Yeah deffo will be, Cheers dude...I’ll get my graph up at the first opportunity [Smile]

Only difference i can see on specs is mine has the bigger exhaust wheel. I don’t know if the EFR range have the extended tip, I can only assume so as it’s their flagship models!

Do they have the same wheel materials?

I assume so but don’t actually know. Mine is a billet wheel. I assume the EFR is too.

How are you getting such high numbers and low boost compared to mine? [Crying or Very sad]

Congraz btw [tongue]

I'm on a 2 litres with a gen 2 3076r and i get 430 at 1.9bar with wmi
6.3ar.

I see no downside to your setup, it even spools pretty well.

There's something bothering me with this map, please dont think it a slap down but rather just asking to make sure nothing is untoward.

A mapped ct20b running circa 1.2-1.3 bar is more powerful than your 5s build up to about 6000 where the new turbo beats it.

Actually, the ct20b is ahead until over 5k. Given a 5s should spool quicker and new gen turbos there's something that just isn't right here. Is it a small exhaust housing on yours?

Seems a huge build for 1500rpm of extra gain.

Thanks for the imput [thumleft]

But I did watch it get mapped.. This build isn't finished and wasn't for max bhp it was built purely for good reliable build... The turbo does have a small housing as I wanted it keep it close to stock....

CT20b makes 270whp at 7k @1.8 bar mine makes it at 4200ish @1.4bar I can crank the turbo up to 2bar but I don't need it to spool that quick and it would kill me lol I can crank up the boost when I get brave lol

This isn't a final map just one so I get comfortable driving the car again...i will post up a 2bar graph when I feel brave [thumleft]

So a little update...

Due to real world driving ( not in a well vented dyno room) or moving I have noticed the my fuel set up get VERY hot... I thought it was heat coming up from the exhaust but after further investigation I have ruled it out!!

So I have done a few bits to try and conquer the problem

I mounted all the parts off the floor on rubber mounts fitted all parts to a 3mm alloy plate with defi gold tape under, fitted a large heat sink, and rubber mounted the cradle

This still gets hot so I am thinking that the filter is causing a restriction and causing heat [Think]

has any one got experience with hi flow fuel filters and point out a good one?

cheers [thumleft]

Are you running a through-rail setup?

If so the heat is probably due to the fuel constantly cycling from the swirl pot through the (hot) fuel rail, and back into the swirl pot...your fuel is trying to cool the fuel rail, but the volume in the swirl pot isn't high enough to cope with the heat.

Either switch to a dead head setup, or change the plumbing of your lines so the fuel returns back to the main tank, before being lifted back to the swirl pot- then the larger volume of fuel in the main tank will absorb the heat and you'll see less heat in the swirl pot.

Had the same issue way back when...

Guessing your lifter pump in the tank is running continuously as well (albeit with little head pressure), this is then being cooled by the fuel...but that should be minor compared to heat coming direct from the engine into the fuel rail.

I think your spot on [thumleft]

I am changing the filter as I have no info on it as they no longer sell it so..

I will change the plumbing back to the tank but I will add a fuel cooler to cool it down as much as possible... Winter project getting it ready for next year...

I'd say save your cash- don't bother with a fuel cooler, you don't need it....just adjust your return line and it'll be fine. A fuel cooler is tempting, but in the end it's additional complexity, weight and money- for gains I bet you'd struggle to even measure [thumleft]

So had a few bits come from Torques Saturday and I think I have sorted the problem

I removed to fuel return from the swirl pot and blanked it

put a T with a one way value (no hot fuel can return back to the swirl pot)

reattached the set up so know the fuel return goes back to the main tank

I let it warm up for over a hour and the setup did get warm but I was low on fuel! so the fuel was warm from the main tank.. I will fill her to the brim and that will cool it right down!!!!

But it is a well deserved beer time....... [thumleft]
