Well,I never race anything from a stop or roll while my car is in overdrive. You can put it in drive and just stomp on the gas or shift it yourself if you want afew more rpms, but at the top end you won't get anymore power for the few rpms you gain.

Laters,
Conrad

You are way out of tune. My 4500lb vortec V6 truck would beat a first gen neon. You have major problems.

I had a first gen neon as a DD, and well, I have beat a vortec v6 in a silverado, no lie. I also had an auto.

My buddy has a nice little neon though, Itll give a 350 TPI a good run, NA. Its quick.

sorry to hear ya lost.

No you need to mash your gas. You are extremely out of tune. Either your carb is out of tune, you have your timing wrong, or you have a bad AF ratio going. I do not know much about dialing in LG4 cars so I can't offer much more. But a full exhaust and cammed LG4 should make way over 200hp and 300 lb ft. There could be a lot of things wrong with your set-up.. A bolt on first gen neon is no match for a 350 TPI by the way. Not even in the same league.

I used to have an Lg4, and boy, I would be very suprised if that thing would beat a Neon on on 3 cylinders. I have a friend with a pretty quick 1st gen Neon, single cam too. He's only got bolt ons and he has taken out TPI 305s without a problem, he can easily run with my buddies 89 GTA L98. Its close, but I wouldn't say that a Neon can't be in the same class. Oh yeah, its a Cavalier Z24 by the way I have a 98 for my winter beater, very very slow

10 may be a bit high. I would start at 4 and work my way up. Most cammed 305's like between 6 and 10. There are lots of varying factors but it is a starting point. Someone who knows how to dial in a LG4 is gonna have to chime in. If was an LO3 I would be all over it. I don't understand the computer controlled carbs at all.

Do you have any track times? With your mods you should be at mid to high 14's all day long. No way is a bolt on neon even going to be close to that. The SRT4's are a different story. But your average run of the mill neon will run 16's.

What does this neon have. It would have to have serious mods to even hang with a cammed 305. You do realize that a stock LT1 can still beat a stock SRT4 neon. Sure it is close but that is a turbo car that puts 220 to the wheels. A first gen neon with bolts ons is no where even near the numbers of the new SRT. My buddy drives one and so does my cousin. Both are mid 90 cars or so or whenever they first came out. They have like 100 hp and are horrendously slow. A cat back and cold air kit will only make them super slow instead of my previous rating. THere is somthing wrong with his car and he needs some LG4 experts to help him dial it in.

Your convertor is not locking up do to the fact that you put on a after market carb that may hurt you a little.

I would say take it to a local shop and have them tune up your car and replace plug and wires.

Get your gauges fixed and and shift it around 4200-4500 RPMs you can feel when its stop going through the peak.
