ok guys, i was messing around in my garage one day and i designed a ram-air intake that comes through the corner light. for the one i made you need to have your battery relocated as i do. i used a ricotta cheese container and a tube you would mail a poster in. so i put this in and took it to the track. now for some reason all this time the best i could get is a 15.8. remember all i have is a cone filter. so i run my car one time and what do i get? 15.3!!!!!!!!!!!!! my car is actually running decent now. im so proud. i also noticed with the ramair that i get improved highway mileage and my engine temperature is significantly reduced. normally my motor runs at halfway in between hot and cold on the guage, last nite i was driving to and from the track my temperature was at about 1/4 the way up. ok yes, outside temperature last nite was about 46 degrees, and my other runs at the track were around 80 degrees. i do live in central florida. but i figure the effects of the ram air were just intensified by the temperature. therefore the ram air does work. what do you guys think. i have pics of the timeslips on my homepage and i will have pics of the ram air up shortly.

Still no pics of the intake set up

 

Improved ET is nice, but for all we know it could have just been much better conditions that night, or maybe your launch improved significantly. What were the conditions, 60', trap speed, etc for your 15.8's vs the conditions, 60', trap speed, etc for your 15.3?

As far as your temp gauge only being 1/4 way up, it sounds like you might have a stuck thermostat because it should always be right in the middle. If it's stuck, it may not have been allowing enough coolant flow in hot weather and you could have been mildly over-temp but just not enough for the guage to start to show it. In the cool weather last night maybe now it's allowing too much coolant flow and didn't let the engien get fully up to temp. That could have helped you run faster times also.

So I don't believe that your ram air is giving you a FULL half second and that there are probably a bunch of other things going on as well.

 

I mean dang, just kill his high why don't you. I agree with you tho.

 

yea i thought about it, but when i sit at a stop or something long enough the temperature goes back to halfway. and also when i take the ram-air it runs at halfway like normal, so the thermostat being stuck cant be it. yes i agree on the ram-air not being the only thing giving me a full half second. my driving did improve, but only a small amount. but like i said before, the temperature outside was 46 degrees compared to being around 86 every other time i went to the track. to see my time slips go to my homepage.

 

oh, and the reaction time doesnt not count against you on your 1/4 mile time at my track. i can prove this if need be, simply look at some of my timeslips. it says the winner of the race at the bottom and that isnt always the person with the fastest time. the car i ran against when ran the 15.3 was a gsx eclipse that ran a 14.9 but i beat him head to head.

 

The colder weather and better 60' helped out your improved 1/4 mile the most. If the temp/humidity were identical and 60' were roughly the same then it would be due to the ram air. Either way, it probably is still good for at least a tiny gain.

That alone was probably responsible for "most" of your half second. Your custom ram air setup may have helped a "little" but the bulk of it is right here. So for the purposes of your ram air claims, you're really comparing apples to oranges. The best thing you could do is at the same night at the same track, run both setups back to back and see what the differences are (if any) and also keep close track of your 60' times. Trap speed in MPH is what you would want to watch most closely though.

Yes, I know R/T doesn't matter - I moderate the dyno and timeslip forums.


I think the title of this thread should be changed to "cold temps make a huge difference"

 

IMO the only way to tell if ram air is really working is to compare g-tech 0-100 times the same nite with and w/o ram air port open... As I said, just my opinion...

 

yeah here is the ram air that I made for my car.

 

that looks hot plurco

 

Plurco,

That looks awsome! I admit that I had to laught at first. Ram air intake that work made out of Ricotta Cheese container. LOL! Now Home Depot will have to stock Ricotta cheese for all of the .org builders of CAI and ram air. heh.

Another note. I think that humidity can effect you quarter mile time as well. High humidity suppresses detonation, how that would effect are cars, I don't know. Just throwing out another random variable.

I know that ram air works at very high speeds. It works better and better by degrees of powers not multiples, but to get there you have to be doing 100+mph. Which you shold be around at the end of your quater mile run.

P

 

anyways, even if its not working as much so in the quarter mile. it does lower intake temperature on the highway making my car run smoother. therefore the title should stay.

 

Nice job- One thing you might want to consider- Ive seen some filters that are the "doughnut" style- you might be able to get marginally better performance out of it as the air can get pushed through more surface?? - also more "straight through"

For example of the style-

Only possible knock: what about your headlight? Are you legal?

Oh- and good news! Ive heard that ram-air starts to work at 70 MPH

 

Sweet! I am going to make a custom ram air this week.....mid 13's here I come. So this is a proven 1/2 sec mod???

 

Hahaha- good one...

 

Do you have before/after IAT readings from OBD-II, or measurements from an external thermocouple to confirm that?

 

I have a ram-air set-up using the PR piping from the foglight hole up to a JWT pop and a Techtom so I'll try to get some readings with the tube open and plugged.

One major downside to this is the filter gets dirty very fast.

 

i have a pda hooked up to my ecu in 2 weeks....im gonna check the intake temps through the obd2 scanner and try this to see if it really does work....however...a temp drop will do nearly as much for us as a forced induction max....so even if the intake charge is a clear 10-20 less F, the gain would be marginal i believe...

 

lets see thermostat being lower than normal is enough confirmation for me, especially when i put the corner light back in and itll go back to the normal operating temp. anyways, i'm 17 havent been able to get a better time than 15.8 and finally get a 15.3 im ecstatic. thanks for input but im a believer. 1/2 second reduction? no, but it definitely contributed.
