Is there a chip, supercharger, or turbo that will for an Automatic 2000 Ford Focus ZX3, 2.0 Zetec?
just one other question, if the Zetec ATX is rated at around 140, how is it that PW is able to offer a SC rated at 190hp & 170tq for a bone stock ATX? And supported by ZX Tuner, CFM, & McNews. PW tested this set-up extensively & found absolutely no negative issues before releasing this kit.SkaAddict said:^
The 4F27E (the ATX all Foci have been equipped with since 2000) has a maximum power input rating of something around 140...and a stock Zetec puts out 130. So the "facts" are that while with upgrades a stock ATX can handle big power, without upgrades you'll quickly turn your transmission into even more of a slushbox than it already is. And the Lentech? That's a fully aftermarket built automatic that starts around $2300. Keyword there is built...meaning it can handle a lot of power, unlike a stock automatic.
The PW/ATX kit is indeed available, check the PW web site & CFM & McNews has them on sale for about $3000.00. And remember the question that the person who started this thread was asking.SkaAddict said:A few things about the ATX Powerworks kit...
For starters, this kit hasn't been available to the public for more than a year at this point. They may have tested it to ensure that its not going to kill a transmission 500 miles down the road, but I seriously doubt they tested it to 10,000 or 20,000 miles, or for a few years' time.
Also, like I said its been de-tuned from what the kit is capable of. Less output=easier on the transmission. And as stated, its been tuned to go easy on the transmission during shifting. However, I would contend that defeats the purpose of having a forced induction system...the best time to mash on the gas is after you've changed gears.
I say 140 HP is the rated power input for the 4F27E because that's what Ford rated it at. Just like they rated the MTX-75 at 165. Now does that mean that you're automatically going to trash the transmission if you go over 140? No...but given the 4F27E's track record of giving up the ghost on a stock setup (and if you want to say I'm making shit up and its "not fact just conjecture" again, just do a search on it...there's several people on this forum who have gone through two or three transmissions in less than 50,000 miles with light or no modifications) its going to be much more likely to break down if you increase the power going in by 50 or 60 HP. Now there are affordable upgrades you can do to strengthen a stock ATX like the torque converters and recalibrated valve bodies that Ford Racing and Lentech sell that can be bolted into the 4F27E that will make a stock transmission able to go the distance with significant power increases. Its the same way that a stock Zetec cannot go much past 250 HP without needing forged pistons and rods and a CGI block...Ford doesn't put high-end performance parts on every Focus they roll out of the factory, especially automatic transmissions on an economy car. On average, someone who buys an automatic-transmission equipped economy car isn't going to give a rat's ass about performance modifications. The fact is, if you increase power enough into any stock component its going to break.
You keep referring to a clutch and limited-slip differential as if they're required...I can throw your "that's not fact its just conjecture" right back in your face. Several people on here have run turbo and supercharger setups on stock clutches with open differentials. The difference here is, a clutch is much easier/cheaper to replace than it is to replace or rebuild an automatic transmission and a limited slip differential is entirely optional. That said, at least with a manual transmission you have the option of installing a LSD...next time you're driving, cut the wheel all the way to one extreme and mash the gas. I can guarantee you that the outside wheel will spin while the inside wheel stays stationary...the same way the stock open differential in a manual transmission spins the outside wheel while the inside wheel remains stationary...the power takes the path of least resistance, in this case, to the wheel has has the least grip on the road.
Yeah...I said it hasn't been available for more than a year. They were showcasing it at JetFest last July when it wasn't for sale. Words are for reading...my point is the question of does their ATX tune really go easy on the transmission hasn't been proven yet. Its not like we're talking about something that's been on the market for three or four years, and there's a couple hundred of them that you can point to and say that they have a good track record. On top of that, I'd question the logic behind spending $3,000 on a supercharger that's only going to make 190 crank horse power...which on an auto equates to something like 150 at the wheels...I can put a Ford Racing head and cams on my car and have higher numbers than that N/A for about half the price.opus1 said:The PW/ATX kit is indeed available, check the PW web site & CFM & McNews has them on sale for about $3000.00.
