EFI Parts 1000bhp F4rt Renault 5

[Jack-C]

Chris at EFI Parts ever so close to a 1000bhp F4r but had to stop due to blowing a boost pipe off at 55 psi.

f**k me sideways!!! Mental machine

Spec? That's insane

 

[Gus]

Holy s**t! that is incredible.

Is that a drain pipe sticking out of the engine bay lol

 

[bloke]

had to stop due to snot everywhere ?

 

[Matt Cup]

Any videos of the run?

 

[m&l172ph1]

Drooled all over it when i was there.

Must say Chris is a top bloke that knows his stuff!

 

[leedsboy]

Think everybody who goes to EFI gets a photo of it in the corner, me included.

 

[mossyv6]

Awesome!!!

 

[MorroN]

When I went he told me how he first started out with it doing runs down the M62 at 3am mapping the engine ^^

 

[Waitey]

Looks like a VAG gearbox?

 

[bloke]

Looks like a VAG gearbox?

Yup.

 

[JamesBryan]

Has it been block filled do you know @bloke

 

[neil a]

Serious spec and power , love how it looks as well.

Does anyone know what the cam belt cover section is off , the bit that normally has the upper engine mount on it ?

 

[Christopher]

F*ck me.

 

[Crayola]

Needs some PFI dyno sauce for that missing 4bhp

Must be interesting getting that down on anything but bone dry, hot tarmac... lol

I wonder if brent has ever driven or seen a renault hatch?

 

[Daz...]

Mental, nice to see something different producing crazy power!

Very much doubt it

They'd only pronounce it horribly wrong[emoji23]

yup. was nattering to him about it today while i was there.

Is he still on the VP fuel or methanol now?

 

[bloke]

meth.

 

[JamesBryan]

meth.

I'm sure he knows, but get him to run some unleaded through afterwards. Meth is corrosive and will eat the head.

 

[Silent_Scone]

You wouldn't think it possible, would you. That's insane.

 

[George@RTR_Parts]

Some build that!

 

[Ian_182]

Bloody hell how does that get the power down.

 

[JamesBryan]

It's not a road car, purpose built for drag.

Will still spin up even with slicks though.

 

[Crayola]

8psi slicks and a limiter bash in a puddle is the only way to get any sort of power to tarmac[emoji23]

Should be an 8 second car when it's finished, easily 9 second anyway.

 

[Gt Lad]

I want

Yup I'd agree it's probably take me 8 to 9 seconds to kill myself in that

863hp at 44psi
996hp at 55psi

M1 Methanol fuel, which runs at about a 4:1 ratio whereas Petrol would be 12:1. Technically Petrol has a higher energy density per unit consumed but you can burn three times more Meth per power stroke, so even though Meth is just over half the energy output of petrol, because you burn three times more of it you get ~60% more power per power stroke.

(Direct quote from Chris on spec)
This latest iteration consists of a Clio 172 engine block and a Clio 200 cylinder head. Everything is worked of course. In a nutshell: Concrete filled engine block (no water), my own design 20mm thick girdle plate/main cap brace, I-beam rods, forged pistons, dry deck cylinder head, electric water pump for the head only, solid lifters, custom cams. VVT blank, 2x 2200cc injectors per cylinder, GTX4202 turbo @ 55psi and running on methanol.

I think he's about 400hp ahead of any other F4R i've ever seen (although granted this has limited application!), and fact the next most powerful 5 i've seen in the last 2 decades is Robbie Byrnes 1.8L F7R (Clio valver lump) at a smidge over 600hp. The most power I ever saw out of a 5 with the original pushrod 1.4 though was still Glenns >400hp lump (also tuned by Chris @ EFI)

Crazy power that is!

Also it has a dramatic cooling effect on the intake charge, so the engine requires much less or even no cooling, and the octane rating is higher IIRC

Man, it's a shame this needs to be concrete filled. I know it's not ideal anyway, but would be ace to be able to drive it on the road

 

[DaveL485]

I can only imagine how totally hideous it would be to drive in traffic, not to mention the law suits from the people it's just gassed with toxic fumes!

Can't beat a bit of methanol fumes in the morning.

Brings a tear to the eye ?

 

[Cookson]

f**king concrete filled block???? WUT?

Common for drag racing. It’s not running long enough to overheat so the strength advantage is worth it. Helped by cool-burning Methanol too.
