vortex generator

[audiman]

bought a vortex generator off fleabay and fitted it last night into airintake pipe


has made the frontera more responsive better accleration dont think topend has improved but seems to of ironed out flat spot at low revs and quicker off mark


was wondering if anyone else had used them and if they felt it had improved the performance of their motor


cheers

I'm presuming this is a wind up?

..and you're talking about one of these ebay modified baked bean cans:




Please tell me you didn't buy one of these

[audiman]

yep

take they are a bad idea then


good side is i only paid 99pence

cheers

Lee

[domino]

99p + postage I would presume?

They do nothing at all - it's like the ebay resistor mod. Lesson learnt though huh

[audiman]

well when the vents were set to 90 degree the airflow was so restricted that i could only start it by squeezing the throttle pedal so opened the vents back up to 45 degrees ish and now starts on its own

was worth a try and like you said lesson learnt

think a will save up for a k&n induction kit


cheers

suppose other option is

take off the 8v head stick a 16 v on it remove the injection system and stick a set of twin 40's on

but again its all comes down to money and I can't seem to find anyone that does software for remapping the ecu on a 8v engine suppose the starchip route would work but dont fancy screwing up the ecu by my bad soldering


cheers

There are mobile guys that'll remap an 8v happily but finding one who isn't a cowboy would be nigh on impossible.

The webbers are a good idea but you gotta remember, it's a big ole Frontera, not a wee Astra GTE

[audiman]

yes I know it will never be an astra gte

was thinking for low down power would be good when offroading and need a little bit more umph ie getting stuck


plus webbers do sound good


i remember my youth when i had a sunbeam ti with twin 40's at low revs they sounded amazing and put a big grin on your face

perhaps I am just trying to recapture that....................


cheers

I was interested in a Hiclone or two as my 2.8 Tdi would need two they reckon.
Then the dmf went.
Any one tried them? They look more thought out and better made than these things. Though I think first a K&n filter and less bends in the air intake would help as would a better flowing exhaust.
But first the dmf as there's not much point if the engine & g/box dont connect.
Whan I was young i converted my Morris 1000 van to a Riley head with twin carbs but before I fitted it I got a mate to smooth out the differences where the inlet and outlets met the manifolds so that they lined up to the size of the holes in the gasket. There was a lot of difference and I kept breaking wheel studs taking on Midgets & Sprites off the lights.

Hiclone is just more snake oil, anything in the way of you filter and intake is just that..in the way, causing an unnecessary obstruction to the air.
Only two things should be there, a turbo or supercharger.
None of these cheap wonder products work or have been proven to work, if they are so good and cheap wouldnt you think the manufactures would use them

Well it used to be called "gas flowing" but I didn't want to get too technicackle.

My first vehicle was a morris van which I had for nearky five years .I got into bikes and sold it before I went to Germany.
Can i have a "stay on topic "monster waving a sign please?

[jason]

[Frenchfarmer]

[audiman]

well seems like i started a hot topic on this one

porting and gasflowing had never even entered my head

but as per my second post it all comes down to how much spare cash you have got to really improve the performance of your motor

which i dont have so think i will settle for a K&N induction kit in the near future unless i stumble across a bargain

many thanks for all the info greatly appriceated and helpful

cheers

Now now children, play nice

[Drift]

Just to wet your appetite, my old sport, the filter kept the air intake higher and less prone to sucking in water when offroad but didnt do much else, sounded great though
