True. I have a a 3.9 and it is a little gas sucker but has plenty of punch!I always go for the engines with the bigger displacement, just my choice. Although you get extra horses, your gas mileage will suffer just a bit.
Thanks for the Heads up! I will check out the site. Good info to know!!To DV06LTZ I personaly am NOT a fan of K&N Filters. I had one on my 77 Impala and after about 20,000 miles I took it out and found holes about the size of a ballpoint pen tip. Those holes let dirt through the filter and into the engine. I have personaly heard of 2 other people with the same filter problem. For now I went back to the paper filter. I am looking at a different type of filter that catches more dirt yet lets the engine breathe easier also. Amsoil has a new EA Airflter that is supposed to out perform the Fram (paper filters) and K&N (wet gaus) filters.
Check out the section titled: The Absolute Facts About Air Filtration.
Just so you know, that Tornado is probably costing you horsepower.True. I have a a 3.9 and it is a little gas sucker but has plenty of punch!
Added a Tornado and seems to help a little (forcing more air into the throttle body)...K&N air filter is next.
My thoughts exactly!Just so you know, that Tornado is probably costing you horsepower.
At the very least, it is NOT gaining you anything.
Tornado, Electric SuperCharger, Oil Additives, Hotchip/Jetchip/stupid ebay chips, etc....
They are all sham products with no actual benefits.
A few years ago Hot Rod dyno'ed all the chips for the Camaro, and dumped their programming to see what the tuners had done. One big surprise was that some of the chips were blank, forcing the computer to rely on hard-coded look-up tables. What this did was set the fuel injection rich for safety. In warm weather with the engine warm, this led to an increase in HP. But for all driving conditions (like cold weather) this wasn't the best choice.The cheaper chips (ebay) do give you extra horsepower, however I wouldn't exactly trust them as you don't know how accurate the alterations are. Messing with the cars A/F ratio can cause serious damage (cough....detonation....cough) if not tuned properly.
