Hoosier drag radials. I had to tweak my rear camber because the sidewalls were rubbing on my coilovers so the rear is out of wack currently.

28psi tapering to 26psi. I didn't have any timing in it either since it was the first run on the motor and I wanted to do a shake down pass first. Not to mention I only have 300 miles on the motor

Glad I could film ya, Jeff.

On the way to the track I witnessed a Semi on the freeway almost flip with a strong gust... his back end started to kick out and tires were smoking, but he hung on to it.

And somehow I got in for free, haha...

Corny, but fitting for your login Jeff. Congrats on getting it going and good pass too. I don't know how much the wind affects it, but has to be quite a bit.

Makes me excited for my EFR build that is 1/4 of the way complete right now!!

Put in some nitrous Jeff just a 70 shot on same boost, the new year is gonna come and we need to see that car deep in the 9s!! I am sure you can tune nos and turbo on e85 and show why a sleeved block is not needed!!

Or you can try 35 psis and see what`s capable on boost only... Good luck man.. car is running strong!

Lol, I would never run nitrous on stock sleeves. If I had a sleeved block I would probably try a 50 shot.

The car went 6.3@110 in the eighth at 32psi before it broke a valve seat and it still went 10.3@108 at that. With that 1/8th mile, it definitely has around a 9.7 as is on only boost which I intend to reach. Just need the weather to cooperate. Believe it or not, my car actually runs/hooks much better when it is hot out

Keep in mind I am still on the stock 05 tranny. If I went to an 07 tranny or rallispec gears, I would pick up around 5-6mph off the bat and .3-.5 seconds as well not having to go into 5th .

Exactly... I hate watching you hit that wall that is 5th gear. I see slower ET's in '07s, but higher traps... grrr.

Maybe we learn how to install '07 gears....

the rallispec gear set is tempting against the 7 sti, I have used it on a 05 sti build and made 10.8s easily on our slow/heavy track

not tempting... it's recommended! Hold 4th gear to 9000rpms!

What about running a taller tire? Would that help hold out going into 5th? Should help with traction anyways.

Isn't high compression going to raise back pressure unless you run a larger turbo?

diesels run high compression and usually make loads more torque than horsepower...

Yes, you are right but for completely different reasons.

Late 70's big block v8s run low compression and make loads more torque than horsepower. Maybe we should all lower our compression ratios to make more torque. Just run some deck plates under the heads and kill the autocross course with all those torques!

Ok, to not be so sarcastic and even ignoring combustion, power is a function of torque and RPM. Note the operating speeds of auto ignition engines (diesels) and 70's big blocks and then that of a modern performance gas engine. You'll notice that Hp and ft-lb always cross at 5252 rpm (won't get into the explanation) but that below 5252 rpm, torque will be greater than power and vise versa.

So if the engine never revs beyond that speed (in units of HP and lb-ft), it is impossible to have more power than torque.

I have looked into building a high cr on my 2010 wrx but decided not to.. but as to your worry about the 80-100whp diff this is do to your change in cr. Im sure if you compare both graphs you will notice that you have more gain in the low and mid range where as you lost on the top. I did not catch what turbo you are running. A high cr ratio build is not for top end power in the ej series motors.
