s14 intake plenum for stroker sr

[hashim]

Guys, I need some advice...... i have a sr20det stroker motor currently making 495rwhp, I am on stock intake manifold though and up top on the dyno the power falls off above 6500 rpms, I am looking into a xcessive intake plenum that uses a surge tank on the top half and then they weld velocity stacks to the lower and bolt the two pieces together, have any of you all had good experience with this manifold? i want to upgrade but i dont feel like dropping a grand on a greddy one piece. the xcessive is around 500 for everything. please advise.... here is my setup:

Motor specs as follows

91X90 bore
full race twin scroll/hx40 turbo/12cm housing
stock match ported intake manifold
ported polished head/stock valves
tomei 270 cams/bc springs and retainers w/dual guide conversion
850cc injectors/aeromotive pump and regulator
aem ecu

Go with the excessive.

GReddy are not worth it. At all. They are $300 manifolds with a $900 price tag.

The velocity stacks create cooler, smoother air into your cylinders. Very good manifold.
