Power shifting?
Saturday, March 26, 2005 12:04 AM
Was curious what ppl's opinions of doing this is? Or can you do it with out grinding gears?


On a different note. Does anyone know where to get performance gears and what not for tranny's? I believe the sycros are going in 1st, 3rd. And if i have to rebuild a tranny I want to have it beefed up some if at all possible.

Disclaimer: If gonna flame for thing my tranny is going bad because of power shifting. Which I'm sure some are already going to assume. It actually is shifting better with out the clutch being used. LMAO. And it was already rough when purchased during last summer.:-d

Power shift with a cable shifted trans is a hard thing to do, you dont get a firm solid feel like a linkage shifter thus making it near impossible(you just cant put the same force behind a cable as a linkage like needed). The syncro's will also stop you in these transmissions. I used to build racing manual trannies and took out every second tooth on the syncros also did some other misc machining, went down the track with my foot to the floor and no clutch bang'n gears. DONT do it on a daily driver, these trannies had to be gone through way to often as its VERY hard on a transmission.

your best bet is to slip the clutch. when i'm @ the strip i never take my foot off the gas i'm at 6K my foot to the floor i just "bump" the clutch when i pull it and slam it in the next gear, the RPM's dont even have enought time to hit 6500 before its in the next gear. hard to explain in words put you push the clutch JUST enough to get it from one gear to the next. makes for interesting shifts when you burnout through second and squeel on the third shift on a stock twincam.

You'll have to play around and see what your car likes best and see what you like best.

i speed shift/power shift my daily driver on a reg. basis. Actually I thi8nk it shifts better not using the clutch than it does using the clutch right now. If that makes anysense. It isn't so much a matter of force but a matter of matching rpm with motor speed for it to slip in gear.

your talking about a whole nothing thing there, thats not a power shift, try slamming gears on your jbody while racing doing that and tell me how many gears you make and how many races you lose. thats not a quick way of shifting and really not needed. its hard on the syncros as well.

Exactly !!! Save your transmissions boys. Unless of course you enjoy spending 1500 - 1700 dollars for fun replacing your tranny.

I was under the assumption that powershifting is not letting off the gas, stabbing the clutch and shifting really fast. I dont get where the no clutch comes from. From stang drag days
