I'm getting ready to store my rx7 for the winter and I have a question that may be pretty simple to answer about my first gear pull. When ever a light turns green I always feel as if I have to give it more gas just to keep up with the other cars. In second gear there is no doubt that if I give gas it will pull but my first gear as always fells like it has less torque. I am also not sure if I am the only one with this issue, so does anyone know why every gear has torque besides first and fifth? I have BNR stage 3 sequentials

 

None of the gears have any torque at low rpm. When you start out in first you are at low rpm. Most of the time after shifting, you are at higher rpm than when you move from a stop.

The important question is: Does you car accelerate properly above 4000 rpm in 1st gear?

 

I had a line off the front vacuum tank and it made the transition @4500rpm sluggish so sometimes in first it wouldn't come on.

 

He's talking about low end torque and drivability not a WOT 1st gear run.

Is this your first standard car? Keep in mind, now you have to shift, whereas every other car on the road is an automatic and it shifts in less than a second. Driving from stop light to stop light I'm always losing to mini vans and what not to get up to speed. Partly it's my grandma driving, and partly its because everyone else is automatic.

If you feel your car is running INSUFFICIENTLY in the low end, maybe we have another problem. Id your air pump deleted? Your air pump has secondary injection air in low end and idle. If its not properly deleted, then you will run rich at idle and low end.

It's still fast above 4000 but it wouldn't break traction where my second pushes me back into my seat hard

 

Yeah it's my first standard car but I'm good at shifting I know I'm not as fast as an auto but I still get left behind unless I give it more gas, my car does run very rich in all gears, but I will check out if the air pump was deleted or if it was delete properly as I am not sure

Thanks, and it's atleast good to know I'm not the only one getting left behind by minivans lol

 

It sounds to me like you are bogging the engine by not giving it enough gas as you are releasing the clutch.

 

I have a stage 3 bully clutch, I could try giving it more gas but I already release it at 1000 to 1500 :/

 

1000 to 1500 is pretty low on every rotary I've been in or driven. Granted I've never been in an FD, so maybe it's different. Around 3k is where my car likes to be for a smooth start.

You can tell you're not giving it enough gas if the car is jerking. There are probably other ways to tell too, but I dunno that's how I tell. If your start isn't smooth and the car is jerking/bouncing you need to give it more gas.

 

Truth.

 

So you are saying your frustrated because you have to try to beat mini vans away from lights during normal acceleration using a racing clutch?

Let the vans win your ego will be ok... I think you are under estimating the driving aggression of a soccer mom in her mini van, they are generally in a rush to get some where.

 

+1

Race clutch + Low rpm + Rich at low rpms = Bogging.

My car doesn't like to take off smoothly anywhere under 2.5kish, and that's with a stage 2+ clutch.

 

Thank for what you and everyone else said that seems like that's the solution, now I just have to get used to releasing the clutch at 2500 to 3000

 

Lol that's a good suggestion on why mini vans take off on green lights

 

lol talking about mini vans on rx7club -.-

 

I think the answers are getting over complicated.
To the OP, have you watched your boost gauge? In first gear it's difficult to make much boost regardless of rpm because there's not enough load. I think that's why you don't feel "torque". Second, and subsequent gears, it's much easier to see boost...and more of it.

 

Releasing the clutch at 2500+ rpm on the street? Um, completely unnecessary and will lead to accelerated disc wear. Around 1000 up to maybe 1500 sounds right for a modded FD w light flywheel.

 

^ Agreed, I think people need to practice driving stick.


I have one of the lightest flywheels available and an unsprung hub clutch and can take off from a stop light at less than 1500 RPM all of the time.

 

So 1000 or 2500 ? because I have been driving my fd for 2 years releasing at 1000 to 1500, at 1000 it sometimes Boggs a little because of the stage 3 clutch and lightened fly wheel.

Either way ill probably be the slower ones leaving a green light unless I give it a lot more gas, if there isn't enough boost in first gear is this the issue?

Thanks for the responses

 

What ecu do you have? who did the tuning?

It may be an issue with the tune. When I first installed my Haltech the low rpm cells were too lean and caused a bucking/stalling issue making it look like I had no idea what I was doing. I had to rev the car and engage the clutch at a much higher RPM, same as what you are doing. Once I richened up the cells the drivability was significantly improved.

 

Look at it this way Fd3s guy, when a lightend flywheel and a racing clutch are used its not going to drive away from a stop like a stock car. Thats just the how it is.

If there is an issue with the power deliverly, describe it a little more.

He has a PFC ecu. Thewird tuned it.

 

Did anyone else just hear the "dark side" calling fd3sguyy? Use the torque Luke
Joking lol

 

Yeah I'll just have to deal with the the drivability, about the power delivery, if I step on the gas it'll rev smoothly and quickly to redline but its nothing like the kick I get from a second gear pull. I never really hear a bov sound either tell you the truth. Some one here said that in first gear there isn't as much load but are my turbos not spooling or not spooling enough?

 

It isn't a huge issue but sometimes i want to be pushed back into my seat in first gear like I am in second.

 

In first gear your turbo control actuator actuates earlier to compensate for the fast rev of a first gear WOT pull. If you have issues with your pressure or vacuum chambers, check valves, or solenoids, then you might not be getting full boost in first. As well as experiencing a slow transition in other gears. Do you have a boost gauge?
