My Car is on the DYNO right now. So far...

Ltlhomer and Turbobuick,

I like both of you guys and I really like both of your cars. In fact, if they are ever stolen, you may want to check my garage first (even though I'm a pastor...the Lord is forgiving, right?:icon_mrgr ).

However, you guys need to keep your on-going pissing match out of my thread:wink:

I want to read responses that are helpful to the challenges that I am facing with this Ford PIECE OF CRAP!!! (do you sense my frustration at this point:icon_eek: )

Both of you guys know what it is like to be frustrated with your car, so I know that you'll both understand where I am coming from at this point.

Thanks guys,

Dan

You got it homie. I'll delete my junk as well as this post in a few minutes.

Dan,
What kind of wastegate/boost controller are you using?
Click to expand...


The wastegate is a Tial 44mm. The boost controller is just a manual/vacuum controller that came with the kit. I'm thinking that I just might order some springs from Tial (or if someone has some that I can borrow???) that would up the boost via the springs.

On Tial website, they show several combinations of springs that will enable my wastegate to make 15, 18 and even 20lbs of boost based on the spring combinations. If I put those in and the turbo produces more boost, then I will know for sure that the boost controller is not working correctly.

Any other thoughts?

Dan
 
You guys are not getting it, springs will not give you more boost, the wastegate isnt opening now with the spring that is in it. The turbo is maxxed out. His heads flow great and his cubes are up there. PSI does not = power.

Dan, dont take this wrong but : stop messing with it and take it to the track. Will the boost numbers or dyno numbers mean anything if it runs a bottom nine ? NO.

I mean at 12 psi i made 560 hp and 750 lb ft. Its just a number on the dyno and means squat to me.
 
I dont believe in dyno numbers, I do believe in using a dyno as a tuning aid though. My buddys car made like 480hp at the tires on a mustang dyno, yet went 10.0's@135 in a 3400lb car.
 
I was using rodriguez's wastegate when i first started tunning my car...it made 22psi@5600 RPM's....way to much for my fuel system. His wastegate has a 17lb spring.

I threw in my wastegate with a 9lb spring and ended up making 15lb of boost (it would creep as the rpm's went up, but maxed at 15).

I dont have a boost controller.

It looks like your turbo is rated to 900/1000hp? How were you verifying the wastegate was never opening?

I say try the springs. They shouldn't cost much so if it isn't it you're not out much before trying something else.

On my set-up I get about 21psi at the top of 3rd. If I wanted to go too much higher than what I'm at I would have to get the stiffer spring and let that do more work and turn the boost controller I have down. If I were to go up to 23psi or more I'd definitly be doing it.
 
Yeh how are you verifying wastegate isn't opening? Run your reference line to just the top port of the gate and you can be sure it's not opening then...just watch the boost in case it really just wasn't opening because then you will see how much power that turbo will make. Do you know what your iat's were through your dyno pulls? Those can tell you a lot of things as well if you have something to compare to.
 
OK, last night I spent some time playing around with the wastegate. I actually disconnected the vacuum lines from the waste gate (I plugged them up so that there would be no vacuum leaks) then took it out for a spin.

Well, with great care I began getting into it while watching the boost gauge very carefully... I discovered - this turbo won't make any more boost on my motor. 13-14lbs is it. I was hoping to see the gage go up to 17 or 18lbs, but it just wouldn't go there.

Dan, your hot side exhaust pressure is overpowering your 10lb spring. If you put a pen spring in there you wouldn't expect to see 18 lbs? Try to find the correct springs today for 18 lbs because it's the cheapest fix.

Sean,

I'm still mystified as to how so much green water ended up in the catch can. But still, there was ZERO water in the pan. Weird, huh?

I've heard the same thing about the cometics. Only thing is I didn't have this problem at all last year and the year before with Cometics on my old combo. Anyways, I'm going to relash the Rockers this weekend and will definately double check the headstuds as far as the torque issue is concerned.

I put new plugs in it and it seems to run smoother now, but it still seems to be running a bit rich on the bottom end. I just think that the injectors might be a tad too big...:dontknow:

I want to bring the car back up to fix a few small issues that I'm having such as - line lock doesn't work and a few other items like that.

Thanks for your help.

Dan

Line lock isn't working ?? we checked it twice Maybe the tire failure knocked some wiring loose ?

Yeah i had talked to Ron about the plugs loading up what were gonna have to do is street drive it a bit and find the errant fuel cell/Cells that are overfueling. I went back through the file thats in the car and i don;t see anything thats really out of whack but those big nozzles might be having some linearity issues at very low load/rpm.

I have video of the car making a pull somewhere and the gate never once opened.
 
Dans wastegate is right up front, they had to move the dyno straps way over so it wouldnt burn it. I watched 10 runs and it NEVER opened, so the backpressure is not opening the wastegate.

Then I'd say it's safe to assume he's outta turbo...a 76 is pretty small for the badass bullet that he has trying to huff through it.

Dan , i agree with homer. ( waiting for the lightning bolt) Even if it is out of turbo, its going to be a rocket ship. It sounds like you have a definate 9 sec street car. Just enjoy it !!!!!!

Why are they worried about burning straps when it never opens? Next time he does a pull put your hand on it and let us know if it opens. You can't tell someone that is running a similiar turbo to Raj's turbo that he is done at 14lbs and 200 plus horsepower less.
