My Evo IX dyno session

[scheides]

No different than DSM stuff. Ported runners to match head and port outlet into turbine to match gasket. Do the same on the turbine housing and that's about it.

I have pics of the stuff from my car here:

The lean cruise 'mod' is just a tuned part of the map, and then tweaking the crossover point to open-loop mode.

I did not see the nsx or I would have drooled more, I've seen it around elite while wrenching a few audis with ktan and that is a damn nice car. PLEASE post up here results from tuning the thing, and PLEASE come take me for a ride when it warms up!

I am jealous hughes! My VIII put down 'only' 266whp when it was first tuned, maybe might have hit 275whp with a better parts combo. This car is 50whp over that!

Yeah it is pretty crazy. When Luke (9guy9) had Shane tune his 2.3l Evo we were a little dissapointed with the power but very impressed with the torque. I dont remember the numbers exactly but it was over 300tq and upper 200s hp with out any porting but standard bolt ons. I cant remember if he had cams or not either but I think he might have.

Either way, those IXs are nuts, make the VIIIs look like sallys mod for mod.

Very impressive!

Thats pretty bad ass! What are your plans for it?

Right now probably just drive it and have a ton of fun! It'll get more mods slowly, but nothing extreme is in the works since I hope this car will be my reliable DD for years to come. I'd like to get a GM boost control solenoid to hold boost better up top and I wouldn't mind doing cams in the near future.

Joe - I did see the red 1G but had no idea it was yours. It looked pretty clean and to be in nice shape (as far as I could tell just looking through the window from the dyno room). What kind of clutch issues are you having?

Mo - I did not see the blue NSX, but if I had I am sure I would have gawked a bit. I was gawking at a hot looking white STI though :)

As far as the porting is concerned Scheides summed it up pretty well. The exhaust manifold is ported just like a DSM manifold is done, then it is JETHot coated or whatever its called. For the turbine housing we just gasket-matched and smoothed things out a bit down into the housing. Nothing extreme, just enough to smooth the flow. The ceramic coated o2 housings come decent, but we did do some grinding on the welds to smooth things out and opened up the wastegate passage a tiny bit more. We also hacked up the stock o2 housing heat shield to fit over the tubular unit to keep as much heat in the exhaust/out of the engine bay as possible.

Nice, i can say that you (kracka) and other evo 9s have swayed me a lot more toward one in the future, no where in teh near one though.

[Swifty1638]

yea, I wasn't a fan of the mivec..still don't know if I am. But, for right now, I don't care for the payments..still...a definate car on my list to own.
