('93-'01) 1/4 mile w/cobb intake vs. JC intake, proof

scootr · 05-10-2001, 12:06 AM

Here is my slip, I should have got a 15.8 but I let off a little so I did not go under my dial-in.
<IMG SRC="http://a1060.g.akamai.net/f/1060/597/30minutes/www.zing.com/picture/p2f15e01e7a7f5f78e969ad64156ee5b9/fe8a03ea.jpg" border=0>
This is with the Cobb intake and I could only get a 16.18 with the JC intake. I am still a little dissapointed with my time but I think it is my Brospeed exhaust that is not doing much more than stock. I think I am going to go with a stromung and headers or something. I do not understand how Mcguyver got 15.3 with a 98' that has JC intake, ACT clutch and exhaust. I launched at 4000 without dumping the clutch and I shift good. So what is the deal? I was hoping for at least mid 15s. Hey Kevin Thomas you can add this to the 1/4 mile registry even though it is not much.

hmmm. Spunky pulled a 15.4 at the drags in FL with GanzFlow as the only mod, and 15.08 with GanzFlow and 200 lbs of junk ripped out of his car...

ImprezaRS dot com · 05-10-2001, 09:12 AM

It is actually a lot harder to get great times out of a car at the drags than people think. Lot's of people never get their stock RS's out of the 16's.

The fact that you dropped that much time consistently with an intake change says a lot for the change in mods. And, Spunky was pulling 15.8's with a stock car. Maybe you did get the slow one.

Get a lightweight pulley (I have an N1 on my car and like 'em so much I am gonna sell 'em), do the stromung and midpipe (I also sell

) or a Borla header and catback. These are all bolt-ons. Then when you get permission to go into the motor, maybe a lightweght flywheel or cam. Then she'll rock and roll. Consider a high flow fuel pump or run 40-45 psi fuel pressure when you do all that.

If 18" wheels you are considering are a lot heavier, when you get those they will slow you down...

pics of the cobb intake?

goose · 05-10-2001, 09:47 AM

there are about a gazillion different variables to take into account if you're wondering why your car isn't as fast as someone else's similarly modded car- gas, tires, ambient conditions, weight, elevation, etc. etc. etc.

mcgyver · 05-10-2001, 10:06 AM

Scootr,

At least it got better

* Nice reaction time*

That 15.3 was my Best, haven't repeated it since, but I can run 15.6's consistently.

There's definately variables:

Tires: 205/50 R16
Clutch: ACT
Flywheel: 14.9lbs. (Primmitive)
Exhaust: Cat-back 2.5" w/Magna-flow
Intake: JC Sports
Shifter: Homemade short-shifter
Weight: I've removed my spare & jack, took out my 12" sub (45lbs.)
-Also I only weigh around 130lbs.

That's all I can think of right now
-Adam

NateDogg · 05-11-2001, 07:40 AM

i run 15.6 STOCK, to get the car to drag race well you need to launch it properly, let the clutch out a little rev to 5 grand and let the clutch go, works great and does really hurt anything

RidinLow · 05-11-2001, 08:22 AM

Yes, you're right, it does really hurt everything.

Tkacik · 05-11-2001, 09:47 AM

Poor little drivetrain........I havent ever hurt my baby like that

"I'm sorry......really I am.......No please.....enough with the clutch chattering.....I'm sorry I'll never do it again" (actual conversation had with car, sad I know)

SUBYRS710 · 05-11-2001, 11:12 AM

I ran a 15.4 last night with rallipsec intake, ur pulley, apexi n1 exhaust, motor & tranny mounts, but that was before a piece of *($&#@*@(@( ***** MUSTINK racing beside me fell apart and came into my lane, causing me to run the stupid pieces over and get a flat tire

God i hate RUSTANGS!!!!

Kevin Thomas · 05-11-2001, 04:23 PM

scootr,

I can't add the time just yet, my service provider is having problems with the webspace. Maybe later tonight. Don't feel bad about the times. Remember, I came from an 18.2-18.3 stock. Added intake, exhaust and pulley hoping to break into the 16's. Lol! Boy did I have a lot to learn. Only managed to bring my times down to the mid 17's. Almost 1k spent between mods, shipping and labor only to drop from 18.2's to mid 17's. That hurts! I feel your pain my brotha. Hehe!

BTW: What track where you racing at?

SUBYRS710,
Lol! And they say the imports are unreliable at the track. Just be glad it wasn't a rotary going to pieces. They look really scary popping that wheeling beside or behind you and dancing up the track. I have to watch out for this bracket racing some of those 10-13 second ones. One of the scariest times I had at the track was one night during the Gamblers races at Atco Raceway. I was trying my hand at bracket racing against some dragsters. I was running in the 17 second range and that car came by me at (Getting timeslip of that night....found it) 170.32mph. I ran a 17.660@76.00mph to his 7.824@170.32mph. I had a reaction time of .534 to his .503 but he broke out by running a 7.82 to his 7.84 dial-in. I sent him and his family home on a trailer.

It was nervous watching that dragster coming up on me so fast though.
And ya'll say drag racing ain't for Scoobies.

mcgyver · 05-11-2001, 05:52 PM

Scootr was @ Sears Point Raceway, like me

I might make it next week, hopefully to improve, but I agree, the driver makes most of all the difference. I'm still learning because my times can differ up to .4 sec. on the same night

Must work on being consistent, I keep telling myself

-Adam

Patrick L · 05-11-2001, 07:43 PM

I got a 15.4 in my N/A MY00 RS.
Back when I had a newer clutch.

That's insane of the track officials to even let your car go down the track with a 7 second monster. What if he lost control? You'd be dead. Bracket racing or not, they shouldn't allow mismatched cars like that on the track simultaneously. I know they don't ever run motorcycles against cars.

*Be careful!*

is yours an auto?

direwlf · 05-11-2001, 08:26 PM

That badly mismatched isn't bad. If a guy running 17s screws up in the lane beside you and hits you, you are going to be just as hurt. Less speed but more mass, as opposed to less mass and more speed. Six of one, half a dozen of the other. Altitude is probably going to be one of the biggest factors in your et. And, congrats on the killer reaction time.
