come racing manifold

[keith reed]

The person I bought the aluminium radiator from had a vr ute fitted with turbo charged v8. It also had a comeracing inlet manifold. He said that they were not much good unless they were on a force fed motor. He had a friend who had one on a natural aspirated 355. When the motor was pulled apart they found that the 4 rear cylinders were starved of fuel. Has anyone heard of this problem? I wanted to get one for the old girl.

I know COME racing themselves don't recommend them for a N/A 5L
I've also heard stories on another forum about the leaning out on some cylinders.

COME released a second version with a slightly revised plenum (they have the domed lid). Maybe the second version has addressed the problem ?
Might be worth dropping COME an email. From what I've heard they are fairly upfront about their products.

No good on N/A engines, they are designed and built for boosted applications. If you want an aftermarket manifold go a 4 barrel one, Torque Power, Harrop and Come Racing do them. TP is $1020 plus postage then you need to get the TB and aircleaner for it.
