You ran 'a smooth tube on an LSX' and rode in a homies car with a 'smooth tube mod too', and you didn't tell a butt dyno difference from the last time you rode in it.. So by the internetz you've read you came to your conclusion.. Hm

Well if you internet tough guys are done...

We actually did a MAF tube dyno test and there was a 1HP delta. Repeatable.

It was, however, noticeably louder.

Good to know. Do you have a link to the dyno, by chance?

Weird how yours was louder, I didn't notice any sound change.

I didn't keep them, it was just for a "lets see what this does" thing, put my actual cold air intakes on immediately following that test.

It was louder on the dyno with the hood open standing right next to it, dunno what it would be like on the road.

Lol. Going for a ride in your buddy's car and doing your own super sweet research is nice and all, but fact is, drop ins and tubes makes good power and its cheap. How do you figure they dont flow much better? Or that they make maybe a 1hp difference? Just sayin, there's enough crap to weed through on here when trying to find real world answers

Holy crap.

I'm saying the gains are mostly in the filters. Stock intake is very good. post maf tubes account for maybe 1-2 hp of the TOTAL gains from doing the "Drop ins with Post Maf tube mod"

How do I figure? There is No change in length or diameter of tubes. Only smoother. Thats how I figure.

Clear?

I'm guessing that the 1hp gain was in the 6000-7500 rpm range? Was there any gain in the mid range rpm's?

All times are GMT -5. The time now is 04:00 PM.
