Right, but what I am saying is on *93 octane*, it shouldn't even be close to the stock fueling system constraints at that power level. I am running *E40* making more power with the stock fueling system.
Would be good to know the boost level the OP is running but I doubt it's more than 27.5psi...
No way should there be any sort of fueling issues on 93 at 450whp if tuned correctly.
I run E40 on a Pure700 making more power with a 100% stock fueling system.
5500 rpm @ 24.5 psi = 107* HPFP angle
6800 rpm @ 27.5 psi = 103* HPFP angle
max HPFP angle is 126*
At that boost/power, LPFP is...
Well, everyone has their own comfort level. I can say I drove 2 hours through torrential rain on the highway and made it to my destination in one piece, I just needed some stiff drinks after arriving. ;)
Of course. No issue. Grooves are only for water evac. However, I can tell you, even brand new at full tread these are hairy AF in a downpour.
@kaj how many days on that tire?
Here are my V2 after four track days:
Amazed your cars don't feel like oversteer machines with no toe-in in the rear. Probably because of the very small amount of negative camber in the front.
Project Mu all the way. Don't screech like a dump truck, work fine without heat. It's one of the big reasons I love them. I did the whole "swap pads at the track" for years and it sucks.
I had not put a jack under the car at a track event this whole year until this last one when I got a pebble...
Softer up front can increase oversteer as front will have more grip.
For turn-in sharpness also take a look at your front toe settings. I found toe in causes some vagueness and going back to zero toe in front sharpened things up.
Adding more negative camber in front will be the single biggest...
You can setup the interpolation tables to bring everything down with higher levels of E if the fuel system can't support it at higher power.
Something like this, and setting the base tables as more of the neutered map. This is an exaggerated example of course.
I haven't used Cup 2's but most 200TW like 32 or so hot. I start at 26f/25r cold at track days with my Nankang CRS and usually need to bleed a little air out after the first session or two.
