racing at drag stripe

ligerx · 07-31-2006, 12:45 AM

tonight i want to the drag stripe just to see want my 2006 reno would do in the 1/8 mile and to see what my car would do againist a car in the next class up by running a SENTRA SE-R SPEC-V with a CAI , and full cat-back system.I stay in my on class running againist ( honda civics, mazada 6 (4-cyc), neons, cobalt ls, sunfires, and more. I was get tried of beating them in races ( drag and street ).

So with my few mods( CAI, muffler, and performance chip) race the spec-v and was very surprise at the outcome. Even that i have lost all three races i do know where i stand. With a best 60ft time of 2.473 and an 1/8 time best of 10.932. The power to weight was better than the spec-v but the 40 or 50hp extra made up for it. I lost againist the spec-v at the closest of 1 3/4 car lenght with 1/8 time best with 10.00 flat.

With a better 60ft time and 1/8 time a reno with could easly run high 9's and lows 10's. One of the problem the I have tonight was the my reno was not sticking at the line but one time. All the other times the car was breaking at the line and the front-end was hoping ( which i think is because of the stock engine mounts ) causeing me to lose trax-ion

With the spec-v short first and second gears if is almost if not very hard to beat of the line but from the rolling start a reno can beat a spec-v. After 90mph the spec-v have no top-end which the reno has a lot of top-end. I have learn in my street races againist the spec-v that a reno can maybe edge out a spec-v.

Now that i know where i stand in racing in the next class up. I can go back and mod my car some more to beat the next class cars ( sentra se-r spec-v, ceilca gt, neons srt-4, cobalt turbos, sunfire gt, scion tc )

Performance chip? Whered you pick that up at? And no UD pully? Tisk tisk. :P

He means those $20 "chips" that you put on where your AIT sensor should be, that are really just boxed 2 cent resistors that fool the ECU to thinking the intake air is a lot colder than it really is.

Yeah. I can make money off those if I had no contious. Its a resistor. Nothing chip like there

I found a whole site that described the what, how and why. I know my way around a soldering iron a little, so I had an idea on wiring in a variable resistor that ran in the range of acceptable values. (There are limits on the resistance you can use).

Wire it in a little project box with a dial and a switch to turn it back to the AIT sensor, when you want to run it normal.

But it's just not worth it to me. Runs the car way too rich.

sorry zipper no ud pulley because it really do not do anything at all in horse power.

but to easy everyone mind about what type of engine performance up-grade i have. well one is made by comptech and the other is made by velocity performance. the comptech it is mainly use for turbo ap but all i'm using it for to boost my ecu settings and velocity performance i use to to change my fuel curve. by using this two i was able to remap my stock fuel system

I do the same thing using watter wetter and a lower temp thermostat. Running my cabby about 30 degrees cooler and the air/fuel ratio is around 13.5/13.7 to 1. By itself the gain is minimal, but as part of a package of upgrades, it does help.
Watter wetter is like 5 bucks and the thermostat was 7 bucks.

Sorry, but I gotta call ya on this. The idea of a proven 20 HP
dynamic, better RPM drop, and less weight on the crankshaft isn't appealing?

I'll have to wait for Master Dog or Kinky to chime in, but I'm slightly confused by those sites. WHat exactly did you add and where

masterbiscuit · 08-01-2006, 12:31 AM

The first link is interesting. But it's basically doing what our ECU does already. Difference is you're doing it manually. Could be some gain to be had, but I doubt it would be much on a N/A setup. It's way more valuable on a turbo.

The second link is exactly what I already said it was....lol.. I like their fancy wording though. "A second feature of the Velocity Performance Module is it's "Extreme-Heat Signal Correction"" So for $30 and shipping, you get 4 wires, a resistor, and a small project box. Total real cost at Radio Shack $4...

Yeah, it tells the ECU that the air in the intake is colder than it really is. And the claim of only losing 1/2 mile per gal, yet gaining 20hp? *coughbullshoicough*

Look, I'm sure there are some gains. No doubt, the ECU is making the engine run very rich right now, which will create more power. But I'd rather get REAL cooler air into my engine and let the ECU richen the mixture properly.

Chips won't do hardly anything on our car. Even with a full piggy back system the most that can be made is .75whp. Our cars already run really rich stock so adding the resistor to mess with the afr more is really dangerous on our cars and I don't think there is much to be made.
