~450rwh for daily driver should not be a problem. With the required fuel and tunning even a T62-1 will do the job...with a Greddy T78, T-66 and KKK stage2 will also get you there at less boost. There's also others but you're gaining lag and giving up midrange power such as a T-88, simply too big.
As far as running over 15psi on pump gas is all about tunning! I could run as high as 18-20psi depending on inlet temps on 93 octane without worrying. I keep it richer on higher boost levels (no higher then 11.5:1) and always keep on eye on my EGTs.
Ernie: Come on....11.22 @ 13 psi !!!! then all you have to do is raise the boost to 15 and you'll be in the 10's !!!!
11.22 and your 122 mph suggest your making over 400rwh assuming your car weights in 2900 with you in it !
I know the KKK is running good for you, even though your dyno numbers were uncorrected but over 400rwh at 13psi !!!!!
Waht does your car weigh with you in it?
See you at the track soon

Not sure if you guys in he US have the Garrett range of TA45 turbos. These are the next generation of T04s, newer blade designs and flow rates from similar size blades. They do not have a BB centre.
The turbo I am running is a TA45 variant and has a .84 front with a 68mm blade, and the exhaust was a 1.22 housing with a 73mm blade. I now have a 68mm exhaust blade wit ha 1.05 housing, but because of rain, I can't tell you what it feels like just yet
My car made over 500rwhp on 22psi and 98 octane pump fuel. Mixtures were fairly rich and HITman says we could have got well over 500 with pump gas, but putting the engine at risk. If it made 500 on pump fuel and 22psi, I can't wait to put C16 and up it to 25psi and timing to match!!

Zro Piston,
I got the kit from Ray when he had it for sale at $3999 (stage2) which is still a little high, but I wanted to try something different than everybody else and it seems to have paid off. It is very streetable. Full boost coming on by around 3600-3800rpms....The kit came w/ everything needed:
cast divided manifold
HKS 50mm wastegate
downpipe
dump tube
block off plates
braided oil lines
etc......you get the picture....
With me in the car, it weighed 2880lbs....
As far as power, Im tuning for 17-18lbs of boost in a couple of weeks before I head to MADS so stay tuned.

I don't understand. 400rwhp @ 13psi. Is that notrous assisted? (Dave said he hasn't seen over 368hp on the ported motor and twin setup)Where is the magic coming from? Even a ported motor wouldn't throw an FD 11.2 range on the 1320. On the twin turbo set up? Please explain...

Anthony(silver FD) from the T&R camp menaged to run 11.1 on stock turbos (non-seq), ported motor and Pettit "unlimited" ECU.....quite impressive!!! on the dyno he ripped 395(?) rwh with same setup...also witnessed that myself. Obviously those tiny turbos were screaming to ~19-20 and back down to 17-18psi !!!!!
I'm sorry Gordon....didn't realize you were in the car when he ran that 11.22 pass <kiddin>
regardless....Ernie has one awesome looking car and I'm sure he'll run 10s and hopefully I'll be there to witness it and shake his hand.

Hey Gordon, didn't realize Ernie had that many dyno pulls under his belt.
I just remembered the motor letting after few passes with the KKK, never dynoing it at higher boost...or has he dynoed it lately with the KKK?
Ignition maps on the PowerFC climb high with a street ported motor past 14 psi...that's were many get into trouble with detonation.

Wow so many kits to choose from and so little time! Those GT35/40's seem mighty impressive as well as the KKK Stage2, but isn't it all of our goals to make the most power for the most applications with the least amount of lag? Well it's mine at least . Anywho, good luck to you all taking the single route. I'm still deciding myself right now and this thread might help me make my decesion.
Was wondering, but what line of the GT's would you guys suggest would be best for overall twisties and straight line? Ball bearings fo life!

Well...500rwh and "no" turbo lag simply don't go together at all 
If you have a 500rhp set up (regardless of turbo) there will always be some lag, unless you have Nitrous assisting with spooling.
On the street I drive on BF drags at all times and even with ~450rwh(~16-17psi) I know when to lift before trouble starts
hp on a turbo car is very controllable unless your gas pedal is stuck to the botton
Later,
John D

A .81 rear, unless on a 4 inch exhaust blade, would have trouble making 500rwhp reliably. It might make it, but would be under MASSIVE amounts of stress.

Try the T04R or the T-78 the T-66 will work as well... The T-66 is most efficient at 20+ psi anywayz. You will just have to build your motor to handle it.

Well, Gordon, I did say that I would dial down the boost for normal driving! Don't worry, I'm not too crazy. I'd lower the boost to where I've got about 425 at the wheels (as stated earlier in the post). Just if a Viper or Porsche pulls up next to me at a redlight, I want to be able to turn up the boost so that I'm making around 500 rwhp so I can show them the fury of Dr. Wankel! But I'd keep it dialed down most of the time. BTW, I'll be using the Apexi AVC-R boost controller because it has gear-selectable boost levels, so I don't go all squirly like! As soon as I put a "new" (new to me) motor in my car, I'll begin construction on the motor that's in my car now (stock internally). I plan to build a beast that can handle 500+ hp. Anyways, just wanted to clear that up!

...Also, what about the HKS T-51 Kai ball bearing?? Would it outperform the HKS/Garret GT3540?? I've heard many good things about the T-51, and this one is ball bearing, so lag would be less. But how do the two turbos compare? Thanks again!
