850 na tb mod

I did, the 96 GLT that I crashed. Same answer - press the pedal a little further down. Or not. More travel equals more control, so you can more precisely choose the amount of power delivered, during clutch engagement or otherwise. We're talking about what, an additional 1/8" of pedal travel?

The numbers say it's a meaningless change, I really don't understand why it has such psychological impact on people. 120 ft-lbs of torque is 120 ft-lbs of torque, whether you depressed the pedal 1" or 1.125" to achieve it. The payback of leaving it alone is that you have meaningful control of small amounts of power. I find this most useful when I'm using the throttle to modulate body roll, thus rear steering, in sweeping turns.

You've got you're opinion, I have mine. There is a lot of people on this forum that have done this modification and are very happy with it. Changing the throttle plate improves response and control especially when you're driving a stick. If I wanted a dead spot in my gas pedal I would simply put some slack in the throttle cable. There is no point in having that plastic chunk unless you're incapable if moving your foot in small increments. The 960 did without the plastic chunk along with every other volvo ever made. I say it was a cheap marketing gimmick that failed.

Hey, do it if you like. It's your wheels.

But - no, it doesn't improve response. It just makes you, and a lot of other people, think it does. Sensitive throttles are apparently popular, or else all the manufacturers wouldn't be doing it.

It's also not the same as a dead spot; the plate lowers the minimum amount of off-idle airflow. A slackened cable simply leaves it at idle for the top part of the pedal travel.

Put the shoe on the other foot, so to speak - there's no point in removing it unless you're unwilling to move your foot in a larger increment.

Comparing to the 960 and other prior Volvos' lack of the plate is a formal logical fallacy known as "appeal to tradition". These engines are nothing like the older ones. Also, honestly, saying it's so because so many people say it is so, is "argumentum ad populum", or "appeal to belief".

But like I said, if it makes people happy, go for it... I just hope you're not behind me at a stop light when you're teaching someone how to drive stick.

Thats an interesting theory. Please explain how that works?

You mean it reduces the airflow by 50% then suddenly gives it back to you 1/4 of the way down. Thats brilliant, lets do it to all cars.

Maybe you're on to something. Hey I know, why don't we reduce the initial brake pedal response by 50% or make the steering 50% slower. You know you're just being lazy if you don't want the shifter to move another 50% further.

Really? how is the 960 engine not like the 850 engine. I can't wait to hear this.

You really are grasping at straws to make weak argument.

Stop it or I'm going to lock this. The point has been made - removing the lip from the plate increases throttle response before you really get your foot down. To the OP, it's up to you if you want to change out the plate or not.

If you do, make sure to remove the battery cable and drain the charge from the ECU to let it re-adapt to the new airflow/throttle position sensor readings it will be getting without the restrictor in there.

[kcodyjr]

To the OP, what jblackburn said. If you do the mod, this is a good opportunity to clean everything out. I'd suggest doing it at the same time as a PCV replacement, and also order a throttle body gasket, and maybe vacuum hoses at the same time.

To jblackburn, thanks. I have only one pressing concern in the matter, and that's the idea that it improves control. That's mainly applicable to the automatic in bumper-to-bumper traffic - Storrow Drive, I'm looking at you. In retrospect I can think of one positive effect in a stick; it probably makes it harder to stall, and the added twitchiness is compensated by the left foot.

To tjts1, if you still want to hear my answer to your last, send me a private message.

[tjts1]

To answer the original question, this is why you can't just remove the plastic chunk from the 850 throttle plate. Its just a matter of finding a 960 in the JY.

Nobody thats done the modification has every called the throttle response twitchy.

lol thank you guys didnt mean to cause beef just wondering because i do have a 5 speed and its just annoying in stop and go traffic and when im trying to race someone because out of no were the rpms will shoot up and start spinning tire in first it seems like the throttle control would just be more comfortable and launches would be a lil cleaner could u plug the hole in the plate if u remove the plastic and what would be safe to plug it with i know this does not increase hp or trq just throttle response i dont believe i ever said it gave you hp so dont fight over if it does or not ur stupid if u think it does it just less restriction and better air flow does anyone know were i can find an adapter for my cold intake for the MAF sensor as of now my setup doesnt look all tht pretty but it actually sounds amazing

[tjts1]

I suppose you could use a couple of screws to hold down a metal plate over the hole but you know if ever comes loose thats going straight into your engine. I've seen dozens of 960s in the JYs over there. There is really no need to half ass it. And yes the throttle response with a manual trans and the plastic chunk is really annoying.
good luck
