Yeah it's a real struggle lol. I attend college as well so a good portion of my "off time" goes to doing homework and trying to spend time with the kids and wife. Its a balancing act for sure but I'm happy. I was in the military and spent most of my time out to sea so i can definetley appreciate being home and being in a position to at least go in my garage and stare at my car lol.

Thanks for your service!

Going to be tackling my crossover and downpipe next and was wondering where would be ideal wastegate placement on a log manifold setup?

You always want gate priority inline with flow, usually placed on a 90* bend. Would need a visual of some sort to see what you currently have.

Haven't started on it yet so all I have is the log manifold itself and regular truck manifold on the drivers side. Was just curious as I dont see many log setups

On these setups a lot of people put them in the crossover and get away with it. Personally I was with Forcefed on location and I put mine here:



I later ran a screamer pipe straight down towards the ground to vent the wastegate outside the engine compartment. I couldn't

I was able to run all the way down to 5 PSIG without any boost creep in this configuration. Not sure if it's an option for you with the KB log but thought i'd throw it out there.

and this is what I did to clear the truck mani on the driver side:

Thanks for those pics!! They helped tons.. I'm not sure if I can get away with that on the kb log though. Will have to check it out for sure. You're drivers manifold looks good so I'll try and duplicate that. Thanks again

No problem man, That is just a 2.5" schedule 40 mild steel 45. I had purchased it for my log but when I ran into this issue it worked out perfectly to just cut the log off above where it hit and weld this on. Then welded a 2.5" vband right to that.

Let me know if there is anything else you want help on. I have lots of pictures and parts lists.

drecpt83

Appreciate it!! What's up with the cutlass?? You seemed to have it dialed in really well from reading your last post.

jtotheizzo

Sold it. It was running really well. I am still waiting to hear how it does at the track to see how much if any tightening the converter helped. The guy who bought it is supposed to be running it this coming weekend.

When I got it done we weren't having much dry weather so it was hard to tell if it had improved. I certainly could not hold it on the 2 step as high as I used to be able to. What little I got to drive it, it would spin the tires at pretty much any speed when it came into full boost (low boost setting: 15 psi) Was a total blast to drive but I was offered pretty much all of my money back on the project so I decided to sell as I have a couple other cars as well.

Anymore updates? Not many people running the 77/83. Would like to see what kind of power it makes.

...what he said

Only dyno result I've seen from this turbo. Pulled from sloppy mechanics facebook

"This year I put together a 6.0. The engine started life as a iron headed plow truck engine. Took it down to the bare block, put a gen 4 rotating assembly in it with 675,000 miles (yes 675k miles). New rings and bearings. Btr stage 2 turbo cam with new springs. A set of 317's. And a truck intake.
Trans is a built 4l80 from fti with a 9.5" triple disc converter and d3 trans brake.
Rear is an 8.8 out of an explorer, 3.27 gear, moser c-clip axles.
Turbo setup is a 77/83 from vsracing, which fit right where my pt88 fit. 2.25" log manifolds. 3.5" down pipe. 3.5" aluminum exhaust dumped before the axle.
So down to the results. Best number I saw today was 773hp@6,000 rpm. Best torque number was 793@4600rpm. Converter locked.
So the torque number is probably so high because boost was spiking at 230 kpa then falling to 200 kpa. This turbo also wouldn't make more boost at this level either, which I'll double checking everything when I get it back on the rack to be sure something isn't messed up.
I'm also out of fuel. My fuel system is a single aeromotive 340, stock lines, 80lb injectors, and I'm spraying a bunch of straight meth. 2 big nozzles. Fuel pressure drops at this level in the high 11's for afr. So a boost a pump will be going on this week.
Keep an eye out for more results, so far everything is working out like I thought it would!
Almost forgot. Pump 93 and 21 degrees of timing"

Any results with your turbo? Looking at this one for my iroc

drecpt83

Unfortunately no.Project got put on hold for a while. I'll be jumping back on it here shortly

drecpt83

Been a while since I've updated with you guys. Been messing with the car here and there but I've had other priorities to tend to so the car has been on the back burner a bit. But here's where in at so far

drecpt83

Decided to do my own harness.

Traded a buddy a few random parts he needed in exchange for this boost controller

drecpt83

Put some credits on my buddies hp tuner account so I could take vats off and get started. The car fired up twice, then I started getting a controller unlocked timed out error. Talked to tech support and at the end of the day, they said I needed to get another pcm, and I would also have to purchase more credits to license the new pcm. I said screw that and purchased microsquirt. Made more sense financially to me
