Final dynotune after nitrous install complete.
Stay tuned for final dynotune and track numbers. She's been down over 3 years. Nothing was thrown together. Every factory gauge works and even cruise, air, heat, factory Bose radio works. I used dakota digital box to correct speedo and tach for stock dash. I used a dakota digital box for the cruise control. Factory LT1 computer has been removed. I had a shop do all the heavy stuff but I did all the research and final wiring. Basically the shop got her limping and I have been working out all the bugs and updates. I've had her apart since I got her back doing the brakes, suspension, exhaust-all tig welded, wiring, radiator, a/c, widebands, ect! Pm me if you have any questions.
How did you get the gauges and abs to work? Also, what stub axle did you go with?
I ran dual sensors and dual computers. The only thing that doesn't work is the miles per gallon...I can live without that. I pulled the factory computer trying to get rid of clutter and redundant wiring. I went with dakota digital modules to correct mph and tach and another one for cruise. The abs light isn't on but I haven't gotten on the brakes yet since I just got the parts to install the rear wilwoods! Will keep you posted. I don't drive the car in the rain so I really don't care if it works or not. It's a crude system at best IMO.
Wow engine looks and sounds mean. I think it would fly in the 1/4 mile.
Must have cost a small fortune
Thank you and I can't wait to get her all finished for the 1/4 mile!
Actually a medium sized fortune. At least $40k not including the car....at least. I got some of my $ back selling drivetrain. I will be selling the brand new zr1 style chrome wheels with new nittos on front 275 and 100 miles and 3 races on rear mt drag radials 315. I'm still contemplating on what tires to go with on my new Fikse. I know what size I'm just not sure which brand.
Thanks....that was the day I did my museum delivery on my new zr1 and happened to buy that Viper up there too. I actually had a pr!ck stop in his corvette and ask if I was lost. I said no I'm picking up my new zr1. It was a foot in mouth moment for him. Like it was his business if I like more and own more than one type/brand of sports car! There was a mix up on the museum delivery and the car came to me instead of museum. So I had nothing else to take pictures with. I didn't think of it being ironic at the time.

Awesome
Love that gen of the Viper. I see you're in DFW. Let me know if you go to any car events, I'd love to see the C4 up close
This is totally awesome work. Thank you for using the c4 as a basis for this!
One question is jumping out.... Money is obviously not a factor so that's out...
Why are you doing nitrous vs. boost?
First of all thanks for your compliment. I love my c4. I started this project because my c6z would outrun it and my zr1 would murder it. The c4 ran 7.2 at 98 with the 383 lt4 motor na at the time. I have been using nitrous since early 90's and have always liked it. Everyone I have every known personally have had troubles with boost at very high hp levels. I personally have owned two new Camaros with Maggie blowers and they were great and reliable with 600 hp. Remember I started this project four plus years ago and 1000 plus hp wasn't as commonly easy and reliable as it is to make now. Buy a gmpp 376 15 and a big kenne belle and 1000 hp is commonplace. I can't tune so I have to have that outsourced but I can set up a stand alone nitrous kit. I guess you can just say it's personal preference. Plus you don't want to boost the high compression, big bore lsx454 from what I have read. My goal is 1000 hp so a 250 shot, which isn't a lot, should get me there. The car weighs 31xx so it should scoot.
