So is the best idea just to use nitrious for the time being and go to a 5.0 when I have the cash. It's funny the kits that make these cars fast are over $5000 but to replace the whole engine it's half that. I already have my care doing 0-60 in less than 5 secs and I fairly happy with the power personally I feel like a mid 500 horsepower car is quite perfect for having a lot of fun. Now days people want as much power a possible and that's just crazy to me I'm not super impressed with how fast your car goes in a straight line I'm More into how fast you can go at the track.

I went to Las Vegas and raced at the track you could drive any car you wanted and the car I had the most fun in was the 6 cylinder twin turbo GTR. I'm wishing now I just looked harder for a car and maybe bought the GT but with my driving record I don't think I could afford it. Insurance wise.

If your reason to turbo your mustang is based on the GTR I feel like you will be sorely disappointed even if you went with a 5.0.

The GTR is in supercar territory and is one of the best handling cars in the world. You are setting the bar pretty high on that one.

That is entirely dependent on the type of racing you do. There are potential classing advantages to NOT using the 5.0 in both time trial and American Iron. In TT, you start a full base class lower, and have a lower minimum weight to work with. In AI, you have a way lower minimum weight, or you can go forced induction, and still have a lower minimum weight, and a more capable car in the corners...
Speaking of - I would love to get into autocross. Is the 3.7 mustang relatively competitive? I feel like it very well could be if you are smart about mods and dont bump yourself out of a class.

No what I was trying to say is I had a lot of fun racing around a race track. Going in a straight line is fun but racing in auto cross or any type of racing that challenges the driver and not just the car is what I looking for. The racing experience just really got ,e into the mindset. Trust me I know that the GTR track pack is the only 3400 pound car that can handle and inspire confidence like it does on the track.

Are you suggesting that your not 100% happy with your procharger setup? I was thinking eventually getting procharged, but so many people have sold theirs and moved onto 5.0s or better performing cars.

no that's not what i'm saying at all, i love my procharger, i'm just saying that the 3.7 platform isnt the most sought after thing to build. And in my personal opinion if your trying to build a fast car it would be easier to go another direction. anything can be fast if you throw enough money at it though.

Like he said-"

There are a few 3.7 V6 Turbo Mustangs running around Florida that are turning in the ten second range and still drive like a normal car and still get around 23 to 25 MPG combined.
All it takes is $$$$$ and you can have the fast Mustang of your dreams.
I read someplace that a 2015 turbo four was running in the elevens. I don't know how streetable it is but "ELEVENS?" I don't know what mods it has but 11's? "Wow"

A platform is not limited by how much power its engine can make, its limited by how much support it has.

Making 1000 whp is not as simple as a strong motor and a lot of boost, its a very, very, very, complex culmination of parts, tuning, experience, and things many people dont consider. I believe what 2011FastFord is getting at is that you're going to spend a TON of money on building this car, and only have 500-600 whp to show for it.

This is not simply because no one has done it, but because it is incredibly difficult, time consuming, and expensive to pioneer these things, like creating fueling maps for different injectors, getting fuel pump voltages and demands from a dual pump-return style system, scalaing the maf, or replacing it when the current 3.5" gets pegged ... There is a LOT more to this process than just strong motor and big boost.

Personally, i have been involved with a platform that had 0 outside support, anything and everything we did was a result of tuners working on the forums, and collaborating with one another, and we single handedly paved the way for our platform with years and years of hard work and money, and it sucked ... it sucked to just not have a straight, clear cut answer to questions, it sucked to not have off the shelf parts when we ran into a limitation. The shops put their money into the 5.0 because thats where the money is, and the 3.7 gets put on the back burner. If a stock motor will survive to ~500 whp, it makes no sense to do a build for ~550 ... just my .02.

Plus, built motors start having some issues of their own; the looser piston ring gaps can lead to smoking and consuming oil, but you need the looser gaps to handle the heat and expansion under boost. Theres just as many new headaches that come from a built motor as you may feel are being solved. I'd say enjoy what you have and call it a day.

This is true but from the very limited research I've done Forged 4032 pistons seem to be the best compromise in a daily driver. Sure it may not be as strong as the 2168 pistons but they seem to be able to hold anything a 3.7 could reasonably throw at it.

I wish someone with a firm financial backing would build a proper 3.7 mustang to show what this platform is capable of. Though that is asking alot because if someone had enough money to throw it into a 1000 hp 3.7 then they had enough money to start with the 5.0 in the first place.

It is disheartening that none of the big shops seem to give the 3.7 any credit when it is an amazing engine at the end of the day.

What's your definition of a proper 3.7?
Because there are 2 cars running around with built motors. One that'll be up and running and twin turbo'd next month. And 2 rumored to be done before may.

Just slapping Pistons and rods in a motor, a racecar does not make. I am not trying to discredit the 3.7, but there is far more to the 5.0s making big power than just two extra cylinders. Not saying the 3.7 never can, or will be there, but that it'll be difficult if a privateer Is the one to do it.

Proper as in ported heads, ported intakes, cams, possibly lower compression pistons (though I'm still not sure if that matters too much with Ti-vct). The same way shops pour big money into 5.0s.

I've seen builds in progress and I'm patiently waiting to see how they turn out.

well in that case, you've got one on the way.

as a road racer, I'm sure you can understand the benefits of a lighter, better weight distributed car. and judging by SSM's review of the 3.7. it's actually capable of higher revs. The market is there for the 3.7, it's just scattered.

I can't wait :dance:
lol, it's not me :p
but you can expect to see him soon.

I'm sure it is capable of higher revs, but will the IM support it? Will it support enough boost through a 2 piece plastic intake? Does someone have a fuel map for enough injector? Does the block have any physical limitations like the 5.0? That's my point, this argument is not about the 3.7 in particular, it's about any car shooting for big power with little support.

I agree, building a car with no aftermarket support would suck. But, I would argue that the 3.7 has a decent aftermarket, just need to know where to look.
I'm going to take a stab at trying to address some of those issues, but relate em to the 3.7.
Several have created their own sheet metal intajes, however, none have been offered at this time to the public (only by special request). The cylinder walls are considered the weak link, however there is a company currently working on the sleeves. Two individual parties are working on developing (or have developed) return style fuel systems.
the aftermarket is there, it's just scattered. You can't order everything you want from one place.

I haven't been keeping up much with the 3.7, but hell... Sounds like it's further along than I was giving it credit for.

Hey guys....great thread. I am installing a procharger on my 3.7 with 45k miles after I maxed out on power with NA. I have full stock internals though...I am having the procharger installed by a great shop here in Southern CA and it will be dyno tuned...he has done many supercharger tunings but not on a cyclone.

Looking to run 8psi-9psi boost (as procharger sets for stock) using a 3.70 pulley (to makeup for lost boost with my ported intakes...).

My question is, can the cyclone internals handle this ? Can this motor handle a procharger safely ?

Any advice is greatly appreciated...

There are more then many on these forums that just threw on a procharge on a 3.7 V6

I don't think your going to have a problem. Just put it on and enjoy the power. The 3.7 already has a forged crank and forged rods along with oil cooled pistons. Unless your going to be racing it every weekend and flogging the car every single day there will be no problem.

Yes, you'll be fine
Just make sure someone experienced with the 3.7 tunes it
