Dyno Guesses & Bench Racing Forum - tbss cam and springs. buy??

Wow that's little . I have a Stock TBSS cam shaft and springs that i could sell . It's the same a LS6 (ZO6)
204/211, .525" 116lsa
+ retainers

friend said he will sell it all to me for $150, and that i could expect 20 whp and with tune maybe more?
tell me what you think, thanks!

If I remember correctly, there was a member who did a LS2 cam in his MCSS, got a lot of noise, and didn't gain much. I believe another member did one also, and didn't get much either.

No one really has done a successful cam swap and laid down great power and 1/4 mile times. Mongoose makes pretty good power, but he's spent a ton of cash and I don't think he's ran the 1/4 mile yet.

1. buy it
2. dyno your car
3. install it
4. tune it
5. dyno again
6. give us the results

6 easy steps to success!!

lol thats alot more money then i plan to spend, buying it and tuning it would be as far as i go, and telling u my new 1/4 time
im not sure if i want to buy it now though considering the posted "noise issue"

The noise issue I'm not sure what it was. It's an older post from a couple years ago. Just have to find the right combination of parts. Research it in our section, there's a bit of info you can find that pertains to this cam.

That's not an LS6 cam if the intake and exhaust you posted are correct.

I'd be more interested in using the 2000 LS1 Corvette cam with some 1.8 rockers.
P/N 12560968 (Y car cam)
198/209 115.5 LSA
.500/.500 1.7 Valve lift .529/.529 with 1.8's

Peak power at 5600 RPM in the LS1, and in a LS4 I'd say 5800 peak with a 6200-6300 shift.
Nice.. mild.. cheap, non DOD, cam for our engines. I'm sure we would see 25-30 whp with this cam and rockers.

Agreed!
Same dam dyno, same dam gear, on the same dam day!

Same damn dyno, same damn gear, on the same damn day!

Good luck with that. :emb: Unless you use an engine dyno.

Sittingmongoose did try a LS6 cam, didn't like the results and had to upgrade.

I don't see any reason in putting an off the shelf cam of any sort in these cars. The money you will be spending will be on supporting mods, parts, and labor rather than the camshaft itself (in the scheme of things). There's really no reason not to wait another month and save up the money you need to have a reputable shop, or comp, spec out a custom grind for you.

I dunno if we have any reputable shops around here. I could be wrong.

In Louisiana? Give Pat G or EPS a call. They make some of the BEST cam only numbers with LSx engines.

Location?

Baton Rouge, if I remember Correctly.

5.7l with 243 heads full bolt on car and an LS6 intake.

Decent drive for quality work. Whenever the time comes, I'll look 'em up.

custom grinds are usually only $25-50 more than a new off the shelfer

Patrick G is in Victoria TX, south of Houston. He's a mod here. He has the quickest N/A G8GT out there.

Correct, he grinds on EPS lobes and does a lot of work with Jeff @ EPS.

I went with this company for my cam; http://www.vincihiperformance.com/ Lots of experience in the field and great customer support

Oh that's right, you guys haven't heard how well NMP's car runs with his cam advanced...........:secret2:

Do tell.

I agree, no off the shelf cam is going to work very well with the LS4. The LS6 cam (BTW, there was 2 different ones). works good with the LS1 but its not quite right for the 5.3. I've probably beat this topic into the ground so ill let you guys figure it out. :eyes:

Do tell.

If he wanted to tell I'm sure he would have already. He probably will post results when he has hard data to give, thats just how he is, unless you ask for yourself.

Not to be a dick but I've been trying to tell people how to make power with these LS4's for a long time, but nobody wants to listen.

Ok so I'll tell you this, I'm expecting the car to trap at least 108 mph, probably higher.

If he had an intake swap it'd be crazy.

There were a few LS4 cars that were trapping 106-107MPH with Rockers, CAI/WAI, downpipe and tuning. 1BaddSS and supercatx. Raising the shiftpoints made a big diff as I recall.
1BADDSS was the first one too try the LS6 cam. It ended up being real noisy (with 1.8's) and made no diff in the 1/4. I blame this on the stock intake manifold and gearing. The Shift points would need to be raised too, and would hurt 1/4 mile times due to the fact his car was no longer toping the current gear after passing through the finishing beam.
Besides, the 119 LSA that the LS6 cam has is better suited for Manual trans cars with low rear gears. We need to keep it tight. Somewhere around 112-114. This narrows the powerband.
Intake manifold and the headers. Cam swap should be last. My only problem with the stocker is that it's a DOD grind. Other then that I think it has the potenial to hit 110 though the traps with std. bolt ons. Rockers are a must.

Great company. Roger, is the man when It comes to valvetrain and camshafts. It was truely an honor to speak with him. In fact, he really needs to write a book!
We spoke about a year ago and he recommended the BOSS cam. I ended up buying the TR 220/220 and then sold it and put the stocker back in:bang:
Waneted to go turbo instead. Now I'm broke and unemployed after this month:confused:

Chance707 is using the LS1 intake.

I think that if anybody in here wanted to get a cam in their car, a custom one from EPS would be the way to go. The challenge is trying to get one that will match the DOD characteristics. Otherwise, you will have to change the lifters out from DOD to non-DOD lifters. I am sure that they can make one for you and you can experience Great numbers under the power band of our engines. Especially since we have LS6 heads in our cars. If I were to consider this, I would go with a ls6 intake, headers, and a custom EPS cam. I would expect pretty respectable numbers from this setup with a good tune. Maybe around 315-330 fwhp range. From what I have read on this forum about the EPS cams, is that they have GREAT street manners and make a ton of power in LS1 and LS6 cars. The street manners are very comparable to a stock cam, so much that you can barely tell the car has a cam in it. I pitty the fool who tries to line up against you thinking that your car is stock. :D

You have been vocal on what to do with these cars for sure. But no one has really solid numbers yet on a cammed LS4 other than Mongoose so far. I'm sure NMP's car will put up some good numbers when he gets dyno'd without a doubt.

I'm hoping that my tax refund will get me to the dyno. Still waiting for the weather to clear up to do a video.:bang:

your joking right?

Lol I think he is.

I thought it was pretty clear that Nate did his [LS6] intake swap before the camshaft.

I think he's mocking me, back before the LS1/ LS6 intake swap was widely accepted, I use to swear the LS4 intake was the bottle neck, I'm sure O-BAMA remembers that.

Haha, you did beat the LS4 intake topic to death. Took a while for it to sink in, but it is pure garbage.

I've been under the impression that NMP was running the stock LS4 intake. I'm sorry if I'm mistaken, I can't remember every modification done to every car on here. I'm not sure how I was mocking you, I was simply stating that the motor would flow better with an intake swap. But hey, If his cam and intake swap only traps 2 mph higher than I did on a bad tune then maybe we should all reconsider putting a cam in these cars.

Chance707 is using the LS1 intake.

I wasn't talking about Ken. I quoted JDM's post talking about NMP's car. Should have been more clear, I suppose.

He's predicting 108+ traps. No track times that we know of yet.

The trap times aren't really important here. I'm much more concerned with why I was thrown under the truck for a mistaken intake manifold.

Maybe he thought you were being sarcastic about it. Possibly taken out of context.

That’s a good point. I’m hoping that this spring I can add some real data to this issue. Until then I would like to share some very nonscientific information. Last summer I was in a buddies Steeda and he ran a section of road from a standing stop to a street sign somewhat down the road. When he reached that street sign I looked over and mentally recorded his speed. The next day I did the same run and compared my results to his. Well today I was over in that area and reenacted last summer’s run with my new mods and I was somewhat disappointed with the small difference between the two runs. I think traction is the now the limiting factor in my build or perhaps driver skill.

Ken, please note that my post wasn't directed toward you. I was talking to jdm about Nmp's car.

thrown under the bus?? You gotta be kidding me, I thought your were being sarcastic. Besides the fact that Nate was the first person on here to complete the LS6 intake swap and publish his results on here, I thought you being a Mod would know this.

But hey, If his cam and intake swap only traps 2 mph higher than I did on a bad tune then maybe we should all reconsider putting a cam in these cars.

well maybe if you would post your mods so we had something to compare it to then we could have a pissing contest. Don't worry I'm sure your 106 trap speed will be more than smashed.

There's no need to get worked up, I understand that you just misunderstood. I'll spend the rest of my day memorizing everyone's modifications so that I don't upset you again. Please forgive me. :cheers:

EVERY mod I've ever done has been posted about. But I can understand where you could have missed something, so don't worry about it. I've even posted before and after times for the intake swap...

Let me know when you blow away a 106 trap speed...

No offense taken.
A cam swap can be very time consuming and costly, esp. when going the nonDOD route. Even though we have had a few cam swap threads and a few dyno numbers thrown around we still can't say what cam #1 or cam #2 with these XYZ mods. can do for our LS4 engines. I think this ongoing discussion is really good because it is touching on two points; when does modifying the LS4 engine cross the line of diminishing returns and when does the cost of a cam swap make sense. I can tell you this if I don’t get into the 12s NA this spring I will be very disappointed.

^^^ With a good tune and sticky tires it really shouldn't be any issue.

God I hope so, right now I have neither:bang:

intake swap + headers = cam swap worth it :chug:

still don't know why the agression is necessary but oh well, not even my car. We'll be sure to keep you posted. :nod:
