Gnari perfor,mance

[antrep3]

so i feel like a Di&@ posting about this product on the forum beings that stinger produces his own manifold but has anyone ran the gnari performance manifold and waste gate setups? was there noticeable gains in hp or in spool up??

[Stinger]

It's just a Chinese casted copy of an E6 with a WG flange added. Internally it actually has squarer corners where the individual ports meet the log which will hurt flow, while the larger ports will help if it's on a ported head with larger than stock ports (so the gains and losses offset each other).

[antrep3]

Ohh ok good to know, looks like I'll be saving up for your header kit

[Stinger]

I wasn't necessarily trying to point you in that direction either. An E6 (or ported E6) is a very good option for people who aren't trying to make a ton of power (375+) and are looking for daily driver reliability.

[antrep3]

Oh ok. How would you compare the spool up and power increase to your manifold ?

[Stinger]

I've not seen any back to back testing with the Gnari manifold, just looked at it internally and listened to what Bo thought when he looked at it. There is no reason for a log manifold to ever out perform a tube header in peak power. They will typically spool quicker because of the short distance between head and turbo (and because boost is a measure of restriction to flow through the engine).

But overall Im sure Ill benefit more If I go with your tube header. i wanted to ask you something else, I installed a catch can directly off the water separator and eliminated the pcv valve. i left the valve cover vent to the atmosphere and im still getting oil coming out of my oil cap and dipstick, not a tremendous amount but enough to make everything dirty, would you say thats because i dont have the valve cover vented enough? my compression is 150 across the board so i would assume i dont have any major blow by

[Stinger]

Depends greatly on how large the hose from the oil cooler (not water separator), how large the ID of any fittings you used is, and the design features of your catch can. A poorly sized catch can setup is no better than the stock PCV system.

[antrep3]

ohh ok. Im using 3/4 inch tubing to a custom catch can that i had made, its about 10 inchs high and used 3 inch stainless tubing with a filter inside of it

[Stinger]

How big is the opening going to the vent/filter on top of the can?

[antrep3]

its about half an inch

[Stinger]

It needs to be at least as large as the hose ID going into the can, preferably larger as you don't want it to have to pressurize the can to expel the gasses.
