ban25

Isn’t it pre-corrected? The chart says SAE 1.23...

Yup pre-corrected. You dream crusher you!! So let me down my crank estimate to 400 ish? %20 drive loss makes it 402.

That is pretty darn stout!

Great work!

What tune is on it?

The correection factor takes care of the elevation and weather if the dyno calibration and set up is done correctly.

SurfDog

I'm no dyno expert. It could be altitude corrected, I wouldn't know. If it is, I'm about 20 hp shy of what I would expect based on my build.

Either way, the motor "feels" strong and is pulling *very* well compared to other vq37s according to the tuner. The number on the graph is usually considered less important than the move from baseline which was about as expected from the rebuild so I'm happy with the results.

UpRev or ECUTEC?

See that 24.62 inHg? That is very low atmospheric pressure due to local elevation. The lower the pressure the higher the elevation. So, the correction factor increases your results to correct your numbers to std.

Here in OK at 1250 ft elevation, pressure runs between 28.5 to 29.5 in Hg.

Std pressure (sea level) is 29.92 inHg, so you were definately in some "thin" air!

SurfDog

Standard day is 29.92 and 15 decrees C.

Why did you go with IPP anyway. Everything I have read in my research is their stuff is not that good.

SurfDog

Great question. I have heard good things about the shop, and this story is still not over. I”m hoping IPP will make this right. I’ll let you all know how it shakes out. I hope to hear back soon about what their idea for the next step in getting me up and running is. Pulling the heads and shipping them back is probably not a viable option just due to labor costs. I will probably have to have the lash redone locally.

I understand stuff happens, and I think they are good guys down there. It will be interesting to see how well they stand behind there work. Like I said I’m reserving judgment. They may yet come through and make this right.

It has been quite a voyage so far trying to put my blown Motor back together.

Update. IPP is backing their work as I hoped they would and has offered to remedy the issue by paying for a local shop to do the relash.

So... all good. A bummer to have to jump through hoops but stuff happens and they are making it right so I say all good.

I’ll post new Dynos when I get them.

BTW some shops cannot reassemble the head of you take apart the VVEL system. Some can. Nissan japan can and I have spoken to one shop (maybe the only one) in the US that can but most shops can’t so BE CAREFUL before you disassemble a went-boom head for shipping as a core. PM me if you need more info about this.

Or you can just send it to MaMotorsports who came out with the product

SurfDog

It’s already mounted up on my motor and installed. Dropping the motor taking I all apart and shipping is a worse option.

Oh you mean in general? Yeah, that is an option.

The guys at MA have been very helpful as I go through this project.
