HI SPEED LEAN OUT--DO I NEED ONE?

<< < (2/3) > >>

The best answer is.....It depends

If you've ever dyno'd an engine with and without the hi speed, you'd be impressed with what you can get. May not apply to all combinations, but you might be surprised. Very easy to figure out the hi speed on the engine dyno.

George:
I found the dyno to be an interesting way to break in an engine. I never found the dyno results on the track. I was told by a few racers the dyno will load the motor harder than the track. I believe if I could spend days playing on the dyno there might be a gain in tuning knowledge. Just my 2 cts.

wideopen231:
Worlds best and most accurate dyno is 660 or 1320 feet long. I have had guys that dynoed motor picked up power and slowed down on track. Maybe the load. I do agree it can teach you few things,just not to live or die by.

 I have always just made change(1 at a time) and recorded effect it had on track  of coarse conditions come into play. With high speed its easy to A-B-A test.

dreracecar:
In head to head competition, I have never seen a dyno win a drag race yet

fuel749:
The dyno is just like the computer....the information it gives you is up to the user to figure out if the info is good or bad and how to use it. Higher horsepower doesn't always equal higher performance. And making dyno pulls isn't just about getting the highest number, it's about gaining information. Sometimes it's different info than can be learned on the track that you can combine with your on track info to be a better competitor in your class.

As far as a hi speed is concerned, I'll stand by my original answer because it depends on to many variables.
