B15 Vs SR16VE Vs SER Gear Box Comparison For NA
All MPH are calculated at 8000 RPMs with 23in tire.
This is for all the guys who keep saying SR16VE gear boxes and B15 gear boxes are the same. They are not.
SR16VE gear box FD ( 4.44 )
1. 3.333---14.788 = 37 MPH
2. 1.955----8.674 = 63 MPH
3. 1.333----5.914 = 92 MPH
4. 0.975----4.326 = 127 MPH
5. 0.756----3.354 = 164 MPH
B15 Gear Box FD ( 4.44 )
1. 3.333---14.788 = 37 MPH
2. 1.955----8.674 = 63 MPH
3. 1.286----5.706 = 95 MPH
4. 0.926----4.110 = 127 MPH
5. 0.733----3.252 = 169 MPH
SER Gear Box FD ( 4.18 )
1. 3.063----12.791 = 44 MPH
2. 1.826-----7.625 = 72 MPH
3. 1.286-----5.370 = 98 MPH
4. 0.975-----4.072 = 131 MPH
5. 0.756-----3.157 = 174 MPH
As you can see the B15 and SR16VE gear box share the same 1st and 2nd gear for quick acceleration. Please note they share the same FD also.
For highway driving the the B15 gear box beacause of its longer 4th and 5th gear which is identical to a P10s 4th and 5th gear will give you a reasonable compramise for long trips as compared to a SR16VE gear box.
Basically for NA the B15 gear box gives you the shorter 1st - 3rd for 1/4 mile racing but still gives you a good 5th gear for highway driving.
In conclusion B15 gear box % wise is a better all around gear box vs SR16VE gear box if you are looking for the best of both worlds acceleration and gas mileage.
