>10 PSI on Rotrex track driven NB2s
Is anyone running more than 10 PSI on their Rotrex 2001 plus track car? If so any issues when doing track days with our 10:1 compression and detonation?

I am doing that with a AEM FIC, but concerned going up to 12 PSI (with 75 mm pulley)might be a bit too much for track days since the NB2 engine is 10:1 compression

If you're concerned about the extra 2psi, pull some timing out. |

I have an NB2 engine with the AEM FIC running 10psi, so granted, this is not an apples to apples conversation because of two less psi, but my cars has 5k+ track only miles and so far...so good.

That's where I'm at now ....10 PSI. I also have many track miles without issues. Just don't want to have any if I raise the boost
How do you like the AEM FIC for as far as tuning? I still have a slight idle issue and have read that the Megasquirt may rectify this situation. |

Easy button for your setup is more octane. |

I ran 22 PSI on 10.5:1 with my whipple. With water injection. Now run 9:1 and more boost but no WI but more E85.

Not only do I have a number of E85 stations around my home, but the gas station we fill up at, next to the track I frequent, has it also
|
Unless things change by the time I want to increase the boost, at the moment there are zero public E85 fueling stations in Connecticut.

Fair enough! Please keep the thread (me!) updated as I feel 10 PSI feels sufficient for now, however, I do not think a substantial amount of time has ever passed without me wondering if I could squeeze any more power reliably out of a setup.
