My setup + juice. Input needed!

[91CoupeMike]

If you have sigs turned off, it's Brodix st 5.0r heads, systemax intake and a 218/228 510/510 112 Anderson cam, with stock 302 short block. It currently makes 320whp 315wtrq n/a and best of 7.6 at 90.8 mph.

I wanting to put my nitrous kit back on it, only ran a 125 when it had stock heads/cam/intake. It was a fogger nozzle in the intake pipe. It ran good but I melted a plug on my 2nd bottle, figured it was caused by the fuel and air mixing in the odd shaped intake.

So I have a hookup on getting a nitrous express plate for the systemax and was wanting to know if that is the way to go, I'll be using the zex box with the built I wot swtich.

I was thinking a 100 shot would be safe, how much more can I put to it before it gets in the May pop grey area?

Thoughts? That should get me in the 6s right?

Stock blocks spilt around 450 if I remember correctly

[War Machine]

100 shot are for fags and 4 cylinders!!

I've seen people with boosted applications (turbo) run 500-550, but I figure the nitrous will hit it harder then boost rolling in.

I'd be close to 450 with a 100-125 pill.

It's a wet shot, I only have 24#s and a Holley 255 fuel pump, is enough to run a dry shot, or wet shot even?

I agree, if it lasts I may ramp it up... But at 208k miles it should make for a good time.

Nitrous causes an instantaneous spike in torque which does all kinds of neat things, such as distort the crank in the block. Turbochargers have a ramp-up on torque because of the built-in power lag: nitrous lacks that

So 100-125 is going to be the most I want to use? I know I'm taking a risk but what the hell...

I'm going to take it apart and make for sure I don't have any cracks or anything before I put the bottle on it again.

If I can get it to trap 100+ in the 8th I'll be happy.

70 dry or 125 wet would be a nice place to start. Like anything else performance minded, it's has a lot to do with the tune up. EFI intakes don't flow fuel through the runners efficiently so a plate between the upper and lower intake remedy a lot of under/over fueling. The dry shot only has nitrous going through the intake so puddling isn't an issue. The timing in your tune would be the only real concern if you start upping the shot, you need to see what the total advance is and either have the appropriate timing pulled or retard your base timing to go with the amount of nitrous added.

Sct switch with different tunes is the plan for solving that issue.

I can get a new nx plate for $325, do I have enough injector to run 450whp? Because I can just get a dry nozzle and get larger injectors for about the same costs. Given my setup which is easier / better to use dry or wet?

Would a main girdle be worth the money?

[Sleeper]

Itll be fine. Even with 24s but id step up to 30s.

Heads and cam n2o combos where a dime a dozen back in the day.

I know it's nothing new, just want to take advantage of any new technology and knowledge you guys may have.

I of course want it to run good too, I see to many people with built cars that run like a 2 legged dog.

Ive had people argue with me, but I feel like there is a large difference between 500hp at 6k and 500hp at 7500. These engines vibrate quite a bit, I think that is where the cracking is coming from. I've never cracked a block, but have run a 300 shot on a hci 302. Either way, its all borrowed time at those numbers.

All a girdle will do is hold the motor together a little better when it pops. I ran them just because.

That's my view on them too, just never had any hands on with them.
