Evening all I was wondering if anyone had any tips on how I can improve shifting times or hold gears longer I am trying to see how fast of a 0-60 I can get.

Currently I have to change to 3rd for 60mph as 2nd is topped out at around 56-57 mph any ideas to reach 60mph in the 6 speed?

I have about 420 bhp and have a 0-60 of around 4.2 seconds with LC and anti lag however I am sure if I didnt have to shift to 3rd I would be under 4 seconds to 60.

Get flat foot shifting mapped in, no need to let off then

Have it mapped witb a higher rev limit. Your risk though.
The big question is why? 0-60 is an arbitary time selected by road testers decades back. In those days it was representative of everyday motoring. In these days of sub 3 second times, much less so. It makes no difference to how the car actually drives. I've seen a professional road tester go for a 0-60 time. It's horribly cruel and not something I would ever do to a road car.

Already have flat foot shifting mapped on but I am trying to not use it unless no other option.

With regards to the 0-60 I am trying to improve my 1/4 mile but Its very difficult to do that with santa pod closed and would like to avoid trouble from the local constabulary.

my car accelerates very rapidly after 60 to about 120ish for the 1/4 as I have grip then.

Why don’t you want to use flat shifting? It’s great and should improve your 1/4 mile time by around half a second!

Danjo

The only way you are going to get around the 2nd-3rd shift is to raise your rev limit, but it would be recommended to have the heads built to sustain those higher revs.

Akram124

Feel like the wear and tear with LC is immense but 1/2 a second sounds insane ill try it when the pod next opens up or someone invites me to a private road

Akram124

any idea of a price range for having heads built to sustain the higher revs or better off just going to build a 2.1 stroker?

Danjo

It all comes down to what spec you want to build to, what you want to rev to, what turbo you will be using etc. If it's going to be a road car, you don't really want all the power in the upper revs as you'll sacrifice lowdown torque. Likewise a track car never spends much time in the lower revs, so it's no good having a high torque engine that chokes in the higher revs.

Akram124

fair point Have no intention of tracking the car just want to be very quick in a straight line lol.

I find flat shifting is a lot smoother in a lot of cases particularly in a straight line, you might find the lower gears a bit jerky at first but once you’re off the higher gear changes will be straightforward.

which ecu are you running ?

Akram124

still running the stock ecu mapped by neil@slowboy looking to pick up a link g4 ecu

FFS and LC are not the same thing.

Akram124

Thanks I am aware of that.
I havent used both together as the risk to my car is above a level I feel comfortable with.

johnfelstead

If it's mapped properly there is no risk to the engine.
Obviously launching the car hard puts more load on the clutch and drivetrain than not doing so but a nicely setup LC can reduce that.
I've been using FFS for 7 years, LC for 9 years.

MrRtm

What this guy said, the ecu mapped properly can rev match for gear changes better than most of us ever could

Akram124

Ill give it a shot when the weathers better

Thought I would pop in on this one just out of pure interest...🤔
