Yes I did run a 12.9 at the track recently on shitty tires but I am trapping 115-116mph on every run about 8mph faster than him. And yes I would agree with you that my car is faster.Originally Posted by estis fatuus

when will you have the 240 out again?
Wait a minute, he ran a 12.9 because "HE BOGGED." He would have ran a 6.5 at 13453mph if he used his 2step and launched good.
TRUE STORY!!!! HA HA!
there was probably a deer on the track too, so he had to slow down to avoid it.
all i got to say is, Jeremy won that race. His car is fast.
this is funny stuff..
jeremy would be rich if he had raced the EVO for a Grand all those times
13.01 @ 108.2 with a 1.8 60' was what my STi ran at commerce, craaaaaazy
i've yet to see what id run with 1.5 60's

When did you run the sti?
Evo SE For sale!
Evo GSR Fpred (sold)
WRX (sold)12.8@104
The car should be running right before the new year. I have a few new toys I am trying to throw on. When are u gonna get started on your 240.
Once my G is sold I'll start on my 240, if it doesnt sell soon though I'll probably keep it and turn up the boost.
build... and + boost.. hehe

yeah, you should really build on your g, the amount of tricks and things with 240s is getting old.
but vq tuning is still needing to go much further, you should really try to get your vq to the 500hp peak i have yet to see.
i really think your g35 should be kept and built up further, i read the sleaves are very thin in the vq,
you should get better sleaves. then you might be able to boost at levels as high as 20 psi 25 psi or more and with that you will probably brake the 550hp - 600hp peak.
that will be an awsome g35 and vq (magazine cover time)
Thanks, I'm seriously considering it. There are a few people hitting around 570whp with forged internals, the shop that would do my build is pushing 621whp on their Z with basically forged rods and pistons. If I did it I'd probably just shoot for 550whp and be happy with that. The VQ is relatively new so everything is still day to day, just last week someone anounced they are pushing 550whp on the stock engine and its still running strong with a good tune.
which shop did the 621whp? please not Z1
is that on race gas?
How much boost is on that setup?
boost on the 550hp set up you want?
Nah Z1... I wont even comment but the shop is CP Race in Charlotte, NC. www.cprace.com. The Z did 621whp/604trq at 16.5psi of boost pressure with 100 octane fuel, on pump I believe he puts down around 569whp.
heres his post about it on 350zmotoring.com
It was another late night tuning session last night for CP Racing/FI.com last night. Special thanks to Will (UnderPressure) from DynoDynamics for letting me borrow his dyno, as another car was parked on the shop dyno....and nobody felt like unstrapping it.
So Eric and I made about 30 passes on the dyno, dialing in the car for maximum power. The two man tuning arrangement really speeds up the tuning process. One person operates the dyno, and the other person operates the tuning software...both provide feedback...its perfect. Part throttle and lower boost were already dialed in during previous sessions. At times I feel like this car just lives on the dyno, as it's been subjected to over 200 various pulls on the Dyno Dynamics load based dyno.
From previous tuning sessions, and tuning Gman's car, the VQ with a free flowing exhuast can make about 550whp on pump gas at 12-13psi of boost pressure with a good safe tune. On my car, we've made 573whp on pump gas at 14psi of boost pressure.
But tonight was going to be special...no more games...no more experimenting with the limits of 93 octane fuel. So we increased the fuel pressure to 60 psi of differential pressure (vaccum line disconnected), then reconnected the vaccum line. We then proceeded to add a few gallons of C116 race fuel, for a net octane of about 100 (r+m/2) as the tank was roughly 1/3 full prior to introducing the race fuel. With some final EU tweaking, we were ready to make the pass.
The net result was 621whp/604trq at 16.5psi of boost pressure and 100 octane fuel.
Summary of engine modifications:
1) Arias 9.0:1 Pistons
2) Pauter ORds
3) JWT Cams/springs
4) Mildly Ported Heads
5) ATS Twin Disc Carbon (finally started slipping at these power levels...time for a triple or a heavier preassure plate)
6) AAM Spec Return Fuel System and Walbro 255
7) 550cc injectors (pushed beyond their limits....need to upgrade to 650cc)
8) 100 octane fuel
9) 16.5psi Boost Pressure
10) Greddy TT kit
11) eManage Ultimate ECU
After dyno tuning, we gave the car a thorough flogging on the street, monitoring all of the engine vitals. 3rd gear, 4th gear, and 5th gear pulls were all very impressive. 130mph comes up so quickly, and the car losses traction until about 95mph or so. Just nutty! Coolant temps never exceeded 205F and usually hovered in the 190-195 range.
One problem we encountered was an erratic boost controller...making it nearly impossible to dial in a perfect AF ratio....very close....but I think its time for an HKS EVC boost controller. It has a dedicated CPU for the stepper motor, and is extremely responsive and more stable than a traditional solenoid style boost controller.

So judging by this, i guessing 12-13 is the treshhold on stock compression and internals.
And the head was ported so their z was boosting higher than 16.5 psi.

what's differential pressure?
i mean, isn't this still the add 1 psi of fuel for every psi of air principle?
Nah the guy he's talking about has a built motor and a 9.1 compression ratio I believe. Stock can handle about 12-13psi though from what I've seen. The rest of it you would have to ask him, he's a true expert while I'm still learning myself
Hope to see the G, if you go ahead with that build.
