I,m just about to hit my visa card. Im buying a Janspeed 4-2-1manifold and flexi pipe as per exige, cat pipe and supersport system plus an ITG induction system and a 160 trophy tb. Its gonna set me back about 1030 quid. Before I press the button is it worth while using the 4-2-1 manifiold, is there a benefit over my S1 111S manifold. What benefits can I hope for in performance. Can anyone better 1030 for the lot?

David - I think the manifolds can wear out as standard - ie get some cracks etc so a replacement is not a bad idea
I think the set up you are describing should see you into the 160 bhp bracket - without the manifold I don't think you will quite be there.
This is about the best combo for the 111s I can think of - unless you take the head off and use a reprofiled exhaust cam (ala dave andrews)
as ever with the 111s its the ecu that's the problem so the induction and exhaust changes should make a big impact.
lightened flywheel - light alloys and ali brake discs will all help as will reduce spun weight.
Get a rolling road after and post your results ... good luck.
BTW price sounds ok.

Asfaik - there is no replacement ecu for the 111s the normal emerald route cant' make use of the vvc gear.
There was some talk about writing a new ecu for it - but I don't think it ever happened. Therefore all you can do is junk the vvc gear and start over (not worth it in my opinion)

David,
The upgrades u will install will impove on torque and hp. The HP wil become about 160/165 and tirque around 190Nm. But the ITG airfilter is way to expenive, maybe think about an Hurrican airfilter....
Much cheaper and works better
check
www.elise-shop.nl
Example the ITG costs £289 (ex VAT)which is approx. 500 euros....
and the hurricane 206 euros.
So u save money much money
Please check the elise-shop.nl website. Im sure it will save u money..
For me info pleaze contact the elise shop. I'm 100% it will save u money

Ive got the ITG, Magnex exhaust, and Janspeed sports cat on my std car - it made 137bhp/136ft/lb recently. Whilst we were there my friend who has a 111s with exhaust/induction/cat etc tried a 'before and after' run with the 160TB ...total gain 0.5-1bhp across the range...not really worth it unless you have a plastic throttle body at present and just want to upgrade to ally to overcome the 'sticky throttle' problem
Bogie
sounds like the 160 not set correctly are you sure the throttle was fully opening on reset....
agree its a low figure - but should have been more than 1bhp.
As to which way to go
ITG looks nicer and is lighter (but not much)
I used racespeed gear which was fine
so thats not much help really
Your money your choice !

Th ITG is maybe lighter but how much???
1/2 pound?? yeahh, so thats no reason 2 buy it
And the looks....?? looks better??? thats your opinion, not going to argue about that. But i think the hurricane works better and that's what u want, dont you? . And it will save u some $$$$
But its your choice, i would fit an hurricane airfilter, 160 TB, EBD exhaust manifold, sportsexhaust and a flexcatpipe.
On the www.elise-shop.nl you can find the EBD exhaust manifold. Just compare prices and mix both parts.

let me tell you what i,ve got
janspeed 340/exige manifold
flexi down pipe
motobuild silenced cat
janspeed supersports ss box
160 tb
i've modified the air box as per raceline version and sports filter.
i fitted the tb 1st, instant difference
i mod'd airbox 2nd again instant improvment.
system gets fitted this weekend. cant wait.....then r/r to check the horses etc.
lots planned for the future inc
headwork
dth
programeable ecu. i,m told ready for market next year
suspension and brakes. i own S1 111S
i,ve just order diffuser and motorsport front splitter.
fancy exige type rear areofoil.
lots of money gone, still cant take it with ya.

If you think it sounds good now - stick the ITG filter on - re what CCC said about mine - while following Mark down the A5 I could not hear the engine on the 111S - it sounds great.
As for the Hurricane working better I have not seen any figures for it - But the figures for the ITG one are on Power Train Performances website.

It was definately set up properly (Emerald rolling road, set-up by Dave Walker) the 1bhp gain wasnt a surprise, 2 other cars with the 160TB were tested before/after previously and best gain was 2bhp and 3ft/lb torque. Makes more of a difference to throttle pedal 'feel' due to more throttle being opened for less travel therefore giving the impression that the car is quicker. Std S1 with exhaust/cat/induction/manifold were getting around 135bhp/136 ft/lb. My S2 with cat/exhaust/ITG made 137bhp,with 136 ft/lb. I have the full spreadsheet with all results on it if anyones interested.
The ITG and Hurricane seem to have the same effect - about 3-4bhp, exhausts vary from 2-5bhp and removing the cat or fitting a sports cat about 2-4bhp. Seen a new S2 with Janspeed make 137bhp - just goes to show the variation in engine/car leaving the factory :-) S2 with the above + Piper cams and mild port n polish making 150bhp. All the above done on the same rolling road.
cheers

The interesting thing is the bhp increase per pound spent . . .
A cam change (Piper BP270s) is about 390 quid, on an otherwise stock engine probably gives you 135-140 bhp . . .
Whereas all this air filter/exhaust stuff costs much more for much less . . .
All excluding labour which IMHO would be not dissimilar . . .
This week I receive a set of BP270s . . . should be interesting . . .

Who is doing the programmable ECU, Emerald? Having just had my 111S TT'd along with changes across the board to the exhaust/brakes/gear changing. Spoke to TT about how to induce, ideally, more torque, via the ECU. As no one, as far as I am aware, provides an after market ECU for the 111S I woudl be interested as it provides more options for the future.
One of the reasons that the TB 160 does not work with the TT 215bhp conversion is that it flattens the torque in the mid range.
Will also consider the solid cams in the future, but for the moment with the Janspeed 421 manifold/single box, she sounds and goes (subject to running in) great.
