When you anyway wasted your old block I'd watch out for the 1G-GTE, 2JZ or anything. :winky:

:tsktsk: Have you been running on stock internals or have already fitted the forged ones?? :o

AH C B) B) L! Never saw something like that.

External Wastegate??

No.... or do you think in 5th gear (1:1) you don't have any loss any more?? ← Hi, the dyno actually measures force at the rear wheels, and the speed. In scientific units (Newton, metres per second) the force*speed equals power in Watt. Force can be related to the torque (wheel size + gearing into the equation) and speed to rpm in a similar way. Hence torque*rpm (in scientific units, Nm and rad/s) equals power in Watt. The reason the measurement takes place in a certain gear is the 1:1 ratio in te gearbox, which assumes the least amount of drivetrain loss. For the IS200 this is 5th gear. Also, preferably a high gear is selected to have minimal wheel force to prevent slip, which makes the measurement inaccurate. How do they estimate the drivetrain loss? Some do it like so: When making a dyno run the wheel power is measured. At the top rpm they depress the clutch and measure how quickly the drivetrain decelerates. The quicker it decelerates, the more drag it has and the more power it saps from the engine. This power (estimate!) is added to the wheel power to obtain the crank power. Drive train losses aside, the gear in which the measurement takes place does not matter. In 4th the measured force will be higher, but the speed lower than in 5th, theoretically giving the same power. So, like Roadrash already indicated, you cannot multiply the 4th gear power measurement to extrapolate it to 5th gear by the difference in ratio. It is merely a question of how much drag the gearbox has in 4th compared to 5th. This difference would be quite small, imho. The only way to find out is to redo a run in 5th gear. Cheers, RX-Men-8 ← Amen! :)

I think this is the problem. Caused by standing on the brake for a long time, downhill, maybe heavy weight in the trunk and in high gear. So the discs can heat up as h*ll and change their shape during cooling.

Somewhere between 350-400 hp... ← In 4th or in 5th gear......

No.... or do you think in 5th gear (1:1) you don't have any loss any more??

I know, but I need to know the flywheel bhp... So whats the ratio/conversion factor? ← If I am correct, the IS200 in 5th gear has a 1:1 ratio. ← YEP! :winky:

BOAH! This looks awsome.... somebody knows his Job!!! B)

HAHA!! Seems to get funny!! :D Which engine do you have in there already? 3S?? Or do you plan to boost up the 1G? B)

I only hope you don't connect the FPR to the stock fuel system.

Yes! :D New guessing game: Do you think I read your first post very exactly You won't need a thicker head gasket when you set the CR down with the pistons. B)

I think I don't get it, what do you mean? ← Let's play a guessing game.... Would your engine run with only the rods?? :D

they are maxed out :winky: ← Yep. Not alot more to get out of the standard engine without doing internals and injectors etc ← The boost drop doesn't depend on the fuel feed. Check your wastegate! :)

N-ICE! :winky: And what about the Others??

Check the duty cycle setting on your BC ;)

Nothing.... don't have trouble with it... :)

I also got trapped 3 times in one week!! :tsktsk:

I had mine 8 steps away from hard..... this was like driving on steel rims without suspension.... :duh: As I went to JAE (long highway drive ) I set it softer... to 5-8 steps away from soft. Now it feels very good.... I think steps 20-30 (hard) is for drifting not for driving...

PERFECT! B) Glad to see it at JAE!

Mine is running on higher fuel pressure and it doesn't run richer because of this. ;) Of course... after an ECU reset it would run richer, but it will learn to set the correct Lambda and after some miles of driving it's fine. :)

What are you going to use to control the fuelling (e.g. "ecu-wise")? If you just change to bigger injectors and do not alter the fuelling maps, your going to end up with sh*te idling, because the injectors will be "open" for the same amount of time but due to larger capasity they inject much more fuel. That leads to the mixture being waaaay too rich when idling. ← ..... yes and the ECU will check the rich mixture over the O2 sensors and will reduce injector opening time to get L1 again. ;)

Yes not wrong, but we talked about " :o Weakness or not Weakness ". And in my opinion the IS gearbox isn't weak.... far too short. It's strong enough to handle more than the doubled power. :) Gearboxes are robust and strong at all, the most expensive part in a car. The clutch should be changed also on supercharged IS'es. ;)

Your point here is? ^^That's exactly what I got. With only 5 cyls. But your IS wouldn't have stock 155HP with only 5 Cyls. So it would be somewhere 130HP * 1.7 = 221HP or anything... :shutit: But it's OK! :winky:
