I have an 82 collector edition. The only upgrade I have done to it is change to a 85-87 fuel pump. I have heard the Renegade manifold will help also. Does anybody have any thoughts on that. Thanks. Bill

A lot of info and discussion on that manifold in the C4 section
A lot depends if you need to pass emissions in your state
yes that's a good idea.what I should have said was to replace the cat .the old ones are not very good. the new ones don't have the restrictions the old ones do.
I would start with the new headers with good flowing custom pipes.But lets ask if you have two put on dual cats?How much can you do ?how much do you want to spend?If you open up the motor I would do the cam also .You also could put on roller rockers.since you went that far you should put on new valve seals.It just keeps going and going.LOL. I would make a plan of how much I want to spend.
That renegade is a real nice piece, for the price not bad for an EFI intake
Couple that wiht headers, a better head mildish cam youd have a strong runner on your hands where you dont have to hack everything up to make it fit.
Bet the renegade out of the box moves more air than a ported stocker
One day would like to get my hands on both to see.
I thought the price was a little high.But the intake out of the box looks good and will out perform the stock or the stock ported intake .would also like to see how it out performs the x-ram intake.But when you change over to this new intake you will also have to balance the tbs.should you also bore out the tbs?If you went with new heads and a cam, this car would run very well But its the cost.we need some guy with the time and money to do one upgrade at a time ,then dyno the car .seeing the numbers will tell us what we get for each upgrade.
Installed a Renegade on my stock 82 with 115000 miles on it. Had upgraded to 85 fuel pump and Magnaflow mufflers on stock exhaust. Right away I noticed it would pull better to a higher rpm. Don't like really beating on the motor with this many miles on it but did make a difference. Here are some pics of the ports and how much bigger they are.

K Redliner-
How was the swap? Any problems with any of the sensors adapting to the new configuration?
Also, did you just swap out the stock mufflers for the manga flows- so not true duals? How do you like that set up?
Had no problems with the swap, everything bolted up with no issues to my surprise. Just went with the magna flows hooked up to the stock exhaust. Replaced the cat with a stock one because the old one was spitting pieces out. I like the magna flows, does not drone and only gets loud when I get on it.

Bought the ones from Corvette Central, they were ready to just bolt on. Don't remember the number but they should be in the catalog, was probably 8 years that they have been on.

Hi guys, Tom here from DCS. What do you want to know about the Renegade? I do know a little about it. Jus sayin'.
I can tell you that Jim and I both ran the Xram a long time ago and it was better than an un-ported stock manifold. However, when we finally decided to build a better "mouse trap" as it were. I got another 22hp to the rear with just a swap to the Renegade from the Xram. The tune at the time was optimized for the Xram. After the swap with further tuning out performed the Xram by leaps and bounds. This was with my motor which is a 383, not a stock 350.
If you look at how the Xram flowed, it was horrible really, especially if you know about fluid dynamics. Just take a look at a side cut away view of that manifold and you'll see.
You should have heard the comments when we brought a stock and Xram manifold to the manifold designer when the project first started. The comments on how the Xram flowed was rather funny.
The Renegade could perform a lot better if we could have gone up in direction, but with that it wouldn't fit under the stock hood of a corvette for sure. We did look to see if we could change the design a bit for more power, but it just didn't work in the overall plan/design spec.
So, ask away if you want. I'll help as much as possible.

That is huge for an intake
Have done similar with TPI intakes but good gawd does it take a lot of work
If the ports could have been taller with some taper sure you could get more volume. think its a great piece....peeople complain but how many are making pieces for those cars? Its a good thing. If I owned a CFI that would be the first mod
Member Shinobi-x used to run an 84 yrs ago at LACR with my 89 stock with a catback 3.07 gear..he had a catback 3.54 and Xram. same result every time. Hed jump me some then by the finish line id just barely skate by him. If he had the renegade Id have lost everytime. Not bad for a stock CFI. I was running low 14s at 100ish
13.9 if corrected for sea level. That woulda been almost a 2 second drop for him, dont doubt your claim sounds about in line
Not sure why you want to try making a speed demon out of an L-83...but do what you must. You could just remove all the stuff on the outside of the engine, plus cam and heads, then put on some good stuff. Otherwise, you're probably just wasting your time and money.
Getting another 20 HP from an intake manifold change seems useless to me. Lot of trouble....little change.
