    question for the pros>

    hi im fairly new to this forum. i have a venom recluse 400 nitrous system and am currently running a 65 shot. what i was wondering is that i am planning on getting a TRD sc/er for 1800 pretty soon. i was wondering how bad would it be to run a 30 shot with the supercharger? i mean its a week shot, but would that be too much strain on the engine?


    BTW stock internals

    why do you even bother to spray 65 on a street car?

    Hey Rolla Mustange Killer,

    Vortex has a point: it seems that the most basic way of determining engine integrity is by the amount of horsepower it's putting out. Case in point: The guys at http://www.importperformanceparts.net/ say you can run up to 200 hp on stock connecting rods. In other words, instead of saying, "You can run this much boost" or, "You can combine this much shot of nitrous with this much compression" it's easier to say: your stock engine can handle this much horsepower. By the way, it seems from what import performance parts is saying, your con-rods might be the first limit on how much you can pump out. So, supposedly, you could get your supercharger having the car put out 166 hp, and then you could tune your nitrous to bump it up to 200 hp. By the way, this is partly conjecture on my part, but I'm not sure what you need, or even whether you need, to consider regarding compression and detonation/knocking. Nitrous will cool your boosted intake and might even eliminate the need to even consider lowering your compression? But, if I were you, I would try looking on some more turbo-oriented or drag-oriented forums.

    If you plan on running the SC then it depends solely on how much pressure you'll be outputting from the SC before you go calculating how much Nitrous you will be wanting to run. For example. You say you have stock internals. Well if its possible you may run 10psi (keep in mind i have no clue the output for the SC, I'm a TC man myself) then I'd say running any Nitrous is a chance to blow your motor. I wouldnt honestly be running more than 100hp over stock if you car is 100% stock otherwise if I were you. In MY case, I did all kinds of crazy stuff to push the limits of the corolla motor... why? because I had spares laying around... :)

    slvr2000fdvspec talks a lot of shit since he's a &quot;TRD whore&quot;. apparently that gives him his awesome expertise. thank you vortex/wheee! for thinking it out and helping others.

    Hey Nakinmohoes, I was getting pretty discouraged with some of the trash I got with my "Raising the Redline" thread. Thanks for the moral support.

    oh so you're the authority now huh noobie? <br />
    <br />
    go spend a shitpile money, truly test the limits of your corolla, post a few hundred posts and earn some respect and then you can maybe act like a lil bitch and bust on people and possibly get away with it...<br />
    <br />
    no one asked for your cynical comments

    Then I'll say it... a DRY 65 shot on stock internals, good luck with that in the long run. And you want to run boost on top of it... You will have to strenghen the motor in order to run that combo for a length of time that is worth the investment.

    Who cares about post count. I agree you shouldn't make fun of people as a noob (or a regular member at that), but for your opinion or comments to be meaningless because of it is just ignorant.

    But some people just deserve a little hazing now and then.

    i am an authority on toyotas actually and if u take everything that seriously....just chill out man all i am saying is that if u run nitrous and boost u will probably want to strengthen your internals but if not then please go right ahead and do as u wish it is your vehicle.....and u dont have to spend &quot;shitpile money&quot; to make a corolla fast either its all in what you know so rock on woo yeah i have no idea whats goin on

    never said ya needed to spend a shitpile to make it fast... heh just if you wanted to test all angles and know what each scenario can do. A *few* of us have done different things to these motors and compared notes to come up with the tolerance levels from tests we've done. Between the few of us a ' shitpile ' has been spent, lol.

    To set the record straight... it is *possible* to run a 65 dry shot (if you're compensating your fuel some other way such as eManage or such) however, that high of a dry shot would require you to max out your injectors and would borderline on a detonation. I was thinking a wet shot was what he was referring to - if I was mistaken, then I accept being wrong there. I was working off the assumption he was doing the smart thing and running wet therefore having the extra fuel compensation needed. The internals of the 1ZZ's that some of us have tested have been continuously run with over 100hp extra added to the load. I personally have been (well before some dumbass owned my car by blowing a light this week) running 14-15psi of boost on my rolla (10-11psi @ sea level) and one other here has been able to run near 13-14 for quite some time. (correct me if my figure is wrong sean)

    just sayin we've put practical tests to use on these things and pushed them. My car had over 40K miles on it after I turbo'd it before it was objectively decommisioned this past week. I actually had a chance to take a look at the crank and the inside of the cylinder walls while stripping it down (yeah so i got a lil bored) and everything looks great in there.

    *shrug*

    Also, perhaps I came off a lil harsh in my flame/haze - Ive been in a hell of a lot of pain this week and the combination of the pain and the medication has turned me evil a few times... *some* of the intent of the haze was legit tho, but don't take it too personal.... lol

    he is running a DRY shot (so he says), that's the part that doesn't sit right with me. You would think wet, but no... dry.

    A dry 65 shot will wear a hole in your piston after too long. All you need is a hotspot on the piston, and you'll wear through it pretty fast. Are you running colder plugs? If you run a 35shot+ S/C on a totally stock engine itll be fast for a short amount of time. Running a 50shot just every 2 weeks for timeslips will take a bit of life out of the moving parts of the engine.

    You could get 200hp alot safer out of the S/C with a 9psi pulley, I/E and maybe an eManage if youre still running lean. I know the S/C comes w/ a new ECU so youd have to get a A/F meter to keep an eye on it.

    If youre just looking to blow the engine up(1zz's tend to be cheap anyway) then run dry shots on the S/C after 3000RPM and try for the 12.000 ET. Just be laughing and not crying when your car crosses the 1/4 mi line in flames and smoke...

    He swears im a moron and a dry shot is the way to go because &quot;his friend said so&quot;. Im still waiting for his pics on the nitrous system that he cant seem to get.
