Overall the #'s seemed lower then I expected along with the HP peak # at 6k. Was satisfied with broad range of power over 400. But looking for your guys opinions. Car was street tuned, we are going to be hitting the track and a dyno and tweak it some more. Final result yielding 428RWHP/427RWTQ uncorrected

With that being said my last ls1 TSP v2 set up was dyno'd 411/383, and this set up feels so much faster. I wouldnt expect to feel 17hp difference. Undecided on which # was the in accurate one

This is like looking into a mirror lol! And with our hci being almost identical this is just to ironic lol. Mine made anywhere from 390-410 rwhp with the lq9, and with the old ls1 setup it made 405 rwhp with the Torquer 2 cam. Both runs on the same dyno as well. Now like you my new setup is noticeably faster than the old one but makes no more power on the dyno lol. I made a big thread about it last week. This just blows my mind....almost exact same setup....almost exact same experience on the dyno. Even our previous ls1 builds were practically identical for crying out loud lol

I know I feel ya, i read the entire thing. There is a group track meet I may go to next weekend, so at least then I can weigh my car next door to my shop at the concrete yard and have a trap speed to get a # as well. But im trying not to get caught up in it because of how much faster it feels.

I went from a dynojet to a dynocom though.

It makes me now wonder if there is something about this particular top end setup that doesn't mix well with the lq9. Have any theories lol?

I have no idea. The car runs ******* awesome though, you even said agianst the cobra there was a noticeable difference even after he added more power. My buddies cobra is at 567 /w whipple and torco. But we haven't really lined up.

I though maybe because we didn't have a tach signal from the car (or in the car since its to slow) but this dyno can calculate using roller speed. I don't know, there were a few 2010+ LS3 Camaros that went up after me that were cammed and the top one put out 445 and the other one did 430.

There is a local dynocom dyno to me so me and my tuner are going to go and mess with the timing a little more and compare. But I am lost also.

brians car? a dyno is just a measurement, dynos vary and is just a ballpark figure. if you wanna see how fast your car is just take it to the track and check your trap speeds. i wouldnt get all hung up on a dyno number imo.

OP, you seem to be more focused on the 17 hp gain being noticeable when the biggest noticeable increase is the 44 lbs of torque from the added cubes that is moving you quicker.

HCI2000SS

I've heard a few logical ideas so far but they still wouldn't explain why the car is "actually faster" then. The only thing that even remotely makes sense to me is it would have to be in the tuning...something in the tune that allows the car to reach its full potential on the street but not on the dyno. If it were the heads, exhaust, etc, etc...then it wouldn't be any faster on the street either. Who knows lol

"the biggest noticeable increase is the 44 lbs of torque from the added cubes that is moving you quicker."

I agree. The gains are about what I would expect from a "stroker" so to speak.

yeah I didn't think about that as far as the TQ goes.

But yeah they aren't many local tracks around but there is a group of guys going next saturday. I will try and get there soon. Im not that worried about it since the car feels so much quicker

Hmmm very interesting! My torque was still about 30 less than the hp on the lq9 and ls1 setups. The only difference is the torque curve is broader with the lq9

MyFirstLS1

What rpmwas your peak power at ?

HCI2000SS

iTrader: (2)

Peak hp was like 6200-6300 and tq like 4800.

Is it normal for that cam to peak so early? I think I remember it peaking at 6200-6300 in ls1s but carrying out really flat.

OP's seems to peak at 5700ish. I would not expect a 6.0 to eat up that much more RPM from the power band over a 5.7

Has the car been scanned to compare ambient MAP to WOT MAP for possible air intake restrictions?

HCI2000SS

iTrader: (2)

Oh wow, I didn't realize you were peaking that early OP. That definitely does not seem right to me at all. Even with my old LS1 HCI setup I still peeked around the same 6200 rpm. The only difference that i really noticed with the LQ9 was the torque curve being broader. But the peak torque still was at the same rpm with both the LS1 and LQ9

MyFirstLS1

iTrader: (8)

no i havent scanned to compare but that is something i can easily do. It was brutal as far as ambient and humidity that day.

The RPMS are also going to be based on dyno roller speed not my engine RPM since we didnt hook up a tach signal. There is another local dynocom I may go on before/after i bring it to the track

1989GTA

IMHO the long runner intake manifold is going to have something to say as to where the motor will peak. You can move that around somewhat but physics is physics.

As far as the torque , I believe dynocom dyno's usually give a higher torque reading just from the ones I've seen posted on the boards.

Was the first dyno you used a dynocom? From my experience dynocoms give funny TQ numbers because they typically have no rpm pickup (unless an aftermarket unit is added). I was expecting the HP to be higher too with a 6.0L with heads/cam but whatever. The true test is the track.

**** I forgot to look at the old dyno sheet. I believe the old #'s were on a dynojet though. Not 100%

Next saturday I should hit the track and we will probably mess with the timing a little more see how she does.
