ATTS Drag -12.755@109mph
1 Attachment(s)
A local club runs an interesting series, in which the final event is a drag.
This year, I improved my times, by switching to a 99 head, and increasing the boost slightly. I still got left in the dust, mainly by the Subaru's and a few fast pony cars, that were running in the 11's..... Like most Miatas at the drags, I found launching with street tires to be a big challenge. I found that I obtained the best 60', by launching at low rpm's, allowing the rears to hook up, and then hoofing it. Here's an in car video. http://www.youtube.com/watch?v=J-wO2YopBW8 Here is the fastest time slip. Attachment 193301 My set up is not typical: A Thunderbird SC, Starion IC, GM 2x48TB, MS1, 2xMSD6A ignition, 1.8L etc. in a Mariner blue 1990, all optimized for autocross, on tiny Canadian parking lots. :crx: |
A better 60' then I have cut, so I wouldn't consider that too bad on street tires. How much power are you making? I cannot see any videos either btw. Good run!
|
nice runs! around 250whp im guessing?
|
Pics of your SC setup? I wish I could use first like that. Props on Driver Mod, lol.
|
Moar info please, like what power you are making and what tires/size you are running.

Hey congradulations, thats a good time. In for some pics of that hefty M90.

What rear end do you have Shifty McShortgear?
|
Nice. How much boost? Is that at Cayuga?

Ok, here is a rather busy underhood shot.
Attachment 193243 Starting from the upper left and going CCW. -red boxes are the MSD6A ignition driving stock 90 coils. -pressure regulator and valves for wi. -EV14 750cc injectors -expansion tank for coolant (rad has been lowered) -2 stage wi nozzles -no reroute, I'm using an 02 head gasket -8rib belt driving sc @ 2:1 -the blower. the throttle body is on the back of the sc. Air is routed thru an air cleaner under the fender at the bumper, up thru a hole in the inner fender to the back of the sc. What rear end do you have Shifty McShortgear? Is that at Cayuga? How much boost? |
Pretty neat car, and nice runs. Do you plan to further develop the motor with the set up you have?
|
Wow! Kudos to your setup, research, build, etc. Nice job and good luck!
|
Wowwww really cool idea and setup, get some radials at LEAST lol, I got some 22" slicks on 4x100 13s if you're feeling a trip to the states to borrow them haha
really cool, I like this... |

Thank you, for the positive comments!
The engine does have forged rods, ceramic coated pistons and a billet oil pump. My winter plans are to replace the intercooler (which is restrictive), fix up the exhaust and possibly do some head work. I would love to have some drag radials, but since I only run once per year, that is unlikely. How much time do you find they improve your ET by? Went to the dyno a little over a week ago and ended up with this. I retarded the timing slightly between run 8,9 and 10. Run 11 is with a restrictor in the piping leading to the intake manifold. Attachment 192714 Here's the data log of one of the runs. Megalogviewer pic If I get my act together, I may be able to replace the intercooler and get another base dyno run, before the snow hits. |
Damn that's a nice ass power/torque curve and 250 on a sc is impressive.
curve like that for a daily would be phenomenal. |
