26GT got boost - not ESS/Whipple/Procharger *Roush 2650 Phase2 810hp*

My custom tune. Shes a ripper. No regrets now that I can tune them. What a killer setup this is now for an otherwise stock car.

What's the 60 to 130 now?

What's the 60 to 130 now?

I havent draggy ran it yet, but I had another video that I tried to time it with after the fact and I think it was right at 6. Its got to be close give or take a few tenths. It pulls like a freight train on the top end now. The 2650 is like the perfect blend between a centri and a twin screw. Not as much tq off the hit in the low end, but pulls a lot harder up top. Still seeing 14psi even in the muggy heat. I have to do more tweaking. It seems to want more spark like you were talking with your ESS kit. But its been too hot and wet out here lately as Im sure you noticed... I got some 555R2's coming tomorrow I want to test with this weekend for a 2nd gear hit.

Very nice, what RPM is that capped at? It looks like its getting almost to 8k? Sounds mean too!

7800 for now. I’ll test with a bit higher and lower as well as changes per gear change to see what’s fastest.

14psi

Wow. That is a lot.

 

[ZXMustang]

Wow. That is a lot.

That’s the pulley that comes with the kit lol. I was going to pulley down too at some point.

LOL, I was kind of hoping the vacuum gauge was going to start reading positive after 0.

You can Forescan vacum/boost into the gauges. That is what I did. The vacuum stops at 0, as you can see.

Yeah you can. It’s not super accurate but it’s better than nothing. I can see the map data in the logs and can do the math to work out boost over atmosphere.

There is a PID for boost pressure in the scanner you don't need to do the math.

It’s a math. There is no measured boost so the pid is two other PIDs in a math.

The scanner will do it for you with the boost pressure PID. The car has a map sensor so the boost pressure is accurate. No need to do any math. It actually uses a MAPT sensor so it measures temp as well which would be used as IAT2.
