Brian P Posted July 28, 2004 Report Share Posted July 28, 2004 Am I missing something? I thought I had an engine that would benefit from the cone filter (power above 3500rpm's) I go try one out today. That type that has a shield around it to sort of prevent hot air from getting in? And a mandrel bent aluminum tube I guess 3". What the hell? I got NO power from it, only this annoying drowning noise and the only slight difference was at the very top of the powerband, at the expense of EVERYTHING that engine had from 1500-3500rpm. I mean TONS of noise and the engine is just hanging out there. Maybe I should try a bigger one? As soon as I pulled into the driveway I ripped it out (didnt even loosen the clamps) put the box right back in and got my power back. I've got to be missing something here.....

RareGMFan Posted July 28, 2004 Report Share Posted July 28, 2004 Isn't that kind with the heat shield around it just as restrictive as stock, if not more? I mean, I know it's keeping some of the hot air out, but aren't there just a few tiny holes letting the air in? Quote Link to comment Share on other sites More sharing options...
Nick1234 Posted July 28, 2004 Report Share Posted July 28, 2004 Okay, the one he is talking about i believe is where there is a chrome plated sheild covering only half the cone filter. The other 180 degrees is full exposed. Second, you could try to give the computer a few days to adjust to the change. Not just after a short drive. Third, it might get better, but now that there is so much more air coming in, the computer isn't going to compensate for more fuel. Thats how i came to understand it. pending on where you placed the filter, you are prolly just sucking in more hot air, even with the shield, and that does no good at all.

Brian P Posted July 28, 2004 Author Report Share Posted July 28, 2004 well it's not like I was sitting at idle for an hour. The underhood definetly wasn't hot enough for that to be the reason. It didnt have that chrome shield, it sounds like what hyeboy described it. There were 3 holes plus the very front was open. What a POS Quote Link to comment Share on other sites More sharing options...
cutlsp Posted July 28, 2004 Report Share Posted July 28, 2004 Brian you of all people should know that the stock air box is better then anything you can buy. now if you make a cai for your car and the same thing happens :? i don't know what to do then man Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted July 28, 2004 Report Share Posted July 28, 2004 Go gut your airbox. Give it a few days. It'll work better than any cone you can buy. Quote Link to comment Share on other sites More sharing options...
Gearhead43 Posted July 28, 2004 Report Share Posted July 28, 2004 Not more FUEL .. MORE AIR.. the ECM has to adjust. Also Before you are getting more air than the ECM is designed to "know" about , it's going to LEAN out the mixture a bit.. cuasing a slight loss in low end toruqe. But you will notice a gain at the high end. Quote Link to comment Share on other sites More sharing options...

SigEpCutlass Posted July 28, 2004 Report Share Posted July 28, 2004 see the dyno here: you're gonna loose torque...PERIOD. That's why I haven't bought one. There's not enough gain to bog my engine for every day driving. bigbuls sent this to me a while back. Quote Link to comment Share on other sites More sharing options...
test4echo Posted July 28, 2004 Report Share Posted July 28, 2004 Well, I have to disagree with all of you on this one. I have no dyno testing or readouts to show. But I can say unequivically this cone filter has made a HUGE difference in my 92 Z34. A hard acceleration from a stop (WOT) has greatly increased not to mention the growl I love to hear. The seat of the pants factor has greatly increased. How do I know? Cause I ran my semi-CAI for a few weeks. Had freinds over to take her for a spin. They ALL noticed a huge difference. Then I failed my e-test and decided to put the stock box back on. It really hit me then how much difference this Cone was making. I can't deny it. I put my Cone back on again cause I couldn't take it no more. And yes, I did have a new filter in the old stock box. Now I won't deny that having that Heat shield on there may restrict my Cone more than a wide open K&N, but Its definetly much better than stock. No doubt about it. test, Quote Link to comment Share on other sites More sharing options...

THe_DeTAiL3R Posted July 28, 2004 Report Share Posted July 28, 2004 I started a thread earlier this year (probaby around April).. cone filter vs. stock (gutted) airbox at the dragstrip. I lost a couple tens of a second with the cone filter sucking in hot air.. Me and my friend build a REAL CAI on his Sunbird 3.1 (the cone filter hangs below the engine that it would not suck ANY hot air..) we took it to the track and got a 16.8, which is kinda average for that car (don't know what it would have got with it's very restrictive looking stock airbox). I can see how OHC engines benefit from more air, cause they got more power in the top end, but pushrods are all about torque. Quote Link to comment Share on other sites More sharing options...

Shit, sorry Brian, I didn't know you were talking about a pushrod. I have No experience with that engine's architecture. So I guess I'll just shut up now......hehe test, Quote Link to comment Share on other sites More sharing options...
SigEpCutlass Posted July 29, 2004 Report Share Posted July 29, 2004 yup everyone is saying the same thing...just look at the dyno. lol we have a pushrod, and it's all about torque. losing torque is BAD! lol Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted July 29, 2004 Report Share Posted July 29, 2004 see the dyno here: you're gonna loose torque...PERIOD. That's why I haven't bought one. There's not enough gain to bog my engine for every day driving. bigbuls sent this to me a while back. You missquoted that chart............. It DOES gain torque, ALL across the powerband. 5+ lb/ft from just off the shift, all the way to the rev limiter. Remember what I told you about the numbers being incorrect due to the shift spike at the beginning of the run (the chart was cropped off a run that went from the 1-2 shift up to the rev limiter in 2nd). You HAVE to look at the actual plotted power curve, NOT just the numbers at the top of the chart. Quote Link to comment Share on other sites More sharing options...
SigEpCutlass Posted July 29, 2004 Report Share Posted July 29, 2004 wow i need to start reading a bit slower. I switched it around. However, what concerns me is torque below 3,000 RPMS. Correct me if I'm wrong, but doesn't it have a negative effect in that range? I've had a few people tell me different things, so I'd like your take.

Manny Posted July 29, 2004 Report Share Posted July 29, 2004 ...Someone mentioned some time ago that if you had a cone filter without upgrading your stock chip to an FFP chip, you would lose some low-end performance... Quote Link to comment Share on other sites More sharing options...
SigEpCutlass Posted July 29, 2004 Report Share Posted July 29, 2004 correct me if i'm wrong again...but there's no ffp chip for 3100 engines due to the computer change right? Quote Link to comment Share on other sites More sharing options...

SigEpCutlass Posted July 29, 2004 Report Share Posted July 29, 2004 so as I said originally I am correct. Brian has a 3100 as do I, and therefore will loose torque because he can't get a FFP chip. See everything comes together eventually. Quote Link to comment Share on other sites More sharing options...
Manny Posted July 30, 2004 Report Share Posted July 30, 2004 oops! :oops: sorry fellas.... I should read slower too. didn't know u had a 3100. Quote Link to comment Share on other sites More sharing options...
