What tranny do you guys use or prefer for boost? looking for 450+ Whp
Or would you re-gear a tranny?

 

i love my B16 tranny on my LS motor

 

This poll is kinda silly imo. The B16/ITR has the same gearing, so there shouldn't be 2 seperate categories for them. Also a custom geared transmission to fit your specific setup would always work better than a stock honda transmission, since everybody's setup isn't the same. This thread will probably just end up in a BS match.

depending on the year of the type r. they have a higher final drive.

im using a b16 tranny with 420hp/312tq

 

GSR trans

 

how do y6ou like the b16 tranny? i have one just haven't installed it, some people say they don't like it with the high horsepower. What gear are you in by the end of the track?

 

Ive had b16 and gsr and i like the b16 better.

 

I like my LS tranny.

I agree for the most part. It is a preference. Here is what Jeff Evans said a while back....
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by boosted hybrid &raquo;</TD></TR><TR><TD CLASS="quote"> Gear ratios are merely a way to trade torque for rpm. 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.

Now I don't know if he still thinks this way, but that was his reasoning at that time. I have also heard some good justifications for using an ls tranny. There are a lot of really fast cars that use all of these (ls, gsr, b16/itr) and have very good results. Try a couple out and pick which one you like best....

Edit: I am running a gsr tranny in my car.

I have an LS on my GSR and I HATE IT, the damn car goes almost 80 in 2nd gear around 91-9200 rpm. You have to shift it that high to get the RPM's to stay over 6k. If you shift at 8k, the car bogs out/falls on its face and falls out of the power band, the only beneficial thing is I can cruise @ 80mph at 3400rpm

 

i have a ls tranny in a ls.. Love it..

 

i love the b16 around the city. but when it comes in the highway. thats another story...

 

i love my gsr, but have recently gone to a gsr trans w/ LS final drive, for a little better traction hopefully. depending on what slick size or tire size, you could basically change ur FD by changing the tire size

 

thanks on all the post keep them coming.. for all you ls tranny users what motor are you running and what is your whp and rev limiter at ?

 

I am running a B18C, I was at 300whp before..... stock head so it was 8k

Same engine, fully built head, prob double the hp..... awaiting dyno but I will prob shift in between 9000 or 9500 depending on my torque curve etc. I will be ditching the LS in favor of an ITR gearset or GSR with the LS 5th for the cruise, i figure that switch right there will be worth .5 sec in the quarter over the LS in my car.

IMO- take the LS fith out and use the rest as a door stop.

the b16 and Gsr are very similar but not exactly the same.

...B16 with an ls fith and Quife LSD and your good

Thank you you seem to be alot of help to me ..

 

i have a ls motor now with the GSR trans, and pretty much hate it.

Im CONSTANTLY shifting gears, even on back roads im in 4th or 5th gear. (i usually hit 5th at about 45mph) which i think is shifting out of 4th at like 3k or a bit less.


before i go ahead and slap my ACT clutch in im searching for a good LS tranny to ditch for the GSR.

 

i have 2 ls gearsets. PM me if interested..

send all your b16 hydro trans to me

 

i need some too dave hehe
