We went to the MIGPC Dyno day today. It was $35 for the first two pulls, and $20 for two additional pulls after that if there was time at the end to get the pulls in. They told us ahead of time to give our guesses for horsepower. The winner of this contest (the one closest to their guess without going over it) got a $100 PFYC.com gift certificate. The guess only counts for your 1st pull. If you guess a 270 and pull a 258 the first pull, but a 268 the second pull, the 258 is the only one that mattered.

The guesses for our GP'* were:

GTP: 315whp
TGP: 200whp
STE: 178whp

First let me tell you that the operator was having trouble getting the RPM readings for the cars, so the torque was way inaccurate and i won't even list it here.

The GTP went first out of our 3 GP'*. It pulled 304.9whp on the first pull, then it pulled like 301whp or something (I can't remember for sure). We were fairly happy about this as it was the highest pull of the day at that point, but dissapointed that it didn't hit the goal.

I then pulled in with my STE and started. It pulled 182whp. I was very suprised because I guess 178 so that it would be really high and I wouldn't break out. 182whp puts it at 227.5 crank hp. Pretty good for a 14 year old engine that was rated at 205hp stock and just has a K&N, Magnaflows, and no cat. My second pull was something like 176whp because my intercooler was heat soaked. The killer is that for some reason car was only getting about 6psi boost, and it usually gets 8-8.5.

After this I went out and got in the TGP and drove it around. If the car isn't warmed up it won't let you get full boost to try to prevent killing the turbo because of the chip that is in it. So I took it out and warmed up the engine so it would get full boost. Then we put that on the dyno and it pulled around 192whp (can't remebmer the exact number). I was very shocked with this because the car is very noticably quicker than mine and it only pulled 10 more horsepower, and it has a chip that should've given it a 40hp advantage since it is almost identical in every other aspect.

I would post the dyno sheets but 60 cars were dynoed in less than 8 hours, so the guy didn't have the time or the ink to print out all those sheets. He saved them all to disk and the MIGPC club president it supposed to email them to everyone.

So anyways, after we ran all the cars we went home (4 miles from the dyno) and put the exhaust back on the GTP (took it off for the dyno hoping for more power). We had the 2.6" pulley on and the timing turned up to 20 degrees. (as high as we could turn it up with the programming in the PCM) The car was getting no KR at all and could've easily had another 4 or 5 degrees of timing. After everyone had dynoed their first two pulls we pulled the GTP back in and dynoed it with the exhaust on. The first pull it pulled something like a 298whp. We were disapointed, but then it pulled a 302 on the next pull and we were more impressed. This was within 3hp of the best pull with the exhaust off, we just had to try again. One of the ZZP guys hooked up a tech 2 and worked a little magic. It then pulled a 315.6whp. We were amazed, along with many others there, including Zooomer. This is the highest stock cam L67 dyno ever by quite a bit.

The GTP pulled the most horsepower of any GP there, and the 2nd most of any car there. The next closest one pulled 301.8whp. 301.8whp is still very impressive. After all the GP'* got done, the few RWD cars dynoed. One of them dynoed more than the GTP (the Camaro SS) and it dynoed like 328 or so. The GTO dynoed 308whp, and the T/A dynoed 298. The Miata pulled an amazing 95.2whp!!! The other GTO didn't dyno because it was IDENTICAL to the one that dyno'ed except the seats were different (black w/blue inserts instead of just black). And yes, all cars are different, but the owner decided that it wasn't worth $35 to get numbers very similar to the other one.

So the final outcome of the day for our 3 GP'* was:

GTP: 315.6whp
TGP: 192whp (not sure of exact number)
STE: 182whp (not sure of exact number)

It was a very fun and interesting day to say the least. I wish we could've brought the SSEi but my mom is complaining about the tranny starting to act up (I think it was just an excuse so we wouldn't dyno it), and it needs some mini-afc work before it will run decent enough to even want to put it on a dyno and I didn't really feel like tuning another car today. I had my share of tuning cars today.

Sounds like a great day and you found sucess
Do you know what was tweaked by the teck2? Timing, fuel?

Impressive power out of your cars.
Power of a 5.7 L V8 out of a 3.8 L V6. You gotta love it.

Michegan must be a great place to live, if you're into cars like us.

Wondering about the TGP and STE. I bet the difference you feel is really more torque related than hp related.

Sounds like a hella fun day! And the GP was stunning!

I was VERY fun, and I was suprised and impressed by a lot of peoples numbers, can't wait until the next dyno day at the end of year. (but mostly because I should be putting out more power than some of the GTP'* at that point) The difference in power between the STE & TGP is almost definately horsepower. I know my STE has significantly more low end torque than the TGP for some reason, because that I can feel, but above about 30mph the TGP slaughters the STE, as it should becuase of what it has done to it. With it getting 4psi more boost and having all the other mods basically identical to the STE I just don't understand why it puts out that little amount more. Thats only 12 crank horsepower. My guess is the TGP wasn't getting full boost because the engine hadn't been running long enough (another stupid turbo protection programmed in the chip), but I'm not sure. Oh well.

I know what they did, but I can't really tell anyone. It is a mod that is currently in its testing stages. And it wasn't timing or fuel.

Shawn

Awwwww.....come on, quit teasing us...

Not even a hint.... :P

Bummer, I hope the mod is avail to all by this summer

Not Torque Management?
