The car defintley pulls hard all the way to 100, and it really sucks when you pass the beams and like not even a MS later you're at 100, I'm thinking about short shifting 3rd a little bit in order to stay in the power band of fourth, or even ride 3rd out just a bit longer (8100 RPM, it does pull hard past 8k, I found out on accident).

The wheel hop was so bad, that my hatch popped open when spinning the tires past the water box so I didn't have any water on them.

 

why are you in the waterbox?
you wont hit 13s if you are only trapping 91-94mph.
it is your first time at the track, why are you arguing?

 

We don't have an option of going around the water box...

I'm not saying I'm going to hit 13's, I'm saying the owner of the Drag Track was sitting there telling me that every run my trap speed was going up by almost a full mph, and I didn't get but three runs in because all of the motorcycles kept cycling through in front of the cars.

I'm not arguing anything, you're taking it that way, the whole point of my post was to indicate that my trap speed went up every run, I haven't had a chance to get the full power out of the car yet with my limited amount of runs, it rained.

 

haha,

I was in the crowd watching him.

the little kids were laughing becuase his hatch popped open.,,,,,,,,,,,,,,,,,

of course so was I.

but he did have lotta wheel hop.

I dont think he slid that far down the line......

 

You're pretty close to being on-par with the power your cars making, all that you really have left to do is to take advantage of the launch to cut the times down, practicing launching and keeping the hop to a minimum and tire spin down will provide you the best improvement. Did you drop your tire pressure at all? I would probably suggest you keep them up to avoid making the hop even worse, and then make the best of the grip you can get from the tires you've got.

 

I did just a little bit, which was probbaly stupid but dunno.

I do have a new Bridgestone Potenza on there now, the day after the track my tire went flat and no one would repair it...

 

If you had 16s I'd give you my RE92 sitting in the back of my WRX to have a pair!

 

Those were rated HORRIBLY at Tire Rack, I guess that's why you would give them to me!

 

the hatch popped open??? wow be careful man...whell hop = bad...

 

Who rated RE92's terribly? They're not too bad if you can get them cheap, they're not good for their price however (which is why most people don't like them). But, they came stock on the WRX and were replaced, so I have no use for em!

 

Yeah that's why it would bog down on launch, I was only able to launch at around 3,500 - 4,000 RPM...on the streets I usually launch at around 5500 RPM and it's perfect launch every time and I'll out run most stuff from 0-70 MPH easily but after that it fades (tuning issue).

 

If you can cut the 60' to 2.1, the most time you can gain from that cut is roughly .5 sec. For every tenth you cut in the 60', its two tenths off at the end. So you are looking at 14.2ish. Not a bad time though.

 

I'll be more than happy with a 14.2 because in the end, that's all I really wanted.

BUT I will say this, the car's highly untunned right now (I can't even tell the fuel pressure, UPS is being slow with my package), no idea on AF/R either, stock injectors the only real things I've done have been the FD Fuel Pump and Racing Beat TII Cat Back...the pace crap header I don't consider any kind of improvment over stock except a noise maker.

 

If it hasn't blown up yet, then the only thing you can be doing is running rich, so larger injectors won't do anything for you unless you swap pullies again. You should try to get some wideband time in and dial it in somewhat.

 

Actually, the way it makes more power right now is with the AFPR with the rising boost/fuel feature which means it puts a huge strain on the fuel pump where it can't flow enough...Atkins has made a HP improvment every time they went to bigger injectors.

A TII makes more power when you up the injector size, why wouldn't a supercharged?

 

Are you serious? So if a guy with a stock TII puts on 720cc injectors and doesn't touch anything else, he's going to have more power? They should all just put on 4x1600cc injectors then since going up in injector size means more hp by itself

Bigger injectors without changing ANYTHING, including boost, wont add power. You'd need something to tune it with and up the boost to do so. Changing injectors only and not touching anything else wont do anything except possibly save yourself from detonation if you were borderline to begin with.

 

Dunno, I'm still learning this is why I ask questions...

I'll just throw the smaller pulley on there when I up the injector size and go to 10-12 PSI of boost then...

 

Get a wideband and something to control the fuel with also. Then either get some dyno time, or try to tune on the street but I suggest dyno, much easier.

 

That's what I was planning to do, was get a wide band...BDC Motorsports will be tunning it very soon (as soon as I get the money) along with a ported throttle body.

 

Continuing from what dDub said, pretty much if your fuel system is strained right now and can't keep up with the ammount of air you have, and it hasn't blown up yet, when you put larger injectors on you'll lose power from running richer (and safer). As dDub said, just throwing fuel in won't make any more power (it'll make less), because you're not increasing the air volume with it. This is why I said you'll need to swap the pullies again to get more out of it. But, be pretty weary when you do swap pullies, as that pulley has given just about everybody troubles. Also unless you're running some stupidly high pressure on that FPR, it shouldn't be put any strain on your pump.

 

Hmm... This cliche' formula needs to be squashed, simply because it's logial conclusion is a 13b car (or go-cart) that weighs 300lbs and runs a 14 second quarter mile... Now, we all know that a 120whp go-cart would do the quarter a LOT faster than a 14 flat.

Even if that isn't a perfect example, it's easy to understand that power-to-weight is VERY significant, even if the results aren't initially obvious. So, if you can get your car down from 2800lbs to even 2500lbs--there will be a noticable difference, especially in a 'lower-torque' 13b... Case in point: Have you ever tried to show-off your Rx7 to one of your "huskier" friends?

 

cliche formulas suck

 

maybe i should ride with him since i weigh 200 pnds next time on 1 run. lol

see what differencce it makes.

 

Damn that car is a Cow i have a 88 stock na running 15.2 97.0 mph just racing beat headers and a nice sliping clutch

 

Haha, you're a liar. That wasn't even a good try. There's no way you're getting a trap that high on a stock NA, nonetheless at 15.2....
