Gen 3 coyote with Hellion TT 62s on 18lbs, how much WHP

[erikkire18]

I don't know how your eboost controller works, but on my Boostleash, you don't set it to say 12 psi and expect 12 lbs of boost. If I set it to 12 psi, its adding 12 psi to the top of the wastegates holding them closed longer. So for instance, on wastegate pressure without the boost controller, I see 8lbs of boost. If I add 5 psi using the boost controller, I end up seeing 12 lbs of boost. If I add 10 psi using the boost controller I see 16 lbs of boost. Its not a 1 for 1 correlation. You have to figure out how much to add to the top of the wastegate to get your desired boost reading.

oh I see what you mean, yah It was set up previously by the shop where I dynoed it at. I gotta see how to reset the duty cycle and adjust the controller. I got a GFB II controller

It seemed to like all the boost until about 5500 rpm, lol.
Almost 1000 ft/lbs, goes to show what a stock Coyote can take for a pull or two anyhow
I bet the trans was like WTF is going on here?

its a built gen 3 short block from RPG, pull was made in 4th gear. but yah made all the power up to 5500 haha

What type of headers do you have?

I purchased the hellion kit awhile ago. Just having it installed now. Also looking at a RPG engine myself.

I used my oem manifolds. Yah RPG is great customer service and know what they are doing. I got a gen 3 with the 12:1 CR

I ended up getting the 4 to 1 headers. I see you're not too far from RPG. Have you been to their facility?

Yah the 4 to 1 is good also, I’d get those but used my stock ones for now. I haven’t been there, not sure if it’s open to the public, overall good customer service and communication. Yah I’m like a 5 hour drive from Clovis.
