installed e-force S/C--now have "perceived"oil usage issues

Recently, 3000 mi ago, installed a #1572 E-Force (Edelbrock) Supercharger to my 09 Z06.
Dyno nos.were excellent, 603 rwhp and 560 rwt (also had Kook 17/8ceramic coated headers and X-pipe and a good tune) Multiple dyno pulls and tuning adjustments to attain these numbers.
A few issues...wondering if some of you folks who have E-Force S/C's on LS-7's, have comments.
1) Runs hotter now. Prior to E-Force install ran 178-185F on highway and 192 to 205F in traffic...now 183-201F on the highway and 192 to 219F in traffic No biggie here (BTW am running a 160F T-stat) BTW adding two bottles of Redline "Watter Wetter" helped about 5 degrees F.
2) Other issue concerns me....In 3000 mi have used (added) 2 quarts of oil....in this case Royal Purple 5W-30synthetic although I had changed oil w/Amsoil 0W-30 Signature series Synththetic after install. Never used any oil prior tothe S/C install. Oil pressure 65 + cold and 52 psi at 190F oil temp on 95F ambient Temp. day.
3) No visible smoke or leaks of oil...but its going somewhere (!).Now the dry sump system is hooked up to the S/C's oiling system...so maybedo I have to account for this? ..And why?
Any knowledgeable comments would be appreciated.
Regards

2) Don't have a definitive answer for #2 without further investigation but see #4
3) Your dry sump engine does not share oiling with the Edelbrock oiling system. The E-Force has a sealed gear case with a 100,000 service interval.
4) Likely you are pumping oil through the intake via the dry sump vent. Pop loose the air bridge and see if it and the throttle body are soaked with oil. If so, you may want to consult with Edelbrock directly via their tech support. The solution may be as simple as running a lower level in the engine oil reservoir.

Motorhead47...Re a Dewitts radiator installation...have a friend who installed one after a twin Turbo installation. He didn't like it for his application...claimed it blocked incoming airflow. Went back to stokf LS-7 radiatorand bigger cooling fans, I believe.
However, is it his a good addition for me wth an E-Force S/C? I assume you did one on your car and liked the results. Is that correct?
Thanks,
Duffy

Ken, so let me get this right. By adding oil I'm making it worse, is that correct? BTW I cracked open airbridge and checked throttle body.... it was dry...so maybe what R.D. Wooden wrote...that I need additional ventilaion is more applicable.Anyway, I'm calling Edelbrock Tech Support later today. Probably not the first time they've been asked this question (re increased apparent oil usage)
Ken do you have a contact at Edelbrock in Torrance CA?
Thanks,

My car has a Dewitts radiator, twice the core size of the stocker. The combo of more capable radiator, 160 thermostat and cooling fan adjust keeps me well below 210...usually in the 180-190 range.
You could probably accomplish the same effect with a dual fan setup. You'll end up spending about the same $$$ for either a better radiator or a dual fan setup. The radiator is a direct drop-in, not sure about the dual fan setup.

I was wrong with my initial assessment that there was no oil in the throttle body.When I looked past the butterfly valve and I wiped lightly with a paper towel, it was soaked with oil (as aresult of increased pressure from the E-Force S/C installation).
This also explains detonation I'm experiencing after low rpm use...cylinder head and valves probably getting carbonized and when the "coke" gets very hot it probably causes preignition...despite all the octane boost I'm adding.
My conclusion, which Craig (Polo1) recommended was to get a catch can installed, which as I understand it, would re-route the oil into a small holding "vesel" rather than letting it go into the intake.
Did you, or any of the other folks who may reading this post, install a catch can and if so, what was the source?
Thanks for yourassistance,

The good news is it looks like we found where your oil is going....a common issue with LS2/3/7 engines. You might want to wander over to the Z06 forum and do a search on oil consumption and/or catch cans and see how your car compares to other Z06 engines. A good friend tells me his 2007 N/A Z06 always seemed to have oil in the intake.
A quart every 1,500 miles seems like a lot to me. Are you running the base supercharger pulley that came with the kit?

Thanks to you, Craig and others, I'm doing the following:
1) Going to a higher viscosity motor oil. Currently have used Amsoil 0W-30 Signature Series synthetic since new. Changing to Amsoil 5W-40 "European Blend" recommended for turbo and S/C applications.
2) To cool better...going to have a Dewitts 12" dual fan kit installed.
3) Last and probably most important, getting an Elite or equivalent oil catch can installed so that any "sucked-in" oil will not end up in the intake and potentially fouling my valves and cylinder heads...and adding to detonation issues.

I really appreciate the knowledeable advice and sharing of experience you guys have given me. While I'm not new to high performance vehicles. I am new to S/C applications.
Thanks and Best Regards,

hose coming from the throttle body.To the intake manifold. Maybe you have one too and it's backwards pressurizing your crankcase? Thats way too much
oil.My two F/I builds used none!
