Dangers of fuel Enrichment

[Todd....!!]

WOW Bill,

That woulda been cool to see, from a VERY FAR DISTANCE!

I have pity on the dude, he IS runnin a HEMI however, so he doesn't need
too much pity, except when we see him at the pumps, EVERY PUMP, on the
way to wherever he's cruisin tooooo.... lol...

But really, he should have some sorta popoff valve to prevent this from
happenin...  Ya know?

Seeing that just about ALL race carbs don't have power valves, I'm sure
he didn't blow any of his in that fireworks event... ya know?

Isn't this one of the reasons popoff valves were invented in the first
place?  To prevent things such as what happened to him?

Tell him about em, see if he knows what they are?  Maybe he just didn't
wanna mess up his Roaster, well, NOW look at it, pieces everywhere...

Also, ya never DID mention whether or not he gained or lost performance
between the two intakes... Did ya get a clue from him as to this or did
the explodin rat roaster take over the conversation...

Hope to find out which intake is better...

ALSO, within the rat roaster itself a lot of the racers play around with
puttin dams and ducts in all different sorts of areas in order to
increase/change flow characteristics within the manifold...(A type of
tuning it to their application, ya know?)

Some people claim gains of up to and over 40-50 HP just from the use of
a Rat roaster type intake!

Most racers usin the roaster, stock lookin cast or handmade sheetmetal
will tell you and even show you just about EVERY aspect of their engine,
EXCEPT for the internals of their roaster!!  That's where the secrets
are hidden!  Can't IMIAGINE what the heck they're doin inside of theose
things that could be so helpful that they think they'd lose their 'edge'
if they show someone the internals of their personal roaster setup...

A port injection system would look really cool atop a roaster on a
hemi...

Where would the fuel rails go, would have to be really high in the bay
if placed on top of the intake....  also, since the ports are within the
inner bay of the roaster, how would the injectors be placed?  The
roasters bottom section is bolted straight down onto the heads, the top
must be removed in order for this to be done, wheras the top portion
then bolts to the bottom portion of the roaster....

Thanks for the warning about em, I DO beleive a popoff valve would've
allowed him to still be runnin that roaster, what do ya think?

Later!

Todd....
