New product from EP!!!

Our good mates over at european-parts.net have got me again. Just found this:
http://www.european-parts.net/catalo...roducts_id=881

Seems like an extremely worthy investment. Liking the sound of that mid-range torque and high end power increase. Think of this, along with a CAI, :eclipsee_ !!!!!

What do you guys reckon?

Good find...and the price isn't so bad either. Looking forward to the gains these produce!

I reckon yes! Thorttle body could give the car just that extra edge!

photn · 19-09-2008, 06:06 PM

be a bit carefull atm. i have ordered 2 things from EP in august 4th and sascha is saying that my order does not exist and i have not recieved the goods yet. so i dont know if there is a problem with his software cause everyother time his service has been good.

Engineered with a 4130 chrome-molly throttle shaft supported by sealed bearings for heavy duty use and an ultra thin throttle plate with dual return springs for smooth operation. Anodized in Cosworth Blue.

*licks lips*
Expensive though. Damn Cosworth!!! Where does the MAF sensor fit on that 67mm one though, that's my only question. Can it be removed from the current one and refitted onto that one?

Loving the blue though. The price is a put-off though. Given the choice, I'd probably have to go the EP one, just because of the price, and the 7mm difference doesn't make up an extra $300-400 by the time it's shipped..

7mm is a HUGE difference in flow rates, but to be fair, the standard duratec probably couldn't drink anywhere near enough to warrant it...it'd be interesting to do flowcharts on the inlet system etc...but kinda pointless :P Just boost it....that'll shove air thru ANYTHING :P

RJO89 · 19-09-2008, 11:23 PM

Yes, but boost also costs a lot more to install, plus it'll wreck the tranny in no time. In an ideal world though!!

BlackLS · 19-09-2008, 11:25 PM

The cossie tb looks like its cable operated for the US duratec engines.

melbzetec · 20-09-2008, 07:26 AM

It would be nice to see some proof of what the gains actually are. On the LR Focus, you can buy a 65mm throttle body, but it gives virtually no gains in power or torque...just a change in throttle response.

RJ809, maybe you need to be the first guinea pig!

Mullett · 20-09-2008, 03:40 PM

Disclaimer: *rant ahead*

A much simpler option (and likely cheaper as well) is to have the standard TB bored out and a new butterfly installed. This way you keep the factory throttle control, build quality, appearance...etc. I'd want to see dyno proof that it makes more power though...

The flow rate of the TB shouldn't be the limiting factor in the intake system. You will get sharper response (because for every degree of throttle movement you're letting more air in), but all you're doing is moving the 'dead zone' (where you're increasing the opening of the TB, but the engine has reached the maximum draw for a given RPM) to a lower percentage of WOT.

EG

Engine at 6000rpm, free draw 200cfm
a) 300CFM throttle body (assuming a totally free-flowing intake)
OR
b) 400CFM throttle body
OR
c) 150CFM throttle body

At 2/3 throttle with 300cfm, the engine is consuming all the air it can, so opening any further won't actually give any power gains
OR
at 1/2 throttle with 400cfm, the same scenario
OR
at full throttle with 150cfm, the engine is being restricted, so a larger TB would increase power

So unless the TB is creating an inlet restriction (150cfm TB in the above example), there's no power to be gained by a bigger throttle body, just an increase in sharpness and a decrease in throttle control. Of course, turbulence and other factors in not having a totally open throttle change the results as well, but as far as the example goes it'll do

What I'd be really interested in would be a cable conversion, the drive by wire throttle is very doughy...has anyone come across anything like this being done?

Re: Boost. Yeah, it's expensive, but not outrageously so. A turbo kit should be around 3k, with an aux injector controller so that you don't have to mess with the factory ECU, and on moderate boost it shouldn't sacrifice reliability. As for $ v gain, there's no contrast...the throttle body would be $400, for maybe 2-4hp, where a turbo setup would be 3kish, for 50+hp, and a massive increase in midrange and driveability...just my opinion, every now and then I open the bonnet and wonder if I can get an Eaton M90 in there somewhere

I'd have to say Mullet, that is one of the better (and rather intelligent) rants I've ever seen on here!!

melbzetec · 21-09-2008, 08:17 AM

Take a look here:

eXtremist · 21-09-2008, 06:32 PM

This looks exactly like the CROSWORTH throttle body but its much cheaper.

According to the reviews on the focusfanatics forum, they have said this throttle body provides better response compared to factory, but will it suit our electronic driven throttle bodies?

Mullett · 21-09-2008, 10:35 PM

I wouldn't expect it to work with the fly-by-wire, "Features a sharp-looking, billet throttle arm" sounds like it's designed for the cable, unless by some chance of simplification they use the same TB for the two styles and just bolt different bits on...On our Duratecs, is the TPS seperate to the stepper motor for the throttle control? Or is it integrated in one unit? (I just can't be bothered going out in the cold to look :P)

But, in my opinion, if you want throttle response, a cable throttle conversion has to be cheaper, and would be 100x more effective, than a larger TB, and you don't loose your throttle control.

eXtremist · 23-09-2008, 11:15 PM

I'd rather change my throttle from electrical driven to cable driven, I'm not a fan of the delay.

Mullett · 24-09-2008, 07:22 PM

Second that. Maybe I'll have a play with that this weekend.

How'd this go?

Mullett · 29-09-2008, 01:33 AM

I got distracted by girlfriends parents coming down for the weekend :P I'll try and have a go at it next week, but i'm not hopeful...at the very least, I'll need to make an extension for the throttle pedal, brackets for the cable glands, and a lever for the throttle body...and that's assuming that the TPS and the stepper motor aren't one unit...that'll make life tough...

BlackLS · 29-09-2008, 12:52 PM

Nice 1/4 mile time

Mullett · 29-09-2008, 01:20 PM

It's damn consistent! Ran 16.050, 16.045, then on the last run I stuffed the launch and got a 16.099. I still want a 15.999999999! Just because.
What's normal for a LS/LT? I've only done the basics, airbox and ignition timing...

-RM.

Mullett · 12-10-2008, 03:16 PM

Update on this: I took my car to BPT motorsport on friday and had a chat to them. They've offered a flashtune of the standard ECU, apparently good for 15ish hp and better economy, so I'll get that done next week...if it's good, I'll let everyone know

But, more interestingly, they can adjust the reaction of the fly-by-wire throttle, which would be just as good as the extra power

Stock as a rock I was doing 16.2 first run, then 16.5 next 2 runs. That was stock intake, timing. Was also on bald NCT5s
