Modded zetec head flow chart
Shooter63 - 16/4/15 at 09:18 PM

This is a question for all you guys that run zetec engines with a modded head, would it be possible for you to post the flow charts that came with your head or a chart that made you decide to go with the company that did your head ( presuming that you wouldn't buy a head without seeing one)
I'm thinking of upgrading and would like to know what company to go for etc.

I went with dunnell due to results of other engine they did along with confidence in them when visiting and there help.

I considered raceline,scholars and cnc heads.

Paul from dunnell was 3.3 bhp out in his guide to what we would make to my favour and even he was suppressed and pleased with the torque produced and he put that down to the simpson exhaust primary's going 4-2-1.

Would recommend then with out hesitation.

I've got a Dunnell option 6 kit in my car. Ran it for the 1st time last weekend. No power figures yet as it's not been rolling roaded, however I echo the above comment that Paul is a pleasure to deal with.
