Well lets just say it was kind of a dissapointing day, although the car came back with nothing broken so i guess thats a plus. Well we head out and get there around 10 and unload the car. I waited about half hour and warmed up the rear and made sure a clouple of big tire cars went down the track.

Well i basically unload it with the stock tune in it to get a baseline run or 2. Well the first 2 runs went almost exact same, 12.18@111.72 w/1.77 60' and 12.16@111.75 w/1.79 60'.

So i get back to the trailer and want to start to tune it. Well the damn laptop wouldnt let me log in. I tried everything and found out that computer took a crap on me. So i am at the track w/ no way to tune the damn car. I decide to make 2 more passes and pull the plugs. The next 2 runs were withing .01 of the first 2 another 12.18 and 12.19. The plugs were fricken bright white again.

I decide that the only think i can kind of do to change this is up the fuel pressure. The stock psi on the ls1 is 58psi so i upped it to 60. made a pass and ran a 11.91@113.8 w/1.71 60'. Well that is what i needed alot more fuel so i upped it to 62psi and made another pass and ran a 11.71@115.10 w/1.71 60'. This is all with the stock tuning.

Over all it was a decent day at the track. I could have made probably 10 more runs but didnt really see a point without tuning. Im sure with some tuning i will see some very low 11's if not some high 10's. This winter i am also going to put on an ls6 manifold and maybe do some head work. Goal for next year is 10.70's on motor and 9.50's on spray. O well im happy with getting in the 11's but know that there is still alot more in her.

 

It sucks that you couldn't tune it, but at least Murphy stepped in there instead of a 2-3 shift.

Sounds like it'll be a fast ride once you get it sorted out.

 

glad to see that you broke nothing and had a good day at the track. what rpm were you launching off that stall? You should be able to get 1.5X in the 60' when you can get everything to hook up better

 

some nice runs there Tim, but i didnt go damn it......all of my buddies backed out at the last minute......this is the reason i need my own truck so i can drag my own butt there.....oh well i think i am done for the season, i am gone next weekend and my buddies all want to go the weekend after thanksgiving.....but we will see i want to pull the car apart before it gets to cold

 

don't pull the car apart....looser motors run better on nitrous....i'm telling ya, keep it together and just spray it.

 

Yea i know my 60ft times suck reeally bad. Im not sure if it has something to do with not enough fuel or timing but it is lazy off the line. It pulls the front left tire about an inch. Its off the t-brake about 4500 but it really does feel sluggish. I just needed to get that computer hooked up and log my runs but that damn computer crapped out.
----------
Hell ya mike spray it till she blows then worry about building one. Yea loose motors will like nitrous more than fresh motors. Hell i can wait to spray the car one i get her running right.

 

if that's off the tbrake at 4500, your 60' sucks....i thought maybe those were footbrake runs. Definately need a laptop and datalog, sounds like it wants way more fuel since you had to raise the pressure. Good luck on it, remember if it was a carb, you wouldn't need a laptop...giggity giggity goo. I'm sure the FI lovers will disagree, but all i need is a quarter or some other coin to pull off the bowls and jets even if I had no tools available at all. This reminds me to jet up my secondaries for more power as well this winter.

 

Going carb actually crossed my mind with the ls1 a couple of times, but i love the driveablility of the car now and it kinda seems like a step from FI. It would definitley be easier to tune off the bat but in the long run i think it will be a good set up.If i can get my 60fts in the mid 1.4's to 1.5's ill be happy, that right there will drop me to 11.4s plus i believe tuning will get me another .4 to .5 as I should be trapping somewhere in the low 120's. I also have to ditch the ls1 intake over to my ls6 intake which is good for .2-.3 at the track. High 10's i feel are pretty attainable next year and that is with untoutched stock heads!!

 

sounds like a plan buddy. I definately would keep the LS1 fuel injected since they're a good setup from the factory and not very restrictive at all. Not to mention that 15 degree head angle...sooo nice. Good luck on high 10s on a n/a motor that should pull 20+ on the highway, definately jealous of that aspect.

 

i may keep it together, if i can find another 350 block to bore out, i plan on a 40 over, 6" rod, stroker crank with a roller cam around the 620 lift area......THEN I want to spray the snot out of it

 

gonna need a bigger stall and a better built rear end before you have those kind of dreams.

 

I think i saw a good one at Hooters In Orland Park. Ill go check it out with you if ya want.

 

yes i think we all should check on that rear end some more, perhaps when i'm sober I can ask if that rear end would like to eat dinner or stay at my place.

 

HAHAHA

I can see this going on for a while. LOL

 

the stall i know about.....but i am going to see how long i can get out of the stock 10 bolt.....once it has good axles and stuff

 

don't throw any cash into the 10 bolt, since it'll still break regardless once you can hook, hate to have you spend the bucks on girdles and axles and $450 posi's then still break stuff.

 

Its still a $1k cheaper than a 9 inch or 12 bolt swap even at that point.

My advice? Build it up and live with it and shop for a used or screamin' deal on a 9 inch or 12 bolt in the meantime.

They do take a lot more abuse than people give them credit for. The get hamemred on here cause most of them have high mileage to begin with and people are dropping the clutch at 4k w/ slicks on manuals lol

later

I did some research on building up the 10 bolts in our cars.....it is a whole hell of a lot cheaper, and there are guys running as quick as 9's in our cars with the small 10 bolts......plus is if i "happen" to run it on the street if some one were to glance under the car and see a 12 bolt or ford 9" kinda gives it away as something with power

plus i am going to run a spool once i completely redo the rear end

 

Man I cant wait to see this car in person! This seriously making me considering a LS1 swap of my own, the price is off set by the gas milage and driveablity and the easy tunning you can do on the fly. That and LS1s are getting Cheaper. Sweet Set up!!


Kevin

 

spool on the street? oh geez

I don't know a single car that hits the tires hard in the 9s that is running them. although four 10 bolts later i might have a clue under my camaro. Anywhere from 35k on them to 100k+ and they all broke. 3.42 and 3.73 broke all the time ripped the gears right off. Even the 4th gen rear broke on me at the track. This 9 bolt has been holding up really well for some reason though....makes me kinda wonder.

 

I am going to try to keep it original looking as much as possible, plus i am not running a trans brake yet, but if i do i am not going to go all out with stalling it out

 

Yea mike that 6" cowl doesnt make your car look like a racecar so yea i would say total sleeper

Just messing with ya. I know what you mean though about people seeing a 9" under there. They need to make something like this just opposite....12 to 10bolt cover(sleeper look)....

That is LAME!

 

I know, it must be those damn ricers making that waste of money. Who else would want to make thier car seem faster than it is.
