You would have to drive across country in 3rd
Okay, keepin the converter where its at.

Good idea man, you just saved your new tranny from a sudden death!

At this point in time, my only adivice to you, get lots of small parts boxes, keep all your bolts organized and labled, Morty, this is crucial, and will save you alot of grief. Take pictures, lots, not necessarily to post on the site, but for your own reference, trust me, It gets a bit complicated once u start un hooking and removing wires, plugs and vacuum lines. Don't try to beat the clock here at all, take your time, I did to an extent, and Im fairly pleased with the results, however, It has cost me alot of money now as I am seeing what my cars' breaking point is. For god sake, make it so that car can make it to WCBF this year!

I'll be there, don't worry . I'm doing things in stages... while the tranny'* being tranified, I'm going to be doing all the porting. Before I put the top end back on, I'll switch in the heads. Et cetera.

And I repeat...
I totally disagree with you on the tuning thing. Maybe their is no tuning on a setup like yours where basically you are just misting water into the intake. But if you want to get the most out of W/I the tune is going to be crazy!
I really don't get why you would run water injection and not look to get the full potential out of it. It just seems like a waste then to me.

Saying you have to port a SC to run WI is asinine. But you're the expert.
And I quote...

"Saying you have to port a SC to run WI is asinine." You said it not me! It looks like you said that you need a ported */c to not make the engine work efficiently but W/I work efficiently. I know what your getting at it just wasn't worded the best...

If you are adding a form of gas to your intake stream that is unmetered by the car, how do you figure your not going to have to tune?

WI isn't something new and mystical. It'* been used since 1910 in cars and was used extensively in WWII in our aircraft.

But you're the expert. Maybe I'll ditch my system since you know so much about it. You learned all this by doing it YOURSELF like I did, right?
Thanks for the history lesson. Quote me where I say that W/I wouldn't work or doesn't work? All I'm saying is that N20 will cool the 'top half' of the motor better then W/I. N20 will give you more power then W/I would. N20 is going to be safer then W/I unless you are only using W/I to mist the intake.

Where are you getting this info? You have O/D with a higher stall converter, the only way you wouldn't is if you get a all out race converter that has had the lock-up clutch removed . How many 4T65e are out their with higher stalls? I don't see them failing left and right...

I wouldn't recommend a crazy stall but in the 2500-3000 area.

We're speaking from OUR experiences with these things. And I don't have a habit of intentionall steering people wrong on some of these things. I wanted to KNOW about water injection. I could have purchased an off-the-shelf solution and plugged it in. I chose to develop my own from scratch and actually learn something. I'm on my 4th home-built system now, and to this day, I've only got ONE component in my system that was made by a water injection system manufacturer. The nozzle itself. I MADE the nozzles in my previous 3 systems.

I try MANY things on my own car. Simply to see what works and what doesn't. I post my successes for others to try.
That just shows how much you know about me ... I did run W/I over the spring/summer... I didn't care for it - O2'* were all aver the place, once I thought that I got them locked in temps/weather would change and I was at square one again. I was constantly scanning and logging. I finally gave up with it b/c I didn't think that what I was getting out of it was worth the pain in the *** it was.

If my tranny ever goes you bet your *** I'm going to be putting in a higher stall and a gear change.

Blazin, the methanol isn't used as a FUEL in the water. It'* a COOLING agent. As it evaporates, it cools the air. Colder air is denser. The methanol itself doesn't actually burn in the engine in the manner of combustion.

It causes no need to tune.

Put alcohol or methanol on your hand on a breezy day. You know the effect. The hotter the environment it'* in, the quicker it turns from a liquid to a gas that dissipates. The effect is a cooler charge.

On the higher stall, we're talking about cars that have to drive between one and THREE thousand miles this summer. A higher stall is suicide in that situation.

For a locally driven car or track queen, raise the stall all you want. But you also have to remember that heat kills a trans eventually, and a higher stall CREATES more heat. Far more. Higher stall is your personal choice, but we want Mortehl to know the risks.

Methanol will raise your octane... That is how people running W/I can run 87 octane on a not stock GTP. Have you ever checked out your o2'*?

Todd has a higher stall and I know he has drove thousands of miles on his higher stall and gear change (Intense advertises it for the Gen III LSD). My roommate has a higher stall and gear change and his car is his DD and he drives to home ever break 600 miles away.

Methanol does NOT raise octane. It cools the intake charge to the point you don't get knock or detonation with 87 octane. Do you have an idea of how LITTLE you're actually injecting? Maybe if you put Methanol in the tank of gas itself, it would raise the octane (same thing I do with Toluene, which is much better suited for this). But not the tiny amount of diluted Methanol being injected and evaporating inside the manifold. It does prevent KR, but not by raising the effective octane of the fuel.

The net effect of boosting octane by adding solvents to the tank of fuel is not practical. By the time you boost 87 up in octane with Acetone, Methanol, or Toluene, it'* more expensive than just buying premium to begin with.

In addition, raised octane does not require re-tuning.

Todd has a higher stall and I know he has drove thousands of miles on his higher stall and gear change (Intense advertises it for the Gen III LSD). My roommate has a higher stall and gear change and his car is his DD and he drives to home ever break 600 miles away.
How much was it raised? What'* the gear ratio and weight difference between an SSEi and a GTP? How is the stall affected by the gear change? What gears? What stall?

In GENERAL, raising the stall will create heat. Nearly deadly in Pdad'* case.

You are adding extra fuel to the car in the form of Methanol. The cars computer doesn't know how much you are injecting b/c it is unmetered. The extra fuel is going to make you run rich. As far as the octane - Yah I can put race gas in a stock car and it is not going to help me...

Like I said before if you are basically just misting the intake (esp. with just water) you are not going to have to tune.

Todd'* IIRC is a 3000 stall and 3.69 gearing. Room mate is 3000 stall and 3.29 gearing. Yes a stall is going to make your trans run hotter but you are also doing many things that are cooling the trans in the process like a 160 t-stat.

The converter makes ALOT of heat because when it ISN'T locked up, it'* shearing the fluid (forcing the fluid particles to rub against one another). That'* how a viscous coupling works. In lockup, it produces no heat. When you're in town, you're NEVER in lockup, so you're constantly producing heat. If a torque converter didn't create heat, we'd have no need for a tranny oil cooler. You really don't know alot about torque converters and how they work, do you?

If a TCC fails, it send alot of debris through the trans and then cooks the fluid. You sure that isn't what happend?
