I feel your pain. I know my cam isn't as big as yours I have the Hot Cam, LS6 intake, Yank 3600, and 3.73's. I was disappointed with my NA time as well I only ran a 12.6 at 108 on nitto555Rs. Threw a 100 shot on it and ran a 11.85 at 116, w/ 1.85 60'. I am hoping I just have too much stall for my cam. I was hoping to be in the 11's before the n20, but my fear is I just have a factory dog. However it has never been dyno tuned with current mods. Just hptuners by me.

 

^ I dont believe you dont have too much stall for your cam, I put a 3600 stall and 3.73's in a mostly stock (free mods) and dr's, 02 T/A firehawk and gained 4 tenths in my e.t...but lets stay with the op..still waiting for the dyno graph..

 

Your from Chicago.... So am I, Were did you get your Tune done???? Ill tell you your problem right away....

 

LS6 intake or similar/ported halfshafyed throttlebody/ a pulley/and a cutout and i bet you will find all your missing power....

 

TUne was done by Straightline Performance, I've had people tell me thats the reason and they cant tune and then I've had people say they do great work and tuning so Idk what to think, I will say they are great to deal with though no complaints whatsoever in that department.

As far as intake goes I figured it was assumed I had a lid on it and Im gonna do a ported TB soon as i get an ls6 or FAST intake. Idk guys maybe the car is just a dog but Im definetly not happy and am gonna be changing some things up in the near future for sure. I figure an MS4 with a 200 shot will satisfy me after this years dissapointments.

 

Oh and I will try and post up my dyno graph soon as I get my scanner working...its been acting up

 

dont sweat it dude, i also have the stock LS1 intake and heads, no underdrive pulley, and a 3600 stall. My car made 348 unlocked and 365 locked. @3460 race weight with OLD ET radials and NO suspension work i mustered a 11.90 @ 115.xx MPH.

 

You never answered my question about who did the install. Are you absolutely positive it's not off a tooth? Forget what everybody else's dyno numbers are, they are worthless. Focus on your trap number and your conditions. Most shops fudge the dynos to read numbers anyways, whatever makes the customer happy. If you can get dyno numbers for comparison, get other cammed LS1's on the same exact dyno (same shop).

Sure you are giving up some power with the intake, but my money says there is a bigger issue holding you back.

 

my car put down 351rwhp/355 rwtq with just Hooker long tubes, ORY and LM1 exhaust....and trapped 111mph.

somethings wrong. I added a MS3 cam and was trapping 116 through the stock catback.

 

Sorry but thought I mentioned a couple times that Straightline Performance did the cam install and a good friend of mine who works on an builds some pretty repuitable race cars did the converter and gear.

What exactly do you mean about off a tooth? I reread your post and am still unsure what you mean as I dont have much expierence with these(all my learning has come from this site)

 

Oh ya forgot to mention went to the track last night and managed a 12.2 at 111. Cut my 60 ft to 1.6x as well by messing with tire pressure and launch rpm a bit. Also managed to even pull the left wheel off the ground with my heavy *** 17's. That was new for me! Only mod I did was pull the maf screen out and mess with my launch an tire pressure so some its looking like I need to make some minor changes as well.

 

^LS6 intake/ported TB and I would venture to say you would hit high 11's. As for being off a tooth it means the cam to crankshaft alignment is off by one tooth when comparing the alignment dots that are located on the crank and cam gears. The cam rotates 1/2 as fast as the crank so it's possible to not get the dots exactly lined up during an install. This is why you should rotate the crank once the timing chain is on in the clockwise and counterclockwise direction to ensure those two dots are perfectly lined up.

 

Was the converter locked?

 

Get a ZO6 MAF, LS6 intake and a 85mm TB or port the stock one. That should give you almost 30 more hp imo.

 

Gotcha. I misread your post, I thought you meant they just did the tune. Interesting that you picked up 3 mph last time you went. 111 is better, but like others have said, still seems a little low (but it does come pretty close with where your dyno numbers are). What all did you change to pickup 3 mph? Was it fairly consistent 111's the whole time? What's the weather like there?

 

personally i think that cam is way too big for a stock ls1 motor.. the ls6 intake will help ALOT, probably gain 15-20 hp but the heads will not flow 600+ stock. getting some heads and a fast/ls6 intake will turn that into a bad ****.

 

That cam cant breathe with stock heads and intake up top. What do people expect from a cam only? Gotta do the whole package, heads, intake, cam and exhaust. 400rwhp is difficult with a cam only and usualy takes a bigger cam thats a dog on the bottom end. Sorry buddy, wanna play, gotta play. Look into some TFS or AFR heads.

 

A 231/235 is "way too big" for an LS1 motor?...are you serious! What do you recommend, a little 224?

 

I think he was referring to the lift on the cam and how it is pointless to have a cam with that much lift and heads that won't even come close to flowing what the cam would like to have. I see his point though, bottlenecking flow in the heads sure isn't going to help anything. Yea man you really need an ls6 intake at the least.

 

So did you get the heads back from TEA already? Looks like a good sized cam you picked as well...get that stuff together so we can see some results!
