Thats actually torque too.

Technically yes but at that rpm the poor gsxr isn't making much at all ... haha not that it ever did Tongue

(12-07-2010, 10:24 AM)ForcedInduction Horsepower is nothing more than math for torque over time.
The GSXR is faster on the high end because it makes its power in the 11krpm range while the Buell is mid-9krpm peak power. Its the same way a 3.0L car engine makes only (for example) 200hp yet a 3.0L F1 makes over 900hp and a 1.3L Geo makes 80hp while a 1.3L RX-7 makes 145hp. RPM. Ditto with many Finns revving their engines over 6000rpm to make inflated power numbers.

Yeah GSXRs only make power over 10k, under that they are useless. The Buell is just a torque monster with a flat line of beauty
   

If I could revv my Buell to 18k i'd make all kinds of ponies!

Yep, pull the governor off and you get instant "free" HP, but it kills the engine quicker.

It's also why we need a transmission, to bring the RPM back down to where there's enough torque to turn the wheels.

Now here's another opinion, which is as over-exaggerated as the others.

Okay, so you guys first want infinite tq at almost no revs at all, thus making practically no horsepower (but it doesn't matter, a bus engine sure is faster than F1 engine on same chassis). Then you complain that a merc bottom end won't hold up that tq..

(12-06-2010, 06:54 PM)ForcedInduction Thats been the case for a long time, but most Finns don't pick up on it. Watch a bunch of their drag race videos; You'll notice the 400hp engines are usually faster than the 500hp ones. Why? The 400hp cars get "on power" quicker because they have more torque low in the RPM range and their turbo spools up quicker.
Seriously, you watched a video and that's all the truth? How do you know how much power those cars had? In real life the 500hp cars are faster. Come and see. Doesn't matter if there's not infinite tq low down. Use gears, that's what they are for.

Why did MB make N/A 250d and 300d? They don't have any tq at all, not low down nor in the upper revs.

Some want a car that is like a N/A 300d as daily driver, but when on revs, makes 500hp if needed. The N/A has enough tq to move a passenger car nicely. I wouldn't put that to a bus, nor a bus engine to my car.

No, we want an engine where the torque curve is shifted lower down in the RPM range, so it comes on quicker. Not necessarily one with more torque, just one with a better spread of the existing torque.

The fact is, unless you're racing at 5Krpm, there's no NEED for the torque to be up there. It's nice, it's fun, but I'd rather have it at the low-end so I can floor it at 2K and be putting enough power to the ground to pass that rice-rocket that's doing 30 with the subwoofers rattling the windows, instead of having 500HP way up at 5K where i'll never see it anywheres but the dyno.

Why gasoline engines rev higher? Because they rev. So why not diesel? What is the broplem if diesel make power high rpm?
What is the problem our engines because they give maxs power at 6000rpm?

but they where trying to make a lot of power from 3k rpm up to 6k instad of peaking we want some power down low!

This would be our ideal power range!

A gasoline engine revs higher by design, because they have to offset the lower torque values that come from burning a less energy dense fuel.

There is no problem with a diesel running at a higher rpm, it's just that most non-benz diesels top out at ~ 2400ish. These things already rev more than fast enough to replace a gasoline engine of the same displacement.

I'm not saying it's not a nice thing to have high-end torque and hp, it's just that most people would like more torque on the low end to get up to speed quicker, in trade for less absolute maximum high-end Hp that they won't see in day to day use.

Unless the speed limits in Finland are ~ 300kph, or the car is taken to the track daily for speed trials/drag racing/drift competition, then it's just pissing money down the drain in an ever twirling spiral till the head studs break.

All I can say is that if you meet your power goals then you are successful. Everyone has different goals and it doesn't make it wrong to get a power curve that is higher than what YOU want.

As a collective we can take ALL of the information and use it to build a good reliable motor and the information gathered will help you make some good choices as to how you can achieve your desired goals.

I for one like to see our Finnish brothers push the envelope and see how much power they can make. If they could rev it to 8000 then good for them if they can figure out how to keep it together.

It is not about wasting money, for me it is to see if I can do it. I probably have spent more money on fittings than some have spent on their entire projects. I do it fo myself and don't really care what anyone thinks...if I did I wouldn't post pics of what I have done for fear I might not like what I hear.

It's all about finding a balance. Do you want to pull stumps(or get on power out of turns without down shifting), or have a 1000 rpm powerband at the top of the rev range.
For everyone that's a different answer. For me I own a sport bike with a 14k rpm redline and I want a diesel car that pulls like a train from 2k-5100(what I understand to be the theoretical max rpm based on diesels slower flame front).
Also Audi doesn't rev the R10 past 5k and I figure those guys know what they are doing.

Quote curtesy of http://www.mulsannescorner.com/juhaAudiR10.html
Quote:Now, there isn't really anything radical in the Audi R10-engine, but it is done with the most modern existing diesel-technology. It utilizes the third generation Bosch piezo-actuated injectors capable of handling 2000 bar injection pressure, an aluminum crank case (MB has an aluminum diesel in production), catalytic soot filters, and variable-geometry turbine vanes. It utilizes partly synthetic GTL-diesel fuel (Gas-To-Liquids) with setane number close to 70. This means a short ignition lag, which in turn means fast burning and the possibility to control maximum cylinder pressure with a clever injection. Traditionally the Achilles heel of the tuned turbo diesels has been the head bolts which have yielded under the maximum cylinder pressures. With a high setane number one can make the maximum cylinder pressure peak wider and lower.

The operational rev band of the R10 is an impressive 3000–5000 rpm. Tom Kristensen, "The best band is 3000–5000 and you can go even a bit over." Tom continued to say that the band is quite narrow, but if you think about it, it is actually 40 % of the total band, which is much, much more than in many race engines. He is probably used to the very driveable FSI-engine. The race tuned turbo diesels usually have a relatively low compression ratio and a high boost. This easily produces an engine which is not as driveable at part load. Tom may have noticed this and interprets it as a narrow band. It may be a tricky band but not a narrow one.

It appears that the restrictor does not limit the engine power. With a stochiometric ratio the engine could produce about 800 ps. Yes, of course, diesels require air excess. However, the maximum allowed boost seems to be the real limiter. Audi tells that the top power of the R10 is about 650 hp. To get this power at about 5000 rpm and 2940 mbars requires a very high volumetric ratio i.e. excellent cylinder fill. In practice, the R10 must have a very efficient intercooling system to get the required air mass into the cylinder.

The maximum torque is above 1100 Nm (810 lb-ft). The R8 generated about 700 Nm (520 lb-ft). If the R10 works as turbo-diesels tend to, the maximum torque is constant 3000–4000 rpm, above which there is almost a constant power band (diminishing torque). The Audi engineers have calculated that the R10 could do one ore lap with a tank full at the Le Mans Sarthe track. This would mean that the R10 is about 5 % more efficient fuel burner than the R8 FSI over the track. The Sarthe is about 80 % WOT (Wide Open Throttle) so the difference is not that enormous. At tracks with a higher part load percentage (Sebring, Road Atlanta) the difference is going to be bigger.

It's all about finding a balance. Do you want to pull stumps(or get on power out of turns without down shifting), or have a 1000 rpm powerband at the top of the rev range.
For everyone that's a different answer. For me I own a sport bike with a 14k rpm redline and I want a diesel car that pulls like a train from 2k-5100(what I understand to be the theoretical max rpm based on diesels slower flame front).
Also Audi doesn't rev the R10 past 5k and I figure those guys know what they are doing.

Quote curtesy of http://www.mulsannescorner.com/juhaAudiR10.html

Quote:Now, there isn't really anything radical in the Audi R10-engine, but it is done with the most modern existing diesel-technology. It utilizes the third generation Bosch piezo-actuated injectors capable of handling 2000 bar injection pressure, an aluminum crank case (MB has an aluminum diesel in production), catalytic soot filters, and variable-geometry turbine vanes. It utilizes partly synthetic GTL-diesel fuel (Gas-To-Liquids) with setane number close to 70. This means a short ignition lag, which in turn means fast burning and the possibility to control maximum cylinder pressure with a clever injection. Traditionally the Achilles heel of the tuned turbo diesels has been the head bolts which have yielded under the maximum cylinder pressures. With a high setane number one can make the maximum cylinder pressure peak wider and lower.

I'm not trying to piss in anyone's dew, just going back and forth in what I think is a good discussion. I know everyone has their own viewpoint, but it's fun to toot your own horn every once in a while. Big Grin

I'm one to dig for reasons behind, and give my own reasons, so it can sometimes come across harsh. Add a slight language/customs barrier, and it gets even more muddled up.

Looking back, the "pissing down the drain" comment wasn't the best way to describe my thoughts on the matter, I was trying to state that for most of us, trying to get an insane amount of HP and high revs would be a futile waste for what we expect from our cars. It'd be like having a solid gold toilet, or a ruby studded feather duster.

That being said, I've dropped well over 4 grand into my swap over the past 3 years, and it's never seen pavement, so I'm not one to talk about pissing money away...

Those R10 guys don't have prechambers. It makes a difference. Jeemu has proven you can get max power to 6000rpms on OM60x.

(12-07-2010, 04:50 PM)300D50 Unless the speed limits in Finland are ~ 300kph, or the car is taken to the track daily for speed trials/drag racing/drift competition, then it's just pissing money down the drain in an ever twirling spiral till the head studs break.
Yeah. Then it is a total waste of money doing anything other than oil change to OM615-617 engines, why not just buy a new 2-litre VW diesel which has a lot nicer tq curve and consumes way less.

But seriously, Rudolf said it. It's to see if one can do it. Also, hobbies aren't to be rationalized.

It's normal to rev the engine past 3000rpm in daily drive. I've had N/A W123, it needed to be revved in order to just keep up with traffic. Successful overtaking was more due to surprise than torque Big Grin

And to you guys who are so obsessed with low end torque, why don't you put on a supercharger and gear it up until you push the crank out of your car. Than we can learn something from your low end torque testing instead of listening to your constant complaining about the high end testing that Jeemu and Muuris does.

Is that any different than pushing it out at 6K rpm?Dodgy

The idea isn't to make 10billion N-m of torque at stall, but to add some pep where it counts for our applications. I'm after low-end torque because my engine's going in a compact truck, where top speed isn't the goal, and being able to haul around a full beds worth of crap at 55 without winding the engine up is.

VGT are better for low end torque and Holsets are better for top end power

Geezer got it correct; Flame front velocity, g@soline burns much faster.

At 6000rpm your piston velocity is only 16.8Meters/second, yet a stock small block Chevy has 17.7MPS@6000rpm (and goes to 23.6MPS in modified 8000rpm SBC engines).
So Jemmu, why cant your superturbo's pistons move as fast as a stock 'merican pushrod all-iron antique?

Won't matter, its not mass thats the problem. Spinning the engine faster only means the flame front can't keep up and no more power is made, possibly even less.

Well theoretically, if these motors run forever (for quite some time). Why not run them up high for the time being you will own the motor. Most definitely the motor will survive what you do to it for the amount of time you will play around with it. Sooner or later the motor will be tossed aside better bigger better projects will arise, or it will be time for a more drastic measure possibly better rebuild not sure.

To me it's rather personal preference, and if the way you run your motor will work with your application.

So be it, leave the ones that beat the piss out of there motor to make large numbers up high in the rev range. Because I will be one of those guys. Who wouldn't want to take a om motor to 6k regularly?

And to those, who are not fond of this practice on these motor's, start your own thread's some do already, and start making some progress of down low TQ, and your motors built specifically for your applications.

And leave these guys from across the pond alone, if anything encouragement would be the best thing. Because I sure as hell want to heard updates from these guys on how these motor's survive.

I wonder that i can make 1.9 Bar Boost almost 30 PSI at 5000 RPM, at only 90,000 TURBO RPM, What is max RPM on this turbo. ?
If i rev the engine to 6000 RPM i need around 110,000 Rigth.

90k is the service limit, should be fine to 120k though.

Thanks OK it seams i am far from the limits on this Turbo. and dont even have a external wastegate.

Yep, even the larger 451 turbos are spun up to 100k rpm stock.

Here is a capture from a road test with one.
   

See even stock the turbo has a EMP:boost ratio better than 1:1! (21psi:29psi)

UPS maby there is a software issue it seams to max out on 90909 RPM every time.
I will try to find the Error, so maby it spins faster ?
Get back when i find out.

Im pretty interested in your RPM gauge. Are you using the stock HE351VE shaft speed sensor?

Yes it is the stock sensor, 2 wire the one wire to ground on the arduino board.
And the other wire directly to an digital pin.
And then counting emery time the pin go high
And it is working i have had it to 103,000 RPM now. motor at 5200 RPM Boost 1.9 Bar

I haven't worked with an arduino yet. Does the digital pin have an internal pullup or does it require one?

Do you know what kind of sensor it actually is?

Yes the arduino has internal pullup.
Iam pretty shure it is an inductive one, so only metal has to go by it. and the magnet is in the sensor. i actually just connected it and was quite chocked it worked :-)
You can see the code here.

Its just a hall effect sensor like used on the crankshaft pin. The turbo shaft has a flat on it which breaks the signal. Some turbos do the same except they use the compressor wheel's blades instead (My HE341Ve used this).

I just pulled the sensor out of my spare turbo and you can see the flat on the shaft through the hole.
Someone had told me there wasn't anything on the shaft. Rolleyes

Nope. It's a VR sensor, since it produces AC voltage.

Better be careful, at 100Krpm, you could be generating some pretty high voltage spikes from a VR sensor.
The clamping diodes in the AVR on the arduino board might handle it for a bit, but you really should look into a preconditioning circuit. I know the megasquirt guys use them for their vr sensor inputs, not much to them.

I was having issues with my vr signal doing that with megasquirt on my Volvo. It would do weird stuff around 9000rpm. I changed a few things in the conditioning circuit and it cleaned it up.

(01-13-2010, 05:05 PM)tomnik Hi,

ad 2) I can send you photos of a water/air IC (AMG off a 600 bi-turbo) I will use after long research for good quality and small dimensions.

ad 4) I welded an adapter plate directly to the turbo after cutting away the turbo's original flange

Tom (Germany)

Tomnik can you please provide a part numver for that intercooler if you read this? Thank you, Karl
