Boost pressure isnt really relevant to the problem. Engine torque is a much better indication of cylinder pressure than boost is. Not to be nit-picky, but I hate talking in boost psi when in itself its so irrelevant

True, my diesel truck has around 1200ft/lb of torque and 625hp. I only make 43psi of boost. I think the engine is 16-17:1 compression ratio. On the 5.9 Cummins the torque is real close to double the HP. Sometimes more. Playing in the diesel world, turbo drive pressure and timing will also effect cylinder pressure.

That's called steam cutting. Seen it a lot it in steam turbines that had a leak on the high pressure side. Looks like someone took a cutting torch to it.

In this case. When the head gasket goes. The coolant becomes steam from the flame in the cylinder.

I am just about positive the one cylinder I am down the cylinder wall has been torched straight to the coolant. LOL, that is why I haven't been all fired up to diagnose it any. It's a waste of time.

Spooler... Sorry to hear about your build going south. I just came across this today and was always hopeful yours was still running strong. We are still working on mine but taking our time. Just need to keep pushing the platform until we find a solution :driving:

Crap happens, I will get it fixed. I know which way I am headed. You guys will just have to wait and see what I do. By the way, I rarely get it right the first try. LOL Close, but no cigar.

Pick all the nits you want. Everyone that matters knows that you know what you're talking about and aren't just being pedantic.

What head gaskets did you use? Tq spec?

The next motor is going to be built by Mazworx. I have made my decision. I am excited and nervous. Waiting for the bank account to grow in the next month to kick it off. My money tree will be in full blossom by the end of February. I hope all goes well or I will be waiting a while longer.

Congrats!

Best of luck!!

Damn your money tree grows fast!!!

:iagree:

Yeah, I am gonna need it.

Interesting stuff.

Interesting! I was on a hub dyno once, very convenient to work with. When I went last Saturday I the operator did 12 second runs. I thought it was a bit long..

Info on the fuel filter setup that is on my car custom built by MA-Motorsports.

Here is more info.

WHEW! Missed that when I was at PRI. 100% getting that. Thanks for posting that information.

I'm so saddened to come back and read about your situation. :eek2:

It seems our platforms have little options left.. Believe me, I fully understand the pain of rebuilding! I pray that your new plan works out. There aren't many left that are still charging ahead. :tiphat:

Yeap, I feel like the Lone Ranger. I would be a liar if I said I wasn't nervous as chit. I have a month to get comfortable. I am going down a road that has had little success for some people. I got the best place to do the machine/Engine work. If I fail, I am done.

You are a braver man than I, Gunga Din.... GL

I may come out of wrench turning retirement for this. Still thinking on it. Just need to finish my garage and install a lift.

Hey Spooler, slowly but surely went thru and read this entire thread. Plethora of information here. I would like to add my build info to this thread to better aid fellow VQ guys in their venture for power and hope your next motor build is the last one you’ll need. I rarely post on myg37 let alone on here. I have a 9:1 comp closed deck block and o-ringed with FI 2.5 kit on E85 at 18psi 846.67whp.

Being in the military gives me little to no time to actually document/post my build progress at all. It’s a 2009 with only 31k miles. Shows you how often I’m deployed and get to actually enjoy the car.

Mr. Squeeze actually helped me out a bit thru a pm many years ago. Glad to see he’s back at it too.

Who's closed deck and what type of O-ring. In the head or block. Were your numbers on Ignite fuel and who tuned it if I may ask.

Ya sure, so it was all built at TSM. RJM closed deck block...all work engine wise was done at Jon Kaase Race Engines. They send all their insane GTR 1-3k hp builds their way. My dyno numbers were on E85. Guess TSM learned from the Z that was chasing 1k HP in the Atlanta area that had issues with his motor. Only time will tell if my build is “the one” or not. *keeping fingers crossed*

Oh and it was tuned by Taylor at TSM.

Just wanted to share all I can to help y’all moving forward.

I am not tryin to promote these guys nor am I sponsored, I’ve had a pleasant experience with em and just sharing info...Here’s their instagram pic of a block. https://imgur.com/a/VoZOFrj

And here’s a vid of the machine shop they send all their stuff too. Spooler I totally felt your pain on the waiting aspect. Took me over a year to even get my engine to start the process at Jons facility.

Another good video to watch. This may have been why my headgaskets cut loose. 700ft/lb of tq at 4550rpm. It is talked about in the vlog. Different engine but same principle.

3 bar of boost is 43.5 psi.

Tell that to my buddy who had them build his 1500whp gtr.

I don’t know what to say bro, like I said before I was just sharing what was done to mine. The more info out there for ppl the better we can gather data to see what works and what doesn’t.

You had that done to your Z?

To my G37 yeah...all major engine work was at Jon Kaase to little things like porting to assembly to the o-ring, and all the random secret squirrel stuff they don’t tell anyone about.

What happened to ur buddies GTR?

I remember you glad everything worked out car sounds like a monster.:driving:

Couldn’t get it right. Kept having issues with the shop. Now his motor blew and has to be build it. When it was right it was nasty.

How much power you looking to make, you doing any type of racing?

Damn that’s terrible about ur buddies GTR, that doesn’t give me a warm and fuzzy about my build.

I’m completely content on where I’m at now. I’m not tryin to go for the moon or anything. We stopped at 21psi bc I told em I didn’t want to worry about the stock upper plenum deforming. I did a lot of road courses when I was stationed on the east coast, VIR & Road Atlanta were my go to’s. With that Spooler definitely get the Stoptech BBK you’ve been wanting it’s great...brake fade on track days is pretty much non existent, best thing I ever did...well next to my KW V3s.

Now being on the West coast, currently in San Diego, a lot of my buddies do 1/2 mile events...which brought me into the black hole of the motor/twins build.

Spooler sorry if this is derailing ur thread never meant to, reading thru this entire thread I saw you talking about how no one really shares shiz on here about high power builds and felt obligated to do so. If you guys want more info pls just pm me.

All my funds will be going toward a motor build eventually. I am not too worried about the brakes at the moment. I am taking my time. The car may be garaged for a year. Who knows what will happen. I am not getting in a hurry. I don't want to do this again anytime soon.

Don’t be discouraged on how long it takes. It took me damn near 11 years to get to this point, bought the car in April of 2009. The long journey allowed me to learn from ppl to do the build I did now. Most importantly save enough for the build and a oh crap fund if anything happened.

LOL, do you think I am a rookie at this? The issue is not money, it is getting the engine to live. I refuse to pour money down the Black Hole. I am circling the MF'er now. You will find out when your time comes. Not one single car has lived long in the 750whp and up range if they are used as intended.

No ofcourse not haha, just some ppl give up and go to another platform. Which can be understandable at those levels the VQs are questionable.

Side note my best friend threw a rod on a IPP stage 2 motor, granted he was hooning/drifting it a bit so that probably lead to its demise. This was about a year ago, he’s waiting to see how this motor is before doing another build. Told em to go cough up 50k and go billet everything.
