Just raced an auto 4 door 2004 cavalier from a 20 roll and it really showed me how poor my car is running. As soon as we went I jumped him by atleast a car length and very very slowly pulled away. I did win, but damn, only by like 2 lengths. Once we got that far he wasn't catching up and I wasn't pulling away, just stayed even. What do the 4 doors run, I figure they're good for low 16's but that's not saying much for a 350 tbi at all.

btw setup is pretty much an l98 with tbi instead of tpi. No headers, just catback with no cats. Also have an open element, motorvation chip, and bosch plugs and wires

 

My step sister has one, I love it, especially if you put the auto into 1st and power shift it.

I was extremley impressed when I first drove it.. those little suckers have some pep to them.

Of course.. my car is much faster, but still its pretty peppy for a 4 cylinder.

 

Your chip is killing you. Your car has much more to offer and it needs more chip work. An off the shelf chip will not suffice and to get it right you will have to burn one yourself or take it to a place that can dyno tune TBI vehciles. If your motor is basically like an L98 your car should run low 14's and be far faster than it is now.

However, my old cavy coupe with the 2.2 Ecotec was just as fast as any stock LO3 or LG4.

 

my bone stock 05' Sunfire 5speed ran a 15.8 at 88mph with a dismal 2.4 60ft. with a better launch it would easily be a low 15 sec car

ecotecs are pretty decent as far as 4bangers go. they really wake up when boosted. i kinda wish i could turbo the thing and see how fast it can go, but i just bought a house and cant afford the new car payment anymore

 

I've got a friend who went 15.3 with nothing more than a muffler and a CAI so I know they're not slow. But it was the 5 speed coupe.

btw, I can't remember for sure but do you have to have a laptop to do your own burning or can in done on any computer?

 

It is best to use a laptop so that you can have instant results right in the car. You will also need it to data log.

 

Um, yeah....you powershift a stick, not an automatic.

 

Frig Rod Millan ( big chevy road racer and stuff) Made that cavalier in the street tuner challenge. The thing was beating turbo'd Skylines around the track with only 240ish HP . SMOKEING supercharged K swap hondas/acura's . I was impressed. Even the guys on that NOPI show are bragging the new ecotec up.

I have also seen a 5 speed coupe run low 15s all night long.

 

that's what I figured.

btw, I just can't see a chip swap dropping me a full sec..if not more.

 

no chip swap from off the shelf is gonna give you a second in the 1/4 . Noway no how.

 

I can think of one.

Pull out the 55 lb/hr 305 injectors, 305 Prom, 305 Knock Sensor and put in the equivalent ones from a 9C1 Caprice. That will really wake up a stockish 350 swap into F-car.

With my 1991 G20 Van, I squeezed 3 tenths in the 1/8 consistantly out of my Custom chip vs. a stock chip on a stock 350 TBI. It was slower to 60' on the Custom chip than the stock chip, nice wheelspin off the line.

 

Your right...it could be more than two seconds. I am dead serious. An LT1 cam alone in a stock LO3 (or any stock TBI motor) will make less power than stock on a stock tune. A 350 motor with 300+hp potential running on a tune for a 305 with 170hp is being horribly restricted from its potential. VE, fuel, spark, injector control, etc etc are not optimized for your set-up and are destroying your fuel economy, throttle response, part throttle power, WOT power and overall drivability. The first time you burn your own chips you will be floored at the difference it will make. About 30 burns later and your car could literally have over 50+ more hp. Refer to these threads for more facts and detail on combo's similar to yours.

Don't like to tune, tough!

Budget TBI buildup - look at the tuning that is necessary to dial in a new combo.

 

Well I've got a 350 tbi chip for a caprice by motervation so it's not 305 tune.

 

Ecotec.
