    mild backfire?

    My car has been doing the same thing only when it is cold & I have been running the 93 octane program from Doug for a couple of months. I just switched to the 91 octane program to see if that made a difference, but it's too early to tell. I did hear the popping at idle again this morning but...

    Something odd :-?

    I just drove my car from CT to VA and back. I had to fill up four times in all, including when I got back to CT. I got 28 mpg on the two tanks on the way down to VA and that was running without the cruise control most of the way and going as fast as 80 mph at times. I the way back I decided...

    Wiring Open Secondaries

    My experience with open secondaries is similar to Paul's. I first used tie wrap but could not get it tight enough to hold the butterflies open all the way. With the tie wrap still in place I wrapped a piece of clothes hanger wire from the IMRC cable bracket to the arm of the butterfly shaft &...

    X-Calibrators work for '96-'97 SHO's

    I just installed mine last night and have only put about 20 miles on the car so far. At very light throttle, there is not too much difference, but the shifts are still a bit faster and they seem to come sooner than before. At half to full throttle, the 1-2 upshift is much harder and faster...

    X-Calibrators work for '96-'97 SHO's

    My cable broke. I saw a few posts here & on V8sho.com where people had wired the secondaries open so I decided to try it. It doesn't seem to make much difference one way or the other. It does seem to make it idle a bit rich, but other than that it just saved me the expense of a new IMRC...

    X-Calibrators work for '96-'97 SHO's

    I just emailed Doug a confirmation with my CC information, so I should be added to the list. :thumb:

    Borla Question

    2.25" Offset/Offset Borlas Borla has offset/offset mufflers in their ProXS line - these are not available at all Borla dealers. Huskers High Performance has them online for $85 each plus shipping. The part number 2.25" O/O is 40351. They show up on eBay every once in a while, but the bidding...

    Front sway bar question

    If I change the front subframe bushings myself, will the front end need to be aligned after? Is just a matter of getting the subframe back in the same position to keep the steering wheel straight?

    Exhaust Questions

    This is an article about an active exhaust butterfly that could be used to regulate exhaust backpressure as a function of engine rpm or throttle position. This could be used to reduce noise at idle and cruise (& potentially improve low-end torque) while still allowing increased peak output from...

    IMRC Repaired

    It's been several days with the butterflies wired open, and I'm quite certain that really like it better this way. The MIL has been out for days & from what I read here and on V8SHO.com, I know I won't be seeing it again. I have no trouble starting or idling & we have had temperatures down to...

    IMRC Repaired

    My MIL did go off on the way to work this morning. I made sure to park the car and shut off the ignition several times during my test drive last to create the required 3 driving cycles. Looks like it worked. Power is restored and no more annoying light. It does feel like there is a slight...

    IMRC Repaired

    I removed my IMRC control last night (the cable was broken) and wired the butterflies open. I took it for a test drive, but it was still warm from the evening commute & it was about 50º here so it seemed to run just fine. It's still pretty warm this morning, so it will be a few days before I...

    IMRC Repaired

    Paul, Does keeping the butterflies open all the time result in a rough idle or loss of low rpm torque? My IMRC stopped working last week and I'm wondering if this is a viable option at least for the short term. I now that you have a significant number of modifications into your car, but...

    1999 SHO Transmission Shudder

    My 97 started to shudder in 1st gear only last Friday night with about 88kmi on the car. It quickly progressed into 1st gear slipping at anything more than light throttle. Given that my problem is only in 1st gear, I think it is the low one-way clutch that has gone South since this is the...

    SHO V8 reborn

    I also read the Car & Driver article and they did say that XC90 engine was based on the SHO 3.4L V8. But today I got the October edition of Ward's AutoWorld which has an article on the new engine. The article says: "Volvo insists its new 4.4L DOHC V-8 is not a modified version of the 3.4L...
