Mantis Manometer

Post by wattsmonkey » Thu Aug 10, 2017 4:21 pm

I bought one! Dean absolutely lovely to deal with. Had to wait an age for UK customs to let me get my hands on it, currently in garage with pipes detangled and draining back into reservoir.

Will report findings.

Cool!

I need to get around to borrowing one.

I have a feeling my TBs have never been balanced.

Cheers

Well, like it says on just about every post on MyE28 and elsewhere, this makes a marked difference to the running of the car. I had to arse about resetting the base idle speed, but I am extremely pleased with the results; so much so that I'll post a few videos once I've sorted out a way of doing that! I've been meaning to post a recording of the exhaust sound too.

Yeah, I'm afraid I bottled it :oops:

I've got all the bits - hose, barbed connectors, securing nuts - but didn't get my head around what to use for the reservoir. Having seen the mantis one in the flesh I have a few ideas now.

I got one of these too. Mind blowing difference in throttle response after doing the full adjustment.

He even sends a set of printed out and laminated directions so you dont have to worry about gunking them all up over time.

Definitely do the dial to the TB adjustment as well. You can get nice and even results to an extent with just the fine screw adjustment, but it was night and day once I took off the plenum and adjusted the TBs directly to match before using the fine adjustment screws to even out.
