Nice car! That looks exactly like mine did a few years back...sigh.
Seriously though my 12A ran about 116 mph and that was it.
Very noisy and a little squirrely at that speed.

 

end of 4th gear for me is 114MPH - 115MPH.
Didn't really have the ***** to go much faster. I don't have an air-dam yet and the car was quite loose feeling, and I bet it was about to take off into orbit. Mazda says 123MPH top, I'll believe them.

Yeah I'm figuring around 120-125....

 

i've had my old gslse up to 135-138(speedo stopped), but it wasn't stock. the fi was scrapped for a dellorto 48 sidedraft. i probably could've hit 140. if i remember right, the previous owner had ported it( or at least ported the exhaust) , but sold it to me with a 1.5 inch exhaust: headers to cat to glass pack to muff. what a dork! he butchered a perfectly good RB streetport system cuz he was afraid of selling a car without a cat. funny thing is, nobody checks emissions in that state. i don't know if any of this helps, seeing as it wasn't stock, but hey, i'm bored and feel like typing. and yes, the car is squirrley going that fast. i won't do it again without an airdam.

 

It was 115 when I first got the car. 12A. I might try going that fast once a get a new stearing box.

 

I got to 210 km/h but i think that my speedo has about a 2% error (smaller tires)

 

12A piece of ****, no areodynamic upgrades...122ish...

 

Took it up to about 225 kph or 140 mph. I'm not sure what the top speed is since I ran out of road but it was still accelerating. With lowered springs and Konis the car felt suprisingly stable.

 

I have only taken my car to 170 kph or 106 mph havn't bothered to go any faster yet.

Revhead: what type of carter pump do you have i got my carby moded now it run out of fuel about 6500rpm. I wast told to get a carter rollercell i think. Does it look like an EFI fuel pump?

 

i estimate 130 mph.5th gear at about 6700 rpm racing a bmw 850 il.i'm sure he could've beat me but not before his lane ended so i'll say smoked that one.12a street ported,tokico struts & shocks,lowered 2",custom 2 1/2" exhaust,holley 650,R/B intake & header,holley fuel pump & regulator set at 7 psi(i think).185/60/13 tires and a 3.96 rear end(i was told).

 

madaz7, the fuel pump I'm using is the Carter 7 psi unit. It's a good pump. Easy to install and flows more than enough for any 12a. BTW, who modded your carby and what sort of power are you making?

 

I have had mine over 140 while I was living in Germany. Gotta love the Autobahn! Might of had a little more, but was running a large whale tail style wing at the time and it was like an airbrake.

 

REVHEAD: A Guy called Chris Greives (not sure if that how his last name is spelt). PRP's rotary performance is what he calls himself, he is also an auto electrican.

he is well know around the sunshine coast for his work with 4 cylinders and rotary's he also built my engine, i dont know what kind of power my engines making, i havnt had it on the dyno yet

 

well i have had both my current 7's to the speedo's limits. my 81 (mods listed below) had a 83 speedo and i had lots of pedal left@130. i just did 130 in my l.e 2 days ago... all this is acourding to the speedo being right

 

I just recently became a member of this site, and I have a some questions maybe some of you guys could answer. I own a 85' se, and I was wondering what I could do to improve the performance of my car. Its not completely stock, but I need some more suggestions as to what I could do to receive more Hp or just some general tips. Here is what I have done so far:

- I Removed all emission control systems and al catalytic converters. All that’s left is a straight pipe to the muffler. ( no header/ performance muffler due to unavailable funds.)
- I added a Racing Beat duel alternator pulley. And new pulley belts.
- I removed all sound guards/ installations and Tar from the floor.
- I removed all air conditioning components
- I added a oil over air cooler
- I put in 4 new TOKICO shocks straight from Japan.( Non adjustable but still work great)
- I have NGK spark plugs from a 3rd gen being used.( Witch work Great!!)
- I removed the black funnel and made a custom 2nd opening to the carburetor
- I have a custom stabilizer and torque bar mounted.
- K&N air filter.
- I removed the Air pump ( 1st thing to go)
- I added a performance pressure plate.
- I also lowered the car a bit to cut some air resistance.
- I added a light weight aftermarket wing to the rear for better down force( much nicer feeling when taking the on ramps :P )
- I am currently using Mobil 1 Full synthetic oil ( 10w30 for this time of year)

this all I can think of at the moment. If any one has any more suggestions I would love to hear them. Some considerations im still considering very much so are:
- electric fans
-MSD ignition boxes
- RB Header/Dyno muffler.
- electric water pump.?
- reposition of the battery for better handling.
