Here's a quick dyno update on my Sr20de Autech after installing Jeff's custom header. Rob Fuller at Zcargarage did the tune and the improvment in drivability is amazing. I took the car to lggpr in Kansas and autocrossed it and put it on the track. It was sooo much fun.
It now produces 171hp and 150 ftlbs of torque. Certainly an improvement over the last dyno of 161hp and 140ftlbs.
The engine is now with Rebello Racing to work their magic. Hopefully I'll have it back on the road by Spring. On my way to Solvang, it will go back to Rob for another tune which will include E85 this time.

Shannon,
I'm glad you made the trip all the way from NM to San Jose! Wish I could have been there for the dyno session. Looking forward to your return and more power!
For reference, here is another Autech SR20 (in a Miata) that Rob dyno'd, it was not a full tuning session but it made 179hp/149tq at the wheels:

The Autech is a variable cam timing head, right?
Greg,
No, the Autech SR20 has Variable Timing Control (VTC), valve lift and duration are NOT altered.
The SR20VE is the model that has variable valve timing, switching between two different sets of cam lobes..like Honda's VTEC or your Celica's engine.
The SR20VE makes 200+whp easily. This is what Mike (RCMike) runs in his roadster.
