Title: JPM Vents Post by: leec on January 31, 2016, 22:35:01 pm Hi guys,
I am looking for a bit of advice before I ordered a set of these. I currently run 40mm vents in my IDA's. Does that mean I order 40's in the jpm style or is there more to it than that?

Recommend using the JPM stacks as well.
JPM's flow more, so you could possibly go down a size to 38 mm, depending on driving application. Title: Re: JPM Vents Post by: modnrod on February 01, 2016, 22:23:43 pm Please, please, please Mr JPM, can you make some annular venturis for IDFs as well?
Like a set of 34mm annulars to go into a 40IDF? Yes, little tiny engine stuff. :) Edit PS: I forgot, lots of small holes, I would like a really fine droplet size please. ;) Title: Re: JPM Vents Post by: Torben Alstrup on February 20, 2016, 13:40:18 pm Please, please, please Mr JPM, can you make some annular venturis for IDFs as well? Johanjnes already did those. Not sure if they arte a shelf item though.Like a set of 34mm annulars to go into a 40IDF?

I have a 2165cc with FK 87, 044 heads with 42x37 valves fully ported and was dynoed at 185 bhp and was wondering whether it is worth the investment.

I sent him an email asking about them but got no reply, so thought he was just busy. Maybe I will ring instead and hope to get in touch.

Thanks Title: Re: JPM Vents Post by: modnrod on February 23, 2016, 12:58:34 pm I heard from Johannes today (thank you!) via email, but unfortunately he doesn't have the time spare to get the IDF version up for sale.........yet. They are planned for the future.
