Muscle Mustangs & Fast Fords Magazine

MM&FF February 2003 - Feature Article - "Hair Dryer Heaven"
    Wringing out the  the HP 5.0L turbo kit.

MM&FF March 2003 - Feature Article - "How to Cam a Wild Turbo"
    Choosing a cam for a turbo motor with the HP kit.

MM&FF April 2003 - Feature Article

MM&FF July 2003 - Feature Article - "Having a Grand Time"
    Building a 1,000 hp 327 with the HP kit.

MM&FF August 2003 - Feature Article - "Having a Grand Time - Part 2"
   
Richard Holdener and crew make over 1,000 dyno hp with a 331 and an HP race kit.

MM&FF February 2004 - Feature Article - "Inches & Pounds"
   
The crew at MM&FF build a 200-mph Mustang with the HP kit.

"We were very impressed by the torque production of the normally aspirated 408, but check out the torque production of the turbo 408.  Adding the 66mm turbo from HP Performance allowed the 408 to thump out a very Power Stroke diesel-like 650 lb-ft at just 2,500 rpm.....offering instant turbo response, as the 66mm turbo showed 6.5 psi of boost at just 2,600 rpm.  If anything, we suspect the combination may be too responsive, offering more torque than our street tires can hope to handle."  - Inches & Pounds, Muscle Mustang & Fast Fords, February 2004.

MM&FF March 2004 - Feature Article - "10-Second Stock Block"
    
This fearsome force-fed Ford Flies with a turbo.

"The trick system was necessary to supply sufficient fuel for the HP Performance turbo kit.  The single turbo kit included everything necessary to add 6-15 psi or more (depending on engine size and turbo selected) to the 302.  The engine specs hardly seem wild, yet the HP Performance turbo motor had no trouble spitting out 572 rwhp.  The torque production is where turbo motors really shine,  and this Cobra was no different as Anthony's '93 Snake pumped out an earth-shattering 708 lb-ft of torque at 15 psi......Let me tell you that from behind the wheel, the turbo motor feels every bit that fast, as the tidal wave of torque feel like you just got nailed in the back by a locomotive at full steam." - 10-Second Stock Block. Muscle Mustang & Fast Fords, March 2004.

MM&FF May 2004 - Event Article - "Fords at Phoenix"

"Anthony Dickson of Albuquerque qualified fifth in Outlaw, but his Mustang's miniscule (relatively speaking) 331ci powerplant was right in the thick of it, as he posted a trap speed of 175, which was faster than the number-one guy. Dickson would fall to eventual winner Urist in round two of competition." - MM&FF, Fords at Phoenix, May 2004.

MM&FF uly 2004 - Event Article - "Break Out" - Adams' turbo car took out Kieler and his Lincoln to bring home the glory in the Pro50.com Spring Break Shootout

"The sweet sound of a turbocharger led us to take a closer look at Glenn Adams' LX coupe.  Its low rumble is deceptive as he pounded several low 9-second times to take the class win and pocket Pro50.com's money."

".....Claiming the second position on the ladder was Glenn Adams, who drove a sedate looking red notchback quietly into the mid-9s.  An impressive elapsed time indeed, but the owner reported the car was capable of going deep into the 8s and the 155.79-mpg blast showed.  The new combination was still being sorted out that weekend.....Adams knew this round was to be his biggest test, because if he made it past Pittzer then he would have a buy run into the finals.  His longtime friend, Jack Lyons, upped the boost and told Adams to hold on tight.  The coupe unloaded a 9.11 at 145.58 mpg and he beat Pittzer to the finish line.....From the moment the green light dropped Adams was out on Kieler and he never looked back.  The notchback kept pulling away and Adams saved his best performance for last.  He ran 9.04 at 153.13 mph for the victory.... "- Michael Galimi - MM&FF, July 2004

MM&FF October 2004 - Tech Article - "Hooligan Hot Rod" by Bubba Kung - How to Build a 10-second street car for less than you might think.

"When we finished up the install, we simply had to take it around the block.  With the Hallman boost controller set at minimum.....the car produced 7 pounds of boost, and lit the tires up in first and second gears......- Bubba Kung - MM&FF, October 2004

MM&FF October 2004 - Tech Article - "Talkin' Turbos" - A review of various turbo kits on the market, including HP Performance kits.

MM&FF November 2004 - Feature Article - "Hooligan Hot Rod - Part II" by Bubba Kung

MM&FF December 2004 - Feature Article - "Boost Bash, Part 1" by Richard Holdener - Is all boost created equal? Obviously not or we wouldn't have a story.....

       

"Run at 11 psi, the turbo kit pumped out 750 hp and 679 lb-ft of torque, bettering all three of the superchargers  [Vortech, Kenne Bell and Eaton]....once the tach needle swung past 3,600 rpm, it was all turbo.  How does an extra 178 hp and 154 lb-ft. or torque sound?  While the turbos were down by as much as 100 lb-ft at 2,500 rpm, they quickly made up for lost time by eclipsing the Eaton and producing the most impressive post-4,000 rpm power curves of the bunch." - Richard Holdener - MM&FF, December 2004

MM&FF December 2004 - Feature Article - "Hooligan Hot Rod - Part III"  by Bubba Kung

MM&FF March 2005 - Feature Article - "Hooligan Hot Rod - Part 6" by Bubba Kung

"Mid-10s from a junkyard motor in an AOD GT?  No problem - just do a redneck rebuild (and an HP Performance Stage I Turbo Kit).....Here are the numbers - 10.69 at 127.47 mph with a 1.53 60-foot.....with a completely stock engine (down to the throttle body, intake, heads and block)"

MM&FF July 2006 - Feature Article - "Carolina Cobras" by Steve Baur

"With the HP Performance Stage I turbo system spooling up 9 pounds of boost, the 347ci power plant makes a safe (18 degrees total timing) yet healthy 520 rwhp and 608 rwtq."

MM&FF August 2006 - Feature Article - "Big Twins" by VInnie the Hit Man

MM&FF Magazine

"Lurking below the 301-inch modular in an HP Performance twin turbo kit with 57mm turbos.  Shoving 15 pounds of boost into the Bullitt intake manifold and Patriot Performance heads generates 602 rwhp and 615 rwtq.  Next up will be 22 pounds of boost, and, unlike his supercharged friends, all Ross has to do is turn up the boost control knob to dial in an estimated 800 rwhp.....This essentially stock-looking silver GT rolls up alongside most of its prey just like this.  A quick stab of the throttle results in a wild acoustical orgy as two turbos spool up and deplete oxygen levels nearby.  Before you even hear a blowoff valve as Ross Carter shifts into high gear, you're staring at the back end of this Mustang.  That's why we love turbocharged street Stangs.  Nothing like 'em." - Vinnie the Hit Man, MM&FF, "Big Twins", August 2006.

        Popular Hot Rodding, August 2004 - "Riders on the Storm"

"After completing a thirty mile cruise to prove the streetability of his car, Anthony Dickson blew everyone away with an 8.26 at 173.18 from his turbocharged, automatic equipped street machine." - Popular Hot Rodding, August 2004

Popular Hot Rodding, October 2005 - "Project PS!-CHOTIC Part 2"

PHR's turbo LS1 stroker motor finally cracks the 1,000 hp barrier!

"The turbo experts at HP Performance were no strangers to LS1 motors, having already produced twin-turbo systems for both the LS1-powered F-bodies....and Corvettes.....We finished off the day with 14.4 psi, where the 402 stroker LS1 pumped out an amazing 1139 hp and 1,049 lb.ft. of torque..- Popular Hot Rodding, October 2005


Hot Rod Magazine

    Hot Rod Magazine, August 2003 - Cover Feature Article - "Boost Shootout"

     A Performance Comparison of Turbos vs Superchargers.

"Given equivalent vehicles, the turbo would easily motor away from the centrifugal in an acceleration contest......The turbo offered massive midrange torque production, the only system to exceed 600 lb-ft.  Need more convincing?  At 4,000 rpm, the turbo was more than 100 lb-ft. stronger than either the Roots or centrifugal."  - Battle of the Boost, Hotrod Magazine, August 2003.

"Quad-Cam Crate Upgrade"
by Richard Holdener

"With just 4.8 psi of boost pressure, the peak power jumped from 426 hp to 530 hp, while the torque was up from 390 lb-ft to 493 lb-ft.....using the Turbo XS controller, we dialed up the boost pressure to a peak of 7.8 psi.  The minor jump in boost pressure made a significant difference in power, upping the output from 530 hp at 4.8 psi to 670 hp at 7.8 psi - the turbo system had just surpassed to power output offered by the Eaton blower at only half the boost pressure."

"The peak torque at 7.8 psi check in at 576 lb-ft.  The next step up in boost took us to 11.0 psi, where the twin-turbo 4.6-liter produced 750 hp and 679 lb-ft of torque.....The shape of the power curve did not change from the normally aspirated combination.  All we were doing was elevating the power level across the board with each increase in boost pressure.  It's amazing:  750 hp from a 281ci engine with just 11 psi."

"This '03 Cobra combination was designed by the factory for the rigors of forced induction, and with the turbos we were able to produce significantly more power at a lower boost level and a greatly reduced charge temperature."

"You may be wondering why the turbos are able to produce so much more power than the roots blower at the same boost pressure.  The answer is simple: a major portion of the difference can be attributed to the power required to drive the blower.  Since the turbo relies on exhaust energy (usually just wasted on the blower motor), there is a very small power penalty associated with driving the turbos.  From a design standpoint, the turbo is also much more efficient at processing air, especially at elevated boost levels.  These combine to give you the major difference in the power you see here."

"While we were impressed with the power output at 11 psi, we continued by upping the boost pressure to 13.6 psi where the twin-turbo engine thumped out 830 hp and 756 lb-ft of torque.  This thing just seemed to be getting happier and happier with each turn of the screw.  With our air/fuel and timing still well within safety levels (combined with the safety of 114-octane fuel), we pushed on to 16.2 psi.  Now things were getting serious, as the 4.6-liter produced 891 hp and 815 lb-ft of torque."

"Our final effort brought the boost pressure to 20.8 psi and the power to an incredible 990 hp, while the peak torque stood at 911 lb-ft.  Remember that all this is from an engine that displaces just 281 ci.  Turbos rule!"

Quad-Cam Crate Upgrade, Richard Holdener, Super Rod Magazine, November 2004.


5.0 Mustang & Super Fords Magazine

Mike Palugi's twin turbo Cobra is the fastest stock long block six speed Cobra in the country with a 9.65 @ 143 in the quarter mile, and won 5.0 Mustang Magazines "King of the Street" competition.

"GOES LIKE STINK"

"The Allens' turbo 331 crests the 600 lb-ft torque level as low as 3,400 rpm.....though capable of much more, the HP Performance turbo, from Turbocharged Power Systems, is limited to a relatively drivetrain-friendly 10 pounds of boost.  Even so, 511 hp and 622 lb-t of torque on the Dynojet have taken their toll on the car's factory T5 and rear axle.....perhaps most amazing of all, this was with no chip in the A9L processor (the HP turbo comes with a C&L mass air, matched to 42 lb/hr injectors).  And the driveability must be good, as the Allens have, at the time of writing this in September, racked up over 6,000 miles on the combo since its installation last May."

Goes Like Stink , Dale Amy, 5.0 Mustang & Super Fords, April 2005.
