Is it just me, or does everyone with a Full-race manifold experience more vibration than a stock S2000 through the steering wheel, gas/brake pedals, shifter?

Doubt it's the clutch, as I have an ACT pressure plate and OEM Honda disc. 46K miles on trans.

Setup is a Laskey 9:1 short block, Stage 3 ported head, FR manifold & downpipe, GT3076R turbo, AEM ECU, Walbro 255 pump, RC 1000 injectors (in case I went E85 or upgraded later to GT35 turbo).

Thoughts?

I've had my kit on my car for close to nine thousand miles now and no vibrations anywhere

 

Cracks, my last tubular manifold was shaking my car to pieces, turns out it was cracked up all over...

 

No vibrations for me .

 

Nope

 

No vibrations for me!

Let me reiterate that i have had no issues with the AUTHENTIC fullrace manifold.
Stuff thats not robotic welded im sure wont be as strong and perfect as the robotic welded ones

 

Did you guys mount a brace from the bottom turbo/downpipe bolt to the block? Mine's an authentic FR, so I'm a little concerned.

Also, is anyone using the V-band turbine housing instead of a 4-bolt turbine housing? ATP Turbo has the V-band, and after looking at how hard it is to access the top bolt, I'm considering yanking the whole manifold/turbo combo and getting a V-banded turbine housing. My top bolt (of the 4 for the downpipe/turbine junction) loosened but the other 3 were tight.

Using Allen head bolts there -- anyone using studs instead?

Thanks again,

No vibrations after a year. Is the compressor hitting the frame?

 

Compressor has ~ 0.4 inch between it and the frame when the motor is just sitting there (not running or under load). I've clearanced a hole that allows the compressor to rock to the passenger side to clear it. There's no increase of buzz based on load (which would be the case if the engine was rocking), it's purely RPM dependent and does it whether there's load, no load, coasting.

Good thought though. What kind of static clearance to you guys have on Full-race installations?

Thanks,
Stanford
