2.8 pulley on a Ported blower. Dualpass, ZZP S3 Heat Exchanger, Option B tank, CAI, 4-2-1 header with 2.50 exhaust no cat. On the Dyno we were seeing just over 13psi.
It needs meth, and larger TB.

Thats it on the 2.8?!

No, low power. Based on the cars I've done pulls with and how I pulled on them I estimated I was making about that much without an exhaust. Of course that running about 10* of timing up top with a 12.2:1 afr.

I'm happy with the power after comparing to others. The cars that seem to be 240whp+ have cams and LS1 TB's. Also larger pulley's, and meth. So considering stock cams, TB, and no meth i'm pretty please. It has more with meth, and other supporting mods.

Agree completely. I bet the thing has great area under the curve though. Also have to consider engine redline, which i assume is in the 7k rpm neighborhood. This would put the blower in the 16k rpm neighborhood, where heat is a serious issue.
Yeah heat is an issue with the 2.8, I don't have a dual pass and my iat reads like 170 on an 80° day ayer a 3rd gear pull. But my iat reads 20° high based on my calibration checks.

We reved to 6600 on the dyno. I was pleased that the power curve was holding strong at that RPM. Will get the graph posted once I have a copy. Owner has it, waiting on him to get back to me in the next day or 2.
On the Dyno IAT's never got above 139 during a pull. Really pleased with the IAT's. They would climb after the pull to around 145-150, but as soon as the car was rolling they would drop down to around 121-125. On the street they are better, but still with the heat in Fl 90+ those are good IAT's for a 2.8.
I believe I left a little on the table it was tuned for 11.9, and I know the Eco liked leaner, but this car will be driving to Utah soon and after speaking with the owner we went for safety over all out power. So considering this is a good number for this car.

Mine do the same on 60 lb injector, map 1bar ! Fuel Trim not compensate (0,00% ) too, when idle AFR target for WOT

Cat over temp.

I don't have Cat and Oxygen sensor B2 are desactivate. I don't know if they can cause this idle richer and cancelled Fuel trim also

Cot is based on a ton of variables. My rear o2 its turned off even though its still there but mine doesn't do this.
