We had just did a 5 minute test and the pressure leaked down from 75 psi to 40psi. The leak was in the fittings, not the manifold itself. NPT fittings apparently don't seal up as nicely as AN fittings.

BMC Stepping up to the challenge!


From now on all manifolds that leave the shop will be pressure tested.

Please ignore our hick voices. It is the heart that counts.

 

The shop mascot came to give us support.




Working late on a Saturday. We didn't leave the shop till 6.

Machining dummy injectors for sealing up the manifold

 

nice

 

James great stuff! Small hiccups and a quick response to fix any issues. Now that's a true business! Thumbs up

 

Just what the Honda Commuity is lacking 9/10th's of the time "Customer service!"

BMC stepping up and improving on an already worthy product. We need more of this on the daily. Happy to be one of your customers!!

 

so.....i may be dumb....but doesn't the amount of volume a certain turbo flows at a certain PSI skew this test?

IE....30psi on a 62mm verses 30 psi on a gt4272

 

Pressure is pressure, the cfm difference's of a turbo will give each a difference in its horsepower making capacity though.

 

sweet!

 

Thanks James,! Any way to seal up those leaks and test it at a sustained 125+? (or whatever your shop compressor will handle?)

 

<---impressed. Nice work.

 

Thanks for the text updates James!

 

to BMC... Stand up company. And I dont even have their stuff.

 

BMC making it work. Great customer service and you just made a future customer outta me.

 

I have never used one of these manifolds, but hope to soon. i am very impressed with the R&D to improve on a product.

 

Good stuff

Why not simulate a nitrous backfire as well? What are you trying to learn by hitting one with 125psi of sustained pressure? I would imagine it would probably warp some and if it explodes or comes apart it would be pretty dangerous for whoever is doing the test.

 

Very nice James!! Thanks for taking care of my manifold and then some without any hassle! The very best customer service I have ever delt with EVER! Im glad I stuck it out with ya.

 

I was just about to say that, pretty dangerous and plus James did a lot to make this work so I think he proved his point and no need to do anymore testing, for now at least.

 

what about heat? what temps were these at when you were testing them? wouldnt that make some difference as well?

 

Don't know if you noticed, but I also hacked off the old handmade fuel rail bracket and put on one of our new cnc ones

 

Oh badass, just keeps getting beeter

 

Oh badass, just keeps getting better

 

He's doing it in the enclosed CNC, if he keeps the doors shut, he should be fine. Personally, I'd seal it up completely, and hit it with whatever I have available in terms of air pressure and see where the weak links are. Either way, any testing is better than none, and as a current owner of one of these manifolds that has broken, the more testing the better..

 

Good ol' Haas CNC machines. We have a love/hate relationship.

 

Wouldn't the engine vibrations be a factor with the cracking issue also

 

Exactly 90 percent of the guys having issues with cracking stuff usually have solid mounts and all V band connections which equals zero flex in the whole system. Vibration has to go somewhere.
