Hurricane and 52 mm throttle body.

[ganglandboss]

I am planning on fitting these to my Elise. It is a standard S1, except for a Magnex exhaust.

Is there anything I need to know before I do it?

Cheers,

Dave

Edit: Sorry, not Janspeed - Magnex.

The 52mm tb might be slightly less smooth from idle - it's a bit on/off because it doesn't have the softening wedge in on the butterfly that the 48mm tb has. In truth you're unlikely to notuice much difference from this mod alone, the 52mm produces around 3-4 bhp more on a vehicle modified with higher profile cams.

Don't think I've heard a hurricane, but I hear good things! Maybe buy some earplugs.

I wouldn't bother with the 52mm TB for the reasons noted above plus that you'd need to get the car remapped to get any benefit IIRC, and then you'll need hotter cams to get any worthwhile performance benefit. Just upgrade to an ally 48mm one to get rid of "sticky" throttle which can be a problem with the plastic ones.

Hurricanes sound great on the standard engines, and it'll sound good with the Janspeed.

Fitted a 52mm TB to my S2, no idle (or any other) problems, it improves throttle respone but on its own will make no noticable difference to power. On a S1 if you still have a plastic TB it is a worthwile upgrade.

Would the 52mm do any harm though? I do plan to do the cams in the future. I do want to eliminate the sticky throttle problem so I'd rather put the 52mm in now rather than change it later when I do the cams.

I have the 52mm TB and a hurricane on my S1 and it's brilliant. Apart from the Eliseparts exhaust my car is standard. No problems with idle or anything.

I've got 52mm throttle body, Hurricane, janspeed 4-2-1, and larini clubsport with cat bypass, no probs with idling, superb noise level and better torque.

As noted by others, I doubt it'll do any harm, and if you're planning on doing other stuff then probably worthwhile. If in doubt have a chat to DVA.
