Dremd, thanks for your kind offer of help. I understand most of what I read concerning automobiles. I was an apprentence & journeyman automobile mechanic in the mid 1950's but soon decided to move to a major airline but have never lost my interest in cars. I still turn wrenches on 3 vehicles and belong to several internet automobile groups. I am currently investigating a hybird, front wheel drive with an electirc motor on the differencial - the simpler the better.

An official welcome to the site! I'm glad you returned.

I have often been intrigued by the notion of a passive turbo. I keep thinking of a post somewhere long past, where the vehicle owner devised a zero-psi turbo to reduce pumping losses or somesuch.

So what kind of aircraft do you wrench? There are a few pilots on the forums -- also I'm a frequent flyer and aircraft enthusiast. Now, If it's a CRJ-200, I don't wanna know

Best FE to ya

i dont get the idea of a passive turbo. Its very easy to keep a turbo car out of boost, just dont lay into the throttle. Well i guess it really depends on what size turbo also.

Turbos when used correctly can increase FE.

For example, i designed a custom kit for my little brother that utilized a evo8 twinscroll turbo on a bone stock GSR b18. It made 275 hp and 240 tq with full boost @ 3000 rpm with a restrictive 2.5 inch exhaust and cat. On the highway he could get 40 mpg staying out of boost mostly without any special driving techniques.

Well, now I definitely believe you :-)

I would love a similar setup myself.

Civic Hx is a nifty car; sometimes I wish I had one, other times I'm glad I have the VeeDub.

Be sure to check out AndrewJ's Aeromodding Civic thread. Definitely a worthwhile read for any Civic Owner.

Dear Gentlemen,

Forget this system. I have had this system fitted to my vehicle since August 2008.

To date it has recorded no improvement in fuel economy, (I have 7 months of test data prior to the installation of this system and 3 months post data for you to compare.)

To this date it has recorded no improvement in emissions, (at my last vehicle test the emissions were higher than previous tests and I have the official UK test station data to back this up.)

Please be aware that when Mr Heeley road tests your vehicle he will switch off everything that might increase power requirements. He will also use his own test route and report a favourable test figure. If like me you have climate control switched on during normal useage, a standard load and a fixed daily route your fuel/emissions data may not change favourably.

As one earlier correspondent suggested, George Heeley is extremely busy. (and will take time to respond.) I have complained to him since August 2008 about the failure of his system and his total lack of interest in resolving the issues, (if you wish I can forward ALL CORRESPONDENCE BETWEEN US (I am meticulous at keeping records.)) At the time of writing I have given a deadline for the removal of the system and a full refund. The response was that the system would be removed during week commencing 24th November 2008, One full week after the deadline I had given. His chosen deadline has been and gone and I still have the offending item installed in my vehicle. As a result of previous correspondence with Mr Heeley I sincerely doubt that there will be a solution without resorting to legal proceedings.

All of the above can be proven. I have recordings of telephone conversations and emails received and sent. Based on my experience, (and I do emphasise this is my experience only.) This system has failed to achieve any of it's stated performance figures.

I cannot advise if this system is good or bad. I can only relate my personal experience.

Yeah reading through their site its a high-flow intake. . .High-flow unless carefully maintained as is said above causes engine damage and does not improve anything.

I've got one and pretty much every week to keep the thing clean I wash it and coat it with a thin film of oil(not the stuff the filter company sells, I found a substitue company and bought bulk)

[dichotomous]

you can definately have higher flow AND higher filtering properties, lost more cleaner air. but you need a bigger filter for that to happen.

Heh, I guess I forgot to mention it is also much larger. It's been a while since any of my vehicles had a standard air intake, so I guess I overlook that.

Welcome to the site, Easy.

Cars are just like airplanes in one respect: If something worked and were cheap and easy, everybody would be doing it by now.

There must be a million guys out there trying to sell some type of snake oil to the credulous. In the diesel pickup community it is two-stroke oil and acetone. There are still people insisting that HHO generators work.

MPG is just like racing. If you want big performance you gotta take radical steps. Check out basjoos and Phil Knox’ (Aerohead) vehicles. Radical, but they get big results. Most of us here drive in a way that drives the “texting-while-driving” crowd absolutely nuts, but we get results.

If somebody offers you something that claims huge results for a couple hundred dollars, you “BS-meter” should be pegged.

. . .I text and drive. . .I also manage to do pulse and glide. Although, I only drive 1 mile per day. For the record PaG'ing is not terribly effective when your commute is exactly up hill for .25 miles downhill .1 mile, stop for red light, .1 mile slightly down hill, turn speed limit 15 mph, coast to a stop. and then do it in reverse. I coast all the way (.25 miles) down the hill though in the afternoons, sometimes with my engine off because the speed limit increases so I don't have to break and I have a wide high speed turn and then I'm home.

Come to the conclusion its too much effort for such a short drive, because if I drive normally I fill up(10 gallons) maybe once every three weeks.

So make it every 4 weeks :P

Or ride a bike... LOL. Maybe even an E-bike.. very cheap preparation.
