Killer B Motorsport Header Testing Results
Event: Killer B Header Test & Comparison
Location: Epic Motorsports, Fayetteville, NC Ambient Temp: 70s Elevation: Sea Level Weather: Partly Sunny 08 Sti Tuner: Robbie/ Epic Motorsports Dyno Info: Mustang Peak HP at RPM: 295@5,300 Peak Torque at RPM: 339@3,500 Baseline hp/tq for a stock on same dyno: 241hp & 247ft/lbs W/ Megan Cat-Back Target Boost: Target AFR: Fuel: 93 Here's the end of the day results with the car as it came in the morning, stock with the exception of a Megan Cat-Back, and as it left at the end of the day. The Customer was VERY happy with the results. Before converting the car to stage II we installed the Killer B header just to see what kind of results we'd get on essentially a stock car. The OEM tune was not very happy with the changes so we could only compare both stock vs. Killer B header using the Cobb OTS Stage I map. Thankfully, we had tried out the Cobb Stage I map after getting our baseline runs. Here's a comparison of Stage II with OEM header vs. Killer B Header OTS Stage II with OEM Header vs OTS Stage II with Killer B Motorsport Header. Stage II mods: Cobb AP Stage II, Megan Catt-Back, Invidia Catted DP, K&N Typhoon Intake, Walbro Fuel Pump, and Killer B Motorsport Header/up-pipe. +25 HP and +18 ft/lbs Here's the Cobb Stage II vs the final Epic Motorsports Custom Tune.

100% for real, your saying that OTS stage 2 OEM header VS. your header had that much gain? was any tuning done or was it just thrown on and run again

Notice that on the stage 2 testing with the Cobb OTS map, the test with the headers is a lot leaner than the test without. I would easily attribute at least a decent chunk of that gain to the fact that the headers leaned out the tune.

very true. looks a little to rich before hand though. looks pretty good after the header right around 11.

What's the point of comparing to stock? I want to check the difference between this header compared to other named brand header's! That will be the real test!

the fact that's it's 321 stainless steel is enough to sway me (everything else for stock location seems to be 304) but i'd like an option for an EWG on the uppipe.
nice results and nice product. good to see someone designing something with quality materials |

I have a few other comparisons, but in general with the longer primary type headers and 1.5 scroll headers (Invidia, GP Moto, etc.) you see significantly reduced spool time and power carried higher into the revs. With the shorter and smaller diameter primary type headers (Perrin, GTSpec, etc.) you'll see similar or better spool time with decent gains higher in the revs.
Here's a comparison to Perrin's headers (Killer B setup dashed lines)... |

I just took it out for a spin with this header and new 20g installed and feels a lot better then the stock mainfold throttle is dead on so responsive now, I also had perrin headers before and the response time wasnt half as good as these headers
mind you i didnt hit any boost really not tuned yet for the new stuff cant wait to re-tune |

For which plots EFI or Epic? I know the Epic before/after plots use the Cobb OTS maps, except for the final custom tune.

BTW, I'm not saying your product is not good, but we all have to be very careful about how we run tests like this to make sure they're fair. I don't want this to turn into another Garage GT fiasco . Thanks -- Ed Last edited by Equilibrium Tuning; 11-07-2010 at 06:46 PM. |

My opinion would be that Chris built himself a good working header. I wouldn't mind swapping out my Tomie and trying the KillerB out on my XT |

I don't know... I haven't tuned too many perrin header VF cars that had a torque peak near 4500RPM. I've also seen a lot of perrin headers leak from the slips or warped flanges, so I wouldn't be surprised at all if that's what caused the excessive lag.
The only real fair comparison I see here is the one done by EFI. It shows some healthy gains above 5k RPM with a bit of added lag compared to a factory header. Now I'd really like to see a fair comparison with a Tomei/GTSpec/MadDad header. -- Ed |

We will also soon have some test data for the Killer B header on one of our shop cars (08 STi with a 20G) . Wanted to get something done yesterday but were derailed when our baseline testing was corrupted by a boost leak. Since the only thing worse than no data is bad data, we'll have some fair and objective data up on a week or so.

We did all of our testing in one day which made for a bunch of back and forth parts swapping. But We have a car that will be tested in a similar fashion as efi's. The car will be tuned with a factory manifold then the Killer B header will be installed and do a few more pulls. |
