actually they use a air shifter setup

Eh, how much does all that hardware cost again?

how about a truck load of money ..

 

[Nuffice]

Probably close to $120K the car is sweet tho it goes 8's on drag radials

Measuing boost sounds a lot better in PSI than Barometric pressure!

AGREED! wait till my new ricer boost gauge comes in ill be running .00483734 kg/cm3/%_3.147568902654-3468_3876### boost

 

[Nuffice]

haha then again You cant make fun of someone whos car is 3 seconds faster than yours

 

[turbo buicks]

YES I CAN

[ttawd3s]

I saw a supra run 8.9 on drag radials... It was in the $120K area..

 

[Keaka26]

First, I'd like to say whats up to everyone, as this is my first post. I drive a '92 DSM AWD running in the 12's, fairly lightly modified. I think GNs are sick, and us turbo guys gotta stick together

The DSM awd systerm can run into the 8's !!!! But the TC is replaced EVERY time it runs....

I gotta say, this is a little off base, John Shepherd recently put down a 9.0x on street tires, on stock body, all metal, all glass (no lexan)... He runs the factory transmission and driveline, and can put down more than a few passes before needing to do some rebuilding and replacing... Sorry, I just had to back up the DSM community a little there...

As for the skylines, I believe they are low 13/high 12's in stock trim, in R34 form...

 

[ncgreg232]

Hmmm

"more than a few passes" = ???

and this you said was running 9.0x So then how many passes do you think could be made running 8.s? It would seem to me that a stronger TC might be the challenge of the day?

Forgive me for nit-picking, and you certainly can't be faulted for wanting to back up your community, but do that here and you gotta make sure your answering the claim (8's not 9's - yeah, 9.0 is really close to 8's) Oh, maybe you pretty much did it already?

 

[Keaka26]

You know what, I cant seem to remember the exact # of passes, but I was quite impressed when I read it. It was actually a lot, and I cant remember where I saw it.

The difference to me between 9.0x and 8.99 is negligable, as 1/100th of a second is not even repeatable for the most part. Now I can honestly say that 9.1 and 8.99 are miles apart

The other AWD DSM I can think of was in the 8's (Sean Glazer/Extreme Motorsports) , but it had a big advantage as it weighed in at just a hair over 2500 pounds (compared to 2700+ for Shephards car) . Shepherd is going for that street car look, as I said with full steel body, no lexan. Even Glazer was using Lexan at the time. 200+ pounds is HUGE at the 8/9 second level. Hell, its huge in any car.

I certainly dont blame ya for trying to get the specifics from me on the # of passes he makes on a TC, but I just cant think of it right now, and I dont want to make up a feasible number and lie to you guys.

 

[ttawd3s]

As far as I knew he was only getting half track before the car is basiclly FWD... ONE pass.

I bet he gets a "group discount" on TC rebuilds, hehe...

 

[Keaka26]

you talking about glazer or shepherd? I guarantee its not shepherd...As for glazer, well, I cant say...Either way, both of them can rebuild their own TCs Im sure.

It was kinda a joke anyway.

You are comparing apples and oranges as the GN only has a ghost of a chance in the 1/8 and 1/4-mile. How well it does depends on the mods the cars have. The GN is heavier and the Skyline is "only" 2.5L but can make equal HP and beyond what a 3.8L stockblock can hold. It all depends on the mods and who is driving it.

Like a SII GN, Skylines have been modded into the 7s.

Scotty, there is a guy here in Winnipeg with a 240Z with the skyline motor in it. Basically stock with a huge front mount and 14psi and he ran an 11.7@117mph with a 1.78 60ft on the weekend running on pump gas. Neat little car! I had mentioned your car to him.
