I noticed that his cup seemed smoother in the power delivery than mine. But when I got back into mine it seemed faster, like the engine was pushing more power out. Hard to explain, but mine feels more responsive and pulls like a train at all rpms in all gears except for 5th at 1000rpm - takes alittle more time for revs to rise. Have swapped from SUL to Optimax, after 5 tanks fulls and the difference to me is very noticeable - mpg is 36 even after thrashing car for half an hour each day to work.
Ive also been tracking this R-Sport ECU business. R-Sport in wimbledon and one outfit in the North [?] will apparently be selected by Reno to fit the upgraded ECU which is still under test currently. I spoke to R-Sports [ex Radbourne Racing] and they reckon April before they get the go ahead from reno. They say theyre also working on Reno-approved mods on the braking system further down the pipeline. If you call them (ive lost the number, but just do a search for radbourne racing and use that number), theyll add your name to the list.
The other place to look at is an outfit in France called http://www.efjies.frwww.efjies.fr that already do a reno approved ECU upgrade, they also show a graph with before/after torque and power, although I couldnt blow it up to take a good look.

take a look at the 230hp megane thread on the main board. theres another french outfit (this time just across the channel) with equally sexy stuff including a full conversion with TBs, ported head etc etc 220hp for £5k. Simon (I think) had already mentioned the link to http://www.technomap.frwww.technomap.fr . I had a look and a chat with them . downsid is they need 3 weeks, getting the car across the channel every time you need something done, etc. Unfortunately, everybody is WAY behind on 172 mods in the UK, including Hill, K-tech, BB

yes...
Not too sure about the filter though, whats the point to fit those gleaming TBs to suck in loads of hot air. Youd think that for £5k+ they would provide decent ducting from what looks like a sexy carbon fibre air box over the TB trumpets. Cant be that difficult. So, how about an expedition to Dieppe then, maybe we can negotiate a group discount ...
k-tec arent. Theyve only just sent a 172 head to janspeed for some work. TBs are not even on the radar screen. Problem in the uk is that one of the best TB manufacturers - Jenvey - havent got a manifold for the 172, as individual TBs are not the problem. The only other source I know of is Alpha Webber and they only supply through Prima, and as I said before theyre twin TBs which Im not keen on (either use a single larger TB, or do it properly with 4 individuals). Another outfit is Chadil in Belgium, and I think they also use twins. The other problem is that the mod is a bit involved, as I understand the existing "fly by wire" throttle on the cup would have to be removed and replaced by a traditional one. Id rather have everything done by one outfit who know what theyre doing vs. having my car experimented on by half a dozen garages!
