Several people there made comments like that when they saw the graph.

I can't believe this ---- at 180kpa. Too bad they don't have a v-band flange option.

If torque is believable, so is horsepower.

It's an EFR, so he's not creepin' (unless the EBC or boost source is failing)

Treadstone and FullRace are working on it.

I wonder if they will work on a housing that keeps the wastegate.

This is with a smoothed port squaretop intake manifold and head with smoothed intake ports and combustion chambers and polished exhaust ports. I'm using a MBC and Forge wastegate actuator with a 5Lb spring to control boost.

BTW, The car ran flawlessly today at the track and I won my class. I'll post vids soon.

Edit:Andrew, I owe you that 4th gear run vid. I ran out of tape on the camera and have had too much beer after celebrating after I got home

Here is the video of my run in the timed event at Arroyo Seco Raceway.
Definitely not one of my better runs.

Can you get your boost gauge in the same shot? Or just a datalog.

If I cant get the gauge in the shot, I'll grab a datalog, it may be a bit though. Cops are like roaches here. The hotter it gets, the more you see.

Yup, 4.3 diff.
