Anyway it's all back together and running awesome. Power and torque is instantaneous. I'm now having fun watching the PSI, torque and horsepower ratings on the SRT engine performance page.
Did my first 0-60 run in my usual spot where my times are traditionally 4.3 to 4.6 seconds. Pulled a 3.9 the first time and 3.7 the second time. Haven't tried a quarter mile run.
Irregardless of 0-60 or quarter mile times, where this beauty shines is when you need to pass someone or just cruising. It will put you back into your seat at almost any speed. I don't race or track the Jeep but have accomplished what I wanted to just in case I need to get ahead of someone in an instant.
The only thing that still needs to be worked out is the transmission shifts. Doing a wide open run, the shifts feel a little sluggish. I think it's even hitting the rev limiter from 2nd to 3rd shift. I wonder with this transmission will it take it a while to relearn the shift points. If anyone has knowledge in this area, please advise.
I also have to say The guys at RIPP both Chris and Ross have been awesome through the entire process. They new about my issues and were quick to assess and help resolve many questions I have.
All in all, awesome kit so far and would highly recommend to those looking for a safe and more affordable option.

No need - the canned tune at the moment is softer for again, conservative reasons - we got it covered in our tune update, which we will be updating in our canned tune next week.

Our main objective, contrary to our competitors, is to keep these vehicles on the road with our systems. - We've seen the debates regarding compressor size and it literally makes us laugh.
As you pointed out, these are 10.9:1 compression Hypereutectic
pistons ... 5-6psi with an 1150cfm blower is plenty and our conservative tuning should keep things safe, including the trans. Furthermore, running 5psi on a 1400cfm compressor is nearly the same as running 8 on a 1150cfm blower, which can bring things to a break point quickly. We can assure you we've tested from 2-8psi and monitored all aspects of the engine, including
- Exhaust Gas Temp
- Cylinder Head Temp
- Air fuel
- Air Intake Temp
- Oil Temp
- Trans Temp
- 4 knock systems and patterns
- 5 oil analysis in 5000 miles
- Spark plugs read 10 times with pics
We own a 2014 SRT Jeep and want to keep it running - It wouldn't be hard for us to break it if we wanted to and build an engine and hit it with 20psi on a larger compressor. We are and have been a speed shop for 20 years... We can handle installing a set a headers, pinning the heads down with studs, installing a larger fuel pump and relay system, cutting the front end apart for 3" piping, hacking the AC apart, dumping the trans out and beefing up the internals, sending the trans/case out to make sure the output shaft is strong enough to handle the torque load and getting a high stall converter (food for thought).
But that's not what we sell at RIPP, we sell a gentleman's kit, which installs is hours not days and requires hundreds not thousands to own. So to you, we say, you do what you do and we do what we do

Thanks Scott, there is bit of learning we factor into the tune as well, good advice.
