@alex-heavens Nice photo! That must be one of the very first few built. As far as dropping out the bottom, I find the engine surprisingly difficult to R&R. I unbolt everything, get the engine chai...

Jim, Maybe this will be of use:

@alex-heavens Yes -- the old chassis has the rectangular bolt on top bracket. And both are low hoop. (I've still got the old chassis -- I can't bring myself to throw it away) About the pressures, I wa...

@alex-heavens Current working pressures are between 8.27 and 10.69bar. The North American MoTeC/Geartronics engineer is off doing double top-secret updates to the shifting setup, so it might change. ...

@alex-heavens Yes, my MoTeC setup does exactly that -- calculates the new engine speed based on current speed, braking decel, and gear ratios. If downshifting would overrev the engine, the downshift ...

All the wiring and plumbing is done, testing looks good. Sebring on Saturday! Attachment : UNADJUSTEDNONRAW_thumb_1ac4.jpg Attachment : UNADJUSTEDNONRAW_thumb_1ac3.jpg

Right: the valve block failed due to a leak. The Geartronics valve block is rated at much higher pressure, and so we can now run the whole system at higher pressure which will increase its reliability...

@alex-heavens The current engine is an RPB with unknown hours. I've got an RPA on the shelf in the same boat (gonna refresh it in 2021 then swap it over). Your TMT idea occurred to me as well. The cur...

I've got 4 never used Hoosiers for the rears... no idea how old they are (probably 5+ years). You can have them for the cost of shipping.

@stephen Thanks! It's track-proven now. Shifting with the RDS Geartronics firmware and MoTeC M150 is amazing. I've been able to tune any bank-to-bank differences, the car starts immediately, and I'm s...

Call Spring Mountain, and they'll send you the freight box via UPS. You'll have to figure out how to put it together, but it's a simple job. Removing the engine, draining all fluids, and getting it se...

Wow, that Comatra system looks like a good solution. Any idea who might retail it here in the US?

@vec110 Any interest in an '07 SR8 chassis (#42)? Never wrecked, located in Florida. I don't know what all is involved in converting it to an SR3, but I'll make you a smoking deal on it. John

AN is indeed Army Navy, and came about during WWII as the US government designed a standard thread, taper, and hose size to help get compatibility among all the various American manufacturers at the t...
