Well I have some good news and some bad news. The car made some great power today. But the disk that I brought the dyno runs home on got corrupted somehow on just my files. It got all the other dyno runs, but everyone on my car got screwed. I will call the shop tomorrow and have them e-mail me the files. I will have them soon though...
Here is how it fared...
For yall who dont know I was dynoing the difference between the Link ECU and The TEC II on the exact same car, same dyno, and identical setup on car.
Best Link with EXACT SAME SETUP... 265 Uncorrected hp
Best TEC with EXACT SAME SETUP... 289 Uncorrected hp
Link Torque 216
TEC Torque 245 ( I think but I am not sure, but it was about 30ftlb.)
The TEC's Dyno chart was MUCH smoother than the link. The dyno operators noted how much smoother my car was on the dyno. It looked like a normal dyno chart, no spikes and jagged edges.. I got the A/F to about 11.5:1-12:1. EGT's were low and just around 1400. The Manifold did not glow as much this time. Last time it glowed very brightly. This time was just around the collector right before redline..
Here is where the good stuff comes in. I could of made more power on that setup (maybe broken 300, but I am not sure) but the turbo that was on there finally blew the rear oil seal. It looked like a mosquito truck (i dont know if you yankee's know what that is :D It has been going for a while. I happened to have my nice big turbo sitting there. We decided to swap the turbo. We swapped the turbo and let it idle for about 15min to break it in a little bit. I know this was too little but I was short on time. First pull on the same ignition map and 6% more fuel across the zones we ran it with the Boost controller off. At 7lb of boost it made 230whp. The link had made 207 with the other turbo. This made me very happy as I had yet to turn the boost up. We did a 3rd gear pull to see how A/F was. 6% was perfect. 11.5:1 across the boosted zones. We did a 4th gear pull and pulled 301. Added a little timing and got to 303 with no knock. 2hp was not worth 1.5* of timing so I pulled it back out. We then turned the boost to about 16.5 (was 15 before) and got 317hp and 291 ftlb of torque uncorrected This bigger turbo since much better suited to the motor made some serious mid rage power gains. In some spots close to 65ftlb of torque. It held the HP curve further. The HP curve kept on making power to redline, and could of made more power if we reved it to about 7500. We were only revving it to 7100.
The car is a BEAST on street now. Roll or stomp on it in first and you are instantly at fuel cut from wheel spin. Hit 2nd and hold on to the wheel as the car is jumping across lanes. Shift to 3rd and be careful because it is still getting loose in the back. 5th gear on the interstate is insane. Get on the gas at 4000 full boost before 4150. I haven't seen where I get full boost at by starting at 2000rpm, but I will later.
I have a feeling that I will be breaking more than trannies soon..... Torsen will be toast soon.
I will post the files somewhere if someone can give me some space, once I get them..
Both of the turbos today made more low end power than the Greddy :D
Ohh yea there are a few people I have to thank. My friend's Hassan, and Archie helped me out a lot today with the tuning, and telling me when enough is enough. Tom from www.lightningmotorsports.com was great as the dyno operator, and really helped me get the AF dialed in flat. Ric and Shiv both gave me pointers on how to tune the TEC, and some enthusiam on breaking 300whp.. Rob Cadle for the AWESOM specs on the turbo, and Louis for helping on the EH housing.
And Thanks to everyone on the List for all the help... Lets see what this thing will do at the track tomorrow night!!
