Evo X upgrades

Torqued that oil feed banjo bolt and it tightened 1/4 turn. It'd be nice if that were the issue.

I changed the oil and left the under-tray off for Friday's visit with Shane. I can't tell if the Hobbs switch is kicking the pump into high gear or not. The car gets so loud during a pull that I'm not going to hear the pump change speed. I've done a couple half-pulls to 15psi and the AFRs look good @11.2-11.3.

That's good! Hopefully it stays that way. Does the Weldon controller operate a dual voltage setup then?

Not quite, it's an interesting device. It uses some sort of pulse modulation to limit the current but it always operates at the same voltage. You use a pot to adjust the amount of current sent to the pump at idle and then you send voltage to a terminal to trip it into full current. They say it is a 0.5v drop vs alternator voltage at 20amps.

It feels like Xmas Eve to me. I want this car done so bad.

I actually have as many spectator events planned for this season as driving. ChumpCar fascinates me. I'd love to join a team next year.

The Weldon worked perfectly from the first pull. The fuel tested as E81.

I was a bit surprised by the number for my 30psi tune. We dialed in my normal 25psi tune at 440whp.



I'll scan the sheets after work.

Impressive peak numbers and even more impressive powerband. WOW! Congrats dude!

Dam those are some very nice number for a motor with low compression. Your car has an awesome power band. Hope I can get a ride in it sometime.

Mark Leasure was there to get his IX tuned after me. He was saying that he prefers lower compression and turning up the boost. I'll just drive it if the compression numbers remain where they are (115-ish).

Drive it until it smokes enough to bother you, then rebuild. No need until then. Mark is right, it's what I suggest, and I know Shane has said similar in the past as well.

^x2.

Congrats on teh numbers, now go have fun with it.

Dyno-Queen Tune




Road Course/Normal Tune

Nice numbers! 470 is some nice powa!

[Murlo26]

Congrats bud! Glad to see this turbo fully unleashed. I spoke with Shane, sounded like you are still blowing some smoke? Is that from the turbo seals still do you think?

Regardless, great stuff. I must have literally just missed you. I got there when Mark did his baseline tune and shot the shit with him while his car was tuned. Was hoping to see yours in action.

Nope, the motor has 115 compression. Most Evos are like 155.

Well it doesn't seem to affect power haha

It only blows smoke after a pull. I imagine it might burn a quart during a track day but compared to the fuel burned, the oil seems like nbd.

Very nice Michael!!! Damn this a long thread where's the mod list?
