I'd really love to drive your Evo sometime...

I'm sure we can arrange that. Remind me at the next meet or on the Shreveport cruise. Are you thinking about upgrading to a X?

RED = MAP ported exhaust manifold (SPC coated)
BLUE = MAP short-runner tubular exhaust manfiold (SPC coated)

I should have just done the MAP ported from the beginning...

BLUE = PPI "extreme" ported
RED = MAP short-runner
GREEN = MAP ported
(all were ceramic coated by SPC)

I'd love to see what you'd gain going w/ a high quality equal length runner manifold like the full-race

My guess is nothing based on my results with the short-runner tubular; it showed great gains over the PPI though. I think you need a larger turbo with more airflow to justify getting away from a cast manifold.

Kracka, can you talk about the cams for a moment?

You mentioned that you won't install cams into a DD car, for drivability reasons. What do cams do to the car in that respect? What kind of special instructions would you need to give people?

(I'm trying to understand if I want to do cams or not at some point)

Thanks.

I had cams in my IX. Basically, the biggest things that suffer are idle and low-speed drivability smoothness. Cams make a car less of a jump in and go affair; you have to learn the quirks of the car, how it behaves, etc. My IX was undrivable for most people. My [ex-]wife couldn't drive it, my parents couldn't, only a few other Evo-owner friends could...with my X, anyone can drive it. It still drives just as smooth as stock; if you can drive a stick-shift, you can drive my X.

There is no doubt I could see some nice gains in power with cams, but I'm just not willing to sacrifice the daily-drivability of it. Maybe if I ever pick up a second car again I'll consider doing a set of mild camshafts, but until then they're not something I'm interested in.

what cams did you have? I drove my friends IX the other day w/ GSC S1's and and AMS tune, and other than the slight lope in the exhaust note, I was unable to notice anything else.

FP4R's which are much more aggressive than S1's, they were more inline with S2's.

gotcha, that'll do it.

I have to completely disagree. Having a IX makes the drivability 100% better than an VIII and completely acceptable for daily driving. My cams are comparable to S3's with 12.1 mm of lift, and with MIVEC set to -4 in the idle cells, my idle is rock solid at 1000rpm.

Very nice, man! Can't wait to see the car at a meet!

MAP EF2.5 installed and tuned by Cobb yesterday while I was in Austin, TX for an event.

426whp
393wtq
27.69 psig (peak) holding a flat 26 past redline.

Still on 93-octane pump gas and stock cams! Solid gains over the EF2, but definitely lost some spool and response. This is with the 3" anti-surge cover, but MAP also sent me a 3" standard cover so I'm thinking if I swap that one on I'll gain back some spool and response. I'll talk to MAP about it and go from there. The car is definitely a beast for a DD, and I believe this is the farthest Cobb has ever pushed the stock cams and it's getting up there for pump gas numbers too. My previous results on the EF2 were 413/384; peak boost was right about the same, ~27psi. I think this is yet another good turbocharger option from MAP. While not replacing any of the current models, it's a good fit between the EF2 and EF3 as intended.

A second compressor cover you say?

Both covers have a 3" inlet for maximum airflow, one standard, one anti-surge.
