Excellent stuff !!
Cheers Nev, glad you are very happy with it
The cams had a big effect up top on Nevs Car 18 BHP up on top and huge torque in the mid-range - Where most people drive for the power, but obviously, the duration of the cam meant that low down power (2000 - 3000 RPM) was down a bit, but we were expecting this with the SMT.
The Omex Kit that I am doing is a lot more sturdy down at the bottom end of the range with the same Cams.
I have finalised the prices for the SMT Kit:
Kit One
This package offers the most cost effective means to significantly upgrade the BHP/ Torque currently available on the market, without significant engine work and or conversions. It should be considered by those looking to make power gains in the most cost effective manner. This would be an ideal kit for the individual wishing to retain the existing facilities in the car such as fly-by-wire, cruise control and speed limiter, yet looking for a large increase in power. (Expected peak power increase + 18-20 BHP)
SMT6 - Piggyback ECU retaining the standard ECU, the SMT offers the ability to map the standard fuelling to a much better level. Obviously not to the same extent as complete stand-alone engine management (OMEX as in Kit 2), but competently deals with the job of correcting the fuelling, as proven with this example.
y0z2aSport Cams - CNC Machined cams used by Championship winning teams and designed and manufactured by the world leading Camshaft Manufacturers. Oh, and you dont get any of that tapping that you get from Pipers
AWT Manifold Matching - Matching of the inlet ports to improve airflow.
Cambelt Change - Preventative maintenance as the engine is in a suitable state to have the cam belt replaced
Fitting & Setup - By Renault Specialist Grey Devil Industries (GDI)
Rolling Road test and final mapping session.
£2495 inc VAT & Fitting
Optional (extra) items on this kit is the Exhaust that we are doing (63.5mm High Flow Exhaust and Peco uprated injectors.
To save anyone saying that the figures are out, We worked on ATW BHP & Torque figures with a 32% loss (pressure was very low - it even hailed and we had a squall while we were mapping it ;-) )
Either Way the ATW figures before and After show the increase that the kit has provided. Will try and get it online over the next day or so.
/y0z
PS. This is a completely standard engine other wise.

Thats great,i bet that little car shifts
Nice to see aswell, someone putting there money where their mouth is on these conversions.I think we all know its possible to do but when you get muppets like LAD motorsport trying to put you off tunning figures and rolling roads with a £200 hotel bill for the privelige,it kind of puts you off getting it done yourself.
Well done yozza and well done nev172 for taking the plunge.

Its great to see finally some specific kit for the 172/182 producing the goods.Quote: Originally posted by y0z2a on 08 April 2005

y0z2a,
Will you publish the graphs showing std vs above kit, would be great to see it visually. Also when is the website up with individual prices as some people might just want to do it step by step and not in one go:-
Matched ports
SMT
Cams
etc.
When you have a website showing all this and graphs showing gains vs std and maybe vs the throttle body kit which it similarly priced. I have every confidence in you being sucessful, good job.
Nippy white cup
Sounds good m8. look forward to seeing the graphs and Pod times
(up from 140)

We have a whole cocktail of tuning products to go live very soon, all will be online in spreadsheets comparing power/prices and everything else - graphs videos, 0-60s & 0-100 (as close as we can get them with an AP22.
1/4 mile times are going to be down to individuals I guess (and down to driver)
an interesting thing I thought this morning, Nevs car has only got 7500 miles on it...

The thing that I dont want to do is go mental saying it will give every car +20 BHp, it depends on whats been done, but the one thing that we are sure of is that it makes a bloody big difference.
We are doing a build of an engine on the dyno to get proper figures before & after and obviously it will be possible to see the power / torque changes much better than on a RR.
That way everyone is safe in the knowledge that they know what they are buying and that it will deliver a percentage increase. We think it will be about 15% increase in power on most engines, but would like to have ROCK SOLID facts to prove it, and to be totally open and public about them.
Lets see how the Dyno goes with a full map and then we will have solid percentage to work to.

OMEX ECU is an awesome bit of kit, i have one on my throttle bodies track day VTS.
no doubt you would get better gains with an OMEX as its infinitivly adjustable and mappable.
what sort of duration is on the cams?
speaking from saxo experience here, if you go higher lift etc, do you need to go for solid lifters, pistons with valve cut outs, uprated valve springs etc? or does the clio engine not work in this way?
looks like a decent bit of kit. nice one!
All engines operate in the same manner, however the tolerances you encounter are different in all engines.
In this case, the point at which you swap to uprated single or swap to double springs depends on cam duration and primarly operating rpm and valve acceleration rates, lift has very little to do with it. The pistons already have valve recesses, but again once you start really working the cam timing will require new pistons with the correct shape and valve recess depth. And the F4R has roller radius path follolwers so the clearance is taken up on the hydraulic pivot and these are not needed to be changed unless your exceeding 8000rpm.
Yoz, it would be beneficial to do a run on a totally std engine to see what the cams alone do.

top show guys, a 200+ cup that can finally be proven!
Great Teamwork Andy, y0z and Ben. (Im sure Rupert was involved somewhere too!)
