Your going to need at least 2800 rpm on the foot brake to spool that. I can make 4 psi at 2400, but I have the 6262, and a smaller turbine housing. With "anti-lag" timing, big booster, booster vacuum pump and 2800 on the two step I can make about 8 psi, but that is on a 3250 converter and 11.25" brakes. You said you run street tires, so spooling on the line might not be the best idea anyway, although 13 psi hitting after launch might unload the suspension and blow the tires off as well. I think your going to have to try it at the track and see what works and what doesn't.

NOW you tell me....LOL
I could have purchased and installed when everything was out of the car and been running 10's.....
I totally missed the ball on the supporting transmission mods.
You get those replaced I am guessing since u r tuning on the car...
This is the Shield I'm talking about. I can see a bolt easily getting lodged into the space in this pic. However, I really better get it checked out and stop trippin.
Yes those r the bolts I am talking about..I would check to.see if those r missing before I drove the car anymore. I dont see that size of bokts just getting stuck in the area they where in. Looks like they slowly backed out and then got wedged in. If they r the bolts that hold the bearing in that means u only have one left in there..
Bolts that hold the backing plate on also hold the hub on. I would pull the rotors and make sure that there are 3 bolts holding each bearing on. It would be pretty hard to have another bolt fall in there.

What size are those bearing bolts, if I do need to replace them? The ones I recovered are two different sizes.

Not sure if you had this answered, but as far as I'm concerned, it's a big job. Gotta drop the cradle and pull the engine/transmission apart to replace it.
Stay away from bigger converters... The RPM is not going to help spool nearly as much as brakes, antilag, better fuel, fixing whatever is wrong with your tuning?... and a bigger converter will for sure make you slower and rob horsepower.

Thx, Got Some good News and some Bad.........
Good News is that I am probably going to get a ZZP 3K stall converted installed for Free.....
Bad news is the Head gaskets DID NOT seal...(Damn Cosmetic gaskets )
I will be returning the car soon to get the head gaskets replaced. Going to use Stockers this time... (Damn Cosmetic gaskets )
So the bad news brings some good news.
You NEED a high stall Torque Converter to spool up a traditional big azz Turbo, unless you have a VG Turbo or some fancy exhaust spooling thingie.
Also, what is it with these 3800's and leaky headgaskets? Sorry to hear it bro! Are you running ARP head studs as well? If so what was your final TQ spec? Dumbass aka Dean set mine to 85. I'd have to look thru my texts to verify.

Spool valves are snake oil in my opinion... Just an added complication/danger and I have never known a legitimate race shop to ever run one of them. They really do not make any sense as to why they would even work.
A shop that I hang around tried using one on a supra and it just reduced peak power with no 'spool' increase.

User error... Mine work fine.

I have a question for nosrac or whoever else has some input. On your upper intake do you have all the pcv parts inside there or do you have just the filter on top. And the hose coming off the factory pcv spot are you using this for your fuel pressure regulator. I'm running the same intake intake. I'm running into the problem of oil blowing out of the back valve cover.so I want to try your setup. If you could give me little info your pvc and vacuum hose routing that would be great.

I have filter on top and in valve cover. The hose off original MAP port goes to MAP and FPR.
The original brake booster port is going to brake booster and the evap port next to throttle body has been tapped for the BOV.
Thanks for the info. Im gonna assume you dont have a pcv valve in there or that tube. It has been awhile since I worked on my car, but if I remember right there is two little holes in spot where the pcv valve sits. Did you leave both of those open. Thanks again for info. Awesome looking engine and install.

I run a PCV valve, and a breather on the valve cover. Port on top of intake is plugged. I'm running a 2 bar map sensor that fits in the stock L36/L26 location. Below the PCV valve I put a transmission check ball, it moves and allows PCV to evacuate the crank case under vacuum, but any boost that leaks through the PCV is blocked by the steel ball when it drops back onto the PCV port in the lower intake. Seems to work well, no condensation in oil and no oil from breather under boost.
I still use the factory pcv valve but get the fresh air draw from the valve cover. I've boost leak checked it several times. All seems good and no moisture build up anywhere.
Hey thanks alot guys for all the info. I should have asked back in June. I would have had a chance to take it to the drag strip then. Whats everybody using for a fuel pump. I have a walbro and getting on it just for a few seconds, it doesnt do very good. One guy told me to try a adjustable fuel pressure regulator, anybody using one.Sorry to ask questions in your thread nosrac, but it is a really good thread with some very helpful people following it.
I'm using aeromotive stealth 340, but have heard good things about the deatschwerx pump. My walbro barely kept up with my supercharged setup, no way it will feed a decent turbo setup.

Did you do a fuel pump rewire? The pumps work a hell of a lot better with the added voltage.
I am running the Aeromotive 300. Great pump, I cant even hear it running. One thing I did notice is that If I drive the car for any distance, the brake pedal will go to the floor. You guys running a decent cam have the same problem? I have the ST2 ZZP cam.

That makes zero sense. Lack of vacuum will create a hard pedal.

I really haven't driven mine much with all the issues but great vacuum and brakes especially after redoing my lines with actual vac lines instead of fuel lines. BTW I have ST3 cam...to tune it you just have to raise the idle
