Looks like more of a supercharger plot than turbo plot. Really weird

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

No you won't. :giggle:

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

God damn.

Ok tq is believable but what about hp.

If torque is believable, so is horsepower.

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

Braineack 04-28-2012 12:48 PM

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 :bigtu:

Here are some pics and video from the dyno session.

Edit: Runs are at start and at 2:50.

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

Here is the 4th gear run video...
Ignore the dead temp gauge.

soviet 05-03-2012 11:36 PM

looks about right!! are you on a 4.3 rear end?

mrluckys 05-03-2012 11:59 PM

I can confirm that this mofo is balls fast. Butt-dyno confirmed.

Savington 05-04-2012 12:06 AM

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

99mx5 05-04-2012 01:27 AM

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.

Faeflora 05-04-2012 03:40 AM

wow. i hate you
