You can run a very efficient turbo for your combination with nitrous in the picture. Run a large exhaust housing too, to let the engine breath.

Having a lot of safeties with the nitrous system is very important. I only use it to spool the 91mm turbo with my 224 cubic inch motor. Takes about 1.7 seconds to get up to launch rpm and boost. After the launch, it's all turbo. Saves a lot on the cost of nitrous when you only use a small amount, and small time on the system to spool with.
When I was running the T76, it only took .4 of a second with a much smaller shot (200). The bottle lasted for a long time. 10 passes per bottle, if I remember right. Now with the 91mm, using a 364 shot to spool it in 1.7 seconds, I get 5 passes per bottle.

Nitrous is great stuff. Just try to think of all the scenarios that could get you in trouble and use as many safeties as possible with the stuff.

Of all the systems on my car, the nitrous system has given me no problems what so ever. Just take your time learning the stuff.

I told Goat (Billy) to send you a PM Donnie. He's my nephew and I want to make sure he doesn't blow his dads car up. Kinda important to keep it alive to me and him.:smile: If nothing else than the memories. Thanks.:cool:
 
goat,you got it all wrong.with the 49 the advantage is getting out in front;)i would really question the need or realibilty with a 100 shot on the 49.i ran a garret.63 and a 35 shot which ended up being faster than a pte.63 and a 50 shot.both combo's were monsters on the street with an aggressive gear,pump gas alky, and i left anything sitting from a dead stop,a flat punch would go 1.5 60fts on the track or street and trap over 120+mph. eventually i lost 2 pistons on the stock motor and my current billet wheel strim turbo,heads, cam,ptc combo on low boost and timing has gone slightly faster and got me early departure from 3 different tracks in the few passes i had.the bottle is cheaper to go fast and work but if you break its alot more coin long term.
 
One other thing is breakage on these cars is today more costly than yesterday. Replacement parts are harder to source.. Example find a std/std turbo crank? So limiting possible problems is the way to go.

Nitrous works. It also causes tons of damage when the user is distracted and not 110% paying attention.

20 years ago and parts where plentiful/cheap... was a different story.
 
A few years ago I put a bung in the up pipe a couple inches in front of the alky nozzle and ran a nitrous only fogger nozzle. I only had EGT and Direct Scan and got lucky I didn't hurt anything. NOS told me the jet I used should be around 40 HP. It added about 4 psi of boost. I was running 25 psi total and ran 11.70's @ 115 with it and 11.40's @ 120 with it.

But it was a small shot, but still scared me lol.

Good Luck
 
Yep, Nitrous is like a really Hot Hooker, You want to HIT it but your afraid of the outcome.
 
Im going to do head porting, cam, headers, and some good tuning on it to see what I can get out of that.
 
NITROUS is good.... Great Advice from RAZOR (Julio) and the Resident Mad Scientist (AKA Don Wang) should be heeded. 25/50/75 Max shot to spoil the turbo is not a bad combo. Most NOS guys love to SPRAY 175-400hp... enough to put a Horse down. Turbo cars love NOS for its cooling effect. The SUPRA guy swear by it (Please do not FLAME ME). They actually spray of the line... but the shut it off at a point. Even the import guy spray under a 100hp. (Please do not FLAME me twice). On a HOTAIR, a 50hp shot is worth close to 80-100hp because of the cooling effect... As JULIO said, you really have to be on top of your GAME... The fuel must be on point... or you will get plenty of experience changing Head Gaskets. My HA dyno @ 292hp with just a KB Nitrous chip, K&N Filter, Bosch pump (hot wired), crushed 2 3/4 downpipe and some old Green top injectors on a stock motor. I ran low 12's @110mph with against intercooled cars in 1988/89. The only reason I did not go any faster is my 85 T Type tranny was starting to slip (stock tranny with shift kit). Heck on NOS, I pulled the driver's front wheels 3 inches of the ground on launch....:cool: I cut my teeth on a 83 T Type... My friend and I had a mid 11 sec CARBED/NOS T Type in 1988. We contacted HOT ROD about our car and they were not interested in old technology.... 86/87 were running mid 11-10 sec. CAR CRAFT showed some interest.... We were using a very crude hobbs switch (HELL, I think it was actually drink machine soloniods) water injection with a Holley Carb and a regulated Holley Blue pump. We did spray 150hp... this actually start out around 75 hp. The heads were HA ported and the 4.1 intake was ported and modded for a Holley double pumper carb. On the tranny side, a Turbo 400 w/2800 stall and 3.42 welded rear end... YES.. I did say WELDED..... This car was a sleeper... When asked what year was the car and you told them a 83 T Type... They got owned....:mad: We made more money street racing/grudge racing then we actually did on our 9-5 jobs.....

But life is funny.... marriage and kids took over....

We actually have been following WARWAGON and CHARLIEF1. We are considering building a 4.5 Busch North Nascar engine and putting it into my friend's brother's 260z... This time we will be setting up like WARWAGON and twin turbo charging with possible 3 STAGES of NOS (75, 100, 150), all behind a Turbo 400 w/trans brake.... This time we will use SPOOLed 3.23/3.42. We will at some point contact RAZOR (Julio) about sequential spraying alky:eek:and NOS:eek::eek:

With todays technology, we will be documenting the entire process....

Stay tuned...
