    Thanks man! Well if you do make it, or are ever in southern utah regardless, let me know. I'm 45 minutes from Sand Hollow up the hill (bike ride from the last WE Rock competition). Can always use more friends to go wheeling 😁 even if I have to take the FJ out to do it
    I've been trying to get up there for a bit now to ride bikes at Brianhead also. Might just have to come up and roll around looking for spare seats if I don't get it done by then. Always need more wheeling friends

I'm shooting to just run 91, maybe have a tune for race gas but I doubt it; course, I put the highest compression stock LS heads made on it which was before I decided to go with the blower, so I may be at a cross roads in the next few weeks of race gas or different heads. I think inevitably I'll go to a top end optimized for the blower and at that point I'll keep it with 91 probably.



      Thanks man! This build is such a cluster, as time goes on the budget seems to keep increasing. Was supposed to be super cheap initially and that's why I went with the lizard chassis, and now it's turned into anything but cheap and it's all crammed into the little chassis lol. Nothing against Thomas and I love the lizard, but a bomber or something would've rid me of a lot of growing pains.
      We have been on E85 for several boosted builds now. works amazing if setup and tuned for it. Whats your current compression ratio now?

        I hadn't thought seriously about E85 due to the inconvenience factor, but a guy I knew also swore by it for boost, especially turbos. He said the whole engine ran considerably cooler on E85 plus could get more power of it, and I thought he was said it was $4-5/gallon in barrel form which isnt bad. I think I'm around 10.6:1, a stock LSA is 9.1:1 though I've read quite a few people with a LSA on a LS3 which is 10.7:1 and they apparently (or lack of saying otherwise) can run pump gas.

          yikes... thats not pump gas territory. I run pump E85 at around $2 a gallon. I'm a hair shy of 1200 HP at 15 lbs of boost. E85 downfall is consumption. I really need to design a larger custom fuel cell.

              Now that the weather is cooling off and Trail Hero motivated me, I've been chipping away at stuff. The accessories are fully mounted and ready to rock. Had to get some socket head cap screws but she's ready to boogie and everything is turning over fine. I'm worried the idler pulleys aren't parallel enough to everything else but we'll see when it fires up.





              All the coolant soft hoses are routed and in place. I also removed the LSA boost bypass actuator and will do something to keep it permanently closed off. From my reading the only down side is the engine will get "more wear" since it will constantly be making boost, where as normally boost is bypassed from the intake at idle and low throttle. The actuator is in the way of my top coolant line, and I really don't give a shit about engine wear since this isn't going for 200k miles, so delete and block everything off.

              In my quest to get it running "soon", I need to plumb the hydro pump somehow so it doesn't burn up. Well may as well just fully mount the steering. Welded up the high steer that I've had laying around for 6 months.



              I will be mounting the ram soon, but the Howe kit just comes with some short clamps that aren't tall enough to clear the gussets inside the hydro skid, so I ordered some steel billet and will machine new bottom sections of the clamps that are the correct height and then tap some bolt holes and weld them straight to the hydro skid. The stock ram clamps, and from the sounds of it most ram clamps, have the bolts in shear so by welding the bottom of the clamps the load path will be directly through the clamp into the skid. Additionally I have new ball joints that showed up, and will be ordering new 35 spline unit bearings and axles and all the other shit in the near future.

              Moving on, I finished some welds on the front of the chassis and added the outer plates to the motor mounts and welded them in. Everything is first pass still, but I think it'll be good enough for mild partying before I tear the chassis down for final welding/sand blast/painting in the far future.



              I started plumbing the fuel system today. I had bought a bunch of hose, and then realized that the reusable AN fittings I have need SPECIAL hose that of course costs a metric ass load. But I already have Fragolas fittings on literally everything, so I had to buy their special hose ($750 for 40ft of -10 and 20ft of -6). Lesson learned that the cool fittings lock you into using the special hose, not that it isn't nice, and I've already had a few spots where disassembling the fitting and trimming the hose back was nice, but in the future I think I'll go with crimped lines or premade stuff. Anyways, now that I have the special line for the special fittings, time to plumb stuff. A week or two ago I made brackets for the fuel filters, fuel pump, Y splitter, and regulator.













              I've been looking for a nice way to route the hoses, right now it looks like I'll be machining some brackets I can weld straight to the chassis and have a little retainer plate and bolt to hold everything neatly in place.



              I have a few more lines to run, and after that will plumb/install the steering and then she'll be ready to fire up. I have some ebay headers I'll use to fire the engine up, but they won't fit once I get the firewall in place but good enough to test everything.
