JPM Vents

[leec]

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?

I found that the OEM IDA stacks would vibrate, after the removal of the auxiliary venturi.  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.

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.

Johanjnes already did those. Not sure if they arte a shelf item though.

Does anyone know what the average increase is with both the vents and stacks fitted, I appreciate a lot will be dependant on the engine. 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.

Thanks Torben.
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.

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.
