Default 1999 t/a 186,000 miles

So today i went and dynoed my new t/a. I just bought it for $4500 in mint condition minus the miles it has. I only put a lid and free mods and it put down 316.38hp and 331.56tq on a mustang dyno. Thought that was excellent considering the miles it has, 186,000 to be exact. So for everyone thats making less than 300rwhp there must be something really wrong

Those are some high numbers for a mustang dyno! Even if that car only had 10k miles.

A4 or M6?

Also, a Mustang Dyno can be calibrated to read correctly, one cannot always assume it reads lower.

Does it happen often, yes, but there is a reason why, generic calibration figures.

If a A4, those are STOUT #'s

If a M6, those are about average but still good since you have not quite as good as a intake as a 01-02 car would have.

I agree with you except for the highlighted statement. Close to 200,000 miles on a lid / LS1 intake car? Those are damn good numbers even IF the mustang dyno is calibrated to read the same as a dynojet.

99's have a smaller cam (bad), 853 heads (bad) , and an LS1 intake (bad), regardless of tranny, those are STOUT numbers.

Those are damn good numbers for a Mustang. Be careful though because that's why some people prefer dynojet's over mustangs because on a mustang you can reduce the inertial weight of the drum to adjust horsepower figures. If you get it out to the track let us know how it runs.

But all that aside, congrats on the new car! I love how with these cars, you can always find one in your price range if you look hard enough.

Like i said this thing only has a lid. No tune or anything. Funny thing was though was the car had a granatelli mass on it so i bought a new stock one and tested back to back. it made 312 with the gmaf. Then i put the stock one in and it made 306. Then descreened it and no kidding it then put down 316 with a perfect air fuel. then we pulled the air filter and it lost power. I think 2hp. The track opens up tommorrow after getting new concrete laid down so ill know then. Hopefully the new surface will hook. It is however an
M6 but i still think thats very stout for a 99 with the miles it has through a very tight set up new rear end with 3.73's

Well eitheir way i know my cam is a smaller cam but i thought the 01-02 got even smaller cams due to the lack of egr. Also i thought the 853's were still better than the 98 castings. Oh well im happy ,in time those things will all be replaced. I needed a good baseline before i started.

Milage is not a sole determination of how much power a call will make, its how the milage is put on.

https://ls1tech.com/forums/showpost....80&postcount=2

Read 1998 #14
Read 1999 # 6
Read 2001 # 4

https://ls1tech.com/forums/showpost....81&postcount=3 for reference on how much differen 01-02 were compared to 98-2000.

Now he does have a MAF that the car is used to thats why it showed a gained compared to a stocker. So he has a MAF and a Lid which would show some sort of gain.

https://ls1tech.com/forums/showpost....84&postcount=6 Cam Specs.

My car and a few others here, locally put down around 323-326 rwhp m6/10 bolt set up w/ a LID only, Mine did 324 rwhp 347 rwtq w/ 30k on the odom.

Had he tossed a LS6 intake id think he would be much closer to my # and thats still including the MAF upgrade.

For the milage its impressive but still about average given the year but then again. I car ran in 6th gear free way cruiser vs a dead stop pavement thrasher are 2 different ways to put milage on a car, regardless of the year, the make, and the model.

What I was trying to get across is the fact that its very strong for what it is. 853's are slightly better than the 806's, but still aren't that great (I had 806's on my old car). Its a really good base line.
