Is 28 psi safe for stock block, head bolts, and rod bolts? Just curious because I'm getting mine transferred to the E in about two weeks and was wondering what the normal or safe boost level should be.

 

Max IDCs are 70%.

 

I'm on stock block, head bolts, and rod bolts. I think I'm good. My tuner says I'm good. My wife says I'm terrific.

 

right on. thanks for the info.

 

WHen and if you ever go back to 91 octane, the IDC's might be around 50%ish

 

Jim, you might want to turn down the boost a bit on your car :P

Australian Company to Issue Arizona Speeding Tickets
Arizona to use 200 fixed and mobile speed camera units to raise $165 million in revenue.

Speed cameraThe Arizona Department of Public Safety announced yesterday that it would pay an Australian company $28.75 for every ticket it is able to issue on state highways. By September 26, Melbourne-based ticket vendor Redflex will activate what will soon become the largest speed camera operation in the United States. Governor Janet Napolitano (D) commissioned the program to generate $165 million in revenue from the $165 citations. Redflex hopes this bottom line inspires other states to follow.

"We fully expect this program to provide a benchmark for the role speed enforcement will play in traffic safety in North America in the next decade," Redflex Traffic Systems CEO Karen Finley said in a statement to Australian investors.

Redflex already operates two speed vans on behalf of state government, but the new contract expands the program to allow up to 200 automated ticketing machines. The company plans to blanket the state with 40 mobile speed vans, 10 mobile red light camera systems, 90 fixed speed cameras and 30 cameras capable of simultaneously issuing tickets in two directions.

To help minimize voter backlash against the program, lawmakers last month eliminated points for these photo tickets, ensuring drivers would avoid insurance penalties and license suspensions. Early deployment plans also show out-of-state motorists will be a prime target. According to a state police news release, the placement of cameras on Interstate 10 west of Phoenix will issue tickets to "commercial and non-commercial vehicle traffic from California." Each highway patrol district will have at least two mobile speed vans to place in high-volume locations. State police have already dropped the speed that triggers a citation from 11 MPH to 10 MPH over the limit.

 

Same here - stock motor/head other than cams, stock head/rod bolts, stock fuel rail, stock FPR along with Walbro and 880s.

 

 

I think a lot or perhaps most or maybe even all of the perceived weaknesses in the EVO are highly overrated.

 

When I tuned Brian Allens car on 91 with the RC 1000cc his where:

7531 rpm
65.26% IDC
38lb/min
1895 AirFlow
216 Load
10.9 AFR

I can't remember the boost off the top of my head but probably around 20-21psi at 7500

317whp peak on our Mustang, which made 339whp on RRE's dynaPak

 

Higher IDCs there Bryan due to your 91 and dumping fuel at it (10.9 AFR).

 

Yes, skiracer was talking about 91 octane IDC, check the quote.

The boost level being held accounts for the higher IDC as well, MBC would have lower IDC.

 

Don't think everyone tunes to that AFR and boost level, though. Lower boost and leaner AFRs would be less IDC, yah?

 

Yes. Just one example.

Sorry I shared any data.

 

Bryan, does your Mustang always read low?

I made exactly 318whp on the local Mustang and 318whp on the RRE Dynapack. I was actually expecting a bit more at sea level. Both on 91 at 21 psi tapering off to 18 psi. With no boost taper I would think you should be seeing more than 317whp.
