s what am i look at in times and accel with a b16 and ls tranny just want to see how its goin to perform does anybody know what its goin to be like

 

bump

 

Well it would work, but everytime you shift your RPMS are going to droooooooooooooooop, so no mad VTEC racing for you good sir.

 

Yea but hey at least you will save gas while racing.

 

why would they drop on my ls i shift at 6800 and it drops to 4500 to 4000 so i dont think thats out of vtec

Having your next shift that isn't fifth drop you from redline to sub 5000 is detrimental.

 

dont sorry about it, ls trannys have really long gears so while others are shifting you are still ripping. if you want to rev real high, long gears are the way to go because you have more time to rev out.

 

thats what i figured i was just lookin for someone to say thats what they did and r very happy with it

With a higher numerical gear ratio, you are putting more rpm at the wheel. With closer gear ratios, you are able to stay at a higher rpm in between shift points. Something like the LS transmissions are suited more towards the broad torque curve/low reving LS engine. It keeps you in the peak torque area in between shifts. The ITR/SI/GSR transmissions keep the rpm's built up in between shifts, to stay in the more peaky powerband.

Having said that, for the track the itr/si tranny is the best hands down. Most high whp turbo engines are operating between 5.5-9k, and having their shift points in between. In combination with a tall slick size (24.5"+), and the high shift point (8.5-9k), you are able to keep the engine operating within the optimum torque curve.

With the LS transmission, between shifts it would possibly drop you out of the optimal powerband and therefore make you slower. Gearing simply put allows you to stay in the powerband of your engine in between shifts.

The myth that you stay in gear longer with the LS transmission makes you faster is purely false. Think about that statement for a second. Acceleration is the measure of velocity over a unit time. Watching the rpms climb on the tach during a 3rd/4th gear pull, they would be climbing slower than with the si/itr tranny. Looking at the definition of acceleration as a measure of velocity over a unit time, the engine would be getting to the same velocity over a slower time lapse. This would yield slower acceleration, and simply put make you slower.

Having said that, the gsr transmission is probably the best balance of a street/strip transmission. The gearing is a little less aggressive as the itr/si transmissions, which will yield a little more traction. For all out acceleration si/itr tranny wins hands down. For a slower car, go with the LS transmission. </TD></TR></TABLE> http://forums.evans-tuning.com...ssion
