I'm at 385k on my daily driver.




Probably got you beat with 145.



A gas turbine doesn't use a jet engine to make power, a gas turbine is a jet engine. You can rate a jet engine any way you want to and can use its exhaust any way you want to. In an airplane (other than turboprops) they use just enough tubine to spin the compressor and fan (if applicable) and use the exhaust gas for thrust. If you need it to power something mechanically you put enough turbine in it to convert as much exhaust as possible back into mechanical energy and hook it to a gear box. It just depends on what you want. Regardless, thrust times speed is power. You can have a jet that makes 50k lbs of thrust (no need to get into static vs in flight thrust here) sitting still and it is making zero power. That same engine making the same thrust at altitude running mach 1 is cranking out 100k hp.

well, the gas turbines (LM-2500's) that the Navy uses the jet engine is disconnected from the power turbines.. so.. while it is a jet engine, what's connected to the main reduction gears isn't the jet engine portion.. just the power turbine portion..

and I've yet to see a direct comparison between thrust and hp.. it's like trying to make a formula to compare CUP to PSI when talking about ultra high pressures such as developed in a rifle cartridge..

I'm not familiar with the LM-2500, but it is probably like a lot of other engines used for similar purposes. It is likely a rework of a high bypass turbo fan with an additional turbine section (the power turbine you mentioned) added to it to converte the thrust that was formerly provided by the fan into mechanical power. In that the case, the power turbine is still a portion of the jet engine, it is just an addition. It's like taking a normally aspirated car engine and adding a blower. You still have the regular engine, but you've added something to it to make more usable power.

and I've yet to see a direct comparison between thrust and hp.. it's like trying to make a formula to compare CUP to PSI when talking about ultra high pressures such as developed in a rifle cartridge..

Like I said, it's thrust multiplied by speed. This is basically the same as a piston engine where power is torque times rpm. A unit of force multiplied by a speed gives you power. In the case of torque times speed you have to divide by a correction factor of 5252 since it is rotating. With thrust times speed you already have the proper units (ft-lb/s) and only have to convert from that to hp, which is 550 ft-lb/s.

The real trick with thrust is figuring out how much you have at any given true airspeed because a turbine that makes 50k lbs of thrust on the ground will generally make or less than that depending on speed and altitude. This can be measured, but for most people working with the aircraft the measurement is of no use. To them the only thing that matters is if the plane works like it's supposed to or not.

Oh...and CUP vs. PSI doesn't work because they aren't measuring the same thing. CUP is measuring the amount of work done. Work is force times distance. PSI is only measuring a unit of force on a specified area. To correlate the two you would have to find a way to standardize the area the pressure acts on to represent an equivalent force used to determine CUP. Then you would have to gauge the distance that the pressure and area combination is able to move a certain load before stopping. It could be done, but it would be a long tedious process that wouldn't give us anything useful.

Who gives a shit about jets. We are talking about cars.

Im sure there is someone around 1,500 hp, but the true test would be quarter mile time. But then like others have said you have the argument of what qualifies a street car vs. an all out drag car trailer queen? Can't wait for another KOS to be completed!

street car means AC/Stereo, DOT tires all around, and is driven on a regular basis and can be driven for long periods of time without the owner having a coronary

I would venture to say there is alot in the 600+ group. (I would be one) but I've seen a few TT street drivens in the 1200 hp range.

the interior cannot be gutted either I would think. many things that would have to be clarified.

Under these guidelines (damn strict ones) I'm gonna go ahead and give the award to Dan, though Wolverine claimed he could get 20 mpg on the highway at 80 and it was perfectly comfortable. He was running an absolutely ridiculous highway gear. Still though its hard for me to believe a 1200+ hp 95 GT is as civil as a 1200+ hp FGT.

my car should be finished by next friday, im looking for 1400+hp dyno runs.
