Anybody got a ballpark figure on the volumetric efficiency of an 88 L98 with the minor mods listed in my sig? Are there any published statements on the volumetric efficiency of the stock 88 L98?

------------------
-------
88 5.7L GTA
K&N, airfoil, 3" flowmaster, modified MAF

Hotchkiss strut tower brace (bought it second hand but never used for 30 bucks)

 

Usually stock street engines will not have a very high VE - around 85%, at or just above peak torque. But I remember reading a build-up on a TPI 350 which made around 400 hp and its VE was 96% which is good. But an efficeint race engine can easily make over a 100%. Thats cool!

91 B4C 305 TPI - SOON TO BE 383
TREMEC 5-SP, STOCK 1-BOLT REAREAND w/342 GEARS, K&N, AIRFOIL
EDELBROCK HEADERS, DUAL CAT TO HOMEMADE Y-PIPE & 3.5" SINGLE PIPE W/ FLOWMASTER, CRANK PULLEY, MSD, FUEL PRESS REG, COWL HOOD, WELD WHEELS
14.1@ 98MPH
-------------
OTHER RIDE
67 CAMARO - STREET CAR, BIG BLOCK, PUMP GAS
350TH w/ATI 10", 12-BOLT w/373 GEARS
10.94@124.13 ON MOTOR - ET-STREETs w/MUFFLERS

 

stock i believe they were pegged at around 82% supercharged and turbo cars usually go well over the 100 mark
