With a jump like that, I think it will shift the bottle neck to a different part of the system. Id be happy with 15-20% gain.
The intake will limit as it will create back pressure there. The engine is tuned/limited to 18 psi on pump gas, so it should hit that before a 30% absolute gain in flow/power.

The turbo should spool like a son of bitch. I wanted a few hundred rpm sooner, 500 max, but with that exhaust port, it may spool quicker than that.

 

Watching...feel free to pm me more details...cost...what's included.

Thanks, Brian

 

Brian we dont have our PMs turned on so we can provide consistent communication through email and so we dont miss anything.

All of the details are at our velocity heads page.

We would love to help out, please email us with the details of your engine and what your goals are. We will work with you to maximize your set up.

 

Completely agree. 2-3 weeks turn around time typical. Most of the work is done via CNC machines. Simple hand finishing to smooth out a few things. This head was turned out in 3 weeks.

Patrick;

Thank you for the conversation today. I appreciate your time spent with me to explain the details. I will be watching to see some near future results.

Thank you again, Brian

Finally got a text and I know the before and after numbers for the Turbo head. I should get rest of data and dyno sheets this week. I will post soon after.

Baseline was on a Mustang Dyno, 398 @ 16.5 psi, Engine is fully build 2L, Sleeved, 61mm turbo

Only change was stock head to URGE designs/Endyn headwork, before after flow charts here
Headwork netted 13% increase IN flow, 30% increase EX flow using stock size intake and exhaust valves so a tremendous increase in air velocity

Any guess on power gains???

 

+58?

Really curious to see gains on the whole powerband and spool.
