Stock SR T25 1/4 Mile Times

[2_Liter_Turbo]

Just curious what other people are getting with the stock T25 on their SR20DET Cars.

Mine is an S13 SR20DET Redtop II in an S13 Coupe (full interior) running 14 psi on the stock T25 using falken street tires (FK-451's). A few minor mods like exhaust, intake, and bigger IC.

13.48 @ 104.1 mph with a crappy 2.111 second 60 Foot, on a poorly prepped track.

[realslow]

i ran a 12.9 with greddy front mount,and intake manifold as for boltons. 2.2 60' alot depends on sea level and outside temp. 2.1 is a pretty decent 60' for street tires

[nmsil-eighty]

you're right where you should be, for an SR20 w/T25 and minor bolt ons, mid to low 13sec passes are very good, 12.9 is fantastic

[GreekRPS13]

wow didnt know you can run 12's on that type of setup awesome

time slip! that would be great!

wish i kept mine.

I ran a 13.0@106 MPH with the stock turbo in like the summer of 2002...

good times.

[2_Liter_Turbo]

I know I could have run faster than a 13.4, I just didn't have enough time to give it a shot. My best trap was 105 mph, and I ran a 13.52 doing that. Oh well, next season, I'll be blowing those times away, lol.

[PS13Hotness]

13.61 @ 106.4

Baldy no-grips on the rear... my 60's were 2.3 - 2.4 that whole night.

[SoSideways]

Where are you guys shifting at?

My best was only like a 14.4 @ 98mph w/ a 2.4 60' or something like that. Also ran that time with both 7psi boost and 10psi boost.

[PS13Hotness]

1st - 7500
2nd - 7200
3rd - 7000
4th - 7000

I don't think I actually shifted into 5th.

[Cashizslick]

^ +1.

I usually ride first all the way up . . . Second and Third are where I shift at 7k ish.

[2_Liter_Turbo]

For me

1st - 7000
2nd - 6500
3rs - 6000

I'm in fourth when I cross. I also launch around 3500.

[Vatche]

you should all be happy i have 2.6 60' all day long. and cant even break 14's someone donate me a lsd? :)

[leonb2004]

A decent driver should be able to pull 2.2s on decent street tires. Get a set of drag radials and run 1.8s. They say every .10 you cut off your 60, cuts .20 off your 1/4 mile time. Not far from the truth.

[SoSideways]

Friend of mine ran a 12.9 @ 108 with stock T25. S13 coupe. And he shifts way early. Like, he said he shifted at like 6k in 1st, so he can be in 2nd gear making some power under boost, and he shifts at like 6500rpm (T25 really chokes after that anyway).

::shrug::

I haven't tried that method yet.

[streetracerb86]

With my s13 hatch the best i could do until my cheap ass coupler blew was 13.9 with my t25@14psi. I only had an upgraded fuel pump, apex'i n1 exhaust, and a vlsd.. Given that was my first time at the track also.

60'.... 2.209

Backed that up with a [email protected]

Thats with street tires, 14 psi, fmic, intake, exhaust and in florida meaning I was really close to sea level. I think I shift to slow or something. Do you guys "power shift" or just shift like normal? ie. letting off the gas when you push the clutch in..

[SoSideways]

^^^ Are you who I think you are? If so... this is Data... the Asian guy w/ the flat black S13 hatch...

No reason to power shift - that will only destroy your car.


That trap speed is a little low . . usually 240's w/SR's trap around 105ish . .

[SoSideways]

His 60' is also not a 2.0 If it was a 2.0 then I can see how the trap speed might be 105mph ish.

My trap speed was only 98mph and running 10psi, and had a 2.3 and 2.4 60'

[TheTimanator]

hmm, I have no idea. That run was back in May of last year at Orlando Speedworld. The only guy I remember from that night was a guy with a white Kouki S14.

Also, interestly enough, that same night I managed a 2.121 60'...but that ended up being a 14.059@99mph.... might of had someone in the car with me on that run...I can't remember.
Anyway, you guys have got me thinking that I could do a lot better without changing the car... hmmm

[SoSideways]

Uh... I was there at the first OSW drift practice... umbrella... does that ring a bell?

in that case.... nope I'm not who you think I am :)

[JTunedMotorsports]

91 s13 cp Sr20det Red top swap..jdm VLSD HKS EVC 12-13 psi stock t25, no cat,Full bolt ones..17 inch 5 zigens..13.2 shitty 2.1 60 fts..Trapping 110-111...why so bad?

[SoSideways]

in that case.... nope I'm not who you think I am :)

:( I have been defeated.

Oh well, I'm gonna go back to OSW with some friends hopefully when money isn't so tight, and crank it up to 14psi and see what I can do.

[fohahz]

::eek: wow thats pretty quick for what you got. nice times dewd

[savannaae]

I ran 12.95 on my redtop hatch w/ BPU's (FMIC/3"/Boost controller @ 13 LBS. I was running bald 235/45 BF Goodrich G-Force Sports at 28PSI. 2.0 60 foot, no speed shifting, +100 degree track temps... the track was well prepped, though.

I'll see if I canm dig up those slips, it's been more than a year.

[Slideshow801]

wat do you guys think i will hit at the 1/4 track? im in utah, have s13 black top sr20det, '90 fastback, full interior, vlsd, front mount, 3in. down pipe, no exhaust, yokohama street tires, 15 psi, stage 2 clutch, laucnh control, and other little stuff. i have beaten a 13 sec. turbo Si and my buddies rb25 powered s13 on the freeway pulls. this year will be the first year i run the sr at the track

[2bad240]

i ran a 12.51 @ 111 with t25, greddy front mount, and full exhaust. i am running a tomei ecu but i dont know if that has any thing to do with it. but it might be the 1.68 60' i launch at 5k and it just leaves.:hsdance:

I'm assuming you have slicks or drag radials to get that kind of 60'...

[steve shadows]

1.6 are possible with drag radials and an lsd of some sort.

I used to run 1.90s with an open diff and drag radials way way back.

Best was a 13.01@107 iirc.

best ive ever hit was a 1.60 with (no 2 step) bf goodrich comp ta's and a t04b on a stock sr block/head etc.

2 step makes things easier but depending on routine servicing and condition of parts it can wear stuff out.

good times.

i think the mid 12s are thanks to very light cars (ie stripped or xe model's etc).

[nlzmo400r]

usually with a ridiculously awesome 60ft (1.6-1.8) your trap speed may drop a little bit.

[2bad240]

i was running fuzion hri's. but since then i have got drag radials and picked up in the eigth mile but i havent been back 1/4 mil YET. should have been like a 12.2 or something close to that.

[FusionR240sx]

wow, looking at this makes me happy...low 13's with stock t25... i'm lovin it. i'm gona pick up a 1.5 way and then some spark plugs n wires and head to the track in a month or so and see what i can do... first time at the track tho so you all can't laugh when i bring back the time slips.

[BlackZenkiS14]

on my OEM 60k mile T25 i went 13.6@102. Stock SMIC, stock injectors, stock maf, stock tires, stock ecu, no tuning. My only mods were a 255walbro, full exhaust, and an intake filter.

[georgesal]

60'.... 2.209
330.. 6.004
1/8... [email protected]
1000' 11.908
1/4... [email protected]
then on the next run i got rod knock damn oil pan

[georgesal]

^^^^^ oh yeah that was on stock everything, stock airbox, stock exhaust and downpipe, even stock fuel pump

[Automato]

i'm going to bring this thread back from the dead because i just ran the 1/4 mile in my stock t25 today. this was @ 15psi and in upstate NY. still lots of room for improvement in my launch and reaction time.

ebay tubular manifold
hks fmic
850cc injectors
3" exhaust all the way back w/testpipe
z32 mafs
powerfc
255 walbro
kaaz 2-way w/street tires (225/45/17)

R/T : .850
60' : 2.131
330 : 5.586
1/8 : 8.409 @ 88.35
1000 : 10.813
1/4 : 12.841 @ 111.8

[whiteytighties]

I'll add mine from a couple yrs ago on 14 psi, Hi-pro fmic, 3" dp/testpipe/catback exhaust, and K&N filter. Fuzion HRi 225/50/16 @ 28 psi all around. Full interior, almost full tank of gas, tools/books/spare shoes,shirts,pants/spare tire and emergency equipment...s13 fastback.

60ft: 2.2
1/4 : 14.2 @ 85 mph

I mishifted into 4th gear and just let the car roll all the way to finish line. Usual trap speeds are 99-100 mph @ 14.2.

wanna bump this up for new times. same setup still but upgraded the tires to 255/35/18 BFGoodrich GForce Sports

60' : 1.93
330 : 5.370
1/8 : 8.223 @ 84.57 mph
1000 : 10.656
1/4 : 12.708 @ 109.8 mph

i feel like the car in its current setup can hit 12.5 even with street tires if i play with my shift points a little more. we'll see if i can make it out there one more time before it closes for the year.

[rb25_s13*CHUKI]

This Is one of the time slips a good friend of mine pulled out at Famoso drag strip..

60' : 1.5's << Micky thompson Drag slicks
330 : Not sure
1/8 : 7.220 @ 98.0
1000 : not sure
1/4 : 11.7 @ 122

T25 with 550cc nismo injectors, Tomei Tuned ecu, HKs 264 cams, 3"inch exhaust, Hks Fmic and 30 shot nitrous... Doesn't use the bottle after 3rd gear... Cusco 2-way lsd.. Full Interior!

I'll get his actual time slip his 1/4th might be faster but thats what I remember seeing..

[s13dan]

I run any where from 13.6-13.9 with 2.1or 60foots.
Traped 106 with 14.5lbs of boost,fmic.walbro and 3in exhaust so not completly stock but close.

[handinpants]

14 psi on the stock T25..... keep running that... its good for your turbo

[spikNspan]

^^^ haha, right.

this thread is totally inspiring! makes me want to up the boost and get some dr's and hit up the track, see what my baby can do. I would love to run high 12's, this thread is making me wet! :keke:
