Vararam web site is updated

The new page is up and this is from it.

Quote:
We plumbed directly into the intake manifold in order to give you a true intake
manifold plenum temperature reading from inside the plenum itself.



During this test ambient temperature was 79-82 deg F.

What you will notice in the EFI logs is that the VR system dropped the intake plenum temps 20 deg BELOW ambient tempuature at Wide open throttle from 0 to 60 mph. At cruise 30-40mph we averaged about 3-4 deg below ambient temps
You will also notice the manifold pressure of this "No Tune" restricted system 14.8 VS 14.6 for stock.
The MAF flow rates rose from 42.43 grams per second on the dyno to a whopping 55 grams per second on the road, same car same day just after the car was taken off the dyno.

That's a density altitude change of -1,250 feet and a flow increase of over 20% on a 0-60mph run alone. You will never see any of this on the dyno, so we data logged it for the world to see. (no claims, just facts) Thats over a 4% increase in HP and Torque on top of your dyno gains from a density change alone!

This is why at Vararam we never really care about peak dyno numbers,
we develop our systems on the track and road.
Our systems are Engineered for the real world!
In the new Camaro system we designed a broad power curve into the system to make sure the new Camaro unit would also dominate the dyno-drags as well.

Here are the logs from EFI Live


With VR plumbed into the plenum

I'm still very excited to see the final numbers and can't wait to get mine, BUT ....

I haven't seen many fully stock camaros put down the numbers they are showing.

"Example #1 - 2010 6speed SS with a VR 398 rear wheel hp and 401 Torque simply add 4-5% to both = 417 rear wheel hp, 421 Torque (stock car pulled 382hp / 378 Ft.lbs.) "

what's the big deal? Every dyno is different, I've seen stock #'s both higher and lower.

glad the info is up for everything to see (and all the non-believers to dispute). Once some of the pre-orders get bolted on we'll see all the positive reviews.

Like I said, I'm excited also, the % is going to be the same roughly regardless of the stock dyno numbers. I was just curious who has seen numbers that high on a stock LS3 M6

Yes "Me" and "POWERFREAK" and "TAG UR IT" you can find a lot of info if you do a Search on this site.

i hear yeah...I think Jannetty had stock LS3's even higher. The important # is the gain

I do believe it's impossible to decrease ambient temp in real world conditions unless you are using a heated element. Then, all you are really measuring air flow.

TAG UR IT is a post production unit, But from my calls to them, All the units will be made the way that is best for your car, If you have a A6 and have no mods you will get it one way and if you have a M6 full of mods it will come with some changed parts, This si on the no tune units.

I've refrained from saying it elsewhere...but Vararam really let me down. I spoke with Patrick several times (each call was one hour or more) and I was supposed to get a beta unit for the tune version. I didn't want to pester him as he was in development, but I was assured they had me accounted for...I was even willing to send them my LMR setup so they could do a competitive review (after I had done a before and after once receiving the vararam intake).

I know that you've been a promoter and apologist for vararam, perhaps your more aggressive in your contact with Patrick...but I just really felt a little 'jilted'. I will likely get the Vararam in the future, and have it back in the shop to re-tune (which requires a 400 mile drive)...but the whole experience is leaving me a bit disappointed. Great products take time...great communication and customer service is EASY...especially for smaller companies that can control their message.

Sorry that this got "lost" in all the ongoing testing and development we were doing!!! No intention to not communicate and ignore !! We have been head over heels with this Camaro project and been burning a lot of "midnite oil"! Patrick's forte is in the development and testing of units !!! Call me at 866-507-2648 and we will make things right and show you we do care about customer service!!
Thanks
Steve

Do you have the time to do your own testing, I do not but that was done by them, I believe that Vararam did the testing and told us the results, May be one of the shops on this forum can do this test if you don't want too.

Hi i am bit disappointed for you, But if its a big company or one man army things happen, But the test if you will is how they fix it and i think you will see them make it right by you.

So dos that mean i cant say any more about all the other manufactures that i like, Hope not or this will be a vary empty forum.
