so what is the deal with the masks
Jon kasse built a N/A 598 BBF that laid down 1108hp/933tq on the dyno ??
https://youtu.be/dIrvPfrnXjM?si=tNN8rp9fAVefMxVC
we were makin 1000 hp in 00 with 505 inche std deck holley blue pump and single flowed dominator…would run 8.80s ….them mask will def kill some hp as well
Ugh, the super high boost and HP import guys almost all use mechanical fuel pumps….
They look so dumb wearing those masks lol
Why is there a sock over his face?..
Masks off…… the "experts" said they didn't do anything shortly after the election… oh wait it's an election year coming up! Put em back on!
Am I crazy? Since when does gaining hp while adding SERIOUS area under the curve equal a fail? That tunnel ram is a HUGE improvement everywhere except the last 200 RPM. Suck it up, shift 200 RPM lower, and enjoy a far superior power curve.
THEN you act like it’s all sunshine and lollipops because the headers win back 100 of those 200 lost RPM. Really? From total disaster to drag strip dominance in 100 RPM?
You guys put out some of the best engine info available, but this is definitely not it. If your goal is going quicker and not some arbitrary goal like “I wanna shift at X RPM!”, the tunnel ram is the undisputed winner here.
Agreed on simple and tall intake
Whoever said you can't make a thousand HP with a Mechanical pump is an idiot….
Can anyone explain why theyre masked up when installing the tunnel ram?
Thing should make almost 1200 with the SR style heads, monster solid roller and almost 15:1 compression.
Not impressed.
I'd tig weld a couple of China walls together a d to the block, on each end and only use the 1 China wall gasket's.gaskets. or if you have access to a cnc machine make the the right hight from the start and then tig weld them to the block.
Fuel pump seems like more than enough at 120 gph. That is 720 lb/hr. The efficiency of the engine is probably between 0.4 and 0.5 lb per hp per hour….1000 hp needs 400 to 500 lb per hour, so 67-83 gallons per hour. Roughly. I guess it would be nice to have a big cushion.
I was wondering about the masks, too. That type will do absolutely zero for fuel vapors, carbon monoxide, etc. Literally zero point zero. Which is only a little worse than what they did for covid. Great to stop small parts getting in your mouth, though!
Somebody keeps commenting "trigger " and "boomer" over and over. Occasionally with other words and/or "lol"…
Weird…
So jealous! Wish I had a spare 18 k for a short block. Just gear it for the curve you have. Let that torque work…..
I only clicked on this because I wanted to learn what a tunnel ramp is.
Face diapers in dyno room …AND NOT WHEN DISCUSSING THE RESULTS!?%#????
So did mechanical fp work?
7:40 Black line is the tunnel ram right? Give up 250 RPM at the top to gain that much area under the curve? Even on the 1-2 shift, 7250 down to 5000, 20-50hp advantage until 6750. Shifting at 7500 (versus 7250) is only going to raise where you catch 2nd by 150RPM. Of course each gear after that gets you further into the meat– that tunnel ram is dramatically faster than baseline on the street and at the track.
Gotta love compression. My 455 Olds likes its 13.78:1 flat tops zero deck and 64cc chambers
In my opinion a header pan evacuation system does add power, they certainly help with ring seal. First time i tried this system it was shocking to pull a breather off at an 1100 rpm idle and stick it to your hand…the vacuum stuck so hard you had to twist the breather to get to come loose from my palm. Didnt think it would have pulled that much vac
Can you get 1000HP with a mechanical fuel pump and tunnel RAM ?
There fixed it for you lol, btw y’all are awesome.
Why the masks?
Race pumps race pump will support a 1000hp
If MotorTrend replied, I would love to know the fuel being used… but we know they don't reply anymore, so oh well
Area under the curve wins every time
Whats this tunnel ramp thing in title ????????????????????????!
My only question is, why are you wearing a mask in the dyno cell but not in the controll room.
Enginemasters is the most interesting series.
tunnel ramp?
Whats those face rags for?
Man I was hoping they put the 4 barrel on again
Is that a blower on top of a tunnel in the back??
