Just did these today at 19psi car made 353.4hp and 322.6 tq on the second run the car wouldn't build boost and the A/F was not right so I didn't go again. Looking the car over and hour later found that it blew a vaccum line off the intake manifold and was loosing boost.

So, I'll have to get another run to 24psi to know the limits. Car is crazy fast:evilgrin: :evilgrin: :evilgrin:

Thanks Orange and Supersnail again for a job well done.:hump:

Oh, yeah this is with VCT

Built short block at 9.2:1 CR, with a ported head, stock cams, shimmed springs for more seat pressure, 42s, ported JRSC supercharger, port matched intake, 180 thermostat, and ORP. I am guessing the car has the BBK as well, since it's got a blue pulley. Has a P-MAS MAF with cone filter.


Dyno graph is below. As you can see, SAE numbers are 214/164. You can see how well the porting is, because it's still going up in hp even at 7500 rpms. I set the A/F at about 11.7 all the way across, and timing is 19 total at WOT. Now normally I tune non-I/C blower cars at about 16 total, but in searching the forums it seems that these cars can take a little more with a lower CR piston setup. The previous tune (which was on the stock motor) was actually seeing 26 total, and I felt that was way too much. So I was shooting for about 19-20 total and it seemed to like it.

Boost hits just about 8 psi, which I figure is right for the BBK with a ported head, since the porting will drop your boost about 2 psi.

I was hoping for more power, but after thinking about it and looking at other SVTF JRSC dyno sheets (stock and built), I think my numbers seems pretty good. A stock SVT has more compression ratio and the BBK usually makes 10 psi with a stock head, so my setup is giving up some hp from less boost and less CR, but yet makes the same power as a car with more boost and CR. I could add more boost to it and easily get to the 250whp range, but since it's a DD and I really don't go WOT often, I don't see the need (right now).

The dark red run was 15psi.

The blue run was 18psi but cut short by me not raising the boost cut on my EBC.

The red run was on the same boost as the blue just to confirm any doubts!

All runs were made on a Dyno Jet 224x and on 93 octane!

Here are some comparisons for you, Stock, Wastegate spring (about 14psi), Pump Gas (23.5 psi) and Race Gas (29psi).

Clutch was slipping but we still managed a some what decent chart. When the clutch didn't slip peak tq was closer to 4k on the higher hp pulls

Race gas 110 octane 29 psi 16 deg timing

wtq is about 450
