why is your oil pressure so low compared to other ls1's? The camaro I had was almost 3/4 on the gage when I started it

[brian1570]

@alexelcui yeah it'll make 55-ish psi on COLD START. this was a warm start and normal idle pressure is 39-40 lbs. trust there is nothing wrong with my oil pressure, the car has a melling pump that is very stout.

[tmakidd0703]

dont you lose power at lower RPMs becuz there is no back pressure????

[brian1570]

@tmakidd0703 no. it's pretty widely known that "back pressure" is an old wives tale. there is no such thing as back pressure, it's a term people use to explain what they don't understand. exhaust gas velocity is what determines torque curve. smaller diameter pipe/smaller internal volume = higher gas velocity. at low rpm's this helps torque but at high rpm it hurts hp. my system has 1 3/4" primary headers, so i still get velocity, and at high rpms i have little restriction.

nice.

needs moar revs though. WOT video soon?

[brian1570]

yeah should be up tomorrow with some better vids. i took this one at my house and ive already had multiple noise complaints and cops knockin on my door so i thought ide keep it under 3k lol.

[RPMproductions1320]

@parkairfreerunning it had an x-pipe prior to this. got a ticket so i had to quiet it down some. go look at my older vids.

[parkairfreerunning]

Bro, please please please put an x pipe on. That beast would sound insane!!

[EVILWS666]

Brian, if I didn't see what car it was I would think it was my old WS6

[alexelcui]

hmm not bad at all my bad. By the way very nice and clean camaro ;-)

how did you get your check engine light off if there is no o2 sensors

@brian1570 ok cool i was taught tht about back pressure in my auto class so thnks for clearing tht up
