NOOO not at all Sharif... I know you mean well! Other people are saying they are trying to rip me off... Really? 160psi??? What could the issue be

 

Ok whatever...not so much blaming the shop as trying to explain that what you are saying makes no sense whatsoever. If the injector maxed out then it would have gone LEAN. Also the UTEC is designed to be tuned with whatever size injectors. If the map is right and they are scaled right, 380's should work fine without maxing out at 5k rpm. The whole thing makes no sense but I hope you get it fixed and are up and runnign soon.

 

Discussed on the phone.

 

Thanks once again Sharif... You are a True/ Honest Z professional, Great advice and has SOOO much experience!

NEW UPDATE*
Heres whats going to happen
They are taking out the engine monday, look at everything find problem and explain.
SINCE MOTOR IS ALREADY OPEN the parts going in
Wiesco Pistons
Crower Rods
ARP studs/ Hardware
and cleaned out everything

Approx time: 1 week

After, Tuning ONE map at about 13-16 psi 94 octane and see what happens.

 

Holy **** Trent... See... at least with 9.5lbs... I thought I have have a chance to at least hang with ya a bit you know...

now...

LOL!!!

I'll just have to take ya at the track with M@d $k1LL$!!!11!!!

 

One way or another, ur gonna end up with one schweet motor

 

hehe...I think you were looking for an excuse to build your motor anyways. Best of luck...hopefully it will be a BEAST!

 

LoL I wish... but Now I just have to bust my *** even harder to pay for this... which isn't to much fun lol because for the next couple of months I was planning on RELAXING!!!!!

 

better be ready by zdayz.

 

Lol you know it will be, it should be done this week! THE ONLY THINKG I AM EVER DOING TO THIS CAR NOW IS lol Brakes, Tein Coilovers with edfc, and MAYBE A T66.... and thats waiting a LONG TIME lol... never mind the two DEFI gauges I still have to buy.. EGT/ Fuel pressure... Damn man why Can't I just win the Lotto????

 

my boy ur goin big time

 

Interesting thread. What up bros? Hey Sharif, what's up? Any deals on a piston, rod, arp m/h stud, and jwt cam package? (I previously got the pistons, rods, arp h/m stud kit and more from you in the group buys but sold all that stuff to etx when he broke his motor).

I haven't been too active on the boards for a while, but can tell everyone that Godspeed = Tuning Factory really know how to tune a FI Z. My Greddy TTZ has been running strong for over 2 years now at just under 450 rwhp and all the work and tuning was done at Godspeed. I don't think it was an issue with the tuning, but more likely Trent getting anxious and going WOT past 5000 rpms when he knew he shouldn't. Just a guess, but that sounds about right knowing Trent. On a serious note, it will all work out Trent.

So I remain king Z on the Detroit streets, I think I'll wait til Trent's Z is done and tuned to see what power he gets, then its time to work on my Z to raise the bar. LOL

Sharif, can you PM me a price on the following as a package:
* Rods (Crower or Pauter - which do you think)
* Pistons (Arias or ? - which do you think)
* ARP h/m stud kit
* JWT turbo cams
* ATS triple disc with carbon treatment
* ATS LSD
Goal - likely around 600 rwhp (u think sleaves are needed at this power range if its a weekend/summer driver?)

Thanks in advance bro.

Yancy

 

you kids and your crazy WHP numbers... Dont you guys know its not about the 1/4 its about the lap times

lol jk with you Trent and Yancy! Cya guys around!

 

Hey Yancy! Long time no chat....hope all is well. PM sent.

 

My profesional opinion...
You motor is not blown.I am almost willing to bet that you drop in the newly rebuilt motor and the car does the exact same thing it does now..If your motor is blown then it was almost certainly done during the tuning process or you beat the **** out of the car and your not telling us.But based on the symptoms you describe you have an "ignition and fuel" issue.I would look at the injectors and the coil packs first..

 

Lol I See how it is Shawn!!!! The entire Issue is being resolved and nothing is left out of the equation. Shawn you should get you engine built right now....
you I need some competetion haha Jk. But you know I made 427whp @9psi at 5800 rpm we didnt even go to 7100 yet!!!!! So stock status I dont know if your the king!!! LOL

 

Something is very strange here. The compression numbers are fine. But that is only part of the picture. I'm a nobody, and I know a leakdown test has to be performed to get the whole picture. Performing a leakdown test will tell you what's goin on. Why wasn't a leakdown test performed during the compression check? Does this shop know what they are doing? A leakdown test takes 20 seconds per cylinder. The 180 on cylinder 5 is not proof of a blown motor as it is well within spec. Shop didn't know this?

Humm,
This by far the most varied and interesting thread I've read lately. Haven't
heard about the Autopsi of this engine after pull down.

The new engine must be almost ready for test.

It's a little difficult to read between the lines.

In reading the thread, some of the information stated does not "Add up".

Maybe because all the needed information was not stated.

Anyway, good luck on the Built Engine. With injectors and Coils operational
the fellow from MRC should not have any repeditive negative input on this build.


Good luck
Cheers Amy -

 

MRC is pretty balsy to make a statement like that. Number 1 the 380cc injectors were initially installed and tuned but went static at 5000 RPM. I spent some time dialing in all the part throttle fuel trims and the full throttle timing and fuel mapping. I only tuned it up to 5000 RPM and instructed the customer NOT to take it over that point since his wastegate was not holding any less than 9.5 PSI at any point in time even veting to atmosphere. Turbonetics wastegates aren't the best and we were running spring pressure so not much else we could do at that point. He left and returned in a few days but after he left he complained that his CEL had come on. When he returned we installed 550cc injectors and the problem started immidiately. We changed gaskets both upper and lower and also swapped injectors around to see if the problem was bad injector. We then changed spark plug and coil pack to see if that moved things around. Sadly no. Lastly we did compression test and found cylinder 5 to have 20-30 lbs less compression than the other 5. Obviously a cylinder does not lose compression just idling the car for a minute or two so the problem obviously originated at some point while customer was driving it with the 380cc injectors. I'm going to run a scope on the injector wires juts to make sure the UTEC is not doing something funky but I doubt it. As far as the MAP sensor tuning capability yes it is needed but only at high boost, higher RPM use which I have enabled and will be using with the 550cc injectors. I have been tuning a vairety of systems for years including Hydra, AEM, Motec, power FC, Microtech, Autronic and of course the much simpler UTEC. In fact I was one of the first UTEC AWD dyno centers authorized by Turbo XS. Next time think a little before you open your mouth to bash your competitors MRC.
