I currently have the tr224/224 .561/.561 112LSA cam in my 00 Z28. I have run a best of 12.48 @ 111 mph w/ 1.68 60ft. Car weighed 3600lbs w/me.The car is a six speed and i have problems shifting from 3rd to 4th so i know my car has a 12.2 in it at least. Anyways i am wanting to step up to a bigger cam and stay with the stock heads for now. Is it possible to go 10's @ 126 or so just by changing to the trex or juggernaut cam w/ tuning???? Because that is more than a second gain w/ just a cam.... Please give me input and suggestions on what i should do. i will also be going with a 90/90 setup and a raceweight of around 3300lbs with me in it>>>
I would like to compete for fastest stock headed cam only M6..
and i have a NX wet kit i will be using as well.

THANKS

Since you want to stay with stock heads the Trex will probably be your best choice. With weight reduction, good tires, great driving you should meet your goals.

What times do you run 2muchricemakesmesick and dyno #'s through the 9"

Thanks

What about P/V clearance with the trex

No. You will not gain 15 MPH, essentially 150 HP, by changing cams and having it tuned. Holding alll thins the same.

Start searching info on here and in the drag racing section. You'll get more info that way. Also, most of the info required to get you where you want is all on this board, you just have to search for it.

It'll save you time in the long run b/c you won't have to wait for answers to the numerous questions you're going to have.

I will be doing around 300lbs weight reduction i dont drive the car but maybe 20 times a year. 45K miles.

And i dont see what these other guys in the 10's have that i dont have other than a big *** cam and tuning......

Please help i want low 11's to high 10's..... then spray a 150 shot...

BTW i want to upgrade rod bolts... Can i do this with the motor in the car if so how.... Thanks

That's fine but you specifically asked:

The answer to that, is no.

Usually you get 0.10 ET reduction per 100 lbs removed from the car, it's a general rule of thumb, not an exact for each and every car/setup.

So, with that, assume you drop 0.30 seconds from your current E.T. You still have a long long way to go, more than just a cam and tuning can provide.


You should already be in the high 11s on a good track and good driving. I know others with smaller cams, stock heads, and much less mods on their MN6 LS1s running high 11s.

This has been thoroughly answered by Jason 99 T/A in at least two separate threads in this forum of the board. Just search and you'll find the info.

Basically, you can do it, but it's not the idea way to do it. You can search and find out why.

my car is not up to its potential right now.. I have tranny problems and sometimes the clutch sticks when racing. My transmission will not go into 4th gear under full load and is hard to get into other gears at times.. I will be getting the tranny rebuilt and beefed up to handle abuse.. So i know my car has an 11 sec pass in it, but my local track sucks and is at 1800ft w/ 85% + humidity..

i had the car dynoed with the tr224 and LT,, no LS6 w/ stock 10 bolt and it put down 363 hp 358 ft lbs with 105 degree air intake temp. A/F 13.1

Well, lets look at what you have:

SLP longtubes, y-pipe w/ random tech cats, these are just two things that pop out at me right off the bat

The people you refer to in the 10s with the setup you're aiming for use:

• larger diameter long tubes, usually at LEAST 1 3/4, preferably 1 7/8"
• no cats
• Proper suspension setup for racing, Hal shocks, drag springs
• FAST 90/90
• very aggressive tunes
• driver skill
• excellent track prep
• other secrets that they have figured out or learned that they're not inclined to share to stay on top of their game

all of the other cam only cars in the 10's are around 415-440hp.

Im guessing through my 9" i am pushing maybe 365 rwhp w/ LS6 intake..... with a 90/90 setup, and trex or similar cam i think i can put down over 400rwhp through the 9".. at 3300lbs w/ me in it why would i not be close to 10's..

So relativaly if i was to get a trex and 90/90 setup w/ racetronix fuel system and have raging motorsports dyno tune my car.. what am i looking at et wise

thanks

3200-3300lbs

You should be close. I never said that you wouldn't be with those specifics b/c this is the first time you have clarified your question with these specifics.

I said that you could NOT run 10s by simply changing a cam and tuning holding all else the same, which is what you asked as I quoted above.

Scalpel

iTrader: (4)

It depends on what your final power output is.

It's impossible to predict E.T. One can make and educated guess but impossible to really say. There are too many variables.

If you can put down the same power with your setup as those that are running 10s then you know that if you satisfy the NUMEROUS other variables that they have that you could then run those times.

thanks alot for the info i really appreciate it.....
i am going to do everything i can.....

will the trex fit without flycutting the pistons????

only thing i have left is deciding what cam to get... it is always the hardest decision..
any help from anyone would be appreciated...

I will be running Nitrous as well.....

Scalpel

iTrader: (4)

Yes, on stock heads that is. That's searchable info.

2MuchRiceMakesMeSick

Yes it fits but its fairly close

Smoken01TA and 01-Z make those power #'s on big slicks and big gear rear ends. Also 01-Z does not have the Fast stuff his intake has never been taken off the car. The Juggernaut cam LOVES N20.

so would i be better with the juggernaut... because it loves nitrous.... has more p/v clearance i think he said 75 thousanths, compared to trex not much.... and he is making good numbers with the ls6 stock intake....

Just wanna make the best decision.... i want the car to run good on motor and extremely good on the bottle...

2MuchRiceMakesMeSick

It is my opinion that ANY cam/motor loves nitrous. I have never seen one that did not respond to it.


One major draw back of the juggernaut cam is you dont know the specs. That puts a damper on when you decided to buy heads.
