I was wondering if anyone has raced a Z06 Vette and won or even just kept up? If so, what mods. Please no nitrous or forced induction. I want to know how serious of a motor it takes.

 

Well I know you said no power adders.... But, We have a big street racing festival once a year (3am, desserted road). And there was a new Z06 with ported and polished heads and aftermarket exhaust. The only loss all night was to a 1987 Grand National (Running around 24 psi).

So yes they are fast.

Later, Garrett

 

they are very fast when compared to a stock l98....

i haven't had any problems with stock ones....modified with a power adder they give a great run! with higher compression even a power adder wouldn't help them within reason.

 

I've tried my friends Z06, but im using F/I on a stock L98. Comming out of a turn (onramp) I was able to hang with him to 60, supprisingly he did not pull away like I expected. But on the rolling 60 (even start on the freeway) he pulled away from me, 1.5 car by 100 mph, then shutdown. I think my downfall is the stock tranny and gearing. But anyway, yes those Z06's are fast. I love riding in his car. 4th gear tops out around 135mph. Its a blast.

 

Stock and with a couple minor mods, they can't keep up with the little 306, but today's technology is just so amazing that it doesn't take much before my little motor on wheels doesn't have anything for them.

 

I've beaten both Z06's and Vipers. But my car came with a power adder stock But its still just a V6

Rob

 

Cool stories guys, but I'm still looking for an all motor victory.

 

Mine was all motor (a little one at that)

It just takes too much motor work on these older cars to be able to compete with the newer technology n/a. I really want to step up to a new LS1 or 4.6

 

i agree... yes its been fun pushing my stock L98 as far as it could go, but i would have to dump a ton of money and time into my car just to EQUAL the mph of a stock LS1 Vette

because of this ive been seriously looking at 99/00 C5 hardtops. theres just more potential in these newer cars

 

Nice ET 89vettetpi, I saw a guy with a stone stock 89 vette (except for rims and system) run 15.4 at my track which is about 14.3 at sea level. He was an automatic too. How in the world did you run 13.1 stock? I smoke stock L98's like my friend smokes cigarettes, one right after the other.

 

Ha, yea...notice my sig. I'm unloading everything I own to buy either a 99+ GT or an LS1 TA. It'd just be really nice to have something in the 11's that I can actually drive on a regular basis instead of like once a week, you know?

 

ZO6's aitn ****

 

thanks, GASGZLR! my combo is as follows:

Bought Mods:
- K&N air filter
- Hypertech airfoil
- Holley AFPR
- Exotic Muscle front ypipe
- Borla rear ypipe
- BFGoodrich drag radials
- S10 stall converter

Free Mods:
- cut filter lid
- descreened MAF
- ported plenum
- 160* stat
- removed "frisbee" (Vette mod only)
- gutted cat
- bumped timing
- removed mufflers (running straight pipes)
- bypassed TB coolant

everything else on the car is 100% stock: heads, cam, runners, base manifold, valvetrain, trans, gears, it even has the factory exhaust manifolds! ive recently ported the plenum a bit further and installed a crank pulley. with the cooler weather i am looking for the magic 12.99 out of the stock motor

 

stick with it! C4's are sexy

 

right now im looking to possibly sell my car or take a loan and go after this nice *** 99' ram air T/A LS1 that is for sale by my house....the only thing holding me back is the $$$.


.......not that i would ever want to trade my 3rd gen!....they are all gorgeous!

 

Is it even possible to get a 99+ GT into the 11's without a power adder?

 

Nic has a 306 now,, if its so small why would you go even smaller??? a 4.6 is even smaller.

Post this thread again in a month, and Ill have some z06 destruction stories forya.



IROCZMAN380

 

Fastest I've seen has gone 12.2x on motor. Not many people build these things up n/a because they respond so well to forced induction.

Because the 4.6 is superior to the 5.0 in every which way possible. Well, that, and after seeing first hand the results of what a Kenne Bell'd 99+ GT can do, I've got to have one. example: http://www.kennebell.net/supercharge.../gt96-03_2.htm

 

Had a guy run with us going 12.5s all day in a newer GT! Exhaust, gears, tires, and small bolt ons! very impressive car. Not mid 11s but still mid 12s with ease.

 

Hmm, I've seen a few have trouble breaking mid 13's with those mods, let alone mid 12's. Oh well.

 

If you like, I could get you in contact with him.

 

My 302 put 311 to the wheels last time on the dyno, and my race weight is somewhere shy of 3200lbs. There's a guy with a 2001 Z06 that has ram-air at my school. I'd like to race him, but don't know if I've got enough, especially from a roll. What do you think? What is your raceweight and rwhp?

Chris

 

Depending on how much torque you car is putting down it could be close. However those things are very fast. It should be a close race but I think he has you. 311 horsepower at what rpm???
z06's are putting down 330 rwhp right out of the box, with about the same torque. A good driver can put those cars into the mid 12's. Like I said it should be a descent race ,, do you think your car can do 0-60 in 4.5 seconds or less?? thats what there doing. Just get him to race with some trash talk, and tell us what happens.


IROCZMAN380

 

0-60 is probably less than 4 seconds for me, if I had to guess. The Drag Radials, 4.10s, and 200 lbs less race weight add up to a pretty nice advantage from a launch. I'd like to be able to handle him from a roll, though.

Nic, I don't see how you can say that the 2v 4.6 has any advantages over a 5.0L. Their parts cost more, they are harder to work on, they have less potential (absolutely for N/A, and even arguably with FI). The only slight benefit is that the 4.6 block can take a little more than the factory 302.

I also don't buy the supercharger makes more power for the same cost argument. I know 11s from a streetable n/a 302 can be accomplished for less than the 4,000 dollar asking price of a KB for a 4.6. If they slap on an intercooler, you could slap on nitrous for the same cost and still out run them with the fox. Plus, 14psi is not the most reliable "daily driver" for a 4.6 on stock internals.

The DOHC 4.6 has a great deal more potential with FI, but not the 2v. I think you'll be disappointed if you're really going to go from a 5.0 to a 4.6GT hoping for more performance.

Just me...

Chris

 

I took a Z06 at the track this weekend. I ran a 12.5X @ 110. It was an 01 though.

 

Bolt ons as in cam and heads? Newer GT's are not LS1's.

 

I took a Z06 by 3 or so cars in a red-light race to ~120. Mods are in sig..

 

1bad91Z, what are your trap speeds?

Unknown, what did it trap?

Thanks,

Chris

 

Sounds like the vortec headed, 350 powered thirdgens are representing .

 

I think it trapped 106'ish. I think in 01 they only had 385 horsepower or something like that.

 

It was a street race (from red light stop to ~120). And, it was an '02 with the 405hp badges on it.

 

Someone didn't know how to drive. My 2000 Z28 trapped 106 stock and that was with an auto. A 2001 Z06 should be trapping 110+ atleast. And 25thmustang, you will lose to the z06. Don't even try it from a roll.

Edit: meant to put 12smustang, sorry 25th.

 

I admit he was a bad driver, but a poorly driven car will still mph if the horsepower is there. Altitude corrected for my track I run right around 112 mph so that would put him around the 108/109 mark.

 

Something still isnt right. Those are LS1 vette #'s. A 2001 LS6 should be trapping ATLEAST, I say ATLEAST 110 mph. The 2002 and up Z06's have been known to trap over 115 mph bone stock. Driver does play a big role though.

 

I'm not going to argue with you because I agree with what you are saying. However, had this been a street race it would not even have been close. The point is, the Z06 saw thirdgen taillights the entire way down the track, and even from the 1/8th to the end of the track he never pulled mph or ET on me.

 

Bullit Intake, Timing adjuster, pulleys, Long Tubes, off road X-pipe, dumps, aluminum flywheel and driveshaft, struts, shocks, springs, 4.30s, axles, and at 3400+ lbs he went 12.5x @ 106.x with a 1.6 60' (I believe 1.6) on Slicks! Not an LS1 as one with those mods would be 11s, but still fast!

 

You may be right, but what will they trap? From what I understand trap speeds are usually indicative of performance from a roll. I should trap from 113-115mph, but probably more on the 113 side...

Chris

 

Nice time. If I 60 footed that well I would be in the 11's . Sounds like I need to step up and invest in some ET streets and a 3500 converter...

 

So the 2001s only trap 110 or so, but with 20 extra HP and a few less lbs the 2002+s trap 115? Something doesn't add up.

Chris

 

Here's a car and driver page on it. http://corvette.caranddriver.com/arc...?articleid=127
All I can say is that nobody who cares about their corvette could drive it stock to those times, and I would like to see the 60 foot times of those vettes. I bet that track was prepped the same as for top fuel dragsters to achieve those times .

 

I said 110+, plus meaning more than 110 mph. In that article that Z06 trapped 116 mph, but it was a 2002. They also could have gone even faster, but they didn't want to abuse the car. They are 11 second cars easily will just tires. That, my friend, is amazing. No 2003 cobra can come close to those times with just tires, it takes a little more for them to get to the level of a z06.

 

I saw 2 2004 SVT cobras run 13.7 my track. The Z06 there was doing 13.5 stone stock,no aftermarket tires. We are at 5600 feet.

 

If 113 is about right for a 2001, then I should race this guy. I don't know who'd pull it, but I'd bet his aerodynamics will give him the edge the longer we race. Good night is all I can say to the numbers they got out of the newer one. Crap that thing is bad to the bone! 116mph? Time to go install some nitrous.

I'll try to get this guy to race. I'll let you know how it goes,

Chris

 

So you're probably trapping somewhere in the 108 - 110 mph range? That's not enough to outrun a stock Z06 from a roll, but you may stand a pretty good chance out the hole on a stick tire. I haven't dyno'd my 306, but it's a very radical combination and definitely not streetable anymore...11.0:1, .550" lift cam with a loooong duration and very tight lobe seperation...we're looking at over 400 hp at the crank with this motor with a 2900 lb raceweight...enough to put it deep into the 11's.


Let's see....they're faster right out of the box, they're faster with minor bolt-ons, they rev smoother, and I'd much rather work on an OHC car with OBD II...I do it all day everyday at work. The 5.0's don't start outrunning these cars until you start swapping out to aftermarket h/c/i and then you're no longer dealing with stock drivability. Meanwhile, the guy with the 4.6 GT over there is running within a couple tenths and still hasn't lifted a valve cover and aftermarket h/c/i are just now starting to hit the street.

If you think you can build an 11 sec. n/a 5.0 Mustang with all new parts and keep it streetable for $4,000 go right ahead and then bring me the reciepts when you're done. You'll wind up putting that much into just your motor and exhaust. I've been there and I know what it takes to put one of these things into the 11's on motor, and believe me, it isn't as cheap as you think and when you're done, you're still left with a car that sucks to drive on the street on a regular basis. When it comes to s/c vs. s/c, you're still looking at the same problem...to make as much power with the 5.0, you're going to have to swap to aftermarket h/c/i on top of the blower whereas with the 4.6, 9 psi intercooled will get you 400 rwhp on an otherwise stock motor and 14 psi will put you close to the 500 rwhp mark. You're right on one point though...14 psi is too much for a reliable daily driver with these motors.

I guess we'll find out. One thing I don't have any doubts about is that I'll run just as fast with the s/c'd 4.6 as I did with the built 306.

My .02 based on the research I've done.

 

I think he is easily over 110 with that power. My dad put down 281 rwhp, and at 3100 he trapped 110+. The majority of cars running with us at the last event trapped 108-110 at 3300 lbs with well under 300 rwhp! I think he has 113 in the car with the right gear, tire and suspension!

But the Z06 will pull you after that with ease, because they pull 113 on street rubber, whereas you will most likely be on ET Streets or Slicks!

 

Hey mustang doods,, I guess you are going to come in handy,,,

heres the question: I know this is off the topic but heres the deal:

Im up at shore tire today with a friend, and these two guys with 5.0 mustangs come rolling up. Both 80's style. I know both of them. One of them has a 14 second stang,, while the other has a N/A 5.0 with a 306. He claims that his car runs 11.7-11.8s on all motor, and 10s with nitrous?? Now keep in mind, I know this kid, hes running a stock bottom end,, as far as I know with N/a and this car is 100 percent streetable. I see him driving it all the time. Well he says that he will race me for 100 bucks or more, when I get finished with my 383. I just want to know,, Is this possible??? What am I dealing with here?? How could a car that runs 11's be that streetable.?? Iam trying hard enouph to run low 12's high 11's N/A (streetable) with my 383!!!! thats over 70 cubes I have on him. Well I think hes ing all over the place. CAuse I know if it was,,,,, then he would have a wild cam that would bearly pull idle. I also found out hes got about 2 grand in his motor.. thats not much really. SO try to make somehting out of this,,, I know its alot of junk but,, I want to know if this is that easy to do with a 306. I knew they were good for 12's but 11s??? that seems like if it were done he wouldnt be able to cruise around in it daily like he does now. Well let me know!!!! thanks


IROCZMAN380

 

No, I will do better than 108-110. With short tube headers, flowmasters with 2 1/4" tubing all the way to the tips, a box stock cobra intake, an underhood filter (instead of a fenderwell peice), 3.55 gears, and untuned I ran 110 mph. Well, it was 109.78 to be exact and that was in TX at the end of march (mid 70s). There's no way the car won't run 113, now. The mods since then include long-tube headers that have cleaned up in the primaries and the collectors, 4.10 gears which will bring me into the powerband more quickly and leave me in the powerband as I go through the traps, a ported lower Cobra, Dynomax superturbos with 2.5" tubing, and a fenderwell intake unit. It's also been on the dyno and picked up considerable power. I've got a Tweecer, too, but I don't know how to use the damned thing, yet.

As for price, I'm talking $4,265 (actually considerably less because I sold some of the parts that came with the car to get the new ones, and some of the parts on the car came with it). So, I'm sorry, but I barely go over the "4,000 dollar claim on my car." Though, I'd bet that I went a rather expensive way with my setup.

1300 - AFR Heads
400 - Cobra intake
250 - porting
200 - bullet MAF
200 - TB
325 - FTI cam
200 - 24 lb injectors
300 - King Cobra clutc h
200 - 4.10 gears and installation
270 - Dynomax STs
390 - BBK long tube headers and H-pipe
230 - 1.6 Roller rockers
70 - Pullies
130 - 255 LPH pump

So, for $4,000 I've got more than just my engine and exhaust. I dynoed only 7 less rwhp than Kyle did with his 11 second 93 Cobra before my 2.5" catback system, before going back to a fenderwell inlet, and with a ****ty tune. His car was heavier, less suitably geared, and had no serpentine belt at the time. So, our cars should run comparably with, I think, a slight edge to mine. I'm sorry I don't have timeslips more recent than my 109.78 trap, but even though I'm bench racing I'm obviosly going to run better than that, now.

FWIW, the reason your car was not streetable was exactly what you hit upon, "11:1, long duration/tight LSA cam." Mine is not a really tight lobe seperation, only runs 10:1 CR, 550 lift, and I'm not really sure what you'd consider long duration. The car idles perfectly stable with a very minimal lope (much less than either the e-cam in my buddies car, or my old comp cam). It's honestly hardly noticeable at idle. It gets at least 20 mpg on the highway, but I haven't managed to go a full tank without putting my right foot down so I think it'll do better. There are only 2 streetability issues, and I do not have a problem with either: The car will not stay at constant speed at less than 1500 rpm without beginning to buck, and the King Cobra clutch is really stiff compared to hydrolic clutches in most cars. I couldn't be happier with it, and wouldn't hesitate to use it as a daily driver if I drove daily, and I dare say neither would you.

I 100 shot of nitrous would be as safe as can be with the stock shortblock, as you no doubt already know, and of course getting to the extreme side of things you can go on up to a 200+ shot and be putting down every bit as much as those 500 rwhp boosted cars. Don't forget the weight advantage you'll be giving up with the SN95s, though. I wouldn't argue against the fact that the factory 302 blocks start having trouble at that end of the spectrum, but with a 100 shot, they certainly don't, and I intend to do as much after I run the 11s that I seek on motor. Not to mention, I'd feel safer with a correctly tuned 200 shot than a twin-screw 14 psi that I can't turn off for daily driving.

Different strokes for different folks though. I'm not sure if you recognize my name, but I've seen your various posts over the years, since well before your car was the beast it has become. I can't help but respect your opinion regardless of agreement as you've already done the 5.0 thing and are moving on to try something else. Good luck with it, but don't discount the numerous remarkably fast, remarkably cheap 5.0s out there. You can go fast with anything it's just a matter of taste... I don't see 4.6 2Vs as superior in any way, but perhaps stock as you already mentioned *cough* 93 Cobra *cough*.

Chris

 

Yes, it's possible, but I'd bet money on you in this race. I don't see how he could do it on 2000 unless he's capable of doing some great porting and finds great deals on used parts. As I said, I'm without a doubt that mine will run 11s and it is very streetable, and it could be done cheaper, but not that much cheaper unless you're Bob Cosby or something.

Then again, he could be lying about the money he's spent on it.

As a matter of fact, if he claims he's got a nitrous kit, but can run 11s n/a and has only spent 2000 dollars nitrous kit included, then he has to be lying about something.

 

I am.
1995 Trans Am
390hp @ the wheels N/A
LT1 Block
LT4 heads flowing 290 cfm
6 spd.
3.73's

Only problem I have is traction (go figure). Being that the Z06 has wider tires than I do, they can get the jump sometimes; from a roll, it's a massacre. Right now I have BBK LCA's, relocation brackets and 275/40/17's.

It's not cutting it. I'll be getting the same wheels in 11 inch soon with 315/30 rubber. Then we'll see some times at the dragstrip.

I've done a few things to the motor since it was dynoed so it's runnin' a bit stronger, nothing major, just a few extra ponies .
I'd estimate my car to be putting out a bit over 460 hp at the crank.

That's what it takes.

 

I think you need a bigger carb to feed that 350 with that big of a cam.
