Nitrous practicality and reliability

[CAYOTE]

Best has been 11.32 with 1/4 tank of E40. DA was negative 500ish.


3.15 rear, 275/40-17 Hoosier DR2, I'm using the 18x5 OEM spare rim with a Kumho 135/80-18 tire as the front runner. With Passenger and rear seat removed along with the optional spare/jack nets about 175lbs weight reduction.

Upping to a 125shot, I ran a 10.54, Started spraying at 2800, It skipped 2nd, short shifted 3rd @6600 and I tried manually shifting to 7th to avoid the 6800rpm 10R80 6th gear limiter but the tranny still shutdown due to an overspeed condition, All that cost me a a quarter second I'd guess.

The fluid level is good in my 10R but it does not like the extra power.

I'm coming up on 25,000miles so I'm going to change but I have doubts it'll help with the wonky shifting.

Even with tuning my 2018 Gen3 had the same wonky shifting issues on a 150shot ...

Not bad. My car has been a best of 7.43 in some good air. I’ve found one thing that seems to help with the wonky shifting is I will manually shift to second and then put it in drive and let it do its thing. I only run the 1/8th so I don’t have to worry about 6th. I’m gonna take the seats out and run the 7.50 index this weekend. I’ve also heard that they are having to manually shift the cars when they are spraying them. If I ever get a free weekend I’m going to put my kit in and start testing. I’m the only S650 that runs at my local track so I’m expecting to get a little attention whenever I start breaking into the 6’s lol

Even with the 3.15 gear I've found it's impossible to manually make the 1-2 shift on spray, the engine just spins up too fast,, the 2-3 is doable but I find myself tagging the limiter most of the time,

That other slip was me tagging the limiter in 2nd trying to manually shift.

Normally I put it in drag mode and leave it in drive for the 1-2 and 2-3 upshift, then drop it into M and can usually hit the shifts at 7400.

I picked up one of those Maximizer EZ Progressive relay's and may install it and bring the spray in at 2200 and see what that drops the 60ft to. I'm still on the stock axles so I don't wanna shock those things too hard.

Good luck and use high octane gas ...

Yeah I bet it is pretty hard to manual shift it on spray. I’ve got 3.73’s in my car as well. As far as octane, I’m gonna run C25 in the standalone and probably a little boostane in the cars tank.
