Rev Limiter on 93's???

[JohnBoy_93Transam]

i got a LT1 trans am 1993 auto. 125,000 miles, and burns a little oil. does my car have a rev limiter? people has been telling me that i will hit that alot with my gear (4.10) but i heared from one of my friends that 93's didn't have them. and i'm not to crazy about trying it unless i know for sure. i have run her to about 6200 before and she didnt' hit it. is it higher?? thanks alot!

I dont know for sure, but Ive always been told, that the Z28's and Trans Ams equipped with Z rated tires did not have a limiter. Im sure something like that shouldnt be too hard to find out.

it has to have a rev limiter from what i know. My buddy had a 93Z and it did have a limiter.

my 93 trans am lt1 has a rev likiter i hit it all the time at like 6400 if you have a chip some of the chips delete or adjust the rev limiter.

i have a 1995 formula LT1, the previous owner got a hypertechpower programer to get rid of the rev limiter and governor, the highest ive thrown it though has been bout 6000 -7000 rpms never went any higher,

I dont think they will go much higher than 6000. These are no Honda's ha ha ha ha.

Just curious... why would any rational person rev what it basically a stock LT1 to 7,000rpm, when it makes peak HP closer to 5,000? If you have that little respect for your engine, get a Honda S2000 and you can rev the piss out of it for a valid purpose

Some of these statements push the limits of believability.

ive gotten it to 6500 rpms, never higher, my honda, 8000 or more all the time ( chiped jdm h22 engine)hahahaahahah,my engine would be screamin in my honda,in my formula it didnt feel right,but i just got the car,was being stupid,and my friend was talkind sh$#%t, and i was racing his 02 stang gt(intake exhaust)i won, but i wont get in to detials cause i know u guys dont like streetracing,but i probaly wont throw the revs that high again unless im gettin smoked real bad or want to blow my engine ahahahahaha (im just so use to throwin revs high cause of my last 2 hondas,bad habit)later dudes

Agreed. Unless you're looking to destroy your motor, there's no reason to hit 6000 rpm, much less over. The red-line for the motor is 5700 rpm and anything over can start to damage it.

Also, addressing what was said before Fred's post, having Z-rated tires changes the speed limiter, not the rev limiter. And, even then, the speed limiter is still there, as you'll find if you search these boards.

The stock LT1 programming has a rev limiter of 5,800-5,900rpm, depending on the trans type and which gear its in. The cars without the Z-rated tires have a speed limiter in the 108-117MPH range, depending on the year. The Z-rated tire versions have "255" in the speed limiter field, the upper limit of an 8-bit binary field.

I am waiving the BS flag..................

You cannot elimiate the rev limiter. All you can do with a Hypertech is raise the limit to a slightly higher number. I believe that the highest threshold from hypertech is 6200 rpms. If the tach reads higher, it's tachometer error and not reality.

[ConElite]

Thats what I was thinKing Joe. I have not really heard of anyone NOT having a Rev Limiter. The Speed limiter ok, but not the RPM limiter. Either way, with a 5.7 I dont think you need much more than 6k. Unless your Top Fuel, 9000RPM

joe 1320 glad ur doing better,glad to see u on the forum,sorry bout what happened , god bless,ive only done it once,could have been 6200-6400 ,freind in the car told me 6500 i was paying more attention to the road then the tach,i didnt set up the hypertech myself, but in the instructions it says u can elimnate the rev limiter, im not lying, i have no reason too(it was in 2nd gear)later

When we would Load the Pre-settings on my brothers 96 Z, it would allow us to Raise the rev limiter and eliminate (well raise to 255mph) the Speed limiter. I higly doubt that it was 6500 although Im sure the engine can do it. The bad thing about that is at those speeds your going to be getting some pretty bad Valve floating going on with Stock Valve springs. Hello bent valves and damaged pistons.

i know, and i will problay wont do it agian , but i know it was over 6000 when i did it,i know in hondas its okay,but my dad told me its no good in v8s,i just coulnt lose to the stang,it was very stupid i know, later(ps going to the track in 2weeks)probaly wont race though dont want to break anything,
