I know, someone is going to say that you can't have too much power

And if I had an unlimited budget I would agree. However I don't, so I'm trying to push the HP but yet not break the car (or my bank account).

I'm sure somebody has probably asked this before. But I've searched and can't find anything - maybe not using the 'right' search words.

I have a base 07 mn6. I plan on putting on mild suspension upgrades, better brake pads, wide body rear quarters to get more meat planted, and a SC - rated at between 550 - 599 HP (at the flywheel, depending on which onet I go with). The SC will also come with bigger injectors, CAI, etc. so I think the engine is taken care of. I plan to track the car once or twice a year, and the occasional WOT just for fun. My question is if this is a 'good' fit for the stock tranny, gearing and clutch? Or would it be smart to upgrade any of these also? Do I need to upgrade the motor and transmission mounts? It looks like I will have the entire torn apart for this project, so if I need something more it would be easiest to do it while it's apart. I appreciate any input from experienced members!

 

Not a good idea to do it and not a good idea to post about doing it.

 

C'mon, out of his entire post, that's what you choose to comment on? I'm aware of the "no street racing" rules but that's barely a reference to an illegal action. Poor fella's looking for help.


OP. It sounds like you're looking at the Edelbrock SC? From what I have read, it's a good kit but I would check out the A&A/ECS centri S/C kits. I've seen both run and I'd lean more towards them, but that's opinion based and would depend on your goals.

If you keep the boost mild (6-8lbs) and your tune is good, you shouldn't have any problems running your stock internals LS2 for quite some time. The trans and clutch seem to hold up well too for the occasional drag day or highway bursts. The rear will depend on your tires and launch ability. We've all seen and read about rears cracking at the track from wheel hop. If it's bad enough, it can take out your tranny as well. Honestly, how much you should upgrade is going to depend on your budget and goals. If you're looking at a powerful street car with maybe a few drag trips a year, you should be fine with just throwing the blower on and getting a good tune. You should be able to get 550-600rwhp. If you want more, you could install a meth kit and up the boost. If you're going to be tracking it a lot, and have the funds, you could upgrade everything. If you want to upgrade just the bare minimum just to be proactive in possible repairs, I would upgrade the rear diff and the clutch. Trans and motor should hold up fine.

For even more info, check out the FI section. You'll see many cars with nothing more than a S/C, headers, and tune running for tens-of-thousands of miles without major problems. They can offer a lot of useful info.

 

He's a new member and may not be aware of the rules against posting about street racing. I was trying to do him a favor to let him know about the regulation without being bossy about it.

Maybe you haven't been here long enough either to know the rules or recognize when someone's trying to be helpful.

 

I used to say never too much power , my ZR1 is 750. Right now, this time of year, I have trouble accelerating quickly as the temps are cool and the roads cold, this thing spins at will even in 3rd at half throttle, so if I am in a hurry I have to feather it, then try and get on it, it spins, get off it, back on it easier and so on and so forth. DO I wish I had only 638 hp? NO.

 

Racer wins the prize for avatar of the year!

 

^^^I second that!!!^^^

 

It all depends on how you drive. I'm still on the stock drivetrain at 735rwhp but do need a clutch. I've also done many wot runs giving many a ford or import a reality check

 

Sorry, JimTN - I was not aware of the rule and I have edited my post.

I appreciate the input Shado.

Racer - did you hi-jack my thread???

 

550 or 599 HP at the flywheel is a good selection for car used primarily on the street. If you're going to have it torn apart, I would recommend a ZR1 LS9x clutch mated with a Katech aluminum flywheel(Katech offers a complete package). Might save having to tear into it later because you roasted the clutch.

 

Im gonna get flamed out for this im pretty sure, but I got seriously bored with 915rwhp in less then a week... Daily driven.. 60 miles each way to work.

 

Yes....he always has good ones...today is very nice



Now back to topic.

The car is only going to be as stupid as you want to make it. I've driven 700, 800, 1000 RWHP cars here at the shop. I think the overall combo and how the car makes the power is going to make up more of how 'fun' or easy it is to drive. I've been in 400 rwhp cars that I couldn't wait to get out of, and 750 rwhp cars I don't have a problem driving to the store every day in stop and go traffic.

As far as putting the power to the ground...well a 700 rwhp car is going to hard if you try to leave WOT every light, but again if it is a good setup most can be very easy to drive...again depends on the setup.

I can tell you this, the last few 750 rwhp ZR1's we have done here at the shop I would not have a problem daily driving at all.

 

I'm not going to sidetrack the thread but you're original post didn't make him aware of anything nor did it offer any help to either his question or inform him of forum violations. Your next post did however, and your point is now made. As for myself, I am well aware of the rules. Besides, my response to you wasn't in a derogatory nature, hence the flag/salute smiley.

Let's move on for the OP's sake.

 

To much HP is just about enough.

 

To much HP is just about enough. Same for sexx

 

For street use these cars come with to much power if you really stop and think about what is needed.

I would love more power but not sure where I would use it without heading to jail. This is where common sense comes into play. No the limitations of said actions. I can get enough trouble with a stock LS3 in a hurry.

Power wise to trans and diff I would feel safe at 500 rwhp and driven the way I do. ( never put down rubber in the C6 ) Can't help but to think it is a Chevy and do not want to break something. I even got a stage 2 DTE diff. because I did not trust the stock set up, even with my even tempered driving.

 

Power delivery and whether it's a DD or not and the area you live will play a big part. What cars have you driven? A Z06? Any Supercharged Vettes? After a few supercharged and turbo cars I'm going NA on mine. Hopefully a bit over 500 rwhp on my LS2. I'm also doing a nitrous kit although I doubt I'll ever use it.

 

Had a few Nitrous kits, had one on my Z06, S/C or turbo for the street is waay better. Nitrous, you have to make sure the bottle warmer is on, is it armed, do I need to go full throttle??? S/C or Turbo, you are ready for ANYTHING at ANYTIME. At the dedicated drag strip, I like my Nitrous, until I reached the semi's once and my pressure was not up and car ran waay off the dial in. Pros and cons to everything.

 

The answer to your question is very driver dependant on the answer, so it's tough to give a general answer. I have had some customers think their Corvette is "too fast" stock, and others that want more at 1000rwhp.
Along with how well the car is set up matters greatly too, tire used etc.

Actually these days a supercharger might be necessary to fend off that Boss 302 you may run across.
