Hey guys,
I'm new to FSAE but not to turbocharging. I have done some extensive searching on the cbr 600f4i topic though and have pretty much come up dry.
Alot of teams that run turbos seem to lower the CP quite a bit. It is obvious why you would do this but, my question is. Since we are limited to 600cc displacement. Lowering CP would in advertantly cause displacement to increase over 600ccs.

For people running turbos. What PSI maxes out the duty cycle of the stock injectors? And are you experiencing overheating problems with turbo overspool?

I Just need to get the ball rolling a preposal before anything can be done. Just searhing out my options any input would me much appreciated
thanks alot
Jason

Hello Jason,

I assume you mean CR (compression ratio) when you write CP.

Lowering the CR by either shimming the head with a thicker gasket or milling the piston domes does not change the displacement.

Displacement is defined as the swept volume of the piston and that will not change unless you alter the bore or stroke.

[Pete M]

What Dan said.

Also, any 600 cc bike injectors should work fine as they're all good for at least 100 hp, which is about the most you can make with the restrictor in place.

Not sure what you mean by "turbo overspool". If you overspeed a turbo, either you'll blow the engine up due to overboost, or the CHRA in the turbo will come apart from the forces involved. You may overheat due to the increase in average power you're making if you don't size your cooling system appropriately, but this isn't really related to overspeeding the turbo.

[Orion ZyGarian]

I'd think you'd have to be doing something serious or seriously stupid to overspeed a turbo nowadays...wastegates are your friend! Use them!

Besides, it would be hard to overspin a turbo with 600cc's of displacement I would think.

Regardless I too wonder what the most common way of lowering the CR has been for turbo users; has anyone gone so far as to have lower comp pistons in addition to the thicker headgasket?

[Drew Price]

Remember that using a thicker head gasket, or using shims will alter or possibly eliminate the effectiveness of the quench area of the combustion chambers (depending on engine used, head design, etc). That is without adding any material of course.

I would be wary of machining down stock piston crowns into dished pistons, especially on some of the 600cc pistons I have see out of engines, there does not seem to me very much extra material, and unless your tuner really knows what they are doing, you may be fairly likely do be able to destroy stock pistons pretty easily. There are probably dished pistons available, and 4 custom pistons usually don't run over ~$1000, right?

I have seen claims of charge pressures in the 12-15psi range, there are past threads for specific cars that go a little more in depth about individual setups.

You could find what power level you can support with the stock injectors by just finding out what their max rated flow is (at what fuel pressure), and whether or not they are capable of sustained flow (some aren't, and I don't know anything about the CBR engines).

Best,
Drew

Over spool meaning. The inducer size is larger then the restrictor plate. therefore the turbo will spin faster to move the same volumetric amount of gas. Lowering the compression ratio keeping everything else stock would cause displacement to rise. but if you decreased the CR to a ideal turbo range lets say 9.5-10 the head would have to be significantly shaved to keep the same displacement.

Once again when i say over spool i don't mean OVER boost. Since the Restrictor plate is smaller then the inducer and the compressor wheel it will cause the turbo to spin faster due to the vacume created between the turbo and the restrictor plate.
Thanks again guys
Jason

I have lowered CP with a thicker MLS Headgasket before. Does wonders but for Hi-psi. i would think twice, but my current project is going to be running 21psi on a MLS headgasket.

[Biggy72]

The displacement is only calculated on bore and stroke. It has nothing to do with the compression ratio, shape of the piston or anything else. So unless you bore an engine out, or put in a new stroked crank with shorter rods then the displacement will be the exact same.

[VFR750R]

XU, changing compression ratio does not change displacement. No change in head chamber, dish volume or head gasket thickness changes displacement. Displacement is defined by the stroke and bore only.

The restrictor will not force the turbo to speed up, nor will it have to to displace more volume of air, it will mearly displace the same volume of air at a lower pressure (same volume at the inducer, but lower MASS flow rate).

the turbo can overrev due to the restrictor, and that is a good reason to have a wastegate control that has more variables then just boost. This overspeed will increase the charge temperature as the Pressure ratio rises across the compressor, but it is only an issue after choke and does not directly cause engine overheating, but can cause damaging detonation. Simple alogrithims of wastegate position with RPM or reducing boost demand with RPM both do an adequete job although more advanced techniques can be more accurate and robust.

By far my favorite book...theres all sorts of excellent info that everyone can learn from heading into forced induction.

Having read that however, I'm ready to step up to something "bigger", with more specifics, theory, and math involved http://fsae.com/groupee_common/emoticons/icon_biggrin.gif Any suggestions?

By the way, in case anyone else here is wondering what GT3076R and GT3582R compressor maps look like when applied to the Toyota 7M, I mapped these years ago:

Actually it does. Keep in MIND your CH the compression height From the wrist pin to the top of the piston Occupies a volume. when that is shaved down displacement is increased. The total volume is increased.

Think about it. And stop being very stubborn about it. You have the same bore same Stroke same head and HG. But the top of the piston is missing a Huge piece. TOTAL Volume is Increased. The ratio of how much the piston Sweeps to the total Volume of the Cylinder is Changed. Lowering the COmpression ratio

Alright I took the time to draw a diagram for the mentals here that have trouble understanding what i am saying or fail to read the whole post before jumping the gun
http://i2.photobucket.com/albums/y22/XRT09/CRdiagram.jpg

With the example cylinder of
you get the CR with the Total volumentric displacement when the piston is at dead bottom compared to the volume in the cylinder when full compression sweep is done 86mm. You get the two.
As you can see shaving the pistons will effect displacement. and CR ratio. at the same time. The picture just has randomly made up numbers to illistrate a point. I dont know where you kids are geting your intel from. But Hate to breat it to you its innacurate.

[Pete M]

Dude, you have now had several experienced engine guys answer your question in exactly the same way, and you honestly think it is us that is confused? You are misunderstanding basic engine terminology.

Of course shaving pistons will increase the total volume of a cylinder. Everyone here already knows that. Displacement is defined as swept volume, not total volume. It is swept volume that is restricted to 610 cc, not the total volume of a cylinder. Pick up an engine textbook and look up the terms "swept volume", "clearance volume", "displacement" and "compression ratio".

As for overspeed, if you tell your wastegate controller to try to achieve 21 psi of boost at 10,000 rpm on a 600 cc engine, you *will* overspeed the turbo. Or at the very least you will wastefully spin it much faster than it needs to be. A wastegate controller with TP and RPM defining aim boost could be used to prevent overspeed. But there are other more advanced methods too.

[Dan G]

Wow. Your new definition of displacement makes much more sense than the one thats 100 years old. Thanks for enlightening us! You're a genius!

[Big Bird]

There is something quite hilarious about someone meekly signing on here as a "noob" - and then within one thread and 6 posts they are calling anyone who doesn't agree with them stubborn and ignorant mentals who can't read. Jason, I have to say I admire you for your chutzpah mate. It's a welcome change from the usual "where do I find the formula to design a chassis" questions.

Unfortunately, I have to join the growing legion of stubborn and ignorant mentals above - some of whom, I have to say, are the most respected & articulate stubborn and ignorant mentals I have ever had the pleasure of dealing with.

I think you are wrong with your idea of displacement. You are considering volume at BDC as your displacement, whereas the volume at BDC is actually your displacement PLUS your clearance volume. Displacement is the amount of working fluid DISPLACED in one cycle from BDC to TDC.

Using your example above, every time the crank moves from BDC to TDC the piston moves 86mm
up the bore. In your standard engine it is stopping 4mm short of the head. From your bore of 84mm, I calculated your piston area as 55.4176cm^2. Therefore, for your standard engine:
Your volume at TDC is 0.4 x 55.4176 = 22.167cc
Your volume at BDC is (8.6 + 0.4) x 55.4176 = 498.76cc.
These agree with your figures, and your compression ratios are correct.

Now, if you were to remove the spark plug and fill the cylinder at BDC with oil/paraffin/beer/whatever, it would take 498.76cc of fluid to fill it to the bottom of the plug hole. If we then rotated the crank 180 degrees, the piston crown would move 86mm up the bore, and we would be left with 22.167cc of fluid trapped in the chamber at TDC (the clearance volume). We would have DISPLACED (498.76 – 22.167) = 476.59cc of fluid all over the garage floor (I'm ignoring the volume of the plug hole here). This equates to our 55.4176cc piston area, multiplied by the 86mm stroke.

If we now shave our pistons 10mm like in your example, it is true our BDC volume is greater – the piston roof is located 10mm further down the bore. But our TDC volume is greater too – as the piston roof now finishes its travel 14mm below the top of the chamber, not 4mm like before. Just as before, the piston roof has travelled 86 mm from BDC to TDC, and the DISPLACED volume is still 476.59cc. (Again, this equates to our 55.4176cc piston area, multiplied by the 86mm stroke.)

Displacement is a measure of how much working fluid can be (ideally) pumped through the chamber each stroke. And it is this that is the important parameter as it is defines how much fresh charge we can get each stroke to convert into useful work.

Hope that helps. Yours mentally,

[samphlett]

You are going to go far once you've graduated (if you do of course).

[Orion ZyGarian]

Haha this thread is awesome...

I loved the science and proofing etc.

A simple way to prove him wrong wouldve been just to say "bore x stroke"...since bore hasnt changed and the piston still travels the same distance...

[marcus]

so is that 325 actually stroked to 3.1?

[Orion ZyGarian]

You've got to wonder now, dont you? Probably just has lower compression pistons lol

I feel like i'm taking crazy pills.

Maybe once he realizes he was wrong and called all of us wrong he'll leave here and go back to turboing street cars where his only critics are high school educated and know even less then him.

One final question for XU, have you actually tried using your own math and come up with the correct displacement for known engines or are the manufacturers of every engine on the planet wrong too?

While Jason's diagram and theory is completely off and unrelated to this, David Vizard has written in one of his books how in some cases you increase effective displacement by lowering compression on a force induced engine.

It makes sense especially on supercharged engines because as long as you are effectively scavenging the chamber on the exhaust stroke, the positive pressure on intake stroke is going to want to fill the cylinder more than just what the piston displaces.

[Pete M]

Pfft... you're just ignorant, Charlie.

Browsing the site; he did install the turbo, somehow. Not exactl a smart install but it got in. The car was for sale shortly after, and he 'never had time' to get it on the dyno. But of course, it made 400+ HP. username 'BustedSpecV', so you can guess what he did to the poor car.

Holy crap, how did I miss this one, mabye because the thread name is ...

At least the guy was right about oil cooling turbos, that is true if they aren't water cooled.

But the rest is just crap, has he ever seen a piston and watch it go up and down?

You guys prob made him cry and now hes getting bad thoughts.....
