Installed the raby under-drive pulley

[RandallNeighbour]

Can someone post pix or a diagram of the underdrive pulley? It's like reading gibberish because I really don't know what this is or where it's located on my motor, but I'm liking the whole idea of more torque and HP for $150!!!

Not to speak for Jake. I just called thier shop and ordered it, sent in a check and 2 days later it was at my door.
Dont forgret the new belt. He has those as well.
New bolt from pelcan parts.

For randall, here is a picture

hey Randall -

Here's a nice write up in the DIY section

Underdrive Pulley Install Guide

[Jake Raby]

Honestly I haven't finished all of my test work with it.. I'd like to continue gathering cold weather data with it through March before we start selling them. I also need to do an install DVD to ensure we don't end up having to support every install and that people don't make mistakes.

I did A LOT of work to jhandy's car back in the summer and knew he'd provide more information for the program, so I felt safe selling him one now.

I have a whole new site ready to upload after the engine class I am instructing next week is over, two dozen new product offerings and more details on other services.
We've been too busy developing to sell.... Thats my main objective; development.

Spring would be perfect...my Box usually doesn't come out of hibernation until late April or early May. I'm putting this at the top of the list!

[Jake Raby]

I have 3 in stock and consider them proven well enough to sell.. The cost is 275.00 with the shorter belt included, plus shipping.

Email info@flat6innovations.com and Dean will get one shipped out to you.

I installed a light weight under drive pulley on my vehicle as well; albeit another brand. Unfortunately, at the time Jake's product was still under development. Nevertheless, I concur with his recommendation that its one of the best "bangs for the buck" a person can do to increase the performance of their vehicle. Go for it !

how has this missed my attention? i was thinking "nah, can't be /that/ pulley" but look at that.

Thank you, I thought about this at first but I was afraid that I would snap the boss off of the case and be totally up the creek.


Take care.

Just ordered the Flat6 under speed pulley.
Can anyone help with the part number (or where I can find the part number) for the new crank bolt I must order from my OPC - its a 3 hour round trip and I don't want to get there and find I've ordered the wrong part....

[Steve Tinker]

Many thanks for your prompt reply jh.
I'll get onto my OPC today and order, though I bet its more than US$3-50 - more like $350 here in Oz...
Did anyone use Loctite 243 thread locker on the bolt, or just tighten as per the Bentleys manual?

[jhandy]

it has green thread locker already on the bolt. like the caliper bolts.

[Steve Tinker]

That's great - thanks again jh. I suppose the OPC will want extra for that too........

We'll keep that in mind if anyone wants to convert a Boxster to Diesel...

Chinese Spammers- WOW.

[landrovered]

Well if we could put the Audi R-10 or R-15 Le Mans TDI in a Boxster I would go for that!

[Gary H]

LOL!


Just ordered mine so fingers crossed will be able to report back in a week or so.
First one in the UK?

[Gary H]

Fitted. Fairly straightforward as my local specialist had a tool to crank off the old pulley. Start to finish, less than 2 hrs with breaks and my limited ability

First reactions? Took it down the road and on to a Motorway and planted my right foot. Initial reaction...wasn't impressed. Didn't get the 'fizzy' quick response I was expecting...but then looked at speedo: 120!! OMG!

The net result is a smoother quicker car and it's definitely noticeable, so as a bang-for-buck upgrade, I'm very pleased.

I'm concerned with noise levels because I track my car, so this, a smoother air intake tract and a custom re-flash will be all I'll be doing from a power perspective.

Get one!

Can someone with the flat6innovations underdrive pulley tell me what belt they used??
