Nice times.

Mid 13s on a 1.8 60ft clean run sounds definitely possible!

Btw, how much of 91 octane did you have and how many gallons of 103 did you add? Just curious.

I believe I had about 1.5 gallons of 91 and 2.0 of 103. Not sure what that ends up around. I had about a 1/4 tank of gas in the car.

I think my trap times are a little higher than the other guys mostly because I'm really close to sea level. Either that or maybe I shift a little better dunno.

I don't know what the 0-60 would be. I'll have to test that seperate somehow. I've never actually done a 0-60 test before but maybe I'll get one of those new G-Force Pro's I think they're called. Or G-Tech. I'm guessing based on Sport Compact Cars 0-60 I did it in 5.0 flat or 5.1. They did it in 5.0 with similar times. That's on the 1.8 60' launches and not the 2.0 sec launch. I'm estimating for myself since I actually missed 2nd gear. I think the car is pretty much on par with what mags are getting. Slight differences with drivers of course.

You should try some double clutching, even with Synchros, makes the Synchros more tolerant.

Here's an article to help you out:

What exactly is "double clutching"? I've heard so many conflicting stories that I'm not sure what's true!

Double clutching should only be used when your gearbox is damaged or the synchros aren't working to help get the stick in gear. It should never be used as a method to gain speed or improve time in any form of racing. Simply because it won't. After you read the description of double clutching you will see why it's a waste of time.

Double clutching basically is that. You depress the clutch to put it in neutral then release. Depress the clutch again then shift into gear. The reason it came up is because someone thought that with my having troubles shifting into 2nd under load I should try to double clutch to help get it in gear. In reality it would be faster and easier to just keep the clutch down until the damn stick went in. Unless of course it just simply won't let it in in which case you can try a double clutch to see if it helps. Even Sport Compact Car talks about it. They basically say it's only necessary when the synchros are worn out or if you're trying to engage into 1st gear at speed.

My big gripe with the car is the damn gearbox.
Cause the car wasn't designed to be a drag car. The gear box is very tight and the fact that you burned the disc once is an indication that it will progressively get worse if you are careful.

If you want to learn how to shift then get an old car and beat the hell outta that, cause you don't want to find out the hard way how much it's going to cost to rebuild your trans and get a new flywheel.

FYI - to properly launch an AWD car with a turbo is to get the rpms steady @ your launch then slip the clutch instead of dumping it. Once it starts to roll then release the clutch. Don't worry about boost. It will come on instantly. If you want boost at launch then inject CO2 into the system and that will spool the turbo with boost. WARNING: your clutch won't like you much and the gear box will eventually get very sloppy. Especially if you're very hard on the gear changes.

Thanks for that description of double clutching! Ya, I can't see why anyone would want to do that if their synchros are working properly.

Someone also mentioned keeping the gas pedal to the floor the whole way down the strip even when shifting, how can you do that and not bump off of the rev limiter? I know you'd have to shift real fast, but I wouldn't think you could shift fast enough before the engine would bounce off the limiter--I tried it once bascially on accident and couldn't get it into gear before the rpms were to high and hit the rev limiter. When I'm doing a full throttle run, I just take my foot most of the way off the gas and shift like normal, but of course doing it as fast as possible

Power shifting or speed shifting. I'm pretty sure it's power shifting but some refer to it as speed shifting. I don't do it through every gear usually just from 3rd to 4th or 2nd to 3rd sometimes. You basically want to shift a few hundred rpms sooner. When you get it down you'll notice some higher traps and you'll feel better progression or a constant speed through your shifts. I shift pretty fast which is why I'm having a problem with this gear box. I'll get it down though.

were all your runs with or without the IC spray on. If so Manual or auto. ANy difference on or off if so.

I'm really not sure when it's activating in auto but I left it in auto the whole time. I'm positive it's working though cuz I checked my reservoir today and it's close to empty

BTW just so everyone knows the reservoir in the trunk is NOT for the IC spray. Don't look at that thinking you're full. There's a fluid res. in the engine bay in front of the battery that's for your IC spray. I checked it today and it's almost empty after some hard road driving and a day at the track. I guess it's working.

Yeah, I would say shift sooner, don't take it to redline, you are not optimizing boost then, shift at the top of the boost curve should net you better times. Not to mention close to redline the synchros may not be as efficient.

Max boost is at what? 4500 RPM? So, you're telling him to shift at 4500 RPM? Should he do this while double clutching? You're just a wealth of information aren't you... Take your Fast and the Furious DVD and throw it out the window.
