I would stick with batch fire for about 20 reasons.

Brian,


D'oh! I just ordered the order coils as you were posting

Never mind so :lol:

Just try keep the extra set of coils cool, 6 is bad enough, but 12 is 6 more potential failures.

Had loads of these fail if placed anywhere near the rocker.

Brian,

COP coils or the ls1 type which still use wires?

OE rubber is fine. I've seen some data showing that it's just as stiff in terms of volume growth per psi as braided stainless, and requires MUCH less maintenance...


You need to check in more often....the new lines will be here any day.

I have to say though that is almost shocking info. I've done SS lines on a couple roadrace bikes and the difference in feel was quite dramatic both times....this was mid 90s though so maybe more modern OEM lines have improved? Or maybe the car lines are different from the bike lines in some way?


You're making too much progress for me to keep up! :P

Oh fine... here's test data:

http://www.gotyournose.com/goodridge/us ... rubber.pdf
http://www.superstreetonline.com/how-to ... s-upgrade/

Everyone seems to be quoting the same Goodrich data, but I haven't found the original source...
However, here's rubber hose that claims 0.06 cc/ft expansion at 1000 PSI.

http://www.veyance.com/productsdetail.aspx?id=17048

Per the supposed Goodrich data, a max effort stop with close to 3000 psi line pressure will have approximately 1cc of brake line volume growth with 4 feet of rubber line in the system. You know your MC diameters and pedal ratio, so you can figure out what that translates to for difference in pedal travel.

Brian,


Brian, heat is the enemy of all transformers and coils. Internally generated heat as well as engine heat. When you double the duty cycle of a coil as you do in waste spark there's less time for cooling, particularly at high RPM. Waste spark destroys coils faster than sequential, unless they're wound for it. High BMEP, high RPM and waste spark aren't a good combination.

The coils I was planning are wound/designed to do what I was planning mostly.....so really LS1 coils and direct fire leave me in about the same place wondering about 9500 rpm :?

But at least I'll lose cylinders 1 at a time this way...I probably won't even miss 8% :)

@ Mark, the ones that use the wires.

@Cribbj, yes indeed, that is true. Im wondering if Marks injectors are big enough to now run in sequential mode given that they have to deliver the full dose in one shot with seq, and not two as with batch.

Im sure they probably are...?

@Mark, I cant remember, but have you a hall sender on the cam? You will now need it wont you?

Brian,

Brian,


The fuel was always going to be sequential and the injectors are PLENTY big with the planned duty cycle at around 35% to create a pseudo-DI effect to make lots of HP...or at least that's the plan:)

I'm trying a little VR on the cam that fit neatly.....hopefully the ECU can read it at cranking rpm...it looked fine with the trigger spinning in the lathes so......,

I did a little shopping today.
I'm adding fuel pressure and temperature sensors so I those are coming.

I also finally decided what I want to do is the analog inputs I have available..... NB02 on each cylinder. These will read pretty well from maybe 13.2-13.5 down to maybe 15 pretty well so I can tune idle to at least 80% full power on all the cylinders at once then just carry the corrections forward to full power and tune that with the WBO2 in the collector. This will make perfect idle and cruise much easier to achieve I think

under $25 each on amazon:
http://www.amazon.com/Bosch-15703-Oxyge ... 5C79TXHX2S

bungs with plugs under $9:
http://www.amazon.com/Innovate-Motorspo ... ds=O2+bung

A pretty cheap way to get a lot of helpful data. This will give me WB02 in the 2 collectors and NBO2 on the tubes unless I see something weird then I can just move a WB to the tube of interest and see what's going on.

I got the wheel speed chopper wheels drilled and deburred tonight...pics when I get a chance to install them.

i also got looking at the brake line adapters...some will need to be modified it looks like but then they'll work I think. so I need to get the calipers on!

as promised parts installed.


edit - just realized I'd posted 2 of the same pic :oops:
