Bored and o-ringed block

Venolia low compression pistons and Pauter billet rods

Supercharger manifold with new larger blower compared to the original blower. Larger unit flows 28% more air.

Those pictures make me happy in the pants.

Rods forged?

Did you sleeve it also?

Dropped static CR ought to help life and power. Does VK have squirters for bottom of pistons? Changing oil pump, radiator, transmission build?

Good luck!

Jonsey....

jonseyq45 nailed the o-ring answer.

Rods are billet steel, factory sleeves bored out 0.5mm/0.020", low compression pistons for higher boost level. I don't think the VK have squirters built in. Oil pump is stock, radiator will be custom made and thicker. Transmission will be rebuilt for the increase in power. Two new B&M oil coolers, one for the transmission and one for the engine oil will be installed behind the fog/driving lamps, each with their own temperature activated electric fan.

Very impressive! Can't wait to see how this project goes. I'm curious how much boost you are planning as well. Any specs/goals?

Well I haven't really thought about the piston cooling as I am running an external oil cooler. I was told that I wouldn't need squirters if I have a good cooling system. I will look at the motor again and talk to my machine shop about it.

I am planning to run 15psi as my fuel management maxes out at 16psi. Lack of options on fuel management is the limiting factor or I would consider higher boost and twin turbo. No real goals other than making it reliable and quick enough to take on the AMG S65.

What are you basing your statement on? A VK45DE with 15 psi supercharged is going to put out approx. 600 hp. How much power is the S65 pushing and also how much does it weigh?

Anyway, this is an awesome project. Who wants to guess the quarter-mile times? I'm going to say below 12 secs with the full 15 psi and a proper tranny setup.

I bet at 15PSI this car will be just as fast as the MB.

Awesome project, keep us updated!

I'm counting on the weight difference

AMG S65 est curb weight: 5035 lb
Infiniti Q45 est curb weight: 3801 lb

At 8lbs on the smaller supercharger, this car was able to keep up with an 2008 BMW M6.

1994 Infiniti Q45 black on black, Tokico blues, Eibachs (I think they're Eibachs, its definitely lowered), Stillen upper control arm and FSTB, Sylvania Ultras, 18x9.5 Enkei Racing rims with Falken Ziexs 245/40/18(shoulda gotten 255s), upgraded 2 gauge ground cables, 136k miles

The S65 does the quarter mile in the low 12 second range. Yes it's a powerful car but it weighs over 5000 lbs whereas the F50 weighs in at ~ 4000 lbs. I don't think a supercharged Q45 with approx. 600 hp will have any problems with it.

It's probably safe to say you won't encounter too many of those cars and fewer still that will be willing to race you. Might have to go by the numbers, hp / 0-60 (have to beat 4.2 sec) / quarter mile (12.4 @118 mph according to C&D), etc.

Good luck!

psi doesnt mean jack, unless you know how much air mass is moved by the compressor at that pressure.

if the compressor he is using is only capable of pushing 30% more air than the engine normally consumes, its only going to make 30% more power.

to make 600hp, its going to need to flow more than twice the air.

most of the 600hp capable superchargers i'm familiar with are a fair bit larger than this one, judging by those pics of the blower.

i dont mean to rain on anyones parade, but seriously, 650hp from a blower that small?

look at the blower on the 2009 Vette ZR1. that motor makes 630hp at 10.5psi, and that blower is significantly larger than this one, and it is intercooled.

edit:

if you want an expample of a blower from a smaller benz motor, look at the M111 engine. it has a supercharger, and at 10psi, most people cant get too much more than 200whp from the motor.

nevermind the fact that it is a smaller motor compaired to a V8, but at 10psi, the blower pushed enough air to make 200whp. if someone put that supercharger on a 4.5 V8, they would surely loose power, as the blower wouldnt be able to push more air than the engine normally breaths.

you are so very wrong.

you could take a Garrett GT2860 turbocharger (this turbo flows a maximum amount of air to make 360hp), and set it up on your 4.5L. set up the wastegate to 14.7psi. you will certainly NOT make 600hp. the turbo isn't capable of flowing more than 360hp worth of air.

i have no idea how much pressure the turbo make when it flows 360hp, but it is much higher than 14.7psi (maybe 30psi?), it certainly doesnt make 600hp there either.

the same logic applies for a supercharger. there is a certain speed you can accellerate a supercharger to where it no longer flows more air than it did at a lower RPM, this is beyond its efficiancy point. this factor allows you to determine the maximum amount of air the compressor will be able to flow. most manufacturers of turbos and superchargers will tell you the max amount of power it can make.

the amount of boost pressure is not a factor. the amount of air mass it flows at a given RPM within its efficiancy range is the only thing that will tell you how much power the blower can make.

by your logic, any turbo capable of compressing air to 14.7 psi could make an engine produce 600hp, as long as it made 300hp in its normally aspirated state.

air-mass = power (potential power)
air-pressure = merely the compression needed to compress that air mass to a volume able to be forced into the engine.

Maybe you should take the time to read what I wrote first before you answer. I qualified my statement about psi with the fact that the compressor has to be sized properly for the engine. So am I still wrong?

Tho I haven't stated how much power I will be putting out, this supercharger maxes out at 970cfm or around 67lbs/min

i was responding to your bit about "double the atmospheric pressure going into an engine you will approximately double the horsepower"

yes you are still wrong about that.

i wasnt meaning to rash on you or your project. i was just saying this cause other ppl are spitting out alot of numbers with no information regarding the actual supercharger you are using.

if 970cfm is the max, you should be good for 668hp. the normal rule is 1.45cfm = 1hp (potential HP).

im not sure if youre planning for an intercooler or not. not having one is going to bring you a bit lower than that 668 'potential hp'.

i stand corrected :p i wouldnt have figured a blower of that size to be able to flow that. is that an OEM blower from a production car? or an aftermarket?

That's the main reason I never quoted how much power I was going to get, other than 15psi would be as much most cars can run on pump gas. I am running the Laminova heat exchanger air to water intercooler. The blower is fairly compact and being that it's a twin screw, it is one of the most efficient supercharger around. The unit is a Lysholm Autorotor sold thru Kenne Bell. I think there is only one or two cars that use these as OEM supercharger as they are quite expensive new compared to a roots or magnacharger.

What really counts is area under the torque curve when graphed. Why the V12 MB truck designed head engine and Audi V12 diesel do so well, the latter in spite of its RPM limitations (hence less horizontal dimension on the X axis).

I think you should school yourself before you go around saying people are wrong about a subject. All naturally aspirated engines are operating at 14.7 psi of pressure at sea level. This is the weight of the atmosphere pushing the air into the vacuum inside the cylinders. If you go up in elevation, where there is less atmospheric pressure, you will have less weight pushing the air into the cylinders hence less engine power output. This is basic engine theory.

Now, what about forced induction? I said that if you added 14.7 of boost to an engine with the correct sized compressor you would approx. double its power output. Why? Because we now have double the amount of air going into the engine. The only thing is that the compressor has to be able to support double the naturally aspirated airflow at 14.7 psi of boost. Yes, you have to take into account other variables such as heating of the air flow but the basic premise is still correct.

Here's an excerpt from an article by Popular Hotrodding:

Normally aspirated motors actually have atmospheric pressure pushing the air into the cylinders. This pressure (at sea level and at a given temperature) is 14.7 psi or one bar. Doubling the power output of the motor can be as simple as doubling the pressure to the motor. Upping the pressure to two bar (14.7 psi above atmospheric) can double the power output of your motor.

Here is where things start to get tricky. Suppose you have a 300hp normally aspirated motor and want to double the power output. If you install a turbo kit and set the waste gate to 14.7 psi, chances are you will nearly double the power output. Of course, this equation assumes a number of things, the first of which is you have a turbo capable of supplying 600 hp worth of airflow.

This pressure-to-power conversion works at elevated power levels as well, which is why we chose to increase the power output of the normally aspirated motor in the first place. If we run 14.7 psi, we essentially double any power gains applied to the normally aspirated motor. An example works well here. Suppose our test motor produced 400 hp normally aspirated. If we applied 14.7 psi to the 400hp motor, we would expect something near 800 hp. If we upped the power output of our normally aspirated motor to 450 (a gain of 50 hp), the same 14.7 psi would give us something closer to 900 hp. If we take this scenario one step further, we can see that a 500hp normally aspirated motor will produce near our magical 1,000 hp at just 14.7 psi.

And here's what ProCharger states on their website:

How much horsepower will a supercharger add to my engine?

Although some manufacturers claim a specific horsepower increase, superchargers actually add horsepower as a percentage gain (percentage of an atmosphere). Assuming an engine with a compression ratio of around 9:1 running pump gas,if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine, everything else being equal.

He also has a SVT Mustang that puts out 600+HP on racing gas. Still have to go for a ride in it.
