yep, that’s one of many... good find... I had to scroll through to find the actual results... they start on post #230.

This was in 2005... you see what I mean about not being able to just poof, make it appear on a request. There are lots out there. The people that are skeptical have a right to be so. It's up to each individual to trust that what is said comes from being at events like that one and knowing the people that were at those events... it's not all "talk".

I realize that mods that are 2 & 3 years old don’t have as much recent data that is easy to find - because it's all been hashed out long ago. Some stuff doesn’t work and that has been proven too... there are soooo many configurations that do and don’t work that there simply is no 1 answer - other than some indeed do. Everything in my sig has worked very well for me on dyno and track – none of it was on a whim or by someone telling me to put it on my car… I did sh!tloads of research and saw what does and doesn’t work from data sheets and dyno days and cars that do well on track, etc... and some from just personal testing… doesn’t mean I think everyone should have the same thing... WaLLy has a coupe with similar type mods but some are different manufacturers - for the coupe they work well... his current configuration is definitely comparable to my cars ability... he is the coupe in the vid - but last time we raced at Irwindale (1/8th mile) he was edging me out in most runs... And that was after a few added mods - so just that alone is viable statistics that show bolt-ons work.

Anyway, you are on the right track! Good luck, happy modding!

 

This link has a few nice chart. The best one I found so far:
http://motordyneengineering.com/dynos.htm

Hope these charts were done in good control environment.

 

^k so i dont really know how to read dynos that well but did the 5/16 do the best?

 

Generally (most dynos that I have seen and others have documented) the 5/16" shows slightly better gains mid range... the 1/2" slightly more top end.

Honestly I think the difference would be so small with daily driving and even tracking that one can't really be declared better than the other.

Many people prefer the 5/16" over 1/2" because it allows more clearance (strut bars, engine covers)... they also like the “slightly better gains” in the usable power band… Like I said it’s doubtful you can tell a difference while driving, but I haven’t slapped them both on so I don’t know for sure.

 

Here's another one. sorry for annoying everyone for posting piece by piece:
https://g35driver.com/forums/showthr...t=wheel+spacer

 

I am also considering in intake...maybe the K&N intake...maybe the borla exhaust or stillen exhaust (haven't decided) and a plenum spacer.

I have gone the modification route before, and when I have, I have always dynoed after a mod to see where I am.

If you have dynoed your car and you have hard numbers you can post, great...otherwise, if you are just guessing and assuming, it is really useless.

I would really like to know how much rear wheel horesepowr was gained by adding an intake, exhaust, penum spacer, etc...each by itself or any combination of these things.

This would really be of help and much appreciated.

Thanks!

 

You're supposed to research on your own and find the dyno sheets that someone already posted.

 

LOL!!! Telling OCG that he has no basis is down right wrong. He has been one of the most informed people on this forum. I suggest you listen to what he is telling you or just leave. I assume you use to have a Maxima. You maybe part of the Nissan community, but the Max is not a G/Z. I use to own 4 Maximas.

 

You know whats interesting, the nay sayers seem to come from the Maxima crowd.

 

^+1 like everyone has said 100x.

 

yep, I noticed that too

 

I was being somewhat sarcastic Russitcle. You're the other guy that would argue for days on end vs digging around your own very posts. Even at the risk of actually taking less time, being more informative or proving the other guy wrong. To ME, that doesn't make alot of sense. I usually try to save a portion of my own posts so they can be pulled up later when someone asks. Especially if they contain valuable info.

On maxima.org, important/informative posts are sticked and organized. Here, picture and video threads are deemed more important.

 

opcorn:

 

Suggestion to anyone reading this thread... re-read the original post. That post has been responded to and answered and the OP seems content with the info given... why do the same 2 or 3 negatrons always find their way into these subjects? And why are you perpetuating something that doesn’t have any regard to the OP???

If this information is so important to you - why don't you start a thread and ask away... Why do you 2-3 (and you know who you are, so does everyone else) look for threads to butt into and cause trouble?

Now - all you nay-sayers.... YOU prove to ME that these mods don't work. Sounds pretty f-ing stupid doesn’t it… Now you know how we feel…

Vlad, share that popcorn bro... all the crapolla "theories" are gonna start posting...

 

wow!!! maxima.org sounds great!!!! way better than here... why are you here not there?
