Thought I would share some pictures of the new custom built intercoolers by Bell Intercoolers. These are rated 3000 WHP and definitely fill up the hatch space. Shutting the hatch was done very gently the first time but there is enough clearance.........barely. I'm sure you guys noticed that that Blucifer is a little different than most twin turbos with this build. I like different and thinking outside the box is my thing. I'm sure I will hear a lot of comments about boost lag etc but I'm building a landspeed Viper to break the 252 MPH record that I set on Jan 18, 2020. I'm chasing 275 plus MPH now and I have time to get thru the lag. I also have a progressive nitrous system to help with the launch and honestly that V10 doesn't need the boost to launch. There are advantages and disadvantages to front and rear mounted turbos and we are working thru those. When it comes down to it I'm confident that I will have the WHP/torque it takes to break 275. I do need to continue the work on some of the aero to help with that wiggle that shows up as it closed in on 250 but we have some thoughts on that and have started working on that also. I don't have a date yet to make the run but I will keep you guys advised. Appreciate the help and support from everyone on this attempt with special thanks to Jon B, Teamtech, Forgeline, Precision, 6XD Sequential Transmissions, and others.

You mentioned several times you have a new diffuser for the back and we haven't seen photos of it yet. Looking at this photo reminds me that the F-1 aero wizards have used "blown difffuser" designs on the cars at various times in the recent past. The idea is that the exhaust gasses exiting in a specific part of the tray helps to create more air velocity and more downforce. There's a lot of CFD computer modeling that goes into this, but even without - it intuitive work could help you keep that tail in line.

[DEMO MAN]

WOW that pic definitely shows the aero work that went into that car. We scrapped a few of the early designs on the diffuser and and I think I'm on V5 or 6 at this point. With all the delays I have more time to put into the aero. It's not something I want to get wrong so if possible I will check on wind tunnel time up in NC. Adding the weight to the rear will also help as the back gets light as I approach 250. I also will play with the rake of the car, we have data from previous runs from 228 to 253 MPH and I will use that to make minute adjustments. The key is to make tiny adjustments and only one at a time until we see what that does to the car. I will be hanging the turbos back on the car soon now that the intercoolers are located. Once that is mocked up and everything fits I will fab the final design on the stainless steel trunk floor that supports all the components. After that it's the new fuel cell and the 2 ice boxes that are located between rear wheel wells and rear bumper. It's been an interesting build since I decided to put everything out back. Love to hear what you guys think about any of it. David

[GTS Dean]

Another good photo from the same period. Check out the badging on the rear bodywork! Are you going to pack the intercoolers with dry ice like the 1400hp 1.5L turbo F-1 teams used to do for qualifying and the start of the races?

[DEMO MAN]

The exhaust on Blucifer does exit into the diffuser similar to the pictures you posted. The ice boxes actually use a chiller system that brings temps close to freezing. I haven't done any real world testing yet with it but the biggest issue we had on the 252 MPH run was IATs. It cost me a lot of speed as the engine management system kept pulling timing, then fuel and lastly boost as the IATs got too high. I had expected a 265 to 268 MPH run but was still happy to break 250. Hopefully this new system will keep those temps in check, if not the nitrous is programmed to come back in and help to maintain those IATs.

If you don't like the current atmosphere, just bring your own in a bottle.

Very cool project, and always enjoy seeing pics of updates.

LOL exactly, wish I could bring my own tail wind....

The build continues, we had to move the turbos around a bit to accommodate the fit of the piping and intercoolers. All the mounts for keeping everything in place back there are being fabricated and tig welded in place. Real shame to grind and weld on that beautiful cage but it will be repainted when we are done. Once all these parts are in final position, we will mock up the ice boxes which fit between the rear wheel well and rear bumper. There is actually a lot of room there to put one on each side, need to keep that air traveling up front as cool as possible.

On another note, it's possible the attempt at 275+ will happen at another location instead of the shuttle runway. It's obliviously my first choice with the quality of the runway and the organization that runs that event but timing may not work out. I looked for another location that would allow for 1.25 to 1.5 miles which is the distance I calculate I need to make speed and found a runway in Loring Maine. It's an old bomber base that was closed years back and an organization named Loring Timing Association runs several events there. The runway is 2.5 miles, and they have a 1.5 mile run set up with certified timing very similar to the shuttle runway. Everything I checked appears to show it's a well ran event and many speed records have been set there. Has anyone ever been there or ran there and if so, can you advise me on how it was, in particular what the quality of the runway is like? It's a long road trip, probably 24 hours total of driving vs a little more than a hour but I'm committed to make this happen in 2022 regardless of where it has to be at. Thanks David

I bought one of these for my Sons 1ltr Kia daily driver

[DEMO MAN]

LOL I bet he got a good laugh out of that for a KIA, and 1L??? wow i think the go carts I raced back when I was a kid had more displacement. I'm definitely going to miss your humor in this forum, I've got so many laughs from your "Joke of the Day" posts. If I ever get over to UK would enjoy a meet up and conversations over a few drinks.

Blucifer Revised Trunk Floor 1.jpg

Blucifer Revised Trunk Floor 2.jpg

We laser cut a new floor for the trunk to support all the components such as turbos, intercoolers, dry sump tank etc. The original one made was done in 3 parts and although it was functional, I wanted a cleaner look. We will fit it next week, make new brackets to support everything and then start mounting the components again. Once everything has been mounted, we will disassemble the parts for the various coatings from powder paint, heat coatings, anodized or others. I really want this Viper to be a show piece and fast so it's taking a lot more time to work both of those into this car. Happy New Year to everyone and hope 2022 is good to us all.

Here are some images of the revised stainless steel trunk floor to support all the components. The quality of the fit and appearance of this version is much cleaner than the original one.

Blucifer Turbo Mounts.jpg

Here are the turbos mounted to the new supports, the recessed box holds the battery which will have 0.5" high temp insulation to protect the battery from any heat off of the hot side of turbos. I have this thing about symmetry, and this configuration definitely shows that.

Here is a view with the bumper installed, you can barely see those turbos, almost stealthy
We are currently running hot side pipes, then cold side after that. I expect to have everything tig welded and off to coating within 2-3 weeks max. Still lots to do after that but it's getting there. While the pipes, etc are being coated we will be doing some head and intake work to allow for that big boost needed.

[Steve M]

Love it.

Can't wait to see it run.

I won't ask how much it all cost, but do you have any idea how many hours you've poured into this project?

[DEMO MAN]

If I just estimate the man hours from the previous version of Blucifer which was front mounted turbos to this revision to rear mounted turbos, new intercoolers, fab work etc I would say we have maybe 400 to 450 hours invested. I don't think that's a lot considering a some of it was spent on the design side vs the fab/assembly side. These hours do not include all the efforts put into the pre rear turbo car to include engine work, cage, fire suppression, and a lot more. As to cost, honestly it would be only a guess as I've been more concerned with the goal of 275+ vs do my kids really need a trust fund

What he means to say is that the cost is so high that he doesn't want to reveal it LOL. He knows exactly where he's at in it
Keep at it David, love watching this thing evolve and kick ass.

Thanks for the update on the fantastic build! Do you plan to run diffuser strakes like the ACR? They probably would help your stability at speed.

Loring is where my wife's dad was stationed when he was flying the first B-52s for SAC in '57-58 during the Cold War. Two very long parallel runways - one asphalt, one concrete. It had something like the second-largest U.S. nuke stockpile during operations. It closed in 1994. https://military-history.fandom.com/...Air_Force_Base

We have a custom designed diffuser that actually is longer and taller than the ACR one, comes beyond the rear of the car closer to about where the bumper ends and the benefit is stability. Up on the area where quarter panels meet hatch, we will run vertical strakes that also help with stability. It's a very delicate balance between downforce and speed, big downforce hurts speed but at 240 MPH+ there are wiggle issues that make me drive the car a little bit more than I want to.

Loring's longest runway is 2.5 miles long and we would run about 1.5 miles of that. I know motorcycles have been to over 300 there so I suspect the runway is in really good condition.

LOL, yea I always have been told " speed costs, how fast do you want to go ". That is definitely a true statement. I think $1000 per MPH is about the right number

[DEMO MAN]

Hot side is progressing slowly, but we are getting there. We are close to turning down the side sill which will be quick since it's a straight run. I suspect we will be done early next week with hot side and then move over to getting the cold side done. Using a lot of pie cuts to get the shape I want/need but I will hopefully be able to mandrel bend a lot of them at a later date using less tig welds. Once the hot side is completed it will be coated and wrapped.

Today was tig welding party for the hot side piping. We tacked everything together, made adjustments, tacked it together again and then made a few small adjustments until the fit was exactly what we were looking for. We added some flex into the system after some discussion about movements on the hot side as it heats and cools. Here are a few pictures of today's work, the welds and pipes haven't been cleaned up yet, we would normally polish everything a little bit with scotch-brite pads and fine sandpaper.

The intercooler pumps arrived today. I'm working on location and design of mounting brackets for them along with hose routing. These are each 40 GPM pumps, and the intercoolers are rated for 40 GPM also. Each side has its own ice box and chiller so I'm hoping this keeps those IATs down low for the entire run.
