noturbo

Hi folks,

Just a quick question as I couldn't find it in a search. I just caught a glimpse of the prodrive p2 on topgear and wondered, which turbo does the Prodrive P2 use? I'm guessing it's straight out of an STI but which one?

Cheers

I would have thought a VF43 but it runs anti-lag so maybe not.

noturbo

Ah I was kinda hoping it would be a vf43, it's what i've just put on mine haha

I doubt it would be a vf series turbo, they would fart their blades out within 5mins!

I thought the car sounded like a WRC and as it was a Prodrive demo car I wouldn't be surprised if they used some of the parts they had laying around.

chopperman

Any examples of when a VF43 has actually done this ??

noturbo

Yeah why would it do that? I know they're not as strong as 20g's and some of the others but didnt the P2 only have around 340hp? My wrx is 340+ and thats with a vf43 with no problem. I gues the anti-lag might put more stress on it but i'm sure it's a little over exadurated about the vf's being so weak

chopperman

i read that the anti lag is better suited to jurnal bearing turbos which the vf43 is. I read all the time peeps saying the vf is not as strong as say a 20g but have never read any examples of a failure. Sure a billet 20g is stronger but that's not to say a vf43 is weak.
There is another thread where its implied the 2.5 engine is weak without forged pistons only for tuners to state they have tuned several with standard internal and there still going strong.
There does seem to be a lot of pub talk and p1ssing matches here with no real evidence sometimes.

I believe it runs a twin scroll engine so its not got a hope in hell of running a vf43

Tony

Excuse my ignorance but i thought twin scroll didnt have turbo lag. The P2 is fitted with " rally-inspired anti-lag to prevent turbo lag". Maybe the twin scroll is the anti lag If they used a single scroll maybe its the VF48?

well i have a vf48 fitted to mine and its flutters like mad

And twin scroll Spec C's have anti lag locked on their ecu's
Remember the P2 was an experimental prototype so why not put as much on it as you could?
Anti lag is still not legal to use on the road anyway, if you hear the P2 you will tell just by that, that its not a single scroll unit, and the base of the car is that of a new age JDM with a fair few more additions fitted

I'm not disagreeing with you but im wondering how you know as i can't find any such info on it. Not even on the prodrive website. Talks more about the drivetrain than the engine.

For a man with quite so many posts Tony, you don't half come out with some garbage

noturbo

Whats the rest of your setup look like? What intake and intercooler etc.

I've got a vf43 with an sti top mount and k&n cone with standard dv, it dosn't flutter atall but you get HUGE induction noise when it's spooling and the standard recirc now sounds like a vta as it gives off a big woosh now, i'd rather have the flutter so gues dv delete is the way to go?

noturbo

Oh and wasn't the P2 made in 2007? I'm pretty sure the 2007 JDM STI spec-c had the vf43 fitted so I still think it's a possibility

TonyBurns

The vf43 is a single scroll turbo, the 2003-2007 spec c's come with a vf36 twin scroll roller bearing turbo, the spec c type ra-r, s203 & s204 come with the vf42 twin scroll roller bearing turbo.

Why its not legal to use anti lag on the road.
You can have it fitted to the car, it has to be switchable, you can use it on track if they let you, you can use it on rally cars on closed road stages, but not on the public roads.

You can find out more if you do the Prodrive tour

I used one before and it hated high boost, even the Vf48 i am using now wont take more than 1.65 without playing up. They wont hold high boost and proper anti lag.


A rally spec turbo would have been used and not something from a road car

chopperman

Yeah but you were saying vf43 chuck blades??? Ive heard of vf22 with fmic chucking blades but not vf43. Your now re-framing your argument by talking about high boost and "playing up". I asked for examples of a vf43 chucking blades !

chopperman

I must go on the tour one day
As for your link, it's doesn't say much, only the car is a 2L. A VF43 would be a turbo upgrade on a 2L so can't rule it out until proof rather than opinion is provided to the contrary.

I was over exagerating when i said that mate, but the Vf turbo's tend to develope cracks when running too much boost through them hence why most are not capable of high power so would not be capable of the performance that P2 produced as it would let go at that sort of power. The P2 was made from WRC spares and from memory the car hit 2bar of boost at something like 2000+ revs.

MartynJ

Twaddle !
No law exists against it, if you can find the relevant law by all means provide the info.

Martyn

I suppose where all guilty of that from time to time, trouble is some people take those opinions as facts when they were far from it.
As for the P2. The one thing about a concept cars is they can put what they like on it as its never going to cover thousands of miles. It's a pity really because i think prodrive would have sold a limited run of p2's quite easily. maybe the price would have been way over the 40k they suggested to get it to road reliability.

'Although if a flame is coming out of the exhaust like a flame thrower it will be an offence under section 40a of the RTA "Using vehicle in dangerous condition ". the same as whip aerials, sharp protrusions, loose bits etc etc.'

This was on a discussion about flamer kits so i guess the same would apply as Anti-lag often produces flames

It has a twin scroll hybrid turbo, I asked the lady when we were doing the Prodrive tour. I got told off for sitting in it though!

I don't think there's a law that names anti lag as such, but I think it's fair to say every anti lag system I've come across would certainly fall under the remit of Section 59, "vehicles used in manner causing alarm, distress or annoyance"

That doesn't change the fact that it's an incredible feature and certainly brings a smile to my face

chopperman

But that's one of those oppressive police state laws that is so ambitious it can be made to apply to anything. You could fall victim to this law by having your radio on too loud.
