Automatic DSM 9-second pass - Page 2

slowbubblecar · 10-10-2006

The guy is on dsmlink and has his mods on there as well. His car has been runnign 9's since the middle of the summer if I can remember correctly. I thought his best was a 9.6. I heard about it on there and I remember saying it ran 9's all day long. I don't think that guy is trying to hide anything from anyone. I am fairly certain he is running a T67.

Sounds like the right size turbo for the times, built ither 2.0 or it could be a 2.4 I think ither would make it there on race gas using an auto, with a T67 and supporting mods.

It would have to be stroked in to properly spool that turbo, especially without nitrous. That's basically all I wanted to know. I'm not familiar if it's out for 1g's, but is he using TCUgo?

says who? shep and rau run 2.0s.

a lot of the auto cars run small shots of nawztrous.

1.) Rau/Shep use GT series (BB) - faster spool.
2.) They're built for the track. If a car were street driven, as I'm led to believe from the posting, then it would be stroked.
3.) I'm aware that auto's use nitrous - but this one doesn't, from previous posts.

to be honest, you dont really know what he has at all. you only know what you've been told.

also, ball bearing turbos dont do as much for spool as you probably think they do. they are quicker by something like 14% from what i've read. big wooop.

transient response is what they prevail at, and what they were designed for.

BB turbos sure spin for along time even after the engine is off

That is why the transient response between shifts is so good, once they get up to speed they stay spinning.

Rau and Shep are running turbos quite a bit bigger than a T67, their stuff doesn't spool that fast but it doesn't matter since they rev past 10,000RPMs.

They also make dual ball-bearing T67s now for not a huge amount more than the cost of a non-bb T67.

As far as not having to use nitrous has more to do with how high the stall convertor is setup in the car.

What would having a stroked motor or not have anything to do with driving it on the street??

If you want to get technical, keep in mind that Rau runs a BorgWarner CHRA, not a Garrett.

I don't know how this guy has his ride setup, but if it were me, I would definately want it to spool as quickly as possible. Normally when you size a turbo, you keep in mind when you'd like to see power. Why have a large turbo, but not enough nuts to spin it to see its true potential? I'd find it hard to believe that its something other than a 2.3 or 2.4L

Congratulations on completely dodging my question. Your award is another chance to answer it. I shall even quote it for you.

uhh stroked motor will spool a turbo quicker? I'm considerably rusty but I think that has everything to do with what he was saying.

The power of E-thug be with you!

That's a fast bitchin car! That's something great about AT's.. Much more consistant times. Constant 9's - Man I'd drive that car! lol

What is with the ideology that you need boost on the street? I don't get it. Stay out of the power band if you want to drive it on the street, don't go crazy with the throttle... It's not that hard.

rst95eclipse · 10-11-2006

You wouldn't be seeing peak power - which is what you'd need out of large turbo to run such a pass. It just moves his power band north on his RPM scale. He'd have to rev to 10,000 rpm. And I don't think he is.

Why don't you have someone strap on a T67 on a 2.0 4g63. I'd imagine you wouldn't see power until, say, 5000rpm. Congradulations, you have a 2000rpm window to see power. Not practical, but it does satisfy what you're saying.

The last I checked DSMs can rev pass 7k. Stock rev limit is 7800 for christs sake. Remove the shovel from your hand, the hole is getting deeper and deeper.

That, and Shep revs to about 10,000 on a 2.0. You can even see the tach in some of his videos. And his turbo isn't small.

TheBlizzard · 10-11-2006

Shep revs past that even in 1st gear. His motor and head are built for that though. His turbo size is not any issue considering how high he revs and its even more of a mute point when he is spraying it.

rst95eclipse · 10-11-2006

Again, he's built strictly for the track..........

And as stated above, he does spray. Although he does take it off from time to time.

So what is your point? You want to build a 9 second daily driver automatic dsm street car?
I guess you want A/C, power steering, full interior, 150db system, get 30mpg, and have a towing capacity of 6000lbs?

I bet your gonna do it for less than $1000 as well huh?

Seriously, why don't you enlighten all of us noobs on what you are going to build? Then we can figure out what the hell you are talking about.

If you can get the turbo to spool and build the auto correctly it really doesn't matter what size you want to run.
We were going to put together a gt42 with a 2.0 on a auto and it would have been just fine for a purpose built car. Isn't that the point of building a car? The purpose of it?
High stall converters(what something like this car needs) SUCK ASS on the street to drive. The terms "street car" "daily driver" "streetable" "street legal" are not interchangeable.

If you can't tell I am just having fun with you, but calm down. This car is verified, people aren't lying to you.
