lol i believe you over paid

 

The problem with your calculation is that you are talking about getting to 400rwhp, however a stock C5Z is not 400rwhp.

 

Holy crap you got shafted. You can get 400+ rwhp cam only + bolt ons for less than $5,000...and that's only if you buy everything brand new. My LG Pros, borla stingers, and honker intake account for $3500 of that so you do the math.

That being said, anything can happen on the street. On a closed course with both bone stock cars on sticky tires, C5Z everytime, even with a worse driver.

 

maybe I did. It was early in my ownership. and also did transmission cooler, oil cooler, accu-sump, AL fly wheel.

I did not do any of the work myself. at that time I paid other ppl to do the work. NOW I could do most of the non internal engine mods myself.

Dont think you get over 400 rwhp with cam only on an LS1 type engine with 241 heads. Close,

look also at what it may costs to reduce the wt of a coupe? Changing seats, was a huge wt reducer. took out close to 100 lbs when I took the both stock seats out and replace with aluminum 10 lb seats. now my seats suck for long drivers on streets.

Oh yah I did have wheels and tires in that too the first year.

any way, back to the OP's topic,

many ppl talk about 'equal drivers". Well that is the ONE thing that may never be equal. Cars may be equal, but drivers seldom are at equal skill levels.

other things to consider:

wt of the coupe / LS1s HP = X

wt of the ZO6 / LS6s HP = Y

if you do not reduce the wt of the coupe, the coupe will need more HP then the Zo6 for X to = Y

and figure in an additional 200 lbs for the driver too.

to make thing easy:

lets say a coupe with driver is 3450 lbs
coupe HP is 350

Z06 with driver is 3350
Z06 HP is 405

so for the HP to wt ratio would be:
coupe 3450 / 350 = 9.86
Z06 3350 / 405 = 8.27

so theoretically for the coupe to be 'equal' that would be

3450 / 8.27 = 417.16 HP

or reducing the wt of the coupe by 100 lbs is a STARTING place. But we all know there are many more factors.

 

I think I shaved off 40-50 pounds with my headers and exhaust. Every 100 lbs is equal to about a tenth in the quarter mile. Every 10 horsepower is equal to about a tenth in the quarter mile. I believe you could get a coupe to run 12.4 with some sticky tires, headers and tune with a good driver.

I made 409 rwhp 405 rwtq with a small cam and 5.3 heads.

 

CLASSIC!

I have $10k in my engine set up and I can tell you that my buddies C5Z with intake, LT's and exhuast is in my rearview mirror every time we race. Even when we switch drivers.

 

411rwhp on stock heads here. Find a stock C5Z that will keep up.

I understand the C5Z is America's supercar but don't underestimate the LS1 fellas!

 

I think it depends on your point of view, are you a road racer or a drag racer. Won't take all that much to match the stock Z06 in a straight line, but on a road race course I believe that it is a different story. You would have to g replace shocks, springs and sway bars plus wheels and tires. You will have to cut the weight by > 100 lbs and you will still not have the chassis stiffness inherent in the fixed roof coupe.

 

on a road course the Z06 will outrun me in the curves but if i'm anywhere near him in the straights, if he's stock i real 'em in and go by them. At the strip it's usually me by a car length or 2 depending on the drivers skills. Mods and power in sig.~Cole~

 

I have a question. How do all you coupe/conv guys stack up to a ZO6 that is modified like your's? I notice it's always stock ZO6 versus mod C5. I'm betting you turn tail and run.

Haha, yeah... Z06s aren't allowed to be modded apparently.

 

Haha, at least we do qualify our statements by stating that we are pitting our cars against a stock Z06. As far as hp, the LS6 has different heads, cam and some higher flow cats. Once you mod a ls1 with heads, cams and headers, the Z06 could do the same and really its the same game. LS6 engine will have no advantages once the modding begins. Z06 will still have gearing advantage but any C5 can easily change gears. Once modding begins, the true advantage of the Z06 is weight and possibly the chassis rigidity.

 

The Z should thrash it. Headers and a tune will not get the LS1 close to 405hp never mind gearing and weight. Above 150mph though look out

 

The C5Z would beat up on that lightly modded C5 pretty good at a 50 roll.

Mod that C5 up like I did mine and it's Z-ya later!!

 

I don't get this. I've got an '01C5 with no engine mods, catback exhaust, B2 Vararam, and 3:90 rear end, and ZO6 swaybars. No other go-fast mods. I haven't dyno'd it since the additions, but I'm pretty sure I'm not anywhere near stock ZO6 power. Here's the rub; when I slap on the racing slicks, install the hardbar, and head off to the track, I'm not getting run over by a stock ZO6 with his slicks on. Now I'm no Lou G by any stretch, but on the track gearing, good suspension and tires can make up alot of HP difference, IMHO.

 

I'd love to race a modded C5Z with the bollas to go against my C5!

 

not surprising. we are talking about a drag race here. put corners in the mix and driver makes a huge difference.....

 

and even against many modded Zs, a modded coupe can do quite well.

Drive skill has more to do with the cars ability then car modifications.

Even with my underpowered 400 rwhp 3250 lbs( with me inside) coupe can do quite nicely against ZR1s and C6Z06s.
I may get my arz smoked on the straights over 125 mph, but out of a corner and up to 125 mph, I hold my own very nicey. However, road course are mostly corners I can corner faster then most ppl can drive on straights

 

Be careful what you wish for

 

Im in.
