The FALLACY of A,B,A Testing REVEALED...

- A, B, A testing - That’s the only proper way to test parts, right? Listen in as Billy Godlbold explains how A, B, A testing caused the legendary Joe Mondello to use the wrong pushrods for over 20 years!
Flanked by Ben Strader from EFI University, Billy and Ben explain the pitfalls of the supposed “golden rule” of dyno testing, and both share examples and explanations of why there is a better way. Ben and Billy even go through a detailed explanation of in-cylinder combustion analysis - the comparison of Top Fuel combustion to Pro Stock combustion is mind-blowing!

Awesome video, and appreciate you all!
The sharing of Knowledge and Experience is so AWESOME!🏁
I love “Don’t let your belief dictate your vision.” This applies to life and racing greatly. It’s probably the best way to become stagnant.
One thing I have found to make that teenager get off the couch faster is to tighten up the Intake PtoV. When the intake valve is close to the valve pocket as the piston travels down the bore I feel it helps draw on the port and get the flow stared faster. I like to run my intake PtoV at no more than .050 . The mistake I see many engine builders do is they do not check the PtoV with the running springs, test springs will lie to you.
Agreed. I like to have the actual springs on for everything including degreeing and finding best pushrod length.
@@treyrags And how do you feel about my theory of running the In valve close to the piston to help draw on the port harder?
@@racerd9669 I've seen evidence to back up your theory, especially at higher RPM
Only way to fly
Excellent information. Cattledog Garage knows what he is talking about in regards to camshaft timing events and the exhaust system after all.
Of course, he has a great understanding and background.
I couldn't agree with you more. That is exactly who i thought of when they started talking about wave tuning, valve events, exhaust, etc. Adam from Cattledog Garage & Racing definitely knows his stuff, ive learned more from his videos then I have anywhere else, specially his more recent videos. Fun fact, He is also one of the few to ever be able to achive supersonic flow but he actually showed video proof of it!! Larry Widmer has claimed supersonic flow in a n/a ic engine is possable but never showed any proof. Also my understanding is that Darren Morgan isn't even sure supersonic flow in the exhaust is even possable, that alone speaks volumes to Adam's deep knowledge of the physics & dynamics surrounding engine's & Performance. Edit: I must add he achived Supersonic flow in a low compression 383sbc non race engine which is even more impressive.
Fantastic discussion!
The: Salter Racing Engines, David Vizard, Ben Alameda Racing, CattleDog Garage, Steve Dulcich, and Shane Pulido's, already know and share this knowledge. 🏁
you listed all the BS channels.
@@V8Lenny Foolish statement
@arthurking6549 Smart people dont follow them. In this video you see a guy who knows LSA doesnt matter. The guys that were listed thinks LSA is the most important thing.
@@V8LennyYuup, I had heard about some of them and watch a little bit from another, from those I've seen it wasn't exactly insightful to watch. What's really funny is how at least some of them bash some others but because they don't see their own gap in knowledge they're sometimes missing the point, which is kinda ironic. 😆
The one thing I know at least some of them has done is what's talked about in this video, they have relied too much on just empirical A-B-A testing without looking beyond that.
I'm sure they're helpful for a lot of people starting out so I certainly won't hold anything against the ones I've seen, but, there's a bit more too it all. 😄
@@V8Lennywhat is this LSA that you are talking about. My cam dr. report says lsa 110,icl 107. What does all that mean?
EXCELLENT video!
What is Ben doing in Australia ?
Awesome short video with in cylinder, intake & exhaust pressure dynamics relative to valve events with proof of supersonic flow. ruclips.net/video/tLyR976Bs1k/видео.htmlsi=d2ZKtr2YlUk5efIr
