Exhuast testing Round 2 - HKS vs Buschur
Here we go again, more R & D and testing here at Dyno Flash and The Shop
We had a chance to test a HKS exhuast vs a Buschur Exhaust - its a new hobby of mine to test various exhausts
Today's test was a IX Evo
Mods
Greddy Profec B II EBC
Walbro Pump
HKS Carbon / TI cat back
Megan Resonated Test Pipe
Unkown full 3" down pipe
93 octane - 21 psi peak boost - car was very knock happy - timing was conservative
We tested this against the Buschur full 3 " Bullet V Band exhaust system
I was suprized not to see more power from the Buschur vs. the HKS - but the tale of the tape showed between 3 - 9 whp gains
Lets face it HKS is a premium product and they do great R & D and their product worked very well
The Buschur system - full 3" T/B did weigh exactly 20 lbs less than the HKS system and it costs less as a complete syetem (non V band version) shipped than just the HKS cat back
Note - I have scaled the dynbo sheet to zoom in on the gains and losses
This is how we test the exhuast weights
Side by side

Still the 3- 9 whp gains through most of the power band were a healthy increase considering we are testing one performance unit vs another
HKS is obviously very good
Buschur was better
Obviously on a more powerful car the gains may have been greater - (we may test that soon)

That is Jimmy - owner of The Shop - www.theshopct.com
He is a really nice guy and I appreciate his kindness to tolerate my new hobby which ties up lifts and wastes dyno time

For better control, using the same exact test pipe would have been optimal. Although, we can't complain because YOU are doing all the work. The community applauds you

Me either, but I always appreciate a business who is willing to allow me latitude to do R & D and testing
Especially at the end of the day most guys want to go home
I love being part of a team that stays there as long as it takes to do what ever we need to do just becuse we like doing it
