All BMC Stage 2/3 Manifolds are undergoing a fabrication process change to insure greater reliability. Anyone who would like this upgrade feel free to send me your intake and I will cover it and ship back 100% free of charge.

We stand behind our product 100% and will take care of our people!

 

Great company to stand by the product - very rare anymore.

 

Thats why I run his product on my race car.. Very good people and can't say enough about them....

 

hell yea James! good to see ya helping people out...

 

good job james..


Hope to run one of these on my NA car soon..

 

Stand up company right there!!!

Now if we can get a tranny company to stand behind there products the same

 

Now thats service.

 

 

Just saw this thread, obviously need to send mine in.. Are you supplying shipping labels as well?

 

dont own a bmc but damn good service

 

I have had issues with mine and just like James said he took care of it proptly!
Has anyone ran an 8sec pass on this one other than chris?

 

Where did his break?

 

Same place mine spilt on 40+psi rear top weld. James put some reenforcment and haven't had any issues.

 

Mine split at 30 psi on the bottom rear weld, on the dyno at 10pm on Friday before Vegas..

 

Thumbs up to James, always backing up his products.

 

Quick fix from scrap aluminum to go racing.. Thanks to Joey from Full-Race for the midnight welding!

 

Unfortunately no I do not supply the shipping label for package to me, I will cover all shipping back though.

 

maybe its that run of the litter but ours has been beat to **** and still works great. the dam thing was in a fire, crashed, took apart over a dozen times, dropped ect. still works good, just doesnt look as pretty lol

bmc

 

i can see why locash's failed

 

Are they getting a bevel before welding?

 

Will post up pics in just a little bit of the new, bullet proofed plenums.

 

Parks, yours was welded from the inside as well, mine wasnt.

The more I think about it, its cheaper for me to just fix it myself and run it, than pay to send it back and wait. Its not like I am getting reimbursed for my time anyway.

Wait, a "bullet-proof" plenum? Can I just have you send me a new plenum and a UPS label and I'll send you this one back for you to dispose of? I'm really trying to avoid a lot more downtime, as I dont get a lot of opportunities to race as it is..

 

Well it took alot of new fixturing, and special tooling to be made to do this. All Stage 2/3 Plenums will be welded on the inside the plenum now. This should completely cure the cracking plenum issue we have had.

Penetration pictures before the inside is fully welded:




And now for the real fix:




BMC Stepping up to the challenge



Very sorry for anyone who has suffered from one of my earlier manifolds, I am very sorry.
This issue should now cease to exist!

 

Oh Parks, if you havent already noticed, they leak at the runners as well, ditch the o-rings and weld it up, or have James do it for you when it goes back for improvement.

 

The only previous welding on the inside was done at the Sideplate to the Baseplate. I have just recently developed the tooling and fixturing required to weld the plenum cap to the sideplates on the inside.

Also I will no longer be doing the modular design (big port) due to the runner leaking issue.
It has proven to be a bit unreliable and I can't have unreliable products out and about.
