The Quest for 275 MPH

FST SNAKE · Jan 20, 2022

These pics show some of the components located in final positions. There is a lot of work that has gone into making this all line up correctly. Everyone involved has really done their best and I could not be happier with the results. At this point the piping will be the next major project to complete. I have a lot of mandrel bent pipes we have to cut, tig welded and mounted/supported from front to back. Once all that work is completed the piping, floor, hot side of turbos etc will be sent for heat treating at Jet Hot Coatings. Other parts will be painted and then the whole thing reassembled. I'm so ready to hear this V10 run again. There's 100s of small tasks to complete but at some point in 2022 I will line it up for an attempt at 275+ MPH. Looking forward to that!!!

Here is view with the bumper installed, it shows those turbos looking very stealthy or somewhat anyway. Nice fit for all the parts so far, we are running hot pipes next week and hope to wrap that up by weeks end. After that we start the cold side and it should be about a week or so also. Then everything gets shipped to coating.

Very cool! I always liked the idea of rear mount turbos on cars in place of mufflers. I'm sure there are some disadvantages depending on what exactly you might want, but I think everything is going to be a pros/cons thing.

FST SNAKE · Jan 24, 2022

Boost lag is probably the biggest concern for most but in reality, for me it's a benefit. I leave the line easy and really don't need the boost to launch, once it's rolling, I can go WOT and very quickly go thru the gears. The engine management system is set up for boost by gear, so each shift brings on a little more boost and helps to minimize wheel spin. Moving everything to the rear helps in other ways also, more room for bigger turbos, bigger intercoolers, puts a little weight over rear wheels which the back starts to get light and wiggle above 240 or so. Overall, for the speed I'm chasing this isn't a bad way to go. I will keep you guys advised of the progress and the also what the numbers look like once we are on the dyno and tuning it. Thanks, David

Hot side pipe fitting and tig welding over this week. It's coming together and we will be on the cold side probably mid next week. Here are a few pics showing the work we have done so far.

Here are pics after we made adjustments for fit and then tig welded the pipes. It's getting there and we haven't had any major challenges that we couldn't overcome.

Wow, those are some pretty fabrication skills. Impressive when you can make a multi-section pipe look like it was just bent and not welded.

FST SNAKE · Jan 28, 2022

Thanks, I can't take credit as it's a team effort on this build. I tried to get mandrel bent pipes, but they can't bend the radius I need in the shorter distances or the changes in offsets that are needed. I'm sure there are facilities out there who have better equipment that could do that. Maybe at some future point I could have them reworked into single pieces.

FST SNAKE · Jan 28, 2022

The intercooler pumps arrived today, finally at a point where the parts are arriving faster than we can install them. These are rated 40 GPM each as well as the intercoolers are rated 40 GPM each. Hopefully the combination of 2 ice boxes, 2 chillers, 2 pumps and 2 intercoolers will keep those IATs lower and allow for big HP and speed toward the end of the run.

Still making progress with hot and cold side pipes, here are a few views of where we are at now. Wastegates arrived and will be installed next week. If all goes as planned I will be starting it in 4 to 5 weeks. I will share a video when that happens.

At this point we have made some progress toward finishing up hot and cold side piping. A lot of time is spent tack welding and checking fit/finish and then reworking it until it's as good as it's going to get. Wastegates have been located but only tacked in place so they will be tig welded next week. Cold side up top is coming along and by mid-week it should be to a point that there is very little left to do on it. I can see the light at the end of the tunnel for getting it to a point that we can start the engine to check that all systems are working properly. Then unfortunately we have to dismantle it and send all the parts out for coating and paint. While that's being done, we will rework some of the engine components so that when it's all back together we can see what it's capable of.

The rear mounted setup you have is beautiful, and makes massive sense. Rear setups are not preferable for guys doing the 1/4 mile due to the long tube travel for air being pushed to the engine and air compressibility adding even more lag. For a top speed run, this is not even an issue anymore, as your mass flow will already be established once you start getting into the gears and the lag effects will not be a factor. Bonus to relocating hot turbos and reducing the heat shielding they need while keeping the exhaust exit at the back of the car. I hope you have a sweet intake scoop design somewhere near the airflow and not stuck in a low pressure cavity. Keep up the fantastic work! Really excited to see it all come together!

Thanks Jordan, and I will have " sweet intake scoop design ". It will definitely be in the airflow and hopefully made from CF if I don't run out of time here, otherwise it's going to be aluminum at least for the short term.

We have completed the hot side piping and disassembled it to be sent off for coating. Attached picture is the passenger side including turbo housing. Lots of other work to be done and we are currently working on cold side along with hoses for oil, water etc. It's taking more time than I expected but it's getting there. A lot of vendors have longer lead times so that's affecting the speed of the build.

FST SNAKE · Apr 13, 2022

This is the mount, hoses and scavenge pump for the turbos. I'm trying to run the smaller lines thru the frame rails and keep the transmission tunnel open for the larger lines such as dry sump hoses and fuel/return lines. The back of the car is starting to get a little crowded but still there's a lot more room with rear turbos vs front mounts.

FST SNAKE · Apr 13, 2022

Here are some pictures of the cold side pipes connected to throttle body. I mounted the Moton reservoirs to the side of the pipes to get them up top for easier adjustments. I used roll bar clamps to attach the reservoirs to the pipe brackets. I had to remove belly pan before to get to them. Also installed a nitrous plate to help with the IATs toward the end of the run. This would be a small shot, maybe 50 to 75 at the most, I don't need the HP so no need to go any bigger. This section of piping will be painted GTS Blue to match the car.

FST SNAKE · Apr 14, 2022

New rockers, steel/roller bearing 8000 RPM designed by Prefix and built by Jesel. These are definitely an impressive looking product. We are going to pull the heads again and inspect the lifters to make sure they are up to the task along with replacing all the pushrods with even stronger ones.

Here is picture of the intercooler pumps, they are Meziere pumps and will pump 40 GPM at max flow. We will regulate them to what we need. I will locate the ice boxes behind the wheel well and hope to get about 7 to 8 gals per side. That will give me enough ice cold water to make the time required for the run.

Wow, what an awesome build @FST SNAKE! When do you feel this will be ready to race? How much more do you have to do to it and where will you be running it to try and hit the 275 mph mark?

I think we have at least 3 months left in this build so maybe finished in July. If I get it done early July I will take it to Loring Maine to make the attempt, if it's after that then maybe Sept in Maine. If an opportunity to make a few passes on the space shuttle runway comes up I would prefer that as the driving distance is so much closer to me. I can be there in about 1.5 hours vs the 24 hours to Maine. The further we get into the build the more confidence I have in making that 275 number, it's even possible it might surprise me on what it is capable of.

FST SNAKE · Apr 25, 2022

Got my complete hot side piping, turbos etc back today. I plan to wrap or sleeve them on top of the coating. I hear that isn't the right solution and can degrade the pipes over time, but reality is I need them to work for less than 30 seconds from zero to 275 and after that I'm not too concerned about them. I figure it's more important to keep the heat in the turbos then to concern myself with my exhaust pipes 2 years from now.

I think if they are coated that the wrap shouldn't be as bad. Typically speaking I thought the bigger concern with wrap was that it trapped moisture, so it was pretty much a recipe for corrosion when you've got hot metal next to water. I would think the coating would offer the corrosion protection, not to mention I have a feeling your car probably won't see a lot of wet conditions, though it could be your daily driver for all I know.

Maybe not quite a daily driver but you are right in that I don't drive it on rainy days. I do want to say it has AC, radio, ( all working ) insurance and a tag so I do get to cruise around the area with it. I suspect the change in temps from start to end of a pass probably creates some condensation, but my pipes are 304-L stainless steel so I'm not too concerned.

New ACR-X rotors installed up front, lets me run a slightly larger brake pad, I will take all the stopping power I can get. Hot side starting to go back together, I'm waiting on Design Engineering sleeves and turbo blankets which should be here in coming week. There is a very dim light at the end of that tunnel, I look forward to it getting brighter.

FST SNAKE · May 17, 2022

Got the blankets in for the turbos, really good fit. I'm starting to wrap/sleeve the hot side pipes so I can re-assemble them and then finish up the cold side. Heads are at Greg Good's place right now so I need those back before I can wrap up the cold side, no intake located keeps us from finishing those last few feet of cold side pipes.

Been a while since I've posted any updates. We are in process of a refresh on the engine, new rings, bearings, Greg Good refreshed the heads with beryllium copper exhaust seats and Inconel valves. Also drillled and tapped rear of the heads to help with the cooling issues the last 2 cylinders tend to have. We also will ring the heads and block to allow for some big boost at the fast end of the runway. It's making progress although it's very slow progress.

Any new updates?

FST SNAKE · Jan 10, 2023

I've been busy on Blucifer over the holidays, mostly in the engine. I was concerned about the stock crank being able to handle the WHP level we are going to, so I bought a billet crank from Callies. Then that led to new Callies rods, why not since we are in there anyway. Then of course the rods are connected to pistons so naturally they had to be replaced with new Wiseco custom made ones. It's a vicious cycle lol but I do want to make sure I have the best opportunity to make the 275-285 speed when I make the attempt. The heads have been grooved, and fire rings are installed to match the receiver grooves that were cut into the block/sleeves. This allows for the big boost I have planned.
