Great stuff.

All these things I should be able to do at work which is great. It's nice having access to a lathe, milling machine and all the parts, materials and tools you could ever need. Not to mention a willing machinist who's really into cars and motorbikes  s;) ;) s;)

Thanks guys.

Streetwerks use Bronzed Aluminium for the butterfly, as I believe it's a touch stronger than regular bronze/brass.

Yeah I just had a look at their Facebook page. The more I think about it, the more I'm asking myself is it worth it on an otherwise fairly standard 1zz. Do you think it would make a great difference to throttle response times? I'm guessing even with a induction kit that it wouldn't make much if any power, but more smooth out the power curve/delivery.

Probably not worth it on a largely standard 1zz, you'd be better off addressing the other restrictions in the system i.e free-flow intake/exhaust. But even then you won't get noticeable power gains, maybe a bit more throttle response as you say, and make a slightly better noise. In my opinion if you're serious about getting noticeable power gains from a 1zz then I'd start with the above and then look at a map-able ECU to get the most out of any other mods installed. End of the day there's no cheap/easy option for releasing more power from a 1zz (I know this from first-hand experience   s:lol: :lol: s:lol:  )

You're probably right. For now, shnazzle's intake will be enough to keep me grinning i'm sure.

Haha! Now that seems like a modification worth doing.

15bhp for £12!?

Combined with one of these which I found out about this morning:  m http://www.ebay.com/itm/2-5-INTAKE-SUPE ... NX&vxp=mtr m

Looks like I've been doing this engine modification thing wrong the whole time!!

These have been doing the rounds for ages.
Tbh good luck to them. Anyone stupid enough to go for it i dont want to be sharing the roads with.

Doesn't seem a worse hack than 'caps maf riser mod', and cheaper - what don't you like Scotte?

Ouch! At least the maf riser mod actually has some empirical evidence backing it up.

I only mean the air intake temp piggy back. Might get one.
I'll let you all know when I'm on the road with it [emoji3]
God knows what that fan thing is doing.

Ok, now I've read the feedback, might not bother [emoji20]

Picking this up again based on some FB comments.

I think it's definitely a worthwhile mod, and although I underplay mine (albeit it's a Maxbore and not Streetwerks) it certainly had made the throttle response instant and the noise absolutely magnificent.
The Hurricane intake takes credit for a lot of that, but comparing to Stewart@Boro's car with the same map on emanage piggyback and same intake, it does definitely flow better. You can hear it suck air a lot more.

Is it worth it on a stock setup? Probably not. You'll get benefits but probably not worth the outlay vs spending it on other things first (bracing, deposit on tyres, bushing, intake, manifold, etc).

Once you get a freer flowing intake and exhaust and perhaps a piggyback or standalone ecu, it's definitely a next logical step.

Probably would benefit 2zz converts more than 1zz.
