GazzaGSi Posted August 7, 2006 Share Posted August 7, 2006 Sunday at the pod I would say for every 3 cars that went up the strip, 1 had a headlight removed - obviously the air filter side. I was just wondering if it does really help? Would people recommend it for someone who was about to go on? I know without the headlight it is alot easier for ai to get to the filter but would you run a slower time if you left it on or is it not that significant? Just curious...

Daston Posted August 7, 2006 Share Posted August 7, 2006 surly the benifit you would have would be evened up by the drag it would cause Quote Link to comment Share on other sites More sharing options...
terribleturner Posted August 7, 2006 Share Posted August 7, 2006 I always remember Rayman telling me about taking his out on a very very early morning and going for a blast. He reconed that the extra air in there made the car feel move positive. I'll be trying it even if for a couple of runs. Quote Link to comment Share on other sites More sharing options...
squiffy Posted August 7, 2006 Share Posted August 7, 2006 i put a piece of ducting in over the weekend and it has definately made the exhaust louder! Quote Link to comment Share on other sites More sharing options...

TLicense Posted August 7, 2006 Share Posted August 7, 2006 Ahh the old arse dyno placebo effect! I would have thought you would gain no more than 5, maybe 10, 15 at a puch BHP from doing it. I know race drivers in F1 who didn't notive that they were 50bhp down.... More responsive? Maybe I don't know. I wonder if I put my head under the bonnet of someones car for an hour or two and said I'd modified X, and it'll make the car run better, but had really done feck all, how many people would think they could "feel" the improvement? (That's ignoring the fact that if I stuck my head under the bonnet of any car for a couple of hours, chances are it wouldn't run again!)

Guest gzaerojon Posted August 7, 2006 Share Posted August 7, 2006 surely if you can get a extra flow of air forced directly into the air filter it's got to be a good thing right? hopefully not a shameless plug, but my fibreglass fabricator and i are currently working on something interesting at the moment Quote Link to comment Share on other sites More sharing options...
TLicense Posted August 7, 2006 Share Posted August 7, 2006 Dminishing returns though maybe? Quote Link to comment Share on other sites More sharing options...

Case in point; those maplins resistors people sell on eBay that richen up the mixture. A couple of NA folks on here have sworn they make the car more powerful Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted August 8, 2006 Share Posted August 8, 2006 aint it supposed to be good for a couple of tenths off your time,i normally run with no light in,but my best time was done with headlight in and never reset ecu.just practice and you will improve as you get used to it all.trying different things.

JohnA Posted August 8, 2006 Share Posted August 8, 2006 I've experimented extensively with this 'ramair' supercharging effect. You can get 5-7% bhp increase at high speeds if done properly. The stock supra setup is NOT such a design though, so if left unmodified it is impossible to pressurise the airbox. You can however reduce the vacuum when the throttle is opened widely at high revs - plus the cool air effect, which is even more important for power. I think that what this guy felt was mainly placebo, the drag from the extra air piling under the bonnet would offset any gains. For real difference he needed to have sealed the front intake, have it protrude by a couple of inches, with a belmouth --- and block off the side airbox intake.
