Re: Skunk2 Ultra series "Street" manifold Pics
first impression of the manifold.
-The manifold came in late last week along with a 74mm skunk2 throttle body. Matching on the throttle body inlet is right on 74mm which is a plus if you are running a 74mm throttle body.
-I am running a b16 head and it needed a good bit of porting to get a good match with the head. I opted to use a hondata gasket with it being a perfect match 'out of the box' to my ported b16 head. So from looking at wishingiam pics vs his gsr head my b16 head had a heavy mismatch on the bottom of the port. So it looks like skunk2 put the manifold half way between a b16 and gsr porting wise. Additionally I opted to clean up the runners a bit as the casting is rough on the plenum side just like wishingiam's. I will post pics of this later when i swap out the manifold again for testing.
-Lastly the throttle cable bracket seemed to be sized incorrectly. If you look in the pic I ended up using a p73 bracket as that was the only way I could make it fit.
***First impression out with manifold butt dyno says I lost a little bottom end & throttle response but gained on top end and extended power band up about 1000rpm higher. Granted I change throttle body 68mm vs 74mm and this intake is short ram vs old intake cold air aem was too small diameter and would not fit with this setup as the throttle body sits lower and at different angle. When I make it to the dyno I will have other intakes lengths to test out so I can eliminate that factor. Use this information at your own discretion but this is just my first impression of the manifold. The pro series fell flat after 8500rpm where as this keeps pulling up to 9500rpm. This manifold isn't for a stock motor. You better plan on reving well into 9k range if you wanna take advantage of this manifold

Re: Skunk2 Ultra series "Street" manifold Pics
Just picked one of these manifolds up. I will post results with comparison later than sooner. It will be Ported ITR manifold VS SKunk2 Ultra Street.
PS...it will be on an N/A Motor on not a boosted application.

if this proves to be a good upgrade, there might be a reason to reconsider making bseries billet steel cams. After speaking with a few people, I think I would like to try 0.500 lift first. around 12.7mm valve lift with zero lash.
