If you can, post up what numbers you have gotten out of your setups, and what you have built.

I am Dynoing here soon..I'm wondering what you guys have so I can compare it to mine for a rough idea..:drive:

505/475 at the wheels.

402ci LS2 11:1 compression
STG 3 Livernois L92s
stock L76 intake
240/252 .650/.661 114+3 cam
1 3/4 jet hot headers
stock LS1 MAF

should make more once i go with bigger headers, go speed density, put an underdrive pulley on, and hopefully ill have another option for intake manifold

i'm new to tuneing but how to just going over to speed density help you pick up more power, cause when i take mine to get tunded, and converting isn't hard i'd prolly do the same

because the maf is only 78mm in diameter, and is a decent restriction when your flowing that much air. just take off the maf and put a coupler straight from your lid to your throttle body. should pick up a decent amount for a bigger cubed motor IMO. tuner will just tune in speed density mode.

if your maf isnt pluged in or doesnt work, your car goes into speed density mode

Speed Density won't net you more peak RWHP than a properly tuned closed loop engine. It can improve drivability with larger cams.

cool thats the idea i was thinking it helped. i have truck/vette maf its alot bigger then the stock one so i dont think its a restriction at all anymore

thanks for the help

why not when your going from a 78mm opening with some restriction, to a free flowing 90mm opening.

thats like saying a stock throttle body will make just as much power as a 90mm
