if I was to instal a power adder it'd have to be a KB... but then again, I don't have the $$$ for a KB let alone a stinkin TTsetup...

 

Twin screws are definately good too, Kenne Bell or Whipple. Ford put a Roots type in the 03-04 Cobras, but when they made the 05 drift car, they used the 04 4V block and a Whipple twin screw. Whipples already developing a SC upgrade for the GT 500 as well.

 

Why not just buy a 2003 cobra and then mod that thing. Those things respond a lot better to mods than a GT. Plus a Cobra is just a better car than GT, like brakes, wheels, interior, etc...

 

ive heard a bigger single turbo does more for the car with less turbo lag then a twin turbo

 

Never thought about a single turbo, that might be an option.
As far as dumping this car and getting a Cobra, wouldn't that be nice, now all I have to do is find one for what I paid for the GT lol. The car is flawless inside and out, I'll never find a GT this nice much less a Cobra. (At least that's what I'm going to tell myself.)
What I want to do short term is, make some good HP for a GT, and then someday find a Cobra when they come down a bit. I'll probably not let the boys win this one, and go with a S/C of some kind, yes I've thought about K/B, and I read the issue in MM/FF and there was no convincing evidence that would lead me away from the Procharger, so I am still leaning that way.

 

Becuase of the fact that you can really only go low 400rwhp there is no need to do turbos in my mind unless your building the short block. Something i dont plan to do for a long *** time.

 

Isnt it crazy to have a 600+hp DD??

 

I was on the same boat but here are some things to consider. What is the car going to be used for track or street? Any turbo system will add alot of extra tubing around the engine compartment. Most need for a tubular k member to be installed. It takes alot more time to install and if plan on doing more engine work later on you have more parts to remove or if you want to sell your car. This does not apply to you but most Turbo sys require you to use their headers which is a plus if you dont have any. KB just makes more sense for a street car if you can afford it. I have a build block and will get a KB soon after. I have had a turbo car and its more involved when problems arise.

 

A 600 HP DD isn't crazy, is it?

 

Its not crazy but you need some DP.

 

Look. If you plan on getting a built motor. Single turbo is the way to go. Just get a big *** turbo and you will make more power then 2 small twin turbo's and less turbo lag. My friend has a rx7 and ditched though's small *** twin turbo's and got 1 Single turbo and that car is insane..

 

Venom,
Without sounding to stupid, what is DP?

 

Delicious Pretzels

 

Deep pockets as you have to upgrade alot of things to be safe and ensure you dont break down.

 

If your A/F and timing is tuned near perfect....you can run around on 20psi and 600hp all day long with out having problems....thats IF it is tuned properly. You can do it on a stock engine also. I know some of you will argue that you will have to build the engine to hold the power, you dont have to completely build it up to hold it just needs good tuning and slowly increase the boost with adding fuel and timing. My buddy and i have been tuning on mainly imports for awhile and 90% turbo and just getting into doing the domestics, but we've learned from other tuners what a stock engine can handle...altho the clutch and tranny might not handle it but the engine will.

 

Thanx everyone, I knew I would get a lot of different opinions on this subject, but I had no idea it would be this wide of a range. 20 lbs boost is something I thought could not be done, safely. I don't have to rebuild the guts of this thing, that's another thing that has me intrigued. Does that go for S/C boost also? I'm not gifted with DP, but I do have some extra coin to have some fun with. Now, I just have to figure out where to place that extra coin to have as much fun as my money can buy. I am slowly finding out how much fun these Mustangs can be to build up. I didn't have the INTERNET back when I had the old big horse HEMI, so this is really cool, the help I get from you guys is great, and I appreciate all of it.
to you all!!!

 

Ok check this out, i went from a procharger @ 11psi to a TT setup on my v6.

My procharger made 309whp/313wtq @ 11psi

On the exact same setup the only diffrent being the turbo kit i dynoed 305whp/354wtq @ 8.8psi so with 2.2 less PSI i made the same HP and 50 more tq. . not to bad huh?

check out the dynographs of the two.

this is my dynograph with my TT kit at 8.8psi 11psi and 15psi

This is my dynograph with my 11psi procharger

I love my procharger kit. 10psi, motor doesnt need to be built.. yet.

Turbo setup is good for someone with money, or trying to make a sick track car.

Id go with a s/c for money and use reasons. Its going to be hard to control 700whp on street tires.
