I collected the engine yesterday - this should be fun.

 

[DaveL485]

That inlet is fucking ridiculous.

 

[Mark Davis]

That inlet is fucking ridiculous.

Utterly bonkers - right up street

 

[Brigsy]

Throttle body looks fucking huge. Love it

 

[Mark Davis]

It’s pretty bad ass, 90mm.

I’ve been through the rest of the bits - makes my current build look shit in comparison.

Proper peripheral port housings, all resurfaced.



Lightened, balanced and clearanced rotors for 11 to 12k rpm.


Solid dowels, 5 x 1/2 studs, 11 x 10mm studs with ARP bolts to stop the block twisting.


Fully balanced e-shaft with automatic rear counterweight - balanced in conjunction with rotors.


External oil port mod.


Bonkers 4 barrel inlet with 90mm TB. 2 x rails capable of 8 injectors.


It’s needs a professional clean, I need to buy gaskets, side seals, corner seals etc. Going to need a new clutch/fly and more than likely a bigger turbo, or modify mine. Also need some porting on the plates/exhaust port.

 

[Steve Swan]

Awesome. I think a wholesalers for Bucher equipment could sell you a sort of chain mail blanket to wrap it in, like a top fuel dragster. It stops the bits flying for miles!!!!!
It will be fun........

I read every single word of that as BRAP.

 

[andybond]

Are you going to be changing the turbo to suit the triple rotor?

 

[Mark Davis]

I think so, well at the very least making my compressor wheel bigger as I already have a decent size turbine flow - around 1.25 to 1.35 AR. Generally speaking with a semi pp the bigger hot side the better.

I’ve been tempted by those very sexy looking G42-1250s but they are lots of cash. Maybe one day.

I’ve been researching semi PPs and with the right turbo can do over 1000hp. The reality is a genuine 600 will be plenty, I imagine gearbox issues are around the corner even at this level.

 

[Mark Davis]

Turns out the fuel filter was causing the fuel pressure issue. Fresh OE filter and job done, I did waste £200 on a new pump which pissed me off but what you going to do.

Pull nice now at 1bar but still limited to 7000rpm, I’ve sent logs to tuner with the hope he can up rpm to 8500.

Semi PP engine will be with engine builder over the next week or two. Hopefully built before Christmas.

Kin ell Mark, I knew you had a few issues, but feck me.

Fair play for keeping with it, I remember doing the same with the Evo all those years ago but it does (or atleast did for me anyway) finally pay off.

Problem is, once it made the power and stayed alive, I got bored quickly.

These cars have a tendency to keep you attached hahah ! Truly a love hate thing.

Not a problem Mark seems to have, to be honest

Harsh but fair it seems

It’s been alive for almost a month now, won’t be long before the next disaster

Going by the rest of the thread, that seems to mean, you only have around 6 weeks left then.

You best hurry that engine builder up, atleast now you can get them built and turned around ready to fit when the current one fails, for less downtime.

 

[Mark Davis]

So things have escalated slightly. Just bought a Syvecs S8, going to get rid of the Link. Syvecs with new loom means I can get the Aussie tuner genius to sort proper knock and WMI strategies.

The new semi pp engine will be ready quicker than I thought, likely end of Oct, will share some pictures as it gets built. The plan is a large street port semi PP with some extra bells and whistles here and there.

I’m also going to change the exhaust manifold so I can run a G45 1350, manifold needs to be moved forward a tad for it to fit.

Oh and sorry to say, I know it’s a Renault page but I’m selling the 5 to fund all this craziness. Sorry

Understandable. Big cash being dropped on this now!

Cannot wait to hear it !
