325whp 320 wtq STOCK ZETEC - UPDATED #'s 457whp/450wtq! > New thread linked..

[Ja-Red]

The car is idling great! I just kept the tune the way it was just to get the first 2 heat cycles on it. I just adjusted the fuel psi until i got the AFR at idle right. I am off work tomorrow and first thing I have to go to the junkyard to get a bolt I snapped and that stupid little clip that holds the slave cylinder line. I specifically remember putting it somewhere so I wouldn't lose it... guess what, I cant remember where the **** that was!

I would like to have the car tuned by the week end but only time will tell how it is gonna play out. my initial thoughts are telling me that it is gonna be way easier to tune with the return fuel system. It just eliminates one variable and I no longer have to worry about the fuel psi falling off at high boost and rpm.

[pzev04boy]

If you can't find any cars with a manual trans, fyi the clip from the brake fluid reservior to the master cylinder on a focus looks a little different but works perfectly for the slave cylinder.

[illinipo]

yeah that really sucks... I have a few spares of those in my toolbox from various builds/swaps just in case i lose one...

[Ja-Red]

I put a few miles on the clutch today... then pulled it straight on the dyno!

I still retained basically the same curve (I didn't expect that to change without a new intake anyway) but picked up a few hundred more rpm spool up. The compression is 195psi on the gauge which is what the car read pre-turbo. So the gains I made are all from the head. I also changed out the spring in the wg for a stiffer one and it runs about 14psi on spring. I have to admit the first couple of pulls I was disappointed in the power. I was only seeing a 5 hp gain from the head. Then I took a closer look at the data logs... 8 degrees of timing! So we got the timing and AFR back where it was. Tuning the cams only gained 3 or so hp peak (5800) but we gained 10 hp at 6500rpm.

Now since you are dying to know what number I ended up with, first, I must say that I think I fryed my boost controller solenoid when we were trying to start the car with the battery charger. It was really acting up so we never turned the boost up. Hopefully we can do that later this week.

Anyway... I ended up with 305whp and 302wtq @ 14psi! That is at least a solid 25whp gain from the head! The car is much more consistant with the return fuel system and it is working great!

This is a great place to start and I don't think 400whp is gonna be much trouble. If you do the hp per psi I should hit 400 with about 22 psi.

[polarisman14]

^^That sounds awesome--is that 400whp 22psi estimate on 93 octane or what? What timing are you at now at max load? Charge temps? Also keep in mind once you get into higher boost levels the hp per psi generally starts to fall off somewhat linearly. Not sure of the specs of this particular turbo but I would think around the 20psi mark it'd begin to fall off?

Congrats on getting things together so quickly. Looking forward to seeing more clips and vids...You gotta take a ton of them once it makes a mockery of third again

[bmylez]

Even if the hp/psi ratio drops off a little, looks like he can hit 400whp on 25psi. Not too shabby . I just don't understand how Honda got their engines so damn efficient. I've seen multiple vids of stock K20s put down 420whp on *9.25* psi. What the hell, seriously. They are running equivalent to a GT35R, so it's pretty big, but not ginormous.

Good luck with your high hp quest, Jared

Sounds bogus to me considering that motor is only moderately better then the zetec in my belief that is sounds to me the k20 isnt really stock.

[bmylez]

Hahaha, are you serious???
K20 is moderately better than the Zetec? Not sure where you get your info from man, sorry. AJP (All Japanese Performance) has multiple legit vids of stock motor K20s putting down those numbers. They can't advertise those numbers and then have customers not putting down the same numbers. Believe me, it's for real. K20 pwns all 4 cyl, plain and simple. AJP ran in the 11s on a stock motor.

Oh well lol dont reall like jap crap

[Ja-Red]

9 psi sounds like a stretch but no so out there. Lets not go down that road in my thread please.

I am actually thinking there will be a bigger jump around 16 psi just looking at the way it did from my many dyno pulls and now thinking of the increased flow from my head. But we will see.

It is funny you should mention the k20 because the guy building my new turbo said one very similar made over 500 whp on a stock k20 @ 16psi.

I've always not liked jap engines cause yeah you can make big numbers but then you have the reliability issues but of course getting another engine isnt really a problem since theres a **** load of them out there and their cheap cause of that reason.

[bmylez]

Truth. Same guy who put down 419whp @ 9.25psi put down 514whp @ 17psi on built motor.

Yeah, it makes sense that the turbo will get into its efficiency range a little higher up. You had it custom built...so is it kinda like a GT30/35 hybrid? The guy to beat is someone on FF who made 446 @ 28psi . I believe in you!

[Ja-Red]

No this is still the 3076r but I am having a custom one built something like the 30/35 hybrid.

[turbozeteczx3]

Damn some good numbers for such low boost. and did you run your lines out of the stock hat on the fuel pump

[turbozeteczx3]

o ya hey what size rims did you run when you went to the track and what kind of rims were they

[Ja-Red]

They were 15x7 with old 225-50 bfg drag radials. The tires are old ones bryan had laying around that he traded someone for. there is no telling how old they are, atleast 3 years old. The rims are some cheap aftermarket that I traded my stock wheels for from KStyles @ massive.

And yes there is a bulkhead fitting in the tank hat/lid for the feed and the return used the stock line I just flipped the filter around backwards for now.

[ProjectSedan]

Ja-red, you have pics of the fuel return system? Im kinda interested in to see how you did this.

o ok cool ya since i have the Big Brake Kit i need to find some 15X8 witha 6inch backspacing they want 330 a rim at bogart wheels

And ya fuel setup sounds like a good one

[Ja-Red]

Why do you need 15x8?

If you find some 7" that work I know somewhere that widens wheels for 75 a piece.

For the fuel system, I still haven't filled it up yet to see if it leaks. It shouldn't Like I said this is not the first one I have done like this.

[turbozeteczx3]

LOl 15X8 cause im gonna run a big mutha f'n slick lol 1.6 60fts should help and its not that in need i wider wheel i need the extra backspacing to clear the calipers

and where are the carnage pics of the old engine

[Ja-Red]

Iv'e been so busy with the re-build I haven't had time to tear down the old one yet.

[turbozeteczx3]

lol its understandable

[Ja-Red]

Just a little teaser

12 deg of timing 21psi 93 octane not done yet!

LOOK AT THAT TORQUE!



Hopefully i will have a chance to finish tuning tomorrow. Then throw some octane at it for a number.

Oh Yeah, The torque is at 4k rpms bitches!

[bmylez]

Giggity. "And I...jizzed in my pants" . That torque is off the hook. Granted, it's no 570whp beast like in Puerto Rico but....naw, j/k, your car is awesome. So how much timing you gonna run with C16? Also...try 30psi and see what that gives ya . I think you're going to approach the big 5.

[Ja-Red]

500? I highly doubt it. The turbo is already out of its efficiency at 20psi and the cams and intake are now the limiting factors. I'm not gonna run more than 25 psi anyway. It will be on 110 octane c16 is wayyyy too expensive like 12-14 a gallon 110 is only 7-8. 110 will be plenty.
