Hey guys, I stumbled on this while on ebay searching for a good intake system, is this a good deal? claims up to 40 HP gain, thanks

Save your money - I had one on my car for a few weeks and the surging drove me nuts. I then swapped it out for the stock unit one night at the track in between runs and picked up a whopping .04 seconds.

40HP? Puuuhhhhleeaassseee......

 

I HAVE IT ON MY 07 Z51 AND IT IS GREAT

YOU HEAR IT SUCK UP THE AIR WHEN YOU ARE ACCELERATING

NO SURGE PROBLEMS.....

LOOKS GREAT AND WORKS GREAT

GO FOR IT AND GET IT

BUY IT NEW FROM BREATHLESS FOR A FEW BUCKS MORE....... AROUND $515.00

 

$500 to pick up .04 seconds, wow what a smokin' deal that is!

 

Hope that's a typo....because .04 is nothing thru the 1/4. But .4 is really good. So which one is it.
I bought the Vortex Intake from a forum member for $275.00 used. Took the VaraRam off. But I haven't redynoed the car yet. I would say that Vortex is a little smoother at idle. SOTP is about the same.

 

Nope, that absolutely wasn't a typo - .04 seconds, aka 4/100ths, aka four one-hundredths.

Something a lot of people don't realize is that GM does actually does things right, even with stock parts and especially with the LS3 and LS7. A perfect example is my car in that I ran a 9.950 with stock LS7 injectors, stock air intake, stock intake manifold and stock halfshafts. Heck, I was even running with smaller LS2 headers which are probably equivalent to a stock LS7 exhaust.

I subsequently upgraded my injectors to 60lbs (reflowed LS7 injectors from Jeremy Formato) but that was only to give myself a little bit more breathing room as my IDC (Injectory Duty Cycle) was peaking around 95% at the track.

In reference to the .04 seconds, the reason I mentioned doing the swap at the track is because most people try to report timeslip improvements from different days which really makes the data unreliable. Since DA differences can otherwise make the same car run 2-3 tenths quicker (or slower) from one day to the next, saying something like "my car ran so much quicker with this mod" doesn't mean anything if the data was not all collected at the same time.

As for the surging, if you've got an LS2 then you probably won't have an issue as the LS3/LS7 MAF is considerably more sensitive to airflow turbulence, so much so that I believe Halltech had to create a diffuser to counteract the problem.

 

SO, YOU THINK AIR INTAKES ARE NOT WORTH THE $$$.......

I BOUGHT IT FOR THE EXTRA AIR INTAKE....

 

Vortex is a true cold air breather, along with Vararam, LPE, and Callaway, to name a few. Most of the rest just breathe warm/ hot engine air. You have to cut the radiator shroud on the cold air units, but it's worth it.

 

I swear by it....have it 5 years... stock vette 1/4 mile 12.4 a4 2005 conv.

 

I had one, took it off and sold it because it gave erratic performance which showed up while doing a dyno tune. Replaced it (and my cut shroud) with a K&N (and a new shroud). Problem with tuning disappeared and final result was much better. I don't know why it acted the way it did, I can only guess that it must have produced an unstable turbulent flow somewhere in the intake which the MAF didn't like. Some rpm ranges were actually producing less torque than stock. This was on an LS2.

 

Well I have one for sale, I removed it from my 07 C6 Ls2 with shroud for 250.00. it's like new, clear and all parts.
I replaced my engine and went with a 100mm Maf so I got a different one.

 

GREAT unit! GREAT quality! Iv'e been using it for 40,000 miles without any problems. Works as well as any quality CAI and it has a custom high Quality look. Large air intake for a cool forced air at speed. The LS2 and the LS3/ZO6 systems are different...so be sure you know what your purchasing.

 

I have one with the Vortex power duct and ran 11.7 @ 118 with intake, ported tb, tune in my '02 Z06. It's a great intake

 

thanks for all the excellent responses. Seems like a great deal!
Im going to go for it! But I will wait to bid until the end of the auction and do a last minute bid.. hopefully get it for a decent price.
