D414 intake manifold

Recommended Posts

I'm sure I dont have anything to worry about, but I watched a video of a John Deere 4430 intake manifold blow up while making about 70psi of boost. I have a 966 with a DT414 (originally D414, then overhauled and built into a DT414) that will make about 40psi on a good day at the track. I'm pretty far from 70+psi but I was curious how much pressure the stock intake manifold can hold.

No problem with the manifold.  I run north of 70 PPSI of boost with no problem with stock manifold.   .

Good to know.  I've only got a 10mm pump and S2e, but I'm sure I won't even have to worry about that even after an S300 and 13mm pump lol

I would recommend making a clamp for the rubber boot that bolts to the intake manifold.  For your information I am running a 3X4  turbo with p pump.  max boost is in low 100's

X2.

I'd do it at the turbo too.  Scares the tar out of you when you blow the pipe off.

I would recommend using a V clap on the turbo end.
