im trying to find some information a little more ls1 specific... all i could really find was sbc stuff

but what im wondering is can i run a single plane(victor jr. efi setup) with a 90+mm throttle body on the street. my car is a heads/cam m6 and it is daily driven and mostly raced on the street and rarely at the track, so as far as performance goes in generally am looking for a little more top end power. i am still on stock bottom end though so i cant really spin the rpms all that high liek 6500-6700. so is it worth it to go single plane?

any advice would be greatly appreciated...oh yes and eventually this would be converted to a direct port setup, which is why i was leaning this way in the first place. thanks for the help.

 

yes u can drive it daily with that but look at professional products intake its aluminum but it gives more power up top and they come in a 90mm form so that would be perfect for your setup
u want be turning enough for a vic jr

AND U POSTED IN THE WRONG SECTION BUT THANX FOR SEARCHING

 

i actually have a ported professional products intake now... im just trying to squeeze every bit of horsepower that i can out. thanks for hte help though

 

A FAST 90mm would be a better route IMO.

Single plane manifolds are typically used when forced induction is a factor on the LSx based motors.

I think there is a thread around here where a Victor Jr. produces less power on an N/A setup.
