Ok guys looking for a little insight on where to go next on my set up, picked this car up the way it is a few months back with plans to push it a bit further. New to LS1 stuff but not to racing, car went 7.0 at 96 and 11.1 at 120 so far with the current set up.

Stock LS1 bottom end
799 Heads
TSP 233/239 cam with harden pushrods, comp 918 springs
LS6 Intake with Ported TB
1 7/8 Long tubes true duals

Has 4l60 with 4k Stall and just installed 9" with 4.10s also has 42lbs injectors and 255 pump.

I haven't had the car dynod or tuned but sheets he showed me showed 396hp @ 5900 and 452tq @ 3500 when he had it tuned, I pretty sure tune isn't spot on by any means.

I was planning to send the heads to TSP for their CNC service and probably a more max effort style cam MS4 or something they recommend to work with the heads. I would assume at that point I would be needed to jump up from the LS6 intake to a Fast or something been seeing things about the MSD intake. Not 100% sure on what size fast or if another intake would be better suited. Or if going with the TSP cam as apposed to another manufacturer would give better results, or even reusing my current cam.

Car is a weekend warrior not a DD by any means, but I do street drive to meets and track or to get ice cream LOL. Would love to get the car in the 6s and 10s I know I'm not far off but wouldn't mind getting deeper in if possible.

 

One observation. With that cam peak torque should be 4800-5000 rpm and peak power should be 6300-6600, and you should be able to carry to 7k easily. so with that said...

1. Degree your cam. Make sure either the cam or timing kit is not overlay advanced. Your numbers indicate an overly advanced cam.

2. Compression. Mill your heads to 60 cc if not already done that will take far better advantage of the current cam or and other cam you throw at it.

3. Intake. Skip the ls6. You should be thinking fast intake with that cam. I would do a 102, but even a 92 would be significant for you.

 

Cool that's about where I was thinking. I figured when I did the CNC port I could have the heads milled at the same time currently they are stock touched up, at least that's what I was told. Apparently there were some tranny issues on the dyno when it was tuned and they only went to about 6000rpm. I'm guessing there's a bit more in it as it sits but winter is coming and trying to figure out where I'm going next with the car.

 

Yeah, TSP will mill your heads no extra charge if they do the CNC port/valve job. They are good, AND reasonable!

 

Well that's just awesome lol I was planning to reach out to them on this but didn't want to lock myself into only their products, not that there is anything wrong but keeping my options open for now.

 

Don't go larger cam. The cam you have is about as big as you can go with out diminishing returns. If it already isn't at that point. Bigger is not better at this point.

100% agree with Darth's post also, he is the master around here and I would absolutely degree the cam if he says you should. He's cam yoda.

Do a FAST and do the heads. TSP port job, BOWL BLEND and valve job will make a ton of difference along with milling for more compression. I believe this is standard issue on their port work but ask and make sure. Each piece of it is important.

For what it's worth, even if you do all that you aren't gonna gain much peak power over your current cam but you will sacrifice low end, driveability and tuneability. Could end up with a slower car too if your average power is down. Peak power is cool but it isn't the fastest setup.

Then make sure your intake and exhaust are optimized. If you don't have headers and true duals. Do that.

You'll need a lid and tube to go with the larger FAST. The 92 is excellent also like darth said and you can reuse your LS1 rails and injectors with the 92. The 102 is excellent but comes with more headaches.

 

Will for sure look into the timing once I dig into the car. This cam seems to have a good rep from what I've seen wasn't sure if something would fit the the freer flowing heads once upgraded.

 

I would send the heads TEA if you have no budget on head porting.... otherwise Texas Speed do good for the money.

 

I don't necessarily have a budget in mind but this is not my only toy, so need to spread it around a bit.

 

That cam is begging to be fed more air. I'd leave the cam and focus on feeding it. And letting it ****.

 

Was able to get graph from original owner, I'm thinking the high tq number is from the stall? Correct me if I'm wrong.

 

more than likely that is correct
Also looks like it wasn't falling off and would have pulled well passed the 6k mark it got shut down at

 

Looks good and looks like converter flash there.

I just went back and read your first post. Man that thing is rolling for having a ls6 intake and stock heads. Is the car real light? 7.0/11.1 is impressive. What's that thing 60 foot?

You've got exh and cam covered. I would not go bigger on the cam, I've seen a lot of huge cam cars run slower than 7.0. Do the heads and a FAST and rev it to 7k shift points

 

I run the same cam and it likes to be shifted at 7000. Its very rev happy thats for sure. What was your 60' on that 11.1 pass?

 

Went out last Saturday and ran 7.0s all day with 1.46-1.48 60s. Car has the basic gutting tubular front end parts, I'm guessing it is 31-3200 with the 9" now in it. I'm around 200. I have scales at home that I've been meaning to get the car on, might do that tonight actually because I've been meaning to since I got the car. Car came with some good parts thats why I jumped on it SA adjustable QA1 shocks all around. I have videos of the passes I need to figure out how to post them... I'll put them on youtube then link them.

 

Hopefully this works LOL

 

It's doing damn good for what it's got, but lol at the 4x4 lift kit on that thing

To post a youtube video just copy the address in the address bar and paste the link here in the message box and the vid will pop right up without all the coding etc you see in your post

 

Yeaaaaa I literally got the 9" in lowered the jack got in and drove to the track, monster trucking at its finest LOL I did the heater hose mod last night to get things back in check.

 

Thats really awesome, great times for the mods! the 60' is out standing

 

Niiiiiiice!
