This is beginning to get well off topic, but I think it still deserves a reply.

I have swapped back to the AT. The AT puts down power better in a traction-limited vehicle, such as mine, than the MT ever could. As many people know, TRE was helping me with the 5-spd transmission. I had no problems whatsoever with the TRE trans. It had about 35 passes on it this year and was removed in perfect working order, I just wanted to try the auto again.

The AT I'm using is NOT an IPT transmission. I have worked with IPT on a few parts and strategies on how to make things work and live better. I built the transmission in my race car (using some IPT parts). This means that when stupid things go wrong, like the valvebody issues I had the first time out, it is MY fault. This also means that when there is a combination of parts that hold power and don't break, it is BOTH mine and IPT's information. I just want to make it clear that even though IPT is not building my AT, they certainly have all the knowledge and expertise needed to make a trans that holds power as well as or better than what I've cobbled together. Also just to clear this up, I am running my own electronics to actuate the shifts.

That 9.965 pass was the one and only near-full pass I had with the AT. I haven't figured out how to launch the car yet and I also haven't dialed in the proper amount of boost during the first 1/8th mile. There is a lot more in it. That was my last pass of the season and I almost lost the car during it. The block split in cylinder #1's wall at about the 1000' mark and about 145mph, connecting the coolant system to in-cylinder pressures. That is why my 1/4 trap speed is so low, I was catching the slide all the coolant threw the car into (it blew a hose off when the block ruptured), then on the brakes well before the end of the track. I won't see a real time from it until next year, but this did allow me to tear the trans down and see that everything in it is doing just fine.

If there were any questions I missed, please ask them in a single, coherent line. I became very frustrated weeding through the large blocks of unformatted or paragraphed text and skimmed through them quickly.

Let's take a step back for a minute. Invader, Eclipsei95cl and others are asking if 400whp+ A/T daily driven DSMs are a reality. Well, the "fact" is, not many people here know for sure. That is the only "fact" here. Telling people it's a "fact" that there aren't any until someone proves otherwise is the reason why the internet is so dangerous. That is not how facts are determined. That just proves that there is no evidence either way. The only thing about that statement that is "fact" is that you don't know of any - which doesn't mean anything to anyone here.

You have people on one side who are referring people to a vendor that has given them a good product and good customer service, and then you have people on the other side who are discounting those referrals because the vendor hasn't given any proof that their product can support high horsepower in a daily driver. With the A/T market so small in this industry, and knowing how customers usually only contact the vendor when something goes wrong (not when it goes right), it would seem difficult for (and unfair to expect) IPT to back up those claims. They're at the mercy of the customers to advertise for them when they hit those goals. Bottomline is, there isn't an easy way to prove this as "fact" either way without knowing every single A/T owner that has tried to go over 400whp.

I think it's safe to assume that there aren't a ton of people that have achieved this goal. If you really want to get something out of this discussion, it would be better to ask these questions - if there aren't that many people making 400whp+ on an A/T daily driver, how many people do we know of have gotten to that mark only to have the tranny fail? If it failed, who built the tranny, who installed it, and what were the conditions that the tranny endured? Are people simply not making that much hp on an A/T because they can't find a reliable solution or is it simply because not many people have reached that goal with an A/T? Unfortunately, not everyone who could give some insight to this discussion goes online, so we might not ever have the answer. The question shouldn't be - "are there people making 400whp+ with daily drivers?" - because we may never know. The question should be "why aren't there that many people making 400whp+?".

Nobody here has the right to call anyone names are make accusations. Some posts in here could be considered vendor bashing and/or flamebait. Let's quit with the accusations or we'll have to ask some people to leave.
 
I am no way trying to bash ipt they are great..Look at some of my past posts and you will see that I recommend there shop to everyone. Also I have a ipt rebuild kit in my car now...So y would i bash if i had there kit in my car? In my recent couple posts i did say in there that the answer to our question is simply we dont know as you have stated and I thought it was done. But 98talon comes back with his bashing and what not. I agree 100% with ya luda and we arent trying to bash nor give false info. Its just that we asked the question and like you said the side that has had good service from ipt all claim it can withstand 400whp..But we just pointed out the fact how can you say that when we havent seen anyone do it and we asked john to tell us who since he built all these trans for these guys he should know of some right? well we didnt get an answer and 98talon just accuses us of bashing them when were not. So yes in the end the answer to the 400whp on a ipt trans/daily driven car is simply No one knows...

Hope we can just end that convo and get back to what the original postee asked..Even though i think he had his question asked already.
 
I wonder if there's any way of determining that out of the top, say, 20 or so on the A/T DSM Fastest Times List, how many of those cars are daily drivers. I don't think even Russ would be able to tell, and he's the list keeper. Anybody have more insight?

With a few exceptions, (Russ and Kiggly) I think most of them are DD because most of them are in the low 12s, high 11s... I hope to be in the 11s next spring once I get my FP3052, cams and Magnus Intake. With those high stall TC's, the gas mileage goes down and it becomse less of a viable option for driving back and forth to work if you have a large commute.
 
Another question for you guys to keep this post on track :rolleyes: . If I want to hold around 300 whp, do you think a end clutch, shift kit, tranny cooler, and custom tc would do it?

300whp on an AT is hard to do beacuse of the tremendous drivetrain loss. That is borderline breakage territory you are talking about with the stock transmission... I would say that's about 350 - 360 crank Hp perhaps..
 
But can you call an A/T with end clutch, shift kit, tranny cooler, and aftermarket TC "stock" though? I mean, it kinda is since you haven't rebuilt the innards (that's the technical term), but those basic mods should improve reliability somewhat, I would think.

I'm only up to 254, though, but on an almost completely stock tranny (end clutch only so far), but I feel that I should be able to get 300 with a few more engine mods, plus the tranny cooler and shift kit that are sitting in my garage right now waiting to be put on. :(

When I say or anyone else in the AT world says, "stock tranny" I think they mean, the guts and not the end clutches or valve body mods.

If you weren't bashing or making accusations, then don't worry. If you read my post again, I only referenced you as asking the question of what is possible - I didn't say you bashed anyone. There were others that began name calling and making accusations - which crosses the line around here.

The bottomline is, we don't want our "assumptions" to be taken as "fact" by people who are reading this thread. That's how rumors and misinformation start flying around. And that is why I needed to set things straight. Assumptions are not facts simply because they cannot be proven untrue.
 
As late as I may be to this thread, I have to chime in.

My stock (shift kit, endclutch, big cooler) trans has survived over 30,000 miles of abuse from a 50 trim running 22-25 psi daily driven. I may not be putting 400 hp to the ground, but the high side of 40lbs/min is nothing to sneeze at for a daily driven A/T.
My trans flares a bit shifting at part throttle, but it always has since I drove it off the lot with the T-25. It doesn't show any real signs of giving up anytime soon.
I'm going to a billet high stall TC later this winter and will most likely leave the rest stock until it dies. The car now has 93k. We'll see how far it goes. ;)
 
I was actually waitin for you to find this thread, LOL :thumb:

I remembered readin your profile some time back and discussin the drivability of your 50 with you,

good deal
 
Dammit, where were you when I was talking about you earlier..... ;)
And answer your phone :D

Who knows..my trans lasted 6 months after the install of those parts, with no track passes. Prior to install, I had made at least 20 passes on the bone stock trans. Who knew what condition it was in even before I owned it.

Type like that again, and your post may disappear. :|

No, Yes, Yes, No, Yes
HAHHAHAA....well said Matt
If you look at IPTs site, you'll see what it comes with. But, simply, the TC and LSD (which is a phantom grip insert with the green spring) were the only other "additions" I needed to make other than his full trans.

sorry i was running late for work so i just typed really fast
to get what i had to say and left

but at least someone managed to get what i was saying
