Dirt cheap for a good SPG without the mods. Wow. Just wow

Me too. Prefer the bull nose of my 86, but this build is very impressive

TIL there is a land speed race in Arkansas, Too bad it is in the other side of the state from where I am and 10+ hours away. 

 

Pretty sweet car and build.

I'm not sure you'll ever find another built Saab that'll do 170, especially one that's as cool, and special as an SPG. If I had some spare coin and no SPG, I'd jump on it. It's cheap and these are appreciating

I just bought a one of 1000 globally Mitsubishi. (250 a year for 4 years) 

A 170MPH SPG is a pretty neat car no doubt. Need to clear out 2 other cars to make room for anything else.

Very impressive.  How do you keep the transmission together?

Good question. The Saab 5 speed isn't the most robust

Shredded 2 transmissions. Broke in third gear at 6,000 rpm before installing Quaifle ATB  limited slip differential May 2011 Maxton,  NC.    2nd transmission  broke in 4th gear  at 6,200 rpm  at 32 psi boost. May 2015  Wilmington, Oh.  Current transmission is out of a 1991 900 non turbo.  Developed a 2-stage boost using 25 psi in the first 4 gears. 5th  gear 30-32 psi   5th gear drive is straight through main shaft so no load on countershaft.  Electric solenoid activated by the red switch  on panel forward of the shifter activates 5 gear boost. Two  adj. regulators in glove box sets boost psi.  So far, limiting boost in first 4 gears seems to work.

Yes,  Dan has too many SAABs  no room for another one. Mainly interested in Bonneville. This car would not fit in a competitive class at Bonneville. He is  a good friend  over the years and we have worked on many parts for SAABs.  He drove this car at Maxton to get  his ECTA licensing runs  in 2010.

I love this build,  especially how you guys have been dealing with the fragile gearbox. Ever thought of doing a 4 speed and an electric overdrive of some sort

 Not aware of a 4-spd w/overdrive that would mate up to the SAAB engine and fit the chassis. Considered a  SAAB  4-spd rally  box  1:1 mainshaft out of Europe. Very pricey!  If I were to develop further would convert to rear wheel drive,  more horsepower and safety eqt. to run 200+ mph .   It ruin it as a street car so let someone else acquire  it and have the fun.
