Next time out it will have the new brakes, wheels & tyres. I'll also have all the springs rated to see what I have and adjust accordingly. Also planning to modify the existing strut tops for a little more camber, and then check all the roll centres. Finally, I'll tale the car to Andrew at Hyperdrive for a quick tune to make sure the engine is safe......plenty to do!

Nice times being posted! Good to see more s-chassis out on the track
Can hear that your engine is misfiring at higher revs, what plugs are you running? Mine used to do it when i was using 6 heat range at 35 degrees, once i've switched to 7s and cooler temps, it doesnt do it
Might be your coilpack as well

Times are still a bit slow, but lots of room left for improvement (My old SR powered Datsun Sunny race car was doing 1:07's).
I noticed the misfire also. Only seems to do it when the it's over boosting. THat's something else I'll get Andrew at Hyperdrive to check for me. I will double check the plugs though, I always used to run 7's in my Sunny - Good tip.

Dont worry about times too much as that will slowly drop when you get used to the car, i did a 1:13 when i first went to barb as well
I would stop going to the track until you get Andrew to check out the tune just to be on the safe side
Ideally swap the pfc out as it is not that great, it doesnt retard timing like the stock ecu when its pinging

Nice driving Mark.
Did you have your datsun over here or was that over east ?
Ichi and I do the wascc tuning days. welcome to join us at any time !
When are the brakes going in ?
Be interested to see how you setup the prop valve.
Did I see you picked up a RB25 dog box too ?

I will be certainly moving to the tuning dats soon, so look forward to catching up with you.
The brake upgrade has begun, and I'm re-thinking things at the moment in terms of which rotor to use. The Evo 10 rotor sits around 8mm further out, so I'm going to look at what other rotors I could use to get the rotor as close to the ball joint as possible. That will give me better caliper clearance with wheels.
No I didn't get the RB box. I'll be staying 6 speed.

Eventually, the ECU will be replaced with either a Motec or Haltech Elite. I ran Motec in the Datsun Sunny, the data logging is awesome for analyzing your driving.
The car will be totally different next time out. Much closer to race car spec.

Can't remember if I have posted pics of the old Datsun Sunny race car........ so here you go.

..... and some more.....
Dyno sheet with 400hp is without the 36mm restrictor, but same engine.

So, my plan with the brake upgrade was to run the Alpha Omega kit both front & back. After bolting the EVO 10 rotor on however, the rotor sits a long way out from the strut. In fact, I believe we can get the rotor back at least 20mm and still not foul on the lower control arm. So now the search is on through the dba catalogue for a possible replacement rotor....... stay tuned.
(Pic attached of EVO 10 rotor bolted on with dust shield removed..... heaps of space - Apologies for crap quality photo)

The Alpha gear looks great, I'm concerned though with the EVO 10 Rotor. I'm already pushing the limit to put the 9" rim under the standard front guard. Ive read the +22 offset Enkei will hit the calliper. There is room to move the rotor back 20mm, which will hopefully give me enough clearance between calliper & spokes of the wheel. Some testing to be done to check, but if that's the case I will have some custom aluminium rotor hats made up to fit some Alcon rotors and then have some custom dog bones made to mount the callipers. Nothing is ever easy!
I may well run the rear Alpha kit with the 350mm 370Z rotor..... but I'll take a closer look at that once I get the front figured out.

Will let you know.

Depends on what caliper you're using, 17x9 +22 rpf1 will clear gtr brembos but not evo brembos as they are physically bigger
You might need big brake clearance wheels (something like lmgt4 or te37s)
17" te37 with f40 brembo and 355mm rotors which i believe is the same size as evo x rotors
