Chris Bemis 5 Posted October 16, 2013 Share Posted October 16, 2013 Our speed limits are 70. And if you're doing 70, you better be in the slow lane. Link to post Share on other sites
malibuguy 14 Posted October 17, 2013 Share Posted October 17, 2013 Muscle cars used cowl induction as a side benifit of shit aero. The hood and windsheild profile of these cars and other modern ones are very sleek and there is a much less high pressure build up at the base of the windshield. I think your benifiting more from charge temp then pressure. Id like to put a scoop in the dummy foglight to feed the box to try out on ours Link to post Share on other sites
Greg_E 211 Posted October 17, 2013 Share Posted October 17, 2013 Need to tape a piece of string to the end of the funnel and put a camera on it to see if the string is blowing out towards the windshield or in towards the engine. That would tell you immediately which way the air is going. Link to post Share on other sites
Chris Bemis 5 Posted October 17, 2013 Share Posted October 17, 2013 (edited) I did consider doing the foglight to air box modification. I still may try that. Greg, I'm not going to risk one of my cameras out on the hood of the car. Revving it up in the driveway wouldn't be the same effect as driving down the road. It doesn't really matter to me at all if the mpg gain is because of pressure or temp. I'm just thrilled to increase the mpg for free, with stuff I already had laying around.

psquare75 35 Posted October 17, 2013 Share Posted October 17, 2013 Just curious.. Do you guys have e10 or 'real' gas? makes a difference when comparing MPG figures. Link to post Share on other sites
Greg_E 211 Posted October 17, 2013 Share Posted October 17, 2013 Mine is all e10 and about to be the less efficient winter blend of e10. Link to post Share on other sites
tommyspark 24 Posted October 17, 2013 Share Posted October 17, 2013 (edited) The majority of gas stations here are e10. There's a.few w.pure gas but its expensive.... Edited October 17, 2013 by tommyspark Link to post Share on other sites
Chris Bemis 5 Posted October 17, 2013 Share Posted October 17, 2013 I'm not sure what we have. I'll pay attention the next time I fill up. I think it's E10 though. Link to post Share on other sites

Dori 13 Posted October 18, 2013 Share Posted October 18, 2013 With all this rain talk, what happens if water gets in the induction tubes? All I have done is the basic removal of the resonator. What happens if a little water gets in through that tube and into the box? Link to post Share on other sites
Greg_E 211 Posted October 18, 2013 Share Posted October 18, 2013 Normally it looks like water runs down into the resonator and drains through the hole in the bottom, can't remember if there is another hole in the airbox to do the same thing. Link to post Share on other sites
tommyspark 24 Posted October 18, 2013 Share Posted October 18, 2013 I've driven MANY times in the rain and have never got water in the box. Believe it or not, there's not enough "suck" or vacuum if you will to suck water into the box. I had.a buddy rev it up slowly go 4k with each of my hands on the two snorkels, and was actually surprised by the weak "vacuum".... And even if water did enter.the box, I think the filter sits too high for the water to go through it. You'd need a lot more "intake vacuum/suck action" to.actually get water to go through the filter..... Link to post Share on other sites
Chris Bemis 5 Posted October 18, 2013 Share Posted October 18, 2013 Exactly, tommyspark. I think even if I ran a garden hose down the cowl induction, that water would just pool and drain in the bottom of the air box. No way it's getting sucked up through the filter and into the engine. You should see the radical ram air I built on another car and have never had a problem with water. Link to post Share on other sites
tommyspark 24 Posted October 18, 2013 Share Posted October 18, 2013 I had run a 3" duct connected.directly to the 3" opening.on the bottom.of the.stock airbox.on my last.car, and.never had any.issues..... and it sucked in.pretty hard Link to post Share on other sites
tommyspark 24 Posted October 18, 2013 Share Posted October 18, 2013 Cut a.round.hole in the grill for a true ram air.... it was good to go Link to post Share on other sites
tommyspark 24 Posted October 22, 2013 Share Posted October 22, 2013 (edited) After Chris determined that the Spark does not like hot/warm air, I got to thinking. As I drive around, according to Torque, my intake temps, while moving, are 4 degrees higher than the outside air. So I wanted to see if I could get them closer to the outside temp number. Also while sitting at a light or in city stop n go traffic, IAT numbers rise pretty quickly. Hopefully this will slow it up a little bit I used the stock "snorkel" and extended my snorkel about 4 inches further down into the fender well. And wrapped both snorkels with Holley heat reflecting tape..... haven't driven around yet, but I will post numbers when I see if it helped or not......

NOMAD 1 Posted October 23, 2013 Share Posted October 23, 2013 This is Chris. I decided I didn't want to have my facebook and name out there for the public google search any more. tommyspark, I'll bet that insulating the hoses sure can't hurt. Although, I will say that when I tried the warm air mod, the pipe barely even got warm to the touch and I think that black vinyl wrap on the factory snorkel is an insulator too. Also, regarding the above discussion, the gas pumps at my local Kroger, where I get gas doesn't say anything about E10. I think Kroger gas is just rebranded Shell. I'm in the Detroit area, so the gas will be switching to winter blend soon, if it hasn't already. Link to post Share on other sites
NOMAD 1 Posted October 23, 2013 Share Posted October 23, 2013 Here is the final version of my cold air / cowl induction set up. All it is, is the neck of a bottle of weed killer, an old radiator hose, a 45 degree PVC fitting and the stock snorkel piece. I popped off the restrictor plate on the stock snorkel neck and wrapped electrical tape around it until it fit snugly in the hole. I assembled the rest and cut the factory rubber molding so that the funnel could lay flat and also, so I could put it back to stock in under 1 minute. I did drill one hole in the cowl plastic, and install a locking style nylon push pin to keep the funnel in place. It's tough to say with the changing weather, and likely the changing fuel blend, but I think I'm getting an extra 1-2 mpg out of the modification. Link to post Share on other sites
tommyspark 24 Posted October 23, 2013 Share Posted October 23, 2013 Just got home from school. It's about an 18 mile drive, with only about 7 miles of it being highway. According to Torque, while cruising 40 MPH and higher, the IAT read 1-2 degrees higher than the outside air. It used to tell me 4 degrees higher regularly. In the city it never got over 7 degrees higher than the outside air. But while city driving, I noticed a day and night difference in how fast the IAT drops after you start going from light to light. It's almost immidiate. Before this "mod", it would take a minute or so for the numbers to drop. (outside temp on the way to school was 67; and 64 on the way home) When I get the time to, I'm probably going to wrap the intake tube and see if this helps even more. I'm curious to see what would happen if we removed the "ram air" snorkel, but with my fender snorkel down as far as it is now, I don't want to run the risk of sucking in water through that snorkel. With both of them and the intake pressure being split, there just isn't enough "sucking vacuum" to have to worry about it I can't comment on power gains from this modl. Despite the exhaust work and intake mods, I don't drive er like that. I like my 39.1 at the pump I do try to drive er WOT once a week for blow out reasons. I'll see if there is any kind of power gain then....... . Link to post Share on other sites
tommyspark 24 Posted October 23, 2013 Share Posted October 23, 2013 Keep us posted on the cowl mod. It's too soon to safely say I"m getting more MPGs now, but I reset the gauge before leaving. I'd say it's 60 %city and 40% highway to school. I pulled into the driveway with the gauge saying 40.1 MPG AVG. It was a warmer day today though so time will tell....
