I just bought my C5 and plan to add a supercharger. However, if I opted for minor mods and no supercharger what kind of horsepower and/or quarter mile times (or speeds) could I expect? I would at least add the following:
Corsa Indy exhaust
Donaldson Blackwing
Kirban shifter
160 degree thermostat
and possibly long tube headers
I would say with all the mods you listed (including the long tube headers) you would be around the 330-340rwhp range and could probably run 12.7-12.8 1/4 mile if you are fairly decent at launching it.
If you are interested in pricing or details about any of the mods you listed, feel free to drop me an email.
That's a pretty good estimate by Matt. I think you'll like the Kirban shifter better than any other mod you do, and you'll gain the most power from the headers. Good luck! :cheers:
I run consistent 12.8-12.9's at 111-113 mph with just the Vortex, PRT's, and 160 stat/HPPIII for fans as long as keep my 60' time 2.15 or better. Long-tube headers/drag radials should put me even deeper into the 12's.
