1998 S70 T5 M N/A intake & 960 throttle plate

Post by shaker_chi »

Couple weeks ago I picked up a 1994 turbo intake that was bored out with a n/a throttle body with the 960 plate. I had to tap a line for the PCV hose on the end of the intake manifold and tap a port for the fuel pressure. So after doing all those modifications I finally installed it this weekend. I took it on a 100 mile trip today and here are my thoughts:

1. I definitely felt more torque below 3,000 rpm's. Now this may change from I've read.

2. It did seem like the engine ran smoother and it could "breathe" better, it idles at around 950 rpm's with no loping or surges.

3. Here is what impressed me: I set the cruise at 65 MPH for the first 50 miles and I got 34 MPG, on the last 50 I set the cruise at 75 and I got 30 MPG. This is about a 10% increase from what I was getting before.

Overall, I would equate the torque to modifying an N/A throttle plate with the 960 (I did this as well on my 94 850 manual). Not sure if there is really anymore horsepower, some claim an increase of 10HP, but I wouldn't hang my hat on that. I am glad though I could get some more MPG. We'll see how it does in city driving since I'll take it to work the next few days to see what happens.
