08.5 vs 09 even match?

[2.0t03speed]

lol what do you mean used to they still do ahahah

The old Mazdaspeed Protege used to have the exact same problem it accelerated harder under partial throttle than just flooring it. Usually.

It's to do with how the turbo spools. Turbos work better under load, so they actually prefer a little bit of resistance when sucking air in. A gradual ramp up is and always has been the best way to drive a turbo car and trust me i have driven a LOT of them.

I do find that once the motor is good and hot the best way to drive it if you want to feel the greatest acceleration is to slowly feed the throttle in getting close to 80% at 4000rpm then flooring it at 5000 or so. Your metering the fuel with your foot. The idea about too much fuel is probably correct. You need to match the fuel with the amount of air going in.

But yes gradual increase = better turbo response. More often than not.

I'll bet the WOT just dumps too much fuel in. The car runs rich as it is, so maybe it's bogging the engine down with too much?

But then again, I thought even at WOT, our cars don't allow actual 100% wide open anyways??

I wonder if that is possible since our computer controls the fuel and throttle? Personally I hate electronic throttle control, it just doesn't feel as natural as my sr20.

I do agree that it drives better when it's not WOT. Usually I increase the pressure on the gas pedal as i am accelerating, i don't just hold the gas pedal at 90%. I find that the acceleration is much better that way. Anybody else agree or disagree with that?

I'll say the one thing i've learned with this being my first turbo car vs NA is that you definitely can't control the throttle or engine the same way as you do with an NA car.

im sure he's saying that he is suprised the MS3's have the same problem and has gone unfixed

 

[F430TECH]

Yeah I had a Titanium MSP before this. Except my MSP was BONE-STOCK...but I can't NOT modify the Speed 3. Power Gains in this thing are just TOO tempting...

Shhhhh... those pesky facts will give people headaches!

Someone should patent a nice billet throttle stop for maximum acceleration.

well two things, its most likly a difference in the drivers. And yes the motor mount would make a difference, but like you said it was off a rolling start, so its not as drastic as from a dead stop. One kid probably just sucks at driving. People are sooooo fast to harp on the machinery they operate, when 75% of the time its operator error.

 

[mazdasp33d]

but what would make the driver **** up? he didnt miss a shift, and was shiting at around 58

Humor has it that the 08's came with 15+more WHP and 25+WTQ due to revised ECU programming. The 09's didn't get the ECU revision due to new emission reqs, etc.

Yes

 

[clos561]

i believe they were both in 3rd at the 40.. so 85% is better then floored

why would 85% throttle be faster? thats less fuel, less exhaust gas to spool turbo????? dont get it, i disagree

 

[240ka]

85-to-90 then gradual floordoes work

i think flooring out the gate may throw too much fuel and isnt mixing with enough air.

 

[MicaSp33d]

all i can say is that one driver is a faster shifter than the other. A few slower shifts can equal a car length because the other guy was in the next gear faster which means he was already continued to accelerate while the other guys just began to get into gear and accelerate. Both cars are probably evenly matched but a few of those and you will lose. Also its proven that when a car is fully broken in, it gets faster. Road & track had an article where they tested the cars new and tested it about few thousand miles later ( don't remember how much) and it was about a tenth quicker.

If you really want to find out ... have the drivers switch each others cars and see who wins haha ... now that would be interesting.

it this true?

 

[Kain]

it this true?

I lawl'd.

 

[mattj3636]

at me or at what the kid said... haha

im being serious, i really dont know if it is or not

 

[mazdaspeedster3]

It is not true, he was being facetious...

Speed shifts make all the difference as said by Micasp33d. You can win races against much faster cars shifting faster, everyone knows this.

 

[mattj3636]

shifting faster and at the right time indeed, and who was the one beeping, cause there normally the one to take off that split second faster, causing him to pull on the kid, but shifting before him, causing the other kid to pull hard on him.. if you catch my drift lol

 

[pmeilakjr]

Switch cars

Have the drivers switch cars - then see if the 08 still beats the 09.

Cheers!

[AzNGraDz]

I second pmeilakjr...

 

[mazdasp33d]

the kid cant do it now, the kid with the 08 totalled it
