i think that i can settle this "32 extra hp in power mode" quarrel. as is clearly indicated in the following totally legit dyno chart, power mode affords the svx driver an additional boost of high-end horsepower. note that at lower rpms, power mode suffers a minor loss of power. torque graph was not avaliable because the dyno blew up when we tried to run power mode.
oh, this is with the FWD fuse in, so assume a 5% loss of horsepower when AWD is implimented. |

What is the peak HP? and at what RPM?
I'll try to drive in that range all the time. L

Sorry lwin, the scan of my totally legit dyno chart must've clipped the numbers off. in normal mode, peak HP (~170-180 at the wheels) generally comes on at about 5400rpms. The interesting thing is that in power mode, the peak power (~380hp) doesn't start to come on until about 6k rpms..

So does the dyno chart truly confirm it? Or is it just the cause of the rumor? Im confused

But anyway... 92 LSL - one of the reasons I got it was for the mysteriously faster stock track times. I think the answer to this little "mystery" exists in the computer. Or maybe oil pressure... You know how you lose power when you lose your rings. I haven't had this problem with losing power on a second "mash" but maybe it seems faster the first time because during the first "mash" the engine is just perfect and happy and all that. The second "mash" there has been a bit of friction and you are losing ponies in the mix, maybe you are loosing your compression.

A dynamometer can and will directly measure HP with a high degree of accuracy dependent only on the measurement of the electrical output of the driven dynamo. Also torque if the dynamo is as is usual arranged free to rotate against a lever and weight or calibrated spring.
But the Ò dyno Ò you pay to put your car on is usually based on a water brake and is not a dynamometer even though the title given it indicates otherwise. As Harvey has pointed out these machines can only measure torque with any degree of accuracy. The HP readings which they produce are very much subjective and calibration is always in doubt as is repetitive accuracy. On top of this all the factors and limitations in respect of a road wheel driven device further reduce the prospect of accurate readings.

92 with POWERMAD button.
My late '91 car has the POWER button on the console. Last year, I drove the car with it on all the time, and I will give you my impressions of it.
First, a little debunking. Most of you are talking about what "feels" faster, the whoaaaa factor, not measured in any meaningful way. Top gear [D4] is a ridiculously high overdrive, so talking about lockup has no relevance. The gear is for cruising in, not accelerating, and in my unhumble opinion, top gear does not "feel" fast at any time. The 4EAT box tends to learn your habits, and give you a smooth ride all the time. I hate this. I like to think I am a smooth driver. When I want speed NOW in D, the box thinks I want to go a little faster, and tries to speed up in D, not possible, or at least not too satisfying or safe. If I mash the pedal to the carpet it drops about two gears and puts on POWER mode. However, I don't actually want to be blasting off into the sunset at full roar, I merely want to accelerate past quickly and without drama. NORMAL mode does not give you this. With POWER button pressed, the car is more responsive, and does about 2 to 4 MPG less. It is also more nervous, will hunt more for the appropriate gear. NORMAL mode assumes that D4 as quickly as possible and held for a long as possible is the appropriate gear for all occasions. In the words of our esteemed Chairman, Bleeccchhhhh. Regards the extra 30 odd horses, they don't exist. However, with POWER mode on all the time, the car feels about 50 hp better, and this is logical. It will shift down quicker to a low gear, and hold it longer. What you are getting is power to the road when you want it from the meaty part of the rev range, i.e. between 3 and 5 thou in 3 range or 2 range. The car feels lots lots faster. One other thing the permanent POWER mode did, it allowed me to preselect 3 by dabbing the pedal when about to overtake. In NORMAL mode with the present tranny I have, nothing short of carpet bashing will produce a lower gear. Joe

John, are you talking about the "IRIS," as seen in this cutaway? (Iris is the large gold "disc" at front of top of engine)

Yeah that's the baby, the inductor valve. They SM also referes to it as the 'Supercharging Valve". Section 2-7 of the manual has a description of how it improves the volumetric efficiency of the engine, how more air gets into the engine. It's a pretty neat feature on the SVX. I am thinking that it doesn't always do it's thing in the low rpm zone but hey no proof. There isn't any detail on when it opens and closes relative to throttle position. It is very interesting.
