Damn, I was going to go but ended up working on the car, haven't been to the track this year yet. How is your new setup running? We have our Iowa Auto Forums street car race on the 6th. I doubt I will make the manual class race, but plan to be there for sure. Watching big power manual cars can be a trip
Your car would be a good one for the auto class if it meets most of the requirements.

Really sweet build man. I like it! I try motivating people to use these style manifolds and making a "kit" but people look at me like I am crazy. Thanks for sharing. One of the guys here at work built his 13 V6 mustang turbo kit, and based off space, had to place the MVS38 in the turbine housing as well. It does indeed sit right on top of the turbo and seems to work just fine in that configuration.

Put a few more mile on this thing, but needed to tweak the inlet pipes and boost pipes for more clearance. The leaf spring smacked the drivers pipe and bent the rear bracket so I ended up cutting it in a few spots and making more room. Such a pain, but it is much better like the passengers side now. I also had to dent in the inlets by the tires a little for more turning clearance like the TTIX kits do. If I had run the pipes in a higher arch it would clear the tire more, but also make it more of a pain to get to the filter. It should work fine though.

Good to get this pile on the road. Went from 630 hp with my rough pump tuneup and had My buddy Clint from Crown Tuned get it sorted better. We didn't do anything on the dyno except install my temporary manual boost controller and drain the remaining pum gas.
Car feels nuts on the road with great midrange torque. We turned it down to 15psi form now and filled the tank with corn. I'm really surprised it did this well. I didn't really think I'd be maxing out my newer clutch so fast but I guess that's a good problem to have.
Not much left to make at this point. Turbos were getting close to maxing out and I'm not pulling the new clutch until I need to. This is my stock ls6 block so most things are maxed out together.

Did you do all the fab work your self? Looks pretty dam nice.. Maybe I'll get to see the car at the track this year but I think I'll hid my car so you guys dont laugh at my crappy work

Thanks, the only help I had is with the fine tuning and tig welding the stainless piping. I did the manifolds myself. I use my mig to tack the 304 exhaust parts then have a friend finish. A Tig welder is next on my list though.
I build everything myself, fuel system, turbo, intercooler, head porting, cam, valvetrain, drivetrain, etc. Sometimes it takes forever, but it turns out better in the end.

Yes I know it's std but boy was it hot and muggy in the room.

Totally uncorrected probably would have broke 1000 if we could keep it down and the clutch would hold.

This graph just shows the curve better due to no tire spin. Pump gas max vs some corn.

Final mph sheet to get an idea. The wheel/clutch slip sort of ruin the rpm trace but mph shows up better. Ignore the big spikes as that's from slip.

So Savage. And I love love love the DIY work!!! Makes it 100% more satisfying when its finished, and about 90% less expensive!!
Great work!
Great work!

Thanks for the nice words guys, it's nice to show off the finished product a little. Compression is a little high for 92 pump no meth(~10.2:1 give or take .1) so not huge numbers to be had. First pull on my tuning it made 630ish st 9 psi, we quit at 13 psi on pump and 741 I think. It was either add timing or take out timing and run more boost etc. We didn't see much to be had and not quite as safe pushing it so we quit there. The 9" Treadstone worked out decent and I'll have to look at the logs, but IAT temps never got over 130 at lower boost I think, but pulls don't last long at this level on a dynojet. On the street they will get higher depending on weather.
Everything was working great on E85 though. With a clutch and good weather I would have went to my 2.5 bar SD limit so 22psi or so with things working well, but next time I guess. I told myself I would stop at 15psi this time, but you know how things go. The damn thing made like 850 at that point and it was hard to resist trying more. I'll try to back up this number at the track if I can keep it in one piece. The number was really 972 uncorrected so in a humid 82 degree room that's decent. We all know how our turbos cars run in cool air, not to mention I drove the car 2 hrs down and back in one piece.
Next time the drivetrain is out it will get a stronger clutch and drive shaft/coupler/stub shaft upgrade. I would have done all this up front, but things were in good shape so I ran with it since those parts are around $3k. I'm not so sure about the ls6 block at this point either, with much knock at that level and things might not be so happy.
