I went to DYNO day for diesel trucks. The trucks were pumping out 900-1100HP. They suck a lot of air when running full throttle. We tested a truck with a KN airtube and filter and the same truck with a stock filter and tube and finally with no tube and filter. There was no gain in HP.

Are you here to contribute to the forum or simply to advertise your wares? If it is the later than you may want to speak with one of the mods regarding your desire to do so.

Regarding the NEW diesel trucks (particularly the GM Duramax systems) this information is correct but regarding nearly any other high HP application, the addition of a high flow intake system has been proven to increase HP due to intake and/or air filter restrictions. I've ran and participated in a large number of dyno day events and have seen this personally. My knowledge on diesels is more limited but my roomate runs a 2006 GMC Duramax and I get the diesel specific info from him as he has been a hard core race addict for quite some time with a stable of high HP vehicles.

I highly doubt that. Far more likely is that you're confusing lb-ft of torque with horsepower.

Aye, generally speaking 900+hp daily driven diesels are fairly rare but some hit the numbers. I used to street race back in the day and an associated friend, Adam Winslet, now toys with diesels and gets into that kind of HP range. Here is a listing of the results of a dyno day back in '05 here in Sacramento. I think THIS is the 8

00HP dyno video

Hey guys,
I want to get a K&N filter because they are great and last forever. I've had one on my old buick GN for about 90k miles. I'm not expecting to pick up any hp or mpg, I just hate buying a new filter every 4-5 months. But will the added air flow confuse the MAF? I've heard quirky things like this can happen to modded Toyotas, but my source was a dealer service advisor. Anybody using a K&N on a stock Prius?

RAKIMB17 - yep, i believe that some of the toyota reps do say that the K&N air filters DO confuse and contaminate the sensors. I do recommend that you stay within the factory parameters, yeah its a bit of a pain to replace them, but i think it's relatively easy to do so on our prius's.

I recognize your GN as an awesome car, my friend has a completely restored GNX, and that is a BEAST! We might race against each other, but i have a feeling that he might take me if i dont SQUEEZE! NO, not the prius, my 96 Grand Sport.

that's my 2 cents and YES, i am running a K&N filter on my 96.

cheers

There are a few Prius with K&N air filters. The engine performance and fuel economy are not improved, but there is a potential savings in terms of paper filter replacement

In the 2001-2003 model the air filter is directly over the MAF, so it is important to re-oil *lightly* after cleaning to avoid oil drips onto the MAF. In the new model Prius the engine air filter is relocated, so this may be less of a concern.

On all Prius (or, all cars) there is the potential for the K&N to pass more particles. It seems wise to perform used engine oil analyses and keep ttrack of silicon. If that goes high, we can be pretty sure that the K&N is not right for you.

Thanks,
A GNX? Put that baby away for a few more years. It'll be pushing $60-$70k. I wouldn't race him. Your GS is FWD? If your buddy has a true GNX then he has a ladder bar that helps him put more power to the pavement. If he will give you 3 car legnths then maybe you can take him.
And don't squeeze, BOOST!
