- HOW MUCH HP WILL NITROUS, A BLOWER OR TURBOS ADD TO A SBC? CAN POWER ADDERS, LIKE NITROUS, A SUPERCHARGER OR TURBO(S) REALLY ADD SERIOUS POWER? CHECK OUT THIS VIDEO WHERE I RAN THREE DIFFERENT SMALL BLOCK CHEVYS (305, 350 AND 383) WITH A VARIETY OF DIFFERENT POWER ADDERS. THE POWER ADDERS TESTED INCLUDED A ZEX PERIMETER PLATE NITROUS SYSTEM, A WEIAND 6/71 ROOTS SUPERCHARGER, A PROCHARGER F1A-94 CENTRIFUGAL SUPERCHARGER AND A PAIR OF CHEAP, EBAY (CXRACING) TURBOS! LOOKING TO STEP UP YOUR GAME, NOTHING ADDS POWER LIKE A POWER ADDER!

Crazy how easy the power is with anything forced induction. I know everyone is sick to death of combos like turbo LS or turbo SBC, but it’s sooo easy it’s hard to say no to 🙌🏻
LS and SBC are great engines but I even went to the Ford Coyote just to not do yet another LS swap.
180 k Awesomeness ! Congratulations
Personally I blame squirrels
My wallet hates this video lol
Wondering why the 350 made lower numbers than I expected with that cam and heads combo. I’d have expected to see 430-435HP. Too much head and smaller valves might have helped, like 1.94 & 1.56 for better airspeed? Quench was (?), chamber size and SCR/SCR were (?)
Dry sump, 40 pound stoker crank, 6” rods, .060 over bore, proper pistons, worked high flow heads,nice cam, dual plane intake, holly carb, headers. You know average daily street engine 🤣 add boost for increased pants ruining fun
Have you found the 638 and 880 roller blocks to be reliable at .060 overbore at over 450/450 tq/hp?
That 305 really did like the spray. Like 125+ HP and almost 150 TQ off basically a “100 shot”. Not bad at all for a .046 jet.
Right on
Please do a video of the 307 ci Oldsmobile engine that came in my 1986 Buick Regal
The thumbnail confused me!
Who the heck is giving this guy thumbs down?
I am proud to say I'm currently building a vortec 350. AFR 190cc heads, flat top piston. Not sure what cam yet since it is going in a Z71. I want to keep the power curve below 6K rpm. I'm leaning toward a First TPI. Since I can tune the factory ecm, that what I'm running it with.
Why all this for a Z71? It's cause I'm stupid and can't grow up. 🙄
Consider the Comp Xtreme Energy 08-422-8 or one of their Xtreme 4x4 cams in the same duration range with similar or a tiny bit less lift. Your heads can handle more airflow than these small to mid sized cams but a 4x4 really benefits from huge low RPM torque. I’m running the 422 on my 2WD 92 C1500 with 1.6rr for .528/.535”
What about all of them.
Nitrous fogger to keep the 88 mm twin turbos spooled pushing thru a cold air intake into the root supper charger.
I was hoping he said we tested them all together
Twin procharger into a 2 into one intercooler out into the roots blower with a nos plate between them and direct injection with mechanical pump. While you are at it add camless valve train.
I'm building a blown 396/402 on my channel now that I'll run in this configuration for a couple months. Long enough to get dyno numbers. Then I have a pair of ebay gt45s that will be set up as you speak of without the nitrous.
@ Richard Holdener , curious for the typical 23° 350-383 with 10-10.5 to 1 compression what do you consider your "go to" camshaft? Notice an aweful lot of 276/280 ish @.006 hydraulic rollers in catalogs, usually 108-112 lsa with lift all over the place as well as Vizard, and Lingenfelter books repeatedly saying that's about the max for a true dual use street car with emphasis on performance. Even a lot of your vids you use the comp 274h, or xr282hr etc.
THE 350 AND 383 WOULD GET DIFFERENT CAMS-THE 268 IS POPULAR FOR A TYPICAL SUB 400-HP 350, THE 383 WILL ALLOW MORE CAM TIMING
Or do a video on the 318 small block Mopar from the late 80’s
How about blow thru carb turbo and nos?
I am liking the video picture thing "power adders for sbc" feed them 5.0 L fords lol
I’ve been looking for the old whipple supercharger that was designed for under the hood Chevys with the TBI . It would relocate the TBI to the rear and turn it sideways. Do you know anyone still playing with that stuff?
i remember those
Umm...the thumbnail says 5.0 Ford.
fixed it
Hey Richard just curious if you’ve ever built a 352 400 block with 327 crank or if you’d ever do a video on one. Thanks
westech has a 372 using a dart block-used it many times
I just built a SB400 with stock crank. Forged 5.7" rods and hypereutectic pistons. Aluminum heads with a calculated compression ratio of 10.5:1
I did not plan on doing a power adder but I now want one. I did gap the rings for boost just in case. On this set up would all recommend 250 nitrous or Turbo if so how much psi boost you think it can take.
No matter what your compression ratio is going to kill any good boost.. lower compression=higher boost.. my setup is 383, forged eagle stoker crank, forged eagle h-beam rods, SRP -16 dish pistons, 205cc heads, 9.5:1 compression, haven’t completed the intake and carb choice yet but plan to run 15-20psi with twins. I recommend to run low boost on your current setup or it will not stay together long.
I would start with a smaller shot but yes it will also take boost
@@richardholdener1727 100? 150 shot?
@@DavidNewkirk why not start with 50 and work your way up?
Hello Richard. Can you please do a video on the difference between the gold and silver throttle bodys on the ls 6.0 engines with the 3 bold and 4 bolt, 6 wire and 8 wire . Can't find any info but the gold and silver turn opposite of each other and 1 won't work on the other. It's what I can find and it just don't seem correct information ????? Confused.
I don't run factory ECUs-so on the throttle size would make a difference
The gold one is for LS3 PCM and the silver one is LS2 and is the one compatible with 411 PCM as the gold one is not!
👍💪
If you would have upgraded the valve springs on the 305 what would you have used?
WHATEVER FIT-WE DIDN'T MEASURE IT
I’m a disabled man and I would love to come and volunteer to Lear some of your skills.
Can you run nitro methanol? Without it blowing up?
Richard!!!!
A just nitrous video for the future bbc or sbc ? 200-500 shot range plenty of plates can do that including those zex one s
500-hp plates? we've run 300 hp plates
No live tonight?
Speaking of power adders I have 256k on my 5.3 what’s the chance it blows up if I start adding more power there’s no misfire from what I can tell and still runs well with plenty of power
if you drive it right, im pretty certain you can put a 100 shot on it MAX and drive it around for around 20k miles. at least with my experience with stock engines, they hold up pretty well assuming preventative maintenance took place
all of our Big Bang motors had 250K miles before boost
@@richardholdener1727 that’s freaking awesome good to hear thank you
@@myguysponge7325 remember, what he can get away with for 30 seconds at a time with very low coolant temps in a short Dyno run is not what you can get away with in a car with 200° coolant temp, also you'll usually have to run a little more fuel, less timing for that kind of wot power when you plan to run it wot for minutes/hours at a time. Just saying optimal tune in your car will lower power output compared to the results Richard gets.
@@b.c4066 thanks this is something I didn’t really think about
Chevy 305 = always almost there LOL
How reliable is that turbo on a stock 350 bottom end
VERY
Thank you! It's hard ash tryna find any info and everyone says LS swap but im tryna make some power out the same motor 😂
Where is the video for us Mopar fans.
Don't you think you kinda robbed the 305 of more power by not changing springs? It seems like that's something you guys do quite commonly. I realize it's not ideal but on the dyno changing springs isn't too too big of a deal.
we run what comes with the heads-but peak power would not have changed
Yep Billy the kid
From the title I was expecting to see each engine with all different 'power adders'
Why don't you yose factory specs? You've skued number
we test them on the dyno before and after mods (nothing is skewed)
So stock 350 except for it’s a carb l31 with a turbo up to 9 psi no ring gap added how bad of an idea is that??😂
I would love to hear Richard on your question also
I would always add gap-you will turbo the boost up if 9 psi works
more nerve
