Dustin,

I am still in the gathering info mode, but I would like to run twin turbos.  All the fancy math with exotic inputs seem to be geared towards finding optimum performance at all operating levels.  My simplistic mind says - I don't care about idle, off idle or mid-range responses, I just care about WOT at top end.

With that in mind, it is reported that a turbo from a late 80's T-Bird can spool up 13-15 psi on a 2.3L all the way to redline.  The Y-Block will have 4.2L and a pair of those T-Bird units would be just enough overkill to wastegate them back to the max sealing capability of the Y-Block heads.  Sounds like a start anyway...............

i wish i could help more with the turbos.. all of my experience with them has been on fuel injected vehicles so i wouldn't have a clue how they'd perform on a carbed setup.. although the Garrett T3/T4 hybrid i had on my Subaru WRX was about the best turbo i ever owned.. that thing was awesome.. barely any lag whatsoever and held boost throughout the RPM range.. Did you decide on a twin or single turbo set-up?

Seppo,

Is bigger really better?  I know it would look better!  Please keep in mind that we will only be running 258 cu. in.  I have read your turbo articles at least three times and I am filling my head with as much info from books, internet, and experienced racers as possible.  The possibilities include draw-through/blow-through carb, draw-through/blow through mechanical FI (EFI not allowed in the class I'm trying to compete in).  Selecting the right turbo isn't easy while trying to match the volume of air being moved with the maping and A/R ratio.  It's like the old story, the more you know, the more you know you don't know.

Ketterbros,

Yikes, perhaps Bill was thinking that it would be "stabilized" in flight!!!

Todd,

The pleasure was all ours, you are welcome back anytime.  Thanks for all the insight and recommendations on the Mustang II front suspension.  Good luck with the bird, I know it will be a killer ride.

Alan,

There are four basic classes for a sedan like the Comet.  Production (bone stock aerodynamically with an engine that was available from the factory in the year of the given car), gas coupe (pretty much the same as production, but requires an engine swap to something not available from the factory), altered (mainly an engine swap, covered grille and headlights with a few other mods available) and competition coupe (chopped top, extended wheel base from the cowl forward, full belly pan and an engine swap).

So with the Y-Block, it will have to run at least in gas coupe, which is exactly where I plan to be.  The fender skirts are good thinking.  I have only noticed one set and that was on a Corvette.  The rules do say no streamlining, but it doesn't say you cannot run fender skirts, you might have something there.  Most of the guys agree, if it doesn't say you can't, then you can.  I am going to follow up on that.  My intentions are to run a narrowed 9" to stay inside the body.  And yes, the reason I picked this one is the same reason I picked the pickup.

Are aero rear fender skirts allowed? and inset the rear wheels? Also how did you choose this body style? Anything like your pickup choice?

Gonna really be cool, go Charlie! and yeah, y not a yblock! did it have to be available in that? (class) or is that irrelevant.

Bill,

I'm all for "stabilize".  Tell Reed I need help on the turbos........

Dustin,

I'm trying to make this a "Gas Coupe" (if you make to many mods, you will be moved up to altered).  The gas coupe rules only allow the following body modifications; front air dam/splitter, hood scoop, radiused wheel openings for tire clearance and minor chrome trim removed.  Currently there is discussion of allowing a spoiler.....we'll see.  I will do all of these mods except for trying to keep the tires under the stock wheel wells.
