I have a wager with someone that the first time out @ the track with their new setup won't produce a 10 sec slip.... did I bite off more than I could chew? The mods as well as RWHP numbers are listed below:



429 c.i. stroker (10.3:1 compression)
24x/24x cam
"well ported LQ9's"
90/90
STS twins (can't remember size)
1 7/8" kooks
Spec 5 clutch

RWHP: 590 ish @ 6.6lbs
this may sound like a silly question- but I don't know how "finicky" FI is (or if it is at all) If this was a bottlefed car I can assure you i wouldn't be asking this question (i'd already know I bit off more than I could chew LOL)... Does it take a long time to get used to an FI setup: or should this car run 10's first time out?

Almost forgot this in a 01 Z06.

Thank you guys for the input.

 

If he can drive, , he should be able to get a ZO into the 10's. Is there a graph that goes along with that so called rwhp?

Dam, with that block, cam, and 'well ported heads' I would have thought he would have been close to those numbers he put down with the boost. High compression plus boost does not work well though, huh? What did the combo run before the 'twins' were added, or was it a 'road race' car?

 

I think it will be tough to do just because it is the first time out in the car. There are always bugs to work out, suspension to dial in, ect. I would say 10's won't be seen the first time out.

 

No, it doesn't matter how much power you have, you have to be able to drive to get into the 10s

 

B is a d-nozzle......he wont hit 10's because he will miss several shifts based on the fact his fingers will be oily from all the cheese *****, in addition he runs the risk of crashing because he will undoubtabley be looking at himself in the rear-view while driving....

 

Sorry but I have no use for a twin turbo dyno graph- as that isn't the route that I went for my own project.... I do however have a graph of his n/a numbers: ONLY because I was doing research for my setup (400+ cubes), N/A it put down less than 500...... exact numbers aren't really necessary (IMO)

I do agree that high compression and Boost don't mix... not to mention a 4.135 bore I don't know when he's gonna get the car to the track (as the car just got finished yesterday)......... but im seriously considering "throwing in the towel" before he gets the chance to prove me wrong.

(the bet is only dinner at the winners favorite restaurant)

 

If it didn't run 10's the first time out I would sell it. You can go 10's alot easier and cheaper than that. I dont think he will have any problems.

 

That's really low power for that setup..

I'd expect those numbers from a stock LS2 with a procharger.

 

racegas and a manual boost controller (say ~ 10psi) for added insurance, some 116 octane would ensure no detonation with a moderate boost increace imho. that could take the driver error out of the equasion and guarantee 10's with a sub-par launch and shifting.

 

That's plenty of power in a zo6 to run 10's. I'd be more concerned with what tire's are on the car.If he does hook what clutch is in the car ? How good of a driver is he? It's not that easy to shift into the 10's.

 

As long as he has a good clutch, suspension dialed in and good tires 10s shouldn't be a problem. It should be making more power than that in my opinion. Was this tuned? Any boost leaks?

 

ditch the twins and go to a dual stage spray setup...but all in all he should be well in the tens with a good 60'

 

So what happened?? Did he go to the track?

 

No, he's still waiting for the driver's mod coming in the mail.

 

OH Man That is just wrong You guys are Harsh.

 

1) The car was only picked up to road test it before the boost is turned up.
The car is totally street drivable and gets excellent mileage.
Quality Assurance and Optimising is being done now for STS & Synergy.
So NO, these are not the final numbers.

It has a completely new drivetrain built handle a 1,000 rwhp..
new fuel system, 95's, two Bosch 420l's, BG filters, Regulator, Return, hoobs switch, etc..
AEM computer
Meth System
STS computer
Different cam
Custom PVC setup
and about a dozen other things.

WE ARE MAKING SURE THEY ALL WORK. So far they are.
This way when Synergy installs them for next ten customers everything will be optimized.

Only one thing is being adjusted on the car shortly to maximize performance.
Boost will be turned up mid-next month.

2) N/Athe car made 500/500 (there were a number of dyno sheets).
When we had more valve lift 520/520 only on 10.3 to 1 vs the typical 12:1 with only a .575/.578 232/236 114 cam thru the cats.

3) At 6.6 PSI it makes 593/583 WITH TUNING AT THE TOP NOT DONE.
In addition at that PSI the turbo's are over 10% out their efficiency range.
You do the math when the boost is turned up, times 110%.
Again thru the cats. No, I am not drag racing at this boost level, so the original question is pointless.

4) As for the compression. It is benefit with

a) proper cooling. This car runs between 175-192 no matter what.
Look at the Saleen twin turbo S7. 11:1 compression. 750-1,000 hp.

b) excellent tuning.
The car is smoother than stock.
Rick at Synergy has done an excellent job here.

c) My intercooler is always at 80-85 vs. 140-210.

As far as track times.
You can only get into the 10's on full interior Z06 with drag tires.
It requires 430 rwhp minimum to get into the tens. EG. Rob Z.
507rwhp/430 torque on a 346 has made 10.5 at 130. EG. Brent EB.

Without drag tires, 11 flat is possible, less probably not. In fact, I have never seen it done. Trap speeds of 135-144 are also possible with NON drag tires, but sticky street tires PS2's and you will be all over the track. EG. An 1100 HP C6 just ran 11.2 on street tireets, but at 144 mph.

Drag tires is completely another story.

The fastest I have run with THIS car is 11.33 at 125 is in December 2002 on F1 street tires with a MTI head and cam package.

I have two sets of STREET tires now, 12.0 track width rears and 12.3 track width rears. (track width being the actual width on the tire from outside of the contact patch to the inside).

Car weighs 3,100 lbs..

I have a very good idea what the car will make powerwise when the boost is turned up as I am in contact with the other owners of this same setup on 402-427's. The first one I called to within ten hp. of his 809.2/796.5 at 12.6 psi. on a 402, no meth, pump gas and cats...

On a side note one my other friends (Not Jeff) is testing a Kenne Bell on his 402. This also a road race car. He has to go through the same speculative b.s.. at 21st CM. It is beyond annoying to the point where WE WILL HAVE IT RECTIFIED IN THE MOST DIRECT WAY POSSIBLE. Wait until you see the final results from the source, not speculative conjecture. I will post the results and my opnions, mid next month. I have done many race logs, this is no different.

 

Cool, well good luck!

Oh btw ET streets are "kind of" street tires, and you can go very fast on those.. 10's are not a problem with ET streets, or a nice set of drag radials.

 

Brent, all that blah de blah blah, just man up and show me some 20psi action. I want to see that thing break the dyno when Rick turns it up.

 

Its harder than you think... I have a mid ten second car (previous owner), but I ran it to a best of 11.4 (I suck at the whole straight line thing).

Brent-

You can borrow my ETStreets if you want a tire to get you the ETs to go with your trap speeds. That way you have no excuses.

Also, I have very similar numbers to you with your current boost. Care for a friendly run or two to see how the boost compares to the sauce?

 

My money is on the black one .....................

the black on the jug that is!
