Does anyone know what gear the car was in? It seems that 3rd will be the weakest, but most people will dyno in 4th.

I'm not trying to start s***. I've read through this entire post trying to figure out what the hell happend. I see these cars blowing up by the car carrier load, so I'm trying to figure out what the hell is going on.

He is not mistaken i was there I saw the dyno sheet we actually have it PM slug420 ask him to scan it we took it after brian left.

That still makes little to no sense because that would say that at 17 psi he was on pace to be over 400 horse... keep in mind that when Patrick (pdhaudio) was just dynoed at 15 psi they hit 296 peak.... with a bigger turbo and a full worked motor (conservative tune thouhg). If he held that torque to 4500 rpm's, he be at 356 horse, and if he held 90% of that to 5500 rpms he be at 392 horse. And I expect his torque to be at 90% or higher... and those numbers are FAR higher than others near that psi... It's not completely unreasonable, but it SEEMS optimistic.... but it could be part of why the motor failed, something was going on to squeeze that much out put out of that thing.

well according to dyno sheet he made 1200 tq

sounds like there was a "stock appearing" swap to a Cummins Diesel to manage that .

I know nothing about that. He said he modified it. LOL

they say engines run their best right before they die lol

I will post pics. up later tonight of my disaster. No valves hit any pistons. The only thing I can think of is the pistons rocked in the bores and broke. Again, no detonation marks whatsoever.

I didn't get a copy of the dyno sheet. I was only going by what I looked at, at the dyno. I could have sworn I saw 263whp at or below 4200 but the guys that actually took the dyno sheet told me it was more like 3300. Either way it was doing good...until.

I believe pdhaudio just had the bottom end done. I don't think they touched the head. I did every trick I knew, and some I didn't. What it put out doesn't really matter at this point. It is still a pos, and slow.

My last one didn't.. rich.. misfiring... being weird.. then rocks in a blender and "oh s***, smoke"

ow. i hope i never face that.

 

[TurfBurn]

I'll dyno up in about 3 weeks... I'll run a 10 and a 13 psi dyno most likely.. maybe a 15... and some checks of the VICs.... I did everything I could come up with to the motor... so we'll see.

Either way.. it still sucks that you lost the motor and none of it is good either way... if you got those numbers that is absolutely kick ass.... but obviously with all the tradgedy of the dyno it is hard to know what all went on.

The only thing I can think of is the pistons rocked in the bores and broke.

The rings probably got toasted when the engine over-revved. Our longer stroke means very high speed piston movement. They then could have destroyed the pistons...What piston/cylinder clearance were you running and what rings did you have?

 

[BlkZoomZoom]

I have no idea what the piston/cylinder clearance is. Thats one thing I didn't/don't have the tools to acurately check. I am thinking it was alittle too much, and once you see the pics. I think everyone will agree. The rings were the cp ones.
However Cyl. 1 broke before going on the dyno, maybe during the 140mph jaunt that I did on the way to the dyno.

 

[ddogg777]

You mean we will be able to tell by the pictures that the clearance is too much? That isn't good...

 

[Focus]

If there was too much clearance it would have sounded like a diesel truck.

 

[terbow]

hey! i see my sig there mr. focus, thanks for askin. canadians, i tell ya

j/k BTW

 

[BlkZoomZoom]

Thats not what I meant. I meant by the way they broke....Anyways here we go with the horror show.



Cyl2. 3. 4. and 1. Maybe 1 didn't get any fuel?
