Recieved, cheers matey

[Taylor325i]

Fitted mine earlier in the week. There is definately a noticeable improvement above 3500 rpm. Very slight loss lower down but hardly noticeable. A definate worthwhile mod for those of you still unsure and a bargain at the price.
Cheers Alex.

[tomislav]

Yeah this group buy is done for the time being according to a previous post.

To do with family and work commitments i think.

Thanks for all the hard work done on my TB, looks the nuts

[FMH]

I sold the 9th (8 in stock) 64mm butterfly for £20 posted, to someone who was able to machine his own 64mm body, but couldn't do the butterfly or more likely thought £20 was a lot less hassle than doing it himself, which it definitely was having done it myself!

Ps) I'm quite happy to sell the 64mm butterflies I have in stock for £20 each posted, they are the expensive part of doing a one off as fixtures have to be made. Just getting the body bored out as a one should be fairly reasonable, although you would expect to pay more than I was charging.

[FMH]

I'l have the a set of butterflies. Can i have your phone number and paypal address please?

[timmy1701]

Has anyone done a before and after on a dyno yet?

15% more airflow sounds fine and all, but what does it really do?

[E30_Crazy]

FMH:

Are you wanting them all? Was looking to get one also, if you don't get all of them. If you do, however, are you selling them or maybe even building whole BBTB's to sell??

I'm looking to get a few as i have 4 e30s. If its an easy job i will fit them, if not i will sell them at the price i paid for them.

[E30_Crazy]

sweet. well, let me know if it comes down to you selling extras. might have someone who can do the bore, then I can fit the butterfly myself.

[e301988325i]

Update, FMH is having 1 butterfly for a trial, E30_Crazy PM me if you want one too.

6 left, payment received from E30_ Crazy and FMH

Apologies guys, they'll be in the post today.

LOL, unless they owe you they'll regret doing it for free!

[e301988325i]

3 x 64mm butterflies remaining.

[e301988325i]

That's it all gone.

[E30_Crazy]

Getting my TB tore apart to get it bored out, and have some questions....

The "+4mm" is the diameter, correct? 2mm out of the sidewall all way around?

Also, looking at the butterfly I bought and the one I took out, they don't seem to match around the edges (at some points the bigger one has more between the edge of the smaller one)

Another, the screws that I took out to get the butterfly out had a sort of hat-type rivet opposite the screw head. Do I need to find new ones and have them flattened, or can I reuse them being straight through?

[e301988325i]

You have PM

[SHAZ1]

Are these still being done?

Thank You
