R/T....... .133
60'........ 2.411
330....... 6.443
1/8....... 9.698
mph...... 75.37
1000..... 12.494
1/4....... 14.385
mph...... 95.98

This is my third time ever to the track, I have less than 10 runs total under my belt, so I'm still a n00b I guess. I have no weight reduction done to the car. I will probably run it the same way next time, and get it weighed. I know with some practice I'll get the car down a bit lower in the 14s

And the car made 197whp at the time.

Here is a link to my mods.

If you could get some DRs and cut that 60' under 2.0.... you would theoretically be able to cut some relatively deep 13s nice work!

I actually have a pair of Nitto 555R DRs I just found at a junkyard, I should be putting them on some stock NX wheels and head out to the track again. I'll try to work the 2step into this, see if that helps me any.

went to the track tonight...times just a teeny tiny bit better.
the only new modd is installed spacers on intake.

R/T--------- 1.111
60ft-------- 2.334
1/8--------- 9.473
1/8 MPH---- 75.75
1/4--------- 14.669
1/4 MPH---- 93.00

Still running de manifold, and I think is 2'' piping.

Can any do the math to find about what my 0-60mph time would be. Or is there even a way to do this accuratly?

Went to the 'track' this weekend. It's the old airport of Athens, not a real track, but that is what we have for now. First meters was very slipery and that was my clutch also(a little but it was).

R/T....................0.877
60 FOOT.............2.423
101 METER..........6.460
201 METER..........9.769
305 METER.........12.602
1/4 MILE............14.974
1/4 MILE KPH......154.35
1/4 MILE MPH......95.92


Best run with Yokohama Advan A048:
R/T....................0.832
60 FOOT.............2.344
101 METER..........6.263
201 METER..........9.575
305 METER.........12.410

DYNOED 197 CRANK HP BEFORE THE HEADER. THAT'S ALL!

[bill]

Forgot to mention that it was my first time at track ever.

Can anyone point me to a dyno chart that gives a good comparison between an SR20VE with stock cams and (preferably) the same SR20VE with SR16VE cams? I'd like to see the output across the entire RPM range.

Thanks.

Bill, you have pm.

[bigtom]

seems i have been forgotten. haha.

60' - 1.850
1/4 - 12.865 @ 103.25 mph

this was at 189whp sr20ve with sr16ve(blue) cams. i have heard rumors someone went faster, but havent seen the proof. this run was at carlsbad a few years ago. its amazing what you can do with a 1700lb sentra.

whoa bigtom! whereve ya been big guy?

[dansr20]

well Kesi24 claimes a 12.7 i believe on slicks, with around 220whp, which im not douting. Considering ive seen similar results on all motor hondas around here.

Nice clips, your VE sounds nice

[amdeman]

SR20VE standard, 10degrees advance, with Fujitsubo headers, Apexi 'cat back' system, Walbro intank pump, and a new O2 sensor!
Dynoed recently at 121kW (165HP) at the wheels, with 450Nm of torque running lean (NISMO AFPR now installed!)
Yet to be re-dynoed with adjusted fuel pressure.

Sorry, 475Nm of tourque.

I should learn how to correctly read a dyno sheet, BEFORE posting...

[Audio Piper]

sr20ve, stock sr20VE ecu, stock ve exhaust manifold and secondaries, 2.5" mandrel bent exhaust with Magnaflow mufflers, Hotshot WAI with JWT POP, Magnecor wires, NGK iridium (bkr6eix-11), Nismo AFPR at 40psi fuel pressure with vacuum, 3* ignition timing, intake cam @ 4750rpm and exhaust cam @ 5000rpm

[billc]

Audio Piper --

Nice chart. What's the difference between the 2 runs? Also, if you go back to the dyno, you might try switching your cams earlier to see if you can eliminate that flat spot at 4700 RPM.

Thanks for posting the chart.

First run was with stock 5* ignition timing (stock for sr20ve ecu) and 34psi fuel pressure with vacuum hose connected (43psi without). Ended up with a 14.7 AFR on that run.

Kept increasing fuel pressure 2psi at a time and made best power at 40psi with vacuum hose connected which resulted in 12.7 AFR. Advanced timing 2 degrees and got pinging. Retarded it 2 degrees and made a little more power.

I notice the flat spot where the intake cam switches at 4750rpm.

I think I could have made a little more with more time at the dyno but I already took an hour so decided to call it a day. I'll go back soon and try for more.

[chirpin4th]

My new time's (again) just a little better. Same mods, except for fuji header.

.642 -----reaction
2.215-----60ft
9.291-----1/8 ET
76.64-----1/8 MPH
14.464----1/4 ET
93.56-----1/4 MPH
This was my best run, although it was my lowest mph of the night. I was usually at 94 mph.

What tyres and what is your rev limiter?
