Saab 900 Turbo Holset HX35 - Mustang dyno at altitude

Recent STI vs Evo shootout at Ziptie Dynoworks, in Salt Lake City, UT. Only changes vs the last time, on a Dynojet, are in the tune. At altitude, so the uncorrected numbers much lower just as expected, as well as the "Mustang" factor. Pleased with the results, despite the above.

Saab 900 Turbo Holset HX35 - vs Subarus
Friendly races on some empty tracks in Mexico. Completely computer simulated. 1997 Saab 900 turbo Holset HX35, 28~psi -vs- 2002 Subaru WRX, VF39 2007 Subaru WRX STI, Blouch Dominator 3 -vs- 2006 Mitsubishi Lancer Evolution 9, bolt-ons





1995 SAAB 900 B204 TB2569 stage 3 dyno run
Saab 900 2.0 stage 3 Dyno run. Nearly there, 240hp 245 lb.ft. Boost is extremely stable but spiking initially and settling slightly low. Low HP/Torque attributable to the heatplates that sit in the inlet path on the head. Mods: T5suite stage 3 remap + 2.5" decat downpipe + forge recirc valve + taliaferro poly engine mounts + maptun silicon hoses + viggen Intercooler Since taking control of the mapping and tuning it live, adjusting ignition timings and Boost control, it ran 256hp 264lb.ft in 2012. Only change to the hardware was replacing the 2.5" decat with a 3" maptun downpipe with race cat. Once the heatplates are stripped out, I expect that figure to rise to approximately 275hp 275lb.ft. All three Dyno plots compared: (stage 1 vs stage 3 v1 vs stage 3 v2) https://www.talkstuff.net/ipb/uploads/gallery/album_303/gallery_44179_303_2 04131.jpg





~ 700hp Turbo Saab, 312kmh (194mph)
Extreme turbo Saab + 300 kmh Many viewers have misunderstood this video, so I explain it a little: -Speed at finish line (1mile/1609m) is measured. Time is not measured. -First Saab does 1st and 2nd gear with ~half throttle. Second Saab has limited Boost for 1st and 2nd gear. - three extra seconds between 0-100kmh typically means ~30meters wasted. But three extra seconds used in speeds close to 300kmh, means almost 300meters wasted. Here is equally powerful RWD cars (if not even more HP's) These RWD's are a lot faster between 0-150kmh, but these Saabs are faster from 150kmh-300kmh. You get the point when you compare speeds at finish line. http://www.youtube.com/watch?v=urWWdomnncw -A Saab 9-5 driver pushes a little too much throttle @3rd gear and looses traction. He lifts a throttle and pushes it back, but too much again and then he gears up 4th, a bit earlier than planned. (optimal is@205kmh). Earlier that summer I broke one gearbox when pushing too hard on 3rd gear. With new gearbox and at later event, I drove very gently on first three gears to avoid breaking it again. I pushed WOT for the first time on 4th gear @ 190kmh. You can hear it clearly on following video. Engine tone changes totally around 200kmh. Incar video is from 299kmh pull (at 1 mile race) Something happened to camera during the run. So I didn't get any incar video from a 305kmh pull. To see that run from the start line, please see my other videos. Here is incar video until camera dies. Start is @1min. http://youtu.be/M4NNX4Ygnwc
