What makes the difference?

Here I am yesterday driving the toll road home from work going about 60 -65 MPH. I come upon a merge point, traffice is fairly heavy behind and next to me but I left my usual space in front. The driver merging isn't speeding up or slowing down, just pacing me <idiot>. Now I need to speed up and SOON. I press the accelorator down about 3/4+ and it starts to speed up then SNAP! power mode kicks in and I take off like lightning. I think it even surprised the SVX!

I adjusted my TPS some time ago so it takes less pedal to downshift and/or go into power mode. What I don't understand is why is it sometimes like a rocket and others it just accelerates nicely in power mode? I've NEVER had it perform like it did yesterday.

Any ideas?

Yes I do

You have the special 92 SVX that sometimes has an "extra 37 horsepower" (searchable). Other doubt it but your a believer now.

Or here.

i have definitly felt this in my 92. what an incredible feeling!!!!

Food for though on this topic... I noticed that my power mode doesn't make that much of a difference in warmer and hot weathered air. However, it seems to make a huge difference in the colder seasons...Anyone notice this, or am I just nutso? Again, Not too sure if overall driving altitude would make a difference either??

I own a 92 lsl, any chance that we can prove this on a dyno and it the extra 37+ in power mode on top of the 230?

Thats a joke right?

Well, if all youse guys & gals don't know I guess I'll never know. I'll just have to be better prepared the next ime it happens.

I don't feel quite so bad now that I can't figure it out.

Yes I think the effect is less when it's hot out.

You mean the extra 37 Horse Power? or the dyno test?
It's so random the dyno will never find it.

Can a dyno test be run with the throttle just punched? or does the acceleration have to be done more slowly?

[Subafreak]

The 37 horse. I think you can just smash it on the dyno.

[chris92svxlsl]

maybe we should kidnap the lead engineer who designed the svx motor, Im sure people would pay $$$$ for his knowledge, on this site. We can make a calendar to see who gets him when. LOL!!!!

yes, i actually settled this argument once and for all with my totally legit dyno chart, as seen here:

Can you revise that chart to show the gain by adding a yellow sticker and a Type R badge? I've been thinking of adding them, but I want to see what results it would have on the dyno. Thanks
