Trying to take the blower off, once the assembly was installed on the engine, would be a nightmare. I had my doubts about eliminating the dowels until I was threading in the bolts by hand. There isn't any slop. And you'd still have to get under the plenum in order to tighten the driver side rear bolt, as much as it might be slightly easier to do it on a bench. Accessing it from the rear would be cheating.I was thinking would it be easier to remove the lower intake manifold from the engine and attach the s/c and fuel rails on a bench. Then install as an assembly. Then the dowels could be used and the RTV would be much easier and no special wrench would be required. Just a thought.
The GT 500 engine location in relation to the firewall vary about 5mm. Its best, instead of denting the firewall, to loosen the K-member and slide the motor forward.
We use .025" spark plug gap.
Thanks
Dustin(?), while the effective weight distribution change via shifting the K-member forward may be negligible, I think I'd still do it the same way were I to do it again. If I had a lift and the time to loosen everything, and then resquare everything - maybe. I'd just rather not increase static caster and instead keep the engine as far back as possible (this thing is a pig enough as it is).
But hey, this was my first GT500/2.9 Whipple install. After as many as you must have done, I'd probably come to the same conclusion and just do it the way you mention.;-)
Bottom line - you guys make one hell of a blower kit. The fact that FRPP teamed up with you and throw their ProCal into the mix only serves to make it that much better. Thanks for reaffirming the .025" spark plug gap. It seems to be on the small side, but hey, I'm certain there is sound tech behind the recommendation.
One question - upon engine shut off, there is a brief purge or "hissing" sound for about 1 or 2 seconds (you can it hear it at the end of each clip I linked up above). Is this just excess blower case pressure upon shut off? Where is it venting (back out of the intake tract?).
