Anyone running nitrous AND turbo? just what the title says. I know everyone is always talking about the spooling benefits of nitrous with turbo applications, I was wondering if any turbo guys were actually doing it. I know alot of the supercharger guys are running nitrous on their setups... just wondering. Also, if you are, post info on both setups, I.E. turbo setup and nitrous setup, and how it's worked for yah. (this could get interesting...) 
i have been spraying for awhile.
first set up was a t76 and a camed 6.0. with that set up it took just a hair longer to spool than i liked so i gave it a small shot to get it spooled up. sometimes i sprayed up top too. i think i was near the limit of the turbo and power came easier with a small shot rather than more boost.
then i got a 408 and it spooled instantly with the t76. no need for a shot out of the hole, i couldn't hit it with full boost out of the hole or i would fry all 4. eventualy i hit the limit of the t76 and had to spray to get more power. a 100shot gave me about 140rwhp(edit 127rwhp) and 200rwtq.
turbos and nitrous go together nicely if you need help spooling or are out of turbo. if you dont need help with either of those things i would just go with more boost and avoid the extra complication.

Armageddon is currently installing an NX single nozzle wet kit i sold him on his 6.0L turbo and he's going to visit Gomer this weekend for some dyno tuning/ numbers. Think he's gonna run a 75shot @ 12-13psi and see how she does.
He'll prolly post in here shortly for the 411 on it.
Was thinking of tryin it w/ a 50 shot on the FMIC whenever Speed Inc does my 6.0L iron block setup just for the cooling effect but i dunno. Cant do it now since my block is pretty much maxed as far as power goes

As usual parish, great info. The main reason I asked was because, like always, everyones always talking about it but nobodys ever actually doing it. It's good to see that it worked out well for you. I have a T70 STS setup with FMIC and the snow injection kit. I also have a NOS direct port setup. Was wondering if I should get rid of the direct port setup, or keep it, and add it to the mix for some interesting results.
What internals do you have on the motor. A DP min shot is 200hp witch by parish is 280hp. That is a lot of power to be spraying into a motor that is already making a good amount of power.

Engine is in the building process... pistons are coated diamond pistons with the 8.6cc reliefs, scat4340 6.125 forged rods, pro-select rings, force fed LQ9 stage 2 heads with the 72cc chambers and patriot gold valve springs. (heads are also getting coated) ARP head and main studs, cam is a comp cams 226/220 564/570, 115lsa. The turbo setup is PUREVIL's old STS setup with the FMIC and the T-70 turbo. Clutch is a SPEC4. Rearend and drivetrain upgrades on the way. Nothing is in the car yet,just getting it all put together and waiting on a few other parts. I got the direct port setup because it was a great deal on an intake and 90mm throttle body with the nasty fuel rails and it came with everything you need to do the whole stand alone fuel system and all for the nitrous. I wasn't originally going to do nitrous, but since I got it sitting there, was just curious. It's plummed for a 180 shot now. I don't think I could plumb it down much more and keep the fuel atomized. thanks for the help guys, keep it coming, this is good ****!!!

I use a .060 nitrous jet with a .032 gas jet in a plate system on top of my intake under the throttlebody. It helps me to get spooled up on the transbrake. I use twin 80mm turbo's. When the nitrous comes on the boost jumps fron 2psi to 15psi instantly then creeps to the two step setting(6500rpm) at 25psi. We tried shutting off the nitrous coming off the brake and it would labor the engine and pull it back to 5500rpm so now we leave it on. This keeps the engine up over 6800 during the run. We have had some trans trouble's but the combo is very good to help spool.

twin 80mm turbos and a nitrous setup?! that's pretty ****** badass!!! If you don't mind me asking, what size shot you putting out on that setup, on top of the twin turbos that your cranking to 25 psi? that's pretty ******* sweet...
I made 624rwhp 678rwtq on pump gas today at the dyno running 13psi on a 70trim... I've got a wet kit I'm running ontop of it... maybe a 75/100 shot. We'll see how that does, maybe a bigger turbo too.
I never used the nitrous on the dyno but it should make 125-175 on the .060 jet. We leave the starting line at 25psi, at the top of first it hits 32psi.

427,
I am very curious about your setup, what all do you have in the engine to get it to handle that power and how much power are you able to squeeze out of the combo? I have seen pics of your car and it is one hell of a machine!

Bryan,
The engine is fitted with a Callies 3.5 crank, Oliver 6.125 rods, Mahle 4.005 pistons in a iron 6.0 block. The car will be in Hot Rod magazine soon with a basic rundown of the engine. There is also a Magazine called Engine Masters that has a more in depth article coming about the engine.
The power was 1697hp @7500 rpm on a engine dyno with 30 psi. On the dyno the turbo's were surging above 7500 rpm so I did not run it higher although it was still picking up power. In the car we are shifting it at 88-8900rpm with the nitrous on and 32psi of boost. I think its making about 1850-1900hp in the car. The head gaskets are leaking on every run a small amount. We have some transducers on the cooling system now to moniter temp and pressure, hopefully this will lead to some improvements in head sealing.
We are planning on running the car at the track again real soon as it has a Bruno/Lenco in it now that should cure our trans issues.
I will be selling this engine in the wintertime if you know of anyone that races with a LSX engine.

WOW, that is one hell of an LS engine, I am curious, what have you done to the bottom end to get it to handle the power, billet caps/girdle? I am also curious about the pistons themselves, any custom work (ring lands etc). I am in the process of putting together a 1000+RWHP combo for the street here in CA and I am doing my homework. Also are the heads o-ringed and are the head studs still stock size or have you enlarged them. I understand if you don't wish to answer but I would love the info.
Thanks,

Bryan,
The engine does have steel caps and a W2W girdle system. The piston is a Mahle custom made for W2W. The headstuds are 1/2. The head gasket is copper with o-ring/reciever groove combo.
