Is this BS or true?
 

on ebay some is selling intake senor claim more HP gain and throttle bypass claiming 8 hp gain True or BS? http://cgi.ebay.com/ebaymotors/ws/eB...tem=1853720277

more BS
 

http://cgi.ebay.com/ebaymotors/ws/eB...tem=1853555718
this is the other gain

lmao did you have to ask? you just answered your own question!

Yeah....thats is for real...

REAL :bsflag:

:bs:

Ebay is really have a lot of problems lately with Fraud and this stuff does not help.

damn makes me wanna :piss:

look at the picture. i don't get it.

it would be nice if they had a picture of the actual product.

DON'T GET IT!!!
 

I won one on ebay, the guy has yet to send it to me, he's 'on vacation' ( I must have been on vacation!!!) DON'T DO IT!!!!
Spends the ten bucks on a used cd, a K&N oil filter or something you won't feel stupid a-boat.

Yes,the picture is ugly,but YES this product would work.
Your proteges are rough in cold starts because the air flow senses that the air is colder and enrichens the air/gas ratio..
If you find a way to get cold air flowing past this sensor all the time,the air/gas ratio will always be richer so performance will be increased depending on ambient temperature.
So basically this is something you could do all by yourself with a little handwork.

finally got it.
 

Ok, so I finally got the 'Throttle Body Bypass', and it's a resistor taped to an instruction sheet. You remove the throttle body sensor wiring harness, put this resistor inline, and that's it. I guess if you were going all the way with cams, timing, etc. it might be just the extra bit to set you over the top, but I can't really see it making too much of a difference with just my k&n drop in air filter.
bye bye $10 ;-)

You actually bought one!!!

Oh well live and let learn:D

But this thing DOES NOT get cold air passing the sensor. It makes the sensor THINK there is cold air present.

So it'll enrich the fuel mixture, but you're still breathing hotter air. Just MHO, but I'd think there could be a risk of detonation with this thing. Let the damn ECU work like it should - it gives the right amount of fuel based on the intake temperature. Adding fuel to air in an improper ratio is not going to increase performance. Extra gas without the extra air (well - extra oxygen - cold air is denser, and has more oxygen in it that hotter air) to combust that fuel is not "performance" - it's "bad tuning".

I love how in the auction he claims that you WILL somehow get cold air : What is this guy selling - a bucket of ice? You can't cool the intake air magically.

Don't do it. These things are a waste, IMO.

I love it! A bucket of ice :)

That's awesome heehee

Yeah - but the funny thing is that IS an old hot-rod trick - usually cooling the fuel, though.

Imagine a can, usually wrapped in cork for insulation, with a coil of metal tubing inside, and inlet and an outlet. You connect this inlie with the fuel line, load the can (usually called a "cool can") with ice or icewater, and your gas runs through the coil and is cooled before entering the engine. Kinda like a cheap intercooler for the fuel.

what would cooling the fuel do? Probably a stupid question.

Does the fuel contract meaning you get a higher density in the fuel, meaning a higher true fuel to air ratio? I'm no engine guy just curious.

I'm no engine guy either, but I do know that in general, heat is the enemy.

In a souped-up motor specially under extreme conditions, the heating of the fuel can cause inefficiency within the engine. Normal cars really won't benefit much from cooling of the fuel, because the engine temps are not that high - the engines are not run under extreme enouh conditions. And for the most part, the colder the air and air/fuel mix is, the denser the mix can be - meaning more oxygen and more (slightly) fuel = more power.

Like I said - it's an old-school drag racers' trick - just another way to reduce the temperature of the intake charge (the air/fuel mixture). I'm sure it'd work on most cars - but since it's an ice-based system, only for drag races ;). And plenty of governing bodies in drag racing have banned the use of the "cool cans" - or so I've read. I'm not a drag racing fan or anything, so I just hapened upon some info on the banning of the ice cans while searching around (for a picture of one, actually - which I was not able to find.)
