Sorry to hear that you had to remove the BMAD Bob.
I have heard of surging issues with the Blackwing and a cut shroud before. But the cases I am referring to involved using a cover over the Blackwing in addition to the cut radiator shroud.
Are you sure that it was the Big Mouth which was causing the surging or was it the cut shroud??????
Since the Big Mouth Air Dam is no longer on your car, and there is nothing directing air towards the hole in your radiator shroud, what is the advantage of having a hole in the radiator shroud vs opening up the foglight shrouds?

Get real bob, and no bob, I like you... feel better now? You p.m.'d me trying to let me know how smart you think you are. Fact is, you could not back up anything in a p.m., nor can you back up anything in public. You choose to ignore people that call you out...... and constantly ask you to back up your
, and YOU NEVER DO. Why is that bob? Let me guess, it's because you have an ego the size a Nebraska and are offended when people question the almighty "korreck". All anyone has ever asked for is for you to back up your mouth... 
yep, still waiting You have been proven wrong so often on this board, it's comical. But hey, keep swinging the bat, you'll have a fine following of newbs swallowing your
advice. So bob, why is it you feel the need to push bogus information??? Is it your vast knowledge in fluid dynamics???? Oh.......still waiting for that explanation.

To me the question of whether or not it does in fact out perform the competition has been sufficiently proven. I will list these in the order of most importance in a drag strip situation, 1/4 or 1/8 mile run.
1. It needs no forward movement of the vehicle to receive ambient or cold air. The vehicle starts the race receiving ambient air.
2. Vararam filter is very high flow design.
3. The sealed design and location of the intakes on the front of the vehicle in the airstream creates high pressure on the outside of the air filter. I believe this creates a situation in which there is less parasitic HP loss in the engine. Is this ram air effect, well not really but it has become the popular term for this sort of set up.

with you wholeheartedly Gary. It just cannot be put any better than you just put it 
I actually made a series of runs with the Vararam. I did NOT do only one day of testing or one run as was stated/implied.
I improved my previous best from 12.53 to 12.33 in going from the Blackwing to the Vararam. The difference taking into account weather conditions in my car in going from the Blackwing to the Vararam amounted to about 0.15secs improvement in ET and 3mph improvement in trap speed. Using the same tune for each intake.
I have since made a few tuning changes and as such cannot make a further comparison between the Vararam and the Blackwing since any further improvement I see now, over and above that 0.15sec/3mph improvement could be attributed to tuning.

I removed the big mouth for another test. About a week ago a tuner installed one and said he saw no difference at the PCM. As you know I don't have any diagnostic tools so I'm going to run at the strip without it. I want to see if it makes any difference. Until that guy tested it I was sure it did. Now I wonder. One way to find out.

Yes, there is only one way to find out.
But even if there is a miniscule difference, the drivability issues you describe (surging) would have to be taken into account.
And again, I tend to believe that the surging is the result of that hole in in your radiator shroud.
If the search function were up you would be able to find lots of information and many examples of this surging problem using the Blackwing and a cut radiator shroud.
The only surprising thing is that you did not have this problem before now.

Just to give you an idea, I had a choice between going to the Vette Doctors, about 380 miles away or ECS about 400 or so miles away to have my car tuned, or buying HP Tuners and giving it a shot myself. I have HP Tuners.

OK. I'll quit. The PCM was constantly adjusting the fuel trim because the Blackwing was drawing ambient air and also engine compartment air. I didn't notice this because we only raced the car. The other day we took it for a drive and the surging was quite apparent. I enclosed the Blackwing and the surging is gone.
To answer your next post that is the track I was talking about.

You say it is 350 miles one way for me, but it is closer to 400. I am well outside of the Steel City.
Just because you are willing to drive 800 miles no sweat, does not mean that everyone else is. Thats a long way.
But you will be doing so from a motor home and towing your car. I can only guess that makes a difference. I would be driving my Vette and carrying my drag radials in it (if that is possible).
Really nothing in it for me Bob. I drive 800 miles and whip your butt what do I get????
And if I bust something in the process, I am not towing. I have no trailer. I'm 400 miles away from home. It could take me a few days to get back. That would be a real problem.
Now OTOH.... if you wish to come here. I mean, after all, it was you who issued the challenge. You know where I am.

400 miles is closer to 7 hours. At a steady 60 MPH it comes out to around 7. I say 60 to take into account road construction, stopping for gas, food, slowing for speed traps etc. You are talking about better than a 6 hr, and heading for a 7hr ride from here to Richmond, Bob. And thats just one way. Hard to justify.
