how to get more speed

Is there anything that i can do to my 92 sc2 to make it go past 115 cause I have looked at everything and it doesnt look like there is anything i can mess with to get it going fast. I shortened up the air intake and i replaced the stock filter with a k&n filter and I now have a glasspack exhaust on it which helps a little but i still cant seem to figure anything out on it!

Thanks

adding all those things isnt going to turn a saturn into a porche

I have no trouble getting mine to 145 (km/hr)
I don't recomment it (see above post)

Did you notice the other post by kingery08?
A severe vibration was caused by the tires being down to the wear bars!

i just got the car like a month ago and the owner before me had not gotten new tires in a while and i just now had the oportunity to get new ones :loser:

did i say i wanted it to be a porsche? Nooo

If you want speed, buy a fast car. Saturns are not fast cars. I think even the ION is speed governed around 115. Sporty... yes, fast... no.

Try a Firebird or a GTO.

I had an old car with a 1500 cc engine. To make it go fast I had to find a LONG STEEP hill. Worked every time.

ill have to go lookin for some then lol:iceslolan

you are asking your saturn to be a porsche if you want it to go past 115 and it isn't. it wasn't designed to go that fast. anyway, switching the manual pcm to an auto pcm will get rid of the speed limiter. I have heard people hitting excess of 130 doing this but i don't know if it applies to earlier saturns plus there are some side effects to it too. Isn't 105 or whatever your limiter is at enough? I like hitting the high speed too and have done it a few times when i first bought my saturn but quickly got over it. Quickly punching it to 65 in a 45 is good enough for me. Also, i would advise you have proper components and make sure your car is in top condition if you insist on going that fast (wheels aligned, springs/struts, sway bar, etc.) just cuz it's somewhat safer for you and your car. buying a nitrous kit or building a turbo will get you there a LOT quicker than every single bolt-on that exists for your car are on there.

auto pcm on a stick? cool. what are the side effects? I'm about to replace my PCM but getting one for an auto is cheaper. I have a 5 speed.

I cannot remember what needs to be done or what to make it work. You should ask the good folks on www.saturnfans.com. They will know. They may laugh at what your goal is though.

the saturn sc is indeed a S port C oup. i believe we can have fun while we drive and thats the resone we test drive before we purchase. now now we might not all have daddy to get us that porche or viper but last i checked super street mag. a nissan with 4 little donkeys doing about 850HP uummm not porche nissan 2.0L the old porche carreras S uper C harged also 4 ponys i believe not sure 2.4L well the one i drove had an aftermarket oversized supercharger 1 2 60 in 1st gear....just to say i feed my saturn what it likes and to add as a production car i believe 2nd lightest next to the lotus elise 2005 just under 1900Lbs. the saturn sc2 i believe fully loaded 2400Lbs. so what you feed yor saturn and how much performance and i just like to add fun is limeted only by your state and local laws. drive safly on commercial streets.

ok there is practically nothing to make it faster. the one that can allow to go the highest is the sc2 which is limited to 124mph. there is a speed governor that is programmed into the pcm so you cant travel over the set speed. you have to reprogram the pcm to allow it to go faster.

true true true that, you also dont want to destroy your engine at 8000 rpm. thats the reson for the programing. ladies and gentleman yes we can go faster just watch out for the popo and the family in the minivan. remember drive safly.

like that little text doc. on my last submit. that ladies and gentleman is the sheet that holds all the math in performing this affair yes even at 8000 rpm. just feed properly and tummytuck in the areas needed.

dang i meant blueprint.......

double dang yes you will have to reprogram everything from advance to when the fan should come on i dont see how allthe hardware can work without the software at peak performance. i guess being exact is important with all the sensors, switches, and fuel injection. i believe pocket programmer or jet can do this very bad thing to your saturn or any car/truck. just remmeber a stock engine with the average bolt on can end up advancing all the way to a pile of @#$@ when messing with this safty margine. just for the people who drive 60 or 70mph. take a look at your rpm gauge. go ahead just a little faster wow that rpm gauge is going up with my speed. now see the red line do you really want to go to that place.....scary....not without assurance that everything will keep up...cars are like people prepare them well for the task in wich they are about to take and hope nothing screws them up...

hay saturiens by very proud. saturn held the fastest in its class at the salts untill the cobalt by chevy took the record. i believe saturn just recaptured it. i cant remember the speed ~187.mph last one ~205.mph
if not exactly that darn close to those numbers as i remember. if anybody has this fact in front of them take all the glory...in presenting to all our brothers and sisters the exact speeds.

well with a saturn, you never reach the redline before the governor shuts it down. redline in a dohc saturn is 6500 rpms. cant remember what sohc is. but i can take mine up to 108 before its stopped, from there i still have around 1500-2000 rpms that still could used. someone had figured up the gear ratio and found that a saturn with a mp3 transmission can do 145mph, cant quite remember if thats right might be a bit higher, at 6500 rpms without the speed governor.

i say if you want a faster car then buy one

i would say close enough to the numbers. the statement about just get a faster car i will agree with you. the firebird trans am is a fav. there was a guy selling one in my area with twin turbos. can you amagine that on a park your car and sell it lot. you know the car didnt come like that he was sure selling it like that. one day on the lot and poof gone. it sounded like death was coming when you heard that engine scream roar hell scare the hell out of you. very ballzy. 3000gt vr4 very nice 2. you can really make them move. my thing right now besides just raw power is hp 2 wieght ratieo.
i forgot the formula something multiplied by what zoomzoom.... any way the thing is 175hp ~ 2200lbs. = ........ ~ 3800lbs if you know what im putting down is true you also know cornering, brakeing, and all out feel of the car is different. a good example of that is the lotus elise in at 1900lbs with the same engine as a toyota celica with just a few tweeks to the engine and programing. if you read the performance ratings on braking ect...ect...of both cars together you cant imagine they are using the same engine. i belive the celica comes in fully loaded at about 2800 or 2900lbs. fun is the over all thing. getting in your car and enjoying your drive to work. and be the owner of your life size modle car. beats building bird house. dont get me wrong i like birds.

i like the lotus elise, except for the fact of the pile of junk celica engine. that is the downfall of the elise. ok but now for a saturn, no on really knows the potential here. its not like hondas or mitsus or anything like that. the closest thing i could compare it to is a nissan sr20det, power wise is not the same but the strength i believe is. the block is great, no need to replace, upgrade to some forged pistons and rods and thats basically it. the crank is nitrided. the transmission is another thing, no need to beef up here. the gears are constantly meshed and the only thing that needs some attention is the differential pin. these transmission have shown to break dana axles on rockcrawlers with no ill effects on the gears.

everyone may laugh at the fact of the saturn being a potent little thing, but for the same power it makes, modded or not, anything that matches it i would almost bet it would take it. power to weight ratio and gearing. a saturn weighs in at 2390, and there is weight to shed. i have watched a saturn take out a 350z, evo ix, si, and numerous other things. just because a car makes a bunch of horsepower doesnt mean its fast, it still has to make it to the wheels and be turned by the transmission. its also great to have torque, unlike most all imports. you can say yeah i have a turbo or twin turbo and make 500hp, i dont care. i want to know all the figures i could really care less about your horsepower. my car has 116whp and 112 lbs/ft of torque on 155,000 miles, and it can take alot of things on the road. i have burned a 4.0 ranger, slipped passed mercedes e-class, smoke hondas, and a bunch of other cars. i have not come across a guy yet who has a v8 that can pick up better then my car on the highway without his v8 having to downshift, nore any other car. it packs a punch and im not lying, ive driven many cars and because you can smoke a honda doesnt mean you can beat all other 4 cylinders nore because its a 4 cylinder make it unpowerful. im stating facts of many saturn owners and modders. i too will have my saturn boosted and ive already got a new engine for the build up.

have you tried disconnecting your speed sensor. maybe you can rev your engine higher than 6500 rpm and go more than 108 mph speed.

well now i would think it would travel faster then 108 with the speed sensor disconnected but then i wouldnt know how fast i would be going and im not to sure if that would work. it wont keep it from hitting the 6500 rpm redline. but with my project car im just going to reprogram the pcm because im going to have to do it anyways since its going to be boosted pretty damn well.

just like your said ..speed sensor signal is used by the pcm for high-speed fuel cut-off and other things like auto tranny shifting. you will get malfunction indicator light on when your disconnect it but im not sure if it will affect your engine. i need to try that sometime. also i did not know you can reprogam saturn pcm. can you tell more about that?

oh yeah. you can send it off to jet and have it reprogrammed, or if you somehow can get a power programmer to mess with certain parameters. im sort of feeling like doing that but then too i think i much rather jump over to a standalone or some kind of piggyback system like greddy emanage.

don't go to jet. it won't do anything. plus only the pre 96 (or odb II) saturns can be programmed last time i checked. the only things that are worth doing is a wbo/2 and a SAFC to adjust the air/fuel ratio. MSD's rev limiter thing can reset the rev limiter too. Megasquirt is the cheapest stand alone at 500 bucks or so. Disconnecting the VSS while driving is a no-no. although i don't know if this will happen on a saturn, but it happened on my former neighbors 98 suburban. Assuming the VSS goes from the pcm to the tranny, if it's disconnected, the vehicle won't know how fast it's going and won't go at all or the fuel will get cut off or something.

jet can do it to any saturn. and actually does whatever you need done. i might possibly do that and add on a greddy emanage. im thinking about megasquirt but who knows, its whatever works out the best for me.

what do they do that's worth 300 dollars (or whatever they ask for it)? May I add its been proven there's no performance gain? Another thing is you can't remove the saturn pcm which makes things a bit difficult for jet. all it really is is an expensive resistor you can buy from ebay. It isn't this LITERALLY thank goodness but you get the idea.

actually you remove the pcm and send it to jet. they break it open and modify the chip to your needs. they can also remove the speed limiter, like what was the main topic in this, but only if you contact them first. the programming modifys, but is not limited to, a/f, timing, and boost pressures if applied. you fill out a sheet to let them know everything done and whatever else and they modify it.

I'm 95 percent sure that the saturn pcm CANNOT be removed, or at least the newer ones (96 models to current). Another thing, what jet sells for the saturns is a computer upgrade kit and not an actual performance chip. jet products have been dynoed too and they have no performance gain on a saturn. so the way they modify the a/f ratio is worthless since using an SAFC and a wbo/2 on a dyno will give you SOME hp gain in a lot of cases when done properly. Go ahead and get it if you please, but i'm just tryin' to save you money and disappointment.

im not looking for a performance gain from it, but it modify certain items. i have thought about running full standalone system on my car when its time but im still trying to figure out if i want to go that extreme, because i know the race car me and my friend are going to build is probably going to use one so i guess going through tests on that will tell me what i want to do. and price is another thing to consider when i build my everyday car.

but this topic was not about performance gains, it was about the limiters. so thats why i said jet. and the pcm can be removed.

I have a hard time believing that jet can really TRULY get rid of the speed limiter if it can't do all the other stuff it claims to do. a stand alone is the only way to go and that is what i would do if i were in this guy's shoes.
