Ph1 172 Track Car. Next Year I Go Racing - Hopefully!
No it's rubber stainless braided to the pump, ptfe wouldn't clamp to the pump outlets.
It change's to ptfe once inside the car.
These race cars don't half get expensive don't they!

Yep.
Big Update Time
Ok I thought it was about time I let the squirrel out of the bag.
As everyone in class A seems to be doing lots of mods and chasing power I needed to decide what to do myself or I was just going to get left behind.
I really wanted to keep the engine standard like last year and continue my ethos of low cost enjoyable racing. But if I was going to be the only car in class A running a standard engine I don’t think it would have been enjoyable.
So I needed to think of a plan. Everyone else seemed to be going down the forged engine, cammed, itb’s route. This is really expensive and I just couldn’t justify the cost. Also if something goes wrong it would mean an expensive rebuild every time.
So I checked the regs and also put an email in to Steve to double check it was ok and in stepped this, a rotrex C30-94.
A low boost (very low boost actually) Rotrex supercharger conversion. This was a cheaper way to go for me than building a high spec forged engine. Also my whole philosophy behind it was I wanted to keep a standard engine. I know some people may say ooh running a standard engine with a charger is asking for trouble, and they may be right. But it’s a very low boost kit and if the engine does go pop I can just source a second-hand one for £200 and swap it over in a weekend!
Obviously I have renewed a few parts along the way as well.
New Renault tensioner. New water pump. Megane keywayed crank pulley. Megane injectors and plugs. New cambelt kit. New dephaser. New clutch. Gen90 ecu etc, etc.
And an updated fuel supply to cope with the extra demand.
I will list the full spec later on.
Finally a trip to Chris at EFI parts was in order to get the mapping sorted.
The result was 234bhp and 190lbft torque. I could have gone for more power, but I have used a very large pulley and a restrictor to keep the boost and power nice and low.
I don’t have any lightweight fibreglass panels, also the charger an associated intercooler/pipework add a bit of weight.
I also don't have the fancy roll center correction kit. But I am hoping this will be enough to a least make me competitive.
If it all holds together that is!

Lovely! :smile: Enjoy it bud!
So, chargers are ok in Tric Trophy....
Mmmmmm. That certainly gives me something to think about.
What boost are you running out of interest?

Yeah I did think about that, might not have been a bad idea. But probably still safer with an intercooler.
Cheers mate, did all the work myself so I'm really pleased with it.
Yeah I checked it was ok and sent an email to Steve the series coordinator just to make sure :smile:
Boost is very low, about 0.5bar I think.
Ha I did wonder what you was doing when you said you wast trying something different, assumed you was going groupN timings or 197cams etc.
Are you staying in class A or moving to class G?
Great power figures, how does it drive?

Nice work James.......... but,
Cant see this in class A though, a supercharged Clio....
Class G has all the misfits
even though mine is all original!!!!!
Consider the can of worms officially opened.

Couldn't keep it to myself anymore mate :smiley:
Don't know how it drives, I haven't driven it yet! Power delivery is nice and linear though so I am expecting it to drive like a tuned na car.
Steve said it would be ok in class A, and it has similar power/torque to the big boys in class A so that's where I am staying.
Still don't have any lightweight fibreglass panels or roll center kit so not really expecting to win anything, just wanted to be competitive and have some fun.

Cheers mate, yeah I guessed it would raise a few eyebrows.
I did check it would be ok in class A, and I don't really want to move to class G. To be honest if it was destined for class G I would have turned the wick up a bit more, but I just wanted to be competitive.

I know nothing about this, and a far as I'm concerned, it is not a class A car. Forced induction!
It's just another means to achieving the same figures as 423s, high company and pms manifold.
Rather than just say it's FI so it can't be class A surely it's fairer to look at the power output and see it's the same as other class A cars.
So in that respect would it be better class the cars by bhp/tonne?

I understand what you are saying Tom but the problem is you have to be able to check eligibility for the series relatively easy so if turbo/superchargers aren't allowed its pretty easy to see if they are fitted.
If you then change that to whatever you want as long as it doesn't exceed 230bhp then you have to enforce that with dyno's etc. Nothing to stop you having switchable maps with the second map running leaner, more ignition etc. Sticking to the simple rules keeps eligibility checking costs down. No one wants to paying for a dyno to come to race meets or installing power loggers in the car like some series do.
I think the problem is a lot of guys have spent big money with the N/A route as that's what the rules said and then to undermine that by then allowing a charger seems wrong. I don't see it being a problem in the invitation class but in class A I'm surprised Steve has said yes.

Woah there hang on I'm pretty sure the regs state normal aspiration only ie no turbo or superchargers otherwise I'd be running a full house Megane turbo motor and 6 speed box!

Hmm I see what you are saying guys and kind of agree to a point, but I couldn't justify the expense of a forged build. I now have similar power but my car is heavier than most so I don't really see the issue.
I could have turned the wick up and had 260+hp but I didn't as I just wanted to be competitive and have some fun.
I was a bit surprised it would be allowed in class A myself, but I did check it out first and I will be a bit miffed if I have to now move to class G. But if that's the consensus then so be it.

In that case non-intercooled setups would stop turning the boost up on the day. So that's that dispute sorted.
And Russ, your figures are very similar to James's but you have less weight to worry about. So not only does it benefit you in terms of handling you also have more bhp and torque per tonne.

I think you took a huge risk to be honest James and Steve should know better.
I would disagree that comparing the RC hubs and added as a justification for a SC, the hubs reduce bump steer if you suffer from it and personally wouldn't say it reduces lap times otherwise.
This a sensitive subject as it was only last month we was debating the class C saxo from entering class A (due to a 0005cc overbore) not a problem as that in the regs but due to being way to fast has denied another class win from a potential original class A car.
This just proves how "lose" the regs are and how they can be interpreted (which shouldn't be the case).
Personally I'm trying another racing series in July and cutting the numbers of races entering with the TARC, before it gets too expensive.
This isn't a knock at you James at all, but at the the coordinator.

The hubs correct the roll centres which is the important bit that effects how the suspension works sonny. The bump steer correction helps to combat geometry changes through suspension deflection. It's a package that does and will reduce lap times I'm afraid.
No offence James but if your car sits in class A then I'll be racing elsewhere!
Not a dig at you but more the disregard of the regs by even the club owner. People have spent a lot of money to raise power in class A and well within the regs.
Come and race in class G and I'm sure everyone will welcome you with open arms.

Shhhhh dont tell him that
Yes I meant to say that, their great bit of kit no doubt about that, but just no justification to adjust the regs, these fall into same category as chassis development not engine (for the sale of the series regulations)

Lol! No I agree, there's no reason to adjust the regs for the hubs, as like you say it's chassis development.
Ok guys this has definitely caused a bit of drama!
I am really please with the build and have been open and honest about the results. I have also had it confirmed again in black and white again by the series coordinatior that I am fine to race in class A with a charged clio.
I was maybe a bit naive about this and didn't realise it would cause so many mixed opinions.
I have conferred with several of you by PM and taken all your opinions on board.
The outcome is I am going to voluntarily race in class G not class A, so bring on the 2015 season!

I'll be following this closely bud, as I wouldn't mind running mine a few times next season in Class G.

I think that is very noble of you James.
Steve was very naughty to even say you could run in class A, esp without even discussing it with me.
I think you may have saved a revolt by opting to go class G

There is nothing in the Tricolore regs that bars forced induction from class A is there?
An oversight for sure but seems a bit harsh on James after getting approval.

Last time I read the regs you could go from carb to injection to it's.
No clio has a forced induction, so this then becomes an invalid engine. This = invitation.
Simple.
We pushed Gordon with his mi6 engined 205 into class G because it wasn't an engine that was put in the car originally.
These things have to be nipped in the bud straight away.

Technically your wrong tony. Dci's were forced induction. Flol!

Smart arse.
I knew somebody would pick me up on that.
No clio sport had a forced induction. X
