New C5 owner here. 128k on the clock, 3.15 rear end. My question is, what would you guys do to refresh and wake this girl up a bit? I know it needs rocker up grade, all fluids changed n obvious tune up, aside from that stuff transgo, lt, etc?? I know you guys know your stuff and I also know how to search threads, so for the people my questions may bother please look over this post n go be a donkey elsewhere!! I'm looking for this to be personal and to make lasting friendships and a plethora of knowledge. Corvette is about appreciating the heritage, not crying about someone asking a question a thousand times!! And the negative replies just shows how ignorant you are! You could of easily kept scrolling or added your knowledge, instead of crying. What are the babies gonna do, if grown men are crying and whining?
. Thank you in advance for everyone's help and I hope my lil rant wakes some people up!

OK... you want help but lambast people who haven't even answered? You complain and whine because you think posters might complain and whine?
As for the actual question; what's your budget, goal?

 

You already have the 3:15 rear end so that is pretty good. Headers, intake and a tune would wake her up for not too much money. My Z51 '04 is plenty peppy just stock. There are very knowledgeable folks on this forum and are willing to help if you give them a chance. Good luck with your project.

 

Grantv, I've read a ton on this sight n almost every thread has some one giving crap for asking questions to gain knowledge and I don't think people deserve crap for not knowing something the next guy knows. If it don't apply, let it fly!
Budget isn'the the concern really, I would like to do something with LS3 over the winter. You n everyone else is gonna think I'm crazy probably. My boss has a Hellcat which is stock and is a very compulsive gambler and I'd like to exploit that! What can I throw at this C5 to make one Hail Mary run at that hellcat? Cheapest possible scenario? I'm not saying it can be done, I'd just like direction? I know it sounds crazy!!!!

 

Hi Joshua:
1. I'll acknowledge yours is one of the most interesting approaches I've seen for soliciting help! As the other two members pointed out - you need to give someone a chance to help and an interest in helping you. The two who answered also tried to assist you. One asked what goals you had in mind and what you budget was. Very reasonable questions and taking the time to include them in your request for help - instead of your diatribe - would have allowed some of our very talented members to offer insight. The other member provided some useful insight based upon your initial question - however, the good information they provided may not give you all the horsepower you want, since you have identified you don't really want to "wake this girl up a bit", you want to wake up this girl a whole lot and race against your boss's 707hp Hellcat and do so for the purpose of exploiting his being a compulsive gambler. Interesting.
2. You need to decide whether you are going to put your efforts into your LS1 or into the LS3 you mentioned. You also didn't identify how you were going to race your boss - 1/8 mile; 1/4 mile; 1/2 mile; road course or???
Since "budget isn't the concern", I'd suggest you go to a few of our vendors who do engine development and outline your plans. With your A4, I believe you're going to need an engine at least in the 475-525+rwhp range. You can do this with heads, cam, intake, and exhaust but you will have to have a well thought out plan. You’ll also need a performance torque converter that will allow you to quickly get to the optimal hp range, and dependent upon the type of racing you have planned you may want to change your differential ring and pinion ratio and perhaps even build up your transmission and get stronger axles. Also, several of our vendors sell (and can install) supercharger kits which can get you to or above the horsepower mark needed. So, lots of different options there for you. As the old adage used to say "speed costs money - how fast do you want to go."
3. Additionally, if you’re not experienced with the type of racing you want to do to win against your boss, you’ll need to allow some time (and money) to refining those skills.
4. Welcome to the Forum.

 

3.6 and 11.7 is what I found for straight ahead, that's not a boat load quicker than a stock C5Z. The Challenger is a very heavy car.
Throw a blower on your car and make sure you get traction, and I'm guessing you're there.
Racing for pinks?

 

How stock is it?

 

Do a full tune up :

-fluids
-wires
-spark plugs
-shifter
-tires

Then fix ALL existing problems.

AFTER ALL THAT, make a budget, and re ask your question.

most will say Long tubes, intake and a tune.

Make a choice, then make another choice if your not happy or she doesn't get wet...

 

Thank you for your help. I'm aware I may of been harsh n may have kept certain people from contributing and I'm ok with that. I got great feedback. I truly believe that the ones who did respond are the good hearted people on this forum and you guys can't deny what's right and wrong on how people respond to others. I wanted genuine help and I got it, I just wanted to weed the bs out and it worked. In my eyes I wasn't whining or crying, just putting up my boundaries as your guys reply was stating yours. Route99 thank you, and we can debate about other stuff in the future!! Lol Thank you again

 

No pinks! I don't want a Dodge lol. My boss owns a trucking company and is so arrogant, ok I get it, from nothing to millionaire, when he's wrong he's right n when I'm right I'm wrong!!! He has 900hp Shelby both hellcat 2 Raptors, he has every toy imaginable, as I would too with his money! I wanna be his peasant employee who makes his pocket change n wipe the floor with hellcat. Lol I sound crazy, but we've all had a boss who gets under our skin!!

 

Zo6 rims n tires.. STOCK! LOL

 

Exactly what I was thinking, used lsa unit n supporting mods. No pinks, greenbacks! Gotta fund the hp addiction somehow!? Thank you very much!!

 

I'm under the impression lsa SC is a problem cuz of steering rack. Is there a way around it or would you gentleman suggest other SC?

 

A lot of C5's run SC's. The centrifical ones mount along side of engine. Or you could put a 150-200hp shot of NOS to it and hope it holds together! Should be ok for one or two hits.

 

I'm kind of a cheap-*** and so if it were me I'd focus on making what you already have work much better than going through the headaches of swapping in an LS3 for a little bit of improvement (comparatively - unless you're going all the way out and dropping in a built LS3 (such as a stroker) and a killer transmission set up from RPM or RKT).

With that said, I'd probably do something like this:

- Transmission = High stall converter and 3.42 gears
- LS6 Intake or aftermarket
- Long tube headers, x-pipe and catbacks.
- A&A blower

You'd be under $10k with this set up, maybe even much less if you're putting in some gently used parts and doing the wrench work yourself...

Good luck!

 

I couldn't find the year of the car in question. The year would help identify where in the C5 improvement cycle you are, i.e., LS1 or LS6 intake. MY 2000 had a better cam, etc.

 

390 or 410 rear gear .. Been there done it wow the improvement and does not need to be retuned .. Best bang for the buck.. My 2 cents..

 

it's a 01 ls6 intake
