Question about TorqueSRT-Wannabe 07-18-2006, 07:49 AM anyone know of ways to increase torque? are there performance applications to raise your torque numbers? neon_rt 07-18-2006, 11:14 AM Cold Air intake and cat back exhaust will increase torque some (maybe 10ft lbs total). If you want to really increase torque you need a turbo charger, NOS or bigger engine. SRT-Wannabe 07-18-2006, 03:29 PM oh ok, thanks. SRT-Wannabe 07-18-2006, 10:42 PM what is the stock compression ratio of a 2000 dodge neon es? what measures can be taken to increase it, what is the safest increase on stock motor? I have plans to get mangaflow exhaust, performance headers though i don't know who makes headers for neons, CAI, what tuning can you do with these applications? just looking for some info to do this right. HPNOTIQracing 07-19-2006, 08:14 AM your asking the wrong questions. if you talkin about raising compression you need to deck the head which calls for removing the head and sending it to a shop. and or raising the compression of the pistons. now the question is what are you looking for as far as 1/4 times or hp numbers but the hp # doesnt really have to do with what im asking SRT-Wannabe 07-19-2006, 06:12 PM your asking the wrong questions. if you talkin about raising compression you need to deck the head which calls for removing the head and sending it to a shop. and or raising the compression of the pistons. now the question is what are you looking for as far as 1/4 times or hp numbers but the hp # doesnt really have to do with what im asking what are the compression of the pistons? HPNOTIQracing 07-19-2006, 07:21 PM im not sure i will find out. im pretty sure they are the same as the first gens. sohc 9.6-1 dohc 9.8-1 i think SRT-Wannabe 07-19-2006, 07:40 PM what would be a safe increase, and how would it affect the performance of the car? skatendestroy 07-20-2006, 12:32 AM You could also get a udp to free up power also mabe go to a smaller rims size when/if you decide to get new rims. SRT-Wannabe 07-20-2006, 07:19 AM what is a upd? personally i think 15s are small enough, i'm just getting different rims so the six piston brake pads can fit, or maybe something else, i'm indecisive on the brake kit right now. skatendestroy 07-20-2006, 08:53 AM udp=underdrove pulley it doesnt make any extra power but it frees up power that would be used to drive the alternator and accesories neon_rt 07-20-2006, 11:45 AM For every pound you add to the rotating mass (wheels, tires, brakes) you will lose performance as if you added 4 pounds of weight. If you put 17" wheels on and a big brake kit (extra 20 pounds per wheel x 4 wheels x4 for rotating mass = 360 lbs) you will be sorry. You will need 17hp more out of your engine to make up for the rotating mass. Wollf 07-20-2006, 01:18 PM Interesting theory, i have never seen that before ... but the calipers dont rotate... having stronger brakes is more wieght true but its no diff then throwing a heavy backpack in the back seat.

SRT-Wannabe 07-20-2006, 01:46 PM udp=underdrove pulley it doesnt make any extra power but it frees up power that would be used to drive the alternator and accesories how much udps go for? who makes them? neon_rt 07-20-2006, 02:50 PM The Sohc is the one with 9.8:1 compression The Dohc has 9.6:1 The compression ratio for the SOHC was reduced to 9.3:1 sometime after 2000 except for the Magnum which remained 9.8:1, I don't know which year exactly. Usually if you are putting on large calipers, you would be changing your rotors to larger, heavier rotors. The brake kits I've seen have both pieces. From what I've seen, the best course of action with Neon brakes is to get sloted rotors and street/racing pads. That adds no extra weight but gives 20-30% better braking. The key to neon performance is to keep the car and rotating mass as light as possible. The engine isn't overly powerful and bolt-ons only give small incremental increases. I would save the $ for a Turbo. If you add a whole bunch of bolt-ons, you will be taking them off to put the turbo on and money will be wasted. Some suspension experts agree that the best size wheel for the non-turbo Neons is the 15x7. This provides the best balance between handling and acceleration/braking. SRT's are a different story since they have power to spare and need a lot bigger brakes/wheels to handle the power. SRT-Wannabe 07-20-2006, 05:19 PM do you know why they have been increased? if i am going to get a turbo, i need a list of internals i need to upgrade, i'm getting a turbo in the future, i know a few interals to upgrade, but i don't know all. neon_rt 07-20-2006, 07:09 PM What increased? (they?) SRT-Wannabe 07-20-2006, 08:07 PM lol i meant why was the compression decreased. sorry :lol: neon_rt 07-21-2006, 01:20 PM The compression was reduced b/c of stricter emission requirements. I think it was 2003 when the change was made, I don't know for sure. People that want to add a turbo specifically look for the 9.3:1 engines b/c the reduced compression ratio allows more boost without changing the pistons. I've heard that 6psi is about as much as you can go with a 9.8:1 comp, with the 9.3 you can do about 9psi. With turbo pistons (8.2-8.8) and better rods you can push 14psi or more. A built up SOHC engine can reach about 400hp if you have the $$. SRT-Wannabe 07-21-2006, 01:33 PM The compression was reduced b/c of stricter emission requirements.

It was street legal in all 50 states, made 4 more hp. I think that it is the same part that is on the 2.0 Magnum (neon R/T and ACR 2001-). SRT-Wannabe 07-21-2006, 05:58 PM thx for the help, this info has really been alot of help, now i just gotta make the money for the parts :lol: neon_rt 07-21-2006, 07:57 PM If you get an AFX controller (premium fuel only) you can switch the head you have for a Magnum Head. If you find one in a junk yard, get the head and header (with cat). The Magnum head doesn't have provision for the EGR is why I mention the AFX controller. The factory controller will throw the CEL on b/c of the EGR not being hooked up. The AFX will ignore it. The Magnum head will work better with a turbo setup if you should decide to go that way. The AFX and head/header should be good for 12-15hp. maykelcj 08-06-2006, 02:18 AM how much udps go for? who makes them? www.modernperformance.com your one stop for neon's stuff. FemaleRacer 08-06-2006, 02:51 AM Are you planning on track racing this car? I only ask because you can just invest in a second set of racing tires (or for the time being use your origionals. I know that's what I do sometimes with my Neon. It's really not hard to change the tires at the track. Trust me--after my first season I think I could do it in my sleep-lol. And you get to have the sweet rims/tires for off the track. (And none of the responsible driver in this forum would ever race illegally off the track ;) )Keep in mind that the tires for larger rims cost me than stock tires of course---and racing regularly at a track is hard on the runbber. It also eleviates having to deal with lowering and then incrasing tire pressures and not needing to bring the huge heavy ass compressure to the track...lol...you get the point. Because they're right on when they tell you that your new tires will effect your cars performance. Just food for thought... SRT-Wannabe 10-09-2006, 12:26 AM what you said just flew past me, I don't get it. sorry :) yale329 10-09-2006, 05:41 AM I did not post such garbage. I have know idea how such crap was posted under my post. Just a dad vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
