speed limiter?

Just curious what the the speed limiter is set at on a 1990 RS 305 TBI? my speedo does not work and it shuts down, at what speed i do not know, any help would be appreciated.:confused:

My guess with a RS and it did not come with speed rated tires V/Z
the limit should be 115 MPH.

When I had the TBI305 in my '91 RS it would shut down at 115. So yeah, DJP is correct.

Yup, 115 here check this out:

MY 91 TBI CUT'S OUT AT 117MPH AT 4,400RPM'S IN OD
OR AT 117MPH AT 6213RPM'S IN DRIVE.
BUT UNDER MY TBI I GOT A 350. OR RATHER HAD A 350 NOW ITS GOINT TO BE A 406.

Maybe cuz you have a B4C option.

It's probably 117 on both Chevy and Pontiac. Speedos aren't that accurate at high speeds anyways.

yeah that's what i figured. there both set at `117mph.

Not intended to flame anyone or third gen.org but: I am a big fan of thirdgen.org but to me the guy who wrote this as well as thirdgen.org dropped the ball on this one. Wouldn't it be a cleaner job to just remove the speed limiter in the memcal. If you have a buddy with a prom burner and the software it is very simple to do. The limit set at the factory on the cars with Z rated tires at an unobtainable 255 mph.

Both are set at 115. At 100+ mph, speedo's arent perfect. You were probably only going 115 even if it said 117.

It would be cleaner but if you don't have a buddy with the stuff, well then it's no so easy. And if you have the switch somewhere like under the dash, I think it'd be pretty cool. Either way though...

It's easy to reprogram the TBI cars since the chip isn't in a large holder like the TPI cars and the later V6's.

I reprogrammed my friends 91 TBI Bird when he went from 2.73 gears to 3.42. He'd hit the limiter at 92mph since the ecm was still reading 115-117 due to the gears.

Hahaha Yah thats true

a tpi 350 wouldnt have a speed limiter would it? Ive never taken the car over 120 mph so i wouldnt know.

Just want to say wow! thanks for responding with so much info, i am glad i found this site....:cool: lots of amazing info on here, i will be back to ask more ?'s in the near future....till then keep'em between the ditches:D

The TPI cars will hit 140.

-Rippin . WELL AUCCUALLY IT READ 117MPH BUT I WAS DOING 122MPH.WITH 4.11 GEARS WITH 295/50d15 HOOSIER'S.SO IT WAS TURNING 4,400 RPM'S IN OD.

yup..143 in my g92 LB9..i coverd 12 miles in 5 1/2 minutes

and im guessin 150 or so drafting a L98 vette

it was cool as hell...i "felt" the car start pulling harder once i pulled in behind him


the speed limiter was determined by the tire rating...but you guys knew that lol

really.....

yes really ain't that so cool when corrected the speedo toi the 4.11 i swear i go send the sending unit for shorter tires but 295's are 26.6inches tall instead of the stock 25- 26 inches depending on if there 16's or 15's. 235/55r16's = 25ish 215 65r15's = 26ish.

ive owned my camaro for about 6 hours now (lol).....my s10 cuts out at 97ish....i didnt even think about a limiter being on a camaro at all! the ASE chip gets rid of the limiter in my s dime, is there a chip available to do the same thing in my 88 camaro?


ps....if i say something retarded in the future its because i dont know too much about camaro's.....i know some but not much..........my bro has an 87 trans am and i end up teaching him about his own car, i know maro's and f birds r very similar but ya know how gm screws things round when they sell a car under a diff name......this is y i say i dont know camaro's that well......thanx again and please...HAVE PITTY!.......lol j/p
