It's like all the other companies that do a dyno...but of course use the small lid z06 and then their own lid and are shocked there is a change.

He did dyno them though...

Not disagreeing with you. Certainly the Rotofab flows air and probably alot more so with a modified car. However, I still have concerns about heatsoak with intakes that aren't completely sealed. Especially when ambient temperatures are over 80 degrees. That's why I went with a Green Filter on my relatively stock car over the Rotofab.

Yup I've spoken with him before. He's been around here longer than he's had his current shop open. His shop is very close to me. Always seen good things from him.

E50 and upper with no fueling mods???

Yeah....thats my bad. I saw the thumbnail and thought it was an older lid video with a early z06.



This video was actually pretty solid. I have to say though, the "gains" could just as well be minor dyno "error" or 1 thing or another being cooler. A 5hp and 2tq gain isn't exactly showing much.



But also as he said, I think after porting these blower and alittle more mods, the aftermarket lids may start to shine over factory.

Low side is needed. Didn't mention it because it's mandatory and part of any Flex Fuel setup we do.

For sure, all of these could be within a margin of variability, but at least he did the test as scientifically as possible to eliminate as many variables as possible. This video should not be about which lid to choose based on which one gives you more power, we should all know by now that lids don't gain enough power if any to matter, it's all about the sound, look, and price, unless you have a 2015-2016 Z06 in which case, the gains are much more significant. We'll see what part two shows on a car with a lot more airflow, maybe then there will be some decisions to be made on which lid to choose for more power.

what is gain (e % and rough hp) over same setup without low side?
Thinking of either doing this or the new katech drop in pumps next. Katech pumps seem to be able to output much more. (in theory)

It varies. 2022+ ZL1's seem to have a stronger OEM low side (allegedly its the C7 ZR1 low side).

You certainly don't need anything more than a JMS BAP for this level of mods on E50 for any year ZL1.

Found out my ARH header cats were gone (after 5k miles) as I was doing an oil change. Replaced with GESI high flow cats and went back to the NPP muffler after removing the AWE Touring mufflers (just too loud with my build).

What I discovered was I can now really hear that blower whine after having the Kong Xport done with the WeaponX lid. So yes, these lids will allow more sound with a ported blower spinning faster but, doubt any negligible hp increase.

Yea, I could hardly hear any blower whine with my previous exhaust setup, now with NPP functionality again, I can hear the blower again, ported blower with stock lid and damper removed. I will eventually buy a lid but waiting to see Part 2 of this test on a modified LT4. I'll probably go with DSX anyway just because of the price and customization options.

No shit? someone should do testing on that. pretty sure a lot of guys would switch over to that to avoid tapping into tank if true...

And yeah it might be overkill at that level but if you are already spending the money to upgrade low side why not give yourself some head room to 1000

Side bar: I just got tuned on e50/headers, i think i want to tune tcm next. Does it have to be pulled and sent to HP and how much do you charge for a TCM tune?

I have tested it and it seems to hold true. The 1LE SS cars get the ZL1 low side pump which I assume is now the C7 ZR1 low side from 2022+. No REAL proof on this other than I see the 2019 Z06's (with proven ZR1 low side) and 2022+ ZL1's hold low side pressure better. It's not a huge amount but it is noticeable. If I had to guess they are about 10% more capable in stock form and 25% more capable with a JMS voltage booster.

TCM tune is a must IMO if you're not stock. But there are also things in the ECU that go hand in hand with TCM tuning. email me for TCM tuning at jason at snackbartuning dot com.
