Hi guys,
Was wondering if you clever peole could could help me with a safe location for my BOV. I bought an MX5 with Turbo Greddy already fitted with an HKS piggy back ECU with a 5th injector. (the 5th injector is mounted in the cross over pipe from Turbo outlet to inlet manifold).

I am going to use it for a track day toy and so am fitting an oil cooler, intercooler and getting it properly set up on the rolling road to hopefully make it as robust as possible. I would also like to fit a BOV probably a twin piston type to atmos or a recirculating type. My 5th injector is getting mounted close to the inlet manifold and throttle body, but really the BOV should be mounted in same area, but my concern is that when the BOV realeases it will dischage the pressured air and fuel (which has been injected on the fifth inj) and so all it needs is an ignition source (anything with an internal combustion engine, especially a red hot turbo) and BANG, not what I want.

I could mount the BOV just after the turbo but would probably have the same problem, If I use a recirc typ then I'm putting fuel and air into the suction of a red hot turbo.

Is my theory correct or not, your help and thoughts would be welcomed.

I have no idea, but I'm in for the answer.

I would guess that if you VTA (or recirc, shouldn't matter) just after the turbo, and have the 5th injector just before the throttle, you won't have any fuel come back out the BOV.

Your BOV doesnt have to be by the TB. You can mount it right on the intercooler if you want.



Besides, I don't think you'll have as big a problem as you think. The HKS controller works off MAP not airflow so as soon as the throttle plate closes, fuel stops flowing.
