yeah, tonight was definatly a weeeeeeee night.

ok, goto the track, I am runing between a 15.1-15.2 for like 5 runs most having a .66 r/t.

by now the line is getting really long, and they announce the sport compact car bracekt racing. I figure that I could get a lot more runs in if I bracket raced. plus, the r/t had been pretty good so i decided to go ahead and do it. first qualifing run, 15.2, 2nd qualifing run 15.11. So I figured I would dial in a 15.0. That would give me a little leeway and if I broke out I would be so happy it wouldnt matter.

1st eliminatioin run- BROKE OUT!!!! heck ya!!! 14.8 @ 93.19. I went ahead and shifted later on that run. normaly I shift right at 7k b/c after that there was very little power and previously buy shifting after 7k my times would be .2-.3 slower. well I shifted at 7500 and my time droped!!! whaaaooo!!! after last weekends free mods I gained power past 7k, yea!

I am sure someone will post about how slow a 14.8, and yes i am VERY aware of that. but give me a break, not bad for 1.3L na with very minamal real mods.

r/t- .669
60'- 2.208
330-6.246
1/8- 9.563
mph-73.74
1000-12.449
1/4-14.860
mph-93.19

oh, and btw, this was all done with a broken tranny and driveshaft and a discount auto parts clutch that is slipping slightly when I shift.

The best part of the night was I made 6 runs and didnt break anything!!! hahahaah

cant wait till after Christmas when I get all the new stuff in!!

oh, and what do you guys think of the times? the 60' and such. be burtal

 

why does evryone run good numbers and i run 16.8 with mods..****

If i recall correctly, 14.9 is a series 4 turbo II qtr mile.... I'd say a 14.8 is a damn nice time for an na, especially with no serious mods... thats what I hope to be running one day, high 14's


Nice run!

I feel your pain, I too, drive a convertible.

Anyway, about those other times.

14.8 is not slow at all for an n/a, it's actually very very quick. Most people would question it. I could go either way. If you claimed that to me in person I would request a time-slip.

Congratulations though, you've got a really quick car for what it is.

 

Your times look pretty good, but I think you could get a little better on the launch. How was your launch? I pulled a 2.3 60 ft time spinning my bald 205/60 R15 tires halfway through 1st.

Ive been anxious to get back to the track, but I dont know if my clutch is up to the challenge. I have better tires now, and Im afraid the clutch will only slip more.

Want another cheap upgrade that gives A LOT of power? Port your intake manifold. I gained as much from that as from the headers/midpipes. A word of warning though, get a set of TII injectors if you do this, maybe a TII fuel pump too. I have a TII pump and secondaries, and Im running very lean. PM me for details.

Current mod list:
cone filter
TB mod
ported intake manifold
RB dual outlet headers-->straight pipes (true dual exhaust)
all emissions removed, including air pump
6 port sleeves removed
electric fan
UD pulleys, main and alternator
TII fuel pump and 550 cc secondaries
A/c and p/s removed
Crane Hi-6
NGK plug wires
crush washers removed from sprak plugs(brings the spark closer
to the chamber, and also slightly raises compression)
timing advanced
some weight reduction...~2600 lbs
makes power all the way to the rev limiter...8600 rpm

 

Porting the intake manifold helps that much? Even with the tiny little bottlecap pinhole at the air filter?

 

Congratulations on a fantastic run, you make us FC owners proud.

 

Here in FL when it get to around the mid 60's and there is zero humidity my car runs awesome. You gotta love sea level! It's nature's nitrous!

BTW that car has to be loud as hell with just a N1 and a header!

 

Hey, 14.8 is GREAT time for an NA. I'm really not into drag racing myself, but I'm still curious what I can run. My clutch isn't up to the job right now though, when I get it replaced with an ACT hopefully soon I'm gonna take mine to PIR on a Friday and see what I can run. I'd be happy with a 15.0

 

oh, and I remembered a few more mods, the airpump is removed, the TB mod done, and kyb agx's in the rear. and also the primary and secondary thottle plates now open at the same time. not sure if this really helps or not, but how it is set up stock the secondary plates never go to a completly horizontal position. so, thats why I did that, kinda makes the car hard to drive, but i got used to it and can drive around it so it doenst bother me. As for porting the intake I assume you mean the dynamic chamber, well, I am making a custom part to replace the dynamic chamber so that should do better than porting it thanks for the idea though! as for the cold air intake, i think i should explain that a little better too:

ok, instead of the intake taking a 90degree turn and the ducting leading down by the headlight. I cut the plastic 90 degree piece that comes off the TB and fiberglassed a round peice to that, and conncected the AFM to that, and the filter on the end of the AFM. so my intake has no turns in it whatsoever. the filter is at a 90 degree angel to the fender. so my filter is up right next to the firewall. to get some cold air in there i have a hole cut in the hood, a very small scoop will eventualy go in there, but currently its just a whole in the hood. I wish i had a picture, but i dotn have a digital camera.

 

heres the timeslip

 

I did that too with the throttle plates. It is kinda annoying trying to hold a constant low speed in a low gear, but other than thats, its not too bad.

As fas as porting the intake manifold, the runners narrow at the flanges where the pieces bolt together. Some places narrow as much as 30-40%. You look at the manifold before and after porting and wonder that the hell Mazda was thinking when they designed the manifold. The gains were very noticable. As noticable as my dual oputlet headers/true dual exhaust.

 

cool, belive me, any porting that can be done on the manfiolds will be done! that sounds like a BIG power gain! haha, I know exactly what you mean about not being able to hold a constant speed. but its pretty easy to drive around so I dont mind it much.

oh, and someone mentioned that the car must be loud, hehe, yeah it is, but its not really to bad. with out the silencer in it will set car alarms off, but as long as you dont lay into it, its really not that bad. its a nice and low sound to. with the silencer in its fairly quiet, not loud at all, but then agian, with the silencer in its really quite slow.

ive been working on the 60' times. part of it is my car not being set up right, b/c of me. I have broken 2 diff mounts at the track, and those things are a pain to replace! so I always run the rear suspension real stiff when i go to the track so that i dont get to much wheel hop. I was running the agx's on 7. i know that kills the whole weight transfer thing, but oh well, at least i didnt break anything

 

You have a vert, nuff said :p

 

Just curious, do you get bad wheel hop with the rear suspension as stiff as you use? From everything Ive read about FC's and wheel hop, to stiff of a rear suspension or worn shocks is what causes it. I seriously doubt your shocks are worn out, so you would get a better launch with the rear set at the softest. You shoudlnt get any wheel hop with that.

How much wheel spin are you getting, if any? You might want to try different launch RPM's someday on a back road or something.
