are high 11s possible?
 

I'm finishing up my new Keith Craft prepped 306 w/ JE SRP flat top pistons. It has TFS track heat heads, TFS street intake, TFS stage 1 cam w/ 1.7 roller rockers (224*/232* duration @ .050, .542"/.563" lift 112* lobe seperation), BBK 1 5/8" long tube headers w/ offroad h-pipe, flowmasters, underdrive pulleys. The car has a t-5 tranny with a motorsport hd clutch, 3:73 gears and a detroit locker. Also the air conditioning and smog pump is removed. No port work is done on the heads or intake. I will be getting the car dyno-tuned at second street speed in perkasie, pa. Are 11s at all possible? If not what do you think the car can run? Also what kind of power will i be making at the wheels. Thanks for your help!

Yeah, if you get a good set of slicks, I think you can break in the 11's. It will be very tough though. I think low-mid 12's might be more accurate.

I agree. Unless your car is really light.

Later,

my thoughts exactly, get the heads and intake ported and will be very close to 11's

I hit a 12.4 with the notch but didn't launch that high and needed to let more air out of the tires. I think 11.90's are coming very very soon and so is a bigger mass air. Good luck and let us know.

oops, forgot to answer you question. Do you have bigger TB and mass air? What size are the injectors? Do you have a computer chip? Be more specific about the app. I think low 12's are in order.

I have only three words for you buddie! YES YOU CAN. Good luck Jason

Right now it has the stock TB but i am planning on getting a 70mm. The mass air is a 75mm Pro-M Bullet calibarated for 24# injectors. I am also going to get a federwell cold air kit. I am planning on putting in the motor tomorrow so i will let you guys know how it goes.

my friend had a similar set up, but he only had a .500 lift cam (class max). he did a 12.3 at 3200ft with the car leaning out. with better air and bigger injectors im sure he can hit mid 11s
