Does raising your redline alter your top speed?

[The Godfather]

does raising the redline meen a higher top speed?? i would guess so as you are holding gears for longer??

but how does it all work? the gears in the gearbox are set to a certain speed/ratio so how would u get more out of it?? im confused lol

just say for example
top speeds in gears:
1st 70kph
2nd 120kph
3rd 160kph
4th 210kph
5th 270kph

if final drive only allows for a top speed of 270kph how could it go higher to accomodate the extra rpm???

HELP...!!!


cheers
Adrian

yes,

gear ratio's are fixed, not variable, if you rev to 3k in 5th you do 100kph, if you do 6k in 5th you do 200kph, if you do 9k in 5th you do 300kph.

* numbers are guessimates used for demonstrational purposes

what about in the lower gears? will the speeds be raised in 1st, 2nd and 3rd??

Of course. Tyre sizes also changes speeds per rpm

yes but not so much...... considering the gear ratio

um... in my GGSR its 7K at 100km 2nd gear....

100km in 2nd?? :shock:

was thinking the same thing :shock:

 

[mattrat]

im thinking the exact same thing lol,
fuel cut, power cut whatever the fuck happens to me when i hit 7500k in my ggsr is about 85-90 spot on

 

[EVO-00X]

Yeah the FWD's can do 100kmh in 2nd gear and boy their fun to drive when boosted :lol: I can get 100kmh in 2nd gear in the Mrs FWD Lancer with the Proton GTi engine in it at 7000rpm. And get this, its even easier to get 100kmh in 2nd gear out of my little 1.5 EFI CE Mirage runaround car :lol: .

Theres more to top speed than just raising the red line.

You need the reliability to get there and hold it there.
You need the torque at that high rpm to overcome the wind resistance.

He has a GT35R with 1.06 A/R hotside. I can't see that being a problem :lol:

 

[mannynz]

oooppppsssss

Go and do it then.

and i love my big single :lol:

ive never hit fuel cut in my GGSR

but i'll take a pik the next time thrashing the shizen out of my car.... which might be tomorow lol

Turbo's power curve usually cuts before hand so you dont notice or it hits fuel cut.... so lookin about max of 6.5k for the turbos which would be around the 80-85km mark

 

[to4garret]

are you two talking about rev limits?

 

[JayRome]

are you two talking about rev limits?

max speed VS rpm

 

[to4garret]

yeeea

 

[i2obert]

8600rpms is what i need to reach with 4.1 diff gears to hit 300kph and at least 576bhp i think it was to hit it inless then 2km

 

[EVO-00X]

Now you just need a flat road to do it on :twisted:

As metioned earlier by mannynz the extra rpm will get you more speed up to a point where there just isnt enough torque to push the car any quicker Who here wants to push their car past 9000rpm?

 

[i2obert]

HAHA drstroked 2.4L down to a 2L and you should be able to REV Paast 9000 HAHA

and EVO-00X i already have 2km of flat stright surface to do it on just going to take me a while to get everything sorted mainly the transfer case issues with them blowing under launch
