U think if i did a dry shot ahead of the maf... It would adjust fuel when spraying?

From what I understand, the TPI computer is to slow to make the needed changes for a dry kit.

I can't speak on this, but it was what I've been told before, I've never had a N20 on a TPI car.

yes on the nitrous....amount is depending on your willingness to push it...75-150hp
NO...on the dry kit, wet plate kit would be best but single/dual nozzle will work

make sure the ignition and fuel systems are up to par, change plugs, retard timing, have some fun

Tpi ran just a basic obd1 ECM didn't they? If it did datamaster should scan it, plus you get 20 free scans before you buy it. I had the ostrich setup and everything on my 4.3 tbi for tuning. Tried using datamaster for scanning but never could get it to work, course when I gutted the dash I found someone had cut the aldl connector wires lol. If you need some info moates.com has tuning stuff for obd1.

What??? Your motor doesn't have ports? How does it run!? Lol sorry couldn't resist.
Should be able to make one. Just get the connector from a salvage yard or something, then if I remember right it'll just need an ignition hot wire, a ground, and then it'll need a diagnostic signal from the ECM. From what you say that will be the hard part cuz you gotta track the wire. A Haynes book would say or if your lucky you can find a pinout for the ECM. Ill do some diggin cuz I know I took notes and archived some info on it when I was rewiring mine.

have your tuner pull *4 timing get a WET kit and spray a 75hp shot and your plenty safe and its enough to put a smile on your face

(and to all the naws pros yeah the rule of thumb is 2* for every 50 shot but if he is wanting to play is on the safe side and not push it more timing pulled then needed is way better than not enough pulled ) with the extra timing pulled you may lose 5-7 hp with out spray but that is no biggie.

75 shot 100shot 125shot would be just about the maximum I would put on there.
There is no special tune to do on that motor to handle nitrous I promise you, many years of nitrous on TPI cars here..
You can pull timing on your own via distributor
I use autolite25 plugs gapped at .035"
Timing set at 6°-8°
No air leaks in the Plenum boots
Of course place the nozzle behind the MAF
Check fuel pressure 44psi w/ vacuum line off
With a 700r4 I prefer to have a manual activation switch so I can deactivate the nitrous just before the the 1-2, 2-3 shift since some 700r4s get pissed and freak out and not shift in time even during the useless manual shift that people tend to do. Right now if the car is in good shape it should be running 14.8 for an '85 so expect to dip into the mid 13s on a 100 shot

Sounds like timing issues. Knock sensors too tight maybe, or your timing is off at all points which is why the slower burn of 112 helps start and also delays the combustion at wot and gets rid of your pinging. Just a thought.

Higher octane = slower burn so its igniting later than it was. If it were me I'd try turning the timing back a degree or two. Should be easy with the distributor. Might wait to burn the 112 out tho. Give you more run time to make sure it wasn't just a coincidence and also avoid having to readjust when you go back to regular pump gas.
Of course for all the work that's gonna take you could drop an LTX in... Lol

LOL.. it may get one, one day.. carb'd though.. nice and simple. The car is a spliced and disgusting assortment of wiring harnesses, that would make an FI LTX even more of a nightmare... but we will cross that bridge later.

Ok..Ill run the fuel out of it first and see how it is runnig till the tank is done. Amazing tha 5 gallons of 112 in a FULL tank of 93, can be noticeable? Hope its not in my head. lol

Ghettogmc23
05-04-2013, 11:21 PM
Well full tank of 93 - 5 gallons of 112 how much does that leave you? Maybe 11? So that's about 33% 112 so your actually running about 100 octane (this is all in my head n I've been awake all day so it might be off lol)
either way if your only a degree or two off that's enough octane boost to handle it. Regular to premium is what 89 to 93? Not saying that it IS the fix but seems like what I'd go with as a plan of attack. Course reading your plugs couldn't hurt. That's how I learned mine had problems with over fueling, the strong smell wasn't enough to tip me off lol

Thanks. I do what I can to help out because I've been in the spot where I didn't really know what to do and I know how nice it is to just have someone to bounce ideas off of. Actually up until about two months ago I didn't really know what BLMs were for, but now I'm pretty confident in how to use them for tuning. I love diagnosing problems, its fun to me cuz if I'm right I feel like I helped and if I'm wrong I usually learn something. I just do a lot of research when I'm bored, that's usually how my projects get started. That's why I'm on here all different times of the day lol.
Keep us posted, I'm interested to see it running good to see how the wet kit does and how you get it set up. That was my next step for my LTX until I had a few hiccups. Plus if you don like it ill buy it at discount from ya lol.

Your right, it is allowing you to run more timing, which is a slightly longer burn so it is more powerful. Sounds almos like it was supposed to have higher octane.
You can leave it and run a mix, it would be like stepping from regular to premium for more timing. No real drawback other than doubling fill-ups, fuel grade quality, etc. you know what's up lol.
Or you could go the other way n run pure 112 n bump timing up a bit lol. Lotta options depending on what you wanna do overall.
Your current setup would probably work well with nitrous cuz if you plan to run at the track or something just fill with pure 112 n timing shouldn't need adjusted, but don't quote me on that! Just in theory sounds good.
Personally I'd just do the adjustment n not keep mixing for the main point of being less hassle in the long run. Idk how much you drive it so maybe once a month to fill up wouldn't be too bad but every week or so might get rather annoying lol.

LOL... thought about making the vette the site car.. but I really do use it to much to make it "everyones"
car.... The camaro used to be a DD till the past year... I just want to keep from beating on it...so that is where the vette comes in. In fact the vette was purchased because driving regular cars bores me.. and while the camaro was down I needed something more enjoyable to drive...

Here's an article from carcraft, not much tech just destruction but gives you a hint at how tough a SBC is.

That's a good article.
Main thing I've learned about hypereutectic pistons is they have a higher silicone content. They're not much weaker than cast but don't hold up to heat as well. So either way your durability would be about the same when it comes to nitrous.
If it was pinging like you said it may have weakened your pistons a bit, a nitrous shot might be enough to break something that's already a little stressed. However with this being your backup backup dd I'd say it'll handle it lol. Just keep it fueled up n keep the timing right, the amount your looking to spray shouldn't have any force like the one in the article lol unless you hit it in low RPMs

I was always under the impression that CAST was fragile.

It is fragile but not all that bad, trust me we were using Nitrous a very long time ago and even before me. Let me see if I can find this old article of a crossfire injection c4 Corvette that runs N2O with NO mods at all....... searching......

Forged > cast > hyhypereutectic
you can run a lot of boost and nitrous on any piston, it's all about avoiding detonation and keeping fuel to it to keep the heat down. All forged will do over cast is put up more of a fight against tuning issues. That article pretty well proves you should be okay. Your pretty well set on running it so may as well just start settin it up lol

Now that the vette is running 100%.... or close to it.

Can I just do a 50 or 75 shot of dry...without adjusting other stuff?

no....but I am sure other will chime in to the contrary.

I would never run nitrous without a way to adjust timing (easy enough on yours), and swapping plugs to a colder heat range. Also for a dry kit you will need to handle the fuel enrichment to compensate how do you plan on controlling that?

Nitrous is not something you just throw on and go....if you don't have a way to accurately control fuel enrichment then dry is not an option

Thats why I ask.

I didnt know if there is a small enough shot that is "throw on and go"

Have a friend with a busa... he hits it with a 40 shot on a weekly basis... dry.

^thats what she said! i wouldnt ever run dry, i had a buddy with a built c5 vette doing a big dry shot and he blew up his intake mani when his controller bugged one time

I've never ran it before but SexyTransAm is pretty nitrous-literate. Maybe he can chime in on the dry shot. A 50hp dry shot just to get the system in and play with doesn't seem like it would hurt as long as the fuel system has enough capacity.

Im always lookig to learn. Id just love to see my vette hit the 13s now that its running right. Im thinkin a small shot and gears will get it there. it did like 14.8 huffing fuel out of the exhaust.

A 50 hit will be just fine on stock plugs and timing, I hit my car stock with a 125 wet and just changed plugs and never got any detonation . But u will need to make sure the fuel can keep up with that dry shot. Most dry kits do that by jackin up fuel psi.
