Ha-ha!!!! Make some small reserch and found that ... Clio 197 has 75°C thermostat!!! It is same dimensions and fit Clio 172 very good. P/n is 8200772994. Aftermarket are: Vernet 6047.75/J and Gates TH45975G1 - both are 75°C too and 2-3 times cheaper ther Renault "original" :)

It is never low then 90 degree - it is really more ... I have AIM MXL Pista dash with thelemetry to check this ... The summers are very hot there - and as before I simply remove the thermostat at all at the end of May and and return it back at the beginning of September.

8000rpm

ECU is ABIT Corvet - made in Russia, very popular here ... One more add-on: 75°C racing thermostat (the standard one is 90°C):

Come to London to get a new Racing Exhaust Manifold:

I come here for 2 days to some IT-conference ... well, really I come here to pickup exhaust and 182 Cup hubs, but do not tell this to my boss :) I will stay at St Martins Lane https://www.morganshotelgroup.com/originals/originals-st-martins-lane-london

Black - 175 bhp Green - 197bhp The scans are low-res, and I do not have all files with me (I just arrive from Moscow to London and are still in Costa cafe in Heathrow airport now :) ). I think there are more info in my project thread here...

This week I am gonna to install the Pure Motorsport's Racing Exhaust Manifold ( http://www.pure-motorsport.co.uk/details.php?itemid=183 ) - I will post back to back results ...

Black is almost standard - with custom 4-2-1 exhaust and decat, Samco Induction kit, matched inlet, Hank's RS Tuner remap. Green - with aftermarket ECU, CNC-mashined cylinder head, and some other tips - but with OEM cams and inlet.

This is with programmable aftermarket ECU. An I have 5 or 6 same dyno graphs ... Please look at:

New engine look:

My choise is 30/65 (for cirquit racing aka timeattack).

No it is almost 200bhp - on standard cams and inlet manifold!!!

Yes ;)

Tandem with two master cylinders with brake bias proportioning. Vacuum brake booster is removed, as well as ABS and ESP. Hydraulic handbrake. And yes, this is race-only car ;)

Wilwood calipers have two opposite pistons, so they brake better then standard. And they are very light - this is important for race car!!! Front calipers are Wilwood 4-pot:

Do you mean Rear Axle? It is by Pure Motorsport: Rear Axle Stiffening Profile Kit http://www.pure-motorsport.co.uk/details.php?itemid=153 Rear Axle Bearing Conversion Kit http://www.pure-motorsport.co.uk/details.php?itemid=120 The calipers are Wilwood Dynapro Single p/n 120-9689...

Done now:

New rear brakes - with Wilwood 2-pot calipers.

Current injectors are Magneti Marelli IWP042 - 240cc (at 3bar, up to 310cc at 5 bar). You can try MM IWP043 - they are 330cc at 3 bar/up to 426cc at 5 bar (4-hole conical spray pattern) - i think this is OK with some small airflow tuning like porting, induction kit even without remap. Megane...

Others are by Vibra Technology (you can see them at K-Tec Racing), while I have some ideas how to make my own too... For engine build my advice is: - ARP head studs - Athena Racing head gasket (very good - multilayer, exact 0.83 bore, 0.85 thikness) - Kent Cams Competition Cam Belt (high temp...

Re engine mounts: This is my dogbone replacement:

I got this clutch from DemonTweaks and they spend near 3 months in communications with the Helix (manufacturer) to build the proper configuration with the release bearing compatible with original 172's gearbox. I think that now you can get it much faster - just ask the John Harris...
