Another ram air test. Proof it works. I ran the car with the ssra on the car first few times at the track. A few weeks later I decided to take it off to make room for a trans cooler. Went to the track and wasnt happy with the time I ran. So...I decided to put the ssra back on.
This wasnt meant to be a test to see if the ram air actualy works...I was only trying to make room for the cooler but I ended up with some concrete results that proves ram air works.
(With ssra)
DA -249
1/4 12.740 @ 109.22

(took ssra off)
DA -778
1/4 12.9 @ 107
I didnt save my slips for these because I wasnt happy with them but I can tell you ALL the numbers were not as good. I think best 60'was like 2.1xx.
(put ssra back on)
DA -1245
1/4 12.638 @110.04
https://ls1tech.com/forums/drag-raci...ed-12-6-a.html
Now to me this is concrete proof that it works. EVERYTHING else on the car was the same BUT the ssra. DA was different but as you can see the car did better with the ssra in worse DA! Thats proof right there

Also what I didnt mention is that the 12.9 without ssra was the best of the night. Without the ssra actualy put me back at 13.0s for a couple passes.

IAT stay pretty much consistant with outside air temps (a little higher).When your on the highway and you give it some gas the IAT drops a couple degrees. Never watched it while at WOT though. Probly drops a few more.
When I took the CAI off the car IAT were very high after the car had been sitting (heat soak). It still dose heat soak with CAI but not like without CAI or not like if you had a metal CAI kit.
Edited...
I watched it a little closer yesterday when I started the car up. It still does heat soak a good amount with the CAI. IT was at 105f when I started the car. But temps start dropping even while idling after startup. Then as soon as you start driving temps drop fast. Temps drop really slow without the CAI.

This is a pretty interesting result, by the way, thanks for sharing it. .2 seems like a big difference. I like that about these engines, things that would not really be definitively measurable on smaller (or lesser) engines, become more obvious, which is awesome.

Heres some info that might sooth the obsession a little....

Its hard to see spending money on this little piece of metal but the results back it...Its more cost effective then a gear install as well.

I am just interested in the science behind all kinds of things having to do with cars. Please don't think I'm questioning the product or the results. I'm just curious about why it works. The science behind the controversy surrounding this is certainly above my head, so I don't want you to get the idea that I even have an opinion as to whether a ram effect can increase manifold pressure (actually, my opinion, if anything, would be that it can - I only would dispute a claim that this constitutes proof that the gains are due mostly to an increase in manifold pressure).
I don't have a car that can use any of these products, but I'd like to fabricate something for it, and I'd like to understand the best way to do that. I'm also all for incremental gains, so if I can get even .1% more VE, on top of gains from cooler air, or resonance effects, I'd definitely take advantage of it.

1st and 3rd 60's are listed in the threads attached. I dont have an exact 60' to tell you for the 2nd (the one without ssra) because I was so disapointed I through the slips out. I remember looking at them though and ALL the numbers sucked and I considered it a wasted trip. But I can tell you I was only doing 12.9s,a couple 13.0s,and like I said best 60' was in the 2.1xx area. Mph was down to 106-107 and 1/8 was down to 86mph.
When I took the ram air off I knew I might be disapointed when I went to the track but I didnt think it would have this big of a difference. So I couldnt live without it and I put it back on my car.

Gotcha, didn't catch the links. Although the 1.9 60's compared to your 2.1 60's could be your .2-.3 difference. The SSRA is going to have little to no affect on your 60' times. Not trying to take away from your results just stating my opinon on the possible difference in et. Looks like you definatly gained some MPH with the SSRA though.
I ran yesterday with the chris1313 ram air and gained a mph over my previous best, but unfortuanly don't know how much I lowered my et with the ram air. The only times I have to compare was my previous best of 12.6 @ 110 w/ 1.9 60' with only free ram air compared to the 12.03 @ 111 w/ a 1.61 60' I ran yesterday with the ram air installed and air box sealed.

The ram air deff did something for throttle response. My car isnt making a **** ton of power so I dont have a problem with being consistant on these hoosier drs. I did enough passes to believe that the ram air does help off the line. If its the availability for colder air right away or whatever I dont know. All I know is the proof has been proven
