I was heading back from my night class, and since i know where there are several areas of high speed, desolate, and relatively new pavement, I decided to do a little testing. I purchased my 1987 9000 Turbo last October for $500 just to get me by a few months, but it keeps enduring. I've slowly been improving it and doing some mods, just for fun really, since I've had many Saabs. Ironically, the one I purchased just to get me around is the one that has been the most reliable.
The List:
+Removed AMM Screens
+R42/40 APC Resistor mod (Courtesy: 900aero) with agressive boost build and limit
+2 1/4 inch straight pipe w/catalytic converter
+Vacuum Advance DYI Mod
+Bypassed Vapor Recovery Canister (I'm not sure this does anything)
+Cone filter with tube directing air to filter
+Tested at 14 PSI spike with retard settle to 11.5 PSI (actually much more arbitrary, but this is an average using an extremely accurate industrial gauge...thanks Colin!)
I've also installed:
All new motor mounts, vacuum lines, brakes, a wheel bearing
Here is what I got for performance, remember that this isn't really the most precise scientific way of going about testing. Note all the variables in each test. I am assuming people reading this post have enough backround to get the idea.
23 Degrees F, 83% Relative Humidity, 30.17 IN/Hg Barometric Pressure
Dunlop Sport A2 tires worn to ~95% (nearly bald), Width 195, Stock 15" Rims
First Run; clean, new Asphalt, Slip at 3500rpm
6.48 Seconds
Second Run; clean, dry older Asphalt, Slip at 2700rpm
5.42 Seconds
Third Run; new blacktop w/some salt residue, Dump at 3000rpm
5.76 Seconds
I think what I've learned from this experience is that a modified B202 9000 Turbo on worn all-seasons in the middle of winter is the most difficult car to launch in existence. The engine is incredibly peaky, grip is poor, and there is so much power (first gear is a joke) coming on at once that it is hard to tell when to shift, especially seeing as the car is fighting and uphill battle for traction all the way to 60 in second gear.
I also did a test to see how long the car takes to accelerate from 55-75, since it really shines at these speeds. From constant throttle (probably -10 psi vac) at what appeared to be 3400rpm I timed a 3.24 second sprint.
All in all I have to say that while the times were all over the place, the car is definately quicker than my stock 944 Turbo. I guess this is the reason that I love old Saabs so much. Not to mention how comfortable it is!!! This experimentation and speed have kept me from purchasing an E36 325i coupe at this point, and may keep me with the Saab badge with hopefully a newer 9000 on the horizon.
Thanks, Evan
