As title, does anyone run a inlet spacer with a Hart inlet on their 3dr cossy?
Wondering whether to fit it as I have a 10mm one hanging up in the workshop! Cheers Jonno.

 

what kinda power you planning on running to need the spacer?

 

450- 500 bhp hopefully Jamie.

 

I pretty sure Rod ran a spacer on his Hart inlet, but I really don't think you'll need to.
I'm running 590bhp on mine Hart inlet without a spacer, you'll have to ask the experts to see if fitting a spacer at lower power would be benefical in anyway.

Thanks for the info mate.

 

For out and out power, there may be a tiny gain to be had but not much if any at your power level, but you will destroy your throttle response.

 

Below 600bhp the spacer will not be required the Hart is a fine inlet without it.

 

I know 2 people running 700 using a hart with no spacer.

 

You don't need it mate

 

yes no need the spacer the hart is easy to go 600+ withous spacer .is enough air .but if you put on t34 garrett turbo engine a hart you will earn in big lag .better the normal inlet for t34

 

I agree, if you want to install a Hart inlet manifold on a Stage 3 engine with a T34 you must have installed a more aggressive inlet camshaft (like a BD14 or an AB07) to give more torque in mid range rpm because the hart inlet has more space of air storage inside and as result creates lag, from 4000 rpm and up to rev limiter produces more power than normal 2wd/4wd items.

When you install this inlet manifold you will need to live map your ECU
