xluben's FogTurbo Bugeye

11 minute(s) of a 297 minute read

Made a peak of 834WHP / 677WTQ at the dyno yesterday. NF built and tuned. IAG closed deck block. PTE 6766 turbo. Ended up turning it down to around 750WHP due to fuel limitations.

Packed up for Proving Grounds.

9.5 @ 150mph

First pass. Street tires. Driven 2hrs to the track with a passenger, full set of slicks in the backseat, and a trunk full of tools and gas cans.

Big thanks to everyone at NF Performance for all the help, motor build, tuning, and everything else along the way.

Thanks to IAG Performance for building a closed deck block with 1/2" headstuds that can handle some abuse.

Here's the full update (with videos) from last week:

There aren't a lot of threads in this section, so I figured that creating a new one for my new setup wouldn't hurt. Since the last time at the dyno/track (666WHP and 9.9-10.1 @ 139-140mph) I have switched to an IAG closed deck 2.5L motorwith IAG 1/2" headstuds. Rotating assembly is similar spec to the last motor. Cams upgraded from GSC S1 (268) to Kelford 282's. The turbo went from a PTE 6266 to a PTE 6766.

Wednesday:

As of Wednesday of last week the motor was still being assembled. NF Performance did the assembly and got it done and back to me Wednesday afternoon. I spent the evening/night installing it into my car and trying to troubleshoot any major issues. Then I did cam break in and changed the oil.

Thursday:

Thursday I drove it about 10 miles to the shop and we continued to troubleshoot. We fixed various boost leaks and then found that fuel pressure wouldn't go above 20psi. We did a lot of troubleshooting before determining it was a torn hose in the fuel tank. That was replaced and fuel pressure was back to normal.

Just to be safe, the car was trailered to the dyno that afternoon. It was strapped down and on the first pull (wastegate pressure of 35psi) it made just shy of 700WHP. A few more 35psi pulls were all 700WHP +/- 10WHP or so. Then we cranked the boost up and made over 800WHP at 50psi+. Fuel couldn't keep up so the final tune was back down around 40psi and made about 750WHP. I threw on the DSS CF driveshaft that night.

Friday:

Friday morning I loaded the car up with tools, clothes, 10 gallons of E85 and my set of Hoosier slicks in the backseat. My brother and I drove 2 hours up to BIR for the Proving Grounds event. First pass was on the street tires (Mickey ThompsonET Street Radials that I drove up on) and no boost off the line, and I did a 9.5 @ 150mph!

Saturday:

Saturday morning we put the slicks on and then loaded a drag map that would make 18psi on the 2 step. Then I watched one of NF's other cars break the output shaft on the first launch (on slicks and boost on the line). I ended up taking my slicks back off and reloading the no boost launch map.

I did 2 more passes. The first one bogged the launch and then hit the rev limiter before the finish line (trying to hold out 4th gear). The second pass caused my velocity stack to fall off on the 1-2 shift and then the coupler got sucked into the turbo (and destroyed it) in the middle of 4th gear.

Precision just happened to have a refurbished 6766 (journal bearing / v-band) for sale on their site for well below retail so I picked that up. It arrived yesterday and I put it on the car for a couple quick test runs. Still seems to be making good power so I am optimistic that the motor is healthy.

The refurb from PTE looks great. Everything looks to have been media blasted and looks nearly like new. A couple cosmetic marks in the compressor cover, but that's it. The damaged turbo will be sent back to PTE for rebuild sometime in the near future and then sold. Let me know if you're interested!
