Turbo builds

[Nicholas1996]

Hopefully I can get the car broken in and on a dyno with a rpm readout soon. It was down most of this week waiting for a new starter. I'm curious to see where it actually spools up. I wonder if a local fabrication shop could cut and weld an exhaust housing for you if you bring in your current one.

Maybe. My buddy has a shop and he’s willing to take a crack at it, but he’s never done one.

That's fast. Are you running the stock exhaust? It sounds really quiet.

Put the second pump in and base pressure went sky high (as expected) so I tried adjusting it down but regulator won’t go down far enough. Working on a solution to stage the pumps. I have a fore fc2 (should have bought the fc3 but didn’t anticipate to get this far lol). So this is for infinity based only people. Maybe somebody clever enough will come up for something on the stock dme. Anywho:
I plan on using hs0 on the infinity to trigger a relay. The relay will have power from one of the outputs for the pumps on the fc2 . Set the infinity to kick the relay on at say 18-20 psi. Figured I’d share how it’s going. Might put some more boost to it if I see the duty cycle drop on the injectors (doubtful).

From the Corvette forum, "a 10% increase in pressure results in a 5% increase in fuel flow at a given pulse width." Another member says it's a non linear increase. If that's true I would expect your duty cycle to drop a little with tuning.

If that’s the case I’ll push the turbo a little more. Would like to see where the 6266 stops with my 1.0AR

I took the car out to the 1/8 mile drag strip last night. The 1-2 shift is killing my time but hopefully a new transmission brace will make it faster. The track runs a little slow but my best trap was an even 104 mph. For comparison, a 2020 gt500 was trapping 96. I changed out the wastegate springs after racing, I hope they'll let me run more pressure. The car was only averaging 18 psi when I looked at the gauge.

1.8 60ft??? That’s pretty good. What kinda tires?

Made a for sale ad for my car. If anyone is interested take a peak.
thanks.

They're 275 M/T et street r. I fixed my boost problems and running an honest 22 psi now. But now there's no grip in 2nd with the radials on the street. I dont know what tires to go to next.

I had a few good runs with a 50th anniversary camaro ss running a built motor, e85 and a supercharger. He got pulled by several car lengths each time.

Anyway to set up boost by gear?

There is a way with the eboost2, I think you install a button and wire it to the controller. Unfortunately it's not as fancy as the infinity. Now that it's running 22psi, I'd bet I can break my 104 mph trap speed. It's tough though because that's the shift point for 3 to 4 right before the finish line. I'm torn between drag racing Friday night or waiting until Sunday for the roll racing. There's always a lot of high power street cars at the roll races they run a couple times a year.

If you can get some vids!
