Damn good info! ^

 

An Automatic transmission is the better choice for drag racing for most people. You will have much more consistent Launches and consistent times down the track. Your RT will be the non constant variable.

 

All Manuals need for it is an Anti-lag flash.

 

NO WAY. They made a transmission that shifts for you? Like... no levers or nothing?

 

The thing you have to worry about is heat. Heat will kill an auto. You can't do back to back runs all the time. You have to give some time to let the heat die down. And a tranny cooler is a must, but is not the savior.

I used to go to Sears Point to race in the bracket drags. I made it into the top 6 once cause I had my ET dialed in perfectly and nailed every launch perfectly. I just happened to go against a 60 year old man who know his car better than I knew mine.

 

So do you think the guy in the vid had a high stall since he was manual shifting the auto transmission? That Wrx does seem unusually fast for stage 2 against a 5 speed lol. Watching the vid I noticed no miss shifting by the Civic, seemed like a clean run. Also the Civic got the jump hahaha the Subies wheels were not in motion when the Civic launched.

 

He could but not necessarily. On the stock turbo, full boost can come on at 3000. I've held the stock converter to about 3200. I gained a 1000rpm by having the converter modified, but it changed the way the car drove. Everybody says the valve body is hands down the best. That is where you will see a noticeable difference when manually shifting. I just never had the time to have my car down for 2 weeks while I sent my valve body out to get modified.

And I've pulled many 5 speeds, even against other WRX's, for the first couple gears since, 1st goes to almost 40mph and second goes to 80ish. When they shift, you pull. But guaranteed, they catch you when they hit 3rd gear assuming mods are the same on both sides.

 

Changed it for the better? How is the rolling acceleration?

 

Butt dyno wise, it felt faster. Shifts felt a little firmer. Rolling acceleration was really unchanged. I think the valve body mod would have had a bigger impact. Trying to accelerate from say 65 in second, it would not kick down to second. But it you got to 60, it would kick down into second and it would accelerate quickly. But I'd say with adding the converter and the lockup switch, it changed the 1/4 time from 15 something to low to mid 14's. So shaved a second off the 1/4 time.

 

I assumed it didn't make a difference from a roll. Thanks for the info. Can you point me in a direction to read about this switch? It sounds like 4th gear when the TC locks up for fuel economy, but I don't see how this would effect performance.

 

TC lockup inhibitor switch? - NASIOC

This thread talks about it a little. Almost all info is found on nasioc and most of it by the last reply RiftsWRX. He was almost the pioneer when it came to the 4eat as it pertained to the WRX. I can't tell you exactly how it worked to improve times and feeling. But when I've hit the switch at over 5000rpm, the car pulled harder to redline. But it also throws a trouble code, AT Oil Temp light will come on and stay on until you turn the car off. It really is only needed and should be used for drag racing. Using it any other time doesn't make much sense.

 

I'm assuming dude has more than just a TC, possibly a Valve Body upgrade as well.

 

Here's a light launch by my buddy. I believe he just the valve body and a high stall.

 

Dayum! That Subie is pulling hard. Dude shifting like its the end of the world lol

 

Bro, that's a 4eat at work right there!
