I have an idea what the ol 72 is going to run in the 1320. Im ready for some bench racing now!
Combo....72 Camaro, est. wt is 3350 or 3550 with me on board.
LS3 crate motor with a Bullet Racing custom grind,220-230 at 050
on a 108+4, 629 lift on both sides. GMPP LS3 dual plane, Fast EZ
efi, hedman 1 7/8 long tubes w 2 1/2" dual exhaust w street flow
mufflers.
2004r trans w 2200 lockup converter, 3.42 gears in the 8.5" 10
bolt rear.
3" aluminum driveshaft, billet specialties streetlites 17x9 1/2 rears
w Nitto NTO5R 275-40s.

Other than a set of SSM lift bars, the suspension is set up for handling, not straight line use. This is a trip to the track to set up the timing in the MSD and tweak the fuel trims on the Fast EZ.
I didnt build it for drag racing but I am just wandering what my friends on LS1tech thinks it will do.
My estimate is 12.20 at 115 mph with a 60ft in the 1.8s. How far off am I. The answer will come next Saturday, weather permitting.

12.0 give or take.

Yep low 12s maybe high 11s with good tuning

Well I dont feel alone in my thoughts anymore, LOL. Both of you are on the exact same page Im on. If it breaks into the 11s, the beer is on me! You will just have to come to Ga to get it.
The car flat out humps down the road, but i dont know what its going to do from a dead stop w drag radials at the track. If the converter will let me leave hard, I dont think 11.90s are out of the question. We will see.
Anyone else have a thought?

11.8 @ 114..................ish.

Just wandering about the two step on the MSD box. Will that help me in anyway ET wise? Im sure it would help with consistency, but Im not bracket racing, just tuning the car. looks like the track trip is going to be put off another week. They arent having open track day this Saturday, and I wont go on Friday night. Too many crazy people.

2 step is for use with a trans brake usually. The converter is pretty tight. I'm gonna say 12.30's @ 109-110

newschool72

Thanks for the 2 step response. I sure hope you are wrong on the MPH estimate. Im making a solid 80-90 hp more than my 05 gto and am a good 200-300 lbs lighter and it trapped 109 mph. I will be very disappointed if it doesnt do in the 114-116 mph range. Ive seen 5th gens trap in the 106-107 range , bone stock w the same base engine I started with.
As far as the converter goes, the cam and intake are both built for really good low end torque. But even at that, I still think the 60fts will be weak. I am expecting 1.8s, if it hooks.

Anyway, I guess all the guessing will end pretty soon. I am getting excited about the test.
I wish I wasnt so worried about some yoohoo slamming into my car on the Friday night free for all, or Id go tonight. All the track officials say to stay away on Fridays, if you have a nice street car because it can get out of hand. I saw a guy grab a glass hood and run with it after it blew off an s10 going down the track on a Friday night T and T.

I hope I'm wrong too lol, but I learned long ago to hope for slower and not be disappointed. I picked up 5 tenths changing from a 2400 to a 3200 converter

Yea, Im with ya on the aim low thing. I just see a lot of really impressive #s coming from not so impressive combos and am hopeful my combo will perform well. I videoed a 15ish to 85mph blast a couple weeks ago and it took less than 6 seconds. That was on street tires, rolling into the throttle, slamming the rev limit of 5500rpms in first (before I fixed the rev limiter) and shifting at 5500 in second. It was also with the No5 chip in the box that was pumping an extra 20*. Everything was wrong with the timing curve. The car pulls every bit as hard as my 68 camaro that runs low 11s at 120. I know all that is blah,blah,blah BS that doesnt mean much, but the car is fast for a mild street car. Im just antsy to get to the track and be able to hold full throttle for a few seconds without the "48 yr old ,married, father of 2" brain making me get out of the gas!LOL

IF you go on a Friday TNT....get there early and get out before dark I guess ?

I do like Saturday TNT's too....more $$ but better all around IMO.

Awaitng a driveshaft and I'll be sneaking out too

newschool72

iTrader: (12)

The saturday TNT is very laid back. Mostly older farts like me just tuning on their stuff. It opens at 1 pm and if you get there early you can just go roundy round, if you want to. Half the time there isnt even someone to line up with. Its almost like renting the track.
I was just texting with a friend that knows the guy putting the hard tire event on next weekend. He told me to go meet the guy and tell him that I built the motor in the 3rd gen that spanked him last weekend. I put a 383 together for my friend a couple years ago that is beating up on the hard tire guys lately. He is running 7.0-7.2 at 98 in the 1/8th on dayton full tread street tires on a little spray (100 shot).

Doug G

WOW... lil' different here on a Sat.
Get there as soon as the open and get tech'd in...make a few passes in an hour sometimes.
As the morning rolls on the fast guys start showing up...But a much better group IMO. I made a bunch of hot laps and had to park the car before due to me needing time for a smoke and a soda ...LOL

Did a little road test from 0-80 with the Nittos and new timing curve this morning. It spun first gear, then grabbed hard after it hit second. Pulled to 80 mph really quickly, but didn't film it this time ,so no ET. It felt strong and I didn't hear any knock, so going to go with the curve I have as a base line for the track trip this Saturday. HOLD OFF RAIN!!! LOL

Keeping the nittos on? I have great luck with them on the street but not at the track.

newschool72

iTrader: (12)

I am just going to run them for the track trip. They are the NTO5Rs, not the 555s. Most people Ive asked have had good luck with the NTO5Rs, not so much with the 555s. I run the Mickey DRs on my 68 Camaro and they do really well, IF they are nice and warm. The Nittos were stone cold when I nailed it this morning, so Im hoping with some heat they will bite good enough for my mild stall. We will see come Saturday, I hope. Weather man is calling for typical Ga humidity, mid 80s and a chance for thunder boomers. Id pay 100 bucks for a cool front about right now ,LOL.

I was very impressed with the power straight off the line in my little 0-80 blast yesterday and decided to do a little calculating. I compared my 68 Camaro to the 72. The 68 is running a TH350, 4.10 gears, 27.8" tire with a first gear ratio of 2.52. The 72 is running a 2004R, 3.42 gears, 25.7" tire with a first gear ratio of 2.74. At 5500rpms the difference in MPH is less than 1.... .85 mph to be exact. The 68 stalls at 2600rpms by the tach, the 72 stalls at 2200rpms by the tach. The 72 has a cam and intake much more suited to low end torque than the 68. The best 60ft Ive done in the 68 is 1.62. The more I look at the two cars the more I think ,with traction, the 72 might be a good bit quicker than I have been thinking. Hmmmm?
I bet you all will be glad when I finally make it to the track, so I will shut the He!! up about it, LOL.

Well streetknight 2 wins the beer! This is embarrassing but here it is......12.4 at 109 with a 1.7 60ft on the first pass. That was the best one of three. The 60 fts were the only bright spot in the trip. 1.7 was better than I thought it would do with my stiff suspension and street gearing.
The bad part is something is killing me on the upper RPMs. The motor is all in at 5500 rpms! I pushed it to 6k, but it just slowed down. I have narrowed it down to 3 possible things
1. The tight LSA on my short duration cam is done at 5500
2. I have a spectra cold air kit, but have the low profile bonnet on it because of hood clearance. I wanted to remove it at the track to test the theory , but would have had to let the cone filter dangle behind the headlight and was afraid it would have fallen out and hurt someone.
3. Ive had an issue with the rear disc brakes dragging when they get hot. They started screeching after my first burnout. So they may be dragging. I think that may have had something to do with MPH at the big end, but cant see that limiting my rpm.
Anyone have any stats on the effects of a low profile bonnet?

ZONES89RS

iTrader: (25)

That cam should be pulling to 6500. You have issues somewhere that need to be figured out. Should have run without a air cleaner. You dont have a wide band?

newschool72

iTrader: (12)

Yea Zone, I should have popped the bonnet off the cold air kit and tried it. I just didn't want to mess anything or anyone up running 110 with a flopping filter.
The Fast Ez has a AF setup and all was good with that. AF was 12.7 at WOT and the fuel system is up to snuff. The whole car is dialed in the best I could afford during the build. The only weak point I can think of would be in the way the air gets in. That low profile bonnet is LOW. I guess I should have given up on a cold air kit when the regular profile wouldn't fit under the hood, but I was hell bent at that point to have the cold air. When you have a hand held showing you just how hot the air is coming into the throttle body, it made me HAVE to have the cold air kit. Not the first mistake I ever made ,lol.
Im going to call Tim at Bullet, Monday and see what he thinks about the cam petering out at 5500 as a possibility. The car didn't spit, sputter or cut out. It just nosed over slightly and quit pulling hard past 5500. I honestly think I would have lowered my ET if I had shifted at 5200-5300, instead of holding it in gear.
I wish I could find some hard data on the spectra bonnet, but so far I cant find it.
