Forced Induction for 5.0

[StuckInNYForever]

My 2011 GT will be coming in on June 30th. While I keep dreaming about it, a recurring dream I have is adding a Hellion or HP turbo kit to it. I am nervous because of the higher compression of the 5.0 though. While a turbo set up on the 5.0 would theoretically raise hp to over 650, I am reading that may be too much on the stock bottom end.

Does anyone have any more insight as to what will be available (and reliable) for the GT? I have been following Hellion and HP's webpage, but they don't say much (Hellion says it is coming soon).

They may end up using Methanol injection along with the Turbo or S/C setup to be able to hit the octane numbers on only 93 pump gas.

I know there has been some debate but I think with Methanol they will be able to do anything with the high compression engines..Your talking high octane numbers, low cylinder temps, and lower cylinder pressure from what I have been told by Livernois and Alternative Performance in Michigan.

Thank you for that info. Since this will be my daily commuter, I might just do the normal bolt-on route if FI gets to be complicated (I didn't want the Supercharger because I sit in bumper to bumper traffic every morning).

I'd stay away from HP Turbo kits. too many people I talk to have had issues with them. pieces missing, parts don't fit, late shipments.

You will have plenty of power from that 5.0 with bolt-ons. Steeda just released their numbers from their CAI kit and made some awesome gains. http://www.s197forum.com/forum/showthread.php?t=36248&highlight=steeda+2011

And I'm sure you've seen ARH's post on here with dyno results of their headers. 411rwhp w/out a tune.

I've heard the same, but mostly from people who have gotten their kits a few years back. I will definitely do my due diligence before purchasing such a big ticket item. This is also why I was leaning towards spending $1,500 more on the Hellion kit, even though performance should be similar! Good advice! Thanks!

I have been following the bolt on mods quite closely. C&L intakes have gotten great results, and the SCT tunes look very promising from what I have read. I saw the Headers numbers also, and I am impressed. I am waiting for throttle body numbers, as well as exhaust systems. I am going to stay away from underdrive pulleys as I have heard some questionable things with them (I'm in too much traffic to fight with them).

When all is said and done, $2500 of bolt on's should get me 75hp or so. I think that should push my traction limits nicely!

You may want to stray from that for now.

Looks promising, but I won't hold my breath!

Whipple has a kit in development, and the new GT350 has one already...not quite sure what the deal is why that kit is not available. I heard around 600hp with a whipple and 7lbs of boost, thats flywheel

I have had an HP turbo kit in my mustang since 2004. Not one real issue. I love the HP turbo kit. Gone 9.50s with a little 66 mm turbo.

But as far as the new 5.0s go and the high compersion. When I went to All Ford Nationals at Carlisle P.A I talk to the FORD SVT guys and Saleen people. and they said that it's going to be difficult putting a supercharge on the new mustangs. They said that they will probally run around 4 to 6 psi on the cars.

Your best bet if you want to have a power adder is going to be a nitrous kit. I almost think that the nitrous companies went to Ford and said we need help. Because not many people run Nitrous these days. Everyone loves Boost. But if you make the compression 11.1. It makes it diffcult to run a supercharger/turbo kit on the new 5.0s. But 11.1 will work great with Nitrous. Look what Evoultion and JPC have done with there car and a nitours setup. They are in the 10's.

don't forget Strictly Pro, they went 9s on juice and a lot of supporting mods

Thanks Dave seems like that is the mod to have for this car.

 

[Stkjock]

so far it certainly does!

Sounds like a centrifical SC will best fit for new 5.0. Centri dosnt require low comp pistons since they are not making boost under normal driving conditions.

"Due to its design and lack of low-RPM boost it is often employed on near-standard compression engines. This means that it can facilitate airflow at higher engine RPMs, when most motors tend to have poor volumetric efficiency, without substantially increasing cylinder pressures at low- to mid-RPM operation, causing knock. This principle makes this type of supercharger ideally fit for a "bolt-on" type power adder, with no modification of the pistons and/or compression ratio necessary. Since gasoline must mix with air in a fairly narrow ratio to achieve combustion, the fact that centrifugals do not add much air at low and mid-range RPM's means fuel mileage is near-stock in the cruise RPM range. They appear to be most popular with cars that have a sufficiently large engine to provide adequate acceleration from a standing start without boost, while at the same time avoiding wheelspin."

For Turbo Vs S/C, also good info on Twin Screw, Roots & Centrifical SC's. Lot to read but good info.

[Unrealford]

I wonder if Edelbrock with come out with something..Id be happy with 460 rwhp.

 

[Stangerang]

Ehh, juice, bolt ons, some suspension, and a good tire....the 5.0 is ready to cause some serious damage.

Congrats on your purchase OP!

Edit: BTW, what kind of trans are you getting with the car, auto or stick? Also, what gears?

I don't think that really says you can run a lot of boost from a centifugal supercharger on a high compression motor. While a centrifugal supercharger doesn't make a lot of boost in the low to mid RPM range, it DOES make boost pressure at the high RPM and it WILL increase your dynamic compression to the point where you will need to run race fuel or retard the heck out of the timing. Also, if you look at some of the kits (like Vortech) say for an LS1 or a bimmer, the compressors are pullied for very limited amount of boost for the very reason of high compression ratios.
Now what would be interesting is for a company like Vortech to design a compressor that provides a lot of AIRFLOW at a moderate system pressure line . . . in other words, lots of airflow, low discharge pressure, cause after all, its not the boost pressure that makes the power, its the airflow. (i.e. Edelbrock's Eforce supercharger provides airflow at a lower than typical boost level) Given that the new 5.0 motor makes great power at high rpm by way of high volumetric efficiency, this should be possible. Volumetric efficiency can be an indication of minimal airflow restrictions through the motor and therefore the ability to pass lots of air with minimal backpressure. I think we'll see a kit developed.

Thanks! I went with manual tranny and 3.55 gears. Either way I go, it looks promising!

Good stuff! I've been day dreaming about ordering one, tailoring it to my needs.....one day!
