A local car club had a day at the track this weekend... and I was pretty happy with the results. I went in my street trim and all, so traction was a HUGE issue but still with any kind of a decent 60' the car should be pretty deep in the 10s.

Its a 26 powered S14. GT4067 with all the supporting mods, on 20psi. I just did the e-85 tune that morning and found that I am clean out of fuel at 20psi (actually on the the supply side since fuel pressure drops), so I couldn't give anything more than 20psi a shot.

I lost the slips at Cheesecake Factory which kind of sucks, but the good news is that one of the people in the club got some shots of the car and ETs. IIRC I got a bunch of 2.2x 60's and one 2.1 on the best ET run.

Without further adu, this is the best ET and best MPH runs:

Wow.

What pump are you running?

Looks great man, you should be proud of that one. Did they nitpick you during tech? They really went over my car when I went last time.

Yea I'm really happy about the 131mph, takes some serious power to do that. Can't wait to give some ET Streets a shot!

Yea GLD got a lot more strict after some of the big name drag racers got hurt/died. For me they weren't too bad, they looked at my helmet and made me pop the hood. I'm not really sure what they were looking for though, since I'd bet they really didn't know what they were looking at.

As for the pump. Right now I am running dual intank walbros with a -6 feed. Over the winter I will switch over to either dual bosch intank, or some reliable external pump with a little bigger feed. Probably also step up to 850s or 1000cc injectors (up from the 750s I have now).

Either pump setup should easily outflow the walbro setup under high pressure. I just want to make sure that it is reliable and reasonably quiet since the car is very much a street car.

9.5" wide. Tires are 285/35/18 Nitto 555Rs. They are great on treadwear and still have decent sidewalls on them for handling. Great tires for the street, but they just can't handle the power at the track.

I'm just going to get a set of wide 15s and get a set of ET Streets that I can use for fun weekends on the street and at the drag strip. Still a little too nervous to move to full blown slicks.

Count me in as well, would be a lot of fun.... and cool to see other RB setups in the area. I hardly ever see another RB S-Chassis around.

Anvil:Honestly I am not to sure on the power, never had it dyno'd. My guess is that it would be somewhere in the low 500s as it sat on 20psi & E-85.

The rear end (well almost the whole rear subframe) is from a R34 GT-T.

WOW Great MPH on that!!

Def get you some Slicks, Your only problem then will be getting too much traction and bogging.

With a nice 1.5 60ft you should see a good 10 sec pass.

But tech will kill you. I would add a Roll bar on your list of mods for the winter
