MIXED UP BOSS: My Mistake That Lost US BIG POWER. Don't be this guy, 700HP+NOW

Unity heads back to the race engine challenge Dyno facility in Charlotte NC to find that I had made a big mistake at 3am putting the Cleveland Hi-Ram on right before the big Dyno Day!
Big shout out to Dennis my Dyno Operator for not giving up on getting Project MIXED UP BOSS over the 700hp threshold! he trimmed a bit of RTV that was overhanging inside the intake port face... Given the time on the Dyno I totally dismissed it as "Maybe" 5hp... but Dennis being ever determined felt that the power loss would be big ..I was wrong and he was 100% right!
he took the time on Easter Sunday to get MIXED UP BOSS running how it should!
I can sleep good now!
if you would like to Thank Dennis and Greg
here is the link to the GoFundMe to help out the Dyno guys in their journey to find power even when I had thrown in the towel!
I can sleep good now!!

When Andy was a boy we were working on the 1969 Boss 429 and we took the heads off some smart engineer thought it would to use O-Rings in the head for everything , So we couldn't turn the car upside down to make sure the heads went together right .A call to Holman Moody made life easier they said bo and get some silicone bathtub caulking and use it to hold the O-Rings in place . After that there was an explosion in the use of RTV and oil pickups loved it . We did too ! because we never ran out of engine work after that . Be careful not to get sloppy with that magic in a tube or " You can Pay Me Now or Pay me Later " as the old saying goes .

Great stuff, and as I have been trying to say that you are blessed to have great people who are surrounding you in the times you need them or help them doesn't matter.

That dyno competition idea I mentioned the late model pushrod 5 L engine I would bet money a lot of people would love that because right now the Fox Mustang is arguably one of the most sought-after cars for Hot Rod kids that like American muscle but too many of them are throwing LS in there thinking that the 5 L is a weak POS but most of those kids never get anywhere near 500 hp and I’ve had mine with the Paxton blower on it putting 600 to the wheels for a decade now so give these kids a reason to keep that motor because there are too many mustangs sitting in garages with an incomplete motor swap in them and if the kid just kept the 5 L they would still be driving it

With the high expense of this system, they can't make/supply a proper gasket? After all, the whole purpose of a ' dry intake' is for easy on/off for valve train inspection. So, every time it comes off time has to be spent scraping, making sure nothing falls in. ???

Past 6k RPM, the oil is getting whipped full of air. The air bubbles entrained in the oil is what causes the pressure drop.

@@Torquemonster440 I get that. The bottom line is the oil is still losing pressure and air, instead of oil is being fed to the bearings. If the rule is 10psi per 1000 rpm then it needs 70psi not 42. I see catastrophic failure in the future for a really long and expensive build.

Throw that tube of RTV into the trash. Don't use RTV on anything on a engine. Use loctite 518. It only sets between metal parts. Any excess that does squeeze out because you applied too much will be washed away by the fuel rather than leave a great blob like RTV does.
