18 Manifold + Vortech V3

[kcc0521]

Did you use the throttle body spacer that came with the vortech kit when you installed your 2018 manifold? I left the spacer off because it didn't seem to fit with it on.

Hellhorseperformance said take it off. Great people to deal with.

Why did you pull the stock intake to 7400 and the 18 to 7000?

The graph and gains are pretty deceptive. You mean the 50 hp gains is exactly where the 1st run cuts off:headbonk:

So is the manifold worth 50 more hp? Umm its worth 50 more hp with 400 more rpm.

we brought it out more. if you're looking at the rpm next to the HP number, thats the RPM it made peak power at.

Peak up is still peak hp for both runs. That 2018 mani made more hp where the stock one started to flatline.

Sure the 2018 manifold is worth the money but the gains are at the top of the graph. If you want to compare how the 2018 is better look under the curve or figure out what the average hp is for both manis with the SAME peak rpm for each pull.

Do you have a picture of your vacuum routing? I used the EVAP port to tie my vacuum log in for boost reference but my log looked really bad and I am trying to determine if it in mechanical or tune related.

yeah it fit better with he spacer off

For boost i tapped into the brake booster to manifold port and added a check valve before the T for the boost. Ill post pictures in a bit

Keep in mind, the 742 run with stock mani is with IMRC's active and the 2018 manifold is with IMRC deleted. So thats why the gains are not much down low. We could of made way more down low but decided it was best to delete them.

I'm trying to decide whether to lock out or not to lock out with N/A 2016 W/3.31 gear. Suggestions.......

Tuners are saying IMRCs do not impact WOT in any way. :shrug:

you're right on that one. Disregard my uneducated answer :headbonk:

Thats why I dont understand why there is even lockouts, I have seen a lot of people including myself never have issues with the stock IMRC active.

Well first I locked them out because it seems no one has gotten it right so far (less headache). I also had the IMRC's break on me on my 16 manifold a couple months back.

Hey Velgen

ANy update on the pic showing how you tapped into the brake booster to manifold port and added a check valve before the T for the boost?

Thx
