Very impressive, nice to see something a bit different.

Just found this, you must have spent a fortune. . Great work!

Come to London to get a new Racing Exhaust Manifold:

Lol at a manifold on your hotel table

 

[prince_zorro]

That's great job dude....

What ecu you'r using?....where did u program it?

Yes, it is very good with high lift camsshafts too! Here are my most current engine spec:

Engine:
---------
JMS RS2 Inlet Manifold
CNC-machined cylinder head
CatCams (304/304° - 12.45/12.45mm) with adjustable vernier pulleys
CatCams uprated springs (single)
Supertech valves
Solid lifters
H-beam forged con rods with ARP bolts and ACL bearings
Clio 197 pistons (give 12.5:1 when installed with Clio 172 head)
Megane 225 injectors @ Jenvey steel fuel rail
ARP main and head bolts
Kent competition cam belt
Athena Racing MLS gasket
Pure Motorsport AirCon and PAS removal kit

Transmission:
-----
TTV Racing ultralight flywheel and Helix 184mm clutch
JC5-129 gearbox with Gripper LSD (30/65 ramp angle and 4.33 main gear)
Ceramic coated synchronizer rings for 3-5 gears

Very jealous

Bet this thing flies

 

[SharkyUK]

Great thread and a very nice spec!

 

[Martin.]

You came all the way here just to get the manifold?? Proper commitment but why didn't you just get it shipped? Not as if you can carry it on the plane with you to save it being damaged.

I think he was over here working... and also used the opportunity to pick up the manifold. Or the other way round.

 

[ayk2008]

ECU is ABIT Corvet - made in Russia, very popular here ...

One more add-on: 75°C racing thermostat (the standard one is 90°C):

 

[karol_SVK]

Great thread, good progress are you doing.
Really impressive manifold with a huge exhaust diameter.

Just out of interest, where do you have your rev limiter set to, how many rpms?

 

[ayk2008]

8000rpm

 

[Chip-mk1]

Why would you want to run your engine colder than 90 degrees?

 

[Chip-mk1]

Ps

the manifold will foul on the strainer on a 172 by the way it's only direct fit on a 182.

 

[ayk2008]

Why would you want to run your engine colder than 90 degrees?

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.

But if its over 90 anyway, then that means the thermostat was open anyway, so what difference will it make with a different thermostat open instead?
Surely you need a better rad if temps are proving hard to control?

 

[ayk2008]

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"

This is specific for competitions I take part in. It is "timeattack": 3-4 laps and the best one goes as result. And the "normal" temp in July is 35 degrees (in shadow).

And yes, I have good PWR Performane rad with big Spal cooler (I have two Spals: one is thin and light, but less aiflow and second is thick and heavy for July-August).

I think what I need to do first before the next season is to paint my car from Black to White

to reflect away the heat to help cool your engine? lol

 

[ayk2008]

Got new conrods for my next engine build. The top one is Woessner, standard 144mm centre-to-centre length, while the new one is "+4mm" - i.e. 148mm. And new one is for 18mm wrist pin.

 

[Ph1 Tom]

Which pistons will you be using? There's quite a few in the 83-84mm range.

 

[Chip-mk1]

Little bit more length on the rod should really help at the top of the rev range

 

[ayk2008]

Yes, and I hope to expand the torque too ...There are not only length but the weight issue - the small conrod end, wrist pin and the piston will be much lighter then now!!!

Tool Steel wrist pins - 18mm x .115" (2.9mm) walls x 2.470" (62.75mm) - weight is 63g. Will need to cut them to ~40mm length and it will be ~40g. The lightest Woessner wrist pin for standard pistons is 78g!!!

I want to make them custom. Something like this:

 

[Ph1 Tom]

Very nice, should rev well. Will you lighten the crank? 197/200 crank is 1.5kg lighter.

Not yet. The used are very rare here, in Russia - and the new one is too expensive For current setup I can easily found a used crank (or engine bottom) from any F4R engine (Megane, Scenic, Laguna) as there are a lot of such cars at the local market. But only 30-40 Clios 197/200 was sold in Russia.

And is the 197/200 crank steel or iron?

 

[NorthloopCup]

Its iron mate. I'm the person that weighed the 197 crank. I can possibly get another one if your interested? Not sure how much postage would be to Russia though! :S

 

[EVOgone]

Interested in what gains you get when fitting the new PM exhaust manifold. When you fitting and getting remapped?

I hope it will be fitted today or tomorrow as soon as we have the trackday at Sunday. The s**t is the Aeroflot lost the box with the exhaust on my way back to Moscow and they found it only yesterday. So I will be able to remap it only on the next week (the dyno doesn't work at weekends).

Wow, thank you! This will really helpful. PM you!!!

 

[ayk2008]

One more idea about the crank preparation. I do not remember where I got it, but somebody post the difference between the crank at standard Clio 197:

And Clio R.S. R3:

Any comments?

Upsss. As far as I remember - Clio 197 has different flywheel bolts mount, So I will be unable to use my Clio 172 flywheel?

Never paid any attention tbh mate. Post a pic up of the end of a 172 crank and I'll compare it to the 197.

 

[NorthloopCup]

My 197 crank looks like this one.

 

[NorthloopCup]

Just had a quick look on k-tecs website and the bolt spacing appears to be the same on a 1*2/197. 7 bolts secure it to the crank on both.

 

[Ph1 Tom]

IIRC they are the same, the only difference is the shape/size of the flywheels due to different clutches. So what you have now will fit a 197/200 crank.

 

[Fred@BTM]

All the same fitment across the F4 engines, 7 different cranks available!

Any thoughts on the differences in the cranks that are posted further up Fred?
