It was a long day at the dyno Saturday. I had the first tuning done on my turbo with a stock block.
Scott Beer is working with Dagostinoracing.com on Kean road, right off the Griffin road exit on the turnpike for all you SFL boys who are interested.
10 dyno pulls and 12-15 road pulls later he settled on about 420 rwhp and torque at about 7.5 psi. I do not have a dyno sheet as we did the final tuning on the street. The turbo was very hard to tune as the electronic boost controller has many features and reacts very quickly. The actual boost setting is not in psi, but a numeric scale of 0-99. My turbo was barely breathing hard at the low end of it’s capabilities, so we had a hard time controlling it. In addition there are Overboost settings and waste gate settings to program in and sensitivity to prolong the boost through the rpm range. At one point we hit 12 psi. The car made 500 hp and climbing at 5000 rpm before he shut it down.
The controller reacts so quickly that when the car shifted on the street under load there was some detonation. Scott figured it out and it is fine now, but I have to get my valvebody installed and a BAP installed and go back for a better adjustment.
Just some general commenta, the power comes on real smooth but hits hard. The car is almost a sleeper as all you can hear is a slight whistle sometimes over the aftermarket exhaust, no blower whine and the wastegate is vented to the exhaust. The tune is fine on a single GT-40 pump.
