Wanting to know if i can hit 12 sec in 1/4 mile with 7 lbs of boost, if i cant what what numbers im a looking at and hp?

 

sure y not... also just go to the dyno get it tuned know how much power it actually has then go take it to the drag strip and actually run, viola no more specualtion and wondering...

 

true...but just wanted to see if anyone here with this setup hit 12 sec on a quarter mile.

 

Going to be difficult with only 7psi on that turbo in such a heavy car. Get rid of the VAFC and go with Hondata, Crome, or something of the sort. Have it properly tuned with a wideband by a knowledgable tuner.

 

si w/ gsr ??? why ?

to answer your question NO ! ! !

 

heavier duty clutch
lsd
ditch the vafc for hondata, chrome or uberdata...something other than a vafc
shed some wieght if possible
slicks or dr's
up the boost
dyno tune it.

i could be wrong but i would say youd need something around 280+whp to get consistant 12 second passes. on 7lbs your around...what...240ish? if this was a lighter car it would be different.

 

not with that turbo on 7lbs

 

Try 15psi, that will get you close to the 12's, definately 12's in ef! If you are a good driver, 7psi on a stock b16 will net you around mid-upper 13's.

 

hahaha
ok how about me

can i get it into the 10s ???

lol

 

You just need a bit more boost and you should be in there. I hit a 12.67 with a full weight SI plus a sub and ginormous amp on 12 lbs. Granted my turbo is a bit better but you have more displacement and higher compression.

The only way to really find out though is bolt on a a set of slicks and head to the track. Driver skill will play a big role.

 

even if you up the boost and get a different tuning system you're not going to hit the 12's......your clutch is going to slip and kill all the power you would have gained....upgrade that and maybe get LSD while its apart and you have a good set up
