Hi guys, quick question! I'm upgrading my intake manifold on my evo9 MR and I'm wondering if purchasing this manifold would be a great upgrade from my stock manifold!
Seems Magnus V5 is preferred, skunk looses spool.
But I have not tried Skunk to have data supporting this assertion.
Let's see what tuners with experience say
I tested stock,ported and skunk in the same week and the results were pretty close on my stock engine with stock cams. Conditions favored the other intakes but the stock one still made good power overall. The dyno graph was within a few hp/tq everywhere. Given these results I would say that At 500whp or less the stock unported was fine. The tests should be different with aggressive cams and a much larger turbo/ more rpm.I would stay with the stock manifold unless you are going to make power over 7600 and up. Thats when the additional flow of a ported stocker or other manifold will help IMO. All of the aftermarket manifolds including the skunk and magnus are really well done.
The skunk 2 lost some of the throttle response/snap compared to the stock intake on the street although the graph was close.
Mitsubishi knew what they were doing when they designed the stock one.
I would spend the money towards injectors/e85 and just make 400/400 or do a turbo upgrade.
Abacus,
Your findings are what many have experienced, when not trying to post/demo something for vendor but to simply test for themselves as in for race application and such.
Even 65-70mm TB, similarly turns out to be hard to measure benefits.
Dyno and tuning is by nature flexible, so you can add a degree of timing advance, lean out a tiny bit and show look- its making more power. Few do apples to apples.
I'd say that stock is great, and Magnus has shown to offer an advantage - but most cars with it are featuring large full frame turbos aggressive cams and more. So on stock-ish turbo simply choosing the best turbo and supporting fuel/flow mods and set of cams is best bang for the buck by far.
If I was sorting this car out, I would be choosing between HKS 7460 for response and all around power on budget, and EFR7163 TS T4 for more mid-top end at higher price.
For cams GSC S2 seem to really be the darling of us all.
thank you guys for all the help!!! I will use my stock intake manifold until I reach the limit of it and then I will be looking forward on upgrading the manifold. This thread helped me out to focus on somewhere else of the engine. I will continue my research on turbos. I already decided to use GSC s2 cams with upgraded springs.
I would not recommend using GSC springs so go with Kiggley's. Many folks had springs break, taking out the motor. GSC would blame the customer stating it was installed incorrectly, which I suspect is complete garbage. I had one snap after a few thousand miles of driving. Called GSC and they were only willing to send me 1 new spring. Long story short, purchased a set of Kiggley's.
