Great concept, could get this engine in the Golf Gt and the Polo GTI, Unfortunately its one of the worst TSI engines ever produced and didnt last long at all, too much costcutting and downsizing...

[@surf4luke]

We run aircraft engines lean all the time, its called Lean of Peak (LOP). It's the most efficient operating point, but you have to transition from rich (continue to lean) through peak EGT which has to be done carefully (quickly) else you can damage the engine. EGTs and CHTs both fall off in that realm. We don't do it for high power settings though, that's always full rich for detonation avoidance. The take away is a truly lean setting is actually cooler and more efficient, that's why that excess boost brings down Temps in diesel, your staying in the lean of Peak realm. Diesel thermodynamics aren't so far off from Gasoline as folks think, boils down to mixtures mostly

[@hendo337]

Diesel isn't like gasoline, the EGTs get high from rich running not lean.

[@ekner]

@@hendo337 You're proving the point of surf4lukes last line nicely.

[@johnhonda93]

​@@hendo337 the difference is diesels are always running lean. If you're running rich in a diesel you're just gonna get a bunch of black smoke. And if you go far enough the egts will start to go down again instead of going up. It just takes a ton of extra fuel that you're wasting.

​@@hendo337 If you actually understood what the OP said, you would realize you are saying the same thing though the OP is much smarter.

[@iainball2023]

​​​@@hendo337 not quite true, its not "rich" yet. Diesel egt does the same as petrol. You just start in very diffrent places. A petrol engine won't run at anything leaner than 18 to 1. It's chemically correct at 14.7 to 1 Peak egt is around 14.2 to 1. It makes the most power at 13 to 1. It blows black smoke past 10 to 1 A diesel will run at 30 + to 1. It will run efficiently around 28 - 25 to 1. It will run hard 25 - 20 to 1. Getting a bit smokey. It will run harder at 18 to 1. Lower quality engines will start to shed parts. Starting to roll coal. 15 to 1. Runs so hard you will have to have a beefy engine to handle the forces. Also a gas mask, and a way to see through thick black soot. 14 to 1. Peak egt. Everything past the exhaust manifold melted two steps ago anyway. But it still isn't quite chemically "rich". Diesels use turbos in an effort to burn the required amount of fuel at the highest avaliable Air fuel ratio, to lower soot. Its essentially soot burning in the exhaust gasses that cause the egts to get to critical levels before you get to the fuels chemically correct, or full power air fuel ratios.

[@jasongaunt]

Jimbo! 2 things buddy: a). That boost hose is nice and cheap but any amount of heat will cause it to deform, twist and eventually stop allowing airflow (has happened to me) b). A restrictor pill inline on that hose will dampen the needle on that gauge and smooth out the reading :)

Looks like regular reinforced silicone hose, if so it;s very temperature resistant. If it was deforming in your install then either you had it installed with a twist/excessive bend or it was somehow exposed to manifold vacuum (they collapse under vacuum very easily).

I think it would be interesting and probably work quite well if you kept this modest supercharger boost than added the turbo system so you won't have the lag, depending how well it works and how well you can deal with the wastegate, it might be best to get an electronic wastegate system so you will have total control of your boost, that way youncan tune it to come on strong down low, then baby soft it through the TQ spike to protect the engine then feed in the power upstairs a little more to make it perky while still safe.

If the intake valves float due to boost they are just improving the cam timing. Poppet valves are check valves, so they will close themselves when cylinder pressure exceeds intake pressure, unless held open by the spring or cam. valve float due to high revs is a different story

I woulda started the acceleration run in 2nd gear at full boost. It seems like a waste of time to rev up 1st gear and then shift to second. In past videos, you'd usually start in 2nd or even 3rd in some cases and let the CVT do most of the work. I think that's the way to go. That first gear test was a bit of a let down considering how much more boost was added.

An electric PTO clutch from a lawnmower ought to work nicely for a small supercharger like that.

[@1NIGHTMAREGAMER]

id recommend not venting all the pressure all at once by putting some resistance on the output of pressure release since most blow off valves go pshhhhhhh not psh since i think might be issue with all boost disappearing all at once its best to do some research to verify what i said i just have slight concern thats all

[@Turbochargedtwelve]

Just a heads up, pumps in general draw MORE power when they aren’t restricted because that means their mass flow rate goes up and the do more work. That is to say bypassing air in your diesel has a strong chance of making your fuel economy worse. Additionally you say adding air to a diesel without adding fuel doesn’t add power and that is not strictly true. Adding air increases the effective compression ratio of the engine. Higher compression means higher efficiency, means more power from the same fuel. Of course with your governor it may likely just defuel to maintain the same power.

[@JCGver]

This is a fixed displacement pump (roots style), so it in theory will always flow the same volumet of air for a given RPM, the amount of work it cost to move that set volume is pretty much directly connected to the pressure differential from inlet to outlet.

[@erik_dk842]

@@JCGver Maybe if he bleeds the excess pressure back to the intake of the blower?

[@michaelblacktree]

Sounds like the intake temps are getting a little toasty with the increased boost. Maybe time to revisit the intercooler?

[@woopimagpie]

That was quite a lot of effort for not a huge gain, but it's still progress. And yes, I realise this is just a stepping stone to the next modification. Like everything, engine modification for a specific goal (economy, performance, outright power, whatever that goal may be) like everything has a law of diminishing return. I'm reminded of the old motorsport adage "speed costs money, how fast do you want to go?" The trick I guess is find the sweet spot where both the goal and the cost objectives are both realised, within the bounds of sense. This marvellous little project hasn't begun costing silly amounts, and I suspect it never will, because the priority is to do it as cheaply as possible. As many have already stated, this series of videos is more interesting that most of the big budget builds. I'm fascinated to see what Jim is going to do next. It's bloody brilliant.

[@enwri]

Ever tried injecting propane into the intake air at the same time your boost valve closes?

[@REVIEW_JUJUR]

*If u want Power Increase by adding more fuel, u can just simply spray LPG/Propane to the intake with a solenoid and a button (kickdown)… Diesel loves Propane. FYi i modded all of my cars to run on Propane/LpG, it has higher octane rating of 100 and much cheaper than gasoline (LPG just cost $1 for 5liters gasoline equivalent). My cars also has switch to use gasoline or Propane, but 99,5% of the time i always use Propane.*

[@ChiEKKUsama]

When you're done with this project, please please please do a massive overdrive to see the absolute max possible boost. I know it means increasing fuel use, but it would still be cool to see.

[@hendo337]

Put one on a small displacement motorcycle. I have had some daydreams about trying an AMR500 on something like a KTM Duke 390 or Husqvarna Svartpillen 401 accept instead of driving the blower with the engine, my idea was to have it driven by the front wheel mounted on the front forks, then passed through a flexible pipe to the engine, at lower speeds in lower gears those bikes pull quite well, they show their lack of power once the speeds increase, the idea was to gear them up with a different front sprocket that raises the speed at redline in the higher gears and once the bike is moving that fast the front wheel is spinning the blower pushing in boost to increase the top end speed and power of the bike.

[@truthboomertruthbomber5125]

@7eis - I’ve been thinking along those lines. I’ve got a 74 Beetle project that’s stalled out at the moment. The Predator V twin and this Kubota are more interesting. A 50s or 60s Fiat 500 or 600 would be a fun car to do engine swaps. Lighter and possibly better aero than the Renault 10.

If you relief the compressed air out from boost pipe, then the needed power to run the compressor goes up. Cause for this is the liters of air (or cfm) the compressor moves. Less resistance -> more cfm -> needs more power. Thats why normally mechanical compressors never use this style of boost control.
