i just wanted to say HI to shep!!!! its gonna be sick when u dip into the 7s man
 
I think if he was auto he'd have a much higher chance of gettin into the mid 7s just my .02 :thumb:
 
The problem with an automatic is that it would suck more power out of the engine, and he's getting through the gears so fast as it is that I don't think it would really help. Not to mention the trap speeds he's running might be beyond what the dsm auto is capable of. Not too sure as I've only ridden in an auto dsm one time and we sure as hell didn't do 175mph.
 
^^^yeah ok dude, step down from your soapbox.

nothing wrong with a little constructive criticism. theres alot of knowledge in this thread. nothing wrong with wondering why he doesnt use auto, more nitorus, more boost, etc etc.

i for one think he needs a wee bit taller final drive ratio, that way he could be in his powerband longer. but thats just me.
 
hakcenter....please read the entire thread. Especially the part where myself (the originator of the thread) said that there is no way I considered any of us worthy enough or knowledgeable enough to help out Shep. It was just a curiousity thread about what others might say or think.
 
This thread should imho be closed, and one debating about shep, and things he has done to his car, should be in a completely different thread. Not how to make the 'worlds fastest dsm, even faster'. Anyone with real ideas of that magnitute should be on his engineering team not on some forum where people with 15second dsm think that an awesomo auto is going to be light and day to the project.

Thats just my opinion. And yes I do think a auto would be faster in a car that runs that low of 1/4mile times. No I don't know everything about The auto trans; Its just from what i seen when go to the track. Almost every car I've seen run really low 1/4mile times were automatic. But hey its just my opinion and I stated it.
 
Actually an auto would probably make him slower. I havent read the whole thread and i am unaware of his whole setup, i know he's using a dogbox....idk if its a standard shift or what but it would make it a hell of a lot easier if it were a sequential dog box...atleast i think?. But then again, Sheps made it this far doing what he's doing so eh.....
I know he has a lot of traction issues and the only thing i can think of that would resolve that would be wider tires, but even then that may just hurt performance since they would be wider. Dahlback racing's 1200hp awd golf uses 305/40/18's and it still has basically no traction from 3-6th
 
The autos will not go 170 + in 3rd and 4th is to weak, not that I would use one anyways. Driving the car is an absolute blast and an auto would take that away. Every pro import in the 6's uses a std trans, they are a clutchless gforce but they are still a manual. You really don't even have to lift with a dog box, I have just not attempted it yet while trying to sort everythine else out.

How do you know what my powerband is? This is not just some thrown together car it takes an enormous amount of thought. Every little thing we do to the car has a lot of thought put in to it including gear ratios.

Thanks Shep, this whole change to an auto trans things keeps coming up in this and other threads referring to your car. It should seem common knowledge that the dsm auto trans would not help you at all as it is not strong enough to even consider using with the hp your putting out. I didn't realize that you hadn't come to not lifting to shift yet. How much do you think it'll cut down your times once you start trying that? Obviously once you get everything else worked out.

Do you have NLS enabled on the AEM?

I am making what I believe to be 1/2 as much hp... I know about what I am making but not sure about JS #'s other than the ones that count... ET... Anyway even at my level making less power. running as single quartet of 160lb/hr alcohol injectors as opposed to staged +2 and using more userfriendly and less thirsty alcohol than him.. It was'nt easy but the results were worth it.. I dont think you understand how much it took to pull off what they did.

I am still not sure what JS does for cold starts on the methanol.. Its pretty cold blooded.

1. He is still figuring out how to deal with and control the current power level.

2. I dont think you can make a transverse auto handle that much.. All transverse autos have a chain linking two shafts. It looks like a 4X4 transfer case chain... Serious 4 wheelers run a gear drive t-case because they break chains. You could do what ever you could possibly dream up to the auto to beef it up but you will snap the chain.

3. On a turbocharged methanol fueled engine you dont need that much N2o as the fuel itself is also an oxidizer and charge temp reducer.. N2O is only for spool because it is only needed there.

Please do not strip your car out and make it tube frame. Back to the topic, making shep faster, how bout one of those magnus dogbox, even though it would compromise the fact that your build your own trans, but magnus claims that their dogmission shaves off .5 sec at most, maybe not in your territory, but its an idea, or maybe a sequential trans? http://www.holinger.com.au/products.html

when I took a peek in sheps interior when I was at midwest mayhem, I noticed that my car has at least one thing common with his, the hks evc boost controller, shep, can you answer me, why do you use that old school thing and not the new gen digital ones? Thanks.
Because the old school one rules,its so easy to use and simple,has rock steady boost control,more reliable,I was never a big fan of electronic boost controllers until I tried an old hks evc. :thumb:
 
I was just reading on exvitermini and although that car is COMPLETELY different than a dsm, i was realizing that idk how much faster Shep is actually gonna go without a serious weight reduction. Im sure 7s are possible at this point the way the car sits, but consistently making 7 second passes i think is a bit much. I dont even know how a 10 second car reacts with traction, etc...letalone a 7 second car, but idk, im just being completly opinionated. I havent searched yet, but are there any other awd cars to break the 7 second barrier? Regardless of what you do Shep, man, im behind you all the way. You have made "DSM" a mainstream name, atleast where im from, and just wanted to let you know(even though you probably hear this a lot) that everyone with a talon that i know atleast wants to run like you.

Hey he could always let me drive, I'm light-wieght. Consider me driving a weight reduction. ROFL
