So I have a 1991 Firebird w/ the 3.1(auto)
whats the bone stock quarter mile time?

now - whats the (theoretical) quarter mile without spare/jack, rear seats, washer fluid reserve, 2 floor mats.

ya see, im dropping in an LS1 with an LT1 chip in future, so bear with my "weight loss" question plz.

 

i am 99.9% sure a LT1 PROM will not work with an LS1

back to the drawing board, buddy

 

good answer on the 1/4 mile question

but i think anwhere betwen 16-17

 

I figured b/w 16 and 17...
So answer this maybe -

My car has AC Rapidfire plugs, sensatrac shocks and struts, cold air intake w/ open element k&n, a gutted cat, no backseats, no spare/jack.

I am hoping for too much if i guessed 16.2?

p.s. I might be being vague on the chip but its a chipped LS1 - know that. I know cause Ive ridden in the car with the engine i am buying... sounds mean and im sure its gonne haul my car cause its hauling the suburban its in right now =)

 

Take it too the track. Guessing 1/4 mile times never works.
Everything plays a factor, Air temp, milage on car, weight of occupant.

I will guess for you. I would say 16.5-16.8.

I am not trying to be rude. I am just saying if you want to know your 1/4 mile time go out and race it. This will you give you the time, and not the time we make up for you.

 

i now for a fact what it will run friend of mine has a 91 RS 3.1 Auto bone stock 17.20s all day long so you figure with a little bit of help you will have a 16 second car

 

G-teched my beast and it pulled a 17.8

Im so proud. Whats better is that i get 12.5 mpg around town! wooha

 

Sounds like you could use a good ole' tune-up !
And maybe get your injectors cleaned .

 

Track yes... i plan to. Just seeing if anyone had a good idea.
Im tryiong to make the car a flat 16 with almost no investment to tide me over til i drop in the LS1 - So im also looking to bump up the fuel pressure (anyone know the magic number? im thinking around 50), and maybe throw in a decent mod like a cam for not a lot of money.

 

heh.. needs more than a tuneup. Lifters are tapping like a sumbitch, need to replace them along with the cam. Just fixed a coolant leak(leaked a tank a week) that turned out to be the water pump gasket. We got some spark plugs for it... maybe that will make a difference. Hate this 2.8l with a passion

 

hey hey my post 67cam88 - jk hehe

You wont hate it so bad once you get it running good , I promice , its not that bad .
I was checking out your website yesterday , WOW , I like the nice , new fresh paint job ! Your Dad did a pretty good job !

 

Make no mistake, the sensatracs dont hold a candle to KYB's or anything that pricey... but yes they are a nice mixture of performance and ride.
