well i just finished my motor and i was wondering if any one had any opinions on if it would be ok to drive it with out any dyno tuning.
Heres the set up
b16a
.25 os ctr pistons
port-polish
ss valves
titianium ret.
rev valve springs
head milled.4
stock b16 cams
b-m fuel pressure reg. at 50 psi with vacume hose off
p28 with scunk 2 chip
Ive driven the car about 80 miles now and it runs good but i havnt gone over 4.5 rpm yet.And i pulled the spark plugs and there the color of cardboard witch from what i here is good. just wondering what you guys think??

 

bring it to go get tuned asap, the compression is high, don't want it to blow up in your face

 

it will get tuned as soon as i get money.just wondering if it would be ok for the motor.i cant afford it for another month or so.

 

what are you going to used for tuneing

 

i was going to take it to rage performance for some dyno time

 

Has any one on here ever run a similar set up with no dyno tuning?What wer your results???

 

8-( lots of people do get away with doing this ,but dam if you spent so much money to build the thig why even take a chance?all you need is a wideband o2 sensor so you can be sure the A/F is safe till you get to the dyno.

based on your engine mods, you are running WELL over 12:1 compression, and i guarantee your motor is detonating every time you drive it. with those pistons, your compression as around 11.6:1, and with the head milled, it would be over 12:1.

i would seriously recommend not even driving it until you have it tuned.

i had almost the same compression and my motor lasted about a week without tuning, until i destroyed two brand new pistons.
