Induction Kits

The Oily Bits S2 Specific Topics

Pesky/Steve,

I haven’t tried these systems myself. The technical guys at Lotus don’t think aftermarket filters add any power, just a different noise, which does appeal if it makes the right notes.

FWIW, when i uprated an S1 Elise to the motobuild 150 spec, the alternative K&N cone filter supplied went straight onto the intake manifold, gulping lots of hot air. I had it re-positioned down behind the LH air intake & ducted to the manifold. This dramatically improved (smoothed out) low speed/revs pick up, but didnt feel like it delivered any more power from its original position. Not a direct comparison with the above i know. Nor did i try the original filter on the rest of the motobuild kit.

If these new systems offer a ‘nicer’ noise, without being any louder than standard, I could be interested though.

Tim.

Not sure I would agree with them - a quality aftermarket filter will always be better than an original paper filter. The original filter for the S1 was a Pipercross but only after one developed by ITG was rejected - alledegedy on the grounds of cost.

i rang the lotus guys for insurance purposes… they clearly stated that pipercross induction kit + stage 2 ‘performance’ exhaust = zero power increase

to be on the safe side do you think i should tell insurance company that it adds 2-3bhp?

I’d just tell them that you have them and let them figure whether it adds anything

Ha dth Exige serviced today (1000 miles) and had a pipercross fitted. Must say it was the right thing to do. Below around 4000rpm its not that difference but as soon as you accelerate the all hell breaks lose. Then the 2nd cam hits and it bangs and turns into a screaming banshee. There is definatly more throttle response and it feels like there is more power, but that may be my immagination as I haven’t really used the 2nd cam until now…Oh and it does sound like Darth Vader when the turn the engine off …Great

welcome to the club

I’m going to buy an induction kit to compliment my Stage 2 exhaust.

I’m I correct in assuming that they all do pretty much the same job, giving the same level of induction noise and a marginal increase in power, be it ITG, Pipercross, Reverie etc. Is this the case?

Does your lev2 exhaust pass the dB limit on track days?

my pipercross is LOVELY. it goes BANG (literally) everytime the cam changes to the power profile. VERY reassuring esp on the motorway. highly recommended!!

Wich Pipercross do you have? On their site i can find some different types:
Volocity intake system for axample
