My procharger setup

[S550_LGND]

Im gonna guess - 17-18
D1X here on the 4.5 pulley - seeing 14-15psi at 7500 - low 800's to wheels.

Those are Some Good Numbers!

Sweet I Just Ordered The Same Pulley. Hoping To See The Same Results! I’m Also PBD Tuned

3.90 made 1058
4.38 made 897

I cant believe you guys are running that much boost 17 - 20psi and not lifting heads or gaskets. Im assuming studded heads and built motors?

+1. Also curious if sleeved or not. At what boost level are stock sleeves in danger?

I have rods/pistons, ARP studs, and Cometic head gaskets. Stock block non-sleeved.

I was running a 4.38 pulley at 16-17 lbs before I upgraded the engine.

Get the p1x over the p1 or d1

Can everyone give examples of timing you guys are commanding on 93 vs E85 and boost. Trying to dial in my P1X 93/Boostane around 99 octane. Thanks!

Been so long since I ran 93 kinda forget. But Im thinking Max total was 17-18 range. On E Max is 22-23

Yeah that’s what I’ve seen as well but trying to figure what boost level that applies to?

 

[Roush05]

i'm at probably 12-13 lbs with 93/boostane to 101/102 octane and i want to say i'm at 19 degrees

I have a D1x and put down 1058 to the wheels.

Yesssssssssssss

As long as they don't detonate, they live.

I normally set everything limited to 23 (can't go over that)
However, if you wanna poop your pants, I have a car that runs 27...
(oddly enough, its still together lol) How in the world I don't know. LOL.

What lambda is being commanded with you boosted E85 guys. Currently I’m at .77 on 93/Boostane thanks

Would that be capping MBT at 23?

Well I'm no tuner but pretty sure Lambda should always trying to be 1.0. Mines flutters .97 -1.02 but is trying to maintain that 1.0. Should be that way for any fuel you run. The AFR will change with different fuel types.
.77 seems really rich.

 

[Roush05]

.77 at wot is fine from what I've seen. 1.0 at wot means you have a dead engine lol.. lambda is a ratio, for gas 1.00 is equal to atmospheric pressure I think In psi (14.7). A .77 lambda is equal to 14.7*.77 which is an AFR of 11.3.

It has to do with stoichiometry which I used to know about but have forgotten since I've been out of school.
