Callaway differences - a little help please!
Guys,
starting research on purchasing a Callaway C4 and haven't been able to explain/understand why some seem to have the NACA ducts in the hood and some dont.
The intercoolers all seem to be able to draw cold air from the base of the windscreen...
BTW are the hoods unique to Callaways?
Not sure what the NACA ducts are for then?
Perhaps a point to an informative web page with comparisions between the years..
Happy to listen to opinions as to what Callaway (87-91) is the most desirable and why..
Keep in mind my budget wont stretch to the Sledgehammer
Thanks for any and all comments. much appreciated.

The 87s are the only ones with NACA ducts. The have the smallest turbos and lowest power but are the easiest to get into from a price stand point.
The 88-90 had a flat hood.
The 91s have the "blister scoops". Some of the 88-90 cars may have had the blisters installed later.
88-91 had the bigger turbos and made more power.
None of the cars drawn intercooler air from the cowl or windshield. The NACA ducts feed the intercoolers on the 87. On the flat hood cars there is ducting that runs on the bottom of the hood and feeds from the stock air cleaner location.
The blister scoops on the hood of the later cars feeds the intercoolers.
The 91s are probably the most desirable b/c they have the highest power and were the last production year. They also typically cost the most.
However the exceptions to the rule would be any special edition such as a 100+ car that would command more money despite the year.

SurfnSun,
thanks for the quick reply!
Lots of info in your post, to confirm are the hoods unique to Callaway's?
There was an owners page that seems to be gone now... www.callawaysownersgroup.com any idea if it was replaced by another page?
I've seen a couple on Ebay and some for sale on here - any other suggestions to look for Callaways for Sale?
Seems as though places like Corvette Mike etc are all overpriced - probably adding a big mark-up.
Cheers

The 88 with Dymags is a smokin deal. 
The hoods are stock units modified by Callaway. Several copies out there but nothing exact.
The COG website will be back soon, I'm working on new hosting but have been without power for 5 days due to the hurricane. Currently posting from my iPad. Once the website is back up there are plenty of underhood pics to look at.
Let me know exactly what you're looking for and I might be able to help

Is this advertised somewhere??
Hope you guys are OK and the Hurricane hasn't done too much damage.
Pretty impressed with your "Corvette commitment" to post without power!!
I'm gathering as much info as I can - found a cached copy of the buyers guide from the owners group web page and would be looking for :
Anything else I should be looking for or be wary of?
Cheers

I'm gathering as much info as I can - found a cached copy of the buyers guide from the owners group web page and would be looking for :
- A B2K, not a "Direct Conversion" car
- As low a km as possible
- I think either 87 or 91 as I like the "look at me"factor of the hood scoops/blisters, slight preference to 87 NACA scoops.
- Color? Blue or the Emerald green
- Manual (Stick shift)
- Aero/body kit?
Anything else I should be looking for or be wary of?
Cheers

Some Specs, I've managed to discover- perhaps someone can fill in the blanks for me:
Year/HP/Torque
1987/345/465
1988/382/562
1989/382/562
1990/390/562
1991/??/??
BTW have come across quite a few old "for sale" ads that had 1989/90 Callaways with Blisters on the hood.
Were all Callaway's supposed to have the Dynamags, or were they options?
Have come across this one, looks a bit rough and needs work, but cheaper than most.

Same car for sale on this forum for $14,900 OBO
Cheers

There is a Polo Green 90 Aerobody 6Speed for sale in Michigan. 35k miles, big wonderbar ($2k upgrade) and good price at $25.9k.
http://www.cauleyperformanceautomoti...inventory.aspx
The 91 specs were 403hp/575tq. Regarding the older ads, the blister scoops were considered an upgrade and many of the 88-90 Aerobody owners opted for that upgrade post production.
As far as the Dymag wheels go (not dynamag), the 87's could have come with a 16" stock wheel, 16" Dymag, or some had retrofitted 17" Dymags. They were standard from 88-90. Some of the 91's have Dymags, but then some wear the 17" OZ Futura wheels. Both are considered correct.

Great! Thanks for filling in the last bit of info.
The Callaway looks a good deal - am a little confused as to why the specs on engine performance reference 1989 #'s, but the car is advertised as a 1990?
The engine reference is a L98....was there other choices?
I'll drop them a line..
I'm convinced now...got to have the Aerobody - no point in being a sleeper
Thanks again

I grew up in the next town over from Callaway in the 80s( East Lyme CT) and I used to see them going on test runs without the clamshell hoods on. I used to work at a gas station and one pulled in for some gas without the hood on and I about crapped myself with exicitment
So someone please buy that 90' aerobody and save me from myself
What is a wonderbar. Is that the same as the 100+ setup?

Yes, you could get an lt1 that was a 383 and rated at 440hp if I remember. Might have a whole range of power on them actually. They were not turbo cars. They were called supernaturals.
There were also ZR1 LT5 being done

but they were not twin turbo?
Was there a twin turbo LT1? or were they all L98's (twin turbo)
I should've been a bit more specific - I'm looking for the twin turbo Callaway produced from 1987-1991, as the B2K option from Chevrolet.

Nope, the TTs were all L98 based, plus a handful of LT5 based cars. The LT1s were all naturally aspirated, hence the 'SuperNatural' name.

I haven't seen the Michigan car personally, but I know it was not driven in the winter time. I doubt rust is an issue.

The Wonderbar pictured here is for a 91 model car and that is the stock peice. The 88-90 cars had a side feed from under the passenger headlight, and the upgrade increased the volume of the front side opening on the Wonderbar frame section.

However, I have seen the car in MI and it is pretty clean
