The general consensus on my overheating issue is it is oil temp related, and will require some custom oil cooler work, similar to what the Tyspeed guys did.
As for IATs, the Evo 2 Comp did perform better than the Dinan, even while I increased power significantly from Dinantronics to BM3 Stg 2H E30. If you run an Emix on track, the impact from any increase in IATs, including timing pull, is reduced. You can see this in the many 93 octane, 100 octane, and various Emix logs I've posted.
So, I'm not willing to give up my better throttle response during the 75% of time I drive my car on the street, vs reducing IATs by 10F during the 25% of time I'm on track bc the impact of 10F when running an Emix really isn't noticeable.
My interest in all this reemerged when the Evo 3 came out b/c it seemed to give the best of everything, but it apparently doesn't fit the M2 and I haven't seen any independent testing.
If someone who's had an Evo 2 Comp could chime in independently regarding their experiences jumping to the CSF or VRSF IC's, and can show that they reduced IATs by an additional 20F over the Wagner during a 30-45-min 95F+ summer track day, and they can say subjectively that they don't notice worse throttle response when on/off the gas in stop & go traffic, then I'm all ears.
Unfortunately, it sounds like I may need to be that guinea pig, unless a forum member can pipe up. |
I read you posts in detail multiple times, including last night. Yes, your temp increases were more gradual - but that was because you are running a flash tune vs piggyback and a lower cell count on the catalyst (Which drops egts) I’m saying this as definitive fact - it’s not as good of a track intercooler as the others. It’s physically smaller, and every review against similar coolers (the VRSF one featured above) proves there is PLENTY left to improve.
I agree, for the street it’s great. I’ve been looking for a new cooler and I don’t want excess lag myself, because I daily drive the car. But I personally can’t justify paying more for a less capable (in absolute sense) intercooler because of what may amount to an imperceivable amount of lag. Again, that’s just me. If it were major lag spikes (like I heard the CFS caused on the single scroll turbo that
FaRKle! runs) yeah, I might be more inclined to lean in that direction.
I’m just curious about this VRSF one now, because it’s on sale - and it’s god plenty of headroom for my needs. I hope to be tracking the car more frequently and don’t want to run into IAT issues.
