SR20DET Performance Questions

Does anyone know how accurate the Greddy turbo Timer is at measuring 0-60 and 1/4 times........havent had a chance to get to a track here in germany and sure as hell cant find a dino. according to the timer I ran a 0-60 in 4.9 and a 1/4 in 13.1
I have done alot to the car but dont know if I can trust this little thing.

It was a stock 200SX (german spec silvia) with a stock SR
Spent all the money I saved in Iraq on the thing
and I have killed 2 M3's 1 new mustang GT, and one carrera
anybody have an idea what I should be running or what amount of horsepower I should expect. Even the Nissan dealership who installed everything has no clue.

I am running it at 18 PSI and its a 1999 Z spec

Yeah, really i dont know how accurate they are, i would just take it to the track and do a couple of runs just to be sure, and then compare it to that.

it might not help to much but try a dyno program for
the pc .. it will give you some feel for where your at i have desktop dyno 2003 some where but dont ask me how to use it.

that actually seems like slow for the S15 and turbo that you got. i mean your car runs a 13.8 stock. with a upgraded turbo running 18 psi should be in the 12's.

Well, if hes taking the new ///M3s, the SMG runs a 13.2 and the stick runs 12.8 (with good drivers), so I'd say 13 flat, maybe a bit faster?

Its Not an S15 its a special edition S14a, last model made in europe (unfortunatly) Its the same as a 1998 just came with BBs 18 Inch rims, leather, power everything, 5 speed, and a little badge numberd 1-800.......this one is 238. After a couple of runs on the back roads today I was able to pull a 12.82 and a 0-60 in 4.89....................still cant figure the horse power

well you have to dyno it to find the horsepower
