How much HP to run with a C6?
 

Yes I realize that these types of posts are retarded, but I just saw a REALLY nice Z51 C6 on the way to work today and I'm having a hard time not looking for my next 'toy'.

I'm making 286 RWHP right now. A Vette makes 400hp, so with say a 20% drivetrain loss that would be 320 RWHP.

I have a '95 without the Bose, so not sure how much it weighs. Not sure what a C6 weighs either. Can anyone help me out with this and possibly save me 50k?!

u need about 330rwhp.
the c5 zo6s were 405 hp. An fd needed atleast 350 rwhp to beat one.

if it was a z51 c6 it has 505hp! you need more hp than 350....

O and the C6 z51 does 60 in first! have fun with that....

You're going to need 360-400 rwhp at least to run with them.

I'd actually let you know in about a week. A friend just ran one to a tie from 20 to 100 mph in a modded 465 rwhp E55 AMG Benz. I've got 365 rwhp, so we're going to do a benchmark 20-100 run very soon to see where it stands.

I'm sure a single turbo and supporting mods will do you fine and cost less than 50k. But you're comparing it to a stock Z51 C6. Not sure how it would fair against a modded Z51 C6 though.

Yer mixing up the Z51 package C6 with the Z06 C6.

So 350 RWHP eh? I'm not even close. I swear my Rx-7 feels faster now than my '04 Vette which had 350 HP. I hear those C6's fly though.

I have the full exhaust, downpipe, PFC, intake. How do I go about adding even 30 more HP?

Umm, assuming your reliability mods are done (silicone hoses, boost gauge, etc.) I would add a radiator, intercooler, fuel pump, bigger secondaries, boost controller, and turn up your boost (get it tuned) to 14-15psi.

I've seen a few C6's at the track. They only trap around 108mph. A 320 whp RX7 should take care of that easily.

A watched a new C6 Z06 run tuesday and it ran a whopping 13 second pass 3 times in a row.

bad driving!

108 traps? that isnt very impressive. I know the C5 Z06s trapped a lot higher than that. That C6 Z06 may have ran a 13, but what did it trap? those things are monsters. I'd love to see how my FD will fare against one of those, but havent seen any on the road the few times I have driven my FD lately.....

if your driving is up to par, you will be able to keep up with one at around 300 rwhp, a little more and you should take him fairly easily. They only go like 12.7x with perfect driving... Look out for the Z06 though, you will prolly need closer to 400 to keep up with that.

It trapped between 117 and 120. Trap speeds don't lie....... a 360whp RX7 will take care of that.

The mags got 125 to 127 mph traps out of the Z06s. Ideal conditions, superior driving, strong cars? even so, The new vettes are pretty damn fast. That's not to say I won't enjoy whooping up on them :D

There've been some bone stock C6 Z06's trapping 126-127 around here, and some running 11.1 - 11.2 stock with just BFG drag radials.

a 360 rwhp fd traps 117-120. its not gonna beat a new z06.

A 360 rwhp fd hardily beats the c5 z06. Plenty of stock c5 z06s have trapped 118mph.

I raced a 405 hp C5 Z06 from 20 to 120. With two good drivers, and an even start, he pulled one car length on me. I calculated that I would have needed 310 rwhp to be even with him, just using weight/hp ratios. The new C6 is about the same hp as the old Z06. Therefore, you would need over 310 rwhp to beat a new C6.

Never having dyno'd my car, this race told me that my car has *about* 300 rwhp at 13 psi.

360whp FD would beat THAT car.

Hardly beats a C5 Z06? I've seen C5 Z06's get slaughtered by bolt on RX7's in the 360whp range.

That new Z06 better be fast for 80G.

By hardily, I think he means that it easily beats a c5 z06 at 360 rwhp. That seems right to me.

that doesnt work.....the c5 zo6s trap 115-118rwhp Stock. that means a fd would need around 340 to tie.

a 360 rwhp should beat a zo6....but the poitn i am making is that it would be close. it hink u need abouth 340 rwhp to be equally as fast as a stock z06. 20 rwhp additionally doesnt make it a slaughter. just look at the traps speeds that i keep talking about. that says it all. i dont know how u can argue when the trap speeds are identical.

A stock 02 Z06 has 405 hp. Subtract 15% for drive line loss, and you get 344 rwhp. It weighs 3120. That gives us a 9.07/1 weight to rwhp ratio.

At 2800 lbs, the FD will need 308.7 rwhp to have an even ratio with the Z06. Using these numbers, an FD with 360 rwhp should easily beat a stock Z06.

My car at about 300 rwhp was very close to the Z06. With another 60 rwhp, I would have won by a sizable margin.

Z06 info taken from this site:

hardly... I beat a c5 z06 by a bumper with dp/cb/intake/basemap PFC and nitto drag radials and who knows what he had. we need LESS hp than they do to be equal... not by alot but we dont need anywhere as much Stock c5 zo6's run mid 12s with pro drivers, so the other 80% of the world is gonna run high 12's low 13s.

And with those mods I had around 300whp if that, probably a little less.

c6 z06s are damn fast..thats all i know :)

All I know is I'll be a new owner of an FD by the latest friday and I cant wait to race anything.

How fast does the C-6 get through the corners? I would be cool to compare low and hi speed autocross times. That would be a better test of the overall performance of both cars. Compare them modded and stock.

Everyone that seriously drag races an FD winds up putting in a 9" Ford rear axle and dumping the IRS because the car won't hook. It can't transfer weight because there is not enough to transfer anyway!

In the real world, the FD is my choice. It's like a race car for the street, it feels like one when you drive it, like a big shifter kart.

Both of these cars were bone stock including the tires.


Fastest C6 time 12.48 @ 112.11

Fastest C6 Z06 11.310 @ 127.52


360 rwhp in an RX-7 will easily beat the C6 but not fast enough for the Z06...
You need 410 rwhp I would guess...

Not really, the Z06 C6 has 505Hp, the C6 with the Z51 package is the same HP as the regular C6, just with suspension upgrades.

That's just comparing STOCK Vettes. What happens if he has mods as well?

You got it. The C6 Z06 wasnt made to be a drag monster. Sure its fast as hell in a straight line, but put it on a track and its at home. Shit, its got the second fastest time in all production cars for a lap on the Nurburgring track in germany. Only second to the Carrera GT.

Not that I dont love my FD, it just seems nobody on this site gives other cars the respect they deserve...

we have your math racing vs real world time slips. i dont know what else to say.

A 310 rwhp would get beat by a stock z06 pretty badily. There is no point in debating this. time slips dont lie. there is no better way to determine a cars perfomance than their time slip. math and dynos "can" be bullshit!

so what about the c5 z06. they have been known to run high 11s at 117-118mph. how much rwhp would a fd need to beat on of those?

actually guys i got the chance to take out a brand new z06 last weekend (HOLY FREAKIN BALLS) and honestly, yeah its fast as shit, but its not toooooo too far off from my 7. i would estimate my power probably 300-340 at the most. if we`re talking an ls2 c6 its not even a contest if you ask me. we can hang with that easy with a few simple bolt ons.

i would agree maybe 400-420whp would keep with a z06.



oh heres a pic my buddy took of me when i had it =) oh man i love my 7 but that was something i`ll never forget!

Matty,

In the real world, I raced an 02 C5 Z06. No math, no dyno's. He beat me by 1 car length from 20-120. He consistently barely pulled on me the whole way. My car is not heavily modded (see sig), and is run at 13 psi. There is no way that my car is putting down much over 300 rwhp. No way. Add 60 rwhp to my car, and I would have beaten him badly ............ in the real world ;)

The math is off. The power-train loss is about 7-10% for the C6 Z06. That may be because they low balled the numbers. Also you have over 300lbs of torque from 1500 rpm on.

On street tires 330-350 will take a C6. If the Z06 can hook up you will need much more power With an average driver you can hit 1.6 second 60' times all night long.

I've run one and have between 330-350 rwhp, while I did beat him to 60 it was only because it wouldn't hook up. You pretty much can't give it full throttle until you shift to 2nd.

Also no 350 rwhp rx-7 with street tires is going to crack the 11. You'll need slicks and the suspension set up drag racing. Which I would guess would be detrimental for cornering.

Slicks my ass........

Strap a pair of Mickey Street Radials on a 350whp RX7 and you'll be running consistant 11.50's if you're a decent driver.

I think he was probably refering to any kind of drag specific tire.

I don't want to offend anyone. I am young 20 years old to be precise and I was originally on fully modding to my tastes my FD over the next 4 years.

However, I have a few words for you guys that equal the price of the Corvette, Ultima GTR.

Not without a drag modded suspension. The suspension will snap like a tooth pick or just have poor weight transfer. At near stock levels I have broken several part on hard launches.

Also were is the video of your 603rwhp run?

holy shiet that looks crazy :MissileSm

I raced a c5 zo6 with stage 3 heads and a large cam from a 35 roll and had a car on him by 140,even going from 2nd gear which is not the best.
We went twice and had the same result I,m putting down 340 seq twins w/all the bolt ons.

Anyone who raises the horsepower on their car without upgrading their rear end is silly anyhow, it will break shifting from 1st to 2nd. What's your point again?

so when are you headed to the strip with the monster? :)

Zo6 Car With Heads And Cam Tunned,et Streets And Two Step, Good Driver. 11.01 Best Time! I Ran Slight Moded Zo6 With My Fd Dead Even Till Third And I Pulled One Car Before Traffic Got In Yhe Way. I Was Running 340 Hp. The 505 Hp Corvette Is A Different Story They Pull Hard On The Top End. I Still Dont Want Another Vette,flipped It Upside Down.

They aren't 3300-3500lb boats anymore.
Last I heard the new C6 zo6 is 2700-2800lbs AND 505hp so you need at least 500-520rwhp to keep up!!!!
11.3/127 on stock tires is just sick.

I put down 410-430rwhp and could only trap 11.6/121 with Drag radials on a 2750lb fc

new Z06 = 3130lbs. :D

i like the newer vette and all, but everytime i see one out of the corner of my eye i think its a rx7 for a sec.

anyways, id take my fd over a vette anyday.
crap i paid 9500$ for mine with a new motor and turbos and mods. 40K more to spend to try and "keep up"
thats funny.

anyways, most vette owners ive ran into are old douches. same with s2000s though.
NOT ALL of them, but alot of them i swear have somthing stuck up their rump.

What?


The Z06 weighs 3140 lbs and they make 445-450 rwhp.

Fd's with 360 rwhp can trap 11.4's at 120 plus.

Bostin Fd ran high 10's in the mid 120's with 400 rwhp.

They dyno around 345 rwhp and they weigh ~3145 lbs.

It takes 340 rwhp RX-7 to run with a 390 rwhp modded C5 Z06.
