3.4l Looking for 13's

[12secondv6]

I would expect the 60 ft to be quicker witht he converter/ gear you run.

What was you launch rpm, tire psi etc?

[quicksix956]

I don't know tire pressure what should I run it at? I launch right around 3grand more like 2800 though.

[quicksix956]

If I got an auto trans should I put in in drive or manually shift it?

[Tru2Chevy]

Leave the trans in drive.

What tires do you run at the track? Brand/size?

nitto drag radicals 245/60/16 I think for the tires

[12secondv6]

You think?

Check the tires and let us know.

Nitto makes a 245 50 16 extreme drag radial.

Tire psi is CRUCIAL for good traction.

I liked as low as 20-21 psi... but it can vary from car to car

[njspder]

stage is also very important. are you taking time to put it in the beams the same way.
dont' just bang it in, take your time and stage shallow. first get your stage and launch consistant, then you will see what you are working with.
gear selection has nothing to do with v6 or not. it has to do with the power band you are using. ideal gear selection comes from running the engine through the entire power band in every gear you use at the track.

After lookin at your slips I can see that you are definetly losing traction down track, past the 330' mark. A very good tire to run is the Hoosier Quick Time Pro tire. Be sure you use one with as much side wall as possible.

thats pretty hard to believe

however there is something wrong .. what type of cam do you have in it? perhaps a cam without a cam position sensor tab? that could cause it to run pretty bad (ive seen it 1st hand)

my 3.4L with some boltons ran a 10.066 @ 69.xx with similar 60's

WAY overkill.

Simple drag radial for sub 2.0's
BF drag or nitto's

[theman3.4]

It really isnt overkill at all. I have been drav racing since I was 8 years old, 11 years now, and as much as you think it cant happen with a street car, you are losing traction beyond 330'.

I have an 82 s10 with the 3.4 crate engine, headers, 2 1/2 dual exhaust, MSD Ignition, E Fan, 4:11 gear. Last time I ran 1/4 mile i ran a 16.00. I have been 1/8 mile racing at school and recently started using the Hoosier Quick Time Pro tires. I did not notice any difference in 60' or 330' times because my tire is 1'' taller than stock due to my combination and gear. But my incremental time between the 330' and 1/8 mile picked up 2 tenths. That is a very considerable change.

I will have more information monday after i race this weekend. I am trying different tire pressures and I will be racing 1/4 mile on sunday.

Hopefully getting a naturally aspirated stock 3.4 with a carb into the 15.50's in nearly stock form.

[StudlyCamaro]

i'll believe that he is loosing traction after 330' when i see a video of it... an automatic 3.4L is not going to randomly loose traction after the 330 mark unless it hits a patch of oil or water... and i certainly hope that that is not the case at a drag strip

you claim that your car gained .2 in the 1/8th without gaining any in the 60' or the 330' on a 1 inch taller tire... that makes sense, not because you were loosing traction before. you might not have gained in the 60 or the 330 because although the tire hooked better it was larger and took more power to get it to start turning, once it got spinning though it was 1" taller and the car will be propelled farther per revolution of the wheel... not because you didnt have traction past the 330 mark

[theman3.4]

Think what you want, I have more years of experience in this field.

A 160 hp engine in a 3000 lb car will black track at almost half track. The only solution to this is a sticky tire.

[Tru2Chevy]

That would have to be one of the worst prepped tracks in history.

Show us some proof of a 160hp, 3000lb, automatic trans car loosing traction at the 1/8th mile, and we'll all shut up. There are lots of people here who have been racing longer than 11 years, so don't think that makes you special.

I don't mean to sound like a d*ck, but you are using quite a cocky attitude for a new guy that no one knows....

[njspder]

this thread is reaking of BS. spinning the tires suddenly at the 330's is a bunch of crap.
i have been around racing for almost as long as you have been alive, and i can only think of a handful of cars that break the tires that late in the track. they are called funny cars and top fuel dragsters. maybe in your infinate racing experience you have seen them on tv. jackass.
