Have you figured anything new out with the caddy blower?? I have one that's ported with a 2.4 pulley sitting in my garage as a spare for my sts-v. Wondering if it's worth putting it on my e36 5.3 lh8 swap. It has a aftermarket lid on it as well. In the sts-v world it's called marks lid. The Lenova coils are crap from the factory and heat soak on the first pull. Marks lid has a huge bar and plate brick in it.
I watched a few of your videos on 6.0 Cadillac super charger engine, i was planning about the same combination. Did you get figure out why it wasn't making the power it should. Could it need a bigger throttle body? I would love to know the results. Thanks
I hope this is not too much ask! Im have a 370 ls built at the machine shop be built he ask the compression i want and i told about 9.5 ratio and the cam since i told him i was super chargering it. He want to go with a blower cam , i picked the comp cams 54-337-11 because I was going to buy the Cadillac blower later. How much hp power did the 6.0 with the Cadillac blower on your last test and what kind lifters did you use? And thank you for last response! Im just trying to find out if I'm making the right decision.
I still think it’s ignition related. Park the thing at 5,000 on the dyno and slowly roll into it. If you see it nose dive past a certain load you know it’s dumping spark. I’d think you’d see that on the wideband also.
I don't know if you'll see this or not, but could you do a video on the old Air cleaner lid flip? I know kids back in the day would flip the lid for the cool induction noises it made, but now it causes an argument these days about whether it actually kills horsepower. Anyone who knows anything about engines knows air cleaners are restrictive and actually perform better when removed but I think it'd be a cool side test to do when you do another carbureted engine.
I have changed my mind from a collapsed lifter to a supercharger issue. I rewatched the dyno video and I don't like what the tensioner is doing. I watched a couple other guys with videos of m122 blowers and the tensioner doesn't rattle around nearly as bad. It moves almost linearly with expected load and like 1/2 as far. It's not spark, fuel, boost. It's a chopped valve or a severe drag on the crank and guessing by the power curve, the blower gets up to a speed and starts to eat. I have had this with a waterpump, believe it or not. Would spin by hand like nothing was wrong but once it got up to speed it would start slowing down and lock. It wasn't small either, it had an 85hp Deere engine pushing it. Edit. I just watched the 4.8l m122 stsV test video. You can see the tensioner in the dyno video as well, it is definitely not flapping like a penguin within bad breath range of a seal. Something has changed.
That looks similar to something I have encountered on older watercooled VW motors when the crankshaft key way would shear and the cam timing would advance a bunch and power would fall of a cliff after 4000 rpm
These blowers have a spring loaded coupler inside the blower like the LSA supercharger, could be the coupler is bad and maybe at higher RPM/Load it’s not spinning the blower anymore. They sell a solid isolator for them, I bought two for the 2 blowers I bought last year.
Check timing with a strobe. Use an oscilloscope to confirm spark dwell and injector pulsewidth. A quick test to confirm that that side of things is correct.
The fact that the boost kept ramping up through the entire pull is what's really throwing me off. That rules out a blower issue or a bypass valve. He also said it's not going lean and there's no sparklies in the oil. I'm thinking it's maybe a wonky lifter, but more likely an ignition problem.
Seen this before in a race car that just would not make power past about 5k rpm and it was a hairline crack in the rocker - I kid you not - messing with the ECU via harmonics and interference with various sensors. The log was all over the place on some traces. Replace rocker arm: data normal and problem gone. Cost a looot of money to find that out. That was an Al rocker, though, so not sure that would exactly apply here, though I'll never be amazed about what weird stuff can mess with engine management and give you really weird symptoms.
how much impact can it have, when some of the fuel injectors on each side spray fuel directly onto the surface of the adapters, instead of into the intake duct against the valves. proposal is to set the fuel injectors similar to those on Edelbrock's dual trottlebody crossram intake. possibly they come into conflict with bypass casting and trooltlebody parties
My ag-cat i've lost the blower twice, usually you know it when i can't develop power over 30 inches of manifold pressure. i know 1340 pratts not a ls but still a pump.
Richard-Ditch that cam. It doesn't work with the blower on this motor. Go back to something like the sloppy S2 or even a stock LSA cam, and I bet the problem goes away. It's not the size of the cam, it's just that this particular config didn't play nice and trying almost *anything* else will fix it. I bet the S2 would still make the big noise.
Thanks to the folks who are scared to talk politics we will now be paying more for epa approved aftermarket parts with no offroad use options. The easiest way to stop bad laws are to stop the Nazi left from winning elections in the first place. I wonder if you will even still be able to get a tune or computer for a naturally aspirated engine that can deal with boost this time next year. The way the law is written anything that controlls air coming in or out of the engine including the tune will be a fine for the builder/seller. Im going to bet that computers will have to stay with their oem engine and only epa aproved tunes will be allowed. If you want boost you will have to run an engine that came boosted from the factory with its stock tune or an epa approved tune.
I think the blower lacks volume. It was designed for a much smaller engine. The best way to test my theory would be to put the blower on a 400 inch engine and see if the power drops at an even lower rpm
@@brianfrost303 the blower did well untill 4000 rpm. thats when it ran out of capcity. if richard puts the blower on a 408 i predict that the power will fall off at 3500 rpm.
@@falfighter so you're telling me that if i get a 600hp 4.8L supercharged engine... bore/stroke it to 6.0L, install higher flowing heads and a much bigger cam.. it should lose 40hp because the blower suddenly becomes too small to even make the power it did before on the smaller 4.8L engine? Seriously? If you're willing to bet i'll happily put down my life savings saying the blower size isn't the problem.
@@brianfrost303 it worked well until 4000 rpm. at that point it was no longer providing enough flow to feed the engine. remember it was built to supply an engine that was even smaller than the 4.8. i think that there is nothing wrong with the engine, dyno, or the blower. richard is troubleshooting a problem that dose not exist. it is a mismatched combination.
@@falfighter so the crank driven blower magically **flows less** and **makes LESS horsepower** when bolted to a 6.0 instead of a 4.8? Certainly an Interesting theory you got there.
Richard. Did you pull every valve doing off and make sure no inners were broken? My buddy just had a very similar issue. Low rpm fall on its face. The valve springs ended up being too lite on the seat because of the boost. Shimmed springs. Fixed issue.
do you possibly have a guide thats hanging valve open with added help of boost or possibly some galling caused by water in oil lifter hanging in bore. does it get worse as it heats up?
@@hendo337 the 4.8 made 591hp. The 6.0 made 540ish with better heads. if you had a blown 4.8 and you ported the heads, and bored/stroked it to 6.0 Would you expect it to lose power?
@@brianfrost303 ahhh NO! Lol Ritchard is going to find it. I keep coming up with overlap on the intake and cylinder pressure is fighting boost pressure and she’s falling on her face then? Is the boost continuing to rise and it’s still falling on its face or is the boost stopping even tho rpm is increasing?
I love this video by the way. I'm 25 mins in. You've got adequate boost. Adequate spark, adequate fuel. Adequate timing. Adequate valve spring. It's starting to sound a lot like a mechanical failure. :(
@@brianfrost303 One of odder lessons I have gotten in life is what strange reason something isn't working. I went to the local techical school for auto maintenance. Me and my partner were the first ones to have an automatic transmission ready to test. Put it on trans dyno and couldn't get the dyno to work. After a few tries I noticed there was a housing on main drive motor was moving. Looked underneath and we found a loose speed sensor tightened it down and the dyno worked. We got bonus points in that part of the class for fixing a transmission dyno.
351W , gt40 heads, mild cam, for torque, hyperuetenic pistons, can I run 5-8 psi boost on 91 or e85? Can I blow through an Edlebrock truck Avenger carb?
@@hondatech5000 you saw the boost curve though, right? It kept adding boost all the way to redline. With belt slip the boost would be going all over the place.

So what was the issue?
belt slip most likely
Put a kv tester on the secondary plug wires and see if the kv is dropping off at the point of power dropping off ?The Holley acting up?
Let’s finish the caddy blower test were all waiting………
Hey the Toyota I force 5.7l tundra 2010
When are you going to finish the Cadillac supercharger with the Mac daddy kit??? We are waiting!!!!
What was the final verdict, what caused the power drop??
I’m wondering this too.

Any chance of drive slipping on the blower
Are the lobes pinned ?
Lifter going away?
