Yeah, it is funny when something new (new to DSMers) comes out and everyone thinks it makes them look cool to come out against it. The same thing happened with E85. What they don't consider is that their incorrect statements will live forever on the internet for everyone to see long after...

Yes (and the Road Surge box bypasses the TCU, so it doesn't matter whether or not you have a TCU).

You could always hook it to a boost switch as well. That is the way people used to do it.

The only time I've seen this, a speck of dirt got into the valve body and was keeping a check ball from sealing. That being said, it was right after doing a shift kit. If you haven't had the valve body off, it seems a lot less likely.

Low fluid will cause the same thing.

So is the rear diff the same between both groups?

Could this happen if he installed the manual starter? They are definitely different starters.

I've got about 12,000 miles on my car since I bought it in 2003, and I had just broken my second manual transmission before I made the switch to an auto. That is 1 transmission every 6000 miles. I obviously don't drive my car on the street that much - probably about 1000 street miles for every...

I'm not understanding either. I think it has been well hashed out that you can't get a 1g transmission to lock up the converter no matter what you do. Are you saying that this converter is the exception to that rule - I'm doubting that, but if you can provide a link to someone who has...

The stock trans is fine - you just need something to increase the line pressure when you on the throttle to extend the life of your transmission.

Yes, I was installing the IPT end clutch kit.Getting the snap ring back on was a PITA, but otherwise, it wasn't bad at all. I didn't have any kind of wheel bearing race or anything else like that to compress the return spring, so I ended up using 3 c-clamps - it was very tricky and that alone...

Yay, I have 4th gear again!

Sweet! I was planning to do my first end clutch tomorrow, so your timing is perfect.

It is just a little toggle switch to switch between the TCU and the shift box. Nothing fancy. The shift box has a bunch of wires going to it, so it is nice to be able to stuff it out of the way when you aren't using it.

Maybe the transmission is in limp mode, but I don't feel that the OP has really established that fact. He said the car accelerates sluggishly, and based on that and that alone, he and everyone else jumped on "TCU limp mode". I would at least verify that when it is in 1st gear that the car...

My setup is a little complicated, but I probably only drive my car 500 miles on the street every year, anyway. Even so, I use the Road Surge box for full on drag racing and use the TCU with IPT's boost controller when I'm driving around town (I only use lower turbo boost when using the TCU -...

I was just wondering if anyone had any estimates to how far increasing the line pressure in an auto can take you by itself - ie, no valve body modifications, no internal transmission upgrades, just increasing line pressure. I've seen guys running 10s who it seems have done nothing more than...

Just do the blue wire mod in parallel with the normal blue wire and put a boost switch to break the blue wire at 5psi (forcing the circuit through the resistor).Edit: or use multiple resistors like IPT's boost controller and use more than one boost switch.

I haven't raced my car as an auto yet, but I'm imagining that it is a bit of a challenge to pre-stage, put it in neutral, rev the engine to get vacuum, push the brake down, put it back into gear, start brake boosting, let the car creep forward enough to stage as boost starts to build, then hold...

It sure would be nice if someone could figure this out, though. If someone came up with a mod that would allow the use of a transmission brake, even one that required internal changes to the transmission, it would sell.

I agree that the manual is more fun up to a certain power level. When I was running low 13s, I could make a perfect run down the track almost every time. But as I got into the 12s, especially the low 12s (with trap speeds that should have resulted in mid 11s), it became harder and harder to...

Alright, my car has been converted to an auto and I've been driving it for a week now, and I can tell you that it is MUCH more responsive as an auto and it spools much faster, just as I predicted. And hammering it in a gear that is too high for the speed you are going (even if it doesn't...

Agreed - I don't know why people always want to convert to a manual and make their cars slower, less reliable, and harder to drive. If you increase the line pressure (every other post in this subforum deals with doing that) it will handle the power you are talking about. You'll also want to...

You want it to shift softer at full throttle?

There are also the homemade stuff.

Sounds like a good idea to me - I haven't looked at the Road Surge box up close and personal, but my understanding is that it is made to easily be hacked so that you can use it the way you want (the maker mentions that a paddle shifter could be wired in). I think you are on to a good idea if no...

I know this thread is a month old, but I made 350whp at 23psi on a Dynodynamics and yet still trapped 117mph at that same boost on a 3300lb car at the track. That is a trap speed calculated 410whp. I think making 320whp at 21psi is fine, but I would be concerned if it isn't making more power...

I work in medical research and see this same phenomenon in health - in fact, I'd say 90% of all health myths are the result of correlation without causation. An older person takes some medication for the first time and has a heart attack a week later. Did the medication cause the heart attack...

Did you check your transmission fluid level?

I can see why a person might want to put the heat exchanger right before the intercooler, but I wouldn't do it that way - mainly because if you use ice water, the heat exchanger will work in reverse and heat that water back up to near ambient before it gets to the intercooler. On the plus side...

Tank -> pump -> intercooler -> heat exchanger -> tank

I've got the Meziere 20gal/min pump - it flows very well, but it isn't overkill. I wouldn't have bought that one due to the price, but I found someone who bought it to use as an engine coolant pump and changed his mind, so I got it cheap. I'm using the 3/4" hose - I'd say it is maxing the...

Uh oh, another blow to the "W/A intercoolers are only for drag racing and aren't streetable" crowd. Ford is putting one on the new turbo-diesel trucks. I guess they must only be for drag racing?Turbocharger The 6.7L uses a Garrett single sequential turbo (SST) with variable geometry, a...

Yes, you can mount it in the stock sidemount location. I don't know what you mean by the "uppermost pipe". Assuming you are talking about the highest point in the system, people don't purposefully put their intercooler at the highest point. In fact, ideally you wouldn't put it at the highest...

Since either no one knows the answers to the above questions or they are too lazy to spend 20 seconds answering them:1. I ordered a 3500rpm stall - we'll find out.2. Based on the instructions for the the A/T IPT boost controller, it IS a variable blue wire mod (for people who want the...

THAT I agree with - especially if you aren't in the throttle very much. It can be pretty annoying trying to take off at a stop light "normally" and is also annoying if your car is loud, since you find yourself revving it everytime you take off from a stop light. Still, if you have to step on...

I do think YOUR 60' time and 1/4 mile time would be vastly improved with an auto... If you don't mind your current numbers, though, stick with the manual. I for one got tired of having to choose between raping my tires or bogging when launching my car at the track with that 1 in 10 "perfect...

How am I not explaining it? What part of higher rpms = faster spool is so hard to understand? I've repeated it in ad nauseum detail 3 or 4 times already. Do you think I like writing 5 paragraphs of detail just to get a 2 line "no I'm sure you are wrong" type rebuttal?

So why don't you address my arguments instead of saying I'm wrong and just making assertions? When you are in an automatic and the torque converter is locked up (ie, just like a clutch) and you step on the gas, does the torque converter unlock or not? If it unlocks, does your rpm not then rise...

Do you have a link? I don't see any such thing on Kiggly's website: Kiggly Racing - kigglyracing.comNever mind, I found it.

But unlike a manual, your rpms rise when you step on the gas in an automatic because the torque converter unlocks and slips. Your clutch in a manual holds a constant rpm. So yes, they will spool the same at the same rpms, but you will get higher rpms when you step on the gas in an automatic...

Since I didn't directly answer your question, I've never had a high stall lock up torque converter, but in my old Chevelle, I had a regular 3500rpm stall converter and it was a blast to drive. It was a lot like a regular torque converter as long as you weren't stepping on the gas much, but the...

An automatic will help spool up in virtually all conditions, especially if you have a looser torque converter. Consider the following situations - you are on the highway in your highest gear with the rpms at 3000. You need to pass someone so you push the throttle about half the way to the...

These are some pretty nooby questions, but I went back a few years through this forum and didn't really find the answers I'm looking for.1. I currently have a manual setup but am converting to an auto. I currently hit about 20psi by 3500rpm and am at full boost before 4000rpm in 3rd gear...

No, I don't know how you came to that conclusion from my post. I said that meth further cools the intake charge, and no matter how cool it already is, you will benefit from cooling it more (within reason). I also said that methanol increases your octane which will also benefit you (because you...

I agree - the water flows too fast to heat soak from simple underhood heat (and the metal on the outside of the intercooler is stainless steel which doesn't transfer heat that quickly compared to the aluminum core). You can never have too cool an air charge (alright, you technically can, but it...

I have the same IC as you and I have similar results whereas when I had an A/A my temps would rise 40+*. That cooler air means a denser air charge entering the engine and more HP. The critics won't buy it though. They are convinced that it is only for drag racing and isn't streetable, no...

Oh, I just noticed that you are having trouble with getting the manifold to mate to the head. I'm not sure why you called this a "S256 exhaust leak" since the turbo would have nothing to do with that.

I've heard that some of the bolt on turbine housings aren't threaded all the way through and your bolt will bottom out before the seal is tight. That might be what you are seeing as well.

It kind of looks like you got a little spark blow out on that pull.
