Top Speed of B12

SuperSentra4203 · Feb 23rd, 2003, 03:51 PM

I am asking what is the top speed of a base model B12(GA16i). Mine had a 4 speed and I redlined the 4th gear twice. I know only part way through 4th is when it hits 105mph. The 4th gear is very long, it took my 5 miles to hit the fuel cut at 7000rpm.> I know it should be 6800rpm, my fuel cut was not always on mark, I hit 8200rpm once, I never attemped to do it again. My mods were as follows> open exhaust and intake, advanced timing(not too much) and no extra weight. How I redlined it, well, when theres a will, theres a way. I don't recommend doing it though.

Well when my Sentra was a little bit healthier I took it for a run on a long straight flat stretch of highway. My 1989 Sentra (GA16i with the 3 speed auto) hit a top speed of 160 km/h (100mph) on the mark. Ive been a little bit faster when going down hill but im not sure how fast because the guage stops at 160km/h.
The car could in theory go faster because it was only running about 4800 RPM at 160km/h. The car just couldnt pull any harder thoguh.

I was on the highway about a week ago and my needle was in the area that the 110mph mark should be, I also had a passenger and a couple of 12's in the trunk. I'v got a '88 2-door with the e16i engine and 4-speed tranny and it was still pullin' when had to slow down.

I've had mine at ~165 km/h, and it probably could have gone a little bit more. I have the e16i and a 5 speed.

148-ish kph with my E16i and auto tranny. Got to 4300RPM or so, but I ran out of space to accelerate. Although at the time I was running with bad tires and my alignment was off... WAY off. So I'm sure since it's been fixed I could go a wee bit faster.

Zoom zoom!

top ive done is about 175kph.... coulnt get a fix on it cuz it isnt there... (max160kph) but the liner was hitting real hard

... had to slow down, suspension is no longer existing in the back so is was a bit bouncing... i could have done a bit better i was around 4900-5100 rpm....

find you fuel relay and replace it with a horn relay and your good for a few more m/h

Can someone convert those to MPH please!!

I know 105mph was at about 5300rpm. 65mph is somewhere around 3500rpm. So it seems 1800rpm=40mph. 450rpm=10mph. Using simple algebra tells me 500rpm=11.11mph. So 7000rpm would equal 149.44mph. That seems quite odd.

I'd really like to know what sorts of speeds a stock Sentra/Pulsar can get with the CA18DE... I did a search but couldn't find much.

To figure out MPH from KPH and vice versa

# in MPH x 1.609 = KPH

# in KPH x 0.6214 = MPH

Thus, SuperSentra4203, your GA16i tops out at about (105mph) 169 kph and my E16i tops out at about (150+ kph) 93+ mph.

I know that the GA16i tops out at 105 because drag is at a standoff with horespower. I was lucky enough to push the car to the limit, getting into the powerband as I started down a grade. It took a lot of testicular fortitude to push it to fuel-cut. My calculations say 149mph, I highly doubt that. Can anyone figure out what it will do, using the exact rpm a 55mph, 75mph, 105mph if you remeber? My friend was curious, and I soon started to wonder myself. I'm thinking it's was around 135mph, I was following behind my friends Talon TSi, he said he hit 140mph.

I have done ~165kph with my GA15 12valve auto tranny.....and now with the SR20DE I reach 180kph and the fuel cuts...need something to get ridof that trip and count beyond 180...help!!!!!

Not many cars will redline in top gear. That takes ALOT of power, something we don't have.

Or drafting off of a DSM and a good tailwind down a grade on the freeway. That is the only I have been able to top it out. My question is to what speed my car is geared to. I know the 4th gear is a long-ass monster. My mom always asked me why is ran such a high rpm on the highway, but 10mph never mad much of a difference. That is when I taught her about powerbands in small import motors. I also taught her what redlining first gear felt like

Hey,
while were on the topic of top speeds, does anyone know how much the speedo is off at 160km/h (100mph)???

Not a clue. Are you asking as in you don't know, or if you know?
