Just came back from Track, ran a new personal best [email protected] on 100 Octane, 30 PSI and Full weight (Minus Headlight),
heres what I have done.

Virtual Works 74MM Kit
Virtual Works Intake Manifold
AEM EMS
Stock block, head, cams, sprockets, Everything internal Stock!!
30 PSI on 100 octane
26X11.5X16 ET Streets on RX-7 Stocks (Rear)
16" CCW front


Like to thank Ben and Dana from Virtual Works for helping me tune the car, Tony and the crew from Final Stage for all the help getting the car together all week, and real special thanks to Elliott Nail, if wasn't for his help last minute with the Blow off Valve, never would've ran this time (Old blow off was leaking). Hopefully get Video up soon.

Ya, the weather was super cold so I think I got very lucky, no detonation at all. Orginally since is the last time out with the stock motor, we wanted to try C16, between the tires getting here late and had some issues with mounted all 4 wheels, we ended up with 100 octane which was the same tune from previous week so we knew it would be fine. But if we had C16 we would've bumped a few more on timing and couple more psi, but Im happy can't complain.

The week before I ran with my 18x9 volks up front and the car was all over the place with a [email protected], thought I lost controll a couple of passes too. Last nite with skinnings up front was insane difference, the car was soo straight I was in shock. RX-7's are 8" wide so is works fine with the 11.5 tire, no problems at all top end. Caught a 1.52 60 the pass before too.

Congrats!!! Welcome to the club. What clutch are you using?
Forgot the name of the manufacturer, but is the Feramic I think from HPC or something. Made over 60 passes and still holding, this clutch loves to slip, but I'm also not putting out near the power of some of the other guys, we estimating only at about 780 or so, so put this clutch in 1000 hp car not sure what it will do.

Congrats on the great pass.

Why does everyone think you need to use c16 to make power?

I have been making more power recently on VP105 since I'm on stock ecu, without the ability to bump up the timing my car dogs a bit on the c16.

On C16 I also need to run extremely small plug gaps and driveability sucks.

Next time out try the VP105 its still unleaded.

I have found the key to making the lower octane fuels work is to make sure your not mixing it with any pump gas, it needs to be pure.

I know most people on here go to the track to run as fast as they can no matter what.

And for you guys the C16 is key.

I for one use the track to make my car faster on the street, so using C16 which makes my cars driveability suck doesn't make sense.

Sorry for long post,

BIG CONGRATS on a good run...:D

OT: If you pull the efi fuses and reset the ECU w/ C16 the ECU will bump the timing up for you. The stock ecu get's pretty aggressive. I've seen as much as 23-24 degrees of timing.

I do that, but have never seen that kind of advance, not at peak torque anyway.

I edited my post in anticipation for some flaming so you may want to reread.:)

I like tuning on VP105 since I use it all the time on the street and it doesn't harm the sensors.
