Time for a TKO!!!

you can only pound a 700r4 so much and they die hard

bad luck today, killed the trans.

Haven't torn it down yet but i think i broke the output shaft. I have it on video and a datalog.. will post those later on.

[Superdave]

Yep, i just couldn't get used to the commander 950's software. I'll probably sell it this winter.

[Alxsmt]

did you move back to the 7730?

[ericjon262]

Both.


The slash cuts are right after the X pipe on each side, and they run up to the old PCV and vent fittings. If you take one of the lines off the valve cover and stick your thumb over it there is a vacuum for sure, you can stick a piece of paper to it.

awesome, that's what I needed to know, mine plan isn't to pull a vacuum on the crankcase, but just to keep air moving and my oil clean.

do you have them hooked up to both valve covers or just one?

[Superdave]

Yah, that's what it read before i started the engine. At idle it sits between 88 and 90, really not much change there. high RPM when the exhaust is really flowing should make a difference but we'll see.


the old school guys claim 2-5" of vacuum produced by them, i just don't see that happening.

[robertisaar]

93 baseline meaning 93kPa barometric pressure?

[Superdave]

nope, i did datalog some quick WOT runs up to 5K or so today, crank case pressure hit 99kpa with 93 as a baseline so i'm pretty sure the slash cuts aren't working all that great. The cutouts are closed but the exhaust is extremely free flowing... I'll know more tomorrow after a few runs down the track.

72F and overcast.. can't beat that.

[ericjon262]

cool, LMK how well it works! did you put a catch can on it yet? I'm willing to bet it would solve your oilsmoke problems!

[Superdave]

got rained out, weather looks good for this Sunday though!

I wired in a 2 bar MAP to monitor crank case pressure, it'll be interesting to see if the crank case evac setup actually pulls a vacuum, and what if any difference there is between having the cutouts open vs closed.

Still working the bugs out of a BFAU based tune (latest and greatest $A1-Auto binary). Finally going to be able to use the launch mode settings to try for better 60's

[ericjon262]

alright now, you said you were going to the track Sunday, Sunday was 5 day's ago!
