A few weeks ago, I dynoed my HKS 2530 / Inconel Manifold super white Z at a local dyno shop in the Bay Area, just to see how much power she was making. My mods are: HKS 2530s, Specialty Z inconel manifolds, SZ old style downpipes and now testpipes, HKS turbo exhaust, 555 injectors, JWT dual pop, stock heads, stock cams, stock internals. I never have had the car dynoed or tuned since I upgraded to 2530's (late last year), and to say the least results were disappointing. I only made 309 rwhp with a Air Fuel ratio that was so rich it dropped off the page. Thats when I knew it was time to give Specialty Z a call.
Once the car was on the lift, Seb replaced the high flow cats, which were rattling incessantly and so clogged that the car wouldnt even rev past 3000 rpm and build any boost, with test pipes. Also there was a slight problem with the wastegates, which was diagnosed and fixed quickly.
We headed to the dyno in the afternoon, and driving in my Z, it felt like a different car. Throttle response and low end torque were excellent and I couldnt wait to get it on the dyno for Greg to make adjustments with the fuel.We made a number of runs, I scanned all the runs so here we go: 1st run: baseline run before any tuning
 . 2nd run, with SAFC adjustments and increased boost
 .
3rd run, with more adj and increase boost
 .
4th run with more of the same
 .
5th run with alcohol injection turned on, on all the other runs it was turned off. Interestingly, it didnt appear to create any horsepower on this run (i used a mixture of denatured alcohol and distilled water)
 .
6th run, going for all the marbles: 600 rwhp!!!
 .
Afterwards, Greg took me for a ride in my own car. Still on C16 and cranking up the boost to 1.85 bar, it is scary and i mean scary fast how fast this car feels on the street.
I was pleasantly suprised with the results of the dyno session. We used C16 race gas for all the runs. Pump gas figures (In Cali we have 91 octane so 15 psi would be the max i'd run on 91) for 15 psi seem low to me but i guess that only reinforces the fact that if you want high power you have to pay to play (run race gas). Overall i am very happy with the results and the tuning session. Greg and Seb really know their stuff when it comes to Z's, they live eat and breathe the Z32 and I want to thank them for their southern california hospitality as well as all the other people who were at the dyno yesterday. I also wanted to thank John from Exact Motorsports in Milpitas for dolng a great job in putting most of the car in its present incarnation together.
