Just an FYI: CST5 runs out of steam at 31-32psi with a peak rpm of 7500rpm. This makes 530whp with some taper down above 6500-7000rpm depending on headwork. I've seen this power curve repeat itself a few times on well sorted MS3s on a dynojet or other dyno with same dynojet equivalent...

Safety First! Following the NHRA requirements, I have been building a firewall enclosure for the Radium FCST System in the back of the car. Per NHRA you can use 0.024" steel or 0.032" AL sheeting for the firewall. Per my local NHRA tech inspector, the level of "sealing" needs to be "pretty...

The rocker arm crossmember got some added bracing welded in over the weekend. I think its a bit overbuilt, but I'm ok erroring on the overbuilt than under built.

One more post because this is a fun one! With the staging brake location I cannot easily use the OEM center console and thus no cup holder. So I made my own that doubles as a normal cup holder and a Milwaukee Packout Mug holder...it locks in!

I also worked on alot of electrical and fuel plumbing recently: Electrical: So I moved the battery location to passenger side in front of the rear axle centerline. This did not requirement to change my cables much and helps with weight distribution a bit more being passenger side. The...

More updates and lots has happened: Did a bunch of welding (these are not final but are the images I seem to have). By no means am i a professional or even great welder so they are not pretty but they get the job down and will get cleaned up and painted either way.

More updates from lastnight: A buddy and I prepped the trailing arms for the pushrod mounts last night and got them tacked in place. The cleaning and paint removal was kinda of a pain because it was just difficult to get in the tight corners but we got it handled. Currently tacked in...

Spring will be on the damper itself. Makes the preload adjustments much simpler along with other things. The pushrod uses LH/RH spherical rod ends so that will be the height adjustment for corner balancing.

The subframe did not actually support the weight. the top of the spring rests against the "chassis rail" and the subframe is just sandwiched between them. Tubing is 1.75x0.120w DOM and end plates are 0.135" 1008 I should also note that the crossmember is nested in the endplate, not just face...

A question to the Forum Engineers: Additional bracing for the crossmember - I am planning to add bracing along the blue lines in the image. This is mainly to support the composite forces pushing downward in the center of the crossmember. - I did specifically design the dampers at a shallow...

Next update from the weekend: The rocker arm suspension is no longer jsut a cool idea and CAD model! Firstly, I had to remove the brackets that are spot welded and stitch welded to the tops of the shock towers in the rear of the car. This provided me access to the actual top of the shock...

A couple updates over the weekend: Finished up some assembly of the Radium FCST (Fuel Cell Surge Tank) system. Added the second fuel pick up in the surge tank for another external pump (running a MagnaFuel 525 for PI and a Quantum 380 for DI). Setup the "hellcat" 525 in the lift pump location...

What a great Monday! Some goodies arrived today (both expected and not expected). Little box is an AWD controller that integrates with the ECU and CAN data. Has its own software and programming logic. Tote is a spare T-case that will get billet bearing caps Fragile box is a surprise pack...

Nice build! Let me know you want to talk wheels and tires...I've tried some things

How hot does it get? Need gloves after the engine has been running?

From what I can tell: the driver side case half of the transmission is the same for MS3 and MS6. Therefore the TMM and shift cables bracket directly transfer like OEM. The passenger side case half of the transmissions are different. The obvious difference is the Transfer Case connection...

Things are starting to happen! It actually has a transmission now! Trans and T-case went in pretty smooth. Intermediate shaft and mounting block are also in. Looks Great. The oil drain is also very tight but good. I thought ahead with the Xona turbo install and got a oil drain...
