Looks great Greg!!!! Hope it performs as well as we have thought it will!!!
 
Very nice... Cannot wait to see it go! Good luck Greg.
 
Slick way to tie the scoop tray into the turbo inlets. Nice work.
 
Looks good, Greg.

Question : Why the longer exhaust distance from the head to the chargers? Seems like a lot of surface area to deplete thermal energy that could be used to spin the chargers. Or is this irrelevant for the turbo in the bottle?

Edit: Those long tubes do look neat though. :D

Working with pulse, using the merge collectors. I would have liked it to be closer, but we did the headers that way to possibly run a Pro Charger at some time in the future.
Car weighs 1745 with me in it. Still need to add the weight of one nitrous bottle.
 
Good Luck. I hope you dont fight convertor issues, are you trying a coan 10.5" first. Just in case, I,ve been dealing with Dennis Reid and he has his chevy bell now machined to accept a 12.5" just cant quite get a 13" to fit. Your lock up and efficency may not be as much issue as mine was with increased rpm. But Coan couldnt get it done back then for me either..... in a 10.5" cover that is. Hope it works out good for ya though.

I have a lot of experance with the small converter and anything tighter will shake the tires . I plan on stalling about 4700 to 5000, I don't plan on a lock up.

Charlie Stewart Race Cars built me a chassis similar to what I would run in A/ Dragster Automatic. Which is a 1500 hp 1700 lbs car that runs 6.40’s. It’s a 255 inch slip joint car, with all of the weight savings options. I have 2 sets of tires to run 33.5 X 16 for bad tracks and 33 X 15’s for good tracks.

Charlie builds about 15 cars a year mostly Corvette roadsters that with the same running gear as my dragster would weight about 2100 lbs. with driver.

I would love to see a chevy Dmax in a Chevy 63 Corvette
