Nitrous + 604 = ?

[Tim_K]

Maybe this is a transmission forum question, but it's also a V6 question.

Who has run nitrous systems on their V6 engines with a 604 automatic transmission? How much HP gain was it, how long was it run for (like how many 10 pound tanks), and how did the 604 handle it?

While daydreaming at work today, I briefly thought about this for my '93 Shadow ES V6 / 604, but don't know what the 604 can handle. I wouldn't think that to go more then 75 hp or so on a 604 would be a good idea.

I think 543 manual gearboxes can handle as much as the engine will, either stock or modified.

I think this is a question best answered by Reaper1. Since his "new" car has all of the above mentioned parts.

If I'm not mistaken, When Rick L owned the car, he was estimated to have 240hp without the giggle gas. And over 400hp with it. However, his A604 isn't actually stock.

The 543/523 guts can probably handle it, but be weary w/o the diff. pins on a more than mild modded engine will yield "boom".

with the right tires u wont peg leg and wont need to worry about diffs going..

Wow, that's nearly a third of a gigglewatt.


okay, for the terminally pedantic 0.298 Gigawatts.

i had some on mine but everytime i used it the tc slipped like hell as did the trans itself. that was on a 70k mile 604

I read the thread title and the first thing that came to mind was "BOOM".

OK..I finally got a chance to go throught the forums completely!

Here are some answers:

How much gain is dependant on how the engine is built and how much of a shot is being run.

Supposedly the 2 10# tanks, running the 150 shot, would last something like 8 passes IIRC. That's not bad really considering how much there is flowing!

As for the tranny, if it's stock and has never been rebuilt...this will definatly make it so you have to get it rebuilt! The converter needs to be upgraded for sure(as previously mentioned). Diff pin savers, or a true limited slip(Quaife or OBX) are HIGHLY reccomended. I'd go looking around the ASOG people for these things.

Finally: a 75 shot isn't actually a lot. A stock engine, if the system is tuned propperly and you have the supporting equipment, should do fine with this. A fogger system is NOT reccomended due to the uneven wet flow characteristics of our intake manifold. Therefore the more expensive direct shot is the way to go. Even though it is somewhat of a small shot, I'd also suggest some sort of management, like a Jacobs Mastermind or the NOS system. It softens the hit to help with traction and parts breakage, and can save your engine!

HTH...

nitrous+ a/604 = transmission fluid shower! if u want it to go out so u have a reason to put in a 5 speed go for it thats what i was thinking about doing

[Reaper1]

Once again...if the transmission has been rebuilt by somebody that knows what the hell they're doing and is built for performance you shouldn't have an issue provided that you use the propper fluid, change it often and don't do stupid stuff with it(and that could be any number of things).

If you want to say negative stuff about the A604, then be my guest, but please be able to back up what you're saying and know about them a little bit...I'm getting SO sick and tired of people just coming out and say "oh, they suck"....yeah, so do Ford C4's until they're built right! So do a majority of American automatic transmissions in one way or another. Do some research, get a little expeience with them besides what your mom's uncle's sister said her friend had happen to her. Then come back with some intelligent feedback.

Thanks!

So, when are you going to be testing the limits of your built A604?

I think I'm going to try putting a stock one to the test here before long.

A604 rebuilt + boost = I guess we'll see!!!!

[Reaper1]

Dunno quite yet. I'm about to graduate with my AA, and I've got my application in to my college of choice. If all goes well, I'll be starting my final road to my 4-year degree in the fall. I may even double major, not sure yet. First thing is I gotta get accepted! At any rate I'm working on things slowly. I'm getting rid of clutter and making room to actually work. I've currently got one project that is definalty ahead of all the others. Then I have my 'Baron and the Daytona.

I've decided to pull the engine on the balck car and tear it down to inspect it. I want to do this for 2 reasons: due to the other things I've seen with the car I don't trust the workmanship of the shop that built the engine, and I have to pull it anyways to get the fuel lines in it! Mostly it's time that it's going to take, but I want to take my time so I do it right! This isn't worth rushing!

Don't you only need 1.2 gigawatts to power the flux capacitor and go back in time? lol

[Reaper1]

^^I think that was supposed to be a different thread...LOL

i have 2 true a/604 stories for you the first is how i bought my 93 daytona es with 60,000 miles for $650 because the tranny was stuck in limp mode and quote "shot" i took it home pulled out the speed sensor and wiped a little bit of metal shavings off it and viola! all 4 gears again with no slipping or anything then 2 years later im going 70 down the highway and the a/604 downshifts itself into 1st gear!!!! my show car did 1 complete 360 on the highway and i almost got hit head on by a semi! so i replaced the speed sensor and the tranny was fine again but that honestly scared the shyt outta me and as soon as i find a 5 speed with all the parts that a/604 is gonna be my new boat anchor. No tranny should even be made possible to shift itself from 4th to 1st going 70 thats auto suicide so think about that little story before you decide to add nitrous to your 3.0/ a/604 is it worth totalling your car and ending up in the hospital?
