I've read a bit about them, and they really seem to do what they say. i'm not sure if the butt-dyno will notice it or not. like I mentioned above, the frontier and xterra guys all seem to love them and list them as a great bang for your buck, must-have modcgray wrote:I am skeptical that it makes any noticeable difference. Let us know what you think of it.
right. this is where the benefit lies. particularly when driving a big heavy truck. we're not talking about redlining a 370z on the track, we're talking about driving around town and towing a trailer. I expect a better throttle response. if you check out the website, he has a dyno chart up which shows a nice increase in midrange torque.HLEGuitars wrote:
Adding the spacer alone did ALTER the HP and Torque curves, especially in the mid range..
thus
there was a noticeable improvement in throttle response with the spacer alone added when driving the car, both in traffic and on the track, presumably from the decreased heat transfer as well as the increased runner length
The one from gray at xtp is machined from a single piece of aluminum. They're beautiful. And they are the preferred ims on the frontier and xterra forums. You can do a little searching on those forums, but people don't seem to like those other ones.oreogaborio wrote:geez.. the one from extremetruckperformance is 265 bucks?
Just found this one for 150
