2015 Mustang GT - Hellion Street Sleeper - DYNO RESULTS!!!!!

We couldn't be more excited about this Hellion Street Sleeper Kit! We have a line outside Palm Beach Dyno for this setup and it's clear as to why...it's the perfect match for these 15+ Mustangs. Clean install, killer power and many small features on this kit that separate it from the rest.
Check out the video to see why we like it some much and also check out the Dyno Tuning process and final numbers.

[@rongravel4585]

Not bad for 9lbs of boost. That oil pump being that high doesn’t cause cavitation. Ussally you need it near level with the source. It does draw uphill. But 12” above may not be the best way. I see that pump prematurely failing.

I loved this kit but when you think about all the things you need, it will cost you like 9-10,000 in total for the turbo kit and the installation. It’s a great kit, it’s just very expensive and you can get the same power for a lot cheaper.

He’s using stock airbox and I’m not sure if their tune is anything special but if you maximize your air flow and get a nice tune you can make 700-800hp with this kit very easy. Then with a built motor you can reach 1000hp. I saw a guy with a twin helion kit and he was making 1036hp to the wheels

[@PalmBeachDyno]

This car has exhaust cutouts. When you hit the clutch and lift off the gas on a stick car it's not uncommon on a setup like this to get a little extra fuel through the exhaust. And if the exhaust is hot enough you will get a flame shoot out and that pop. It will also happen if you hit the rev limiter

[@jeremyluder494]

Pita to put on a belt?! More of a pita to deal with heat from a turbo, not to mention boost leaks, boost creep, spikes, non linear power, etc. If you want straight line one dimensional speed, yeah go turbo

[@camarosaregay7943]

No ur wrong. Turbos will make more power but way more labor intensive and maintenance is a pain in the ass, it’s powered by exhaust so heat will be or could be an issue especially if it’s a top mount kit right near the motor and not a low mount kit that’s hidden and under the bottom of the car. A blower is the easiest most reliable way to make good power

[@infidel335]

Why did the owner opt for journals instead of ball bearings in the turbos?

[@PalmBeachDyno]

There really is no reason to spend that extra money in our opinion. The car spools very well as it is.

I thought it wasnt about spool speed, but rather longevity. Twin scroll kit and larger downpipes would be faster spool

[@FourValveFox]

@@jeremyluder494 BB is all about spool time. The 6266 will school 2 to 300 RPM quicker than a journal bearing. the problem with a ball bearing turbos is that when they wear open after plays pretty much the entire Turbo while the turn the bearing turbo only needs bearings

The air inlets for the turbos is at the turbos. To keep the inlets from sucking in debris and water there is L- piping that puts the intake points up higher behind motor. What I'm not clear on is the stock air box even used? I would assume so but not sure if and how combined or if there just for looks.

So it seems like a Whipple Gen 2 makes more HP on 93? You guys made 737/537 with the White 16 GT from Mustang Lifestyle on 93 and a 3.625 pulley. kzbin.info/www/bejne/jYS9foKEeZuUrZI. I'm debating between the two setups and there's no e85 where I live so I'm very interested in 93 numbers. Thanks!

[@PalmBeachDyno]

You have to consider boost level. The largest Whipple pulley makes about 2 psi more than this car did. And obviously you have to consider average hp. A Whipple will make better peak horsepower than this turbo setup due to the intake manifold and runner length. So even though the Whipple makes more peak horsepower up top, this car makes better average power across the RPM range as is reflected in the torque. 60+ ft lbs of torque in the mid range is significant. At the end of the day, you can't go wrong with either setup.
