Just got a My Dyno Chart
With these mods: 2001 LS1 stock Engine,(78,000 Miles Now) Auto Tranny, All stock without K&N filter, B&B Bullets.
(I have a engine oil consumption problem only with high rpm(above 3500 RPM driving.)however there is no oil in my catch can.
I will going to replace valve guide(stem seal 8EA).
Is this good choice for a oil Consumption?
Also, I have a one more problem with spread black tar(soot) on rear butt after high rpm driving. anybody know about this thing happen.
Do these numbers looks normal for my car miliage?
Do you see any problems with, or indicated by, this chart?
I wonder HP&Torque Number is too low than Stock Spec Number.
I found below numbers on New 2001 Corvette.
Max HP:350/5200RPM
Max TQ:49.8Kg(4000RPM),47Kg(2500RPM),44.2Kg( 1400RPM),41.5kg(1000RPM)
Thanks for your time!

The factory rating of 350 hp is measured at the engines crankshaft... The dyno you are on measures horsepower at the rear wheels... There will be a 12-18% horsepower loss from the engine to the rear wheels via suspension and transmission.. Its called driveline loss.. Auto transmissions have more drive line loss than manual transmissions and independent suspension cars have more driveline loss than solid rear axle cars.. 288rwhp equates to 350 crankshaft hp with your automatic transmission.. Your numbers are perfectly normal

YES this is totally in line --with an A4 i find the correct deduct for RWHP is -22%---so if you take the stock 350 crank HP and subtract 22% you get 273 RWHP----If you add about 8 RWHP for the exhaust and 8 RWHP for the CAI that puts you right on your 289---Don't get caught up in all the adverised HP gains of mods--Realistically i always only see about 8 for any catback and 8 for any CAI---
