- STOCK TRUCK vs FAST 102-WHICH TB IS BETTER FOR BOOST? WHAT THROTTLE BODY SHOULD YOU RUN WHEN YOU ADD A LOW-BUCK, EBAY 4.4L STS CADILLAC BLOWER TO YOUR LS. USING ADAPTERS FROM MACKDADDYPARTS (314) 435-2222, WE INSTALLED THE INTERCOOLED SUPERCHARGER ASSEMBLY ON OUR CAMMED 4.8L LS. WE STARTED WITH THE STOCK 78MM TRUCK THROTTLE BODY, THEN ADDED THE LARGER 102-MM FAST. WE TESTED THESE DIFFERENT THROTTLE BODIES AT TWO POWER LEVELS. WHAT WERE THE GAINS?

Ha you did this test, i went to ebay and saw a brand new one for $419. While I was trying to find macdaddy it sold. Two days later see the same one different seller same exact pictures $1158 bucks.
A video by Richard adds 700 bucks.
LOL, saw the same thing. Richard just destroyed the market by putting up this series of videos! They are no longer budget. I think the adapters are up there in price anyway.
Holdner tax. The new sloppy tax.
That's the problem it seems if it's attached to an LS price magically skyrockets.
@@thegrimstreaker4669 no, the price skyrocketed due to the advertisement of this video. They were attached to a LS before the video was posted.... lol
@@larrytaylor1964 YUP, now its again cheaper to go with an LSA which will support more power
As a positive displacement blower fanatic, these videos are awesome!
Howeverrrrr. Pulleys! Let's go! It would be a crying shame to do such a comprehensive test on the cadillac M122 bolted to a lowly 4.8 without doing a pulley swap!
A lot of people run the gt500 M122 with a 7.8" lower and a 2.5" blower pulley and make pretty impressive power for such a small blower, however they do have the advantage of DOHC efficiency and the motors love to rev into the 7000+rpm range.
Ain’t no low buck no more that guy raised the price from $800 to $1200 from yesterday to today
and the blowers are now over $1,000
Didn’t he already install that 102 in oart2
I'm a Simple Man, I see a Low Buck LS video from Richard Holdener, I click
plus dance music
So essentially, this video just increased the prices 500% most likely.
The true test we need.
Sure would like to see a 6.0
A 364 is just a 325 bored...
He did put this Set up on on a 6.0 it didn't Work a said he was gonna make another video and fix it but I've never seeing thou come
God I love that I found your channel
me too
Cool results! I have a gt500 m122 (same rotors as the n* I believe) with a 90mm TB on a LQ4 and it makes driveline wrecking torque/power, but never been on a dyno. Good to see I'm likely above 600.
That sounds like an awesome combination! Is there some place I can see this? Are you on the "eaton superchargers" group on facebook?
Venturi effect/bernoulli principle, as air passes through a example 2" inch tube that tapers to a 5/8", air pressure decreases and air velocity increases.
Great video Richard !!!! You are right on track. That 4.8 is a real powerhouse!!!!! Great job and thanks for sharing!!!!
Hey I’m so glad part 3 was a go after watching 1&2 ..cool
Richard your the best brother, like its baffling to me on how your able to learn all this valuable info and keep it all crammed in that brain 🧠of your🤯
Would love to see some 1 & 3/4" long tube (24") intake individual runners made on the cadillac adapters manifold configuration going up to a 90 mm turbo manifold cap. Long tubes would make up some loss for the turbo's lag coming in at 2800 to 4000. By that time the boost should be rising beyond engine need. For drivability, you know.
I did this test five or 6 years ago on a 3L 6cylinder with a 1.6L positive displacement super charger: removed 2.6inch TB from the 2.6inch mounting point to the twinscrew and fitted a 3.5inch TB to the 2.6inch opening.
I initially lost 15whp as the AFR was effected, got the AFR back to where it was and got back my 15whp plus an extra 17.6whp with no timing change but a slight boost increase of about 0.5psi... just to prove a point that the TB was too small for the application even with the 2.6inch restriction.
I now run a 4inch TB on the same engine with a 2.3L Whipple but modified to 4inch all the way to the twinscrew.
What would you have done,if you were using a Whipple, which has a 112mm/4.49” inlet ?
Four inch Throttle Body = 102mm
@@kyleallen3857 depends on the size of the Whipple, engine, mods and boost.
LS2 with cams and free flowing exhaust system on 2.9whipple around 15psi - gains would be seen upto and over the 150mm TB = 5.906 inches.
@@CosmosMBTS I’m curious, how you make the calculation that, “gains would be seen up to 150mm...”
@@kyleallen3857 It is all dyno proven found on the internet.
@@CosmosMBTS Well.....the only 150mm TB tests I have seen are for the Ford 150mm which is Oval, not Round.
The largest Round TB I have seen is 112mm
Please reply with a link to the 150mm results you are referencing g
190hp gain from a few bolt on parts is impressive. Port the blower and let’s see how much you can get . That’s what I would do if I had that on my car or truck!
Great video Rich! I’d be curious to see IAT logs with that thing tho
112 DEGREES
Would love to see how an ls7/ls9 cam would fair with the 4.8 supercharged. Also whether there is any belt slippage at higher rpms.
Yes!
Richard, can you recommend a machine shop to rebuild my engine in the Los Angeles/OC area?
we use L&R or Dougans
We need a police swab test immediately update two years later
Great info!!!!!
Slap this setup on one of the 5.3 based 383 stroker motors and see if it builds power.
Thanks, now I am even poorer, figuring out what I actually want to do to my ls trans am
Whaaa, wa, waaaa! I’m doing Richie’s special effects lol!
yes
Id have a 102 flange adapter at the SC and 102 intake tube for the tb to mount to
Awesomeness, Richard turn up the heat and add some timing with the e85.. let it eat an let's see numbers before spark knock/detination at 100% duty cycle..
He says he knows what he is doing with E85, even if he isn't doing what all of us are out here running E85 for over a decade. He likes to run it like its pump gas, which is his prerogative. It will run like that no problem, he is just leaving power untapped is all.
@@SweatyFatGuy I know i wanna see him turn them 7200 . Great videos for cam gains
Building a 6.0 would like to see an old school BDS run
Great testing once again
Another video with great content . I'm not sure how I feel about this particular blower though ......
...because almost 600 hp & ft lbs isn't enough from a 4.8, or because a tvs series would cost 4x as much and must be 4x as rad, or what?
I wished you would have done that with a 5.3 . I'm installing a all aluminum 5.3 In my 88 K5 blazer. My buddy that works at the caddy shack had the same blower he is trying to sell me.
it works on a 5.3l or a 6.0l too
Those supercharger have gone from $400 to almost $1200 now. So no longer a budget or cost effective build
Best ls content
I really liked this video series of the cheap supercharger but it kind of got ruined by the price almost tripling. :(
Right on
love these videos! keep up the good work!
I think you should do a northstar motor big bang I have always heard they are very weak motor but I don't think they are as weak as people say they are
Old video I know but has anybody talk to them at Mack daddy parts lately? Haven't answered any emails and looks like everything is out of stock
Need to Velocity stacks added to those throttle bodies. Hint Hint.
Should slap a turbo on there too. See if u can demonstrate boost response comparison? Like time graph showing boost vs throttle percentage w.o using the brake. If the engine dyno can do that
THROTTLE % IS 100 ON THE ENGINE DYNO
@@richardholdener1727 i was thinking run it up to whatever rpm u want to start at. Simulate a roll-start w.o using the brake to build boost. Start the graph and slap the throttle wfo. Cause then the time would show how quickly it builds boost and accelerates thru the rpm range. Just an idea. Works well on chassis dyno idk bout engine dyno
In part 2 he talked about a 6.0 and other things, not wasting 30mins talk8 g about a TB..this video could of been finished in under a min..
Three really big!
How about caddy blower on L99 4.3 v8? .....Could be interesting
Ouuu I’m so happy found the blower for 500 and some adopters for 300 6.2 here I come
Adapters for $300 - where?!
well now there are more options to boos an ls wonder what 6.0 put up with this setup
That dyno cell must be so loud with open exhaust. These blowers whine more then my ex and your can't even hear it.
Unless you REALLY want to be boosted I feel like this supercharger is just not enough for LS
Plus sadly by the time you adapted to it you have more in it than you would in a low Buck turbo setup for 1,500 to 3 Grand you can turbo most LS setups and make more power without all the heat
Any boost is better than no boost
It added 50% more power with gobs of torque everywhere on an engine that already had a mild cam, higher compression pistons and a tune..pretty damn good really, especially since they haven't even changed pulleys yet.
But sure if your goals are to make over 650hp this probably isn't the right blower.
Keep in mind, a blown 600hp engine will have a crapload more torque than any NA 650hp engine everywhere in the rev range except for the last 500rpm..
I've watch the 2 vids before this and I'm just seeing the intake is in the rear 🤦🏾♂️
Were you surprised that the shape of the curve changed when you went from naturally aspirated to boost? On the naturally aspirated curve, you have more horsepower than torque, but the boosted curve has more torque than horsepower. Typically, on your other tests, when you add boost to a given combination, the shape of the curves don’t change… Correct? Does that have something to do with the fact that you backed off the timing when you added boost?
WE CHANGED THE INTAKE MANIFOLD DESIGN WHEN WE CHANGED TO THE BLOWER
And softened the ignition timing under 4500rpm?
Undersized/undersped/restricted inlet blower will do that.
I wanna see u add turbos to the supercharger that is what am trying to build
WATCH THE COMPOUND BOOST 3800 VIDEO
nice !!
Are going to put ported or aftermarket heads on this or a 5.3 version with this unit?
How about a smaller pulley
Is the 3.5” pipe really such an issue since throttle bodies aren’t 100% efficient due to the blade? I heard they’re around 80% efficient. Thoughts?
the 102mm throttle body flows more than the 3.5-inch tubing
How come every time you talk changes in timing, you tossup a picture of a fuel map? I want to see those dangerous curves of a timing table! 8:54
I tell you what the timing is
@@richardholdener1727 yep you did
Port the blower opening
Have done any rests on propane fuel?
no sir
Four inches!!!
How much of the increase was attributed to removing the mufflers
none-the supercharged motor never had mufflers-the na motor lost zero power from mufflers
Why are you going over stuff covered in oart2 already come on bro ...you already did this in part two...
Ls3 90mm 4 bolt will work with that blower.
THAT IS DBW
How about 2" headers on this blower motor?
DON'T THINK THIS POWER LEVEL NEEDS A 2 INCH
Where the nick Williams at
Have you tested the old vs the newer. Tbss/nbss intakes? On a stock engine?
Yes, he has a video titled "biggest LS intake test" if I recall correctly. But he has quite a few LS intake videos, might have to watch a few of them.
I have a video up with ALL the ls intakes
Is the bov necessary? I dont think the guys from mack daddy parts are running one on their setup.
Only if you want decent fuel economy when not running under boost. It makes no sense to be running with the supercharger boosting under throttled conditions.
@@andyharman3022 I'm sorry, I dont understand your response.
@@claytonhaske If they blower does not bypass the air it moves at say idle, part throttle, or deceleration. It would be boosting against a closed, or mostly closed throttle body. This is extra heat, parasitic loss, and wear.
it was just a piece of tubing I had-the valve isn't hooked up
this had an internal bypass valve-which we used
Did I miss it? How much boost is it making
11 ISH PSI
I'd appreciate seeing some different pulley sizes, even some lower boost settings.
@@richardholdener1727I'm running something similar. A gt500 122 on a 6.0. dem on facebook makes an intercooled adapter that lines it up. With stock balancer an gt500 pulley it makes about 15lbs
Personally I blame squirrels
So why did you stop at 650 pounds of torque do another 5.0 and split the thing in half show us what they will really take come on now. So upsetting when you say the your here to stop all the myths??? then you don't split one-half and show us what it takes!!! b-real take a stock 88 5.0 short block. No aftermarket Pistons none of that put ring Gap in it and boost it till it goes boom!!! Come on now. Please
And yes I know this has nothing to do with the current video so don't point it out idiots
Not just they block at that power level is ready to go they will bend rods at that power level which will take out the block as well I personally haven't seen very many stock block 5.0s that have made more than 650 ft pounds of torque the ones that do make it much higher than peak torque so it's not as bad on it but the whole motor is a crap shoot at that power level
I have an 88 5.0 (with ring gap) in my 68 cougar getting ready to get it back on the road with a gt45 and I'm going to put all the boost!!! and then nitrous till I break it so I'll tell you what it takes. Mph& et 1/8 m. 2900lb. At Barona Drag Strip. PS. I know what im doing.....than 5.3 gen4 and another gt 45🙉🇺🇸
this is an LS-we've run stock blocks to 1300+ lb-ft ft!
Fords dail at 650 -700 fb
Gm s routinely make it to 1300
Hmmmm which to choose?
@@safetyfirstintexas yes I know that and I'm going to put in a 5-3 but the car already has a good running 5.0 in it so why not blow that up first?
