Korreck Goes With Cold Air System !!!!!

Yes the man who said that there was no such thing as cold air, has now cut a hole into the radiator shroud of his 50th Anniversary Corvette, and installed a Big Mouth Air Dam which directs outside airflow directly to his oversized Blackwing air filter.
Korreck took the time to measure and cut this hole directly beneath his Blackwing air filter. He is somewhat vague as to why he chose this location
This would appear to be an attempt to forego the "unattractive option" of having his car breathe hot, underhood air as opposed to fresh, outside air..
The BOTTOM BREATHING system is said to offer more consistency in 1/4 mile elapsed times by the man himself. This after his preliminary testing results at Moroso Motorsports Park during this year's Corvette Challenge.
Dyno results are pending.......
The air dam directs outside ambient air, which is cooler than underhood air straight to his Blackwing air filter. The vendors of the air dam claim:
I could not agree more

In Bob's case its not just cold Air , it's an increase in CFM that is directed into the radiator compartment by The Big Mouth Performance Air Dam. Then By opening the radiator shrowed you are allowing the Blackwing a 360 degree suction , but because it creates a low pressure it sucks up all the colder ambient Air that is directed by The BMAD. Intern Bob is getting more consistent runs. We all know that denser air carry's more molecules that convert into higher HP.

You know, the next logical step for him would be to enclose the Blackwing with a plastic cover of some sort 
Guy has a Vortex Rammer without the lid.
Seriously however, I am glad to see him get the improvement that he was looking for. It is always a good thing when a modification works as intended and this seems to have worked for him form what he says he has observed. I say, Bravo.
Even if he does have to sit down to a plate of crow and gravy. It will still wash down with a few of these

I'll be laughing about this for a week, at least. And to think I told you awhile back to lighten up and have some fun. Good job. 
I saw an ad for the Big Mouth and that's what got me to thinking about this mod. At 170/180 I would run in the 12.7 range. At 195 I would run 13's. I talked to a lot of people and they were as confused as I was as to what was going on.
Last week at Moroso I ran 12.92./12.94 all nght regardless of engine temp. To run faster I have to 'power brake'. I never do that in competition. I always leave from an idle for consistancy.
If I have a chance this weekend (racing in 3 events) I will try and see if the car is any faster. Fri night and Sat night are 1/8 events, so hopefully Sat morning it will be cool enough to give it a go. I would hope to see a 12.62 or 12.63.
OK, you guys have a good time with this. Just remember three things. The Vararam is bogus, no such thing as cold air (I don't have a freezer in the car) and no such thing as ram air (I don't run 700 MPH).

It would be really interesting to know a few things regarding your runs. Among them what the DA was when you ran those times, as well as the 60ft times when you ran the 12.7s, vs the 12.9s.
You ran 12.7s without the new system and 12.9s, sometimes at the same engine temps, with it? Did you power brake to make it to 12.7?
There must be an explanation.
Also, what were your trap speeds in the two sets of runs?

I don't track DA. I use an HP correction which gives me good dial ins. I'll start checking DA just for you.
60' times are terrible but consistant. About 1.95. On 12.7 runs 60' were 1.90. That's my next problem to work on. May have a solution that I'll be trying this weekend. As I said before, I have to power brake to get 12.7's.
Here is data before I made the changes.

Notice the spread? That was killing me.

[QUOTE=Korreck]To many questions. I don't want to make a job out of this.
Ok, just one issue here for me and then I'll leave ya the hell alone myself.
"Now let me correct your errors. I am not getting 'cold air'. I'm getting what appears to be more ambient air vs hotter air from my engine compartment."
Is ambient warmer than hot air........or coooooler?
Can you re-read your quote with a straight face and not see how silly this Johnny Cochrane monologue is?
"If the intake fits, you must admit"!

[QUOTE=simpleman68]
Just to keep peace I'll agree with you. I just get so sick of bogus claims by many of these aftermarket companies.
Maybe I do go overboard a bit, but there is nothing cold about 85 degree temps. Cooler yes, cold no.
And I was just jabbing EB about making this work. I can always use his help and do not mind sharing data.

Hey, I'm just grateful that it appears Korreck has not lived up to the axiom "you can’t teach an old dog new tricks".. Seems like he is trainable after all!!
And I too hope he sees whatever improvements he was looking for.. That's the whole point of mods, right?

I have the mind of an 18 yr old. Well, maybe not that bad! Let's just try and have fun and share info. My wife is the only person in this family not trainable.
Peace.
Edit:
I'm getting worried about EB. He hasn't posted in at least 15 min.

Why stop with that little opening for the air... I suggest you that you put a 3' x 4' funnel on the front of vette. Have you tried running your air conditioning venting to your air intake box so you can get colder air in the engine ???
