Tune model vararam or Roto-Fab ?

Vs.


Vararam and whatever that can be added to it.





what im after is something that makes me feel the difference. and since there was an issue about vararam having problems, its holding be back, BUT its the ones that i could easily lay my hands on quick since its available !!

I might have to wait for the roto-fab a couple of weeks

Based precisely on the choices you have given, I would go with this.
ADM scoop, VMax CNC throttle body, and Roto-Fab. I believe you will feel and like the difference.

You can see the feel part of the VR in the dyno above. Notice the torque difference right as you hit around 2500 rpm versus stock.

I hope to dyno a similar setup like you described this weekend. Unfortunately the pulls will like be at a different location, so comparing to the above dynos won't be an exact comparison.


Bottom line, as you've noticed, is that most people will recommend the one they bought. The good news is you, like most, will decide on one, buy it, and be perfectly content. And that is great. Pick one and have fun.

Same day within minutes of each other. He did do SAE too and the numbers were slightly lower on both, but the spread was about the same.

SAE is only relevant when you want to compare numbers across the country or on different days. In this case BOTH were STD and were within minutes on the same day. The SAE correction wouldn't make a difference in the spread.

Weather changes still occur. As you can see on the bottom of the dyno sheet.

~-5* temperature change, raised barametric pressure, ~7% increase in humidty, blah blah blah

Not enough to matter. Like I said I had him do the SAE and the spread was the same.
This was the first time I ever bothered to take one of my cars to have it dynoed. The shop told me that nearly everyone uses STD so that's what I went with. I assume this is all math formulas and since you know so much about this stuff you can do the calculations and post what SAE would have been. Wonder if you will find 10-15 hp difference by playing with the numbers?

Will it be enough to matter? imo no, but the arguement is over something stupid, "which cold air intake is better?", in which people think the 2 or 3 rwhp difference between cold air intakes is a life threatening situation, then apparently that one or two hp difference means A LOT. so then you have to nickel and dime everything.

Exactly !!.. Thx alot man

In the end, I wont learn alot about the difference between them unless i try.

So if the first choice was good, then thats great if not i'll just change

Thats why i posted my question.

I wanted to know if there was a noticeable difference, apparently there isn't that much of a difference if both parts were tuned properly. maybe it changes from car to car but that i will have to find out.

While i'll agree that if we were talking about 2-3whp difference there wouldn't be an issue. The problem is, we have a few CAI companies advertising gains ranging from 20-40whp and 25-45tq with just the addition of their CAI. Hell, people are still quoting advertised Typhoon increases as 18/18 when we all know they don't put down half that. Is there a HUGE difference between CAI's, absolutely not. Is there a difference, absolutely yes. The price of most CAI's is between $250-$350 (not on sale). Would you rather pay $250 for a CAI that puts out 4-8whp or $350 for 12-15? That's what it comes down to.

I'm cheap..... I'd buy which ever one was on sale first.

HAHA. Now that I can understand.

I could take a quote from all the ebay header threads. Why would you put a cheap (insert part here) on a highend $35k car, . Since I don't live by those rules, nor do I think the Camaro is highend, I won't.
