Hey guys, I’ve been searching for a dyno graph showing the power/torque curves of a stock 6th gen vs one with the Lt2 IM + Roto Fab (on 93 octane) laid on top of each other. I know more or less what folks have seen in regards to peak gains but I want to see the entire pull and how it compares to the stock curve. Thanks!

Well I can't find an overlay if that is what you need but GPI talks about it here. However that is without a rotofab. Just comparing LT1 to LT2 intakes on E70



Lethal Garage did a test on the rotofab vs stock intake and his video does have dyno charts

Here's that video:



Even though Lethal's video shows no gains with a rotofab outside of torque, there are other videos of other intakes that do show hp gains. For example my K&N was tested to produce up to 9hp with a tune. Obviously taken with a grain of salt. But you might be able to draw your own conclusions based on these.

Otherwise, hopefully someone might have a screenshot of what you are needing.

Sorry that's about all I was able to find off a quick search.

That's a good video and worth watching. However, that's a pretty happy dyno they have and pretty high numbers for just E85. So, don't get wrapped up in dyno numbers as they'll drive you crazy. Here some real world numbers from two of my cars
2016 C7
Bone stock with 555r2 drag radials 305-35-19 12.06@116 Did not dyno stock
E72 and tune 434 rwhp and ran 11.58@121
E65, Ported Lt1 IM, Ported stock TB, stock CAI 1 7/8 long tubes x pipe, made 452 or close to that ran 11.00@125
E65, Ported MSD, Ported 95MM TB, stock CAI 1 7/8 long tubes xpipe and made 461/481, ran 10.90@128 w/60ft 1.56
2022 Lt1 Camaro, didn't run it stock and did not dyno when stock
E65/tune and Rotofab, 305-35-20 Nitto 555r2s made 431/441, ran 11.78@120 w/60' 1.78
E65/tune and ported Lt2 and stock 95mm TB, Rotofab CAI Nitto 555r2s made 436/441 ran 11.64@121 w/60' 1.72.
So, as you can see some gains were small but showed up better at the track, neither car were on the dyno when stock but most make 395 to 405 bone stock. These numbers could be off by 1 or 2 rwhp as I'm trying to remember as I'm typing. The Ets and mph are as you see them

Appreciate it, I’ll check that out.

Those are some impressive times with just bolt-ons and E! I’m really looking forward to taking time off from work and installing parts. I’ll be looking for a reputable tuner in Central Texas.

Thanks for the motivation.
