What compression for sts
Just bought an sts kit with a gt67, methonal injection, no intercooler but I plan to add one...
Im in the process of trying to figure out what compression to run. I know that lower is better because I can get higher hp with 93 octane.
I have been trying to figure out the compressor map for a 347 block.
My big problem is I dont want to go too low of compression because I dont want to change turbo's.. It seems if I go lower compression it will have to work the turbo harder to get my hp which will be bad for my smaller turbo
I have been thinking about 9.5:1 or maybe 9.1:1 compression... does this sound about right?
My goal is 600-650 rwhp.. Maybe not even that much..

IMHO I would go somewhere close to your 9.1 with your goals. Get that FMIC too...

lol... I meant the gt67 compressor map in reference to a 347 block... What do you guys shift at?

Holy ****! 5200 I can see Im going to have problems alreay. My vig 3500 is too big.
Do front mounts run up to higher rpms? Maybe thats why I see lower ets with higher hp with the sts kit
With nitrous I could run 10's with 500hp.. With the sts kit it looks like It takes 600+ for low 11's
Im thinking about adding a small shot to my kit.
