LOW $ JUNKYARD 4.8L TURBO-ALL THE BOOST!! 1200-HP, BIG BANG 4.8L

TURBO LS, SBE 4.8L, boosted with Cheap E-BAY turbos, til it breaks! Behind the scenes of The original Big Bang LS Project. How much power will a stock (Gen 3) bottom end take? What worked. What didn't! What would I change to do it better? Can an SBE 4.8L make even more power with better prep, turbos and intercooler?

[@UncleTonysGarage]

Dude, seriously...you've got the best gearhead channel on the Tube. That 4.8 is a trip

[@richardholdener1727]

Gale and I don't agree on the boost gauge-my point was that the pistons and rods don't know what the boost is, only the cylinder pressure. The Boost gauge can be used with great success on relative changes, but I wish Gale all the best on selling the general public on his Fancy mass/density/temperature measurement!

@@hendo337 I hear ya. I still love my blue ovals but Chevys definitely has some good stuff.

[@cardboardkiller6883]

@K____ R____ if you look at the cost, you can buy 3 LS motors for what 1 coyote 5.0 costs. If you look at Ford's history, they have always been competitive with Chevy & Dodge and have always done it with less displacement. It's pretty impressive when you think about how a 5.0L engine can rival Chevy's legendary 6.2L LS motor. Which is why Ford doesn't make a big block version. Stock Mustang GTs are pushing nearly 500hp off the showroom floor. That and fleet displacement regulations along with emissions standards...

See if there is any power difference or if the curve falls off at earlier/later RPM with different amounts of preload.

[@calebnation7797]

Boost also depends on the intake manifold(s), what turbo(s) size, etc. if you have a better flowing intake system, you’ll make the same power on less boost than a system with the same FI but a restrictive intake system. Example: I’m a miata guy. A popular setup is a GT2554R turbo @ 16psi. That’ll do about 225whp with 3” intake piping and 2.75 or 3” exhaust. The other popular system is a GT2560, which is a little bigger turbo, @ 13psi. With the same 3” intake/exhaust and the same size intercooler, the 2560 does 250whp@13psi.

I think you should do test again but at this point with everything we know that works well. Large ring gaps , e85 or m1 , Bosch 210s or bigger , 5 bar map and giant turbos 88s or so. Only thing to find out out than is when rods decide to say peek a boo. No limits on boost or fuel.

[@thatturbotruck]

The real killer is ignition timing and people trying to push 91 pump gas to that level. I know because I've pushed them on 91 until they broke. Now I use water methanol and I'm thinking of moving to e85 and meth injection on the next setup. I would definitely like to see a fuel vs ignition timing curve for a boosted 4.8/5.3 in a dyno video.
