[/qb][/QUOTE]Coach is running 11.000 @ 123 with a raceweight of over 3500 lbs And he's an M6 to boot!! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> [/QB][/QUOTE]

That is huge MPH. Raughammer is only going 125 MPH and he is deep into the 10s. M6 makes a huge difference i guess.

11.00 last time I checked isnt 10's?
The point I was trying to make is its alitttle easier to run a number in a car that 400lbs lighter than it was,I think we can all agree?If the coach does it (which I think he will) this will be very impressive to me.But remeber he has a fully B&BP shortblock.Its not a stocker per say,but to run 10's at his weight with a hyd cam will be amazing when it happens..

Dont forget about Dave RUQWKR, he is running somewhere in the low 10.7 @125, with the GM LS6 CNC heads, not sure on the cam. He does have the stock bottom end though. He might of got a 10.6, not too sure. He doesn't get on here alot, but he might jump in.

Hey guys,

Let me say, I have been trying to get into the 10's all year long. As stated above I have gone 11.001 @ 123.61 mph. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> My weight was very close to 3450lbs. The scale at HRP was broken. At the Thunder racing Shootout I went 11.03 at 123.21 at a weight of 3520. <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" /> My motor is a 346 with forged Oliver rods and JE pistons with a HYD 230/224 on 111 lobe Thunder cam. Stage 2 GTP/Thunder heads. Iam a 6 speed. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

I wiil still try and get into the 10's in the next couple of weeks before the Hot Rod goes back to Thunder to Freshen up the motor for next years racing season. The season starts in Feb. at the IHRA NAtional Event at RCR.

My motor has 347 passes on her since April. <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" /> I think that it would be safe to say; I just love to race. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Special Thanks goes out to Thunder Racing for building such a great motor. <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />

Good luck to everyone no matter what shop your from! <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />

Sure Scott but you have a 2200# race weight. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Terry you have alot of weight reduction mods I haven't done yet. A-arms, brakes, & hood to name a few. How can I be lighter than you? I find it just a little funny you are questioning the 10 sec capability of my heads. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Now that I've got the flowbench, look out. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Look me up this spring for a winning set of heads. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Are you ever going to get past my 10.82? Jeez you've had months with 50+ more cubic inches.

I will take bets on whether or not I will hit 10s before the southern shootout in March. No real weight reductions except seat removal and light weight wheels (3480#s). I am heavily relying on good -DA air though. It's going to happen. It would have happened This past Sunday if the track hadn't gone to crap so early. It's a very comfortable daily driver. 10s with the stock bottom end LS1 346is definitely a challenge, but achievable.

MTI Stage II heads
C1 Hammer cam 112 LC
All the normal mods.

Scott I've been to Carlsbad once with the new engine and blew my tranny in the process. I hope to go back this weekend if the new cam is in.

I did take 9-10 1/8th mile passes and have the quickest NA LS1 1/8th mile car on the West Coast (ls1tech.com), as far as I know. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I don't think my tranny's doing so hot either. The last 3 times at the track my first run was the fastest. Even if I let it cool, it seems to slip on the big end.

What are you doing for a tranny now?

Default Re: What cam and heads combo is proven for 10s on stock bottom end LS1s?

I'd be curious to see a different type of shootout. Everyone runs factory wheels and tires and must have a factory weight, i.e. whatever it states on the build sheet. I think this would clearly show how much et is dependant on race setup rather than h/c packages.

Good reading guys and I'm totally shocked how you guys are dropping close to 500lbs more than my current race weight of 3768.

Good luck to everyone. I'm just hoping to run solid 11s on stock wheels (front and rear) and all season tires.

Yes, Guys and Gal, this has been one heck of a thread to say the least. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Give me your opinions how close you think i could run on my current stock cubes/bottom end, with all of the current mods listed below on my 98 A4 C5 with FLP tranny and PT Yank 4000 stall and Getrag 3.73s, if i simply upgraded my 1.5 year old NON-X Package Cartek stage II heads and H cam (222/226, .567 lift, and 113 lope) and instead stepped up to the

MTI Stage II LS6 heads and X1 cam (230/226, .591 lift on a 112lope. How much do you think i could shave off of my 11.6 current ets and how many rwhp and rwtq do you think i would increase to (presently at approx. 380rwhp and 400+rwtq)by simply upgrading to the new MTI radical heads and cam referenced above.

Thanks for all replies here!

Oh but who's running the number with a 1st generation LS1 cam, 224 .535, mild compression 10.6, stock intake valves, and no tuning. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

...and the car hasn't seen sub 1000DA's

Bri,Your not 500lbs lighter than me,Of course I dont weigh 195 either <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I'm really thinking like you are lately,I want a 11.60 car on DR's and maybe a small 75WET shot just for S&G's..

The total race BS is getting boring and to tell u the truth,the I'm better than u crap has given me a bad taste in my mouth.

Good luck w/your car......

JS thanks for the words of encouragement. The 500lbs thing was in reference to people with 3200lb race weights and lower. I have weighed my car at 4 different locations (3 of which were daily calibrated and used for weighing petroleum products on tanker trucks) and I always was between 3750-3770 depending on how much gas was in the tank.

I just can't imagine how to pull out 500lbs from the car, but I guess people can be creative and find ways.

Good luck to all and enjoy your rides.

I think the focus on Cartek has been the fact that they have a H/C package that is in the 10's for a Z06. With a gear their cars are dynoing 450RWHP. With a stock 3.42 it should be around 463. Is anyone close to that with H/C?

Now, my z06 weighs ~3012 lbs without me 3194-3220 with me in it... in it with no mods and minimal fuel.

An F-Body running 11.0's @ 3400-3500 lbs is very impressive to me, maybe more than a Vette doing it that weighs 300lbs less.

So, I think a fair comparison here would be are there any vendors or folks out there in Vettes (especially a Z06) with 6 speeds in the 10's other than Cartek?

I don't think a fair comparison can be made with a A4 car with a big stall and a solid axle that is 60' 1.4's vs a stick car with an m6 and an irs.

I know a few cars...

1 is 3550lbs actrul race weight with driver 6 speed, run 11.1@124

the 2nd is 3450lbs and it runs 11.2@125 also a 6 speed.

I know these are not 10sec cars but if the we go by the weight advatage there are well capable.
