How much HP do you think I gained?

Hey guys. Very curious if these mods even add power to my stock tune zl1.

I have a Roto-Fab CAI, 87 Ported Mamo TB, and secondary cats cut, along with a CORSA X-PIPE.

Would these atleast make me gain some power?

Rapid_blue_zl1_22 · 12-31-2022, 12:40 PM

Yes, It should gain a little bit. I would think anywhere from 20-30 RWHP gain. Do a before and after dyno to find out. Exhaust doesn't really do anything, but everything else should be some gain.

Edit: I just realized i typed 20-50, I meant 20-30. I fixed it...haha

Not likely without tune. Maybe 5-10 if that. The ZL1 is a strange beast compared to cars of the past. Its tuned so intricately that any changes to its mechanical setup, results in the PCM/TCM counteracting what you added.

Without a tune, most boltons are worth nothing.

That isn't true, a ported blower will add 50-70 RWHP without a tune. Other small bolt-ons such as TB and intake will also add small amounts of power.

Here is a video of LME putting a Kong ported blower on a CT5-V blackwing with a 60 RWHP gain on a stock tune. The CT5-V's can't be tuned yet.

With a stock tune... i would guess 10-15rwhp

But my ported 95mm TB, and get a tune and i would guess 25-30rwhp

Z OH 6 · 12-31-2022, 01:27 PM

10whp at the most.

In terms of additional gains, a DSX lower pulley for $115 might be the absolute lowest priced mod to gain a little more power. No tune required.

An E85 Flex Fuel ethanol kit for $250 plus a $500 tune would probably be next lowest.

I feel like mine benifited to my cold air kit alone. I believe it is the best cold air kit on the market shaming the much fabeled Rotofab.
AFE Track in carbon fiber. I know it walks my buddies Hellcat even at triple diget speeds.

SJFGTO · 12-31-2022, 07:20 PM

0-10HP. 15 on a generous dyno.

CW3SF · 12-31-2022, 07:44 PM

15-20 hp primarily from the secondary cat delete.

I still think the Moroso supercharger cooling expansion tank is the first mod needed for the LT4. I was getting inconsistent power at the track, maybe on the street before. As it is I can break loose in 3rd with the SC3Rs if the tires are the slightest bit cold. I think the guys advocating e85 are otherwise on to something.
