Now seems like the time to get a Vishnu TechII. I think that will be your ticket to the 13's. Can't Shiv use you as a test pilot to show how the TechII performs on an N/A setup? I really wish I could see this.

Nice times Andre! Incredible!

Within the next few weeks I should be up to about the same specs minus the expensive light parts (suspension and aluminum hood).

I have access to someone who claims to do a better head porting job than Cobb. Sounds like fud to me but they've been building race engines for years and they don't deal with individuals. I guess we'll see about that one. Cobb cams, borla headers, cat-back, high flow cat, MRT intake, Tec II.

With only the borla cat back and MRT intake I've been running 15.4 @ 86MPH. Should be interesting to see if the high flow cats, heads and cams take anywhere near a second off.

Default What happened

Andre,

What happened during the 14.3 run with your trap speed? It looks like you let off the gas pedal early or something. Your trap speed doesn't match up with your great time. You are off by at least 3mph. Did you lean out, run overly rich or something? Just curious.

BTW: I updated my 1/4 mile registry site with your 2nd run by mistake. When I get back home (I'm at work now), I'll update the time. Whoops!

How did you go about the launches if you don't mind me asking?
Could you go in to more detail about what mods you have done?
Clutch? Cylinder heads? etc. - ?

Good job Andres!

Could you tell me what mods you used to lighten your car offer the "best bang for the buck??"(in your opinion)

BTW: that 1.890 60' time is awesome!

Wink Well....

...Kevin:
thanks, also when you check your char there is somebody with a faster time behind somebody w/ worst time, back to the point, I wish I had the money for TechII besides it's more for turbo aplications like the Haltech is. About the speed traps there is something I need to tell you: The 1st run I launched at 4000 and shift at 6100 from the beginning, on a cool engine, the second one I did it immediately after without waiting to cool down the engine, launch at 4500 but this time shifting at 5500 rpms so that is the difference. I guess I need to find a mid way shifting time to get the best time with the best speed trap.
I'll try to get the closest to 13's waiting for my ECU mod.

Blind eye:
no ECU yet, I was testing a new personal project, that is the only thing I can say for now; besides the fact that it worked very well.

dOOf:
If you remember Josh already ran 15.0 with intake and exhaust only

goose :
I just anwered you above.

Rich L:
my list of lightweight mods are above on my first reply, the cheapest and most effective are the bumper inserts, but be aware that your car's height will cange on the front. Also major improvement w/ the lighter flywheel, both things from Pam at ISR Performance

15.0 with only an intake and exhaust? That's .440 off my best time with the same sort of mods. I wonder if it's a difference in the driving or a difference in the cars? There don't seem to be many different ways to accelerate fast. I'm nice to my gearbox and my times of the day were almost all within .100 of that.

Where is this 1/4 mile registry?

Default A suggestion!

Andres,

I have a suggestion for you. Shift your car right at 5800 or between 5800-5900. 6100 is too high to shift for our engine's torque curve since the powerband falls off to much at that rpm range. I found this out when I was playing with the different ECU's I had. I had my stock ECU, a 2.5 Legacy GT ECU and a 2.5 DOHC ECU along with their TCU (Transmission Control Units). The best times I got was with my stock ECU/TCU combo which shifted at 5800-5900rpm. The Legacy shifted at around 6100 while the DOHC shifted between 6400-6500. The engine sounded like it was roaring and I thought the car was faster but my times told me a whole different story.

Try your 4500rpm launch while shifting at about 5800-5900rpm and I guarantee you that your best times will come out of it. I'm not just talking 1-2 shift but 2nd-3rd and 3rd-4th if you are going that much faster. This isn't based just on my runs but the torque curves and powerbands of most of the dyno runs I have been looking at over and over again on this message board. I'm putting my $$ on this that with a 4500-5000rpm launch and shifting at around 5850rpm, you'll get a 14.0-14.1 in the 1/4 mile. Good luck and happy 13's.

Go Andres, Go.

Andres
Yes, I believe the chart is all fixed. Thanks for pointing out the error(s).

BTW: Andres...I keep looking at your times over and over again. I think I am even more excited than you about what potential your N/A has. I keep seeing you run a 13.9-14.1 according to your runs. At 96mph in the traps....I can't get over this. I wish you were in the Northeast right now. Our night time temps are in the high 50's because of the cold front that just moved in. This is record breaking time now. If you inspire me enough, I may even have to go out and get an intake, new rims, and put my Remus exhaust back on to try to break into the 14's...Nitrous style.

Let us all know how things go.

Kevin, would you drop the clutch at 4500 rpm or slowly ease it in?

I would do exactly what Andres has been doing, whatever it is. Apparently it has been working ok for him so you would have to ask him. I don't know what would work exactly but he's got a good feel for his car and his times show what works and how it works. So however he had used his clutch during his 4500rpm launch is the way I would continue to do it. Seems like his tranny/clutch is holding out fine just the way he is doing it.

I think you should do whatever you could to preserve your transmission and clutch. If dropping the clutch is better than letting it slip for longevity, than that's what I think you should do. I launch my car with Nitrous from a dead stop (which is a big No-No) so you don't want to ask me what I would do. Since I'm not familiar with manuals (I'm a diehard autotranny nut...*gasp*), I would be the wrong person to ask.

Any comments Andres?

Default I drop...

.the clutch, but my friend Jason who has an RS w/nitrous and is an experienced drag racer says it's better to let it go "gradually fast" to me that means drop it!
Now Josh in Dallas has an RS w/ exhaust and intake and did 15.0 so he drives like a maniac but workes for him, launches at the rev limit, and shifts at red line also.

Damn Andre, that is fast. Your times are within a tick of my WRX time. I saw your car at Cobb when I visited Texas. Josh is way to honest, he wouldn't let me drive despite the amount of money I offered him.
