Copyninja Street FD - GT3 Build

[Francob]

The weather’s been awful lately, so I haven’t had a proper chance to get back out in the RX7. Managed a few short runs in the M3 during some damp, cold patches but with almost no traction, I wasn’t about to risk pushing 30+ psi in the RX7 when even the heavier, lower-powered M3 was struggling to hook up.

Good numbers for a E92 M3 considering conditions were not ideal. However, if my RX7 ran these numbers at low boost - I'd be throwing the draggy and my RX7 in the river! View attachment 42662

On a related note, curious what everyone’s running for engine oil and premix on high-boost, high-power 13Bs? Always interested to see what’s working. Anyone know what Mazda's race teams were using?

I use valvoline 10/60 and Millers KR2T premix

nice one and thanks for sharing.

Are you using the 10/60 because of semi p and the nature of the high revving rotors? how much premix are you using

I use it as I see much better oil pressure, it tends to break down a lot less (remember I have potential for a lot of meth) meaning I don’t need to change as often (although I tend to change regularly).

100ml 2 stroke per 10 litres of fuel.
