Dynamometer Results & Comparisons - 235/243 LSR cam results

car is a 05 gto ls2 current mods were lt headers, cam is 235/243 621/624 113 lsa comp lsr, at 6500 car gained 79rwhp and at peak hp gains were 69rwhp at 3000 rpm torque was up 53 lb ft. ill post a graph later today

are there flycuts on the pistons? how is the driveabilty. Also what were the before and after numbers?

no flycutting driveability is suprisingly great (great tuner) and before with just headers was 349 and after cam 414

Nice gains, did you mean LSL lobe cam or that LSR just the name of the cam?

Stock heads right ?? I was going to say with a set of milled heads you'd have no room.

Awesome results though. How's the valvetrain setup ? and how's she like those big lifts and durations on that set of lobes ??

yeah they are lsl lobes and yes they are stock heads

Do you have the graph by chance ?

likns dead... and are they LSL or LSx lobes.... too lazy to look em up.

^^^^Also curious about a graph^^^^

likns dead... and are they LSL or LSx lobes.... too lazy to look em up.

The exhaust is an LSL unsure on the intake.

The LSR cam series is built on the LSL lobes

^correct lsr cam lsl lobes, and im trying to get the graph up

Itch your heads and do it...Btw nice results buddy :devil:

peace

the customer was very excited with the results! and im a believer in degreeing cams, since ive been doing it on my installs ive seen more repeatable and better results, even with the size of this cam, power and torque was gained throughout the entire curve even at 1500 rpm torque was up by about 18 lb ft!

Power looks good! Nice curve!

do you have a graph with the HP/TQ with an RPM scaling? Looks like this cam is begging for heads.

yeah i will get one up of torque

Very nice hp!!! With a Fast 90,ported t/b,and u/d pulley should be 430-440hp

on similar setups we have seen 22-30 rwhp by adding the fast 92mm setup

seems like an very nice gain what was the torque number?

408tq

great torque numbers as well :) the car is a stick I take it?

Looks like a good cam. James is a damn good tuner so it should drive great.

Congrats

Nice gains.

yeah it's a stick, and yeah James does a great job, we are glad to have him here at the shop now!!! i take it you have had him tune your car

specs look similar to a G5x3.

yeah it's a stick, and yeah James does a great job, we are glad to have him here at the shop now!!! i take it you have had him tune your car

No I am friends with all the gulfcoast crew and a few of the Mobile crew. I went to his shop with a friend while he tune is car and he done a great job.

I have my own efi but get help here and there from Geoff. he use to own Thunder racing. He also has my car idleing great with a big cam.

thats cool, James moved over to our shop a few weeks ago, so if you come down here again to have something tuned, give me a shout!

This is encouraging!! I am installing the 54-461-11: 239-247, .624-.624, 114LS. I can't wait to see the comparison to the 54-446-11: 232-234, .595-.598, 112LS. They both have a range of 2400-7200. I'm hoping to get into the 500+RWHP range. If I'm lucky, I will also have the FAST 92 ported. Great Numbers, Crazy!

NICE....

Great to see the LSR/LSL cams are working out awesome. I plan on running one in my truck soon, its all apart. My cam wont be that big though....223/227 most likely.

Very nice results... the driveability I mean.

I know that James puts in the work to get them right and he knows what he is doing. craze4speed, I am sure that he will be an asset.

any track results from this bad boy yet?

How about an idle/sound clip? That is the exact cam I'm putting in my car and I'm very curious as to what it will sound like.

I'm doing a cam similar to that in about a month or so; whenever my short block is finished being rebuilt. Cam is 235/243 .620/.623 on 111+4 lsa LSL lobes. Have a 90/90 fast and will be adding ud pulley. I milled my PRC ls6 head to 61cc to bump compression up. We'll see what she'll do.

Great results! Can we get a sound clip???

Great results! Can we get a sound clip???
I have this same cam only difference being its on a 112+4 LSA heres a sound clip. bear in mind this was recorded right after install and the tuning wasnt perfect. Thanks to FROST it now drives like a dream and runs like a raped ape at WOT. :)

Hey Detroitmuscle, did you have to flycut your pistons when running that much lift and 110 lsa? What is your ptv clearance?
i am getting a 235/240 .621/.609 111+1 cam and i'm worried that i'll have to flycut on my ls1.
Thanks!

I did not have to fly cut my pistons, I am running ETP 5.3 heads and GM MLS gaskets and I had at least .100" of clearance.

where can we get more info on these LSL lobe cams?
i have been searching, and must not be looking in the right places.
thanks!!

Currently running a ls2 with honker coldair box, ported t/b with a fast 92mm intake and kooks 1 7/8 lngtubes w/cats B&B exh. making 410rwhp & 403ftq , will be adding patriot 243's harlandsharp rocker arms 1.7 and a comps 238/242 610,604 on a 115 lsa, CAN'T WAIT TO SEE THE RESULTS.:nod:

Check out comps website. LSL/LSK/LSR lobes are similiar, I liked the way the LSR lobes looked personally but I am not sure how fond I am of Comps shelf specs. I believe some vendors are beggining to play around with the LSR lobes more and more and should make great power with good flowing heads.

Chris, thanks for the response!
i tried comps site, but didn't really give me details on these lobes. i'll try again.
i was considering a 243/251 or a 239/247 for an ls3 418 stroker.

Here is a list of their N/A cams. Seems like Comp really liked the 16 degree split on a cam that would be directed more towards your app. I would try to stay closer to the 114lsa, as the stroked motors dont always need a tighter seperation. I am sure Pat.G, Predator, or Ed curtis can point you more towards the right direction here.

hey, Chris,

wow! thanks!
i already spoke to Ed Curtis. i like his cams very much, and have had two of them :D.. the reason for considering any of these ones is as a result of trying to be a little "open minded", just doing research to make a more educated decision. i have seen results on my first choice. now, i am seeing results, and very nice btw, with these lobes.

sent you a pm.

...Seems like Comp really liked the 16 degree split on a cam that would be directed more towards your app. I would try to stay closer to the 114lsa, as the stroked motors dont always need a tighter seperation.

sorry, i forgot to mention, i am using cathedral port heads.
i was thinking 113+3lsa, or so. your thoughts?
bold faced-that is interesting.

I dont want to jump off topic here so I shot you a PM.

Sorry OP

yes, OP, sorry. i got carried away.
but, it was all prompted by your great results. thanks!

New news about my cam i just got, I pulled the trigger on Speed Inc's SI6 cam 235/240 .621/.609 111 lsa and to my surprise i got it and the comp cam card says 235/240 .643/.609 111+1 lsa........ wow that's crazy for a C5 6 speed TEA 5.3L heads isn't it? According to Larry i should be still ok on ptv clearance i guess we'll see. Oh btw, my point of the story is this cam has LSK lobes and the .621/.609 lift has LSR lobes.

I am going to bring this thread back from the dead because I am thinking about putting this in my ls2. First of all 349 with headers is low. A ls2 with long tubes should be about 375rwhp in a m6. So if this gains 79rwhp you should see about 450rwhp and nearly 470rwhp with fast, lt's, cai. I know Iam bench racing here but just estimating and pointing out that ls2's with lt's make more than 349. Has anyone else tried this cam, if so post your results, thanks.

You'll still be fine on ptv but that's not what you ordered. I'd send it back to speed inc and ask for what you paid for. The LSK lobe is violent. It is VERY hard on the springs and I know a few top LS engine builders won't run them ever for anything. They're also very hard to control at high rpms, especially without lightweight parts like titanium valves.

Someone fucked up and ordered or ground the wrong lobe, you should get what you ordered.

this is true, i was running longtubes and a CAI before and i was at 370rwhp

I'm using the original posters cam in my 402 stroker build and should have the results this week. fwiw

just got mine tuned yesterday...its a 2000 trans am m6 with a stock l92 bottom end, prc stage 2.5 5.3 heads roughly 11.46:1 compression 235/243 .621/.624 111 cam, pacesetter headers, no cats, magnaflow cat back, unported fast 92 w. nw 92 tbody, moser 12 bolt with 4.10 gears, tsp 100mm maf, and it put down 473 whp and 436 foot pounds on a mustang dyno...working on getting the graph up

Holy crap that's awesome! Especially on a mustang dyno. I got the same cam going in a very similar motor. I got a 1999 TA M6 forged 347, PRC Stage 1 LS6 head milled to 60cc, Pacesetter headers, no cats, flowmaster merge with cutout, hooker catback, hand ported 90/90, and Moser 9inch 3.89 gears. I hope I get the same results with a slightly smaller motor. Would love to see the graph whenever you can get it posted up.

this is the graph before the 100mm maf, 104mm lid, and the slowhawk tune..should have the new one up soon tho

I have this cam and it put down 468rwhp and 439rwtq with the mods in my sig. Thats using the stock ls2 intake and throttle body also.fwiw

This Cam is impressive imho

i like the cam alot also, our power looks to be very close. thats pretty impresive with stock ls2 intake and tbody..i did trap close to 123 untuned without the maf and new lid last week in a 3700 pound car in 94 degree and very humid weather

Was that the test and tune, Corky? I'll get the DA if you gimme a time/date.

ya huh...it was 7-10-10...around 9-10 in the morning

deacent gain

ya huh...it was 7-10-10...around 9-10 in the morning

It shoulda been about +1900-2000 feet

Track Elevation: 90ft
Air Temperature: 80.8F
Barometric Pressure: 29.825inHg
Relative Humidty: 70.5%

Density Altitude: 1942 feet
Relative Density: 94.44 %

Had the same duration cam with a lot more lift in it in my old 346. Good cam and ran like a raped ape once I put the FAST intake on it. It was paired up with a set of 243's and put down 45x/40x.

heres the graph sorry for the shit quality

2yrs old I know but what are some of these car's running NA at the track? My dyno numbers are quite a bit lower than most of these but with a slipping 4L60E still managed 11.7@116mph.

Here is the dyno graph from Holley LSFest 2011:
http://a6.sphotos.ak.fbcdn.net/hphotos-ak-snc7/310571_10150371117773343_500443342_10166687_193132 3924_n.jpg

And here is a dyno graph after a little AFR/timing tweaking on our dyno:
http://a3.sphotos.ak.fbcdn.net/hphotos-ak-ash4/407004_10150608622588343_500443342_11263048_149191 3579_n.jpg

My setup dynoed a little higher then yours but our track times are very similar. I ran an 11.7@117 my 60 foot wasnt terrific so I would say a it had a low 11.6 high 11.5 in it. I put a rod through the block so we'll never know.

I went 11.41 @ 125/126 in better air and never got to run it again that year. Had the fast ported and went for a retune and had valve train issues on the dyno. Still working on clearing that all up

I know this threads old, but just put this 235/243 113lsa cam in my LS1 383 stroker, made 322rwkw (431rhwp) and 660nm of torque through an 4l60e gearbox with a 3600 stall convertor and 3.07 rear diff gears.
have 1-7/8 headers and fast 102mm manifold/tb setup, ported heads and bigger valves.
Had torque and power curve basically identical to the first dyno graph on page 1.

Got a decent choppy idle and goes like a rocket when the throttle is applied.
