What type of dyno were you on? I am ASSuming a 2wd dynojet.

Damn man awesome numbers. That chart makes me want to go out and do some more tuning on my car. I love the 64 power band. Having 500hp from 5-8k is a helluva ride.

Turbine housing is a .68 a/r. The dynoing was done at www.arfabrication.com on an AWD dynojet.

As for the powerband, yea, it's kickass! Lots of 2.0 guys look at that and don't like it.....or maybe don't understand it.

The mod list you linked to shows the C2DI and custom coil setup on there? 32 PSI is pretty good, I started seeing misfire at the stock plug gap around 25-26PSI, at a much richer AF ratio. Were you running a lot of timing?

Sorry about that. That mods list was made up in anticipation of the stock ignition failing on the dyno, haha. I was all ready to buy a new ignition setup, but no need....yet. As for timing, we were being really conservative with the timing until we got the boost and a/f where we wanted. There is a LOT of room to go with the timing maps. Actually, let me stop saying "we". Brad Brooks is a close friend of mine and knows the AEM very well and did ALL the tuning. All the power I made last year on the AFC/2G MAS was ALL ME baybee!!

Great numbers man. I'm also curious to see what kind of timing you are running. Also, what type of race gas were you using? Have any EMS logs that you'd like to share ?

I was running C16 on the dyno. That damn VP Import shit was too $$$. As for the EMS logs......not a chance.

How much is VP Import anyway? I don't feel like calling dealers if I'm not buying.

Crower rods and Ross pistons.

sorry, meant forged, do not want to sound like an ass. Yes, 2.4 is the junk man, my winter porject for sure.

 

[TurboSpoolinIns]

Nice numbers. Theres a few of us who hope for similar results.

C16 is one of the most expensive VP has... wtf is in there import mix that makes it so much more $$$.

C16 is the way to go anyways.

Unless you want some of there really high octance stuff like the AIR RACE mix.

VP import is higher octane than C16... 120+ or so I believe. More than any of us will need

Harold/CursedGSX, how "ported" is your head? heavily or mild?

Very mild port job on the head. The head was pretty much just cleaned up. I slapped in some cams, springs/retainers and done.

This is what baffles me... so many dsmer's spend anywhere from 2-3k on a built head but we really dont need it

I guess this dyno proves that mounting a wastegate off of one of the runners still works at high HP =)

Actually, that is the HKS T4 Manifold and the gate comes from underneath in the collector area. A 90 degree bend was used to route the gate out to the side of the manifold because it was pretty tight underneath. The wastegate flange IS welded to the #1 runner, however, that is only for support. The gate still draws from the collector. The fabrication work was done by Howard Anderson of AR Fabrication in Winchester, Va. He does great work and I'd recommend him to anyone. Here are a bunch of pre/post ceramic coating pics of the fab work and other stuff:

Never seen a manifold setup like that, looks pretty sweet
