Been waiting on the Big Bang twin turbo 454 for so long. The LS Fan Boys don't have a clue what the old school muscle will do as they think the LS has "reinvented" the wheel somehow lol. Most people don't know that there was a big bang twin turbo 454 test done back in 2014 where the junkyard bottom end 454 made 1,200hp+ and over 1,300tq+ and didn't scatter. That test needs to be ran again to show that the "dinosaur technology" still reigns supreme 😎. Cubes + boost = King. I'll bet money it'll surpass the 1,600hp that the LS ended up making on its revised Big Bang torture test.
Awesome!!!!!! I can’t wait for when you have the chance get back to the twin turbo 540 and really ramp it up! Doesn’t seem to be a lot of twin turbo big block walkthroughs or combination walkthroughs. Thank you Richard!
Hi Richard. This is a basic question but I’m having a hard time finding the answer. Where do you plum the oil pressure line to the turbos from. Some posts say use the oil pressure sensor supply some guys install an adapter between the block and the oil filter. The return is pretty easy just install a fitting in the oil pan. Thanks in advance
When will we see the big bang of that gen 6 454. Ive been dying to see it. I have been planning a twin turbo gen 6 454 for years got lots of parts but never have been able to put it all together. Want to see a big bang!
WHat are the quickest spooling turbo size / type I can run if I try to build a similar combo for a Junkyard 454, but with just forged pistons , gapped hi-tension rings, and cut-ring head gaskets for longevity. I dont want mass horsepower, just 1000 - but a quick spooling no lag boosted engine that will respond like an 800ci hot hi comp big cam NA engine..
I'm one of the only guys on the planet that know how to put a camshaft in an engine so it doesn't fall down out of the cam bearings and scratch the bearings.
How much ring gap with hyperutectic pistons with 10.5 cc domes on a .030 over 454 with big oval ports 2.19in 1.88ex 100 cc heads...rufflly 9.998-ish comp...?? Probably need more than the .28 top and .26 2nd ring gap that i set mine at??
Is 9.998 to 1 compression too much to boost if i have ring gap on hyperutectic pistons running 93 pump gas? If I slowed timing down to .... lets say 28 total at 2800-3000....is it possible?? Or do I need to run way lower comp to run 93 pump gas??
If the engine ran only one turbo to start, then phased in the second one, would the power not rocket up to 780 at 4200 RPM, With the torque leaping up to around the 1000 mark at that RPM, then stay on up there and increase hp until redline? With one turbo being in a far higher utilization zone until you could apply the scientific joke trope [then a miracle occurs] as on one comic of a demonstration of a math proof so the second turbo phased in without falling into a sort of hole, the power could be zoomed up to max far more quickly, as having twins usually gives the exhaust an easier time to escape while not doing so much work, thus less boost than the same type of turbo as a single.
In all of this turbo LS junkyard craze it’s really hard to not consider the junkyard gen 6 with twin GT45’s. Anybody know the actual weight savings going with an LM7 or LQ4 vs gen 6 454?
@Curt Curtis they definitely are bigger but if you were cool with fender dump exhaust I’d say it’s doable in most applications. I was shocked to see one fit in a 3rd gen F-body but folks pull it off 🤷🏼♂️
@Curt Curtis I would actually say the 454 isn't going to make a single HP more, since both engines can make 1000hp with twin gt45s, and will ultimately be limited by the turbos. And the ls will have a better block, 6 bolt mains, better oiling and cooling, better reluctor ignition, aluminum heads, plastic intake, etc. The BBC only seems attractive for going to displacements the LS can't and for going to hp levels with turbos that the LS reasonably can't in it's rev range, but none of that would apply to a street car.
On the junkyard 454 did you add any ring gap before boosting it? I have an LQ4 in storage for an 83 Elco I just brought! This vid has me thinking about going this route🤔 LQ4 vs Gen Vl 454?
Love these videos. With a big motor like these big blocks how do you think it would behave with twins like VS 7875s. I mean obviously if we learned anything from you if it adds boost it will make more power. But would it get laggy and benefit more from a single of that size at the same boost level?
8 psi seems to be a good limit for a GMC type blower. Pushing it up to 12 psi didn't get as much power as pushing it from 4 to 8 psi. Don't get greedy. Those last few HP get to be expensive.
The Best videos on the "tube" Richard! No unnecessary cut scenes/fancy graphics or annoying trendy background music. Just raw data and facts👌👍💪
Yeah the way it should be!
yes his videos are the BEST!
Amen to that!!!!!!

Was it on pump gas
Planning the same twins blow through on my 427 bbc. Hoping to see 4 digits. It’s going in my 92 s10. So glad you did this build thanks
the twin GT45s on that 454 thats a nice KING OF THE STREET budget build
Was actually going to request this exact episode, very cool.
As much as I Love building my LS stuff this really makes me want to start a cheap twin turbo BBC build.

any pressure source will work-there is one at the back of the block and 1 near oil filter

Get your ass in the garage and snap those parts together slap it in anything and send it.

I’d love to see that, I feel that he’d have to do rods/pistons to really send it but I don’t know much about the gen 6s
@@zachawge8576 I bet you're correct as those pistons are getting really big at this point.

I bet it's a ton. I put a real jet engine in my Mustang last spring, and the chicks really dig me.
The weight difference between an iron block aluminum head LS (~500 lbs complete) is about 200 lbs less than an all iron 454 (~700 lbs)
@Curt Curtis they definitely are bigger but if you were cool with fender dump exhaust I’d say it’s doable in most applications. I was shocked to see one fit in a 3rd gen F-body but folks pull it off 🤷🏼♂️
