Ahh. 9:1 and 10:1 are very different.

I have been repeatedly surprised at how much power there still is at 10.8:1 on many applications if the ignition system can handle it. It gives you a lot of ignition timing leeway.

 

I like your style!

I'll post my next round tomorrow as I have off from work.

 

i use to have some pigs!!

Got behind on school - I'll get around to it this weekend I am sure, but college needs to get done today.

 

^True, something important, indeed! Anyways, when you are caught up, don't forget to post when you are finished, I'm still trying to "grasp" everything that has beeen said.... haha

 

Updated Post 2 with my Baseline Findings. I'll do another round tomorrow weather permitting.

 

Just noticed this in your first post .
Both my apex failures were at the point where it necks down for the two piece design . One piece seals should be much stronger and get over that issue but at the expense of idle quality .
I don't see the inferior sealing as an issue at high rpm .

Is that how you see it as well ?

 

Yup.

I'll take the hit on idle quality and MPG / emissions...once I get past 1500-1700 RPMS, it's game on.

 

As we both know 8.2 is very possible, and that BHR Ignition System will still spark the car up!

 

sounds like a cunning plan - now make some powa !!!!

Also - makes me wonder why the Esmeril seals are 2 piece .....................

 

LOL - yeah we do.

I am guessing they are 2 piece for the same reasons the OEM ones are 2 piece.

Something interesting happened today - while making my first boosted runs; I never got my load above 100% and my MAF was at 3.71 V only.

Granted I wasn't boosting hard, but I got to 100% last time for just a quick second Friday.... any thoughts from the other Hymee guys..... is this a bug?

 

car sounds really nice dude

 

yep - i've seen it a few times . Don't know why it happens - just read 100 as 200 and that will give you the correct load .

 

What! No way I am hitting 200% load.

 

well that is what happens with mine every now and again - it reads 1/2 the load it should and I think the only time it does it is when I break 200

 

if I'm understanding the problem correctly it is a bug left over from the dude logger days. if you drive round without boost for the first log the system assumes you are NA and wont report the load correctly. to solve it you need to start a new file"vin" and hit some boost for the first log you download.

 

I'm using the Live USB to log if that matters?

I can reset it this evening and see if that helps.

 

Unfortunately your particular situation required installing the engine new and breaking it in as FI. Had you been able to break it in on an engine dyno as NA first it would have allowed completing the break in sooner under more controlled conditions. A highly experienced Renesis builder would already have a known safe map with intake/exhaust components already setup for the dyno. The break in process runs the engine for many hours with increasing rpm increment points.

It takes much longer to break in ceramic seals and now your conundrum is you can't operate at higher rpms without also incurring boost. I suspect you're going to need a LOT more miles than you presently have under those conditions before those seals start becoming efficient. Any tuning you do prior to this is likely to require rework.

Otherwise great thread.

 

I'm not taking pot shots at the builder so let's not go there. I was just trying to explain myself.

Did you use new rotor housings with the seals?


.

.

 

You got usb live to work ? Amazing !!!! I have tried several times without success .

 

Interesting thought; I think the tuning of the VE map will need rework, but the sensor and injectors are what they are... so I am hoping things will work out ok for me. Though it will be interesting to see if a pull more and more vacuum as time goes by - that would be cool, since the only thing I don't like ATM is my idle.

One new housing.

Yeah man - it works great, set up my live gauges, and then log away. Minues the calc load thing....

 

Good read Kane, keep it up man!

 

When do you think you'll post dynos?
