- CAN YOU MAKE MORE POWER WITH LOWER BOOST? HOW MUCH BOOST CAN I RUN ON A JUNKYARD BBC 454? HOW MUCH POWER DOES AN INTERCOOLER ADD TO A SUPERCHARGED 454? CAN I RUN BOOST WITH STOCK GEN 6 454 HEADS? WILL A CAM HELP MY SUPERCHARGED BBC? HOW MUCH POWER DOES A TUNNEL RAM ADD? DOES A TUNNEL RAM MAKE MORE POWER THAN A SINGLE PLANE INTAKE? HOW MUCH BETTER IS A 496 THAN A 454? WHAT HAPPENS WHEN YOU INCREASE THE DISPLACEMENT AND POWER ON YOUR SUPERCHARGED BBC? CHECK OUT THIS COMPARISON BETWEEN A SUPERCHARGED JUNKYARD 454 AND AN AFR-HEADED (PERFORMANCE BUILT) 496.
Where’s the big boost 3800 video?
Love this engine set up . Especially the 496
The take away is always the same. Rich knows what he's talking about and proves it out on the dyno. Your work is much appreciated 👍
I appreciate that! but obviously I also make mistakes
I think the 489/496 combo is a killer bang-for-the-buck setup on the street. With a little more compression (say 9 or 10 to 1) and E85, you could easily make 1,000 hp+ with 7-9 pounds of boost. It would probably run forever too.
everything is better with "Techno" and Boost. thank you for bringing it back.
I am still impressed at how well a stock 6.2 LS stacks up against a stock Gen V or Gen VI BBC..
Darn I would have loved to see how it went with tunnel ram
How would you run a blower with a tunnelram? Would you use two blowers/turbos with blow through carb hats; or two throttle bodies on a big plenum employing EFI (kind of like on the Hell Cat only going up through the hood instead of using an old school cross ram)?
Hey Mr holdner do you still have those cross ram LS intakes? I'd love too see what the power numbers specifically the low end power numbers on a 4.8/5.3 with the truck Norris, I'd love to see the aftermarket and more people use them they're a very interesting manifold style to say none the less, those long intake runners could be a saving grace for 4.8 owners
too much trouble for daily driver
Hey Richard... a while back I made a comment about a big block chevy motor I got from the junk yard... it was out of a propane delivery truck... I said it was a 502 and everyone said it wasn't... it was a mark 5 tall deck 502 they put them in Kodiak 6500 mid 90s heavy work trucks... the block numbers even identified it as a 502... can you look into finding one and boost it please 🙏
Thanks for sharing
Big inch motor plus boost equals good times. I need to find something cheap to slam a blown big block in!
496 with tunnel ram and supercharger would be epic
We need to see Big Bang ameribarra
When are we going to see a 3800 pushed until it fails. I would love to see how much power you could make from one!
Twin blower on a tunnel ram would be bad ass
I wish I could find Richie a radial Wasp or Liberty V12 to strap on the dyno. That falls under the other guys right?
yes it does
Maybe a packard 2500? Lol probably more than the dyno at westec could hold.
Hey brother I was hoping you could help me with a question if I put an air fuel sensor in the cross pipe that connects my two exhaust pipes together on the H pipe of my Mustang will I get an accurate reading
no
What if the 496 compression ratio of 8 to 1 was raised to 10 to 1, so more power normally aspirated. Would the final boost pressure be even less than the 8 to 1 run? Where is the sweet spot on compression ratio vs boost/timing on pump gas?
raising compression raises boost too
@@richardholdener1727 Gotcha, Thank you…
Hi Richard, Always wanted to see 2 centrifical superchargers with a 496 tunnel ram blow through carb setup? What do you think?
I have twin TorqStorm blowers coming up
@@richardholdener1727 is that going to be on a tunnel ram, because my question is do you need pre carb cross pipe to balance boost pressure or is it possible that the tunnel ram can do that for you post carb? Thanks
@@donwalsh7521 ...or it has one of those dopey looking pressure boxes on a single carb. yuk. I guess the pressure would over-ride any fuel flow issues with single carb on T.Ram. Im interested to see !
It will take about 21 pounds off boost to get 1000 hp from a 454. So e85 is the way to go. And its cheaper then gasoline. It will take more fuel per gallon but think of all the advantages. No intercooler, great, very little turbo lag. With expensive heads the power numbers won't jump dramatically. Not worth the money either.

Hey sir. Doing a budget build stock l86 to lt4 supercharger and wanted to keep stock injectors and fuel pump if possible. Planning to install stage 1 or 2 blower cam with springs etc. Will the stock fuel system work? Thx in advance
stock lt4 injectors and pump
@@richardholdener1727 OK so upgrading to lt4 fuel system is necessary? Just confirming b4 having to spend the extra money. Lol
I would have liked to see a more apples to apples comparison. Same heads. Same cam. Same induction. But different stroke.
that was not the test
You just would have seen a very similar power curve.. with the bigger motor getting to the higher numbers 200-600 rpm sooner because of the increased displacement.
Test a supercharged 3.8L built as big as you can get it with nitro methane .. alcohol and a150 shot NOS. LMAO
Fack bbc 😎😎😎😎😎awesome
Personally I blame squirrels
