Vararam CAI Testing on Dyno at England Green Racing (Pix, Vids, RESULTS!!!)

[GMRULZ]

Very nice guys! It put down what I expected for the most part.

I expected it would be worth about 15rwhp on the dyno peak. I didn`t expect it to change the a/f ratio as much as it did. As Ted suggested it is the equivelant almost of getting an a/f tune. Going from 11.67-12.3 a diff of
.7 a/f and is probably worth 8-10rwhp. So 15rwhp from the additional flow and 10rwhp from essentially an A/F only tune. 12.5-12.7 seems to be ideal on our cars to most tuners where they find the most power w/ basic bolt-ons. I lost horsepower and torque at an A/F of 13.0 vs 12.7 w/ more timing. The great news is this intake is really flowing some air. So a tune at TAG`s 12.3 a/f is not going to net much more, probably 3-6rwhp since the a/f is almost optimal.

All in all a great product, one I was planning on getting, got tired of waiting and since I will be going w/ a Whipple probably was a wise choice to go with the one I did.

I hear ya`ll on the ram air effect, not sure I`m buying that it increases pressure, but it certianly provides a steady stream of cool air.

So here`s my challenge to ya`ll, anyone w/ the Vararam, Headers w/ any exhaust and a tune only (no more mods) on stock Pzero tires, see if you can beat my Non Ram Aired ADM Race Intake, 1 7/8 AR Header w/ cats stock muffler, tuned car on street tires... Until ya`ll can do that, I`m not buying the ram air effect. Sorry guys. Cold air, and a lot of it, heck yeah...Ram air not so much...

So the big question, when will everyone else get their Vararam? I guess Christmas just wasn't in the cards for most of us.

Ill take that challenge if thats the CAI i go with! My car (altitude corrected) ran a 12.43 with just a K@N air filter at 500ft above sea level track. I need some of your -648 air In Illinois!!!

Sounds good! No corrected numbers though, the challenge is what you actually run. Come on down sometime, we can put you up for the weekend and you can head to a track rental with our group. 6 hours side by side racing, good track prep and good air all at 105 bucks what more could you ask for!

Price???

I dont like corrected numbers either but when our cars are running in 2000ft of air difference its the only way to balance it out. I also corrected your time it was a 12.28 at that track elevation. Thanks for the invite but VA. thats a long ways off for me. Ill be at camaro fest though. You coming?

So in essense the car is being tuned in that respect Via MAF Fooling.

What do we do to find power in a tune? We Clean up the A/F and advance timing.

LS3s with Headers and a Tune put down 410 RWHP with Stock air box and 420 with Most Aftermarket Air intake systems so your right in line with everyone else.

So How much of the power came form actual air flow and how much of the power came from MAF error?

I would say a 50-50 split

Were did the 6 HP and 4 lb torque go on the last pull, I think I know, Computer learning out Knock from too much timing due to maf error.

Ted.

Ted,
I may be wrong about this, but where you were talking about fooling the MAF and the last pull being less HP: Were you saying that the PCM is changing the long term fuel trims after it "learns" what the O2 sensors are reading? Which would be correcting the MAF error over time?

I may be way off base there, but if I am right, then I dont think people took your post exactly how you meant it.

Anytime the MAF is moved, relocated ,resized or reshaped the entire curve will be changed and the entire system must be rescaled vs OEM to keep it within tolerance.
The Term "Tricking the meter" is not an accurate statement because any good design will follow OEM tolerance regardless of MAF location size or shape. That is just one aspect of how a proper induction system is designed.
This is not an overnight process it takes time and thousands of miles of testing.
This is what we have spent our time doing with A6 and 6sp manual cars.


(There was no Knock of any kind and there has not been on any car in testing.)
As for power delivered more with headers less without etc... the setup you see is beyond conservative, you could run 89 Octane fuel through it and we have without any knock in 100 deg Texas weather.

because it is so conservative I know that we can easily pull another 5hp and 6-7 ftlbs out of it and even that will still be conservative.

(Filter Flow)The Filters height of 3.0inch is a none issue ,this is for another reason that you will see listed on our site later when it goes live.
( filters are 1400-2000CFM)


Heres the thing guys, This is one of the lowest Before and after Dyno numbers for a 6sp Man that we have on file!
(His Torque gain was low)
We wanted to start him off soft to verify where the car was ,then turn it up, turns out we had alot left.

Due to the Camaros weight ( 3,800lbs)The system is designed to produce greater Torque than HP gains.
There are many features that make that happen but one was to give up peak HP and concentrate on 4500-5500RPM rather than a 5500-5800RPM peak numbers.
Our goal was to build a broad fat power curve ,as an Engine development Engineer who specializes in induction system design, I pride myself on it.
This is a Tuned Induction system, not a cone with a pipe!
Peak numbers will never make for a quick car at 3,800lbs!

We could easily custom tune this car for another 10-15HP even after we lean on it from the numbers listed.

If peak numbers are all that is wanted ....thats easy ,We can switch the aero package around back to our original prototype combination and gain another 6-8hp but we will lose Our broad power curve and the car will not be any quicker.


WE will gain more from each kit ,once the car is on the move from the Ram Effect ,which we limited in the design of the system for a specific gain in flow resulting in a drop in D/A inside the plenum of the intake manifold.

Best Regards VR Tech

I fully respect what you are doing, and I appreciate you addressing my questions in a professional manner.

We may have a difference of opinion what certain data means.

Above in red are 2 things I would like to address.

OEM tolerances are + or - 5%

I find it very hard to believe there was No Knock Value what so ever, I dyno tune thousands of cars and .5-2 degrees of Knock retard is Normal on completely stock vehicles and quite common, the Stradegy in the computer is designed to keep the engine right on the edge of detonation all the time because this is where the best power is availalbe.

Above I mentioned this, When the MAF reports Less Air then Actual 2 Things Happen, The A/F is leaned and the Timing is advanced.
This is immediately appearent in the data logs and shows up as fuel trims +, I will repeat if the Maf Reports less then actual air flow, Less fuel is added, the O2 sensors see the (maf Error) adds the necessary fuel and we see this as + % fuel trim., NOTE fuel trim is only active during Closed Loop, When you go to WOT it Relies on the MAF Report to add appropriate fuel.

The Computer Power Enrichment Table is Commanding 11.4 but Getting 12.4 that is about a 10% less than actual MAF Reported air Calculation.

The second layer is Engine Load Calculation, and Grams Per cylinder Air.
Less MAF reported, calculates as Less Load Value, our Timing Map is RPM and Load Referenced with less load Extra Timing is Added accordingly.

With all this said, I can't wait to try one, You have the Best warranty in the business and this speaks volumes.

Long term Fuel trims DO NOT change the MAF curve, Short term fuel trims are immediate, and learned values are Long Term fuel trims, this only affects Closed Loop Operation where we are running at 14.68, Idle or Light throttle Cruise.

As soon as you go to WOT or switch to the Power Enrichment table your Running Directly off of the Maf, and if it reports less air you get less fuel and vise versa.

The reason the fuel trims are there is to protect the engine in the event of a faulty sensor, whether it is an Air Temp, Water Temp, MAF, TPS etc.

Maf also Get Dirty and Report Less air then actual. we clean them and fuel trims return to normal.

Ted.

WOW!
There is much more in this than just smooth air. Too bad I'm in Kentucky as I have a V6 with Stainless Works Long Tube Headers and exhaust and am on the list. Would have love to let y'all play with the 6 and see what you can do with my set up.

I know, it is the best one can do to try and figure da diff, however I used a calculator and put in my rwhp and raceweight, it told me on a zero da day the car would run 12.7, w/ the air we had it would have been no better than 12.6 for the diff in da. So the calculator was off 4 tenths... Still better than nothing though.

Your welcome on the invite, if you change your mind just let me know.

Still unsure on the Fest. :(

Take it easy man.

[Robert_K]

Nice meeting you Doug. Very nice Camaro you own too.

[TAG UR IT]

Well, thank you very much, sir! It was a pleasure meeting you and the others as well.

Hope I'm able to get back over there later in the week with the production unit on hand. Put down a couple more dyno runs to see how it performs over the test unit I have now.

[sales@vararam.com]

We will begin sending more PM's next week asking for information about your vehicle(Auto,stick,exhaust,etc) and shipping and payment info! Also we will need to know if you want the "No Tune" (doesn't need tuning immediately but can be tuned at a later time) or the "Tune (500plus HP vehicles -heavily modded - requiring a tune upon install) version.We have made a minor "tweak" to the filter for the "NO Tune" models and Green Filter will be processing this change and shipping filters to us next week.
Thanks
Steve
