I was wondering what is the maximum speed you could go in a vg 5speed in 2nd,3rd and 4th gear as my speedo doest work

 

It might be in the owner's manual...i remember i read the manual for an old bmw, and it was in there. I can check mine.

Or if there are any math wizzes on the board, they can do the rpm/gear ratio/tire size thing.

 

3rd gear for my VG auto is 115 MPH.......1st gear is 40 MPH...2nd is 75 MPH....3rd is 115 MPH but that is my auto... i dunno if a 5 speed is different.. i imagine they are similar

 

FSM has it I think.....

 

5 speed and auto are WAY different, one has 34 gears, and the other has 5 for one.... if no one posts it up before i get my car fixed i'll do it for you, what do you want how fast i'm going at like 6k?

 

Ill have to dig out my manual. but 3rd is something like 90-100, 4th around 115-120 and 5th....to top out 5th in redline I think its just theoritical. I know frist is about 32 or and 2ed is 63 or so. But I havn't driven the max in a week.

I know when My speedo was working 5th tops out at like 147 to 151 some where in their. But any how i though third was at about 90 ish.

 

6,000 rpm redline
235/45/17 tires

1st - 38 mph
2nd - 67 mph
3rd - 97 mph
4th - 130 mph
5th - 156 mph

Reverse - 36 mph (just for the heck of it)

 

I hit the limiter and my speedo said 115 in third...do I need a new speedometer?

 

hey mark are you sure about that? I can go like only 60 in second with 225/45/17.
this is what I remember when My speedo work
1st 30
2nd 60
3rd I want to say 95 not sure though
4th no clue
5th was like 147 to 151 guessing as i pegged the ve gauges in my vg gxe

 

Going by your tire size 225-45-17 it should be:

1 - 37
2 - 66
3 - 96
4 - 128
5 - 154

Tire pressure can change the speeds but most likely, the guages are probably just slightly off.

You know what... I just remember you had the VE tranny... this is what yours should roughly be:

1st - 35 mph
2nd - 63 mph
3rd - 92 mph
4th - 122 mph
5th - 147 mph

@ 6,000 rpm with 225-45-17 tires

Speeds will also vary a little bit due to fuel cut being around 6200 rpm or so.

 

ok well how about this one.
I ran at the track with my Z wheels
225/50/16
what would be the mph on the gears on that one. And does that put me at a better gear ratio for the 1/4 with that tire/rim combo than My street tires size 225/45/17

ok Also I ran at the track on saturday and I had the street z tires and rims on the front. I did my previous best time on 10psi with no cams or head work. I ran a whole second slower than my previous time at 9psi with cam and head work due to spinning. when i shifted to 3rd gear they starting spinning bad. My 1/8 was like a 9.5 but yet the 1/4 time was like 14.2. Well I know that im making more power at 9psi with a very rich air/fuel ratio. I could not get a kock level over 18 at the track ....thats very rich to me. But yet the tires would cut loose in third. So I need tires and a tune before i will return to the track

 

For my references:
1st= 3.285
2nd= 1.850
3rd= 1.272
4th= 0.954
5th= 0.795
Reverse= 3.429
Final Drive Ratio= 3.650

1st= 3.285
2nd= 1.850
3rd= 1.272
4th= 0.954
5th= 0.795
Reverse= 3.429
Final Drive Ratio= 3.823


6000 rpm, 225-50-16
1st - 35
2nd - 63
3rd - 91
4th - 122
5th - 146

 

Does that put me at a better gear ratio for the 1/4 with that tire/rim combo 225/50/16 than My street tires size 225/45/17 ?

 

I'm not sure actually. What are you speeds in the 1/4 right now?

 

well thats hard to say right now because of spinning so bad but my best was 105 before now its like 104

 

Actually, now that I look at it again your street tires are only .1 inch bigger than the tires you're using for the strip.

I don't know a whole lot about the best gear ratios for the drag strip but I know you want to at least keep it so that you don't have to shift while crossing the 1/4 mile line. If you start getting up to the top of 4th and need to shift right near the end of the track I'd probably go with a slightly larger tire. Hopefully someone with some more track experience can chime in though because I'm not 100% sure.
