I took my '97 to Milan Dragway for the first time this year on Saturday. There were a number of changes in my setup from the end of last season: new, bigger DRs, skinnies on the front, battery relocated to the trunk, 100 lbs of weight removed, and a second nozzle added to the water/meth injection system. I had hoped for a very low 12 second run, or maybe even a high 11, but it was not to be. There was a 10-20 mph headwind, and the best I could do was nearly the same ET as the last time out, at 4 MPH slower trap speed. Best run of the day was a 12.44 at 110. The car ran 12.43 at 114 last October in similar weather (other than the head wind).

The good news is that most of the changes worked. Traction was very good with the ET Street Radials, delivering my best ever 60' time of 1.71. Handling with the narrow front wheels and tires was fine. Weight transfer was effective, and the car ran straight and true all the way down the strip. Plus, I humbled a couple of Mustangs, so that was fun.

But, the car seemed to be down on power just a bit. I assumed a retune would not be necessary with the second nozzle, since more flow would lower air inlet temperature and permit more timing in the existing tune. Looks like I need to go back for more timing.

1989superchicken,

My guess would be that the Mustang drivers were more surprised than angry!

One of the things I enjoy about taking the car to the dragstrip is that people come by to look it over because they aren't used to seeing MN12s there. Then after I make a few mid-12 passes, they express surprise about how (relatively) quick it is for a big car.

mikeB any idea on the air charge? this a very importeant factor, if you could get those numbers and please let me know, also this is another thing ive done for cars at the track with 2 bigger nozzles is lean them out 3-5 percent for the track only cause of the extra meth being injected seems to richen them up at wot but this can only be a track file, also you really need and aereoforce gauge or something to log the aircharge plays a big role and u can also monitor timing which would help tell us whats going on

RobertP,

I have a code scanner which I think will let me monitor air charge temp. I'll try it out after the rain passes through our area.

By the way, here is a video of one of Saturday's runs: http://www.youtube.com/watch?v=kYH_EVUbsGQ

Mike it sounds really good, also were is your intake air temp sensor, Ive found that for daily driving the sensor is better to be right above the blower outlet instead of in the runner at the track it don't matter cause u have cool off time

RobertP,

My air intake temp sensor is in the runner to cylinder #6.

I checked and found that my scanner cannot monitor air charge temperature.

Went back to Milan last evening with the single nozzle setup, and the car was slower. Hard to say whether, or how much, power was affected, because traction was not as good as it was on Saturday.

i really wish you lived closer if i could tune this car and play with timing i gurantee you i could get you in the 11s pretty easily its all in the timing, and air fuel got my new cams installed and Chung Came down and we toyed with the air fuel come to find out we had to lean it out 2 percent from the came change and ive got a new pulley that should be here thursday,

Mike give me a call if u still have my number we need to talk some more or PM me

MikeB you need to let me sell you and aeroforce scan gauge so you can see just hot the air charge is when you stage up to leave the line makes a big difference get up with me on it there build to order, ever supercharged obd2 car ive done has a gauge on it for that simple reason so we can moniter air charge and timing

RobertP,

I checked out the Aeroforce Interceptor gauges on their website. They are really cool! I would probably want the dual gauge setup with the splitter cord. Not sure whether I would add them to what I've already got (in A-pillar pods) or replace my existing voltmeter and trans temp gage (since both of those parameters can be monitored by one of the Interceptors). Either way, I won't have the money for them for a month or two.

What I can spend right now, I'm putting into a less restrictive air intake setup. After communicating with the tech guy at K&N Filters, I'm replacing the small filter on my MAC cold air system with a much larger cone filter which will flow about twice the CFM. Also working with a tubing shop in the area to make a larger diameter upper pipe to reduce restriction between the 90mm MAF and the 75mm TB. Then, of course, the car will need to be tuned again, which it needs anyway with the dual nozzle water/meth setup.

well the mac cold air ia a big restriction in that setup, plus Mike with that set up i beleive your gonna need to lean it out a little for the track running dual nozzles like 3-5 percent also i can do the dual gauge kits for 389 to your door me and gmaestro were talking about those the other night give me a call check your private messages and give me a call and ill give you the price on the boost sensor kit or any of the other stuff your after just let me know

That is a sweet car, glad to see that you are beating it up a little bit, it was nice meeting you at the Stoney Creek meet.

May be we all can meet at Milan and do some racing.....

Nativedetroiter,

I've never been afraid to drive that car hard at the strip, and it has (thankfully) never broken anything there. I do keep a low profile on the street, however. Its just too big, too red, and too loud to avoid unwanted attention!

Would love to see a Michigan Chapter outing to Milan for a Wednesday test-n-tune session. We could do some match racing, and show the Stangbangers that big cars need to be respected too.
