Yeah no $hit!!

Hal /\ on the plenum strap!

 

No, they were not available at that time. We have one on it now, and should be at the track in a couple weeks. The CF endcaps are very thick and seem rather strong. In the event of a nitrous backfire (or meth, etc) something has to give. The easiest protection I can come up with for backfires is some form of large freeze plugs that can handle 100psi. Those would work fine under boost, but for extreme pressures they will pop out rather than grenade manifolds, bend throttle plates, etc.

 

 

Can you please elaborate on why you're not using the Cosworth plenum? I'm befuddled...

 

Ha ha - still learning a lot, I assure you. I am working on a few things though .

Med school is a distant memory (gladly forgotten) and I can't complain about the cash flow the day job provides.

 

Weren't people experiencing boost leak from the sides?

 

Back to the original topic.... Eagle, did you every have your car dyno'd with the stock plenum and current setup???

 

Hal, can a freeze plug be installed on an intake manifold (i've heard of them being installed on an engine block)? Any type of pressure release valve may be a nice safety to have in place - of course there'd be a fireball that comes out the end of it...

 

I am not using it becuase it leaked. I had Cosworth inspect and pressure test it (30psi) they said thya fixed it and it didn't leak. Well it did I hand delevierd it to them and told them I wanted my $$$$ back or else. Well I agreed to a brand new one with a 100% GUARANTEE it is pressure tested with meth. I am having talks with them about making a custom aluminum or some type of metal side covers and totally getting away with the O ring and just use a gasket. This will be done just to keep me happy cuz I am ready to flame on them. IMO the Cosworth plenum is a big Failier (as far as structure) Who uses a rubber O ring gasket??? Knowing people are going to be spraying nitrous and meth??? But what do I know??

To this date I am the only one spraying meth thru the Cosworth, and to this date its not holding.

As far as this freeze plug to talk of??? Tell me some more and how it works???

 

my god, ive never seen that before! at least you could limp it home...wow!

 

Like the freeze plugs in the engine block, basically if the coolant froze (running straight water), the plugs would pop out because of the expansion and in theory save the block from cracking...

You could have something like this fabbed up on the stock plenum, or any aluminum one like the crawford. Have a freeze plug press fit so that it is airtight to whatever PSI you will be running plus some extra for a margin of safety, but if a backfire occurs which would increase plenum pressure dramatically, the plug would pop out relieving pressure and saving your plenum/engine.

 

Like an O-**** Plug!!!!

 

I was wondering about a 1/4" or 1/2" pressure relief valve in the range of 80 psi... This way you could misfire multiple times and keep on going - ha! When you see flames spread across the windshield, you'll know to stop hitting the rev limiter - lol.

 

I will talk to Joe the "Mad Man"Kenefic and see what he thinks? We might have to do this. Plenums and hood would get a bit costly in time .


I'll tell you what these turbos LOVE high boost!!

 

BEWARE...I think Raj is a closet pyro. Have you been skipping your counseling sessions j/k

 

Just make sure they are not aimed at anything critical, or weld a little cage around them

 

What kind of boost controller are you running? Also, do you use the FCON's launch control?

 

I sent Wilson a e mail about possibly making me a mini catchers mit!

 

wilson sells individual burst panels.
