First go at Santa Pod in my Spec C.
Had a little fun at the pod earlier today , first time in my spec c.
Best time was 12.47 at 108 mph. 60 FT time was 1.78.
Mods are exhaust, remap and air filter and running around 360 bhp.
Full tank of fuel and launching just over 4k. - probably could launch a bit harder?
I think with a bit more practice and faster gear changes this will be beaten but for now Im pleased with that time.

I have been at the Pod a few times so i know what's involved. 
I've had a look at some of the 1/4mile calculators and ones i've looked at calculate low 12's so maybe the OP has a little bit more to shave of his times but i do concede to the general concensus that his time was good.
Perhaps I was being a bit over optimistic but i reckon with launch control and a very quick gear change the OP will make super low 12's. Tyre pressures will play a lot into the equation so there probably is more to come.
I've always run higher pressures than normal so the car would see less rolling resistence once moving because with the 4WD traction you get a better launch and you don't need softer tyre pressures like you might do with a RWD or FWD car.

The tyres pressures were just as normal so maybe I could mess about with that abit.
Ive also just realised I was changing gear maybe too early ? as Id set the rev warning light/bleeper thing at 6800.
If Id changed at 7.5k-8k I might not have needed to change up into 5th gear just before the line and Im sure this would have saved some time.
It does feel a bit worrying reving a subaru to 8k , not sure how risky it is on these cars?

High revs is the No2 subaru killer next to det and you can get det at any rpm although high revs and det together will make a rather exciting and loud bang.
Even with the Spec C i would lower the rpm. You're always better to short shift just to keep the turbo in the sweet spot, that way you're always in and around the peak torque and power band, accelerating strongly all the time.
Revving to 8Krpm makes no sense when the turbo already ran out of puff 1000-1500rpm ago. All you need is launch control to get you off the line quickly and cleanly without bogging down or too much wheelspin, then some well judged, positive, smooth and quick gearchanging should see better times.
Getting your technique sorted coupled with consistent launching should see those times come down. Also I strip the car out of as much as i can before a trip to the pod as i'm such a fat b'stard, and it seems a bit unfair to ask the car for so much without giving it a fighting chance of delivering the goods.
You must have taken your car to over 8000rpm on the rev counter without hitting the limiter to get that 108mph because my gear calculator tells me 7650rpm to see 108.31mph. I wouldn't want to do that too often

I m fairly sure I didnt take it over 7k when at 108mph
, I know it was nowhere near 8. Anyway its a good starting point , pleased with the time and with a bit more practice should improve.

If you were in 4th gear when you did that 108mph you would have been doing 7650rpm. It would have showed more on the clock as the rev counters usually over read by 200-300rpm. I've seen some over read by 500rpm.
Actually you have a JDM box which means the gears are a tad shorter than UK cars so are you sure you weren't in 5th gear? In 4th you would definately have been doing very close to 8000rpm.

Mifo,
108mph in 4th is a tad over 7600rpm on your JDM box (as already said). 1st to 4th are the same in your box than any other 6sp of the same year, but 5th and 6th are shorter.
IMO you don't need launch control..... your 60ft times prove that. I was getting 1.6's to 60ft at your modification level and I never used LC either. With a bit more practice and tyre pressure adjustment you should be able to consistently achieve 1.6's to 60ft.
I would agree with what has been said about short shifting though... leaving 4th gear aside (you may as well rev out in that gear with the power you have, iirc I used to go over the line on the limiter). Peak power of your set-up will be circa 6500-7000rpm. No real point in reving much beyond that point when shifting to next gear.
Have fun as you can try different methods. Take your tyre pressures down to about 10psi and see how you get on.

Same tim,e more or less, as my 12.51@110 in my 340bhp Spec C. I found changing to 5th before the line was slower so I just hung onto 4th.
