I had this done a couple months ago but I figured I'd throw it up here anyway.

We had a lot of issues on the dyno... the car wasn't idling correctly and I was down 3lbs of boost. AFRs were terribly rich. While pulling it off of the dyno, we find out that the line for the water injection wasn't hooked to the engine... there was a puddle of water under the car. This explains the erratic idle, the boost leak, and my IATs hitting 150+ every pull. I was relieved but frustrated. Regardless, here's what I put down.



This is officially:

13psi
9.9:1 AFR average
150°F IATs at the end of the run

These two pulls were back to back, I wanted to see the power loss due to heat soak.

I'm fixing my fueling, and leaning out the tune... I'll do more testing in the future. The boost and IATs have already been fixed (obviously).

Good numbers all things considered.

Makes me wonder what I can hit on a Dynojet.

what mods? nice numbers

Elhonaz

Would love to have that kind of numbers!

Them's some big numbers!

I'd be careful leaning out the tune until you know what your AFR's are with some lower IAT's though.

^^^What he said

I'm not worried about it. Lol.

This was just on the dyno, on the street with the water hooked up correctly I see the normal 16psi, 130 IATs, and low 10s on AFR. I'm tuning based on those logs, not the dyno logs

thats scary tq must break necks

Badass! Now the question everyone wants to know the answer to... How many times/second does your traction control light blink from a 40 roll? Because that will tell you how fast the car really is. Oh and you don't want none

I can brake mine loose at 70+ right now, but my rears are wearing down.. Nitto NT 05'S.. Good numbers for how high your IAT's were.. Lean her out to around 11.3-11.5 and then see where she comes in at.. We have similar mods, I run a little less boost but stay pretty cool and I put down 566 WHP on a mustang... Good luck dialing her in...

that tune looks familiar

They're in my signature but the jist is

MBH longtubes
180mm crank pulley
84mm supercharger pulley
82mm throttle body
Water injection (coolingmist kit)
E85 fuel
10.5:1 compression

I normally see 15-15.5psi on that pulley combo

I'm coming for you, better get that big money motor together before I break your records

I'd prefer more like 12:1 AFR with the E85 but we'll see where we end up.

Yea, setup is pretty similar to your old one. Do you have a graph of the Weistec on around 13psi? Of course your AFRs will be much better dialed in but at least we'll have an apples to apples
