Z1 Tubes and breathers installed...

^this. Roddy, best not to give advice about stuff you have no idea about.. don't guess, search. They give real gains. I had them as my first mod. IMO, worth it compared to the price of the G3s.

Take a breather. I've done a ton of research and its not my first go fast car. I went with K&N drop ins based on the research I did, which showed that there was not much to gain above and beyond by going with the G3 intakes (especially looking at dollar value). As for the smooth post MAF tubes, like I said there is maybe 1hp to gained from those alone. Personally I don't have them. The dyno sheets I saw showed about a 5hp gain from the K&N's and post MAF tubes, and 8-9hp from the Stillen G3's. The Stock intake flows quite nicely from the threads I read. The biggest gain in the K&N drop in Post MAF mod is the filters. I stand by my 1hp gain from the tubes alone. Most guys who had the K&N's first then later added the Post MAF tubes didn't feel much if any difference compared to the stock tubes. You ok now? While I may be new to this forum, and the VHQ, I do know what I'm talking about.

So you don't have them and don't have a dyno with just filters. But according to your research they don't really help and you back up your statement by concluding because other guys 'didn't feel a difference', there's only a 1whp gain?

Thank you for explaining.

Roddy1

Ya, did you dyno post MAF tubes alone? I don't think anyone has.

Thanks for clarifying....

I'm not saying I have the final answer there big guy, but I've done the research. Other poster is on about not knowing what I speak of. I dont have the first hand experience on my car , but atleast I've researched. And rode in a 370 before and after the owner installed the post MAF tubes where we concluded its likely more for looks than power. Should I up my estimate to 2hp? can you even feel that kind of a gain?

I wasn't arguing that Post MAF tubes only had a 1whp gain. You were. So please, do explain what I need to clarify. Your argument is broken and opinionated. You state 'facts' and then back it up with speculation and your butt dyno.

Roddy1

Do you talk to people like this in person? You state my Arguement is broken... what arguement... I stated an opinion that someone interpreted as fact and I'm clarifying what I have researched and experienced.

I'm saying I figure the smooth tubes are worth 1hp... or maybe 2hp. This isnt rocket science. They are the same diameter and length as the stock tubes. I ran a Yella Terra smooth tube on my LSX at one point with no noticeable gains, I have been in a 370z where smooth tubes were installed and there was no noticeable change either, I've talked to other Z owners with the same experience.....

Are we good now? My comment was stock tubes vs smooth tubes are a 1-2hp difference, and I said I wasnt going to bother installing them....
